The attack of iOS9.3 Beta4: new features get a head start.

In the early hours of this morning, Apple's developer version of iOS9.3 Beta4 was officially released. Users can update it through OTA, or they can choose to download it from Apple developer Center.

It is reported that the size of the iOS9.3 Beta4 is about 163MB, and there are no major new features added to the updated content, but the "Night Shift" icon in the control center has been redesigned.

Among them, Night Shift Haitian loves the new function of weakening blue light, which automatically changes the color temperature of the screen according to the time and location of users using iPhone or iPad, so as to reduce the blue light released by the screen.

At the same time, this version also adjusts the interface of health apps so that users can see their own steps more intuitively.

In addition, under the system, iPhone can be paired with multiple Apple Watch.

It is important to note, however, that this update requires you to sign up for an Apple developer account.
