I found attaching my OnePlus6 phone to the MA remote a right PITA: the forward facing camera was obscured so the phone didn't recognise me, and registered it was dark so the auto screen brightness went very dim. Couldn't access the settings from the top of the phone's screen or the 'swipe up' function from the bottom, AND I had to take the cover off to get it to fit. All solvable problems admittedly, but a piece of 8mm ply, a couple of screws and some help from RAM mounts, and all these issues disappear! Might need some work to make it commercially viable, but it worked fine today! : )
