Apple released the official version of iOS 12.2 a few years ago. For many iPhone and iPad users, it still needs to be upgraded. First, many bugs were fixed, and then new adjustments were added.

First of all, those who buy new AirPods must upgrade iOS 12.2, because the iPhone has fully supported new headphones since this version. Secondly, in the new system, Apple has become more open, or more friendly.

Now developers have found that after updating iOS 12.2, some third-party stylus has already supported iPad writing. For example, Logitech crayons, 20 18 can be used on 1 1 inch new iPadMini and iPadPro, and all handwriting input is very smooth.

Previously, Logitech crayons were only compatible with the 9.7-inch iPadPro launched last year, but with the update of iOS 12.2 system, support for other iPads was finally introduced.

Compared with Apple's own stylus, Logitech's is obviously much cheaper. Now that Apple has liberalized its system restrictions, it is quite rare to access third-party product support.
