Hello I have a question, hopefully someone can help me. I have a Huawei p30 Leica, bought second-hand, the cell phone was previously reviewed by a specialist, it worked perfectly. The day I finally had it in my hand, I did a total formatting and this could perhaps cause the problem: The intelligent diagnosis of my Huawei specifies that the proximity sensor does not work correctly and the same way the ambient light sensor does not work correctly. It is correct since when calling, the screen does not turn off but if the speaker works, it also happens that when listening to audios in WhatsApp it does not enable the upper speaker of the screen so I cannot listen in private mode due to the sensor. I have tried with apps to calibrate, test apps, look for options in the Huawei that is to activate it in case it is disabled but there is no visible option in settings to solve the problem. With the application "Proximity Checker" when starting the test it puts me on the screen "Proximity Sensor is not available" so it is not available. I wonder if it could be emui 10.1 update error, installation error, formatting error or if the sensor is damaged in the terminal? The Huawei unlocks the screen perfectly with facial recognition, it recognizes when it is in front of my face but it does not recognize in calls, it is rare. Any advice?
