The Samsung Galaxy Z Flip4 is a compact flip foldable from 2022 that folds a 6.7-inch screen down to pocket size, now very cheap on the clearance market. It appeals mainly on design and price, with a small cover screen and modest battery life the main compromises.
Galaxy Z Flip4: Display
The 6.7-inch foldable Dynamic AMOLED 2X runs at 120Hz with a 1080 x 2640 resolution and a 1,200-nit peak, with GSMArena measuring 919 nits of maximum brightness in its lab test. The cover screen is a small 1.9-inch panel.
The tiny cover display handles notifications rather than full apps, unlike the larger screens on later flips, and the main screen carries the usual foldable crease and plastic layer.
Galaxy Z Flip4: Camera
The dual camera pairs a 12MP main sensor with OIS and a 12MP ultrawide, with a 10MP selfie camera, though the cover screen also lets you frame selfies on the main sensors. Results are good rather than flagship-class.
Video reaches 4K at 60fps, and there is no telephoto, so zoomed shots rely on cropping.
Galaxy Z Flip4: Battery
The 3,700mAh battery is the phone's clearest weak point, returning only a modest endurance rating in GSMArena's test, with 25W wired charging at 50% in 30 minutes, plus 15W wireless and reverse wireless.
The compact folding design leaves little room for a bigger cell, so most users will need a midday top-up.
Galaxy Z Flip4: Size, Weight and Build
At 165.2 x 71.9 x 6.9mm unfolded and 84.9mm tall when folded, at 187g with a Gorilla Glass Victus+ back, an aluminium frame and IPX8 water resistance, the Z Flip4 is genuinely pocketable, in a wide range of colours including Bora Purple.
The IPX8 rating covers water but not dust, and some owners report hinge and flex-cable wear over time, so a used unit is worth checking carefully.
Galaxy Z Flip4: Performance
The Snapdragon 8+ Gen 1 with 8GB of RAM and UFS 3.1 storage delivers flagship-level speed, on Android 12 at launch and since updated to newer One UI versions.
The chip is several generations old now but remains capable in daily use, so performance is not the main concern here.
Galaxy Z Flip4: Who Should Buy
Buy the Galaxy Z Flip4 at a low price if you want a pocketable folding phone and can accept a small cover screen and modest battery life. Buyers who want a larger, more useful cover screen and better endurance should compare the Galaxy Z Flip5. Buyers comparing contract terms will find current network pricing in the table above.
