I'm getting extremely frustrated, I have done a hard factory reset 4 times and it has fixed some things like knock on And off works again, it's not getting hot YET, but it seems as though battery is still draining too quick, my keyboard lags, AND my service is in and out and on 3G network, when all other iphones in this household have 4GLTE, not liking this. I don't pay as much as I do for slow service or no service this needs to be fixed. Like Yesterday!
