I am using galaxy a50. During call or taking call the screen is not getting off when earpiece is kept near ear. Usually all other phones which I have used gets off when it is placed near ear. But this is not the case with A50. I checked the proximity sensor with, its working ok. When *#77692# is pressed the proximity sensor option comes up. The sensor is responsing well when hand is place even at 1cm distance. I checked with other apps, the sensor responded as it should. So, the issue is with buggy code which responds oddly when call is taken. Samsung should take it seriously and come up with solution, as the primary function of a phone is making calls. If this can't be made right, then the phone is useless.
Hope your issue got resolved if not then we request you kindly visit the service center for the physical inspection of your device. To check for the nearest Samsung service center kindly click on the link:- https://www.samsung.com/in/support/service-center/
Whenever i remove it from my pocket the login screen states that more that 15 failed attempts have been made and I need to wait 30 seconds or use my PIN. Also my cheek presses buttons while I'm on a call. Using a test app the proximity sensor either reads 0cm or 5cm, solid objects (paper, tabletops, etc) do not seem to affect it, by a finger does as long as it is very close (almost touching). This phone was an (insuron) replacement for the LG G5 that I took swimming with me. I will not buy a Samsung.
