Hello All.

Model: Lenovo S820_ROW

Android system version: 4.2.1

Firmware communication module: S820.V21, 2013/08/07 15:14

Build number: S820_ROW_S119_130922

 

I also connected the bluetooth headset. In the phone attached 2 sim: MTS(3g and 2g), BWK(only 2g)

 

Problem:

 

When I call from first slot of sim with bluetooth before whistles Lenovo S820 activate flight mode and disconnect with all providers(MTS and BWK) and after reset call Lenovo S820 turn off flight mode.

 

In second phone I recive call, but I can't answer a call from Lenovo S820.

Goto setting - all setting - more - mobile network - network mode - select GSM only
