I've been running DP3 for a couple of days. It's actually pretty good, and the UI is fine. It's not like Samsung. It's stock, just made to look a bit nicer. Let's be honest, the pixels aren't the nicest looking.
It's still free (ish) from bloat. That said, it is starting to go the wrong way:
netflix
facebook
facebook messenger
instagram
oneplus community
oneplus cardplus thingy (where you store bank cards) <- use google pay?
oneplus dialer, contacts, messages, notes, gallery, calculator (just use googles ffs)
shelf and zenmode I don't really care for
alexa integration? not sure about that, maybe should be left for the customer
Still has your typical UI bugs which have been present for a few years now (feedback sent again!). My app will be updated in the coming days, links on the OP forums.
Regarding android 11. Other than a redesigned power menu (which is great for home control) I really couldn't tell any difference between 11 and 10.
I've not notced any difference in battery life using AOD, so why OP didn't roll this out years ago is beyond me. There is a warning about significant drain when you first switch it on.....there isn't?
