Not working proximity sensor

Hi guys,

to my problem:

I have read looots of threads or fixes, or solutions regarding the not working proximity sensor and i know that there are so much topics/threads about it but im still searching for the right solution.

So - right now im using a sensor cable which i replaced myself, everything except the proximity sensor does work. (I still use the original screen)

I have tried 6 different cables including the original stock one on my phone.

And i also tried to fit the sensor the best as possible everytime and ofc with the small plastic bracket where its placed on the stock screen.

On 3 cables including the one im using right now, everything except the proximity sensor works.

Then i have 2 cables where nothing really works and the earpiece is some kind of overheating

And then there is one cable where the proximity sensor is working fine when i cover the sensor with my hand or my ear but the rest like speaker, camera etc doesnt work.

Since i used so many cables i dont think its a cable issue or a connecting port issue or am i wrong?

I would appreciate any help or knowledge i can get here.

Thanks in advance!
