I've encountered a strange problem:
The Charge does NOT overheat when using Google Maps on battery power.
The Charge does NOT overheat when being charged(either via AC adapter at home or DC adapter in car),
if Google Maps isn't open.
When Google Maps is open(GPS on) and the Charge is being charged, then the phone overheats and
shuts itself off after a warning message appears.
Verizon replaced the battery 3 times with brand new Samsung batteries. The phone was hard reset each time.
I ended up trying it on the Verizon corporate store's Charge on display. Turns out that the problem can be
reproduced in store.... Does anyone else have this problem?
