Excellent! Phone works like new! All functions seem to be working fine (Reception, Wifi, blutooth, speaker, mic, charging etc...). This is a Chinese version board so no LTE band 20 but seller warned me when I asked and I accepted anyway. I installed global version ROM on the board sucessfully. In Europe 3G works fine and I'm guessing 4G will also work within cities as band 20 is more for rural areas. Also quick delivery! Very happy!
Unfortunately something on this motherboard is depleting the battery even when the phone is turned off. It discharged the battery 40% in 7 hours while being turned off.
