Hi My name is Dylan and I have had this problem several times with my iPhone 6s 7 plus recently I have not had this problem on my iPhone X Currently I believe this is after market screens that each company claims are apple certified and are from apple and yet they continue to tell me apple is breaking some of the screens so people that reaplace them at after market stores will have to go to apple although I believe the screens are just plain crap now I also believe you should buy apple care and pay the 29 dollars to replace the screen but that’s my opinion and I encourage you to make your own decisions thank you
