2104. Of unknown provenance, bought second hand in Bangkok.

Everything works perfect, but the hard coating has flaked off the screen (about a square inch worth) in one corner. Keyboard is matte.
Frequent cell signal dropout for a few seconds at a time, but that could easily just be crappy coverage.
Works perfectly with 64GB Kingston micro sd card (U1, 'normal' black label). Does not detect new micro usb flash drives. Tested with a 'double sided' 16GB Toshiba. Older flash drives work fine with a generic otg cable
