Hi @Rio-kun,

Welcome to the community,

Sorry to hear about this

Just to clarify are you saying that every call that comes through simply drops before you can answer it or does this happen when speaking to any person, can you also advise what happens when you make the call does it drop as well?

Please let me know.

I have the same problem.
But it only started happening after the Marshmallow update.

Also, if I try to make a call, it breaks my LTE/3G reception.

I know that my sim card is working fine. I am currently using it in another device without problems, but this issue persists on my M4 Aqua (E2303), with Marshmallow Build Number 26.3.A.1.33
