What should we do if the iPhone 7P compass does not work?

Have you ever encountered a situation where the compass cannot be used? This is very inconvenient for us, and our customers have encountered this situation. He sent us an iPhone 7 Plus. The problem is that the iPhone 7 Plus compass is not working properly. This is not normal. We need to repair it.

After we received the iPhone 7 Plus, get into IOS to test the iPhone compass function, it doesn't work.

Disassemble the iPhone 7 Plus by phone opening tools, take out the iPhone motherboard. The appearance of iPhone motherboard looks good, but there are traces of moldy around the gyroscope.

Carefully clean up the moldy areas, and then connect it to DC power supply, it boots normally. Install the iPhone, and test it, everything is fine, except the compass.

For this case, some people will think it's the compass problem, and it can be fixed by replacing the new compass; some people will think that the gyroscope is virtual welded, because the gyroscope is moldy, it can be fixed by reballing the gyroscope.

We need to observe the iPhone motherboard. Put it under the Stereo Zoom Microscope to observe the compass and gyroscope, the parts around the compass are good, but one of the 0 Ohm resistors around the gyroscope is slightly corroded, and two inductors ware also slightly corroded near the display socket.



Touch it with tweezers, it fell off easily. We need to short connect them. Use QUICK 861DW hot air rework station to solder the jump wire, and then clear it up.

Install the iPhone and test it, the compass functions works properly, the problem has been solved!
