r1k2rs its still not fixed for me. I compared 2a vs 2a Plus both during calls and tested their proximity sensor. I found out that the sensor on 2a Plus is less sensitive as compared to 2a. I tested it by keeping both phones flat screen up, started a phone call from 2a to 2a Plus, and placed my hand over both phones simultaneously. I noticed that the screen on the 2a turns off when my hand is approximately 10 cm above the screen, whereas the 2a Plus screen turns off when I bring my hand much closer to the screen, approx 5 cm.
I don’t know if I explained it well, maybe I’ll have to record a video for this.
Sometimes I completely press the phone against my ear but still, the screen doesn’t turn off. I am thinking of going to the service center for this.
