LTE Galaxy Nexus Boot Loop after dropping WiFi connection. - Samsung Galaxy Nexus

Hi. Every time I leave my house and therefore lose WiFi, my LTE G'nex reboots and gets stuck in a bootloop. There's no way for me to fix it except to restore a backup or to get within range of my WiFi.
Is there any way to fix this (other than turning off my WiFi before I leave the house) or do I need to call Verizon for a replacement?

I've had this happen twice. I didn't realize that was the cause until I searched this morning for it. After the 1st time, I had Verizon replace it. 2nd time I did a factory reset. I haven't turned Wi-Fi back on to try what some people are saying that when you go back into the Access Point area that it stops looping...don't really want to try that since I don't want to chance wiping my phone again since I've yet to root and don't have a backup. If you search "galaxy nexus boot loop issue" in Google, there's a link to a Verizon thread that talks about it, and in there another link to an Android forums thread as well. Can't post the links because XDA won't let me.

[Q] 3g connection will not stay up

So for the past 2 weeks I am having issues that basically render my phone unusable for 99% of the reasons I bought it. Posted a thread before but I think it got lost when the forums were having some instability around that time...
My 3g connection will NOT stay up. I did nothing to provoke this. No system changes. The sequence of events:
-Went out of the country with my phone on airplane mode the whole time
-Got back, a day or two later had an incorrect timestamp on my incoming SMS (they were showing up +3 hours)
-Called customer service, she activated a tester phone and confirmed that it was a system-side issue on the incoming SMS (somehow they were getting a timestamp from the system where my number is located, in Eastern time, while I am actually located in Pacific nowadays).
-Put in a trouble ticket after 2 hours trying to solve the SMS issue over the phone.
-Next day, my 3g connection begins dropping CONSTANTLY. As it stands, it won't stay connected more than 30 seconds. It will cycle to 1x sometimes, and then drop to a basic-service-only.
-Tried reinstalling my ROM several times to no effect.
-Started experiencing some very strange noises in SOME calls, such as it sounding like a chainsaw when the other person is talking. Happens very sporadically.
-Just today I found some instructions here for correcting my NAM settings, which were actually messed up as it turns out, but didn't fix anything.
At this point I actually have the phone unrooted and back to factory default everything, with no change. I've got a warranty replacement phone coming in shortly, but I'd still rather keep this one if I'm able to.
Is there anything I haven't tried that might be the case on my end? Has anyone seen this problem before? Has my phone antenna simply gone belly-up, or is this something that might still be fixed at some deep system-setting level, or with further calls to tech support?
So... I guess that's a no?

Had the same problem with my phone before I rooted my phone and starting to apply ROM's. I havent had a problem since. But when I had that problem, I would just keep turning on and off the 3g and it would stay for a while. It was just a quick fix but it worked. Off subject how did you unroot your phone and put it back top stock?
My phone just started doing this this yesterday. Whenever I reboot it, it'll come up, switch to 1x mode. After a while it'll try to switch to 3g mode, fail, switch to no service, and then either go to just basic voice with no data or back into 1x mode. I've tried updating the radio, switching roms, dialing *228, nothing seems to help.
Jager, instructions on a full reset are right here under section 6. I'm not sure why it's struck out. Definitely suggest poking around more first.
New phone's in and still having major connectivity issues. The SMS timestamp remains as it was, and I can't get (steadily) more than like 35kbps. I'll occasionally bump to 500kbps for a quick spurt, and then my connection will drop entirely and struggle to get back up to 35kbps. My wife's Incredible works perfectly fine in the exact same locations, too, so this is something that absolutely has to be on Verizon's side, specific to my line.
Me too
My phone has also been experiencing the loss of 3G service as well. I checked my wife's Moto Droid 1 and it was also having difficulty connecting as well. I called Verizon and they were absolutely no help whatsoever. I am either getting nothing or 1X in places where I have always had 3G. This is very frustrating. I have flashed 3 different ROMs (all of which have worked fine in the past), but the result always seems to be the same. Anyone else out there with this issue?

Someone help! Same issue! I can no longer get data....PERIOD. I have to stay connected to wifi, or I don't get my emails, internet, etc.
Need to fix this!
3G connection issues
I just got off the phone with Verizon Tech support. They are CONVINCED that it is an issue with my phone (and my wife's). Gee, how can 2 different phones, from different manufacturers have the SAME issue at the SAME time? Hmm, doesn't sound very promising to me.
They are sending out a replacement for my wife's Moto Droid to see if it is a phone issue (she has been having other issues with it anyway...). If hers improves, I may send mine back, but I don't want to have to unroot, etc. Plus I like the Super-Amoled screen . When did trouble-shooting turn to "replace the hardware first" ???
Regards!
This happened to me recently as well and was fixed with a factory reset.
I am rooted with S-off, so a normal factory reset via Menu->Settings->SD & Phone Storage-> Factory Data Reset didn't go well for me. Not sure of the exact reason, but I just followed the instructions in this post to restore: http://forum.xda-developers.com/showthread.php?t=786436
Programming your phone by dialing *228 is necessary afterwards as well, as khukman states below. Thanks for pointing that out.
After I completed this, I redid root, restored my nandroid backup and didn't lose a thing, plus my 3G is working again!
*A fair warning: Doing this formats the internal storage (emmc). I'd recommend backing up any photos, music, etc that you have stored on emmc before doing this!

So I tried the above suggestion about going back to completely stock 2.2 and I have the same results. On one hand, I am now back to S-ON and stock Froyo, so if I want to send it back to Verizon, they are none the wiser that I was rooted, but on the other hand I STILL HAVE CRAPPY 3G SERVICE!!! Man, I feel like I'm on AT&T or something LOL! I'll keep an eye on it for the rest of the day and see how it does and report back.
Back in 3G!!!!!
After getting back to stock Froyo, as described in the previous post, I was still unable to get a good 3G lock. I read in another thread where someone did a 'Factory Data Reset' and it took care of it. When you do this, you have to dial #228 and let it program your phone as it did the first time when you got it. Once I did this, I had (and still have) a solid lock on 3G like I used to. I think that it was one of the Sprint ROMs that screwed this up in the first place (the OP states that you have to backup your PRLs, etc. before installing, then re-install them afterwards). I can't remember if I did this or not, so it may be my fault after all, but regardless, I am thrilled that once again I have a connected smartphone thanks to the resources contained on XDA!
Regards!
I myself am now rocking a refurb that has no trouble at all... A complete revert to stock did absolutely nothing to resolve my trouble.
Though I didn't try doing a factory reset AFTER reinstalling the stock ROM. Hmm. Maybe there was something in the cache still. I suppose in my case I'll never really know, but I'm glad you guys were able to resolve the situation with your original hardware.

Did you follow the steps in the thread I posted above? Doing that should completely format and re-image your phone. Much more than just installing a stock ROM. I myself tried so many different variations of ROMs, radios, etc and nothing did the trick until I followed that thread.

[Q] Wifi loses connectivity after period of inactivity

Hello,
I've searched around the Epic 4G Touch forums as best I could, but sadly I couldn't find anything that was exactly this problem (although I found some interesting articles about wifi sleep time but they don't seem to apply). I'm experiencing an annoying issue where I can connect Wifi just fine, but if the phone is left for a small period of time (~10 minutes), wifi appears as if it's still connected, however it cannot send/receive data. When this happens, the wifi status says it's "connected", but there is no data connection. The only way to to get the data back is to turn off wifi, wait for 3/4G connection to initialize, then turn Wifi back on to refresh it...then it's fine again until I set the phone down again.
I had this problem on stock EL29, so I rooted and flashed Phantom Blazer ROM (very cool ROM, but I'm still experiencing the same issue). After reading the threads on here about wifi sleep times (apparently they're backwards with ICS roms), I've experimented with every setting, yet I still have the same issue--Wifi is fine as long as I'm using the phone, I set it down, after about 10 minutes pick it back up, says it's still connected, but no data connection.
has anybody experienced this problem with this phone? I'm about to unroot my phone/go back to factory so I can take it in to a Sprint store, the problem is they (trying not to be offensive) don't seem to know very much about this device. I thought I'd ask the pros before I return it, get an iPhone, and have to eat my words about how cool Android is vs. iPhone in front of all my friends. I'm hoping there's a reliable ROM or app that can resolve this vs. having to just replace the device!
Thanks for your help!
I'm not the only one
I'm not the only one with this problem:
edit: I can't post links to androidforums.com or anywhere else, but this same problem is all over the interwebs and nobody has a solution.
I'm sure it's not my router as my ASUS tablet/laptops/girlfriend's iPhone experiences no connectivity problems. I'm thinking this is a hardware problem with some of these devices. I will unroot/reset to factory tonight and let you know what happens.
What channel is your router on? And what type is it A/B/G/N?
This is s known TW ICS bug, most likely kernel related. Almost everyone is having this issue and there is no fix until Samsung decides to repair it. There are quite a few posts similar to this one. If you're using XDA's search function, it's not very good. Try using Google next time and search XDA that way.

Hey guys, thanks for the response. Just before I unrooted/reset to factory I tried one last solution--download an app called "Wifi Fixer". It has resolved a lot of these problems. It's not 100%, but after testing it for a day so far, I've only had to manually refresh the connection once or twice. It's a lot better, even liveable, and I won't be resetting to factory afterall, at least not until Samsung provides an update. So if anyone is having the same problem, try Wifi Fixer, hopefully it gives you a similar level of success...I'm not super happy about having to run another background process all the time, but it doesn't seem to affect battery, and the fix it provides is worth it to me.
Cheers!
Huh - a couple of things. Noticed this problem crept back in FF18 and didn't know why until I went back and checked the wpa_supplicant.conf that I'm using. The line ap_scan=2 was missing; after adding it back in the signal strength is back to full and stable.
I'll bump the thread but it appears the config changes here still hold after all:
http://forum.xda-developers.com/showthread.php?t=1569348
This should also avoid having the WiFi fixer there as you can specify the country in wpa_supplicant.conf manually.
Thanks for looking in to this! A couple questions from a noob like me though:
When you say the problem crept back in FF18 ... what does that mean? Is that something that exists in the "stock" version of the Epic 4G touch from Sprint?
The manual config file tweaks you're describing ... is that something I can perform myself?
Basically I'm wondering if it's "safe" to revert to stock in order to get consistent wifi signal, or if it's something I'm experiencing because of the ROM I'm using.
Thanks!

[Q] need to reboot or toggle airplane mode to regain connection

Hello,
I am running into an issue where I will lose connection after coming off wifi and it seems 4G/3G is not picking up. I must either reboot my phone or toggle airplane mode to regain signal. I've been searching around and I don't think I've found any thread similar...or it's hard for me to pin one down using search terms.
I'm running paranoid 2.16 and lean kernel. Gonna try and flash a radio and see if that helps...but if anybody can point me in the right direction or suggest a few things, I would greatly appreciate it.
Thanks in advance!
Lte or gsm version? Apparently the lte version has reception issues in general.
I used to take the subway to work. When coming out of the train, after losing service while underground, I would on rare occasion have no service while above ground in an area where coverage existed.
This bug existed on every Samsung smartphone I've ever owned (sch-r720 admire, t989 Hercules, and yes the i9250). I'm convinced it must be an android bug.

I'm stock (rooted)/GSM and I'm having this issue since 4.1.2. 4.1.1 was very stable for me. Today it lost it's connection completely to T-Mobile twice, where the status was always connecting even though I had 3 or 4 bars. Additionally, airplane mode would not engage (no symbol in menu) and could not be unselected from the power menu. Only way to fix it for me was to reboot the phone.
Additionally, I received a call today and the phone froze. I could interact with it barely, but couldn't switch apps or get out of the completely black phone screen. I had to unlock the phone to even see anything. After I missed the call, which rang for a long time (still no idea who it was - no logs and T-Mobile only lists connected calls), the screen would not come back on and I had to do a battery pull.
I'm about ready to just say F*** it and reinstall 4.1.1 stock back on this thing. I want my old phone back
Additional notes: The phone is encrypted due to my job requirements.
If restoring your backup cures the issues, then its baseband/radio/rom related. If not, the phone is damaged.
I had an sgs2 t989 which one day decided to lose its data connection. It constantly tried to sync and couldn't. Voice and text worked, but it couldn't get data (even edge). Changing roms didnt fix the issue and I had to exchange it in store.

WiFi on the G3 headaches [SOLVED]

I just got an LG G3 last friday (Black Friday) on T-Mobile (got tired of Sprint). Anyway for the most part this phone has been great. A minor glitch with a game (possibly from porting it's data over from my S3). The main problem I have is with the WiFi.
First off WiFi calling sucks. If I don't have 3 or more bars on my WiFi connection the call gets fuzzy. During one call that was clear it just randomly dropped. So that isn't cool.
Secondly, if I connect to a WiFi network at home or work or where-ever and then go somewhere else and come back or go to another place with a network I want to connect to it won't connect at all. It will show all the networks and give me the option to connect. But instead of connecting it will try to connect for a long while and then just give up. I cannot get connected again until I reboot.
I have tried the suggestions found on this thread (and other places): http://forum.xda-developers.com/lg-g3/help/lg-g3-wifi-issues-t2829811
No luck with those suggestions. Which include the following:
Turn off and back on the wifi radio.
Disabling the "wifi signal is weak" option.
Disabling the battery saving for wifi.
Forgetting the network (my network list was automatically imported from my Google account).
Installing the "WiFi Manager" app and enabling the 5GHz channels (US) and changing 2.4GHz channels to "Complete".
Made sure that "Internet unavailable" option is disabled.
Made sure that "Keep Wi-Fi on when screen is off" is set to "Yes".
Disabling NFC.
Disabling BlueTooth.
Disabling Wi-Fi calling.
I don't have problems with a weak signal. So I am perplexed. My Samsung Galaxy S3 worked just fine on these networks. Restarting always seems to allow me to connect again. But I shouldn't have to restart every time I want to connect to WiFi.
All of my other wireless devices connect just fine in the household (a PS3, my fiance's Moto X, my old S3, MacBook Pro, Lenovo Windows 8 laptop, an HP running Ubuntu 14.10, and another Lenovo running Ubuntu 13.04).
Why is an older model phone doing so much better than the G3? Both phones are rooted (old and new). Does anyone have a fix? My phone is currently running LG's factory rom "D85110m". That is with Android 4.4.2 (my old S3 is on a cyanogen rom of the 4.4.x series as well).
Please help me fix this. Otherwise I might return it for an S5.
Thanks!
**** Update ****
Per my below post, it seems I have fixed my problem. I ended up doing two factory resets, unrooted, and did a final factory reset to fix the problem. Then I switched to the PurpleDrake method to root it the second time (and it worked really well without any issues).
Good luck everyone!
**** End of Update ****
Try to factory reset the phone. I don't know what version you are on but I assume its 10m

It is on 10m. Do I need to unroot before I do the factory reset? I have never had to do one before.
So it appears that doing a factory reset does not fix it. I guess I am taking it back and having them replace it. And I will demand it be a brand new one since I just got this phone a little over a week ago.
SOLVED!!!!
Ok, so I finally got it fixed. Albeit accidentally as I didn't expect it to be fixed at this point.
Here is what I ended up doing:
Two factory resets.
Unrooted the phone (via these instructions: http://www.androidrootz.com/2014/07/how-to-unroot-lg-g3-all-variants.html).
One last factory reset at T-Mobile store by me (because they forced me to).
The wifi did not start working correctly again until after that very last factory reset that I did. The unroot process also does a factory reset. But, and this may be key, it downgraded my phone to 10c from 10m in the process. I then did an OTA to 10m after the final reset.
I unrooted it because T-Mobile's diag software detected it was rooted and said that made the warranty invalid. And after I unrooted it I took the phone back to the store and demonstrated the problem to the employee that sold me the phone in the first place. He tested it for about 10 minutes and came to the same conclusion as myself. He then had to go to his manager to approve the replacement.
They got out the new phone to replace it with then the manage told me that he was required to have us to one more factory reset. So I went into the settings on the phone and did one last reset. And for some reason, since this point, the wifi problem has gone away.
I think it is possible that something I did to the phone caused the problem in the first place. But since I did so much to it in the first few days (rooted and installed a ton of apps) I am not entirely sure. My two current theories are it was either caused by this malware infected flashlight app I installed that kept popping up the Play Store to install a particular app. Or it was caused by the rooting method I used.
The original rooting method I used was "Stump Root". So the second time around I used the PurpleDrake method. This is a tiny bit more tedious, but very effective and it didn't seem to break anything. Further, when I installed TWRP I made sure that I grabbed the recommended image for it that is specifically for the US T-Mobile LG G3 device and installed that using Flashify.
After I got it safely rooted I tested the crud out of it and it seems to be working fine.
One last thought. It is possible that somehow Titanium backup caused the problem when I restored text and call logs. But I seriously doubt it.
Anyway, if anyone has any questions for me about this please shoot me a message. I am more than happy to help.
Thanks,
Patrick

[Q] Mobile DATA keeps turning on Automatically

Every since Verizon pushed the Lollipop update to my N4, my "Mobile Data" turns back on all by itself after it has been disabled. It even turns back on when I am connected to wifi.
Has anyone else experienced this and if so can you please explain how I may fix this.
Thanks in advance.
Not exactly that but I have noticed that now I'm always on 3g when I'm usually on 4G all day long same area this is crazy
Mine is also randomly turning on Mobile Data too after the Lollipop update. I have a small data allotment with VZW, this could send me into overages.
I seen on one thread, searching through your downloaded apps to find out which ones have "change network connectivity" in the permissions. I happen to have 6 of them. Some you can disable, but it removes the updates, other you cant disable without removing it.
Another recommendation was hitting settings from the pull down menu, wifi, advanced, then uncheck the "smart network switch". Mine wasn't checked to begin with, so I'm out of ideas til I start removing apps one by one...
The data has been turning on by itself during sleep time on my Note 4. It caused the phone to use 500mb of data in one nite. My data is always off, wifi is only on when using the phone otherwise it's off too. I called Verizon and they have no clue. This is my 2nd new Note 4 for myself & my wife, nothing but problems. Think we are going to switch to anything other than a Samsung phone.
Well, I've systematically removed all 6 apps one at a time. The Youtube and Facebook apps, I was only able to disable them instead of removing them completely. In the end, the phone still turns on Mobile Data by itself. This must be something internal with Lollipop. I have a small data allowance and I'm afraid its going to go over simply because it wont stay OFF even with WiFi available!!
I would call customer service and have them ship you out a replacement. This is our 3rd phone and hopefully it will work as it should. Good luck
Outcast,
I've had my Note4 since it was released in November. It didn't have this problem with 4.4 Kitkat. It's something new with Lollipop and I doubt a new phone would solve this problem, could be wrong.
How involved is it to go back to Kitkat?
I'm not chancing voiding my warranty. They replaced my phones by them and not by request. Our phones get hot and get a warning then shuts down, apps close constantly and the phones consistently reboot on their own. Then the data turning on by itself. The other problems I don't think are software based but hardware failures. The data can very well be software related.

I have the same problem and i used up so much of my data when i am at home where the wifi connects automatically on everything else. On kit kat this never happened and i am attempting a downgrade so you might want to try that.
I was having the same problem with mine. I also live on the edge of 4g area, so it was constantly swapping between 3g and 4g. In addition to using some data it was killing my battery swapping between 3g and 4g. Using almost 10% per hour when not being used. I disabled most of the verizon stuff, support and protection, Verizon navigator, caller name id, message+, and verizon location. I turned off facebook location reporting in the app settings, and disabled google location. I did all these a couple at a time and would reboot to see if it fixed the problem and after all those were done i rebooted and wiped the cache and the prblem was gone. I turned google location back on so far and its still working the way it is supposed to. It shows a greyed out 3g symbol and my battery life is much better. My phone sat off the charger all night and only dropped 4% and in 5 hours of moderate use its down to 77% left. Wish i knew exactly which app was causing the problem to help you out better but hopefully you can try those apps and settings and get the same results.
Well it worked for about 3 days, but this morning data and wifi were both running again.
Data usage Samsung Galaxy Note 4
Been having the same problem even when I disconnect data ten or fifteen minutes later data is back on. And I've noticed even if I am connected to Wi-Fi data trumps it and I end up using a ton of DATA when I've been connected to Wi-Fi all day, getting seriously upset cause I never used this much data before.
I have same problem with my Note3 running Lollipop. Have tried every suggestion I can find to turn off data, but it is still runs, unless I am on wifi. Data is set to off, 4g symbol in notification bar is greyed out, but data is still on. I have found forums all over the Web with other people with this problem, but no solution yet. My phone is unlocked but not rooted.
