Not true at all. Heck, I'm browsing this forum with 2GB of DDR on an eMachines from 2008 and everything shows properly. My Note II was no exception. Browsing the web was possible with an HTC EVO with 512 MB RAM. Browsing the web is literally a core function of any smartphone including the ancient Nokia N-series.
Any smartphone, regardless of how old it is, can still do all these things in 2022:
1. Browse the web
2. Send/receive email
3. Play locally stored music
4. Take pictures
5. Send/receive text messages
6. Send/receive phone calls
7. Store files/download
8. Take notes
9. Calculator
10. Watch videos stored on internal memory/SD Card
Those core functions don't stop working due to age, although some sites might break due to SSL being evolved over time, but you can still see pictures/browse with any phone today. Now, apps depending on more recent OSs might not work, and many didn't exist when certain phones were made, but those core functions don't need a lot of spec to work, and all still work today.
