Change the rate the phone searches for a signal - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

I work in the deep interior of an old hospital. Battery life outside the hospital is stellar. I can go all day and use the phone however I want and only be down to 65-70% at the end of the day.
However, during the work week, my phone is down to 30-35% by 4pm when I go home for the day.
I know this is because the phone spends the majority of the day searching for a signal. I teeter between 1 bar and no signal for the majority of the time, which is fine for receiving calls/texts/emails.
My question is there a line in a system file somewhere that dictates the rate at which the phone searches for a signal?
If so I would love to change it.
I have tried the 3g/4g only APN(At&t, btw) with no change.
I tried several searches with no results. If this has been discussed before, please, someone link me to the thread.

battery problem

I Got my TP2 on sunday, this is actually my first post.
Flashed it with NRG's Photon rom
roms:
trapster
HD tweak
HD softreset
acbPowermeter
am about to install wmlonglife to see if that helps...
DX drivers
(those are off the top of my head)
Yesterday my TP2 (I flashed it yesterday at about 3) was at 10% when i got home from work, charged it over night, it was at 20% at 2 oclock when i got out of school, plugged it into car to charge, went home, now at home its been sitting plugged into my computer for a good hour, its still at 20%...
I understand with more 3g usage or just radio usage in general it drains faster, but this is ridiculous... it would be dead by 4 oclock
the highest ive seen my mA's at are around 500 just now glancing at it, its avg is 350 mA
anyone know whats going on?
also may be related, sometimes i wont get a message until I go to send one, and ill recieve like 2 from the same person at the same time.
I have AT&T
on the 3rd post or so of NRG's rom thread is valuable information regarding battery drain issues. One of the most popular is that the rom is calibrating/adjusting to the battery level, so it will take a charge cycle or two for it to give you an accurate reading. I'm currently on NRG's latest rom and have no significant battery issue.
As for the sms, it could be a network issue, and knowing at&t wouldn't be surprised if it is, but i'd recommend to soft reset just to be safe.. I've had that happened to me several times before on a couple different devices. You can call at&t and ask them about network issues in your area and they'll notify you if there are any, or if they're doing upgrades, if its none of those, then could be something with your device.
thanks for your response!
are you referring to this thread? *edit* because im new I cant post links...
any chance you could gimme a resource?
I couldn't find said info...
I did a soft reset, if the problem persists ill contact att. now if only i can reorganize these messages... I hate how you have to click newer several times sometimes in order to get to the current text...
thanks again for your help.

Navigation crashing

As if the poorly engineered radio and antenna weren't enough, my Nexus has crashed and rebooted multiple times during navigation. By the time it rebooted and finally grabbed a weak 3G signal, I had already missed my turns.
Fvck you Samsung. Stick with making toasters. Leave the engineering to Motorola and HTC.

OK. First, you should relax a bit. It's not that a big of a deal. It's a first gen ICS device so you shouldn't be too surprised by teething pains. I just used Google Nav to drive cross-country and let me tell you, it worked pretty darn well. It did freeze up solid once which required not only a battery pull but a "time out" before I could get the device to reboot. All was good after 5 minutes. Other times, I had to use the task manager to kill previous instances to get it to work. Not bad for 3,000 miles of travel. Didn't miss a turn. Had good signal. Only a little GPS drift a couple of times which makes me wonder if the GN GPS supports WAAS. Doubt it. Either way, it is miles better than my Galaxy S which frankly, isn't saying much, but still it was miles better.
On my trip, Google maps pulled in 1.10Gb of images and I got three warning messages from AT&T. One told me I should use WiFi because I was close to being in the top 5%. Another told me I shouldn't be tethering (which I wasn't... this week). And finally, I got a message from AT&T that said they were suckers!!! Going down to AT&T today to rough them up a bit.
Never noticed any crashing here in the UK whilst navigating either. Maybe its linked to a poor signal?

no crashing here in Canada... used it for about 2 hours in city driving

2nd Nexus - reception still sucks

I burned through my extended battery in 2 1/2 hours today, and 4g drops were ridiculous. I finally called tech support, and they told me to exchange for a new one. So, I got my second one, still getting 4g drops. My wifes Thunderbolt (my old phone) holds 4g full strenght in my house all day. I am highly disappointed in this phone. If Rezound gets s-off by January 15, I may be switching. It sucks, because I really like this phone other than the signal.
Also, when I talked to tech support, she said there is an update coming in March, which I also read elsewhere on these forums. Why would they wait until March, seems kind of wierd.
I always read about people complaining about this phone. I have this to say to you:
If you don't like it get another phone.
I'm sure there are plenty or Rezounds out there for you.
Haven't you guys read that the LTE network has been on the fritz?
Sent from my Sensation using Tapatalk
Cool story bro.
Sounds like an issue with the LTE tower near you. My reception has been great. I'm at 14 hours and I still have 19% left...barely had it 24 hours. If you have multiple phones wigging out, there are two possibilities:
1) The User
2) The Network
Let me guess, you restored all of your titanium backups and/or restored from Google Servers?
Here's another thought. Did you get a new 4G Sim card or did they just pop the old one into the new phone? Ta-Da.
Omg so many Verizon-noobs complaining, of course it has bad battery, it's LTE...
By the way i dont believe you in going from 100% to 0% in 2 and a half hours with two different batteries, unless you are dumb and has screen on 100% etc. If, however, you are serious, call Verizon or something.
Actually, half you guys are arrogant assholes. No, I installed everything fresh, my f*%$ing Titanium files wouldn't transfer from old Nexus back to my computer without hanging up. Yes, I have a high-end computer with no issues, yes the samsung drivers are installed, MTP sucks. Yes, I owned a TB since day one and never had 4g reception issues in my house. No, there are not tower issues, I know how to troubleshoot. I get 10mbs down on both this phone and the TB, except the TB doesn't lose its 4g signal. And yes, I got a new SIM card with my new Nexus.
Plus, I work downtown on the 33rd floor, and my TB held a 4g signal most anywhere in my office, even in the ****ter in the middle of the floor. My Nexus, burned through the battery twice in 8 hours and was in 3g half the day. But, I guess it's user error. It's clear as day there are issues with reception, it's just can you tolerate it.

No one said I burned through 2 batteries, I said I burned through an extended battery in 2 1/2 hours, screen is on auto, and you are an arrogant prick also. Do you assume everyone is dumb because they have issues with their phone? Also, I have been on 4g since day 1 with the Thunderbolt, I know where f##$ I get 4g and where I don't.
I had a little over 12hrs 36min with minimal usage in an area with known bad signal and had 21% left today, go figure i guess. Granted I only used my phone during my breaks and lunch. Still good for being connected to LTE all day imho. Im happy with the results I've had and I am totally realistic with battery life with an LTE phone, so much so i bought the extra battery+charger. If i happen to be in an area when I know I won't have the option to charge my phone, i swap the battery and have near full charge. It's awesome.
Software issue. Go cry to VZW please.
Yaaaaawn. User err... ogance.
Crazy world, ay?
You guys really are being dicks.
First off, it's clearly not the distance from the 4G tower because the thunderbolt is working just fine.
Second... the guy posts here saying he's had trouble with his second device. And being that an older device is working just fine he's looking for some answers. He's not trying to craptalk the device, but looking to see if anyone else has had the same trouble. That way in can gauge if he should attempt to get a third replacement, or swap out the phone for another device... or maybe someone figured out an issue with a specific ROM or discovered a radio that fixed his issue.
Instead he gets you Trollolols that are being complete dorks by telling him to switch to rezound or cry to VZW.
If you have nothing substantial or beneficial to say to his predicament, why is it so hard to just to stfu and move along?
Take that crap to androidforums.com where it belongs.
To the OP... have you attempted a different radio? Here's an article on it.

Gall0ws, thanks for the links, and support. I actually flashed the new radios on my last nexus, didn't get much of an improvement. The TB is between 75 - 85 dbm in my house, and the Nexus (including the new one), is typically between 95 - 115. I don't even care about the reading, because when I have 4g, it's fast. It's the drop outs to 3g that suck. Also, going to monitor this device for a few days before I flash the new radios, so I can really say if they made a difference. This just sucks, I was really hoping for an improvement over the Tbolt.
kwkslvr, I will take the screenshot, then punch it in your face. Do you think I am exaggerrating? Do you think I felt like taking all the **** off my phone, reflash everything back to stock and relock it, then waste an hour at Verizon, then reroot and put all my **** back on, I have no time for that. My thunderbolt is the original day one issue by the way, I don't exchange things for no reason. I don't use Titanium for anything other than restoring certain apps that I have that are no longer in market, no data.

I haven't had problems with my GN, but I did find these two articles interesting regarding the whole 4G problems w/ some GN owners. I'm sure it isn't any condolence but...
1.http://www.droid-life.com/2011/12/2...accurate-than-others-there-may-be-no-problem/
2.http://www.droid-life.com/2011/12/2...gnal-indicator-to-better-match-other-devices/
What I find most disturbing is VZW "fix" for this is to just change/ fake what the signal actually is at and they aren't stating if the GN is correct or incorrect?!?! lol
By the way, when I got approval from Tech to exchange my device, she said there was an update coming in March in regards to the signal display issues, seems odd they would wait til March for an update. Just repeating what she said, nothing more.
Here is a speedtest with my signal strength, speeds are fine, and I am reading 101 dbm.

The fix might not be simply falsifying any data but perhaps correcting an issue where the software is improperly calculating it. Which of course could lead to a lot of other issues such as excessive power drain because the phone thinks it needs to increase the power to the antenna instead of leaving it alone or reducing it.
For anyone having an issue with their signal, just keep a close eye on the radio threads. As soon as a new one gets leaked, they'll post it up and you can try it out.
And it can take a while, for example, my thunderbolt didn't have a good radio until on that was leaked Fall of this year. There is no rhyme or reason to it. some radios work better for some and not so good for others.
Obviously, if the phone isn't usable for his area, march is a long time to wait for an official update for verizon. But typically this stuff gets leaked out before an official push anyway.
Anywho, JC. Thanks for the links.
No major problems here
I've been running my phone for 2 days here without any significant battery issues; at least none more that I expected based on battery size and playing time. I've ordered the extended battery for insurance, but I fully expect that to do what I need. My only complaint at this point is signal strength vs. other VZ phones I've seen sitting right next to me. I have being disappointed here, am I alone?
Feel free to take a swing, but I don't think it'll fix your GN. I'll be awaiting the screen shot.
The AnandTech article is completely correct. I experienced a similar thing with my iPhone back in the day. This is a GOOGLE phone with as little Verizon interference as possible. Carriers want their users to think that they have GREAT reception everywhere they go. Those numbers are typically fudged, it's nothing new, I promise. As far as 4G drop off to 3G goes, most LTE phones suffer from this. Your T-Bolt is an older device. I'm sure you can't possibly have forgotten the number of LTE-related issues that device was plagued with early on. I remember a buddy of mine returning his because as cool as 4G was, 10% battery drain an hour on LTE while sleeping was just plain unacceptable. The Bionic has had issues. Most likely ALL VZW LTE phones are going to initially have issues the way that LTE and CDMA are basically taped together with very non-sticky painters tape.
I've seen connectivity issues with my MiFi related to specific locations that I'm in (I'm a heavy traveler with work). Any "fix" will be purely for display purposes. The day that release hits will be the day I'll be on XDA trying to research how block the update notification. The GN is currently displaying true and accurate reception strength and I'm sure it's driving Verizon up the friggin wall.
Ok, I'll stop giving everyone a hard time. But really, if the device sucks in your area, I'd return it and wait for a fix. In all seriousness, as you now confirmed from flashing modems, no modem is gonna make THAT big of a difference overall. Constructively, I'd wipe the device, log in with my Google Account, install zero apps, and see what it does. If my battery life sucked, I'd take it to the Verizon store and ask for a new battery. If that battery sucked (like draining dead 3 hours in sleep mode) I'd take the device back and exchange it.
It's not that I'm calling you a liar, it's that typically that kind of behavior is faulty hardware. Having it twice in a row is abnormal. In all fairness, my first iPhone had a bad battery and died in 2 hours (permanently). My second iPhone would overheat and lock up. My third iPhone was "fine" other than the fact that it was an iPhone.
Did it leave a bad taste in my mouth? Yeah, sure, but I still accept the fact that it was a weird chain of events and that the vast majority are perfectly fine. What I'm saying, nicely, is that both your first and your second device are not normal. It's not Google's, Verizon's or Samsung's fault...well, Samsung's for putting together a few bad units, but you know what I mean.
Haven't said 2nd device has bad battery life, just 4g drops. Hoping battery life will be better on this one.

I definitely think something is wrong with battery life. I bought the extended battery and my phone is at 20% in 4 hours with screen brightness at zero and light texting and a lil fb. I feel like the regular battery lasted longer than the extended one I might test that next.

How to have great signal all the time

Our nexuses rule the roost. There is no question about it. The best android phone ive ever owned, and trust me, I've owned a lot of em
Just last week I got my extended battery for this phone and one of my two top complaints was resolved - the bad battery life. Now I pass by the entire day with enough juice left to standby the entire night.
My second problem with the nexus was that its signal reception got sloppy as soon as I hit the freeway. And many times it didn't seem to communicate with the network it was in correctly.
My factory is in the countryside. I spend most of my day there, but my radio isn't calibrated to do its best, and it affected my call quality, browsing etc.
Then I found this, and now the GN is the best device out there. Problem 2 solved. Its called "Network Signal Booster" by Brethrendm. I initially thought it was humbug, but I'm shocked where in my factory I used to get 1 or two bars, i now get full signal! and my browsing speeds are good too.
I want all of you to try it.
Thank me if it helps.
(Don't move this to application and themes, I'm not submitting an application here, just letting my experience with signal improvement be shared)
Are there any more tips to improve signal? I've seen by far KK6 radio works the best. With the extended battery the phone has also stopped heating, voltage issues I guess.
Sent from my Galaxy Nexus using XDA
by reading around it seems to only put airplane mode on and then off (u see the bar is beeing hidden for a while)..and that may resolve ur network problems sometimes
Hmm, only thing it did for me was kill the data/3G connection. It never put it back again, so the only way back was a reboot. A no go for me at least.
Maybe with samsungs low powered radios/chipsets will help with not getting Brain tumors

Mobile signal shuts off J7 (2018)

Preface: I did try the search function before posting, but my "search ninja" skills are a bit rusty. As such, if I overlooked an answer, I apologize for this superfluous post and would appreciate a link to the answer/other post. I also realize that it may just be that I am way behind the times with this issue and if that's the case, please be patient with me... I don't update my cellular tech as much as most people, usually only once every 4-5 years, lol.
So I got this new in box J7, got it set up and working, but I live in a dead zone. When I leave my house and drive to work where I do get signal normally, I just still have no signal. I have to reboot the phone in order to get my mobile connection back. I can only assume that this is a battery saving feature for when people are in areas of no signal for prolonged periods of time so as to not waste battery power searching for a network. If that's the case, it's a nice feature to have, but how does one easily re-establish a connection without having to power cycle? If a power cycle is the only option, I find this to be a major oversight on someone's part. Please tell me there is a setting somewhere I am just overlooking. Personally, I would love to have seen it not stop searching all together, but rather once you have been in a dead area for an extended period of time and activated the battery saving function, it would then only search once every 10 minutes or something. Maybe that's too much to ask of the developers.
