Take it back to the shop and get it fixed.
I've voided the warranty by putting custom firmware on it. Not only that, but the problem is accidental damage - it got knocked off my desk at work whilst charging and it seems to have buggered the charging port. When you plug it in now, it shows as charging but doesn't - in fact if you use the phone at all it will actually discharge. Normally I have to power it down now and leave it charging overnight now to get it to charge fully.
The plan was simply to put the original Samsung firmware back on it, send it to Mazuma, hope it passes their checks, then get a Nexus 4. The difference in price would be £30, if I go for the 16GB N4. I'm sure, broke as I may be, that I can rustle up 30 quid to have a phone that doesn't drive me mental. It does seem to operate perfectly normally anyway if you don't spend too long looking at it.
I appreciate that this plan is somewhat immoral.
