Answer to: Front camera blurry after cracking screen?I had this issue several times with my customers. Most of the time by cleaning with alcoholic liquid cleaner or nail polish remover, it will work 100% clear. Make sure you clean the camera lens and exact place where camera stays. Be very gentle while cleaning, because it may crack the part. I am sharing 2 picture with red circles which has to be clean with the liquid i mentioned. Hope it will help. ☺
