To be honest, i am a user of Samsung F23 with 4 GB RAM. And i have seen my friend's realme phone which also have same 4 GB RAM and is 4 years old . But still the software UI of Realme device is way smoother than mine . Even though that device is older than mine and was in a range of Rs. 15k-16k price approx. My device lags sometimes and although i have tweaked so many settings in my device. I think if you want to get Samsung phone then get their Flagship S series models only, but if your budget is less ,then the price to performance ratio is not better in Samsung devices, unless you want only Samsung phone for their ecosystem. But one thing which is better in Samsung is that there are very low chances of getting bugs after getting new updates and there are no bloatwares only Samsung apps which can be uninstalled, and a clean ui. And a lot of security features such as newly added Auto Blocker.
Honestly dont buy samsung A series buy instead s series and a series is worst better buy realme if youre thinking of performance and if ui then samsung and i would recommend get s23 fe or s23 your choice or m55 or f55 if you want a longer lasting phone with everything in between not the best in all but acceptable
I would suggest get S23 FE ( Performance + camera + display ) OR S21 FE ( decent phone with all specs nicely done ) your choice OR S22 ( performance part )
