Help S2 keeps rebooting

Mine's been doing the same. Just upgraded firmware to KE7; crossed fingers that'll solve the problem.

How is the KE7 working for you? I live in Sweden and need it for the same reason and I really hope it will solve the rebooting problem. But as you understand the upgrade is not yet released here. Anyone heard when it will be available for everyone?:)

Had it on KE7 for several days now and only one random reboot, and that was when I was absolutely caning the processor, doing about 5:cool: things at once (including downloading, online, moving a large file in My Files, etc.). Don't think battery life is any better, though.
Oh yeah, calendar has stopped working! All my appointments are still there online, and on my Galaxy Tab calendar, but the SGS2 calendar (for the same gmail account) is now empty!

I have had the GS2 for about a week. I have not made it through a day without having to pull the battery becuase it froze. Today, I had my first random reboot.

so torn, becuase I swear, this is the greatest phone I have ever used.

Would suggest a factory reset for this and check the firmware via Kies. I personally have the odd problem but it ain't that bad. Can you narrow it down to any particular app you may be running?

I have no idea what this means though! Note I have had the issue with and without the SD card inserted and my USB port was not being used at the time.

Hi people,
I'm fairly sure I've figured this out and come up with an easy fix :)
First the cause:
Poor fitting battery, made worse by a badly designed micro-SD slot position.
When you have an SD-card fitted this can push the battery away from its contacts. I found my battery had about 0.5 mm of movement up and down. Every time my phone reset it was when it was in my pocket and subject to movement.
Riding my bike to or from work.

The fix:
Lovely and simple just place a bit of paper placed under the bottom of the battery to push it up towards the battery contacts.
I used a UK lotto ticket (loosing one) it was just the right thickness to stop the movement. (Tesco till receipts work just as well.) Tear your lotto ticket in half then half again, wrap your quarter ticket over the bottom edge of the battery, push the battery into the phone and check for movement. You may have to double up, I found just one layer was enough to stop the vertical movement.
fit the cover and turn on your phone.

Enjoy.

How long has it been now since your last 'random reset' after using your method?

I was thinking this was a software fault with android 2.3.3 because I know on my desire after flashing to 2.3.3 oxygen rom everyone was having random reset issues until someone fixed googles code up in the rom and now everything is fine.

This looks to be a different problem to the one I have experienced as I have the issue with and without an SD card inserted. Will be interesting to see if the above helps any of you guys out though :eek:

In the meantime I have raised the issue on mine to Samsung direct - my thread on the Android forum at Issue 17365 - android - OS rebooting on Android 2.3.3 - Android - An Open Handset Alliance Project - Google Project Hosting seems to point towards the issue being with Samsung rather than Android.

I think you could be right, or it could be a proper hardware fault, my phone locked up again today despite my paper battery fix. A phone that runs cold for hours shouldn't suddenly lock up and get hot, mine gets hot in the top left corner. I wonder if its due to the camera firmware I flashed. No matter its getting sent back on Monday for a replacement. the online store have actually arranged for a courier to collect it :) at no charge to me.

Tried to get Samsung to look into this but they just kept coming back with the generic 'take back to the shop to have it reflashed'.

This ain't gonna help since I had the issue with the original firmware and also the latest. The operator was also adamant that the reflash would fix the bug. Couldn't convince her of the difference between corrupt software and buggy software oh dear :rolleyes:

Will just have to hope a future update sorts this I guess.

Hey folks, my S2 has done this as well. It seems to do it when i tap an app and it doesnt matter which one i dont think. Last time was when i went to open Twitter and the screen went black and i got the samsung start up screen followed by the 02 welcome message.

I have tried taking battery out and putting back in to ensure its in firm, ive rebooted it myself every night in case its the RAM getting too clogged even though i clear the RAM regularly.

I have an appointment with 02 tomorrow to get this sorted so will report back when i know whats what. Although them replacing it would be good, it would also mean i have to pay another

I have been to 02 this morning who advised that it could be the following things or combination there of:

  • An app or two that conflict
  • An issue with the software
  • A problem with the RAM
  • Another hardware issue

Up until today I have seen it suddenly reboot itself after tapping an app 4 times with a gap between each even varying from a couple of days to a week. But today I have 3 incidents. The first was 5 minutes before my appointment. The second was on the way home and the final one was a few hours later. I have now booked myself in for another appointment. Does anyone think if i request a replacement it will happen or will they force the issue to be looked at by sending it away?

I came here because I have a very similar issue. Spontaneous reboots that happens when I listen to music. Although I usually do this while doing housework or walking or something so it's possible it's the battery shifting slightly but I figured it was something with the music and/or music player. Just using the standard Android music player.

Will try the paper solution to see if it fixes it and will report back.
