G-sensor, accelerometer doesn't work?
I have a problem with gyroscope and accelerometer. It all started when I dropped my phone on the floor, broke the screen and changed it by myself. This problem was fixed, but I had to look inside my phone few times more to change some parts killed during screen change. It was fully functioning for some time(maybe month), but then screen stopped rotating, compass stopped..other words gyroscope and accelerometer died. After some experiments I noticed, that it starts working when my phone is uncovered till the motherboard. But as soon as I cover the motherboard and push on the cover(as screws do) gyroscope stops. Gyroscope chip soldered to the board good(tried to heat it) and the contact on the other side is also good. I can't understand what's happened because gyroscope stops when I push on the connector, so it could be bad contact, but also other problem caused by board deflection, and also gyroscope stops working when I push on the board near the chip(from the other side), once again board deflection or bad contact caused by board deflection. Last time I opened my Mi3 sensor stopped working in any conditions. Please find attached photos of 330DC gyroscope chip and the connector on the other side
If anybody met such problems or has any idea what to do - I kindly ask for help
