iOS 9.3 beta version is launched with new features such as color temperature adjustment and private notes

The first public beta of iOS 9.3 has arrived. It is worth noting that this time it includes a lot of new features. In addition to the newly added screen display adjustment function, private notes have been added, allowing users to hide certain notes, but this feature requires Touch ID to open; Apple News has been improved, with a new horizontal screen mode and video playback in articles; the CarPlay system has been improved; the health application will have a new main control panel. In addition, there are a lot of educational functions integrated into the iOS platform.

The latest beta of iOS 9.3 has added the "Night Shift" feature that intelligently adjusts the color temperature. Studies have shown that the bright light emitted by electronic devices can affect people's sleep. The main reason is that the blue light emitted by LED screens can slow down or prevent the production of melatonin, which can send sleep signals to the brain.

It is understood that "Night Shift" can determine the time of darkness based on the device's clock and location information. After that, it can automatically adjust the screen color to a "warmer color range to make the user's eyes more comfortable." In the morning, the screen color will return to normal. In fact, the essence of this function is to protect the user's eyes by increasing or decreasing blue light. If staring at the screen for a long time at night may cause sleep problems, reducing blue light will help reading and night use. Before this, iOS devices could not adjust the color temperature.
