I have had my phone over 28 days now so i can't exchange it or anything I just want to know if the following is normal... My Galaxy S2 reboots itsself from time to time, i have had it about a month and it has done it about 4 times in that time, does anyone else get this and why might it be happening? Also everyone I speak to on the phone says they can hear an echo on the line, I have tried this by calling my phone from my landline and there is an echo, when i say something loudly, it gets repeated back :/ - i was thinking it may be because of my case (Casemate Gelli) but would that be possible? It's also worse when the call volume is turned up higher. Any ideas? thanks!
