Latest Samsung Galaxy S21, S21 Plus, and S21 Ultra update
June 17, 2021: Samsung is usually very swift with its updates but its June security patch still hasn’t reached a lot of global Galaxy S21 users. According to SamMobile, Samsung is now rolling out a fresh June update to the Galaxy S21 series.
The latest version comes with firmware number G99xxXXU3AUF6 for the Galaxy S21, S21 Plus, and S21 Ultra. It is being distributed in South Korea, Germany, and Thailand as of now, but can be expected to hit global devices too.
The update fixes camera lag issues on the Galaxy S21 series and also includes improvements to the video call effects feature and the Portrait mode.
Besides this, the update reportedly corrects overheating problems on the phones as per the changelog of the Korean release.
If you haven’t received the update in your region yet, you might have to wait a bit longer to get it.
