Random call drops
I have problem with my Xperia Z2, almost every time I'm on a call with someone I get random call drops.
The cellular signal is full. I don't know what it can be.
The phone firmware is 17.1.A.2.55 (stock) and it says that the phone has the latest updates. (T-Mobile)
Anyone experienced this problem?
Is this hardware or software problem?
