回答“G-sensor have broken Moto X 2gen”I had the same problem today with my Moto X 2nd gen. Dropped the phone from chair: height = 20 cm. I read here: http://forums.androidcentral.com/google-nexus-4/264976-screen-won-t-rotate.html slapping on the back of the phone( middle or a bit low in my case) fixed my problem. I just slapped 3 to 4 times moderately. and it works for me. (now I can sleep with peace...) This is funny though: (read the comments as well before trying any thing) https://www.reddit.com/r/Nexus6P/comment...
