    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.

    Tests done:
    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

    My configuration
    Device: Lenovo P780
    Android 4.2.1

    Ideas? Hints?
    Other places where I might find answeres?

    Thanks

    Sounds like there could be an issue with the BT stack in that version of Android.

    Have you checked to see if there may be an updated OS version available? If you are on the latest then you might try downgrading to an earlier version.

    Wish I could give you a definitive answer, but I can't.....

    Interesting, when I moved from 3g to 2g, the problem was solved
    (moved the sim to 2nd slot OR disabled the 3g services for the driving time)

    my guess: 3g plus bt plus dialing is "crashing" the antena

    Interesting, but certainly not very desirable if you have to give up 3G.

    Every day is a learning experience....Thanks for sharing!

    the advice I got from my "guru" (17 years old kid) is to take from my provider 3 sim cards: in slot 1, to do all my things and in slot 2, only for outgoing calls :)

    LOL!!! What is the third SIM for?

    Here in the US we don't have multiple SIM phones so this issue would be a bit more problematic. Glad you found a way around the issue.
