Help Crashing issues.

[Hyperbolic]

Hi guys,

I'm suffering some pretty severe/frequent crashing problems with my Galaxy S2 (GT-i9100, SIM free) and I'm struggling to diagnose it or see a way forward.

I'll be using it for general use (i.e. texts, Facebook, web browsing etc.) when suddenly it just gives in, crashes and remains turned off.

Often (but not always) on turning the device back on, it'll have forgotten the level of charge in the battery and believe it is "critically low". This would lead me to believe that the battery is broken, but when I plug it back into the charger, the battery level returns back to the original level (so if it was 80% before the crash, the charge will return immediately to 80% after connecting to the charger). So clearly then, the battery is holding it's charge, so I don't think the battery is at fault.

This brings me on to the software (running Samsung's stock Android 4.0.4). Just before the crash, the notification bar at the top of the screen will show that the signal will crash, as will the wifi. Then obviously the whole phone crashes. It doesn't seem to depend on whether the phone's wifi is on or not. Could it be a memory issue?

I don't think a factory reset would be at all useful, so is it a case of completely resetting it with an older version of Android which might be more stable on this device?

Hope you can help!

Thanks,

Hyperbolic.

Hello and welcome to Android Forums Hyperbolic!

Sorry to learn of your problems. Strange that you do not think that a Factory Reset would be useful as this is why it is included in Android.

Perhaps a read through, "Firmware update problems... what you can do!", and a comparison of some your symptoms with those mentioned. Also contained are instructions on how to re-flash firmware if needed.

Grab a coffee and have a read through.

First, when you say it crashes, exactly what happens? The screen freezes and will not respond? The phone just shuts off (not shuts down, but simply goes black)? Does it ever throw an error message?

It certainly sounds like a battery or charging circuit issue. Does it ever do this while it's plugged in?

If the problem is hardware related, i highly doubt any reset to a previous version would help. The simplest test would be to replace the battery and see if that fixes it.

The phone just seems to have become steadily more unstable as it's moved up to newer version of Firmware, which is why I thought a factory reset would be useless. I'll give it a try though, I've got nothing to lose after all (the phone is as good as useless to me at the moment!). Thanks for the link!

When it crashes, the phone screen becomes unresponsive for a split second before it just 'shuts off' as you describe it. Normal procedure to then just restart the phone, although as I said, often with a lack of charge which has disappeared against all the laws of physics :stupido3:. It never gives out an error message unfortunately no.

I can't say I've tested it whilst it's plugged in particularly, but I don't seem to remember it being the case. Maybe something to investigate further, thank you.

Thanks for you quick replies guys, a great help.

Hi again,

Decided to investigate the battery to see if that was the fault, it appears to be the case. On closer inspection of the battery there's actually a slight deformation in it (god knows how that has happened, heat I presume). Whilst running through the mains it remains stable.

Looking for a replacement battery is proving a little difficult mind, some 'genuine' parts being sold on Amazon do not look legitimate in the slightest. Is there any recommended sites which you could direct me to (there's Tesco, but they want
