Question A50 vs S20 Ultra

Jun 6, 2023
I am considering upgrading my faithful A50 to the S20 Ultra. The S20U is priced pretty well right now, for the hardware. My A50 is still going strong, but starting to slow down. I currently use my phone for some gaming including emulation.
Both phones will not be having security updates for long though, and this is my main area of concern. I would appreciate having a faster phone, and especially having a better camera. But I don't necessarily want to ensure I have problems if the S20U is so far into its support life.
This is the first time I have considered upgrading to previous-era flagship models, so it's a bit of unknown territory.
