i have had a few issues after installing 4.12 and havent been able to locate any help via the search feature...
#1 the gps wont locate unless i have the phone hooked up to the computer via usb
#2 the internet on the phone wont connect unless the phone is connected to the computer.
i dont have anything else loaded on the phone, this is right after the install, several hard resets havent fixed it.
also the volume on the phone is super low, ive loaded the lite and full volume boosters seperately, reset, etc and still low, i literally have to have the phone on speaker phone to hear anybody.
any help with this problem will be greatly appreciated.

p.s.
this phone was a warranty exchange and it was brand new when i flashed it
