Well, Nougat is turning out to be disaster. Since performing a clean install using Xperia Companion, I've had battery drain and app crashes – and now I've got another persistent problem. I keep getting the 'no sim-card, no service' message regularly (every few hours), which requires a restart of my phone and it's getting seriously annoying.
Has anyone else experienced similar? I'm thinking of installing Lollipop on my phone again because this is a shambolic mess. I'm so angry at Sony for once again pushing out a mess. I love my Z5, but I'll never get another Sony phone after the many issues I've had since owning it.
