Have you ever looked at pictures on your phone or tablet and thought the colors just don't look right? If you have to quickly and easily calibrate your screen using a very neglected feature in iOS, you may not know its existence or know it, but I passed it unnoticed, and you know how to calibrate the screen of the iPhone.
Someone said, after replacing the iPhone 5s screen, he noticed that the colors didn't look exactly right. Which started to bother him badly. And after research and suggestions to cancel the operation of the night mode or play in the lighting in terms of raising or lowering it, but the matter did not help. He also went into accessibility and played in grayscale and inverted colors, but that also never corrected the situation. However, he found a method that completely resolved the problem.
◉ Open Settings, then General, then Accessibility.
◉ In the Accessibility section, you will see an option called “Screen and Text Size”, the name might be different in some older versions.
◉ Here you will find various features related to screen and more. What we are interested in is the "color filters", which are set to "off" by default.
◉ Enter this section and activate the color filters, and here everything will be grayed out.
◉ When you turn on Color Filters, you can choose from four preset filters:
◉ grayscale
◉ Red / Green Filter
◉ Green / Red Filter
◉ Blue / Yellow filter
Below each section is an explanation of who suffers from a specific color sensitivity.
If you have sensitivity to colors or light, click on "Tint of Color" at the bottom to change the color tone of the entire screen. Use the sliders to adjust the screen tone and intensity of the effect.
