Samsung Galaxy S2 keeps switching off and apps crash...

Anonymous — Tue, 29 Jan 2013 12:12:52 GMT

Hi,

Has anyone had this problem with Samsung Galaxy S2 - basically is keeps switching itself off.

It stays on while it's plugged in, but 5 minutes after removing the charger, it switches off without warning.

As well as that, the apps keep crashing. Besides the internet (which was pre installed on the phone) and GMail, none of the others work. Clicking the icon just brings on a black screen and then a crash report.

And finally, it's wiped all of my contacts.

Back up what you can on the phone and do a factory restore. Hlod down volume-up, home and off/on switch simultainiously until you get the root menu. Use the volume button to scroll to clear cache petition then reboot.

If that doesn't cure the problem, use the same method to then factory reset. Be careful what apps you put back on there.

That seems to have worked! Thanks so much.

Actually, it's just sorted the apps. The phone is still powering off.

It could be an app causing the problem or possibly a software problem. Remove the apps one by one to see if that sorts it, you can always add them back. Make sure you haven't installed any battery saving apps as they can cause all manner of problems.

Unfortunately you may need to send the phone for repair if the above doesn't work.

Should I only remove apps I've installed from the Play Store, or do I take off the pre-installed ones too?

The stock apps should be ok, just the ones you have downloaded.

Turning off could be a faulty battery if you still have the problem without any apps installed.

I tried it with the apps uninstalled and it switched off mid-way through a phone call after dropping the previous one.

It may be just a battery problem, but as it dropped the calls a message appeared on screen about the radio, and on the second call it switched itself into flight mode before powering off, so it's making me think it could be something else.

Yes, sounds as though it could be the modem that is failing. You could try reflashing the firmware or send it in for repair.

How would I reflash the firmware? Is it a simple process?

Re: Samsung Galaxy S2 keeps switching off and apps crash...

Yes, very simple and much quicker than sending phone in. I can't guarantee it will fix the issue but it will be the first thing that the repair team will try anyway. To start off I need to know what firmware you are on then I can direct you to the relevant downloads. Dial *#1234# into your dialer and let me know what it says. You can PM me if you prefer to do so.

OK. Go here and create a free account, then log in http://www.sammobile.com/

Then go here and download the firmware http://www.sammobile.com/firmware/?page=8&view=4914

Then go here and scroll down to "additional files" and download where it says "flashprogrammes" http://www.sammobile.com/firmware/?page=3&model=GT-I9100&pcode=O2U&os=1&type=1#firmware

If you have not already done so you need to install the drivers (also on the above link under "additional files").

Let me know when you have done all this.....

I've just downloaded all of those files now.

Edit: On opening the folders, I see some .exe files. I only have a Mac, so I'm guessing this won't be straight forward!

Doh !!! Try this instead http://www.samsung.com/uk/support/usefulsoftware/KIES/JSP and choose the Mac download.

Ok, that's downloaded and installed.

Hopefully now you can open the Kies programme and connect your phone to your Mac with the data cable. Wait a while for the drivers to install and you should be offered an update to your software.

Annoyingly, Kies keeps crashing before it registers that the phone is connected.

Kies is quite fussy, which is why I went a different route with you originally, however, your only hope is to persevere with Kies or send phone into a repair shop. Try removing and reinstalling, rebooting PC, connection troubleshooter etc....

Sorry, not much more to add...
