@@msyaban8367 I don't really know how to solve it, but my problem wasn't about the screen not working, the screen was working it's simply that you see just the light of the screen and that's it
i soved the problem. First plug in charche your band , second set up mi fit application on your phone , third application start reset factory your band. (don't forget keep up near your band to phone).
Bought mi band 2 and had a screen issue again bought mi band 3 and used for few months, screen is not responding at all. I DO NOT RECOMMEND MI FOR ANYONE
