I was having random restarts in every 3 days 'regularly' before getting Amber and so I thought it would get fixed in Amber but NO. My phone still restarts in about every 2-3 days regularly as if i've set a timer! It is the most annoying thing for me to have it in a phone. I can even bare lag but restarts just spoil it all for me. The restarts occur only if I don't restart the phone my self by powering off and on. Tried several hard resets before Amber but the problem still persists in Amber as well. Disappointed. Is it the same with you guys?
