The front camera in my Mi Mix 2S isn't working.

Hello

I have a Xiaomi Mi Mix 2S and everything but the front camera is working. When I switch to the front camera it just swaps between the two rear camera’s.

From what I’ve already read online, it seems the front camera module is toasted. Is this hard to fix? I have never disassembled a phone but it doesn’t look that complicated based on the taerdown videos.

The camera module itself is pretty much the exact same as in the Mi Mix 2. Some guy used a 2’s module on a 2S.

Thank you in advance!
