Even if I follow the stept to start the game, after the last long press on the logo, instead of starting the game, the phone gets back to the device info section in settings.
It might have been Marshmallow, I can't really recall. As for owning a P9, I do not.yes, that game is like flappy bird, but i also had it on a sony and a samsung that had aldo android 6. do you have a p9? can you try to start the game? thanks man!
