Dear Christofer!
I'm a retired software man. This case is not so complicated for Your software team, if all z2 work fine with Lolypop, and most of them have problems with Marshmallow, then it's Marshmallow. I've sent my Z2 to local support team, but the only thing they may do is mic testing, The mic is OK!! that's an answer I got from them. Still the phone can not be used for call, since the caller or doesn't listen at all or listens waterfall!! I did twice repair, it helps shortly, but the problem returns, that's clear for me, it's program overlapping when using Marshmallow.
Shame on Sony, you're selling a phone which has been converted to piece of plastic. Many respectable companies did recall.
We are going to buy 2 new phones for grandchilds, should I buy Sony??
I really wish all the best, and I'm starting to check possibility of loyal sanctions, if Sony will proceed to tell stories, instead of finding solution.
My respect.
