Mictosoft Lumia 640xl call restart issue

[mackhale]

I own a microsoft lumia 640 xl dual sim. This incident happened two days ago.

While in the middle of a phone call, my conversation was cut. Apparently my phone restarted without my consent. Once done restarting, I tried to call back the person I was talking to prior to the restart. Instead of showing the usual dialing screen, the screen did not changed but instead showed me the dialing pad with the number I have dialed. When I moved it to my ear I heard some ringing. Then it was gone. When I looked the phone restarted again.

Now, every time I try making an outgoing or answering an incoming call, my phone restarts on its own. Help! Why is this happening!?

Does your phone only restart during phone calls? This is quite odd.
