Today we are going to introduce a new repair tool for all repair technicians - True Tone EEPROM Programmer.

Market DemandsThe True Tone option appears under Settings > Display and Brightness. When enabled, it automatically adjusts the screen’s color and intensity to match the ambient light and reduce strain on the eyes.

The latest iOS 12 update did a terrific job in boosting the performance of iPhones and iPads. For the aftermarket mobile phone repairer, the iOS 12 was not so perfect. Because some users complain that the True Tone option disappeared after upgrading to iOS 12. The affected models including iPhone 8, 8 Plus, X, XS and XS Max. Many users suggest that the problem has something to do with whether the device has an OEM display, an aftermarket display, or the original display that has never been replaced.

According to this situation, REWA did a series of tests for certifying. And that’s why we are going to introduce this True Tone EEPROM Programmer today. To begin with, we replaced the iPhone XS original screen with an OEM one. And the True Tone option disappeared after screen replacement, while it was back there with the original screen installed.

Then we programmed the OEM screen with this EEPROM tool. And installed the screen again to test. The true tone option re-appeared on the screen. This is really good news for all the repairing technicians.
