OP3 here. Excellent phone, but a few niggles.
All the physical buttons are very “light”. This makes it very hard to handle the phone or pass it to someone else without accidentally pressing a button (the check-in guy at Eurostar rebooted my phone whilst trying to scan the boarding pass code last week)
It’s great that the screen goes pretty much all the way to the edges of the phone, but silly that the touch screen does the same, making it very hard to use the phone one handed.
At the end of last year they did an OS upgrade that changed how vibrate mode works, removing a feature that I (and evidently many others) find essential. Despite endless forum support topics and even a petition, OP are refusing to make the trivial change required to restore the old functionality.
Their attitude on the last point would make me think twice about buying another.
