So basically I bought this device 2 days ago.. by default it was having OneUI 2.1 installed on it out of the box.I was very happy with the overall front cam picture qualities and video too but as soon as I UPGRADED TO 2.5. FRONT cam just spoiled ...
Thanks a lot for replying on this post. I just bought it in sale from Reliance digital store. Let us wait for Android 11 then.. if the issue persists I'll reach service center for sure.
