Not ideal at all. It works, but inconsistently at best. The proximity sensor isn't working properly either (screen doesn't dim when you hold the phone up to your ear on a call) and the lightning port is a bit dodgy.
Not impressed. I've complained to the insurance company so will see what they say. At this point I'm considering making-do with this one until the 12 comes out, selling this 8 plus and binning the insurance.
