If you have the Samsung Galaxy S21 5G or S21+ 5G models, you may want to hold off this AUB3 update with the February Android Security patch.
According to a report from SamMobile...
"All the customer complaints come from people who own the Exynos variant, though it should be stressed that the issue most likely stems from software rather than Samsung’s new hardware. And according to some users, the battery might be draining at an accelerated rate due to an issue with cellular connectivity."
This issue does not appear to affect the Galaxy S21 Ultra according to SamMobile and I can confirm this. from my own experience.
To-date, Samsung has only rolled out this firmware update to their stock, nonicarrier, branded firmwares which could indicate that they may either issue a hotfix or wait until the March Android Security patch.
