How did you install the split APK? It works fine and can record 720p and 4K at 24, 25 and 30fps on my realme 11 pro. Your S22 Ultra should be much more powerful in comparison.
The general populace at large? The amount of ads getting plastered and blasted makes me cringe when I see the non-premium YouTube app. I use adblock and also have premium courtesy of YT music subscription so I'm immune for the most part.
But, non-techy people do not know addblock is an option and also prefer not paying for subscription.
The list of supported phones is limited to pixel and samsung smartphones but you should be able to sideload from apkmirror and get it to run with some limitations depending on your phone hardware.
Supported on phones running Android 13 or later.
Samsung Galaxy S23, S23FE, S23+, S23 Ultra
Samsung Galaxy S24, S24+, S24 Ultra
Google Pixel 7, 7a, 7 Pro, 8, 8 Pro
My experience differs. I found optical in display fingerprint to be quite reliable. It even happens to work with slightly wet hands. The room being too dark or bright has also never been an issue since my finger covers the sensor completely.
I guess it depends on the quality of sensor used by the manufacter. Pixel phones are known to have issues.
Should it arrive to that they can still seize your devices and also force you to unlock your devices biometrics or patterns/passwords regardless. I wouldn't trust law enforcements in this regard.
