Phone Opinions Review

With the Samsung Galaxy Z Flip4, Samsung is clearly aiming at buyers who want a well-rounded phone without too many compromises. Here is our take on what it brings to the table. Announced in 2022, August 10, it arrives at a time when the competition is as tight as ever.

Design & Display

Up front there is a 6.7 inches, 101.5 cm 2 (~85.4% screen-to-body ratio) screen, pushing a resolution of 1080 x 2640 pixels (~426 ppi density). Colours look punchy and text stays clean, so you will not have much to complain about here. In terms of design, the Samsung Galaxy Z Flip4 keeps things modern and comfortable to hold. You can pick it up in a few finishes, including Bora Purple.

Performance & Software

At the heart of it sits the Qualcomm SM8475 Snapdragon 8+ Gen 1 (4 nm), paired with 8GB of RAM, which means smooth scrolling, quick app switching and no real hiccups in normal use. It runs Android 12, upgradable to Android 16, One UI 8 out of the box, so the software experience feels current.

Camera

Photography is handled by a main 12 MP shooter that should cover most situations, from daylight shots to the occasional low-light frame. Point-and-shoot results are reliable, and that is exactly what most buyers want.

Battery

Battery duties are handled by a Li-Po 3700 mAh unit, which should comfortably see most people through a full day on a single charge.

Our Opinion

So, what do we actually make of the Samsung Galaxy Z Flip4? Samsung has clearly gone for substance over gimmicks here, and we respect that approach. It gets the basics right, offering a dependable main camera, a crisp display, which is exactly what most buyers are really after. If your priority is a phone that just works, day in and day out, then this one deserves a spot on your shortlist. Is it perfect? No phone is, and you will always find a sharper camera or a faster chip somewhere else for a little more money. Even so, the Samsung Galaxy Z Flip4 holds its own and represents a solid, no-nonsense buy.
