Hi everyone, I have a problem with the proximity sensor and the ambient light sensor of my white iphone 6s. I replaced the front panel with a non-OEM part. at first the proximity sensor did not work. with an indelible marker I obscured the sensor housing and worked. if I make a call and then put the phone to my ear, the display goes off. if I receive a call and the phone is on the table, when I put it to the ear the display goes off. if instead I receive a call and take the phone out of my pocket and put it to my ear, the display will not turn off. I did a test: if I receive a call and I cover the proximity sensor before answering, the display will not turn off. if, however, I cover the ambient light sensor before answering, the display on call will turn off. if I receive a call and the phone is in my pocket, I answer, press the home button and then return to the call, the display if I put the phone to my ear, goes off. what could be the defect? thank you all

Did the replacement screen come with the Front Camera Sensor flex pre-installed? If so, those usually contain a lower quality aftermarket flex and can be the root of your issue. In that case, I would recommend you transfer over the original flex from your damaged screen, following this guide. If you did migrate your original flex, then tale a closer look at it to see if the flex was damaged, such as a tear or broken connector pin). Update (05/24/2018) Hi @refectio the screen arrived without flex. the sensors are original apple. in these two days I disassembled and reassembled the flex several times, placing the sensors in the correct position. The sensors are clean

Hi, some news: if I leave the phone with the display facing down and someone calls me, if I put the phone to the ear, the display doesn’t turn off. But if I put the proximity sensor on the surface where the phone was first, the display goes off.
