Samsung has a more advanced camera app called Expert RAW that gives you more control over the cameras on the Galaxy S21 series, S22 series, and the Galaxy Fold3 (with support for the S20 Ultra, Note20 Ultra, and Galaxy Z Fold2 delayed). The app lets you shoot with any of the cameras on the device with full control of the shutter and ISO.
The latest version of the Expert RAW app 2.0.00.3 expands support to the Galaxy Z Fold4. The new app version also improves image performance in low-light with the ability to add custom presets.
There is no mention of support for the Galaxy Z Flip4, though none of the previously released Z Flip models have ever been supported by the Expert RAW app.
To download Expert RAW on a supported Galaxy S or Galaxy Z device, head into Samsung’s Galaxy Store.
