G-sensor, accelerometer doesn't work?

Hello

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

Take apart the motherboard and see if it's warped / bent near the wifi antenna connector. There is a small slot on the frame and the board has to go in there. If you overlook this and screw everything back in place, the forces will warp the board. Happened to me, learned it the hard way :(

The acc/gyro chip (330DC) is in that area. If the board is warped, it may break the solder joints of the chip. You can straighten the board again with pliers, but that didn't fix the solder joints in my case, good luck.

Thanks. It really works. Luckily I had solder joints in place. Used 2 credit cards to flatten the mainboard.

Now all sensors work perfectly.

As the display frame was not original I had to remove some blue thermo conductive plate from the frame, where the processor is placed on, to place the mainboard in a right way.

I bought a new mi note 3 . A week later I found that my phone cannot detect its actual horizontal or vertical position. Its shows a 3 degree deflation. Now the problem is when I play a racing game, car move to left even if I keep the phone horizontally on a table. Is it possible to correct this deflection myself
