Our verdict

The first foldable with an under-display camera, S Pen support and IPX8 water resistance, now near the end of its long support life.

Pros

  • Was promised 4 OS upgrades and 5 years of security, and reached Android 15 / One UI 7
  • First foldable with IPX8 water resistance and S Pen support
  • Still flagship-feeling with a 120Hz inner screen and Snapdragon 888

Cons

  • Security support winds down around August 2026, so the runway is short
  • Snapdragon 888 runs hot and the 4400mAh battery is only average
Best for: Buyers wanting a cheap foldable to try the form factorBest for: S Pen users who want pen input on a folding screenAvoid if: You need years of future security updatesAvoid if: You want fast charging or strong battery life
