Hi Friend,
Have you ever found that iPhone true tone functionality is disabled after a screen replacement?
Most people thought that this issue only happens on aftermarket screens, which means the true tone will disappear if you use an aftermarket screen. So you may hear such saying like that, if your screen has no true tone function, that means your replacement screen is not original.
That's wrong cognition!
Even an original iPhone screen would miss true tone after replacement.
So how to restore the true tone display becomes a problem. To meet the market demands, various true tone repair tools appear.
There are mainly two kinds of true tone repair tools on the current market.
One can only work with the original screens kept, like
the New Generations True Tone Repair Tool.

The other ones work no matter your original screens exist or not, like
JC-V1 Chip Programmer.
