[Galaxy S II Q&A, Help & Troubleshooting] remics:
Actually I was able to run some more in depth testing this weekend. It seems my phone is very unstable when I have my Ms Exchange server client set to update via push messages AND I have a card inserted in the phone.

1. SD in phone, Exchange account disabled (or set to manual) - no restarts

2. SD not in phone, Exchange account enabled (with push notifications) - no restarts

3. SD in phne, Exchange account enabled (with push notifications) - random restarts

4. SD not in phone, Exchange accoutn disabled (or set to manual)- no restarts

It seems that the default exchange client can't handle having SD cards in the phone when it is using push messages ... which makes no sense to me.

Also related to the cards, I have tried all sorts of formatting (computer full format, computer quick format, phone default format) it doesn't seem to change the behavior detailed above.

Can anyone else confirm my findings ?

For now I am forced to run with manual Exchange sync (or with no SD card).
[Galaxy S II Q&A, Help & Troubleshooting] :
A couple of months ago I was listening to music using the stock music player and I noticed that the phone will reboot if I play and MP3. I tried playing some OGG's and only one out of, like, twenty crashed. I switched to Winamp and it's much more stable now, however it restarted twice this week. I'm annoyed. I don't want to look like an idiot to the CPW staff with getting my phone replaced every now and then (last time I got it replaced because it wouldn't stop downloading data... also, the screen is "gorilla" glass but it's softer than my bloody pillow... My HTC Hero never got scratched after like 2 years of clumsy usage. This flimsy piece of "glass" gets scratched after a month...).

After my S2 was upgraded to 2.3.5, it got the reboot issue.

I used Dolphin HD but I uninstalled it now. Hope this solution works.

And I lose reboots when I upgrade to 2.3.5
[Galaxy S II Q&A, Help & Troubleshooting] Zippodk:
I had the same problem in months now. Running 2.3.5. restarted without me using it. I could just hear the restarting sound. I went trough all of you'r suggestions but nothing helped.

Installed AVG antivirus off the andorid marked. I updated it in settings and ran the scan. Turned of what AVG asked me to do in settings. Not a single restart in 2 weeks.

I hope this helps others.

Same problem... fixed mine! Hopefully will shed some light!

My S2 started the 5 second reboot this morning while using the stock music player. I've had the phone for 2 months now without this issue. Yesterday, I was using Album Art Grabber to place some artwork on a custom track that I made. I told this app to use a picture from the sd card. The music will start fine... but when the screen goes to sleep it reboots. I can play all my other music with no rebooting. So I opened the app and got rid of the artwork from the sd card and now it does not reboot when I play it. The weird thing is that I had a play list that contained a mix of music that did and did not have my custom art work from SD. When the music that did not have the artwork from sd was played in the play list, it would reboot the phone... but not when it was played outside the playlist. I would say that it has nothing to do with the music player and would lean towards OS obtaining sd card info followed by sleep after reading everyone's posts. That's the one common denominator.
[Galaxy S II Q&A, Help & Troubleshooting] R3troMan:
Have restarts since Android 2.3.4. It have the feeling the number of restarts has increased with the version, from 2.3.5 now running 2.3.6. With this version, I experienced 2 or 3 resets each day. It would reset itself after lying on my desk, untouched, for hours. But I think this has nothing to do with the evolution of Android versions, but with the number of apps installed on the phone. The higher the number of installed apps, the more likely one of them apps wants to do 'something' with the 'external' uSD card, even if the phone is configured not to use the uSD card for apps. See what I found out:

Despite the fact that I don't install apps to the 8 gb 'external' uSD card (I exclusively use this card for MP3's), it seems the phone is putting some files there anyway. A folder ".android_secure" was on the SD, containing .ASEC files that were related to apps installed on the phone.

I removed the uSD completely, resulting in certain app icons (the ones that had .ASEC files on the uSD) being set to the Android logo. When activating them, the error message 'app is not installed' (or something similar) would appear. Also, .ASEC files for Live wallpapers were on the uSD; those wallpapers were completely gone (not selectable in the settings->background menu) from the phone.

Then, I re-downloaded these missing apps and backgrounds from the Market and re-installed them. Ran the phone for 24 hours now and.... the phone did not reset itself!

I will keep this situation for a few days and see what happens. If I still get no restarts, I will put back in the uSD card, run some apps and check the content of the uSD again. Will it contain the same .ASEC files (which I presume are now on the internal phone storage somewhere)? And will it start to restart again?

I'll come back to this, keep sharing your experiences please.

I have the same problem my Galaxy S2 restart its self I tried many solutions and its doesn't work. I have SD card and I installed too many apps and transferred some on my SD card.

When I pulled out SD card from my device it working fine that mean the problem is from SD card and The exactly problem is from apps that installed on SD card because when I format it their is no problems but when installing apps and moved some to SD the problem starts again.

My device firmware is JPKJ2 with android 2.3.5 I didn't give up. I tried deleting orginal apps like Social hub and so on, the problem still there. then I deleted cache and Dalvik cache, first time work fine but after I restart device manual the problem comes back.

Today I tried flashing old firmware JPKI1 its with android 2.3.4 and the problem gone. I installed too many apps for testing then their is no restart problem. I restart it manual to be sure if every thing ok and YES the problem GONE that mean its a software problem for me at least.

I hope from developers to find a fix for new firmwares that cause this problem.

Thanks

I have almost all of the apps, plus many more, and since leaving Bell stock (2.3.3) my reboots are gone. Im now using some firmware for Poland (2.3.5). I think its a bug in 2.3.3.
[Galaxy S II Q&A, Help & Troubleshooting] R3troMan:
[/COLOR]Almost 48 hours now, not a single restart. 100% that uSD is the problem. Just one more day and I'l' pop the uSD back in to run some more tests.
[Galaxy S II Q&A, Help & Troubleshooting] stragulus:
I have upgraded the stock firmware I had on it since may this year (2.3.3) to 2.3.6 yesterday, and it's rebooted spontaneously 3 times since then already. Before that, it rebooted twice since may(!). I never rooted the device or installed anything custom on it since I got it.

I'm copying your experiment, though I just unmounted the SD-card from the settings menu, rather than physically taking the card out. Should have the exact same effect.

I'll update here as well.
[Galaxy S II Q&A, Help & Troubleshooting] zkyevolved:
Hey guys, I'm having the same issue. Sometimes it's in my pocket and sometimes it's just on my desk, and I hear the Samsung chime and it's restarting. I have a 32 gig card. At the moment all I've done is moved the files off the SD card (apps at least) and we'll see. Hopefully that'll fix it, although that's no real solution.

I'm thinking of downgrading the OS. I never had this issue with the last OS I had. So we'll see. :)
[Galaxy S II Q&A, Help & Troubleshooting] SaneinOne:
Dolphin HD and possibly apps installed to SD were the cause for me.
[Galaxy S II Q&A, Help & Troubleshooting] stragulus:
Nope, this didn't do the trick. Rebooted in the middle of the night again.

I think all these tricks we're applying are not fixing the root cause, but are just decreasing the odds of reboots happening. The pattern seems to be wifi-usage + longer standby time.

Samsung definitely screwed something up though, as many people are suffering from these reboots since 2.3.6. Before that they occurred as well, but not quite as frequently as they do since this release.
[Galaxy S II Q&A, Help & Troubleshooting] R3troMan:
>>I think all these tricks we're applying are not fixing the root cause, but are just decreasing the odds of reboots happening. The pattern seems to be wifi-usage + longer standby time.<<

Not here. I get reboots also when I'm not connected to wifi. For now I know 100% sure that card out = no reboots. When I put the card back in, it immediately gets those ASEC files (the ones I deleted before) back on it. In less than 12 hours I got back to having restarts again...

No reboot problem after 3 days from downgrading firmware to a rom with Android 2.3.4

and even after restarting it manual many times for testing then no reboot problem.
[Galaxy S II Q&A, Help & Troubleshooting] R3troMan:
I think restarting it will lower the chance of a reboot. However, I noticed 1 or 2 reboots with 2.3.4, and really start noticing it with 2.3.5. So it could be that my reboots with 2.3.4 were coincidence (I got it out of the box with 2.3.4, so I installed all kinds of funny stuff trying out my new toy), and that the problem was introduced with 2.3.5.

Any more on this?
[Galaxy S II Q&A, Help & Troubleshooting] stragulus:
Besides unmounting the sd-card, I have also done:

* Disable samsung apps notifications (settings->applications->samsung apps)

* Disable wifi before I go to sleep

The only crash I had after just unmounting the sd-card was a reboot in the middle of the night. I think disabling wifi before going to sleep fixed this.

Haven't had a reboot since (2 nights, 3 days)
[Galaxy S II Q&A, Help & Troubleshooting] dbuckham:
I'm using the AT&T Samsung Galaxy SII and I get the random reboot/bootloop error too. The first month I had the phone I had no SD card and still had the reboot - bootloop issue. I did get a 16GB class 10 card the other day and installed it. Still getting reboot/bootloop issue. What I have noticed is that turning the WI-FI off right after the phone reboots I can stop the bootloop. It appears to be connected to network/wi-fi connectivity. Since many apps use wi-fi/network an app may be causing the reboot/bootloop when it doesn't have a significant or appropriate signal. I live in an Edge network area (not even 3G!)...but I've still experienced this issue in 4G/LTE areas as well. It's really anyone's guess.
[Galaxy S II Q&A, Help & Troubleshooting] R3troMan:
Hi there,

Could you point out how to do a downgrade?
[Galaxy S II Q&A, Help & Troubleshooting] jevermeister:
Affirmative,

I have reboots every 25 or 26 hours so I restart my phone manually before going to sleep.

But come on, a 500€ device with this kind of s***ty behavior?

I reflashed 2.3.4 via odin but it does not doe the trick, now I need a 3. part firmware. Want to try some repartitioning.

[Galaxy S II Q&A, Help & Troubleshooting] horrocks:
I also have (had I hope) the random rebooting problem after I installed 2.3.6, but, I do not have an SD card installed. I called Sprint tech support and they recommended a hard factory reset after an over the air update. I reluctantly performed this reset and it took about an hour to get everything back to where it was before, ie apps, etc. I will monitor and let you know if this worked for me.
[Galaxy S II Q&A, Help & Troubleshooting] horrocks:
Still rebooting after factory reset. Must be a 2.3.6 problem.
[Galaxy S II Q&A, Help & Troubleshooting] klashosh:
Ive never had an extra sd-card in my sgs2 and ive never had a random reboot so i really think there is a coincidence between using sd-card and reboots. Ill be using a sd-card after the christmas holidays so we'll see if i get any reboots then.
[Galaxy S II Q&A, Help & Troubleshooting] essamco:
its really bad problem

I transfered apps to SD card with a lot of new roms which comes with android 2.3.5 and 2.3.6

all results gets reboot problem, EVEN WITH beta rom of icecream sandwich the reboot problem hapened wtih it.

All developers please try to find fix for this problem
[Galaxy S II Q&A, Help & Troubleshooting] essamco:
Until now ther is no fix for this problem!!!

Only by downgrade to rom with android 2.3.4
[Galaxy S II Q&A, Help & Troubleshooting] jevermeister:
I have a original 2.3.4 rom and I have this problem.I reflashed the rom via odin flashed a 3 part rom based on 2.3.4 but nothing helps.reboots every 26 hours. i will return the phone in the new year. I just smashed it to the wall in a very angry mood. :-(

Nils
[Galaxy S II Q&A, Help & Troubleshooting] dragon135:
So here is my story:

My sgs2 always reboots itself 3minutes after booting. I know the cause is because I have 400+ apps installed.

This problem happens after upgrading to > 2.3.4 official ROM. In 2.3.4 or lower is OK. So I stuck with 2.3.4 ROM now.

After reading this thread I thought maybe it is caused by my external SD Card. Guess what? I remove external SD, flash 2.3.5, no reboot problem even after several times power off on. I put external SD, reboot problem happens after power off on 2 times.

So now I save external sd data and format my external SD and. I'll try put external sd after restoring the data.
[Galaxy S II Q&A, Help & Troubleshooting] essamco:
I think you have different problem than our problem.

our problem comes after transfering apps to External SD Card (new Roms with Android 2.3.5 and 2.3.6)

I hope from developers to focus on this issue because some day you will need to transfer apps to External SD card.
[Galaxy S II Q&A, Help & Troubleshooting] Dexonja:
Rofl wipe that i think 85-90% apps u dont use...
[Galaxy S II Q&A, Help & Troubleshooting] essamco:
This is not the point. The question is why this problem occurred.

Why when we move apps to SD card reboot problem comes back.
[Galaxy S II Q&A, Help & Troubleshooting] horrocks:
I believe I found my rebooting problem. Around the same time I installed 2.3.6, I also got a new pouch for carrying the phone. I do not currently have a case on the phone and I am pretty sure what is happening is the power button is being pressed and held causing the reboot. I even got the android screen sometimes as you would when you press the volume up and power at the same time. I will install a phone case to protect the button access while in the pouch. These things can be bizarre but it sure feels good to find the root cause.
[Galaxy S II Q&A, Help & Troubleshooting] dragon135:
Now I come at conclusion that reboot problem will eventually happens in the future after u run out of internal storage for apps.

This force u or android os to move/install apps to sd card, the more apps u install the more chance it is installed in sd card and chance of reboot becomes higher.

This bug happens in version greater than 2.3.4. Sd card brand/size/class does not matter.

So sad, I am forced to stuck with 2.3.4 cannot upgrade because of this reboot problem

Is there ways to report this reboot by sd card problem directly to samsung?

I think this is a very big issue that this phone cannot handle apps in sd card correctly.

It is shame that this side effect is not detected by their QA for long time.

Are we on the same topic here. I think the reboot problem in this thread is when u have some apps installed in sd. If external sd is removed, no reboot.

If u have another 'ordinary' reboot problem, there is sticky thread about that. Usually it is caused by changing rom or kernel without wipe or factory reset.

It seems this issue is not related to programs on SD card, I removed the card and still get these reboots. I am now testing with Wifi off, there is a good chance it is wifi related in the latest rom.

yep, same here it is definitely WIFI related, im on 2.3.6 and when im connected to wifi the phone keeps rebooting 2 or 3 times a day if wifi is switched of it just works fine, is it just firmware related i mean does it happen to older firmwares as well, should i downgrade or any known fix?

Why don't you put a few albums on the phones internal memory, take out of the SDcard and then use the phone for a few days sans SDcard and see if you still have problem. If you still have problems, come back and post something on this thread, if you don't have any more problems GG you win go and return the SDcard.
[Galaxy S II Q&A, Help & Troubleshooting] stragulus:
I have now seen multiple confirmations from another forum which indicate that, for those with 2.3.6 and the reboot problem, most reboots do go away by unmounting the sd-card (no need to physically take it out). It may still reboot on occasion, most apparently after long idle times with wifi enabled. These can be prevented by turning wifi on and off manually when you need it. Then it's rock stable.

So yeah, definitely sd-card (mostly) + wifi (less severe but still bad) related.
[Galaxy S II Q&A, Help & Troubleshooting] isostars:
@stragulus im just testing right now for about 4 days with wifi off and no reboots at all as soon as i turn my wifi on it reboots randomly, i got a 16gb sd card and all is working fine without wifi turned on, so i think it is really a wifi connection issue and have nothing to do with the SD card, there could be problems if you got programs installed on your external sd, so i really hope samsung will take note and bring a fix asap.

I dont think it will solve the issue, they always suggest to do a hard reset when they dont know how to fix something, i just flashed my firmware so my system is fresh and clean and i got the reboots when i turn wifi on, so i really dont think a hard reset will fix sumthin.
