Before ios 8 and 8.1 I had 6 months between a hardreset now im above 10 hardresets a day when ipad was in use. Last days it has started resetting by itself even when not in use. Every time i open it i have to "enter pin after reset" Can it be a hardware faliure or just the ios? I hope 8.1.1 can fix it but with less than two months until warranty runs out i really want to know if this is just a software faliure! For now the ipad4 64gb LTE is more or less useless. Solution is maybe to reset the ipad from factory settings and not use the icloud backup. Ofcourse i would like to awoid the large complications that comes with that. Should i try the factory reset and not use the backup before returning it? To me it would mean hell to again spend a day entering logins for services. I have a combination of many of the errors i see in here from lag to "no sim" icloud problems etc. etc.
