The OnePlus Gallery app is preinstalled on OnePlus devices and is updated through the Google Play Store. By using some Magisk mods, it is also possible to install the OnePlus Gallery from the Play Store on a non-OnePlus phone. Make sure you have the latest version of the OnePlus Gallery application.
Hide photos in the OnePlus Gallery
Launch the Gallery application and you can see photos from your camera on the main screen. To view photos other than those taken with your camera, you can press the Collection tab at the bottom. Find the photos you want to hide in the Android Gallery and long press one to activate the selection mode. Tap all the photos you want to hide in the Android Gallery to select them. Then press the three-point menu button and select Hide. You will then see a pop-up window explaining what is a hidden collection. Press OK in the pop-up window to confirm your choice and your selected photos will then disappear from the main screen and your collections.
To see your hidden photos, launch the OnePlus Gallery app and tap the three-dot menu button at the top right. To select Hidden Collection in the menu. You will be able to see all the photos you have hidden. You will also notice that you have not requested a password, PIN code or fingerprint. Indeed, no such option is provided in the OnePlus gallery application. Your hidden photos are not so well hidden. However, it's even better than posting them right in front where anyone can just scroll them. It is quite possible that OnePlus adds security measures in a future update.
Until that happens, consider this Hidden collection as an archive where you store all the pictures you do not need that others see accidentally. It often happens that you give your phone to someone to show him a picture or photos and that they end up scrolling a little too far. The Hidden Collection feature of the OnePlus Gallery app can certainly help to avoid those difficult times. If you want more security, you may need to look at third-party options such as PhotoGuard, Memoria, etc.
