Galaxy SII reboots (crashes) randomly - Android Q&A, Help & Troubleshooting

Good day to all.
I noticed that after DXKL3 rom, my phone reboots randomly. Sometimes it happens while I'm playing games; sometimes when I'm just about to click something; sometimes when I'm just tinkering with it.
Anyone experienced this?

Is your device overclocked?

No, sir, it ain't. Here's what I did so far:
1) I cleared by browser cache from the application...
2) I formatted my SD card using the SD Formatter from this link...
3) I installed WatchDog just in case something goes wrong.
4) I move all my apps to my phone. No more apps on my SD.
I'll update my activities as I progress... By the way, I don't have Dolphin browser since day 1.
It was quite hard to narrow down which one was the culprit because I did all the abovementioned procedures at the same time without testing which of them works or not. But ever since I applied those procedures, I never got any random reboot up to this point yet.

It's possible to be #4. Maybe you moved an app to the SD which was supposed to stay on the phone. #'s 1-3 don't (usually) cause that issue.

I have my bet on that too, sir. I just wonder why some apps were designed to be allowed to be moved on SD but might cause problems.
Anyway, up to this moment, I still got no random reboot. I'm about to conclude that it's totally cured.

[Q] Fix for gallery freeze?

I just recently got the vibrant and got the OTA the same day, the gallery freezes about half the time, and about half of the time that it freezes i have to pull the battery, i cant get to task manager or put the phone to sleep and wake it up.
I searched google and there are alot of links regarding it but i didnt find any that gave any ideas to fix it.
I searched this forum and nothing came up. Anyway, I have a class 6 card, the gallery on my nexus is very quick and has never frozen, so it is definitely the phone.
In my experience with the g1, MT3g, N1 and now this vibrant, any time ive received an OTA it has come with costs, it always brings fixes and features but also causes new problems, large and small. So I dont doubt what I found while searching, that the gallery issue is a result of the recent OTA for the GPS fix. Anyway, its kind of silly that this awesome, technologically advanced device freezes when you open up one of the native apps. But can we do anything about it? And if not, is it likely that Samsung will address it in another OTA? thanks
edit: ive also just recently had my phone just turn off every day or so, and it wont power back on until i pull the battery. Maybe these 2 issues mean i have a defective device? Or is this par for the course with the tmobile galaxy s?
Overclock your phone to only run at 800-1000MHz. It completely solved this for me, 400-1000MHz still hiccups.
thank you, yet another reason to root i suppose...
So no way to fix that with stock phone? =(

overclock huh,, i never tried i am there is a link here let me go look or how did u do it

That is odd, I've never had my gallery freeze or my phone reboot... Are you sure you don't have some rogue app? Perhaps you should factory reset and start fresh? Do you have any "junk" apps on your phone (stupid apps)?
I had a freeze on opening gallery right after the JI6 was released. I think it was trying to recreate the thumbnails from scratch and download pics from my Picasa acct.
Happened one time only and I actually had to pull the battery since it went unresponsive. Never had a problem after that.
~SB
perhaps unmount and remount the INTERNAL memory card. I've done this before just because I saw it as a suggestion and it recreated my gallery.
I having the same issue. I am ready to delete it and use a different app. Is that possible?

If you're rooted you can probably remove it.
I have tried factory reset so I don't think its a rogue app. I got the ota the day I got the phone so I can't compare before and after. If some people aren't having the issue period maybe a warranty replacement would resolve it. Of course, if we do end up getting froyo maybe that's something that will improve. Love the phone either way, I just get fed up with stuff like gallery freeze, random reboot, GPS issues, etc... stuff that i would think shouldn't get past product testing.
OP, this is discussed at the thread below. (use the search next time)
You are not the only one having this issue.
http://forum.xda-developers.com/showthread.php?t=805784
Quick Summary:
- Even with the removable card blank, the Gallery still have the same issues.
- I did a complete wipe and still have the same issues.
- I cleared data through System Settings which recreated thumbnails and other data, still have the same issues.

Wow i am so sick of reading some loser tell somebody to "search next time". You'll be so very relieved to know that I actually did search, and all i found out is that you dont have any friends. But honestly I did find your thread, however it didnt seem to me to be on point with what i wanted to ask specifically. Your post says that "watchdog" told you your gallery is a "resource hog" and that you have to kill it. I dont know what watchdog is, nothing told me anything i just cant get into my gallery app very often, so that didnt seem applicable. Also, i got ji6 the day i got my phone so putting the gallery issue in the context you did ("since ji6 update") didnt mean anything to me, i dont anything about this phone pre-ji6 update. All I know is that my gallery app sucks, your thread was a bit technical for me to be able to apply to my particular issue
Anyway, now my gallery freezes every single time i initially try to open it, i have had to pull the battery 6 times in a row, it works after the pull. This has been my favorite android phone (of 4) but now i just want to set it on fire and run over it with my car. I guess Samsung and Android arent interested in making their $600 products work, does anybody know how i can fix my phone so that it does what it is supposed to? Also im not rooted which i assume probably makes it impossible for me to fix? thanks for any help.

[Q] SGS2 with CM9 Freezes suddenly. ROM problem?

I periodically find my phone in a frozen state/shut down (at least once a day or during the night)
I have the latest nightly CM9. I'm wondering if the freezes are caused by the ROM or i have some hardware problem or an rouge app or something.
Is there a way to see a log history of all processes so i could pin down what's happening just before a freeze? is there a better way to do this?
Thanks all

The biggest problem in cm9 is when you set your voltages/cpu too low, this can cause your device to lock up when turning it on again/opening lockscreen. Another problem which is usually the case is that you have a misbehaving app. The easiest way to counter these little niggles I have found is to do a complete wipe, format your sd card, format system etc, then attach sgs2 to pc via usb, mount your sd card and transfer cm9rom.zip to sd card. Only then flash your cm9 to your sd card in recovery after unmounting and disconnecting from pc of course. This lets you kind of narrow down the problem as you will know that you do not have any files/folders/apps from a previous rom install that are causing issues. I always do this when installing a rom, even if it is just a nightly update, since I used to get problems like yours, I do this now and have 98% less issues. But what I think you have most likely done is to underclock your device too greatly. Also, if you are using cpu profiles, make sure you are not setting screen off profile too low, otherwise it will most certainly freeze on open. Anyways, cover these bases and you should be golden. It is not a rom problem.

[Q] hydrogen temple run crashing

i recently installed hydrog3n-ics-20120418-sgs2 and temple run keeps stopping the phone completely.
i have to take battery out to start again.
very frustrating anybody had this problem at all?
sorry if posted in wrong forum
happens on all roms I believe (definitely cm9 based... though I'm on a Sammy rom and it's also happening, though might be because I'm undervolted) - most annoyingly is, it also leads to the loss of data... I saw someone mentioning that the developers were aware of it...

[Q] Apps disappear / uninstall by themselves.

I have no idea what could be causing this. I've never heard of anything like it, and I have yet to find any posts or anything on Google pertaining to it. The problem is simple. I install an app or game. Play or use it. Go do something else for 20 minutes to an hour come back expecting to use said app, and its gone. Its not in the launcher or manage apps, and play store acts as if it wasn't yet installed. I can go to market again to install it but that's just bothersome. I'm on an 8gb nook tab running an emmc install of cm10, looks like its the 2012-9-3 acclaim build according to about tab. Other than that I'm not sure which ROM exactly.
Any thoughts would be awesome.

I only downloaded this ROM about four days ago. That combined with the fact that that was my second post on xda, it wouldn't be far fetched to assume I didn't know there was an updated version. May I ask what your recommendation of most stable cm10 ROM would be?

Is there a "place holder" icon in place of the disappeared app? (home screen and app drawer, either or both) Would appear as a generic android icon.
Also, what apps are disappearing specifically?

When Ext-Sd card auto unmounts (known bug) everything installed on it (because ext-sdcard are default one /sdcard1) is then shown as a green android without their normal icon.
I've been having this issue as well with Business Calendar Pro. It isn't installed to the SDCARD. I haven't had the problem with the latest version of the ROM though.

I can't compare it to stock or CM7, though -- I haven't run either stock or CM7 since April or so. It does seem to suck the battery down much faster than Chris' CM10, though. To deal with that, I've been doing a full power-off (long press and select "Power Off") instead of a soft power-off when I know I won't be using the tablet for a while.

Almost any app. Here's an updated play by play.
Install app. App can be used.
After a while it disappears.
Can reinstall and use again.
Usually disappears again.
If tab is rebooted apps reappear. Icon and all.
If you attempt to open they force close. I don't remember the error message.
This mostly happens on large apps or games.
I'm gonna attempt to update my ROM and see if it still has the same problems.
Updated to the latest cherry picks ROM. I wiped and cleared everything. Same problem. Same symptoms. Any thoughts on causes and possible solutions? Or is this just a bug with the ROM?

I've experienced a similar issue, and it appears to be the result of the SD card getting (forcibly?) unmounted while sleeping. I have no idea how to prevent it other than moving all apps to internal storage if possible. Maybe ensuring that any apps the rely on storing data on the SD card are terminated before sleeping?
FWIW, I've had the same thing happen in the past with the stock BN ROM so it wasn't a huge surprise to me when it happened running CM10.

Okay, so the exact same thing happened that the OP described to me this morning on 27/09. I had moved several apps to the SD card and then when I came back to my Nook about a half-hour later, all those apps showed as Android icons and could not be launched. Rebooting made it possible to launch the apps again and brought back the normal icons.
Update: Perhaps it's coincidence but it seems that whenever I manually disable WiFi before sleeping my Nook (running 27/09 here), then everything is fine. However, if I forget to disable WiFi, then for some reason the SD has a chance to be unmounted while sleeping which requires me to re-install any apps that are installed on the SD card or that depend on the SD card for normal use.
I'm also thinking that maybe it doesn't have anything at all to do with WiFi being enabled, but instead perhaps it's just having apps running that depend on the SD when the unit sleeps (such as XDA premium which I've had to re-install several times over the last couple of days ) .
In all, it seems like a really vague and random issue that occurs and reiterating my previous posts, I've seen the SD card get unmounted using the original ROM so I'm just not sure what the deal is here.
I have a problem,with my tablet. I found that 3 of my favour apps has disappeared from my apps list and tablet . I don,'t uninstalled it. What can I do to recover an install it again. When I go in my Googly Store my apps list The 3 apps that is disappeared is not listed there. The 3 apps thats is disappeared is Mxit beta, Google translate and Opera Mini web browser. Is there anything I can do to find this disappered apps on my MTN Steppa 7" Tablet. Finally When I try to download a app from the webside or google play store it shows dowloading by don,t stop the download arrow flashing on and on even when I swiched off the mobile data it still shows downloading but nothing stops. When Switched on the Mini data the the download app is Queued. What can I do to stopit and removed it.
i hope really that you can help mevwhit this problem.

[Q] i777 with Omni KK. Music stops playing suddenly.

I'm using the latest nightly, but I've been seeing this pretty much since I started using KitKat on my phone.
The problem goes like this. I'm listening to music, and after a random amount of time, the music stops playing and the player hangs. It doesn't matter if I kill it. I have to reboot the phone to make it work again. I've tried wiping the player's cache as well as using different players and it's the same.
I've been noticing a pattern with several apps unrelated to music. The Opendelta app which I use for upgrading nightlies sometimes also hangs when patching the zip, and provides an ETA that finishes about the same time as the Universe itself.
The phone also hangs when I'm copying files in USB storage mode from my computer.
I think I read over the i9100 forums that the KitKat driver for these phone's storage is really buggy or something, and thus behaves like that.
Has anyone have had the same problem?
Is there any hope for such a driver to be fixed in any ROM or Kernel for the i777?
Should I just revert to 4.3?
I'm not very Android/Linux savvy, but I could provide system logs if needed.

This is a known issue, and there's no fix for it at this time (that I'm aware of). It has to do with Exynos devices, so you're not alone.

Hadn't seen the exFAT bit, but it isn't linked exclusively to the external SD. It happens with the internal as well. And, as I said before, with other apps besides music.

Oh, I see.
I think I'll just get this over with and flash a nice JB ROM.
Just out of curiosity, has Exynos support so far been depending on Samsung or are the drivers reverse engineered by someone?
Based on the thread, and what you've reported in the OP, these issues are one and the same.
The thread agrees with you, that the issue is NOT exclusively associated with the external SD. Folks are re-formatting both internal AND external SD, and reporting positive results.
further, the Open delta issue is suspected to be related, as a "fuse daemon" issue.
Try reading the thread, even if only starting from page 17.
Happy Flashing
