As we know, in order to fix the iPhone Face ID problem in hardware, now there are two common methods, they are replacing the iPhone dot matrix flex cable or changing the IC on the dot matrix flex cable. Generally, we will choose to change the dot matrix flex cable because it is easier than changing the IC. Either way, we need to pay attention to the following issues during the repair process.
1. Positioning problem
What's the positioning problem? When we replace the Dot Matrix Flex Cable, we need to disassemble the iPhone dot projector from the iPhone, and remove the original dot matrix flex cable, and then install the new dot matrix flex cable. During this process, the dot matrix flex cable position is very important, which must be installed to the location where the original flex cable is located.
When soldering new accessories, please make sure that the soldering position is the same as that of the original accessories fittings. Otherwise，the Face ID will report higher or lower problems, or Face ID can not unlock, or unlock insensitive, and we need to re-move higher or lower.
2. Tools problem
After we know how to fix and what to do, the next problem is what tools we should use. In order to fix the iPhone Face ID issue, more and more phone repair tools have been invented. There are several important tools we have to fix the iPhone Face ID.
