I have the Note 10+ and S22 Ultra and as devil's advocate, here are some reasons to possibly consider staying with the Note 10+ at least another year.
* Some may consider the power and volume buttons on the left side and the pen silo on the right side to be easier.
* Both phones have 6.8" screens and nearly identical height and width, but the Note 10+ is noticeably thinner and lighter.
* If camera quality isn't super important, then you might appreciate the Note 10+ has a nearly flush camera housing, something note seen on a flagship phone for couple years now.
* Note 10+ has the same 12GB of RAM as the S22 Ultra (entry S22 Ultra model starts at 8GB).
* Snapdragon 855 still is capable.
* Note 10+ just got Android 12, so still running latest version of Android.
* Note 10+ has a micro SD slot.
