got it yesterday through ota, till now it runs fine. No performance difference so far (no unlock timeout luckily, although the problem was with Oreo June update, you'll never know if it travels to P).
Think I found 2 differences so far. The first is pretty cool, on the AOD you see now the weather under the time, next to the date, the weather icon is in color, looks really nice!
The battery indicator on the AOD looks the same, bit too small in my opinion, little doubt if the font size is +1... but i don't think so.
The second thing that i found is that when you search in the settings, the result isn't flashing anymore but just a solid color that indicates the option you where searchinig for.
Adaptive Battery is enabled automatic after update, i turned it off before, because it just used more battery in standby when i turned it on. In the first couple of hours, it looks like it now works when enabled. After a couple of days it should be clear if it makes the standby drain a little less.
Couple of dutch apps work now, those crashed before when launching them. NOS, Ziggo GO are working fine now. The ABN Wallet app (sort of google pay replacement) doesn't crash on launch, but i need a reader to enable this wallet, and that reader is at home, i'm at work now
I did not factory reset the phone because it is a small update.
