Hello, I need some advice before tomorrow please! My SGS3 screen went blank yesterday, phone still works but can see nothing. O2 are kindly replacing it hopefully in the morning but I have just realised that someone, with the right know how could potentially access the various apps/financial data before I get chance to change every sodding password. I'm sure this is unlikely but would rather be safe than sorry, so is there anyway I can reset/clear down the phone before I hand it over to the courier??? Thanks in advance....
