Hi everyone, recently i bought from a friend a n4 with replaced front screen after cracked digitizer. The proximity sensor was not working causing the screen to stay black during making/receiving a call. I googled it and found out it is a pretty common issue after screen replacement and the only workaround was to put some very thin clear tape or a small piece from a screen protector, between the front glass and the proximity sensor. I tried that for a fair amount of time but with no luck. So i tried to put the small rubber piece that covers the light and proximity sensor the opposite way. Now the bigger hole of this rubber piece is on the small sensor (proximity) and the small hole is on the big sensor (light). It worked right away and still works great after a month, The light sensor seems to work fine as well. Confirmed working from another guy as well. So i hope this helps whoever facing same problem after screen replacement. :good:
