The Samsung Galaxy Z Flip 4 (2022) supports Expert RAW in DNG format and has no mechanical shutter — the image counter stored in each DNG file records total electronic captures. Drop an Expert RAW DNG to read it instantly.
Check Image Counter →The Galaxy Z Flip 4 (2022) is powered by the Snapdragon 8+ Gen 1 for Galaxy and features a dual rear camera system: a 12 MP main sensor (f/1.8, OIS, Dual Pixel PDAF) and a 12 MP ultrawide (f/2.2, 123°). The main 6.7-inch FHD+ Dynamic AMOLED 2X display supports 1–120 Hz LTPO adaptive refresh. The 1.9-inch Super AMOLED cover display allows at-a-glance notifications, quick replies, and selfies without opening the phone. The hinge is rated for 200,000 fold/unfold cycles.
Like all Samsung Galaxy smartphones, the Z Flip 4 uses CMOS electronic readout only — there is no mechanical focal-plane shutter. Every image increments the persistent electronic image counter embedded in Expert RAW DNG files.
| Model | Release | Main Camera | Cover Display | RAW Format |
|---|---|---|---|---|
| Galaxy Z Flip 4 | 2022 | 12 MP f/1.8, OIS | 1.9-inch AMOLED | Expert RAW (DNG) |
| Galaxy Z Flip 5 | 2023 | 12 MP f/1.8, OIS | 3.4-inch AMOLED | Expert RAW (DNG) |
| Galaxy Z Flip 6 | 2024 | 50 MP f/1.8, OIS | 3.4-inch AMOLED | Expert RAW (DNG) |
.dng extension.| What to Check | How |
|---|---|
| Hinge smoothness | Open and close the device 15–20 times; listen for creaking; the hinge should hold any angle firmly |
| Main display crease | Inspect the fold crease at the midpoint of the 6.7-inch display under direct light |
| Battery health | Settings → Battery and device care → Battery. Below 80% warrants replacement consideration |
| Cover display | Check 1.9-inch cover screen for scratches; it is not protected by a screen protector in most cases |
| Cameras | Test the 12 MP main and 12 MP ultrawide, plus the 10 MP inner selfie camera |
| Image counter | High counter (>40,000) indicates heavy photographic use — not a hardware failure indicator |
The defining upgrade of the Z Flip 5 is its cover display: 3.4 inches vs 1.9 inches on the Flip 4. The larger Flex Window enables full-featured app use — messaging, navigation, Spotify — directly from the cover without opening the phone. The Z Flip 5 also uses the Snapdragon 8 Gen 2 and weighs slightly less. Camera hardware is unchanged between generations: both use the same 12 MP + 12 MP dual rear system.
The Z Flip 6 then takes the larger step: a 50 MP main sensor (replacing the 12 MP) with OIS improvements. For used buyers wanting strong photographic output at a lower price, the Z Flip 4 provides good value with the same core camera experience as the Flip 5.
No. All Galaxy Z Flip smartphones use CMOS electronic readout only. There is no focal-plane shutter and no rated mechanical lifespan.
Heavy social-media users may accumulate 30,000–50,000 captures per year. The image counter is useful context for usage intensity but carries no mechanical wear significance — assess hinge smoothness and battery health instead.
No. The image counter is stored in persistent hardware memory and cannot be reset by any user action.
The Z Flip 4 is a strong choice at a lower price point if you can accept the smaller 1.9-inch cover display. Camera output is nearly identical to the Flip 5. The Flip 5’s larger cover screen and newer chipset are the key tangible upgrades.
