Love the phone, having a few issues though unfortunately. The over heating as others have mentioned is a definite worry. It's got really hot at times while I've been using it the more worrying aspect for me however is how hot mine gets while charging, has anyone else experienced this? Mine got so hot the other night it woke me up when I accidentally rolled over on to it.
The second problem I'm having is crashing. It seems to be crashing fairly regularly. This may be linked to the over heating I'm not sure. Seems to crash more often than not when I'm playing a game though there has been a handful of occasions wherein it's crashed while I've been using the market.
The third & thankfully final issue is the battery life. I think I might have just got a bit of a suspect phone because my battery is appalling. I've got friends who also have s2s & most seem relatively pleased with the battery life. Unfortunately for me mine takes the piss! The battery is yet to last for a full day, I don't run gps or wireless unless I need to, I use juice defender & have all my settings set to the most economical setting i.e auto adjusted screen brightness, no vibration, low sound etc has anyone else had this problem or have I just been unlucky & ended up with a bit of a duff model? I charge my phone over night & yet I find I'm having to charge it again by 6/7 in the evening.
