the phone always reboot
been usin a few months the phone without movin apps to sd card
phone has no problem
right after i moved the apps
nothin happen
only when i restart the phone
it will start to restart every few minutes
its nothin to do wit the kernel modem n rom
i think its the apps problem
has anyone faced this kind of problem b4?
n i dun use ahem apps
most of my apps are
paid or free or from amazon n some from xda lolz
time to reflash again
lucky i just restart 1 phone
or else
both phones will compete to restart

Have you Tried using a different Kernel.
I have heard of people having issues with siyah kernel.
Maybe try CF root or speed mod kernel just to make sure its not the kernel

tested wit nimpo
tested wit abyss
tested wit speedmod
same thing

it can boot randomly when :
1. GSM signal is weak
2. Simcard is damaged or too old
3. Battery is too hot
4. Some APPS are moved to SD card (it allows you to move it, but actually, apps doesnt like it)
5. External SD card is slow, 4 or below classes, or too small sizes of sd cards (2GB-4GB) or too full of external sd card, ord sd card, or internal memory, etc. (shorly not enough memory
6. RAM!!!!!!, if more then 780mb ....,
7. too many WIDGETS...
8. too long standby
GUYS these are the main reasons, if you have all ok with above list, then you may have problems with OS, then flash and install back, or maybe HARDWARE PROBLEM (ram,cpu etc.)
GOOD LUCK!!!

most notably is the apps being moved to sd card
thanks

Random reboots

My phone's taking up this habit of rebooting (or so) randomly and automatically. It doesn't show any error or message and just reboots about twice a day... How did i know... My music widget did not display the last song paused and the up-time duration in the battery status was only a couple of hours (when infact I haven't shut it down)
Does anyone face this problem? Two things that could have made things go bad:
1. Using Verbatim Class 4 8gb MicroSDHC (heard problems with 8gb cards)
2. I rooted my phone partially (z4root did not work, superoneclick worked till halfway but I was able to access the root. Is there anything called incomplete rooting ). And after deleting the useless pre-installed apps... unrooted (again partially ) so that I can visit the Service Centre if things go worse.
Will the phone face problems if it reboots every once in a while. I don't mind it as long as it does not give me errors
Thanks,
Have you tried another sd?
AFAIK and with what i been seing arround here, that can be a card fault.
Incompatibilitys or something like that. It whouldn't be the first device like that.
Second change will be a hardware failure, wich is worst...
In my viewing, everything that is not normal, it's not good for your device.
So you should try to find a solution for it.
Cheers
my bad... Provided wrong info in the last post.
My system uptime is 48hrs which means my phone hasn't rebooted. But my status since last unplugged is 3 hrs but I last charged my phone more than 12hrs ago and I haven't plugged it to a computer as well. This number haas changed twice today...
I am thoroughly confused... Don't think there is a problem with my sd card as the phone runs perfect... All the games and music stored in the card play without problems... Guess I'll have to investigate further.
If anyone has any suggestion do let me know
I had this problem, too. And yes, It's SD-card related.
The uptime counter doesn't reset every time, but the last unplugged time does, as you noticed.
I flashed with the OC kernel, and surprisily, my phone is now fully stable. I don't know if the kernel did really the trick, but you could maybe give a try...

Can you please elaborate. Flashed the OC kernel... with what?
Did you reinstall the original firmware? Thanks!
I used the custom recovery and I selected the "Flash from zip file" option, it was very simple once you get the custom recovery working !
It doesn't erase your data, and it doesn't replace the original firmware, it's only a patch.
Do I need to install the custom recovery or is it pre-installed?
I don't think it is pre-installed. The key combination is not working. The phone starts up as usual.
And do we need to be rooted to carry this out. I'll try a soft reset meanwhile....
EDIT:
I got it. Need to use this "recovery-RA-GNM-thunderg-1.1.0.img" file to enable the custom recovery. If I put this file in the root of the sd card, will the key combination work? And what about the flash file? I'm sure it'll ask for the flash file when i select the option flash from sdcard.
I've experienced similar behavior, mostly using 3D apps. Google's Nav will usually result in a freeze/reboot. Quadrant has done it many times. When I was looking in logcat and bugreport it was showing messages like:
W/SharedBufferStack(223): waitForCondition(LockCondition) timed out (identity=223, status=0). CPU may be pegged. trying again.
I can't be positive if the SD card is the culprit (I haven't had a chance to replace the stock card yet), or if it's a software or hardware problem. I've only rooted and modified build.prop to enable jit and stagefright...and that's it.
edit:
Phone just crash when I opened the new updated google maps. Attached the logcat if anyone can glean some useful info from it.
Mine is definitely SD card related.... Flashed the original firmware but did not help. The SD card kept unmounting and remounting (no rebooting though).
Finally went back to the bundled sd card and no problem so far... But my other 8gb card is working perfectly in other phones and the pc as well (very good transfer speed and all) Even when I had it in my phone it was snappy.
But I read that a new firmware has been released. hopefully that will sort the issue... Fingers crossed.

There is a new version of the firmware, V10E.
You need to try that one.
I have the same phone and have no problems running a PNY 8 gig. card. I would try to re-rom your device but, be sure to back everything up first. If problem still persists try a differant sd card. ( class 3 or higher) I am currently running Cyanogen 2.3.3 with kernal update 2.6.32.9. OC to 806mhz. Semms to be running just fine. I hope that helps out.

Hi, I also facing the sd card problem. Can I update to v10e because my phone is v10a and rooted?
Before you guys upgrade, try this ....
Copy out all the data from your SD card, format your SD from the device, then copy the data back.
In addition, if you have shifted any Application data using the Move to SD card feature, suggest you move it back.
I used to have the reboot once a day, now I don't have it anymore ...
Formatting didn't work for me. Factory reset worked for a couple of weeks, but still got SD card unmounts with no apps moved to SD. The only thing that worked was physically removing the SD.
friend i got Phone on this saturday till then I was having problem of random reboot .like every time i play with my phone . i am using class 2 trascend 8gb made in taiwan micro sd card (but the problem of unmounting never occured to me).Main problem was of the random reboot .Then i flashed my phone with Unofficial port of CyanogenMod 7link here http://forum.xda-developers.com/showthread.php?t=946354 it worked so greatly and now i am running phone for more then 3 hours without any problem(hope this time will increase).
PS :This mod doesn't have market application of android any one who can provide market.apk or vending.apk beacuse its convinient to download from there

My Galaxy s2 keeps rebooting over and over because of sd card(special case)

i use Samsung galaxy s2 with the latest firmware version from Samsung kies (ginger bread 2.3.5) , the problem occurred after installing external SD card and move bunch of apps to it,i tried removing the external sd card from my device, the device stoped rebooting, when i insert it again the device keeps rebooting over and over, the problem is obviosley is moving apps to SD card, i tried to delete the content of the file (andro secure) in SD crad this file includes the moved applications from phone memory to external sd, the problem also stoped
i wasn't having this issue in 2.3.3 therefore
its one of the three:
1- android 2.3.5 do not accept lots of apps in external sd
or 2- there is a problem in a specific app in external sd which make the phone rebooting over and over but i don't know which app is causing the issue because i have lots of apps installed !
or- a problem in the newest firmware 2.3.5 as i heard many ppl having troubles with it
to fix the problem i did factory reset and the rebooting stopped but im scared now to move apps to sd card that the rebooting problem occur again as it happend to me twice after doning factory reset and move them.
i need your help guys, it's annoying to not be able to move apps to sd so the problem don't occur

I will be honestly: I didn't read all BUT
1) U have rebootings after putting files on external sd.
2) after factory reset problem was passed
3) copying again - reboot again
-> right?
1) U thought about wrong (damaged) files you copy?
2) Or maybe files which normally used from an app and this app now isn't able to use it because u moved?
Thing about and check this, I'm sure one of it would be the fold.

it's not copying actully, it's downloading the apps from market and move them from internal storage to external sd therefore i don't think it's a damage files case because they are a market apps however i move only compatible apps which doesn't have (lower right icon) in app2sd, install latest version of app2sd to know what (lower right icon) mean
I'm having the exact same problem! It just randomly started last night, I was playing the game "Blood and Glory" exited the game and around 2 minutes later after checking Facebook it started doing the boot loop.
I'm running the Sprint Epic Touch 4g with Android 2.3.6
I recently put in a 32g SD card a little over a week ago cause it seems the 16g internal is partitioned to only around 2gigs for apps and I have around 130 apps.
I use App2SD pro to move all my apps.
I'm having the same problem, I bought SanDisk SD Card 16GB. when I install it and moved all supported Apps to the SD Card the problem occurred and my SGS2 keeps rebooting over & over during the whole day.
One of my friends made a factory restore & installed the previous OS 2.3.4 and the problem disappeared!!
The thing is what if don't want to root my device and install 2.3.4 what we should do.... shall we keep the SD card only for Camera Pictures & Movies???
any suggestions???
Hey guys,
I am using SGS2 as well. My phone keeps rebooting like more than 2 times a day. randomly. I convince myself not to blame gingerbread2.3.5, thus i tried uninstall my apps in batch (5-10apps each round) and see which batch of my apps cause the prob, if they are not those who cause rebooting issue, i install them back (in phone space not SD card) but so far i still couldn't found and just few mins ago it rebooted again. it happens after the upgrade from 2.3.4 to 2.3.5, after i downloaded a few apps and updated a few apps. I will finish with the un-installation and re-installation.

saw this thread. people were talking about the Dolphin HD which caused the reboot issue, did you have Dolphin browser app installed?
I am having the same issue, too
It started on my S2 after the latest firmware update. I can unmount the SD card and the phone boots OK. I read somewhere that my SD card may have issues, so I purchased another and moved all of my files. The problem reoccurs with the new SD card. I do not have Dolphin browser installed.
I had this issue. I reformatted my sd card and then moved some apps and data back. One week reboot free. 32gb sandisk

In my SGS2 it reboots sometimes in the market, i dont know what to do...
test your sd card for errors...!? thats where i'd start
same problem ... do not restart I had to remove the microSD .. : (.... How do we fix??
SG2 rebooting all the time also
My Sg2 is rebooting every 20 minutes or so.
Is formatting the the SD card a fix?
Mine used to reboot 3 to 5 times a day. Did a factory reset and formatted the internal SD card and set everything backup without Dolphin browser and it's been good for about a week now, no more reboots.
Whether that was because of the rumor that Dolphin browser caused it or from the reformat of the sd card I don't know. But I'm happy none the less.
Got the same problem. It started 2 days ago, and the only fix I've found was to remove apps from my SD card.
From what I've tested :
- Formatting the SD card and copying back all the files doesn't help.
- Removing the SD card or having an empty one works.
- Uninstalling the Dolphin browser didn't help.
- Doubt it's a specific app causing the issue (nothing weird on my S2)
- Removing X number of apps on the SD card seems to work. Now I'm not sure if I had to clear a specific number of apps or a number of MBs, but it works (for now).
Hopefully we'll see a fix soon.

Yours sounds like a problem with an app...
Everyone else should test their sd cards for errors or try fixing bad sectors...
Used to happen on my previous phones with crap sd cards... Once I bought a decent good quality one its never happened
about a month and a half ago I removed dolphin and my reboots stopped. They started up again and my card became corrupted. Decided to go no-card for a while. Was fine for a month. Decided to go for a good deal on a sandisk 16 and 2 days later after moving a bunch of apps on the reboots are back.
Points to a card issue. I've been though 3 cards on this phone now and am about to reset it to factory and bring it in for diagnostics.
Driving me nuts.

I've got a Samsung class 10.. I Highly recommend

I got the same issue (2.3.5) and my SD Card is calss 4, the only way to avoid restart prob. Is to root and downgrade to 2.3.4
Waiting for any other feedback.
Any update Guys,,,,???
This problem is still occur in ICS leaks..
Without knowing this thread I have created similar thread here:
http://forum.xda-developers.com/showthread.php?p=21457609
Still, my thread is to gather data about how many user can reproduce this issue.
This issue is side effect starting from Samsung update 2.3.5..
The only way to avoid this issue is by downgrading to 2.3.4 or lower version.

-Ok, first try to move back your apps to the phone and test it.
-If it keeps rebooting just take out your SD card and keep the testing.
It will solove your problem for sure!
Thank you I will try to move back the apps to my phone and will see what will happen , will get back to you if anything improve
it can boot randomly when :

[Q] reading/writing from sd card terrible slows down

I have a stock ROM with windows 6.5, ROM version 1.66.487.2 WWE. I was personalize it to my taste and everytime, everything is working OK for a month or two and then everything goes to hell. Everything slows down just like that. When I try to open some (any) folder from my 8GB SD card with file explorer it took sooooo long. For a minute or two. Some apps (randomly;not specific one) need more than a minute to start.... In a meanwhile, I wasn't install any new app or change anything. I was try to format SD card,but nothing. Everything stays the same. As soon as I reset the phone to the factory settings everything works like a charm. Then I install all the apps that I need,and personalize the phone again,and everything works smoothly for a while,and then same story again. Becasuse of that what I said I think that problem isn't with SD card,'cause I alwas have at least 2GB of free space. In Opera I can open max two tabs. If I open 3 or more it tootaly freezes the phone for a few minutes (I set opera to store cash to the SD card, so I think that there is a read/write problem)
Is there some db or such file that maybe do that to me? I think, maybe there is some file that stores information about SD card (something like MFT on a PC) that needs to be repered? I have no other idea... Anyone had same or similar issue or idea how to solve the problem?
Thx!
p.s. I'm not using some cooked ROM for a few reasons. The phone is SIM locked, I don't want to loose my warranty in case if something goes wrong during flasing new ROM,and I'm quite satisfied with stock rom.

[Q] Apps Moved to SD Disappear fix?

I have a weird and it seems like a common problem too, i have found some threads about it but either they are a little different from mine or they dont have a real solution for it.
So yesterday i decided to download a bunch of games, i never used enough applications to need to move them to my sd, but since i downloaded a lot of them some started to get installed to the sd and i manually moved some of them too to the sd card. But while i was still downloading more apps, some of them started to show the android icon, and when i tried to run them they crashed. The weird part is that it was just some of them.
After that i tried rebooting my phone hoping that would help the phone to reload and see the apps, but that just made it worst since those, and some others went totally missing from the drawer. Is not because the launcher loads before the sd card is read because i already checked that.
So i went to settings>applications and discovered that all those applications are listed there but listed with their other name (dont know how to call it, but is like "com.developer.app" ). All of the missing apps are like that and i cant run them.
- I have formatted the sd using gparted, same behavior
- I have formatted the sd and the internal (sd?) with the phone
- I have done a factory reset with no luck
- I have runned fsck in both internal and external sd's
- The files of the applications are in the .android_secure folder in the external sd card "app.asec"
- The sd card is working (files music, everything else is working)
- I dont know what else to do, I want to be able to use my sd card to install apps
Thanks for your help
Simple Answer
Just Install Nd Run The Apk First Nd Play now simply move To SD
It Will Work.
Same Problem In Galaxy Y .
SolveD
Press Thank If I Helped
I dont fully understand you, but i think you are telling me to install, then run the app and then move it to the sd card, i did that to almost all of them (i was trying the games ) but that didnt make any difference. Thank you anyway!
looks like it was a faulty micro sd card switched to another one and problem solved
