Lenovo P780 & Bluetooth STRANG problem
I'm havig the strangest problem with my new smartphone: in some areas (central Israel), after dialing a phone call with car bluetooth speaker device, I fall off the network and after few seconds the phone reconnects. It' terribly anoying especially since it hardly happen in the northren part of Israel.
When I make the same call (same destination from same location) with the phone without the car kit, there is no problem.
Sometimes the same problem appears when I try to dial, before it rings in the destination.
Other problem, probably related to it is the sound quality- many times the other side claim he can hardly hear me.
When receiving calls, there are no problems (or, at least, very rare)
I tried several attamps to find the problem but can't find a clue of how to solve it, how to focus the issue and not even what is the source of the problem.
My provider claims that since I reconnect almost immidiatly (and didn't have this issue in an old device) shows that the problem is with the device and not with the network.
As pointed out it happens only in some areas and not everywhere
I tried several car bluetooth kits, the problem remains
Using an old device (Galaxy S)- there is no problem
Tried SIM card of another provider- no problem
Tried to change Modem software- didn't help
Device: Lenovo P780
Other places where I might find answeres?
