I already have the problem with the proximity sensor, my screen is dark when i’m calling, but now the persons i’m calling can’t here me when the screen is dark (and the screen is always dark), so i can’t call anyone.
I have already tried to reboot my phone OS, nothing has changed.
When i use a sensor application, my proximity sensor display “5 cm”, i block it, so it display “0 cm”, then it never turn back to 5cm it stay on “0 cm”.
Yes, that’s an issue that unfortunately many users experienced before. That’s why Fairphone developed this tool to re-calibrate the proximity sensor and included it in one of the recent updates. So, go for the update and then do the re-calibration.
