Calls drop when calling.

[CheMasKbg]

I have three and when I tries to make a phone call it drops when it tries to change from 4g to 3g.If I force the force to use only 3g it works. I want to use 4g but it's almost impossible to make calls.

I did a new reset with Sony companion and other stuff. No luck.

Just to clarify, are you trying to make a call through VoLTE?
