ParvejChaudhary i also had same problem brother, Nothing phone may have used some cheap screen because a lot of people are reporting this issue i have also done the same in the past and they simply says that this is normal every phone has that which is not true at all.
I have already uploaded the photos in my account but I’ll re-upload it for you just check it once.
And don’t forget to upload it everywhere else also so that people can get to know about this issue
Not only that there screen are not even flat because of that tempered have lot’s of bubble.
I am also resharing this so that Nothing team consider this a serious fault with their screen partner or manufacturers.
For you please go to the service centre if they don’t change it simply go to the consumer court and they will then correct it for sure.
I am also disappointed with there response and with the quality of the phone as well.
