A:AnswerIt worked just fine for Google Pixel XL 2.
It does not work on some but using it for scrolling, music selection, choosing apps on my phone. Push the @ symbol to switch some functions for games other than that I would be bummed out like you if it did not work just get a refund. Men out their works great for the Gameboy advanced emulator called the myboy from the play store.
A:AnswerThe focus is controlled through trying combinations of the wheel on top and the wheels on each side of the unit. Having said that, I can't get it to focus well with my S8, S7 Edge or S6. The best I could get was slight double-vision. Enough to give me a headache. Hope that helps :)
A:AnswerI couldn't get a clear enough picture with my S6 (or newer Samsungs either). I think part of it is based on the fit, distance between your pupils and the position of the sun. Well, maybe not that last one
