Description Byungseon(Sun) Shin 2024-01-18 17:25:25 PST
When we tried applied the Fullscreen API behavior applied on the full screen mode of the Cloud gaming using the iOS Beta 17.2 or 17.3 we were getting a prompt often which said “It looks like you are typing while in full screen”. I believe this Phishing message could be shown at first time, but once user want to stay the page, it shouldn't be shown up again.

As discussed through PR#22953, proposing adding new options to get user's approval to allow the full screen with touch events.

How did you manage to play Geforce Now on a iPhone with Fullscreen API enabled?

Considering (1) it is a feature flag that is default off, meaning enabling it will not affect PWAs and (2) Geforce Now does not allow you to play in the safari app, you get hit with a "add to Home Screen" prompt.

Also on iPadOS with fullscreen API enabled in the Geforce Now PWA, touch events are allowed.
