Nokia India — while playing videos on nokia 7.1 green colored transparent layer is forming on the screen

Address:

Madhapur, Hyderabad Telangana, Hyderabad, Telangana

1) while playing the videos on my nokia 7.1 mobile a green color transparent layer is forming on my screen and it is a repeated complaint from the last 6 months, the people in the sevice center were unable to solve the complaint, 10days ago they told me that they changed mother board but still i am facing the issue. Once it turned as green color if i restart my mobile then the video is playing normally (Without green transparent).

2) 2months ago my mobile charging port was failed in its workings, that time i met service center people then they changed port then its charging is working good but from that day i am facing one more new issue which is "when i am talking to other people the other people who are talking with me were getting their voice revert back" sevice center people told me that it's network complaint, i was changed my network from airtel to idea still the issue is acting like a headache for me.
