My Galaxy s2 keeps rebooting over and over because of sd card(special case) - Galaxy S II Q&A, Help & Troubleshooting

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 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.

LG P500 reboots and sd card

Hello,
I'm a new owner of a phone with android, since a month ago. The problem with my phone is that some time ago it started rebooting about 2 times per day (in some cases rebooting even I'm not touching it)
I tried removing almost all applications and didn't work (the first app was task killer since I read that's not needed).
One thing that may be helping the phone rebooting itself is that some times I see this notification: "SD card removed unexpectedly".
I have a 8gb class 2 card. But I tried with a 4gb class 4 card and same message appear. I tried formating both cards and didn't work.
Anyone can please help?
Best regards,
Pedro
and my P500 do a restart the card SD (2GB, which was from the market) and probably due to the firmware of the LG (it has a .10 b) so I expect the update from LG that fixes the problem
Sent from my LG-P500 using Tapatalk
thousands of us are facing this problem. LG are idiots to have released the phone with such a glaring defect.
But also thousands of us doesn't have any problems with this. It's really strange and you can not say, that LG is idiots - maybe everything works before on testing. Maybe some factory failed in collecting, maybe some wrong series of components... maybe.... who knows.
One think is true - they should face up to problems and not do, that nothing happened.
So the only thing that I can do, is wait for an software update from LG? (perhaps android 2.3 resolve it?)

I doubt whether this is related to software, since other phones don't face this issue. The phone has crashed several times at the end of a call, and I couldn't even press the disconnect button. When the phone doesn't even be stable and do the basic phone features properly, nothing else matters.
I also had this problem.
SanDisk 8GB cl2: reboot 2-3 times daily. Best 1% / hour battery.
SanDisk 2GB cl2: remount frequently. 1% / hour battery.
Original card that came 2GB(Samsung?):NO reboot,NO remount, 2% / 8 hours (night) battery!!!
My sd card didn't remove but the device some times start a reboot, and after a few seconds it enter on the phone (after the text ANDROID when i can see the desktop), when the phone signs he's mounting the sd, the phone goes on reset again and do this for several times, and i can't acess to the device. Some times he works normally.
I tryied to start the device without the sd but when he resets he still reset even without sd, so i don't think this isn't a sd question.
Some one else have this problem?
I update to the v10b by lg suite yesterday. I dont have the random reboot problem anymore for the last 24 hr. and I play pocket legend and like ever 2 hours the phone must reboot with the v10a. Now I am very happy with the v10b. no reboot for the game playing but i felt the graphic is little bit slower than v10a. and I am also factory reset my phone after update. So I can tell is it because the firmware or some software on the card or the root causing the reboot. But I am sure I am a happy pocket legends player. I am also using my old nokia 8g class 4 sd card with the original sd back up.
After I update to v10n, I've been runing android whitout rebooting and unmounting for about 125 hours (and growing).
I can say the software solved the problem because im using same card and I didn't factory either the phone or card.
My software version is already v10b by default but I'm still experiencing this "sd card removed" problem plus my phone also reboots it self rarely...
I've read threads about this problem and they recommend updating the software to v10e...
I contacted LG about this: It seems that the reboot bug is SIM-card related. Here in germany, Eplus (and their retailers) SIM-cards seem to be affected.
hi after updating to 2.2.1 v10n i dont have sd card error and reboots that often but sometimes i cant see the apps installed on the sd card. has anyone noticed this too? after remounting the sd card i can again see the apps and can access them but it keeps on appearing and its quite annoying! plz help!
i have both problems rebooting sd card and disappearing apps
i also have v10n

Based on my experience, I'd say the reboot is triggered by the unexpected sd card removal after moving apps to the sd card. Until I've seen some working prove, I'd assume the idea with SIM-cards is just another theory.

I have the phone from late october and experimented a lot with this problem.
In my case it only happen if I move some apps on the sdcard, if I don't move any apps on the sd card, no reboot happens. Also it seem more frequent when data connection is not "stable".
Some user reported they were able to turn around the problem keeping wifi on all the time, but it is a solution I like
In the last couple of months I used the phone with all the apps on phone memory and never had the problem again...
I got this phone a week ago and it's been rebooting ever since.. I even updated to v10f and now it says something about the SD Card after reboot and the SD card wont work after that.. so I have to reboot manually for the SD card to become active again... this phone is nothing but headache... but I'm still happy with it..
Do custom ROM's also reboot randomly?
you need atleast a class 4 sd card, im using class 4 16 gb sandisk. Absolutely no problems at all.

[Q] Reboot automatically

Hi Guys , I have a problem with my SGS II , it reboots itself automatically , and I notice that the problem started since I updated to firmware 2.3.4 XWKI4 via Kies ( before 2.3.3 ) and never been rooted , and I don't want to root it just yet , so anyone have any idea what causes this problem and any solution ? please share , thank you .
If you want to stay on stock maybe try factory resetting.

-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 :
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!!!
Hi Thank you for your advice , I've tried moving all apps to phone from SD an everything's work well no more auto reboot , Thank you

(A) Install problem to SD Card

Hi
I have the problem that i cant install some apps or update them.
In the market i get the error while install to SD card.
this issue was not at any app but some.
I Tried recovery from CWM not working.
Clear any Cash Dalvic cache formating sd and external sd card. I get the same error.
I Installed an Original Rom and set Re-Partition but i get the same error with 2.3.6.
I solved my Problem with a pit while flashing 2.3.6 with Odin.
So i used the Original 2.3.6 3 files Version and set the Pit in the Attechmend.
Re-Partition set and the problem was fixed.
After that i installed a custom Kernel with Odin and Installed Omega 1.1 ICS in CWM all my problems are solved.
BUT NOTE YOU LOOSE ALL YOUR DATA
You don't have to loose all your data you just need to back it up properly first
yes but nobody can tell you where the problem come from.
Maybe you backup your problem.

Whats with the attitude? It doesn't matter what problem you have you never have to lose all your data... It takes 30 mins to set up a phone again from stock to being identical to how it was...
with this issue i reinstalled 2.3.6 and have the same issue. clear you can backup but maybe its not working after that.
there are a lot of people woth the same issue. and wipe didnt help!

when you dont have this issue its hard to explain.
Unnecessary post. Deleted.
I have had this problem with any ICS ROM I installed on my SGS II. I thought of simply unmounting the SD Card, try installing the Application or an Update for the Application, it always worked. Yes it does sound like there is too much to do each time you try installing a new app which will fail due to the mounted SD Card. But if the problem is unknown, and flashing a file to solve 1 problems breaks other two functions is a bigger and bitter problem, might as well try this simple solution.
Good Luck
For me it isn't the "sd-install" problem that occoured with cf-root since ICS 4.0.3 XXLPB.
But maybe it's one of the things that caused the problem.
Flashing back gingerbread, even a 5 part FW did NOT solve the problem, so i have a bad feeling about this...
First i thought the file "vold.stab" in folder "etc" that is responsible for the mounting, is just messed up.
But this file SHOULD be overwritten when flashing a 5 part FW... or not?
So i think my hardware is damaged...
But i never had any failure while flashing... the problem just happened suddenly...
Just unmount sd card and install
Sent from my GT-I9100 using XDA App
Please read my previous 2 posts. It's not this problem.
The last resort to force the phone to use the internal card again should be to flash a 5 part official FW while having no external card inserted. But even after that procedure it still don't recognizes the internal card for apps...
It uses the external only. When having no external inserted, i can install apps only to phone storage. It's similiar to the known ICS Beta problem, but with a card swap in addition. And it's permanent. Flashing the Gingerbread FW that was on my phone when i bought it also didn't fix the problem.
Normally it's like this:
Phone storage, about 2GB, path: /mnt, for apps
Internal SD, 11.5GB, path: /mnt/sdcard, for apps and data
External SD, card size, path: /mnt/sdcard/external_sd, for data only
For me it's like this now:
Phone storage, about 2GB, path: /mnt, for apps
Internal SD, 11.5GB, path: /mnt/sdcard, FOR DATA ONLY
External SD, card size, path: /mnt/sdcard/external_sd, FOR APPS AND DATA
It just happened suddenly about a week ago. And i got several problems related to this.
Sorry. I was in a hurry and Didnt read the post.

[Q] Files randomly gets deleted. (SGP 5.0)

Hello everyone! This is my first post in this forum but i've been using this forum for months now..
Anyone knows why my files are getting deleted randomly and placed in LOST.DIR? Files are still in their locations but their size is 0.0kb.
They somehow go to LOST.DIR and become unreadable. Is it a faulty Micro SD card or my Player 5?
My SGP 5.0 is using:
PARANOID ANDROID v2.57.4- March 07 Update
Mercurius v5 Kernel
This problem also happened on Stock GB ROM, anyone know what is happening? any help is much appreciated.

This is not any related to our very good device, it is android behavior. (good anyway)
Thanks!
But Google didn't help. I know what LOST.DIR is for.
This doesn't happen only on startup, sometimes it's hours or days before files get deleted.
I also do the whole safety remove thing on my PC and SGP 5, and let it finish checking the mem card.
There's also nothing wrong with the files, my iPad and blackberry have the same files in them but don't get deleted.
I know the SGP 5 is a good device, i have one...
If it's android behavior, why is it wiping half my memory card's worth of files for no reason?

Try backing up your files and format

Already did that several times now but it still happens.
I've formatted my SD card, restored it to default, de-fragmented it, full factory reset my SGP 5. It still happens.
Maybe it is a faulty SD Card?
Also, this happened twice already, after copying files to my SD Card from my PC, safety removed it, my SGP said "broken sd card, please reformat", even my pc can't read the card...
It must be my sd card that's causing the problem and hopefully not my Player, what do you guys think?

Fine,
You may Check for some days with another ext Sd card to discriminate this case.
Do you have backup application running or some auto cleaning apk like "forever gone" starting at certain times?

No cleaning apps... I'll try with a different SD card... Thanks for the help.
It happens to me as well. I assume it has something to do with the Galaxy Player (or the SD Card). If it doesn't happen, the SD card randomly gets damaged.
so i bought a new SD card, a Kingston Class 10 32gb, using it for more than a week now and so far no file deletion. I think it's because i was using a cheap SD card, a TDK 32gb Class 2... if the problem happens again, it must be Android's check disk that's causing it.

[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
