LTE intermittently turns off, restarting phone is the only fix - Nexus 6P Q&A, Help & Troubleshooting

Hi all, I've been having this issue for the better part of 2 years and still have not found any threads discussing it or any potential fixes. I've tried most of what I could do to try and fix it but to no avail.
My LTE "turns off" at various points during the day while I'm using it. For example, I'll be scrolling through Facebook and then my LTE just shuts off. Data intensive tasks aren't the reason either. I've noticed it has turned off while streaming, browsing social media, or even just using my phone. Some days the LTE turns off more times than other days. Turning airplane mode on and off does nothing. The only temporary fix I've found it to restart my phone. On bad days the data will turn back off within minutes.
I've tried factory resetting my phone, but after 3 attempts I'm not gonna do that again. I even tried getting a new sim card and 2 attempts did nothing. I've also tried changing to every setting you can find under network or mobile data. Nothing has fixed this damn issue and it's honestly more aggravating than my phone dying at 50%, with its 2nd battery.

phone rebooting / locking in standby

Over the last two days my phone is rebooting repeatedly upto 20 times in a row before booting correctly (keeps halting on initial td2 boot screen). Also the phone is locking in standby mode, and will not re-activate until i take the battery out. One other issue I have seen is an error message "the charging current is not enough for device power consumption. Please shut down unused applications or switch to AC power" - when the phone is charging. Has anyone else had any of these issues, or know whats wrong or if it is fixable. Any help would be appreciated!
Thanks.
I had the same problems with the TD2 that a had to remove the battery and restart the device because it wouldn't get out of stand-by or maybe the device went off and i couldn't get in on until the battery was removed and replaced.
Also i had problems that my device automaticly goed out of standby in standby en asking if i want to turn the device off. Already did 4 hard resets. Nothing seems really solved the problem.
Already send the device to HTC with all these problems, and guess i get it back with same problems.
Now my device is working great. A did a hard reset and after installing a program i reboot my device. It may sounds a little stupid but it works for me. Also i installed framework 3.5 on the device now and not on the memory card
sorry about my bad english
I had this problem on the Tytn II when I first got it, and I have only had my Touch Diamond 2 for 4 days and I have had the same problem.
Its called the Standby of Death or SOD by those in the know, the phone fails to respond to a power button press and come out of standby.
I found a workaround for the Tytn II which was soft resetting it everyday, then found a better solution by not running the owner ident screen, disabling 3G and making sure no data connections were active in standby.
On my Touch Diamond 2 I've not been running the owner ident screen but have had 3G enabled over the last few days so my guess is its something to do with that, I have now disabled 3G and hopefully this solves the problem and I will have much better battery life too.
I've tried hard resetting and re-flashing different roms - it makes no difference. Also now noticing today severe battery drain, even when the phone appears to be locked up - battery has gone in around 3 hours. No idea if it is a battery issue, or hardware in the phone though
I had the Standby of Death SOD this is when the phone fails to come out of standby with a power button press. This issue only affects some people on some networks. I'm not sure if its a network problem or a software problem but as only a minority of people have it, I suspect its mainly a network problem there is a software solution.
The solution is to change the phone settings band option from auto 3G/2G to either 3G Only (WCDMA + UTMS 2100 in Europe) or 2G Only (GSM + AUTO) depending on your requirements.
EDIT: Also read this thread http://forum.xda-developers.com/showthread.php?t=540943&highlight=standby&page=2 where the resolution was to get a new SIM.
I hit problem when reboot the device, it stuck in the green WM startup screen.
Nothing can do, except keep trying press the reset button....very trouble to remove the back cover.
I am suddenly having the "charging current is not enough for device power consumption" issue. It started tonight. I've had the phone 1.5 weeks, and am on my 3rd ROM...have had it running for a few days without this issue. I haven't really been having any issue with SoD...but I have been having SMS issues (after an indeterminate amount of time, I unknowingly lose the ability to send/receive SMS until I SReset).
Could this be SIM related? I don't store anything on the SIM...but it has been in 3 devices over the last 15 months. I have a brand new one here. I'm going to call ATT tomorrow and switch to the new SIM and see if that resolves anything.

Temperamental...

My G1 has recently started playing up. The problems first started with cyanogen 4.1.9999 - it would loose signal, but a reboot sorted this out and it may only happen once every two or three days if that. It was an unstable ROM, no biggy.
But then one day, after rebooting, it got stuck at the android screen then just turned itself off. This repeated several times before it just wouldn't turn on. I left it for a while and tried again later, it turns on, boots but no signal. Rebooting did nothing.
I reflashed (without wiping) cyanogen 4.1.999. and everything seems okay. But then the phone started crashing and rebooting rather a lot, and rather unpredictably. So I wiped, flashed the ADP rom and then cyanogen 4.2.1 rom. This process was a massive brainache - plugging in the usb cable managed to crash the phone within 2-5 min guaranteed, it automatically rebooted.
So here I am. Cyanogen 4.2.1 - after a complete sdcard format, wipe, ext3 repair and flash. The problems still persist! But it's temperamental, a lot of the time I loose signal still, it often reboots itself and hates anything plugged in the usb when it's turned on - making charging the thing awkward.
I used the log collector app to get these logs
http://nopaste.info/17b5351296.html
http://nopaste.info/2e98b9d044.html
At some point during those logs, the signal is lost. The log collector doesn't seem to retrieve a very long backlist, these were taken minutes apart but don't overlap, so I haven't caught a crash. I'm not sure if there are better ways to view logs/debug?
But it's all very temperamental. Occasionally it boots up and life is fine. But more often than not it will loose signal and reboot itself somewhere along the line.
Has anyone come across anything like this before? When it looses reception if I manually try an connect to a network it will say
"This SIM does not allow a connection to that network"

I've read that could perhaps be a problem with the sim... but the sim wouldn't cause reboots would it?
Any advise would be great. I bought the G1 off ebay just under a year ago, so no warranty.

MAJOR problem - phone restarting every 10 seconds!

Hi guys,
this is my first time using these forums and I wouldn't have done that if the problem was easily solvable. However, this is a major problem for me and I couldn't find a thread nor a solution to it, so I'll post it here.
I have the i9305 4G version of the S3. I have had it for about a month now, and it worked fine, up until now. The phone suddenly starts to restart itself (not reboot!) for about 10 seconds, then goes back to the dashboard.
The problem seems to be the WiFi. Right after I get the "Connected to ... network" message on the bottom of the screen, the phone vibrates immensely once, then everything freezes for a few seconds, then another 2-3 vibrations, before the Samsung logo comes up with the LED light on. After a few seconds again I'm back in the dashboard until I get the "Connected to ..." message, and so on the process repeats itself.
Turning off WiFi seems to solve the issue, but once I turn it on again the problem reoccurs.
Something else I've noticed is that if I have WiFi turned off and cellular data network (for instance 4G) turned on, the "4G", "H+" etc. logo does not appear, even though I'm connected to cellular data! Don't know if it can be related to my main problem.
I have tried everything I'm aware of. Unplugging the battery, factory reset and back up, hard reset, wipe cache pertition. After the factory reset I can use WiFi again, but only for a few hours until the problem reoccured. I THINK once my battery is fully charged the problem occurs.
Note: I haven't even touched stock ROM, kernel etc. Nothing is flashed. Phone is in the same condition as when it came out of the box. Android version: JB 4.1.1
I would be forever grateful if you could help me out here, I can't have a phone restarting itself and vibrating like crazy every 10-15 seconds.
(Sorry in advance if this was the wrong place for this thread.)

UPDATE:
Seems like my issue isn't just related to Wifi. Cellular data network was actually related to my issue, as I first feared. If Wifi is turned off and cellular data turned on, the same thing happens. Seems like the issue occurs every time I try to use the internet either way.
Anyhow, if I let the phone reboot itself without turning on or off anything at all, it will reboot about 5 times until either Wifi or cellular doesn't work anymore even though the status bar tells me that it is turned on!
This seems to be a serious connectivity issue and for the first time I'm suspecting interference with the phone's wireless network hardware. If none of you are able to provider an answer, I guess I have no choice but to hand it in to get it repaired or replaced.
Still noone who has a solution to my problem?

My solution to your problem would be to just bring it to whoever you bought it from and demand a replacement. That isn't normal behaviour.
you can boot into recovery and do a factory reset and cache wipe
if wiping does not solve your problem, just return your phone.
I don't know if this is related, but, I had this issue once (the cause is not wifi though), and samsung fixed (or replaced) my phone.

I'd wipe the phone and return it. This is not normal behaviour and should fall under warranty... Wiping might fix but this may happen again if there is an inherent problem with your handset....

Phone Randomly Keeps Rebooting YMMV fix

This may or may not be related to anybody having the same issues but I'd like to report on a fix for this. This may or may not apply to you so YMMV, but this defenitely stopped my phone from rebooting randomly.
The thing that fixed my phone from auto rebooting by itself randomly is to go into your Play Store option and set Auto Update Apps to 'Update over Wifi only'. I had set it to never update. I can't get into why it happens since I don't know where to check logs but this does work for me. (Menu>Settings>Auto-update apps)
My story: Yesterday my phone reboots by itself every few minutes without even touching it for no reason at all. Phone had about 75% juice. I remember doing the unlock and had no problem with it for the whole day. I was at jury duty, boored and I was messing with options to restrict background data and changed the Play Store update options to Never Auto Update Apps since I switched to Tmobile and I don't have an unlimited data anymore. Afterwards the phone started rebooting by itself at various times during the day. I didn't notice until later on the night where it rebooted itself every few minutes. So I tried out various fixes which didn't work and set Airplane mode stopped the rebooting but wasnt a fix. After awhile I tried to retrace all the stuff I did on my phone during the day and strangely setting the option back to Auto Update Apps to Wifi Only fixed it. After doing that the phone stopped rebooting by itself and I was able to use it all day today.
So basically, see if setting the auto update to wifi only if you had it off will fix this.
Also I realize there are many different fixes other users have reported like the Power Cycling, Airplane mode or Clearing Dalvik and Cache(Which didn't work for me), or even reflashing/reset to factory (I avoided this). None of those worked for me. If those didn't work for you, try this as another option.
Mods: Please move this to Sprint Samsung S4 section. I have no idea why I'm in this section. I'm sure this applies to every S4 though.

[Q] Galaxy Note 3 Wifi stuck on "activating"

Hi guys,
I own a Galaxy Note 3 and in these last months the Wifi connection has been acting strangely, at first the Wifi would deactivate itself and I needed to reactivate it everytime, then it started to not activate normally, it would remain stuck on "Activating" in the settings options. At this moment I can't even turn the WiFi on anymore in any way.
Here a list of the things I already tried:
Reboot the phone
Take out the battery for a couple of minutes and rebooting
Turning off "WiFi Power Save Mode" via the dialer *#0011#
And at last factory reset. (When I reset it the first time the wifi seemed to work again but after some updates and a reboot the wifi won't turn on anymore)
P.S: No carriers and never rooted
A friend of mine had this issue with GS2. He went for a replacement finally.
I see the same on my N9002. I consider this a hardware issue. It started with occasional WiFi shut down. I was able to restore WiFi after opening the device playing around with the connectors or removing the screws. The outages became more frequent. Now WiFi and Bluetooth are both dead.
I did everything software to fix it. Several resets, several different ROMs, updates - with no effect.
I am on the way to a repair store now to see what they come up with.
