Well I tried to go another route this year. Have had almost every Note except the first one and Note 5. This year seeking a change I gave my Note 10+ to my wife and bought the LG V60 Dual Screen thinking it could replace my Note experience. The phone is a good phone, and the stylus works good and sometimes I would use both screens at once reading on one screen while making notes on the other. Worked like it was created to do. BUT, for me not having the stylus in the phone made a huge difference. I was constantly finding myself not having the stylus with me or taking the second screen off and not using it. Also I missed some of the things i took for granted with Samsung and that is software. It just works well with my watch, and my t.v.s. I also missed DEX. Plus not every function on my Galaxy Watch 3 works with phones not Samsung. Anyway I took my Note 10+ back from my wife. Bought her the A51 which she loves and will either hang on to my Note 10+, or eventually get the Note 20 ultra.
For me I just can't step away from Samsung, Also don't think I want the S21 with a stylus that doen't fit in the phone, even though they have a case for it to hide in. So my feeling is no, I want leave Samsung again. Too deep into their watch, their smart home automation, their t.v.s. Like some who have apple phones, they are too "walled in" to leave the apple system, I am too "walled in" to leave Samsung.
