Question Galaxy S2 turns off

Hello

I have a galaxy S2 already for several months.
The last weeks I have seen that my phone was switching off and on automaticly.
Do anyone have the same problem?

regards

Pierre

There can be many causes. Problem with installed apps. Defective microSD card. Clashing of firmware due to upgrade of firmware.

Mind letting us know what you did before the problem occur? What recent apps installed, if you did an upgrade... etc.

It's not the first time that I have seen it, but in the past I tought thay it was because the phone was in my pocket.
Yesterday the phone was on the table neer of me and he was starting up again without any contact. Now I'am shore that its not because the phone is in my pocket but starting up for another reasen.
I thik I installed the last months more then 5 or 6 applications.

Try uninstalling the apps one by one and then reinstall to see if can eliminate the problem app. List the apps. Maybe someone of the forum have the same issues with the app.

Did you do a firmware upgrade?

Cool

It's still the original firmware.
The problem is that it's happening not every day. The last time it was one friday last week

Did the reboots happen after you did the firmware upgrade? Did you do a factory reset before upgrade?

I am facing same problem since last last week.

Today I noticed that my battery was 81% charged when my phone automatically switched off
Battery Usage was
56m57s on battery
Android OS 55%
Screen 15%
Media 7%
Android System 7%
Cell Standby 4%
Maps 4%
Phone idle 3%
Android Core Apps 2%
Facebook 2%

I updated my device to 4.0.3 version last week.

I don't know whether this problem is due to
1. NEW update 4.0.3 or
2. I installed any wrong apps from market
3. Any software problem
4. Any hardware problem

PLEASE GUIDE ME SOLUTION

I have recently purchased a used Samsung S2 LTE running ICS which would turn itself off automatically several times during the day. Turning on the unit would then require a long hold on the power button or removal of the battery. I had tried several possible solutions including wiping the partition cache, cleaning the battery contacts, and completely discharging the battery, but eventually determined that the problem was with my brushed aluminum slim casemate.

I suspect the tight fitting case would twist the cell phone causing the battery to have a poor contacts and the unit would shut down. I haven't had any problems since I have removed the case.

I had the same problem - and did what was recommended. The system apps you have installed are clashing
the same can happen on PCs. Any App games do not affect.
Delete any system apps you had prior to this happening. E. G. 2 virus protections will clash.
I hope this helps. I did this for mine. Game Apps should be OK.

Put a piece of paper (double if necessary) at the bottom of the battery to force the battery contacts and the handset contacts together. Worked for me!

Default galaxy s2 shuts off

Re random shutdown.It makes the galaxy s2 useless as a phone a you cannot be sure it is turned on.I think time for a class action law suite!! The Samsung repair in Thailand shop can't get it right.Any lawyers interested in helping us recouping our money or exchanging for a product that works?

I had exactly the same issue with my gf s2 phone. I ended up getting a refund on it and bought her the nexus 4.

I reset it back to factory defults and ran tbat. It still shutdown and there was no way I wad paying for a phone that kept shutting off. Not much help, I know but the nexus 4 was the same price and she prefers it.

Hi all,

I have commented on another thread, but thought I would leave something here.

Basically, I am on to my second S2 in two months.It has been for repair to Vodafone and Samsung.

I was told by Vodafone today that Samsung are aware of the issue. When they receive the faulty phones, they test them to see what the issue is. Sadly, because it's the software, they can't do anything until they find out exactly what the issue is!

I am so disappointed because it is a great phone. I have written a letter of complaint to Samsung and am really hoping Vodafone might exchange my phone.

Good luck with it - sounds to me like there is no solution.
