The values of meta viewport attribute are not reflected when in full screen mode in android chrome browser.

[agnelvishal]

When I am in full screen mode in android using fullscreen api, the values of meta viewport attribute like initial-scale and user-scalable are not reflected in the browser. If I am not in full screen mode, the values of meta viewport are reflected. I don’t find any source saying meta viewport will be disabled in fullscreen in android. So am I making any mistake or no one has documented it? Also want to know if there are alternatives. Like can I zoom programmatically or can I go fullscreen in css.

I don't think this has been considered one way or another.

Also, I believe https://drafts.csswg.org/css-device-adapt/#viewport-meta is all we have with regards to documentation of this <meta name> value... Not exactly great.

I was able to go fullscreen by an alternative way using web app manifest https://developers.google.com/web/fundamentals/native-hardware/fullscreen/#launching_a_page_fullscreen_from_home_screen
