I actually experience the 3g/4g drop often on my galaxy nexus and I live in the bay area. Definitely sucks my battery to oblivion. Since HTC is said to make better radios I hope the drops would be less frequent.
[HTC Droid DNA] Cadillac Johnson:
I wouldn't worry about it, when I got the GNex I my thunderbolt up and running for a couple days and the radios are noticeably stronger and more stable on the Thunderbolt. Side by side I'd get solid 4g on the bolt where the GNex was spotty at best. My house isn't the in the strongest 4g area, but the Tbolt wouldn't drop off the signal no matter where in my home I was. The GNex I get 4g outside or by windows and that's it, with 3g speeds. The tbolt would pull a solid 12-15up 3-5down sitting right next to it.

Not to mention the GNex isn't exactly known for its radios.
[HTC Droid DNA] bsweetness:
The review doesn't talk about any drops in the traditional sense, but rather that the phone was "dropping back" to 3G in weak 4G areas:

This is something that is done on purpose in order to maintain a more reliable connection without as many actual drops when switching between 3G and 4G. With my Rezound, Galaxy Nexus, and RAZR MAXX, when I would be out on the edge of a 4G area, the phone would jump back and forth between 3G and 4G, resulting in actual drops in service and a drain on the battery. My S3 does what the DNA does - opts to stick with 3G in weak 4G areas. The result is a far more stable connection with less drops in service and much less battery drain.
[HTC Droid DNA] flaring afro:
Yeah, that's what I meant. Only dropping down from 4G. He said that you can't disable 4G though, but I'm guessing there will be a non-stock way of doing it.

I thought the pictures looked great, but I'm also comparing them to my 2.5 year old Incredible so pretty much any high end phone, besides maybe Motorolas, will look great to me lol
[HTC Droid DNA] hotmonkas:
man i really hope there will be a way you can disable 4G whenever you want. that'd be so useful if i needed to conserve battery and i'm in a spotty 4G area
[HTC Droid DNA] bsweetness:
Pretty much every LTE phone released on Verizon over the past several months hasn't had the option to disable LTE in the stock settings. Even some phones that used to have the option have had it removed in updates (such as the RAZR and RAZR MAXX). But with all of these phones, there have been ways of putting the phone into 3G only mode without root via an app or through settings that can be accessed through the phone's dialer.
[T-Mobile myTouch 4G Slide] sino8r:
After months of having this reoccurring issue myself, I FINALLY figured out a solution. It had gotten so bad on mine that wiping the rom won't matter... the only solution was to wait for several minutes/hours until it returned or switch to a Sense-based or a GB rom. This fix should appeal to those who had to return to older roms due this issue driving them insane!

Let's clear up a few things first.. to those having this issue and being able to restore data by going into airplane mode might wanna invest in a new sim card. Best to go into a retail location and pick one out yourself. The newest ones (model number TM9177 or higher) work the best and have the fewest data drop offs. That should fix a lot of users intermittent data issues from returning.

If you still have data issues and already have a newer model sim card (TM9177 or higher) OR have data issues that don't get fixed after a reboot, switching into airplane mode, wiping, normally have to wait a long time for it to return on its own, etc.... then this part will fix it. :highfive:

Go to home, menu, settings, wireless & networks, more, mobile networks, access point names, menu, and FINALLY add a new apn. Chose whatever for name of apn (maybe tmobile alternate, tmobile 2, or whatever), the next line, the actual apn, with be "wap.voicestream.com" (no quotes, duh;)). Next add this line to MMSC... "http://mms.msg.eng.t-mobile.com/mms/wapenc". Everything else should be left as is. Now hit menu, save apn. This new apn seems to work with all features I've tried... text messaging, full data access, same speed as default epc.tmobile.com apn, tethering, etc. Haven't tried MMS but the settings for that line is there in our alternate apn we just made. Please post results on that if anyone still uses that feature ;) So... that's it. The old apn works nicely and you say GO TO HELL! to the annoying data icon flashing on and off forever!

Be sure to post your results/experiences to confirm but it seems to be gone on 4 other MT4GS CM9/10 users besides my own. I REALLY HOPE y'all are as happy with this fix as much my family, friends, co workers, and I are! Do forget to use the thanks button ;)

Also... you can try "internet.voicestream.com" for an additional apn. I'm not sure if MMS will work on that one even with the MMCS set as "http://mms.msg.eng.t-mobile.com/mms/wapenc" but it's work a try. If anyone wants to check it out is welcome to. Again... post your results. I'm not sure how long tmobile will leave these old apns active but I bet it's longer than anyone will be still using this model lol! Enjoy! :p

Intermittent Data 3G 4G Loss Disconnect

Wow, Thanks. I've been fighting with this all day.

I've been running SilverL CM 10.1 for a couple of weeks and today suddenly lost my T-Mobile data connection.

I tried many solutions (I wish I'd found this thread sooner). Wiping Cache, Fix Permissions, Reflashed, different Kernals, different loads. Going back to Gingerbread worked, but I lost the data when I went back to ICS/JB.

There was even another thread that was close with deleting all APNs and creating a new one, but the settings still weren't there.

This took care of it right away.

THANKS !!!!

[T-Mobile myTouch 4G Slide] simpleagony:
thanks for the info! i ran across this thread while searching for a new ROM for my mytouch 4g slide, hoping it would fix the issue. once I arrived to the access point names, i noticed that the apn selected was for LTE. I switched to the regular one and now it works great. thanks!
[T-Mobile myTouch 4G Slide] mojoffdawal:
I had this issue while on cm9 releases but it had gone away after I began using unofficial 10.1. Sort of. In certain areas- and I assume with certain towers - my data wouldn't work with some apps (ie., Facebook, Google maps) even though the data icon would show "H" or "3g" locked on and blue consistently. Sure enough, this fixed it right up.

Also, although my phone shows the option for the Tmobile lte APN in the settings, it was not selected by default. Thanks for this!
[Galaxy S II Q&A, Help & Troubleshooting] Daimao1984:
Hello, guys. First of all, I'd like to apologize in advance for my bad english. If there is any part of the message that isn't very clear, please inform me so I can correct it.

Here's the deal: I've been using for some time the Jelly Bean Ressuction Remix Rom from Westcrip.

Since about a month and a half (since version 3.9, I believe), I've been getting some weird and random signal drops. Back then, I had to manually reboot my phone so the data connection would come back. At the time I thought it was because the rom was still a nightly build, not very stable, so I coped with it.

This problem has worsen considerably since one or two weeks ago: those "signal drops" have become more and more regular. And following the signal drop, the screen would flicker a little and then the phone would automatically turn off. When I turn the phone back on, the battery is almost depleted, even tho it was full right before the crash. Again I'd blame the RR from Westcrip (by the time I was using the version 3.1.0). When version 3.1.2 came out, I did a clean installation (wipe data/factory reset/format system partition/wipe cache and dalvik, etc), even changed the kernels (used both Dorimanx and Siyah), a lot of modems, and still got this same problem: signal drop (usually when the phone is under a relative amount of stress, like playing Angry Birds, browsing the web, and even while using whatsapp!!!) followed by the phone turning itself off.

I then thought: what the hell, the problem has to be with the rom, not my phone. Then, I tried installing different roms (Paranoid Android and Slim Bean), and still got the same results. If anything, the phone is rebooting even more often now than before. I can't use it for 15 straight minutes and I get that problem,

Since this has happened with all these different roms I dont believe its related specifically to any of those.

Another strange thing: this "signal drop" followed by the rebooting only happens when the phone is disconnected from any power source and being actively used by me. If I'm recharging it, for example, the phone wont reboot at all. Also, if it is over my desk but I'm not using it, the phone also wont reboot. However, if I take it out from the power source and starting using it, I'll get another reboot in about 5-10 minutes of use.

I searched the forum and didnt find anyone with a similar problem... have any of you guys seem this happen before? I'm beggining to think that my phone is gonna die on me anyday now.

Regards!!

Hi, thanks a lot fot the help.

I did all the steps above and I'm still getting the same results...

Another thing to notice is that yhe phone gets really hot for apparently no reason at all (like booting up, running aLogcat and other minor apps), and when that happens, I usually get a signal drop (if the phone is plugged in it wont reboot, if its not, it will reboot).

Is there anything else I can try?
[Galaxy S II Q&A, Help & Troubleshooting] Daimao1984:
Updating: I've been restoring my old nandroid backups for the whole day to see if the problem had anything to do with Jelly Bean. Well, I've gone back to the old ICS days and every version of it had the same random and constant rebooting. Even versions that didn't have any problem before.

I'm beggining to think I have a hardware failure of some sort. Do any of you guys know what could cause this kind of hardware failure? Since the phone has been getting hot for no apparent reason, it seems to me its a problem with the SGS2 cooler. Is that even possible?

I read that you can use ROM Manager to dual boot so I went to the Play Store to download it but it seems to be part of CWM? Or did I get that wrong?

I'm used to Amon Ra and don't want to switch off it. Can I dual boot?
[HTC Rezound] Flyhalf205:
ROM Manager doesn't play well with our device so shouldn't be used (CWM is apart of Rom Manager). There is an app out on the play store that lets you dual boot I think it's called Boot Manager
[HTC Rezound] famouscollin:
Even still I heard boot manager causes lots of problems on our phone as well, such as aosp to sense. The memory partitions are switches so when you try and boot thru boot manager itll give you a bootloop(cuz it reads the wrong partition).. I just know this from someone else's problem, I havent personally experienced it.. but if your using amonRa you can just make two seperate backups of the roms your wanting to use and restore your nandroid when you wanna change to the other.. this takes alil longer obviously but much safer and easier on your phone..
[HTC Rezound] prdog1:
Sounds like friend is not setup right because the boot manager app creates it's own partitions on and runs from the sd card. Have used it since it first came out and runs better than ever. Just waiting for them to complete port for S3 and will be rocking it again. :cool:
[HTC Rezound] GrayBoltWolf:
Boot manager works great on this phone. It is officially supported by the developer.

But you can't dual boot an AOSP and Sense ROM. Has to be two of the same.

I'm not sure how to recover pictures that you have already lost, but I would really recommend using a service like dropbox that has an auto saving feature for pictures. That way every image that your phone captures is automatically uploaded and they can be retrieved from anywhere. It's what I currently use for my GSII and it works flawlessly!

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] xshadowinxbc:
Hey guys. I rooted my AT&T S3 recently, using the guide on GalaxyS3Root.com. However, I'm still rather unsatisfied... namely because the performance--especially battery and wifi performance--of this phone isn't that good.

So, I've done some research about ROMs, but I think the best way to do this would be to simply ask more experienced Android users about their advice. Two main questions (I'll bold them in case you don't care about my explanation):

Does anyone know a ROM that has a better "WIFI radio", and has lower power consumption than the stock? Well, no, the battery life part is mostly a no-brainer, I guess, since I'm pretty sure other ROMs do. The main thing is Wifi.

Particularly, the way the WIFI is so unreliable on my campus (GA Tech) is quite annoying. While my iPhone 3GS would seamlessly transitioning to closer wireless hubs in a building, this thing waits until the one that's like half the building away is fully out of range (it stopped being able to use the signal from it a long time ago). Someone on another forum mentioned that some ROMs may use a better WIFI radio ("the software controlling your 3G/WiFi receiver chip"). That's why I'm interested. Unfortunately I don't see any of the ROMs outright stating this information...

Battery life... well, honestly I should probably weed out more bloatware, but I have heard certain ROMs do this better. So before I go picking out weeds, I figured I would ask.

If the answer to the first question is yes, then does anyone have any guides to recommend for getting a ROM up and running easily (ie minimal hassle) and properly (ie nothing left to chance)?

Sorry if this is wall-of-text-ish, and thank you for your assistance.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] c_86:
WiFi is controlled by the kernel. Try anew kernel first
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Heisenberg420:
WiFi is kernel level. Try ktoonsez kernel, it has the newest WiFi drivers from Samsung. Also has tons of options to tweak your phone to optimize performance and battery life. Also if your on the stock ROM I recommend you flash a jellybean ROM immediately lol
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] xshadowinxbc:
Thanks for the replies, guys. Is installing a new kernel any more difficult than installing a ROM? Any recommended how-to's?

Also, for that ktoonsez kernel:

Will it work on my 4.0.4 phone? Also, the only thing I found was a code repository. Is there a precompiled version of that kernel? I mean, I've done plenty of C/C++ compiling here and there, but I still kinda don't wanna mess anything up and end up bricking my phone.

Thanks
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Heisenberg420:
Download from this thread. Make sure you download the right one (tw ICS)

http://xdaforums.com/showthread.php?t=1756776

If you don't have a recovery installed download ROM manager from the market and install cwm.

Then follow the directions in that thread. General kernel flashing procedure is flash kernel, wipe cache & dalvik, fix permissions.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] xshadowinxbc:
Alright, I went ahead and did it. Installation went pretty smoothly (booting into CWM was the most trouble, just took a few tries..). The device is a bit warm right now, but it may be because I'm charging it. I hope this kernel doesn't eat my battery up more because of some random bugs. I do notice it has some clocking settings, though, which is really good. Namely, being able to set the maximum clock while the screen is off sounds like a pretty nifty power management thing.

Well, I'll be trying it out more over the next few hours.

Thanks a lot for your help.

Next issue:

As for improving battery life in general, does anyone have any app suggestions (app killers, bloatware to get rid of, etc). I already killed allshare (very happily I might add...). I think I saw a list somewhere on these forums, of bloatware it's safe to get rid of, but I'm not sure which particular apps have the most effect.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Heisenberg420:
Titanium backup is a good app for removing bloatware. Also check out this thread for tweaking the kernel to save battery life http://xdaforums.com/showthread.php?t=1886233
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] DarthDerron:
Kernel's have governors and I/O schedulers that you can tweak to get better battery life. As a start since you're on KT747, I suggest Ktoonservative and noop. You can look more into those on the KT thread.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] CamFlawless:
I agree with this suggestion. The largest increase in battery life happened when I changed my governor to conservative and i/o scheduler to noop.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] xshadowinxbc:
Hmmm.... well, that kernel didn't solve my wifi problem at all.

The battery life (when idle) went up by a tremendous amount, though, which is great. Android Kernel now hardly ever shows up in my battery monitoring app as one of the largest app drains, and that part is great. Opera seems to be a bit "heavy" on the battery lately, though... may just be Adfree.

I'm not actually sure what the wifi drivers solved. My wifi didn't really seem to perform too much different with them either way, and it certainly didn't improve the GS3's ability to keep a signal with multiple hubs around. I guess Apple is just that far ahead of Samsung when it comes to both their wifi drivers and their wifi hardware (which is sad, because I'm comparing a GS3 to a 3GS). Sigh. At least I'm graduating this semester anyway.

Does anyone have a different suggestion?

Again, thanks for all the help.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] jethro650:
In the advanced wifi settings there is an option to ignore weak wifi signals you could try that although I havent had much luck with it, I have three wifi routers in my house to cover the whole house. Also see the below link to deal with tbe bloatware.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Heisenberg420:
Exactly what problem are you having with WiFi? I believe once your phone connects to a router, it stays connected until you disable it or go out of range. I've never heard of any type of computer that keeps scanning for better signals. This would just waste battery life. There may be a 3rd party app out there to do this but I wouldn't be interested in that.

As far as improving reception, there's no software upgrade you can do to improve WiFi reception. I think the only benefit new drivers have is faster to establish connection time. Some cases (including my speck candy shell) ive noticed have interfered with signal strength slightly.
