I have the same issue. I called customer service and they asked me to go to an Apple store. Today i went the the Genius bar in World Trade Center, New York City and they said it was a hardware issue and they can fix it if I pay $275 to replace the screen. I asked them that, in this thread, there are over 120+ "i have this problem too" complaining for the same issue since Aug 21, 2020, i.e. in less than 4 months, how do you know it is not a product defect but my fault causing it, so I have to take the cost of fixing it? The guy at Genius bar just said "it is not my job answering you this question. You need to call customer service again to reflect this to the engineering team. It is not my job to reflect this". He also said, "obviously this issue is not widespread enough for Apple to give you a free replacement. We cannot give you a lenience.". I argued back that "I'm not even asking for a lenience at all, I want to make sure there is a channel Apple can know its potential product defect, rather than having consumer suffer from it and fix it at their own cost. In this thread all the complains are about the same model having the same issue and this not normal to me at all. I bought my iPhone 256GB really expecting to use it for more than 3 years, and now less than 2 years I cannot use it any more. I didn't do anything about it and it just suddenly happened, and I do see it as a product quality issue rather than my fault." I do encourage everyone seeing this problem here to REPORT your issue to customer service to make them aware. As long as they notice that it is a widespread issue, they might have a free replacement or recall, just like what they did for iPhone X or 11.
