Can anyone explain the erratic signal? - Epic 4G Q&A, Help & Troubleshooting

My phone acts very weird and I don't know if it's normal or not. My phone's signal jumps between full bars and then 1 or no bars when I surf the web or send a picture message. It's downright annoying. Sure, it usually sends and receives data, but the fluctuating signal is getting to be beyond annoying. Anyone else having this problem? I'm on the current version of the Frozen Syndicate ROM.

Welcome to Sprint.
We all would like a valid reason besides spring saying "were currently fixing our antenna's."

What he said. This is very common on the Epic. Happens to me a lot =\
Running SRF 1.1.0 as well.

Someone please correct me if I am wrong, but I thought it had to do with the modem builds with the epic. I don't think it is a Sprint universal issue, because I did not have this issue on any of my previous sprint devices (that I remember).

Correct, it's the modem. That's why you see people on the forum complaining about the EC05 modem sometimes because it has signal bar issues, or stuff like that.

My phone does the same thing, even if it's sitting and NOT moving. Even my data speeds fluctuate sooooo much, it sucks. Sometimes Youtube will work great, other times they won't even start to load.

Hmmm...
It probably is the tower. Could be the modem to blame as well. Here in my house, I connect to my Airrave. 98% of the time, I have full bars with a stable connection with relatively consistent fast 3G speeds. The 2%, I get some wonky lag and usually then go and reset the Airrave. Everything works fine after I reset it.
I was just out of town in Vegas over the weekend and I had MAJOR problems sending MMS's, highly erratic data speeds, fluctuating signal, and overall connection problems. That was even when I wasn't holding the phone. Voice data and sending SMS's were very reliable, but forget sending MMS's or having good 4G speeds. I'm starting to think 4G is a drain both battery and money wise. Using 4G is like driving a classic car: It doesn't always start up, they're hard to find, they're finicky; but when it works properly, it's badass!
Random question: Is there an app that has a status bar for sending SMS and MMS's like the iPhone? For example, on the iPhone when you send an SMS or MMS, there's a status bar that shows the status of that message. If it's going out or lagging, etc. Is there an app that does that? I think that's a cool feature. Handcent just has a circular pinwheel, but stops when it goes out.

I would think it has to do with the modem as well. I have an EB13 based ROM, but an EC05 modem. I've noticed similar things, just not very frequently. It's strange...I'll have "great" signal, then for no reason, it'll dorp to 1x coverage and that SUCKS.
I'm thinking of going back to the EB13 modem as most people seem to think it's quite a bit better than the EC05 modem. I do think even that varies from phone to phone though, so I think it's mostly trial and error until you find what works best for you.

I have a fantastic update. Well it is for me, and might be for all f you also. Last night I decided to odin the EC05 modem again. And guess what? My signals beeen great!! Its always constant! No 4bars then zero in same spot no more!!
I already had the EC05 modem before I decided to do this. I recommmend odin'in you modem again!!
BIG NOTE*** I used the phone location for the modem.tar NOT pda.

Try the DK28 modem,I havnt seen 1x not 1x,and I get better battery life,after 24hours (3300mah batt.) I had 1% TWS...

I am having issues as well, i haven't been able to send any MMS for the past 24 hours. Regular texts go through just fine.

I'm having big problems with this recently in a location where I usually get very strong signal with 4G. Can anyone point me to step by step instructions of how to safely and correctly flash just the modem file?

[Q] Missing Texts and/or Incorrect datestamps

Alright so I have a Samsung Epic running the ACS 1.1.0 rom with ext4 w/ journaling enabled, EC05 Modem with PRL version at 60676.
Problem is that for a while now I've noticed that texts would randomly show the wrong date stamp ie usually ahead a few hours OR I might not just get them at all. I've looked around seen that you should update your PRL and profile to fix that problem, but I've done so and it hasn't seemed to resolve itself. I was running the phone on a PRL 60675 before and didn't see a change. I did run the update of the profile but it doesn't give any sort of success message or indicate anything. Sometimes it'll give a network connection failed or similar type message.
Any ideas at to what this could be. I'm tempted to flash the phone back to stock and run with that, but I really like the ACS rom and have no other ideas what I can do.
When im roaming, and i get a text message, the timestamp is always 6 hours ahead. Its a roaming problem, and im stock unrooted.
[sig]Typed by restless thumbs, that are too tired to help hold my bacon sammiches[sig]
pretty sure this is a tower issue and not a phone issue. that used to happen to me on AT&T, and it was always roaming.
Yeah at this point it seems to be an issue with not the rom. I just flashed to the newest stock gingerbread release from ACS and I just got a text message timestamped 4 hours in the future ;|
Best option is to what? Call sprint? Is it more of an issue with reception in my area or something like that? I'm in the middle of the DFW and I fail to see how I can be roaming unless I'm 4 floors under a parking garage.
I would definitely let sprint know. Sounds like there may be a cell site with a bad timezone setting.

[Q] Evo 4G on Boost Mobile Stale Data Connection (Error 104)

My data works. I'm getting 3G speeds (approx 2 mbps). There are NO other errors on this phone except the random Error 104 and only sometimes Error 67. I've updated my PRL to the 11115 version. I can leave my phone on and not touch it, the data connection randomly kicks out, goes stale, the sending arrow is active, but nothing responds. I have to cycle my data connection off then back on, and that usually fixes it.
It does this A LOT. So much so, I put a Mobile Data on/off widget on my home screen. The internet works just great when it works, how can I get the connection from basically stalling out ALL the time?
If you've had this issue, or are having this issue, please respond.
The donor phone was a w385 (which is a 1x phone I know, but again, I'm getting 3G speeds, guaranteed - when it works right, I can stream HD Youtube videos with no problem at all). How can I get this connection to go up and STAY working??
I'm pulling my hair out over this one...
Mine is doing the exact same thing. Started this morning, has been perfect for the month or so I have had it on boost. Its been driving me crazy all day.
Mine's been doing it since I got it. I was primarily in a wifi area, now I'm strictly on 3G and I can't stand it. I'm so desperate for a fix, especially if it's something I'm doing wrong...
Out of curiosity... have you changed anything, like a kernel or ROM? If it's a kernel, what did you change it to? Trying to see if we have any similarities in our setup and work backwards from there...
I haven't changed anything at all. Im running stock rom with nothing but factory updates, have done nothing to this phone except root it before it was flashed. Just went to sleep with it working fine and woke up next morning to this. I haven't been getting the error code today as much but still having to turn data off then back on a lot. im about ready to throw this phone out the window and go sign a contact lol
I'm having the same problem. I just flashed my phone over to boost mobile a few days ago and I had a hard time getting 3g data to work. I was getting 1x data only. So I got the different passwords that I needed and 3g started working. But for some reason, after about 5 min or so, the data would just become stale and nothing would work (web pages, twitter, etc) even tho the data icon and arrows were still present. Its been happening ever since I flashed. I'm not sure what's causing it but if anyone has any ideas I would greatly appreciate a response.

It's your location. I moved from Haslet, TX down to Austin, TX, and I haven't had a single problem in Austin. Just to confirm, I went back up to Haslet, BOOM instantly started happening.
It's an error with the towers in particular locations. I confirmed it by calling up Sprint, and asking them to check in Haslet's zipcode for any issues, and they did confirm there are issues in that area.
I was sooooo ready to dropkick this phone. Sorry for the unfortunate news, but with Sprint's little network upgrade, it's causing these issues.

Thanks for the update man. I was about to go crazy!! Well hopefully they can get this issue worked out pretty soon here because this is getting ridiculous
Yeah I had to update this to let those with the issue know. I couldn't stand it!
Well I'm in Atlanta and mine quite giving error codes but internet is slow as hell right now. it does it at my house, job, our wherever I'm at. 40 miles away and still does it.
That's cause you're still in the same market.

Signal Strength

I'm curious as if anyone else is having this issue, or if there is a simple fix I'm missing. I'm currently on Calk's ICS ROM (FB27) and my signal strength randomly vanishes and appears as if I have no signal. I believe it's only appearance though, as my data still loads fine. It's not a big deal, but it is rather annoying. Is there a way to fix this? Also, I apologize if this has been discussed elsewhere and I missed it. Not trying to be annoying, simple curious. Thanks!

Are you referring to your wifi radio or cellular radio? I see what you describe with the wifi radio on all of the ROMs I've been using. I'm currently on MIJJz BLEND which is based on Calk's FB27 and alot of the time my Wifi signal strength shows 1 bar but when I go to the Wifi settings where it is scanning for networks the same network shows up as 3 or more bars. If I drop and then add the network the notification area shows three bars but eventually drops back to one bar.
But I recall this happening on the stock ROM too.
Haven't seen the issue with the cell radio.

Notice my actual phone signal. It does that randomly. The Wifi signal is always fine, I haven't had an issue with that. I suppose it's just a bug that will be worked out eventually. Like I said, it still works fine, it appears to be merely visual.

I am having this problem as well. I have tried several different modems and several 4.0.3 roms and have had this problem with all of them. I have noticed that my signal strength stay consistently between -100 and -106 dbm even when using my airave.

Yeah, my exact problem. I'm back on Calk's 2.9.2 ROM now. It was bugging me far too much and the GPS couldn't lock either.

Same Problem
I've had the same problem on the same ROM.
I feel a bit sheepish as it didn't occur to me that the problem was only visual...
I have experienced the same thing. My bars come and go constantly... Even if my phone does not move....
I doubt its a bug. I had all types of Sprint phones and they all did that. It does it a lot on 3g. Its like 3g steals from the bars..

It is a known issue with most of the leaked builds that have come out recently. The bars for Wifi, 4G and 3G were all effected by it. It was purely visual. Qbking77 mentioned it in just about every review he did for the different leaks (and it's been thoroughly covered on several development threads).
If you'd like to confirm your actual signal strength, I'd recommend using a third party app to see what your actual signal is.
Supposedly it was fixed in FC15 or FC18 but I don't remember which it was.
Hope this helps!
Are you guys saying this problem doesn't exist on Calk's 2.9.2 ROM? I'm using 2.9.0 (just never updated) and I get this all the time. I think the signal actually does suck though. I see the -DBM changing too. Is the reported dbm visual too? I'm confused. My phone keeps switching to 1xrtt a lot when this happens too. I just figured it was cprint being crappy around here. When I force roam on verizon the signal bars don't bounce up and down like this.

As far as I know it only effects the visualization of signal strength, not the actual signal strength itself. That being said if you're running one of the leaked ROM's chances are that you're probably running a leaked modem too. People are having all kinds of results with the new modems. Try flashing just your modem and see I'd you get a better signal.
EDIT: After flashing the new modern be sure to update profile and PRL.

Phone keeps losing signal

I am on GleanGB 1.1.2 with the EL30 modem.
Yesterday I was out and noticed I kept getting dropped calls. I did not think much about it. Today I am at home where I generally get 6 bars and have no trouble. I am in an excellent sprint area. Today the calls either drop after a few minutes, or I get an error message "Signal Lost".
I have not added any new programs on the phone. I have tried turning the phone off and on, and also bulled the battery.
I do not know if this matters, but Text messages have been fine, I can send them and receive them.
Probably is network maintenance on your area. If it don't clear up in a few days try odining to stock EL30 and see if that makes a difference.
Sent from my SPH-D700 using xda premium
I've had horrible data speeds etc since i switched to the EL30 modem, so I went to FB15 last night and so far, better over all for me. Who knows if any other modem will work better for you, but EL30 just wasn't cutting it for me.
Can I switch to other modems on CleanGB?
That happened to me .. I called sprint and the said they were doing maintenance .. they lady said it would be fixed in a few hours but it actually took a few days!

You can change to any modem you want and it won't impact your rom at all.

Anyone else has this issue with texting??

I've been with the EVO 4g and the EVO 3D and now the SG3. at my job i've never had a problem sending a text until I got the SG3, using the orginal rom or custome rom, they are do the same. I will send a text and alot of times it doesn't go through and I have to keep sending until it goes through, every now and again while sending a text, all my text will disappear and it will tell me by text box is empty. I will then have to reboot to restore all of my text.
right now i'm running Sonic FreeGS3 0.7 with LF9.
If there's a thread about this that I might have missed, feel free to point me in that direction as well.
Thanks.

What kind of signal coverage do you get at your work? Also have u been doing any data wipes with your rom flashing?
I don't have a fix for the stock app, but I can offer you an alternative -
Google Voice can replace the stock messaging app. It's main feature is that it sends texts over WiFi/data so you recieve/send texts faster, especially in an area with good WiFi but bad cell coverage like an office building.
Yes, having this issue today, signal keeps going in and out in Dallas Downtown area.
Glad I am not depending on my data connection right now.
before my signal was 4 sometimes 5 bars with the EVO's the SGS3 I will be lucky to get 2 bars, mostly 1 to sometimes 0 . even though I set at my same desk every day, Nothing has changed besides my phone.
yousefak I will try that again, I think I tried that back in the day.
I came from a nexus 4g and it did it every once in a while, but with the s3 its like ever other text, you can't even get a conversation going because that text errors out and you hit retry like 5 times for it to go through, signal is normal as usual.
This is the only complaint with the phone.
Weird, I haven't had any trouble with text messages so far with the stock app. I have a feeling that many of these issues might be related to the on-going Network Vision work, but it really depends on your area. It could be the phone, but I'm not convinced that it is.
Network Vision upgrades can cause this.
i've had this problem since last month, i'm pretty sure its a network thing, just gotten worst with the s3, co worker has iphone on sprint and it goes through instantly.

Does that still apply if you're not using the Google Voice app to send texts? I'm using GO SMS Pro, but have GVoice intregrated with my account. Didn't know if that was ever the case or not.
And in agreement with the others, very possibly a NV issue...I was going through this a few weeks back here in the burbs of Chicago.
I had this a few times where reception was poor. I typically exited the messaging app immediately after hitting send and this would cause it I think, and now I wait until it actually sends before exiting. Haven't had a dropped text since then.
I have the same problem alot with this phone. I have had it for two weeks now and more often than not text fails to send. I have full signal too. Tower is less than a 1000 feet behind my work. Don't really know why it does this but it get pretty bad sometimes. Very hab to keep texting back and forth sometimes. Sometimes the wife is like HELLLO! Where did you go lol.

This would be nice but you can't send mms on Google voice.
Just an update, i was texting at home last night and all my text went through instantly with no problems. I guess it really depends on where you are at and the sprint tower you are connected to.
dapretendr, same here, works when i'm not at my job, but even at home where 98% of the time it works, I do have about 1-2% where it makes me retry.
I expect it to get better once LTE is turned on here in philly, but I don't think we should have to rely on LTE to get text to work better. This is the 1 downside I've heard on different forums though about samsung, they make 1 of the best phone but the Radio for the signals lack.
