HELP: impossible to receive phone call when 3g is on
since few days I got the following issue :
when the 3g connection is on, I cannot receive (or I cannot make) any phone call as the device completely loses the operator signal and some times I have to reboot it to restore the gsm signal. I noticed tha this happens only when the status bar displays "3g" icon, when in " H+" it works properly.
I put the sim card in a different device and it works, so it is not a network problem.
the problem is that I got this issue with a custom rom ( lg stock based) and then I flashed cyano 11, but the 3g issue is still there!
Could it be an hardware problem?
Has anybody any Idea how to solve?
