Our verdict
The first Samsung phone to ship with Android 12L, and the cheapest Fold that still has a full update runway left.
Pros
- 4 OS upgrades and 5 years of security patches, with support running to around August 2027
- Snapdragon 8+ Gen 1 remains plenty fast for multitasking
- Slimmer, lighter and more refined than the Fold3 it replaced
Cons
- Same 4400mAh battery and slow 25W charging as newer Folds
- First-launch Android 12L means it burns one of its upgrade slots on a minor version
