We will share a new repairing way for the new fault.
iPhone 6S Plus happens the compass and screen flip fault, maybe its master don't use it carefully. And according to our ever experience, maybe some chips was damaged as of the abnormal using.
Firstly, we need to find the fault part, so have to disassemble it with the pry opening tool, then we start our fix process.
If the iPhone 6s Plus screen flip is abnormal, it will affect the function of compass, so let us start our fix process.
1. Use opening toolkit to disassemble the iPhone 6S Plus, we have to replace a new gyroscope chip with QUICK 861DW hot air station at suitable temperature, you will also need to carefully take off it with a precision tweezers. However, it doesn't seem to be a problem of the gyroscope chip since the same problem still exists after that.
2. Take off the iPhone 6S Plus motherboard, then observe it under Trinocular Stereo Microscope microscope, it is found that there is corrosion trace around the iPhone 6s Plus compass chip. When we remove the compass, we find a spot is oxidized. As shown in picture 15-10-2.
3. Apply some Mechanic BGA solder paste on pad and then weld the original compass chip back, it still doesn't work.
4. Replace a new compass chip on the motherboard, finally the iPhone 6s Plus flip screen and compass function restores normal. (we estimate the compass chip is damaged by liquid, thus the screen flip function is also not normal).
5. Re-stall the iPhone to test , all the function is normal now!
