Random Reboots on KitKat (AT&T) - G2 Q&A, Help & Troubleshooting

I'm running stock, rooted kitkat with stock recovery, flashed on brand new phone, that I also wiped after flashing. I'm getting several random reboots daily, usually when I get ahead of the phone (swiping too fast, hitting home several times because its not responding). Was this the case on JB? Is anyone else having this issue or can they test by opening apps quickly and see if it locks up?
I have 4 G2's in the house, all on the same software. Mine does it most often but wife's has done it a couple of times as well. Just curious if I should attempt a replacement or downgrade to JB to fix.

Phone is freezing since JI6

I updated my phone manually through Mini Kies.
Before the update with or without OCLF applied, the phone would never freeze. Since I've applied the update the day before yesterday, the phone has locked up three times. Basically what happens is, the screen will, well, freeze, and my button presses do absolutely nothing, I hit the back button- phone vibrates, does nothing, same with home button. To power it off I either hold the power button for 5-10 seconds, I have not yet had to pull the battery. HOWEVER. This last time it froze, I powered down the device but the phone would not turn back on. I pulled the battery from the phone and inserted it back in and after doing so my phone powered back on with no problem. It's a bit concerning though. Probably the worst thing about all of this is the fact that my phone runs great! Fast and responsive, GPS seems to be spot on. Except about once a day since the update, it freezes.
Any ideas? I have no experience with modding/flashing anything so I get really nervous with things like installing custom roms. I was thinking I could roll back the update and then re-do the update. I doubt I'd get the update OTA though, I updated my girls device OTA and she has had no problems so far.
I was even considering flashing Bionix, but again, very nervous to do so. I even had trouble just creating a nandroid backup! I couldn't get into clockwork recovery to do so.
Can anyone just baby me with this? Tell me where to start?
Thanks :/
I would suggest you flash back to stock firmware using Odin.
Go into the Development section and look at the directory sticky. There is a link in there for a thread on how to go back to stock firmware.
Once you flashed back to stock, i suggest using it on stock for a day or two to make sure the phone work correctly. Once you verified the phone working then try to update to JI6 again via Kies mini.
Other than that you can start to mess around with flashing different custom firmware and mods. It hard to brick the phone since you can always go into download mode and odin back to stock.
Be adventurous! Good luck!
would you suggest that I go back to stock before trying to flash bionix?

You should go to JFD then to JI6. Freezing isn't normal, I don't have any freezing. If it was randomly freezing there would have been a 10 page thread on it already.
I've also had it freeze twice on me. Went from rooted Stock to JI6 using Odin. /shrug
Same issue after applying JI6 OTA. I unrooted before applying the OTA, but have now reapplied OCLF with stock.
Same issue. Frozen hard twice. Browser exits randomly. Battery drains about twice as fast as before JI6.
I went from fresh Stock to JI6 via Odin. I don't know if I can wait for Froyo. I may just go back to stock again, even with the broken GPS.
I bet the OP has a bunch of apps installed.
A lot of people are blaming the update, but I'm almost sure there are many rogue apps in the marketplace, because last night I was getting freezes and after I uninstalled all the apps I don't actually need (or use very frequently) all of the freezing just stopped. The phone runs smoothly now. And removing those apps + removing the Task Manager widget from one of my screens increased my battery life by ~200%.
I installed BioNix 1.9.1 (with JI6) and I'm still getting occasional freezes, but I'm wondering if they are due to Angry Birds which I installed at the same time as my original JI6 OTA update. I'm seeing some reports (forum.androidcentral.com/motorola-droid/38906-freezes-weird-stuff-angry-birds.html) , but I have no idea if this is a valid idea.
Anyone else seeing freezes with JI6, but not angry birds?
I've also been having freezing problems, and I think they're GPS related.
The last time was last Friday. I was driving down to Washington DC using my phone for turn-by-turn navigation, and it froze about 1/3 of the way there. I had to pull the battery out to restart. When I got to my destination, I was using Maps and then the browser, and while the GPS icon was on the notification bar, telling me it was trying to find my position, my phone froze again. Again, I had to pull the battery out. Both happened within around a 1.5-2 hour period. I realized it may be due to the GPS, so I turned off GPS right away. It's now Monday afternoon and my phone hasn't frozen since.

[Q] My Device All Of A Sudden Is VERY Buggy

I have a Sprint Galaxy Note 4, it's rooted but that it.. NO custom ROM or custom, anything really. Just a Galaxy Note 4 that has root access!
I've had my device for a total for maybe.. 5 months, and it's been rooted since last week.
Since yesterday, all of a sudden my phone is extremely buggy. All of these errors and problems have NEVER occurred before, and now they occur extremely frequently.:
-Scrolling through Gallery app is super jerky, it's like my phone things I'm trying to scroll up and down with 4 fingers on the screen at once. (This has never happened until yesterday)
-Messaging app takes sometimes 6 secconds to load up. (This has never happened until yesterday)
-Phone will sometimes make it to 0% then die, or sometimes die completely when at 15-20%. (This has never happened until yesterday)
-Nova Launcher crashes maybe 4 times a day on average (This has never happened until yesterday)
By "Yesterday" I mean.. probably yesterday, but possibly just the last several days in general. I literally didn't do anything to my phone that would've caused this, other than simply rooting it. I just rooted it, no custom ROM or custom anything else..
Anyone know why this may be happening, or any fixes? Thanks!
back everything up. flash stock ROM through Odin or Kies then restore.
Before that try enter *#2663# into the dialer and then click TSP FW Update

Freezing and Crashing

I received my 32G model on Nov 28. Firmware MDA89D. Pure stock unmodified in any way. Not even using screen protection or cases. Setup as a new device, not copy from another existing device. I've been getting randon freezes and crashes. When it froze, it did not respond to any touch input or any key input. The only way to get back is to hold down the power button to do a force reboot. It seemed to have settled over the last few days. What I do have on an ongoing basis is crashes. When I use Google map navigation, the phone will work for a few minutes and the screen went black followed by a reboot. It did it on 2 consecutive days already.
Is it just me having this problem therefore a defective unit or is it the OS / Software problem.

That is strange...I haven't had that kind of behavior on my Nexus 6-works without a problem-never freezes or reboots...now I know the Amazon app would do something to my Nexus 6 I don't know what but when I install it-my phone with reboot randomly or shut down...ever since I uninstalled it-no issues-for months.
Try running safe mode and see if it does it again-that way you will know if it is an app that's causing the issues. This is how it's done: http://www.greenbot.com/article/2923927/how-to-restart-your-android-phone-into-safe-mode.html
You can always try a factory reset as well....have you tried updating to the most recent factory image from Google?

I've been experiencing the black screen freeze frequently since getting the phone only a couple days ago. No other lockups however. Also running pure stock.
I too have the same issue. Screen goes blank and lock ups. Also running pure edition...
Same. Interestingly, in my case, it seemed to happen most frequently when using Hangouts.
I have another post that describes random reboot and I believe they are related. Long story short. I believe either the factory reset + software update fixed it, or it's a hardware problem problem. While I wait for the replacement, I only had one random reboot. Of course the new phone is rock solid. It's only been a couple of days. I would have a few by now if I'm still on original phone _ original firmware.

I'm having the same issue. So no random freeze leading to reboot with ur rma device?

What I'm trying to say is don't panic and RMA your device. Do a factory reset and make sure you're on the latest firmware. Mine was OK after the first self-reboot during setup after factory reset but has been good while waiting for the RMA to arrive. To answer your question, the new device has been perfect but it's only been 48 hours.
I am facing a similar issue with my Nexus 6P, can anyone please help me with it?
On any rom, whatsoever, I get reboot when I turn the Google Maps Navigation On.
After few minutes, phone just reboots
I havent yet tried stock, any idea how can I find the root cause? I have cleared data for maps, also I have tried to uninstall maps with TiBackup and installed fresh from Play Store

Yup same stuff going on over here with mine. It locks up and reboots even after clearing cache and rebooting only a few hours earlier. Have done 2 factory resets and am on the latest OTA update. I also noticed that I have to clear the cached data every day, sometimes multiple times a day to keep device running smoothly. This really concerns me with a device that's less than 2 weeks old. I also have only a handful of basic apps( Fb, YouTube, Spotify). Really thinking about returning it. When the phone runs right its great, but all the issues make me nervous. Might be time for a Note 5? I am just getting used to this phone and would hate to leave it though. Interested to see if the first major marshmallow update fixes these problems.

Mine actually had one random freeze and reboot after factory reset then nothing for 48 hours after that. Of course I rma'd mine and I'm glad I did. Screen is on the colder side with even volume speakers on the second unit. Sending my original one back.

I'm just about ready to RMA. I've tried factory resets, cache wipes and just recently updated to the latest stock MDB08M. It was fine for a day or two but now the lockups are increasing.
As others have said, by any other metric this is one of the best phones I've had. This freeze/reboot thing is getting annoying and even if it isn't happening to every user it's happening to enough to be of some concern.
I'm facing app closures, my gmail app keeps crashing, it happened on my graphite nexus 6p, and now same thing on my frosty 6p. Its not just gmail, it's also chrome now. Maybe i should have not restored from my previous device.
what's this?
I came to this thread expecting a lot more of a technical discussion (the site is called xda DEVELOPERS after all).. but instead all i see is "oh my phone is crashing.. i'm gonna RMA this sucks) posts.. moving on to android enthusiasts on stack exchange thank you very much
upgrading to 6.0.1 fixed it!

Random reboots on my S4

Hi,
I have a S4 i9505 (Snapdragon 600) with Android 5.0.1. Still stock, no root, european version (with a spanish rom).
In the last months my S4 has suffered for many random reboots in different situations: the 2 most common are scrolling the gallery and turning on the screen (with home button or power button). But it happens also with using several app.
The screen freezes and after some seconds it reboots. After reboots works fine for a while.
Number of random reboots starting recording in june 2017:
june: 7
july: 2
august: 4
september: 7
october: 9
november: 17
december: 10
january 2018: 7
have stop recording after january as in february I started using a new phone.
I've bought a new samsung battery and I've also did a hard reset without installing any third app but there are still random reboots. What's weird is that sometimes it works fine for 1-2 weeks and sometimes it reboots 2-3 times a day with the same use.
On average it reboots 8 times a month.
For your experience is it normal for a S4 to suffer for so many reboots? How stable is your stock S4 (snapdragon 600) with Android 5.0.1? Or maybe there is an hardware problem on the logic board?
Thanks!
Up! Anyone can help?
The s4 should not be experiencing random reboots. I have had an s4 for years (now on a iPhone) and never had these reboots.
This could be an indication of a hardware problem since it's happening on a stock ROM with no third party apps.

Thanks for reply! I haven't seen your reply until now and I've already wrote a similar post in
https://forum.xda-developers.com/galaxy-s4/help/galaxy-s4-random-reboot-t3469346/page4
Sorry for double post!
Anyway what drives me crazy is that sometimes it works fine for 1-2 weeks and sometimes it reboots 2-3 times a day even with same usage.
That is strange the reboot behaviour is not normal.
Not sure that you can do anything else other than changing the motherboard.

That's what I was thinking.
For example tapping repeatedly "Drawer Icon" -> "Back Button" -> "Drawer Icon" -> "Back Button" for 4-5 times freezes and reboots the phone (one time freezed and stuck, I had to remove battery). But in the last days this problem has disappeared.
As far as you know a problem that comes and disappeared like a ghost is usually related to hardware or software issue?
Only other ting would be to re-flash the latest stock ROM, factory reset, and use it for a while to see if it reboots.

You mean re-flash with Odin?
You said before you had an s4 for years and never had these reboots. So you never had a reboot, not even once a year? Is the stock rom so stable? Is the stock Samsung rom the most stable rom around?
Yes, reflash with Odin.
The most stable ROM is the stock ROM.
I may have had reboots but they were probably due to apps. I never had random reboots throughout the day on a stock ROM and I don't recall my phone suffering from random reboots. My sister-in-law and nephew have the same phone and they don't have random reboots.
This confirms me even more that probably there is an hardware problem.
Thanks a lot for your help!

Weird System Bugs/ Issues Stock

Hi, I have owned a One Plus 6T for a few years now, didn't have many issues, until the last few months. I used to be on Android 10. (something) can't remember and the issues I'm about to describe happened on that version too. I have recently updated to Android 11.1.1.1 and the problems still persisted. And I've run a factory reset a few days ago and that still hasn't solved the issues. My bootloader is unlocked and I am not rooted.
Issues:
1. Phone randomly rebooting (almost like there isn't any RAM but there's over a gig spare) eg Ill be listening to spotify and suddenly phone reboots
2. Extreme System UI delay/lag and screen lag. This is the weird one. Happens at completely random times. Phone will slow down extremely to the point where nothing will be responding. For example if I click the power button to look at the lock screen the screen will just stay black for ages. Apps will not open etc. Can barely even swipe or do anything, it happens multiple times a day too.
I was wondering if anybody knew why this might be occurring, considering I am running a fresh install, unless it comes down to just bad software.
