For anyone saying that true tone will not work after a screen replacement, there is a way. You just need an iPhone screen reprogrammer. There’s one online called the JC PRO1000S which is used to transfer the phones serial number onto the new display so true tone will work again. If you can’t afford the JC PRO100S, just get the JC V1 which can be found here: https://www.jcprogrammer.com/jc-v1-iphon...
This is the JC PRO1000S https://www.jcprogrammer.com/jc-operatio...
You’ll need to download a program after getting the product, but after that you should be good to go.
For anyone going to question how I know this, I watch a lot of Hugh Jefferys videos.
Keep in mind this will only work with the iPhone 7 and later.
