Congrats, Knight. I did exactly the same several months back, was offered a huge trade in by Samsung for my Flip3 and I had been missing my stylus. I also had a small issue with the screen protector coming loose on the crease, so I thought I's try to avoid repeat annoyances and go back to a solid slab.
I really do like the S22U -- great performance, great photos, but I have really not used the SPen as much as I thought I would. Lately, I have been noticing the size of the S22U and am seriously considering going back to the Flip4 when it comes out in August. Will see how goo a deal Samsung offers on the trade.
Congrats again, and good luck with your new
