I have Samsung Galaxy S9 Plus 256 GB version. I got it because I hate display notches or camera holes. I recommend to get a newer one, or the last Galaxy Note. It's an excellent phone-computer overall. My USB-C dock has HDMI and USB-A which both work as well as with a PC and I use them to connect my classic PC keyboard, mouse and full HD display. On the software side, don't waste your time getting stuff working on bare rooted Android. Download NixOnDroid or Termux and use that like you'd use a NixOS/Debian distro. If you're a Node.js coder, it's very easy to get all your stuff working inside NixOnDroid. Don't worry about installing and using X or VNC, that sucks. You can run VSCode server and access it using Android Chrome or Firefox - that works flawlessly and provides seamless access inside the NixOnDroid environment too. The default OS is well made, no need to reinstall it unless for ideological/privacy reasons - the S9 is actually still getting updates (4 years now). I want to de-google my life so I flashed it and did not install any Google software and don't use any Google services. Flashing ROM on this phone is very easy. I am using ArrowOS. Beware: I am in EU, so I got the Exynos version. Based on XDA-Developers, it seems like the Snapdragon version (commonly sold in US and elsewhere) isn't as hackable - but as I said the default OS is good and you can run NixOnDroid on it too.
