I can confirm the most of these problems.

Especially the most annoying for me is that bluetooth keeps disconnecting and connecting over and over again every minute with my Arctic P311 (I have two of them). It was OK with Android 6.0.

Other unpleasant thing - I use two simcards protected by PIN, after entering PIN for the first sim card, I cannot enter PIN for my second sim, because everything disappears, I have to turn off the screen and turn on again, then I'm allowed to enter PIN.
