I had to do a very rare battery pull tonight (wouldn't go on) and pulled off the back plate. When I tried to put it back on the bottom left would not push in no matter what. Verizon does not carry replacement extended battery backs.... told me to call Samsung. I did their chat they said to call during week. Ironically I put the old standard battery back on and it's nearly fits perfectly. In fact I'll use it until the new back gets here. I had no idea how well the standard back fit with the extended battery.
