recently returned a dead AP Z1 to Satu Gadget for warranty. They changed a 'new' one, was happy suddenly realize phone like used before upon checking, etc slight scratches & glass screen at top right got gap with aluminum frame.

Feedback to them then they straight exchanged another Z1, but still think is some other customer return set, as got screen flickering problem. Sigh, AP warranty mmg cannot if phone brick.

you better get ori set if you wish to use underwater feature .. my phone dead when I used it underwater although I closed every cap on it.

sending to claim for warranty.
