Our take on the Samsung Galaxy Z Fold4 Unlocked

The Galaxy Z Fold4 is Samsung's fourth-generation book-style foldable: a 6.2-inch cover screen phone that opens into a 7.6-inch tablet. It runs the Snapdragon 8+ Gen 1 with 12GB RAM, a 50MP main camera with 3x telephoto, IPX8 water resistance and 25W wired plus wireless charging. It suits people who want one device for phone and tablet work, especially split-screen multitasking. Against the Z Fold3 it brings a wider cover screen, a lighter body, a better main camera and a less visible under-display camera; against the later Fold5 it lacks that model's gapless hinge and dust resistance, and the crease and inner-screen durability remain the usual concerns. Owners praise the screen and multitasking but often mention battery life and the outer screen's narrowness.

Questions and answers

Is the Galaxy Z Fold4 worth it over the Fold3?
Yes for most buyers. It adds a wider cover screen, a lighter body, a 50MP main camera and a less visible under-display camera. The Fold3 is cheaper but shows its age in the camera and outer screen.
How does the Fold4 compare with the Fold5?
The Fold5 closes flat with no gap, is lighter and adds dust resistance. The Fold4 has the same screen sizes and similar cameras, so it remains a strong alternative if dust protection and the hinge gap don't matter to you.
How is the battery life?
The 4400mAh battery typically gets most users through a day of mixed use. Heavy inner-screen video, gaming or hotspot use will need a top-up; 25W wired charging refills it reasonably quickly.
Does it support the S Pen?
Yes, the inner screen works with the S Pen Fold Edition and S Pen Pro. There is no silo, so the pen is carried separately, and the cover screen does not support S Pen input.
Is it water resistant?
It carries an IPX8 rating, so it survives accidental splashes and brief immersion. It has no dust rating, so keep it away from sand and grit.
What comes in the box?
Expect the phone, a USB-C cable and a SIM eject tool. Samsung does not include a charger or case, so plan to buy those separately.

  • Cover screenMixedThe wider cover display is an improvement, but some find it narrow for typing.
  • MultitaskingPraisedSplit-screen and app-pair features are widely praised for productivity.
  • CameraPraisedThe 50MP main sensor and 3x telephoto are seen as a clear step up from the Fold3.
