Samsung has released the fourth Android 10 beta update for the Galaxy Note 10 and Galaxy Note 10+. The update seems to be rolling out in all markets where the Note 10 One UI 2.0 beta program was launched, so you should be able to download it on your device from the Settings » Software update menu. The update's size is nearly 550 MB, but the list of bug fixes is thankfully not as big as it was with the third beta that was released a week ago.
According to the changelog, the update fixes a bug that prevented the phone from vibrating when the S Pen is removed, issues with apps failing to perform normally despite having all permissions allowed, disappearing app icons, and device reboots when playing music, in addition to a few others. It also fixes an issue that made the save/cancel option disappear when jotting down memos with the Screen off memo feature. The software version for the newest beta is G97**XXU1ZSL4 and it bundles the December 2019 security patch.
There's no word on when Samsung will have the Galaxy Note 10's stable Android 10 update ready. The company is currently claiming a January release of the update in most markets, but it's possible the Note 10's update will start rolling out much earlier like the stable update for the Galaxy S10 series.
