Hello there, can anyone help me?? Dis Apple had a secret code like Samsung (#0#) ??
Nope there is no secret code to test the display. You can use an app to test the screen however.
You can check your screen either the panel is replaced or not by comparing your iphone to another which you think is genuine.
Hello: No secret code. However, the link to the APP for a screen test is in the iTunes store. As of August 23rd, 2017 you have Version 4.0. https://itunes.apple.com/us/app/touchscr… You can test the pixels, touch, pinch, move, multi-touch on 6s and beyond. Remember, aftermarket replacement screens DO NOT provide the moisture seals, response, and drop performance so please use Apple Care or a Certified replacement brand such as eVero. Your iPhone is worth it. Enjoy, have fun.
Apple uses a special factory firmware called SwitchBoard to perform factory calibrations. It is NOT possible to install it without factory or service center tools, so there is no code to stare test mode because it is likely never there on retail devices in the field.
