Android 8.1 breaks multi-touch in some cases
The problem that was addressed on the Developer Preview of the Oreo system somehow reached out to an official version. It's a mistake in which the touch screen will not register your touch at multiple points, such as when you zoom in on a picture or play games. This mistake is a serious omission since it is known from before, but it can be fixed with a new system update. Oreo version is quite new, and this should not disappoint anyone.
There is a video below that shows this error.
Reverting to the Oreo 8.0 version resolves this problem, and it is sure that problem occurs because of a newer version of the system. Google replied that they are familiar with this issue, and they are currently looking for a source of this bug. Orin, community manager on Pixel User Community replied:
