my phone automatically shut down when I make a call

[felqalb]

My Xperia z c6602 automatically shutdown at some times when I make a call, And some times don't automatically shutdown.
I make hard reset from the software, also I flash another roms but the problem is present at all of them.

The problem occurred after one week from the sudden drop from my hand.

Hi "kryss782001" i face the same problem, also my phone auto shutdown when I make a call
I think the problem is battery, because I try to make a call while the phone is in charge the phone doesn't shutdown.

Can experts tell us how to detect whether the problem is battery or network board circuit.

No one else has problems like this?
When I initiate a call or receive a call, the phone restarts.
Not always does between 1-3 days restarts.
I reinstalled the software, return to factory settings with stamina on and off, do the same.

Get a brand new SIM card and report back, make sure to get the correct size not a cut SIM card

Hello, it seems that the sim card was the problem. The phone was sold and the new sim card is ok.
