It would appear that Samsung have taken the opportunity with this newer Beta firmware for Android 11 to make some major camera improvements for the Galaxy S20 Ultra that are, for once, tangible.
The Global Exynos Beta release for Android 11 and OneUI 3.0 has had a camera upgrade.
The
G988BXXU5BZTJF release has an update for the camera to version
11.0.00.59 which brings with it some noticeable improvements as detailed by Sammobile detail, here...
New One UI 3.0 beta firmware improves the Galaxy S20 Ultra camera
These improvements are even evident to a camera noob like myself. It launches a lot quicker than before. Particularly as I use the double press on the Power Button method to launch the camera. The photos seem crisper and clearer and there has not been the occasional crashes, so far, that I used to get.
However, Sammobile state that there is an issue, "an excessive wobbly effect occurring sometimes when using the ultra-wide sensor. We’re not sure exactly what triggers this unwanted phenomenon but whenever it occurs, it can render your recording useless."
I have not experienced this yet but I am sure that Samsung will be looking into it before the eventual stable release. Any camera improvements to the Samsung Galaxy S20 Ultra are welcome particularly when you bear in mind that it is still one of the most expensive phones on the market and was sold on the camera's abilities.
[NOTE] This version seems to have started being pushed out to some of the
U.S. Galaxy S20 devices in a second Beta update launched a few hours ago.
