Our verdict
Samsung's first 108MP, 100x-zoom Ultra phone, now a cut-price camera tank that no longer gets updates.
Pros

- Huge 6.9-inch 120Hz display and 5000mAh battery
- Supports faster 45W charging unlike the smaller S20 models
Cons
- Software support, including security patches, has ended
- Very large and heavy, and early autofocus quirks were a known issue

Frequently asked questions
How long will the Galaxy S20 Ultra 5G get updates?
Its support has ended; it received three major Android upgrades and security patches through roughly early-to-mid 2025, and Samsung no longer updates it.
Is the Galaxy S20 Ultra's 100x zoom actually useful?
The 4x periscope and 108MP sensor give genuinely good zoom up to around 10x; the headline 100x 'Space Zoom' is mostly a gimmick with very soft results.
Should I buy a Galaxy S20 Ultra in 2026?
It's appealing as a cheap zoom-focused camera phone, but because it no longer gets security updates it's not the best choice as a primary, long-term device.
