Tablet 2013, most apps are not supported

You mean Note10 plus 12GB/256GB..?
Or Note 10 that have 8GB/256GB

if u dont mind getting sd set would be better.
better antenna, slightly better battery life (as per review)
do note ur last android update will be next year.

if u dont mind not latest software updates, pretty sure u can use it another 3 years no problem.

the camera tbh performs quite well till today on day to day usage.

Note 20 ultra u can consider if u have the budget (120hz screen ) is really worth it for the extra cash.
provided u dont mind lower resolution at 120hz (most ppl wouldnt mind)
awesome camera on the note20.

Note 20 ultra probably would be a collectors item as it might be the last galaxy note ever produced.

i upgraded from Note 4 to Note 10+, considered Note 9, 10+ and 20U, but bought Note 10+ in the end, due to Note 10+ is getting 3 years of software support, spec isn't losing to Note 20U at all, and the price is just right

i got mine last year during 9.9 sales at around RM 3k, funny enough just after 2 months, Note 10+ is available at RM 2099 on 11.11 

hmm.. to me the difference between SD & Exynos on 10 series is minimal (if compared to 20 series), plus we have the benefits of having local warranty and a few more functions such as Samsung Pay & etc
