Many iPhone 4S user complain about the screen, saying that has a yellow tint that’s visible every time they compare their device with iPhone 4 or iPhone 5. This is a common problem encountered at some 4S devices, and it has something to do with the glue that was used to stick together the digitizer and the display. Don’t worry, there is a fix for the yellow screen. You don’t have to send it to warranty just for this. The problem is that you have to Jailbreak your phone in order to use it, because Apple does not allow screen color balance in their iOS. So, if you have a jailbroken device, you can use this fix. Search for Color Profiles and install it. After that, go to “Settings” in iOS, and you’ll find Color Profiles there. Select it, then select the “Bold” profile (set it to 50%) and set the Color Temperature to 50%. You’re done, the yellow tint on iPhone 4s is gone. Don’t forget to tell your friends about it.
