Pros
- Genuinely compact flagship that's easy to use one-handed
- 120Hz QHD+ display was a standout and still looks great

Frequently asked questions
How long will the Galaxy S20 5G get updates?
Its support has ended; it received three major Android upgrades and security patches through roughly early-to-mid 2025, and is no longer maintained by Samsung.
Is the Galaxy S20 too small for media?
Its 6.2-inch screen is smaller than most modern phones, which makes it comfortable to hold but less ideal for video; consider the S20+ or Ultra for a bigger display.
Should I still buy a Galaxy S20 in 2026?
Only as a cheap backup or basic phone, since it no longer receives security updates; for a daily driver pick something still in its support window.
