hangout problem

[YossiN]

I'm using Lenovo P780 (new) with android 4.2.1

from time to time there are hangouts and I see the sign of "flight mod" for several minutes
and than the connection re-establishes
I have noticed it today while driving (don't recall such a situation while in a stable place)
it happened today more than 10 times and looks like I'm having a REAL problem

following an advice in another place, I tried to change settings of mobile provider from "automatic" to manual (my provider)- no good

why is it so?

do I have a bad ROM to be replaced?
is there an application that will help me to keep the connection
is there a tracing app to keep a log and point me when and where the problem happens?
other ideas?

thanks

Are you sure your peovider has solid service in the places where you lose the signal? Run Signal Check Lite in those places and see how good the signal is.

yes, the signal is good, I KNOW it...

someone told me that the baseband v17 is old and could be the cause
1- is it so?
2- if yes, how do I fix it?

thanks
