I am having a very annoying problem with my Rogers I727R S2 phone on ICS stock.
The problem started to increase in frequency to become a real pain.
My phone would suddenly freeze and stop responding to screen touches for a bit, sometimes as long as 2 minutes, before bouncing back. When it comes back, it initializes as if it is restarting, so I would feel a vibration, lose all open applications and see icons start appearing on notification bar one by one. The media scanner would start working and software installed on SD card start appearing.
The problem happens spontaneously and out of the blue. It was occurring at less intensity on gingerbread before upgrading to ICS. After upgrading, it was not that frequent until only recently.
I noticed the problem goes away when I remove the SD card or when I am on flight mode with no Wi-Fi. I changed the SD card but this did not help. Connecting from home or work does not differ, so a problem with Wi-Fi would be ruled out. I once had a problem with home Wi-Fi when somehow the router’s DNS was not resolving, when this problem of mine was at its prime, and my phone was rendered unusable as it only takes couple of minutes before acting up.
I spent quite long time searching for an answer and so far no luck
I just placed a video illustration of the problem, and hope to get feedback on even where to head.

Try a different launcher.
the only way to troubleshoot is to start from scratch, read my 2nd link in my sig to restore to stock ics, reset within the recovery when odin finishes flashing, also keep out your sdcard out just to make sure your sdcard or its slot is not the problem. if still having probs its hardware failure, should still be under warranty

I went through your instructions restoring to stock ICS (which did not wipe my data as I thought it would). This did not help though, and the problem persisted. After that I decided to a hard factory reset. This appears to have done the job and my phone was working very smoothly.
Because my phone is rooted, I restored to the buggy stock again using CWM in hope to be able to figure out how to my migrate my purchased software, data and settings after hard reset. I wonder if there is a way to preserve important files even with replacing systems. I want to hard reset again but I keep my important information

after restoring stock perform a reset in the recovery, if old data is still there after reset its a hw defect in the nand
edit: reread your post so nm what i just posted, use titu or other backup software
Hi all. 1st post here.
I've been having a lot of trouble with my Galaxy Tab 2 lately. I rooted it a long time ago. Never had trouble with it. A few days ago, after charging it, I tried to start it, but when it starter, after a minute or so, it restarted. Normally the tablet only did that when it was froze due to many apps or processes being used at the same time. The problem is that the tablet never started properly after that one time. It's on some type of infinite loop. It starts, stays on for 1 or 2 minutes and then freezes and restarts. Well, i thought what most people would think at the moment: "I need to reset the tablet". I went to Recovery mod, made the format, but when the tablet rebooted, everything was untouched. No format. Odd to me. I then tried to return to stock. If it after that the problem was still there, at least I could be able to call for warranty. Odin gave me a lot of failed errors when I was trying but there was once that it said "Pass". Rebooted, still the same. Updated the recovery, tried to format, still the same. I'm running out of options right now. I don't really know what can be the problem and how can I fix it. I thought that if there was a way to format it like in recovery but using my PC it would do something (or not)
I appreciate any type of help.
i just got my note pro 12.2 wifi version (international) a few days ago and already experiencing problems, firstly the wifi was so slow so i updated it OTA to the latest stock firmware i can't remember what it is but it's the latest official 4.4.2 they have and that improved the wifi but now i'm encountering issues of rebooting randomly after using facebook app. it's always after i lock the screen it suddenly reboots after 2 mins or something especially if i have say been using a lot of memory for it.. ie if i scroll down 4000 friends that's when it always reboots once i lock the screen. is this liekly to be hardware or software issue or an app issue?
i have only had it a few days so haven't managed to play with it enough to test it to the max.
just now it rebooted and i played one youtube HD video and used multi window to use the facebook app (old version 7.0 - i like this version).. but i hadn't used the facebook app that much while on, the only thing i did different was i plugged in my samsung s3 charger into the note pro to test how long it would take to charge using a usb 2.0 connection instead. it's official charger official cable, is that likely to cause reboot issues?
previously it was just after using facebook for a long time for a ram intensive amount, i also tested it after reboot and using facebook a bit and locking screen and it didn't reboot so it made me think ok it's just when facebook is being used a lot and all the ram and memory is exhausted caching 4000 friends viewing so i didn't think anything of it.
is this likely to be hardware or software issue? are hardware issues ever the main problem with rebooting?
I know the usual tests, having to use odin to flash official firmware, trying a different facebook version, removing and not using facebook at all and see if it still reboots and lastly factory reset.
ideally i'd like to avoid all of those things as it is a major hassle and i can live with the reboot issue provided it isn't a hardware problem. is there anyway to test it to know for certain it is hardware and not software and the app?
edit: it keeps rebooting even if i dont use the app
seems to happen when i lock the screen sometimes it just reboots randomly.
anyone else have this?
You could try to remove that facebook app and see if that fixes the problem.
does anyone know what is causing this?? is it hardware?
i've factory reset removed all apps, then added one app at a time then added about 6gb of videos and added wakelock detector. all seemed fine
then i tried to unmount the sd card and then it rebooted.. why is it doing this??

Could it be a bad sector on the SD card? I'd long format it using a pc to be sure.

it's not the faceboook k app i've realised now it just coincidentally seemed to be that as it is ram intensive.
i factory reseted and then put the app back on but didn't log in. 3 times it has rebooted by itself over different scenarios.. 1 plugging in a samsung usb 2.0 charger from a samsung s3, 2 when unmounting sd card, 3 when closing the screen when any ram intensive app is in the background (there's still like 500mb of ram left!! i dont know why it's rebooting like this.
i can't figure it out. is anyone else having these issues? im not sure if it's a kitkat 4.4.2 issue.. reading forums from other users with different devices i'm seeing the reboot issue coming up alot especially on the s4.
http://forum.xda-developers.com/xposed/modules/samsung-kitkat-systemserver-crash-fix-t2806046/page22
but i dont know for certain if it's a hardware issue.
my next steps which i really want to avoid is to factory reset AGAIN and not load any apps (the problem with this is it requires a certain amount of ram intensity to be used before it randomly happens.. if i dont add any apps like instagram or facebook or tumblr i can't get it back to the state where it reboots randomly)
i've also enabled all apps (i usually disable all the bloatware i can without being rooted) but it does bring up errors of android.core.process has stopped etc and some gapps errors (im hoping this is the cause of the reboot) and see if it reboots. it's difficult recreating the scenario consistently.
i udnerstand it might reboot if you've overused the memory but it clearly shows lots is free so i can't figure out what is causing it?
my next step after all this is to flash the latest version of stock so i can't put it down to the OTA updates that is causing it. if that fails i revert to odin to flash the original 4.4.2 it came with.. and failing that i'll have to return it
does anyone have any ideas whether it is hardware (maybe the power button is slightly off so when you press down it in a certain angle it triggers a restart?)
or is the motherboard or corrupted sector of the memory which when it writes over it causes the reboot?
i always assumed reboot issues were normally always firmware issues and not hardware.. surely samsungs quality control is a bit better than that??
If it were me I would yank the microsd card out, factory reset, set up just my gmail without allowing auto backup/restore and apply all updates. I'd then let the tablet run for a full day and use it just for web browsing and Youtube to see if the problem is still there. I would not install anything for at least a day, including the microsd card. This would be as stock as one could get and rule out the possibility of it being any software that I installed or the microsd that I was using.
I suspect it's software but the only way to know is to be patient and test it out for sure.

Hi,
same tablet, bought there is 3 weeks. I installed the latest firmware update (XXUANI1)
I rooted the tablet (to allow sd-card writing).
and that's it.
like some of you, I have random reboot.
I can't remember if it happened before the root or not. I think that yes, but I am not 100% sure.
I don't see anyone reported that the root cause random reboot...
it is really random. sometime, the tablet stay one night without reboot, sometime, I can have 3 reboot in one hour.
I don't find what kind of application is causing that issue.
I really believe that it is software. before the firmware update, I stayed 2 weeks without any issue.
I tried to reboot in recovery mode, and wipe the cache, without success.
I will probably try to do a factory reset...

Assuming you have custom recovery installed as well; have you tried wiping dalvic? It will force applications to recompile and possibly fix a corrupted application or its associated files.
Hi,
I just checke.…
I was thinking that the root method was not setting the knox flag, so i was thinking there is no recovery in the file flashed… .
I was wrong.
My waranty is void, knox is set. I still have no custom recovery : in the file provided by chainfire, there is a recovery which is probably coming from samsunG…
So i will install a new recovery and try to wipe all caches dalvik.etc.
Hi,
since my knox is set now :
I tried to install TWRP recovery, which allow me to do a wipe of the cache AND dalvik Cache.
it did not resolved anything. the tablet still reboots randomly.
then, I decided to restart from scratch :
I flashed the same firmware I had, using ODIN, and do not root it.
this is this firmware : http://www.sammobile.com/firmwares/database/SM-P900/XEF/
I will keep you updated if it solve the reboot issue or not.
thanks

Hi
I had the same problem and also thought it was the power button that was faulty but then I flashed the previous firmware then tried to use it a bit and no reboots since so I guess samsung released a new firmware that solved the slow wifi problem but then boosted it a little too much or so it seems judging by the reboots whenever there's too much overload.
So I guess for now I will stick with an older firmware
oops... it rebooted while I was surfing the play store so I guess I spoke too soon
Device is locked and never been rooted. Took the 5.1.1 update and apps like Netflix and HBO GO fail unerringly after 1-5 minutes of streaming.
Somethings...
-Neither app actually crashes to the desktop. It crashes to the apps main menu.
-Both apps attempt to "redraw" (3-4 times in quick succession) after the player fails, then I can usually reload the video.
I have...
-Cleared data/cache
-uninstall/reinstall the apps
-did a full factory reset
ANY thoughts would be really appreciated. Not having much like finding any resolution here. Thx in advance
I have the same problem. I have flashed the latest firmware with Kies and Odin to make sure there were not issues and still Netflix stops playing as does Youtube, Plex etc...
I have spent around 8 hours trying to find a fix to no avail. I made sure that Display > Smart screen options were disabled. In developer options I checked Force GPU rendering and Turn off hardware overlays. I also tried and unending list of other settings to no avail. Does anyone have any ideas?
Thanks Chris

Go in to About Device in Settings. Does your status show "custom?" If it does, remove your SD card and transfer the files on it to your PC. Reformat the card on your Note and afterwards put the files back on it. There's a strange SD card glitch that occasionally causes the system status to show custom when it's not.

No my Device Status is Official. I tried using a different launcher "Google Now" hoping that a more simple launcher might clear things up but no luck. Netflix stops playing after a couple of minutes and youtube pauses. I want to be clear Netflix does not crash it just goes back to the menu where I can hit play again.
This fixed my tablet!
I may have found a fix. At least this fixed the issue for me.
The Back Story: (for you to compare similarities in device errors)
I have been having the same which started after the update. and my tablet has never been rooted either. I chatted with Samsung several times. They acted like this has never happened before and they kept saying it might be a bad wifi antenna. Which sounded like BS since I was able to surf the web and even watch youtube through chrome no problem. If I tried to watch videos on youtube, netflix, vudu it would reset as you mentioned. I even noticed that when I was using Polaris word it would erase everthying I had written randonmly. Samsung also tried to say it could be the app itself. Which I instantly doubted since the apps are made by different companies. I did the factory reset. I even took the tablet to Best Buy to have them do a system re-flash with no luck. I almost sent the tablet to samsung to have them try to fix it, but I had a feeling it was something easy to fix and I could save myself money.
THE FIX:........ I have no clue why this worked. If anyone knows why it worked I sure wouldn't mind hearing your thought!
1. Pop the sim card out.
2. Try playing videos on your apps. (Be sure to check a couple apps) It worked like a charm for me. I dont think I had to reboot to get it to work, but the fix stays after a reboot.
3. What you do not want to do is put the sim card back in because you will have the issue again.
- If you do put the card back in dont worry. You can simply remove it again and it will work again.
One thing to keep in mind.....I stopped my subscription on my verizon data plan. So it doesn't matter to me if the sim card is in. So If you still use Verizon Data plan and this fix worked then you should contact Verizon and let them know whats going on. Maybe you just need a new Sim Card. Like I said I don't know why it worked, but it did. I had data turned off completely so my device shouldn't have been trying to use anything other than wifi.
Please let me know if this works for you as well!
Thanks are always welcome!

It Worked!!!
Thanks very much for the suggestion. As it turns out the tablet came to me with a sim card in it. I never intended on using it with Verizon so I did not look. Once I removed the inactive sim card everything worked great.
Thanks again I really appreciate the help.
Last night, I was trying to play a 1080p, 60 fps video while connected to data (HSPA), and suddenly my phone died (with 80% battery) and entered into a neverending bootloop.
After I came home, I tried Normal Flash via the LG Flash Tool, and I successfully got it to boot into the OS, only to have it bootloop again after unlocking the phone. Next I tried to CSE Flash which removes literally everything, and it bootlooped the first instance, after restarting again, it somehow managed to enter the login screen and I was able to navigate for a little bit.
After that, I deduced that the coast was clear and that it was safe to rebuild my apps and all, but after I tried to reconnect to our WiFi (I had sim and SD card out), it bootlooped again!
Now I'm on my 2nd CSE Flash to have it forget our WiFi network, and try to see if I can still use the phone functionality. If it can connect to a network and let me make calls/texts it's fine. However, has anyone experienced this before? How did you fix it? What was the problem? My initial deduction was that an application or something was causing the bootlooping, but after a fresh CSE Flash, I don't think that's the case. I also doubt it could be a battery problem, since this phone is barely over a year old (around 4 months over a year) and has not suffered any kind of heavy/extreme damage.
Right now I'm trying to revert it back to Lollipop, if that doesn't work, then I'll try KitKat and see what I get.
Literally, just started facing this issue. Did reverting to lollipop work.
