Spint working with LOS customers

I called Sprint today to see what they will do for me since I have LOS. After being on the phone for 1/2 hour. They are shipping me a brand new ET4G. Just wanted to let everyone know so they can try it. I hope my new one will not have LOS.
Also for those how are rooted here is the link to the How to unroot thread if they are sending a new phone.

Do all phones get LOS? or just certain phones?
I get it but once a day or twice. Never had more than 5 a day.

I am on my 3rd phone including the 1 sprint is sending. My first one did not have LOS, but was overheating. From what I am seeing not all phones have LOS.
I have gotten days with no LOS then other days with 10+. It is not fun.

The only thing I get is that my battery is garbage. I dont think it overheats, I do have the Android OS bug that drains my battery.
LOS is not common on my end. Glad I don't get LOS 10+ times, I would be mad.

I had my original one returned form Sprint after the 14 day warranty. I spoke to advanced support and talked circles around him on the problems Im having so they send a new one. Now this new on isnt so much loosing Wifi and 3G like the other one, but it is making me reset it a couple times a day. My original one couldnt keep a signal for more than 5 seconds. IDK if Im gonna return this one or not, I just want a phone that works!!!!

I got my myself, wife and son this phone on October 1. By the next Monday I had returned my phone due to LOS and on that Tuesday my son returned his. My wife has yet to experience LOS.
My son and I both rooted our phones. I have read posts that people who NEVER have rooted their phone have had this issue.

I have not rooted the phone and am running completely stock everything. I have major LOS issues. It seems they start mainly when the handoff from wifi to 3g/4g when leaving home or work and no longer being on the wifi network. I dont have too many issues if I keep wifi off all the time and just rely on the cell network for data.

I am working with someone in Dan Hessy's office and she has advised me there is nothing sprint can do without me taking this into a service center first.

LOLOL! You guys are all delusional. LOS is completely kernel dependent. It is not a hardware issue. There are way too many variables that could influence reception. It's people like you that raise our TEP costs. Thanks!

Then fix the stock KERNEL.
Well lets see here. I paid for a phone and I pay for service. So I expect to be able to use my invesment the way it was intended. Losing my signal 5-10 times a day and having to constently reebot. Not a lot of fun in my book. And maybe unlike some people I can not constently watch my phone to check for LOS. In other words I may have LOS for hours before I even notice it.
I am not one to complain unless it is a legit issue.

Sorry but if a pay $500 is bc I need a phone that works, with no this type of problems and I don't care if is hardware or is the kernel, I just need something that works and sprint and samsung are responsible and they need to fix it and we are not supposed to pay for their mistakes.

Uhh he means it is kernel dependent as in custom XDA kernel dependent.
This problem almost never affects the stock kernel.

Well considering my first phone was an overheated disaster (no root complete stock). The one I am on now had LOS prior to root. So I rooted to hope for a fix. Also read the LOS forums and a lot of un-rooted users getting LOS.

If that was true, I would be a happy customer. I am not rooted, completely stock, and I get LOS.

I 100% agree
the LOS is pretty bad on mine, stock or other kernel, its less on stock though
the only saving grace is that I have quick boot on my home page, and this phone reboots the fastest ive ever seen, on any of my smart phones in the past
I just get concerned sometimes, since I have kids that I may miss messages or something
its still a killer phone though,

As much as I hate to say that replacing the phone isn't likely to fix the problem, I do encourage it so Sprint will push Samsung to fix this issue quicker. The more phone replacements, the more sprint spends money on replacing. Also, if it ends up costing more than simply fixing the problem in the first place, they'll be forced to fix it.

Stock is not a phone that was rooted then loaded a stock kernel. Stock is an untouched device that has never been rooted in the first place. Based on my personal experience, true LOS with the zero and line do not happen on an out of the box untouched phone.
My untouched phone had no LOS for 4 days until it was rooted. Next 2 days had an LOS each day. Got a replacement phone last Friday. Kept it stock and haven't seen an LOS yet. That would be 6 days without an LOS.
I am convinced it is only happening on rooted or once rooted phones. If I get an LOS I won't be afraid to report it here but I am pretty confident I won't see it. I have used my phone in the exact locations and same instances so far and still no LOS.

I agree. I'm totally stock and I've had the LOS problem mind that it was 3 times now 3rd time being today as I was walking back into the APT and the call just dropped as I looked at my phone there was ZERO signal when I had full bars just seconds before that. So far it's not been as bad as others are having so I've not really looked into getting the phone replaced yet but it's something that I do keep my eyes on to see if/when I'm getting it and how often it might show up.

I have a totally stock phone it's never been rooted since the day I got it almost 2 weeks ago and I have had LOS on it. I honestly do not think this is a rooted phone issue if that was the case I would never of had it at any point in time and I have. And like I said Stock never once rooted and have not thought about doing it yet.

Rooting Leading to LoS

I rooted my phone for the first time yesterday after having it for two weeks. I never had a LoS issue and was getting 3 days of battery life. About an hour after rooting, I got my first LoS. I charged my phone overnight, and verified everything was okay in the morning (had sync). After 6 hours of being at work, I got a low battery warning and noticed it hit LoS again.
I know people with stock phones have reported LoS, but I'm convinced that it's either significantly worse with a rooted phone.

install starburst v1.6 which includes lost kernel.. lost kernel fixed my LOS issues.. maybe it will do the same for you..

Question: I flashed the stock kernel from Bubby to get rid of the LoS problem. Everything succeeded, but I still have root. How is that possible if I put the stock kernel in?

It has absolutely nothing to do with root.
That is nothing more than a rumor.
Developers have stated, and so has Sprint, that this is a problem with the Samsung firmware with the phone.
If this is true it was just a mere coincidence.

I believe you, but I also believe it's worse with rooting or something caused during the rooting process. I had the phone for two weeks and never once saw a LoS. I rooted it using CWM + su, and had 4 LoS over the next two days. It just seems like too big of a coincidence.
ripalsanghani, no I didn't flash a ROM

root does NOT cause LOS. It happens on stock firmware also. It does happen more tho after you root (seems like it)

If it doesn't, then it definitely makes the problem EXTREMELY worse.
I've had two EPIC 4G Touchs (replace one before return policy ended because of stuck pixel) both phones I had running for about a week and half before rooting without issue.
Both immediately had LoS after rooting (and frequently.)
Haven't tried the newest kernel that is supposed to be much better though.
I'll probably feel brave enough soon.
For both phones, they immediately were better after putting stock kernel back in place. So YES definitely the previous kernels at least were either causing or exacerbating the issue. I've been able to recreate it.
I hope the new kernel is better.

100% rooting was the cause of my LoS's.
I had the phone for 2 weeks before rooting, not a single time did I have an LoS, and I was on the thing pretty much constantly. I rooted the phone, tried all 3 of the popular roms out there with the zedo kernel, 30 stock, and stock, and within 2 hours of rooting I had an LoS. After a few days, it got worse and worse, I would get LoS's at least 3 or 4 times a day, and I'd wake up every single morning with it having LoS'd over night.
I have since gone back to stock with the image available on XDA about 4 days ago, and I haven't had a single LoS since with no change in usage and all the same apps and settings as I had before. The only change was no root, and stock image.
It's too bad, I really loved my Evo and how responsive it was to rooting, kernels, and roms. I love this phone, I hope they get this part worked out.

LOS definitely can happen with stock kernel+stock ROM, but it happens in much fewer cases.
"Root" doesn't cause LOS.
However, many methods of "Root" include a "recompiled" kernel from Samsung stock source code.
It is the "recompiled" kernel which can in some cases exacerbate LOS. In cases where people were already seeing LOS, it could get worse. For people who never saw LOS before, they could start seeing it. There is an attempt to minimize the LOS effects in the "recompiled" kernels. It is called lostkernel.
It is unclear whether LOS getting exacerbated is due to Samsung source code being problematic or the build parameters being slightly off from what Samsung originally used.
Also keep in mind on Samsung Recovery and Android use the same kernel. On other platforms, Recovery and Android are separate so the kernels can be updated independently. What this means is if you install a Custom Recovery, your Android will also start using whatever kernel it came with (because there is only one kernel for both). Up until recently (as in a few days ago) every Custom Recovery came with a "recompiled" kernel so you might have been using a "recompiled" kernel from stock sources even if you didn't realize it, especially if you came from another platform expecting Recovery and Android to have separate kernels.

Good explanation - that being said, at the root of the issue, no pun intended, after having rooted/kernelled/rom'd my device, I started getting LoS's, before, and after, I haven't had a single one.
Just hope they get it worked out, blame isn't something I am throwing around or pointing at, if it gets fixed, that's all I care about It's a great phone, best phone I've ever used by far.

It's definitely not the rooting itself, but rather the recompiled kernels that seem to cause the increase in LOS.
There are non-kernel roots in the dev forum that don't have this increase in LOS behavior that people complain about in the custom kernel threads.

Maybe I'm just new to this, but I don't believe I flashed a new kernel. All I did was install CWM, then flash the su program. This is when the LoS started for me.

Which CWM did you install? Every CWM except the repacked one from chris41g that came out 2 days ago includes a "recompiled" kernel.

It was the one referenced in the thread at the top of the development forum summarizing the status of everything.

LoS with root

I've had my Epic Touch 4g for about 3 weeks now and I have noticed something outside the normal LoS threads I've seen lately. I only seem to get LoS when I flash kernels, mainly ones with CWM 4 or 5 or ones that are rooted.
The issue clears up as soon as I flash the stock EG30 rom. It's the same deal with either EG12 or EG30 modem.bin.
Not really looking for answers, I can wait a few weeks for you guys to work your magic. I just wanted to set a precedent with my own experiences.

I better hurry and comment before this one gets locked.
I've owned the phone for a little more then 2 weeks. I have had a total of 4 LOS events. 3 with a Zedomax kernel(all in the same day) and once with the latest lost kernel experimental. For the last week the lost kernel stable has had none. Can't comment on unrooted los because my phone was only stock for 15mins after unboxing.

haha yea my phone lasted 15 minutes as well from my boys house to mine..lol @OP I am not sure how much reading you do on here but I hear a whole lot of stories of people who get LOS and there phone has been untouched. I have a friend who has had the phone for a month or so and has only had 3 LOS but all from the same tower(phone rooted).
Don't try and figure it out, sit back and wait for an answer, return your phone if you like or sell it but unless you are a developer or know about phone software and you have a solution. I personally think we should refrain from making statements we are not 100% sure about. IMHO
NoT trying to be disrespectful but its a pretty touch subject in here and honestly you are like the millionth person to say the same thing in a new thread....lol

As far as "here's my proof with evidence in anecdotal form" is concerned, that precedent has already been set.
The facts are this:
1.) Untouched stock units have had LOS (mine included).
2.) Samsung seems to have released incomplete source. What is missing (whether it is in the source or in tool-chain/build parameters) is unknown.
3.) Kernels built from said source seem to exacerbate the problem
4.) You can have root AND the stock (pulled) kernel.
5.) Root binaries and/or busybox do not cause LOS.
6.) rooted+stock kernel installs seem to have the same occurance of LOS as bone stock, uninformed alarmist anecdotes notwithstanding.
7.) This has been covered in over 9000 threads already. Please search in the future.
8.) Samsung and Sprint are aware of the issue (in stock phones) and are issuing inconvenience credits if pressed and are supposedly working on a firmware to fix the issue.
Please pass this information on to the next student of science who presents his "proof" of this "discovery", as there will likely be more.

Now how do you like them apples ......my boys wicked smart .....
Good will hunting
But seriously please search and find the previous 50 threads that say the same uninformed thing ... If it was only a root thing would Samsung be fixing it ..... Hell no

I have had my phone since launch day and have only had LOS one time when it tried to go into roaming and never got back a signal. That was shortly after I rooted with a stock kernal. I have not had LOS since but I have never flashed a custom kernal or ROM. The phone has been mostly trouble free.

Where did you find the EG30 modem bin?

Ditto. WTF SamSprint?

I looked into this more late last week. The kernel source is complete. I'm not certain that it's unmodified, but I'm no longer certain it's modified either. The majority of the difference between EG30 and source-built kernels is a bunch of debugging options that Samsung left enabled in the kernel defconfig--options that alter the core behavior of the kernel enough to plausibly exacerbate a code bug.

Thanks for the informative post.
I've been on Starburst+LoSTkernel for almost a week now with no problems. Before that I was strictly a pulled-stock kinda guy given my experiences. But I'll give that a shot and let you know. I get very infrequent LoS with stock kernel, though they do happen once every 2-3 weeks...usually a few times that one day. So, in a few days of very routine use (location/tower/times always the same, to a tee) I'll have a pretty good idea, assuming randomness doesn't factor into it as much as it could.

I've been using it since I posted my last reply last night. No more LOS than stock so far...and typically with the Samsung-source compiled kernels I've used I would have seen at least one by now.
I do get reboots after I get some texts, but, every other kernel (even stock) was doing this...I think it's the ROM...so, don't even worry about that. Later I'll nandroid back to my original stock install and flash this kernel on top and report back.

That's good news.
My goal with that kernel is to just be stock, so if it's indistinguishable from stock behaivor wise, that's a good thing.
LoStKernel may have made much of the source-based problems irrelevant. But perhaps the defconfig changes may still prove useful.

Just to keep moral up I want to specify that "no more LOS than stock" means "stock rarely gets LOS and so far I have gotten absolutely none."

Anyone Still Have Their Phone Unrooted / LOS Bug?

So I would like to know if anyone out there besides me has not rooted their phone yet and if not, have you gotten the LOS bug?
I had purchased an E4GT when it came out and ran it stock for about a week. Did not have on LOS. Then decided to root it and within 12 hours I had an LOS. Within another 12 hours I got another one. Nothing in my use had changed and it happened in my house both times so it was not like I was in another situation that I have not been in.
I exhanged the phone for another one and obviously did not root it this time around. It has been over a month now and I have yet to get an LOS. I have traveled in areas where there is no Sprint service, through farmlands, etc. My phone roams fine. I have been on 3G, 4G, wifi, and an airave and there is nothing that will give my phone an LOS.
I also have a friend who owns the phone and I refuse to root his because he also never got an LOS since release day and I would be willing to bet if I rooted it one would show up not long after.
This is not to bring out the haters but I want to hear from people who have never rooted their phone. Not the ones who rooted then re-installed stock. I am sure we will also get some liars in here but I usually can pick out the trolls.
This is for true LOS, not that your internet connection wasn't working or your calls went straight to VM. I have had things like that happen for years already on all of my past phones.

Never rooted, never had LOS. Damn do I miss wifi tether.
You have been Epicly Touched by Jesse Buck

Yes I'm not rooted and I have gotten LOS. Not as of late (for over the last week) but I've had 4 total the 4th one I really can't blame the phone or Sprint since everyone at the time that was/is on sprint was having the issue (20+ people I go to school with)
Outside of that I've not had an issue as of late but yes I've never been rooted and I've had LOS as have other people in this forum as well.

I do not have LOS with Chris41g's kernel.
My brother who is completely stock/never rooted gets LOS from time to time.

Never rooted, and no LoS for me.

Couple of weeks. I find the newer versions are better than the old.

I haven't rooted yet and I haven't had a single LOS since I got the phone on release day. That's the only reason why I haven't rooted, I'm afraid that if I do then I will start getting LOS. I wish there was a root method that didn't involve flashing anything, then I would pull the trigger on it. But for now, tethering and adfree are not a compelling enough reason for me to root and deal with the risk of LOS. I see no reason to flash a custom ROM or kernel on this phone seeing as though it is fast as hell and butter smooth the way it is. I would like to delete some crap from it though.

Totolly Agree and feel exaclty the same way. Although, even with the crap on it their really is no negative effect on the phone at all.
I am willing to say that almost everyone that has rooted their phone has seen an LOS where the ones that never did will most likely never see one.
Everyone is *****ing about Samsung that really is more of a rooting issue and not a manufacturing issue. I hope this gets sorted out and whatever Samsung updates will fix the issue with root. I can hold off for now but once an ICS Rom hits, it is going to be much harder!

Had this phone since launch and haven't rooted yet. No LOS at all. Phone goes on roaming and out just fine. First phone I have had stock but this phone is a beast. Will root once the LOS is solved or there is a rom that I can't wait for.
Sent From My Evo Killer!!!

I got the phone on launch day, LOS (stock) started on day 3. Rooting didnt help. Took it back for a replacement and havent had LOS at all... I rooted/added CWM yesterday, no issues. BUT, I havent flashed a rom yet, and I wont until this "update" is out...

I was stock until 2 weeks ago, and I've had the phone since one week after it came out. On stock, I had LOS 1 time. After I rooted just two weeks ago, I've had it 2 or 3 times.

I am willing to say that almost everyone that has rooted their phone has seen an LOS where the ones that never did will most likely never see one.
Everyone is *****ing about Samsung that really is more of a rooting issue and not a manufacturing issue. I hope this gets sorted out and whatever Samsung updates will fix the issue with root. I can hold off for now but once an ICS Rom hits, it is going to be much harder!

If it were a rooting issue and not a manufacturing issue, then why is the manufacturer admitting that it's a manufacturing issue and releasing an update to fix the manufacturing issue? If it were a rooting issue, they'd have said "don't root and you won't have the problem".
I didn't root at first for fear of LOS, then I got it twice on the 4th day after release so I rooted anyway. Got it 1-2 times a day for a few weeks. Started running chris41g's lostkernel and now I get it once every two days to once a day tops.
Can't wait for Samsung to fix their stock problem at least they're on it this time and not screwing us like the epic 4g...which just got gingerbread i heard.

Not rooted, have had the phone since the week it launched - experienced LOS ONCE while in my house on the couch where I use the phone a lot. Haven't seen it since. I really, really miss being rooted mainly due to wifi tether and hiding annoying ads but I think the biggest thing right now is the effing camera click sounds.
I really wish there was a simple, straightforward root process that just "unlocked" the phone without really changing anything. Is such a thing even in process? Until then, I'm likely not going to do jack because LOS problems would be a ***** compared to the annoying camera clicks.

Flashing may trigger LOS, but it is not the root cause (no pun intended). My phone is bone stock and had LOS bug pretty bad. Even happened in a Sprint store while I was showing them.
CS had me do a data profile clear/re-update and all has been good since.

If you think rooting is the cause of LOS you're wrong, plain and simple. Some kernels may cause it to happen more often however. I had it 4 or 5 times when stock. I'm rooted now with chris41g's stock pulled w/cwm5 kernel and haven't had LOS since. I won't be surprised if I get LOS again, but it's definitely not because I rooted my phone. It's a problem right out of the box

Once again, root (su binaries and busy box, typically) DOES NOT CAUSE LOS.
The phones can get LOS bone stock. Mine did.
Custom kernels seem to exacerbate the problem...though new kernels seem to have figured it out. (current kernel is over a week in use with no LOS...as good as stock)
You can have root with a stock kernel.
You can debate LOS occurrence frequency differences between stock and custom kernels but please get your terminology straightened out. All of this is causing the conversation to always turn into a debate into an argument, every time and scaring people who want to root...and them the conversation comes back, the cycle persists and just gets louder every time.
Get your terminology straight...
...root has nothing to do with this. Period.

Thank you - that is what I was wondering. I understand what you're saying about rooting not being the cause of LOS but, as you said yourself, some of the kernels used to root these phones seem to exacerbate the problem. There are a few different camps of thinking here and one of them is the group that almost never or never experienced LOS out of the box. To them, the link between rooting and seemingly more frequent occurrences of LOS is enough to make them hesitate to root. Another group are those that experienced LOS already and maybe have nothing to lose to rooting and seeing what happens. I can tell you that, having experienced only one LOS since launch on a stock GS2, if I were to root today and experience LOS tomorrow I'd just have to link the two.
I'm not very knowledgeable on the rooting process but I have rooted almost every android phone I've ever had: Hero, EVO, Photon. ... I'll have to read up on which of the latest root methods for this phone seem to be the best as far as not experiencing LOS and maybe I'll just give it a whirl and see. If nothing else, it'll add to the body of knowledge and experience for this phone.

I'm a month into ownership and still no LOS. Been rooted on and off for 3 weeks and have run both types of LoStKernel and the Stock Pulled Kernel. I've flashed back to completely stock unrooted twice to have a clean slate to work with. No issues yet.

LOS some ideas and thoughts

I've read these forums since they were put online and I've followed all the issues with the phone even before I got it. I knew about the LOS issues and even with it I got the phone. While I've had LOS a total of 4 times even before I rooted my phone after rooting it I did notice it a bit more.
kinda going to reference this thread that was just brought up.
http://forum.xda-developers.com/showthread.php?t=1360375
Now normally I would not really post a thread but I do have a few ideas after reading a lot of the things on this forum over the last few months. I remember reading that the source that samsung released for the phone was not correct(correct me if I am wrong here) Was something about it not matching the md5 check with what we have on our phones exactly (ie sounds like samsung left things out or maybe they put up an old source code?)
But this got me to thinking after rooting the phone the other day and noticing LOS far more then I ever have (10 times within 4 days and this was running Calk's rom granted all roms do have the issue not trying to single any one rom out by any means)
What if Samsung actually did something within the kernal itself (and they left it out) that either beefed up the radio for cell signal or something along those lines yet they left out "their" code for doing the same thing for rooted phone on purpose? Don't get me wrong I do love this phone rooted or not (which I currently went back to stock without root tonight)
My reason for bringing this up is this. While I was un rooted (regardless of seeing LOS or not which I did) I noticed a few things between stock and root when it comes to phone signal. Even before rooting I've never really had many issues with my phone in my APT never once had LOS yet after rooting I did. I normally put my phone in one spot while I'm on my computer I don't pay attention to it much cause if I'm online I normally am not going to be on my phone yet after rooting the other day and doing what I normally do with my phone a few hours later I went to leave and picked up my phone and noticed I had a LOS and it had been there for awhile.
Now this is normally a spot where I get full 3G bars and NEVER have any issues at all yet after rooting it showed up. After going back to stock tonight I did what I would normally do and no LOS in sight. It honestly makes me wonder while I know a few people are having the LOS issue even with the stock rom (I've had it) it would seam that after rooting it comes it far more often then not which I find very odd why would "root" cause this issue and on top of that why would the 3G signal actually drop from Full bars to 2-3 bars in the same spot. It's almost like Samsung in general did something with the Android Source and the radio together to kind of deter people from rooting.
I dunno just some thoughts I had mind you it is 5am here and I am a little tired so not all of my thoughts are totally there and kinda scatter brained but this just crossed my mind and figured I would bring it up and see what others might think about this.

Seriously, you wasted all that time posting this this when you should have just went to bed?
Next time you have the choice to post something like this or to just go to bed, choose go to bed...
-> eman is very mean this morning. I need to be nice, it's Thanksgiving and all my posts since I have awoken have just been mean!
Going to try and be nice the rest of the day! Happy Thanksgiving everyone!

Yes thanks for being an ass and not even actually contributing anything. Great work in that department.

Update your modem to eg31, go back to stock kernel. If you have los go into task manager and clear ram to get rid of los. That's all we can do now to limit los until we get another modem update. Los happens if your rooted or not, some more than others

Ontop of the los its bad enuff that samsung makes poor radios in general compared to moto and htc.. i believe even if the los is fixed the ooor radio build that samsung is known for will still contribute to problems ... if they had the radio strength of the photon the epic touch would be far superior ...but until then we need a phone to function and act as a phone and sgs2 wont ...

Nice thought, but the reality is that there many, many stock phones with LoS. The only reason that there appears to be more issues with rooted phones is that most rooted users are using custom kernels. Go to a stock kernel and watch your LoS drop back to the same level it would be on a non-rooted stock phone. I have the luxury of having a stock phone in the house along with my rooted one and I have been able to verify this in realtime on an ongoing basis. To the point that I can definitely say that my wife's stock E4GT experiences twice as many LoS incidents as my rooted E4GT running the Rogue Stock 1.1 kernel.

I couldn't disagree more! DO NOT update to the EG31 modem and then go to stock kernel. You may be asking for trouble and since there is no going back from EG31, you could be stuck in a bad way as many have reported.
What you want to do is flash a stock kernel with your current setup and give it a few charging cycles/days to settle in and see if that helps. If not try some of the other posted fixes for data and signal. There are many. Some in my signature.
If none of those work and you feel like you have too many LoS experiences and poor data, then you could try flashing EG31 to see if it helps (knowing in advance that it is a one way ticket and you'll be stuck on that modem until someone figures out a way to provide the EG30 modem or some official source is released.) Might also make it difficult to return the phone for any reason as you will never be able to get back to showing the stock EG30 Baseband in the About phone menu (though most techs won't be savvy/care enough to check.) EG31 works great for me, but it does not for many others.
It's been crazy watching people flashing modems for no good reason and then *****ing about the outcome.
Reading first is better than flashing first 100% of the time.

Haven't had one Los on stock kernel, vipers fix works. End. feels good to be unbanned and able to help

OP, while we do appreciate your efforts in the brainstorming department you could have picked one of the hundreds (literally) of threads discussing this to post in.
A few things:
1.) Rooting does not cause LOS
2.) Stock phones get LOS
3.) Custom Kernels seem to increase LOS occurance
4.) You can be rooted with the stock kernel (and have the same frequency of LOS as pure stock)
5.) Some people are more heavily affected than others
6.) Being in a fringe service area seems to make it worse for some but not others
7.) This has all been discussed ad nauseum
A few other things:
1.) mkasick built a kernel to be as-stock-as-possible. I ran it for almost 2 weeks without a single LOS. I am now running it again. I got less LOS than stock (which was infrequent but did occur), but, I'm going to stick with calling it 'as good as stock' LOS performance.
2.) chris41g has integrated the changes mkasick made into LoSTKernel experimental builds. Others may have as well.
3.) Different phones seem to have varying levels of susceptibility in the same physical area with the same configurations...It appears there may be a hardware component to some units.
4.) Whether Sprint/Samsung's update can address all of these issues (if they are even separate issues at all) remains to be seen.
5.) Don't screw with flashing modems unless you know what you are getting yourself into. (I, personally, am having an awesome time with EG31 modem and mkasick's kernel....others are experiencing nightmare LOS with stock kernel). There is no going back to EG30 modem yet

Yeah, I got lucky I guess. I am one of those who has better results on EG31 but I wasn't at first. I was quietly regretting my decision until Chris updated the kernel to EG31 w/CWM5. If you aren't having severe LOS then stay put and experiment with different kernels. I was not happy for a few days as I didn't have LOS to begin with, I thought it was the fix and jumped in immediately. Thankfully things have really stabilized and actually improved for me

I took a few days to think about it and gauge the responses from others since I actually have almost no LOS problems stock, none on mkasick's kernel and very very very few on LoSTKernel exp. But the vast majority of issues seemed to be from people who were on a custom kernel. The rest that were on stock kernel seemed to match the percentage that is screwed no matter what so I jumped in. I'm glad I did. I haven't ventured off of mkasick's kernel, LoSTKernel exp will be next up. That kernel just flies...
Either way Wifi and 3G performance is better, but, I would not recommend anyone to flash EG31 modem...make risky decisions on your own.

Yeah, fortunate for us, it has worked out for the better but if you do it, know that you have to live with your decision until the next update or go to EG12.

+1 Pretty much wrote the same thing one post above yours. I think it is very good to repeat this point over and over. I can't believe that people still flash **** without any pause nearly 4 years into Android's public existence. I've spent the entire week helping people who flashed the EG31 modem without even knowing what a modem is or what it does. And then seeing people recommending EG31 left and right as a fix for everything from slow data to gout. Of course not warning anyone of the fact that this is a flash of no return. It's crazy.

There has been a development today on the LoS issue, someone in the dev thread (sorry, don't remember their name at the moment) found some interesting things in the logcat that occur only when LoS. I plan to work on the script tonight and get another build out. Stay tuned

It was trifthen and yes he did find some interesting info. I am very curious to see what happens when you integrate that into LoS Checker.
I also have to say that you continue to impress with your unending spirit of cooperation in everything you do. I remember that same spirit everytime you were around at MIUI.us and was appreciative of it then as I am now. More about advancement, less about ego. We need more devs like you viper.
