Every major Android update changes how apps access storage, permissions, and background processes. If you just updated to Android 14, 15, 16 or the current Android 17 and Calculator Hide App isn’t behaving the way it used to, you’re not alone — and the fix is usually straightforward.
This guide covers every Android release from 13 onward, because the permission change that causes the most alarming symptom, a vault that looks completely empty, was introduced in Android 14 and is still the usual culprit today.
Short Answer: Yes, Including on Android 17
Calculator Hide App is actively maintained and updated for compatibility with the latest Android versions. If you’re having issues after an Android update, the solution in most cases is updating Calculator Hide App to its latest version from Google Play.
What Changed in Android 13
Android 13 split the old, broad READ_EXTERNAL_STORAGE permission into three narrower ones: READ_MEDIA_IMAGES, READ_MEDIA_VIDEO and READ_MEDIA_AUDIO. An app that wants your photos now has to ask for photos specifically, rather than being handed your whole storage volume. Calculator Hide App was updated to request these correctly.
What Changed in Android 14 That Affects Vault Apps
Android 14 is the release behind the single most common panic we hear about, so it is worth understanding properly.
Android 14 introduced Selected Photos Access. Instead of the old all-or-nothing choice, the permission dialog now offers a third option: “Select photos and videos.” Choose it and the app receives access to only the specific images you picked, through a permission called READ_MEDIA_VISUAL_USER_SELECTED. Android 14 can also apply this behavior retroactively to apps that were built for Android 13.
Here is why that matters. If you tapped “Select photos and videos” instead of “Allow all” when the dialog appeared after your update, Calculator Hide App can see only the handful of photos you selected in that moment. Your vault will look empty or nearly empty. Nothing has been deleted. The files are exactly where they were. The app has simply been denied permission to see them.
This is not data loss, and reinstalling the app is the worst thing you can do at this point. Grant full media access instead, using the steps below.
What Changed in Android 15
Android 15 introduced further restrictions on apps accessing files in the background and added new health and safety permission categories. It also added Private Space, a separate lockable profile area, which some users now run alongside a vault app. For Calculator Hide App, the main practical impact is that storage permissions may need to be re-granted after the update.
What Changed in Android 16
Android 16 was a quieter release for vault apps. The change worth knowing about is the new Local Network permission, which was optional for developers at this stage. It governs whether an app may reach other devices on your Wi-Fi network, and it does not affect local photo storage.
What Changed in Android 17
Android 17 arrived on 17 June 2026 and is the current release. Three changes are relevant here.
Local network permission is now mandatory. What was opt-in in Android 16 is now enforced. This has no effect on a vault that stores files locally on your device, which is how Calculator Hide App works.
Theft Protection is on by default. Android 17 enables Theft Protection without waiting for you to find the setting. It locks the screen automatically when the phone detects it has been snatched. This complements a vault app rather than replacing it, since it protects the device rather than encrypting individual files.
SMS one-time passcodes are walled off from apps. Apps can no longer read SMS one-time passwords even with SMS permission granted. This is a strong security improvement generally, and it does not affect vault functionality.
Nothing in Android 16 or 17 changed the media permission model, so if your vault looks empty on Android 17, the Android 14 Selected Photos Access explanation above is still almost certainly the cause.
How to Fix Issues After an Android Update
- Open Google Play and update Calculator Hide App to the latest version.
- After updating, open Calculator Hide App.
- If the app requests new permissions, grant them all — particularly “All Files Access” or the media permissions for photos and videos.
- Enter your PIN. Your vault should appear normally.
If your vault still appears empty after granting permissions and updating, see what to do when Calculator Hide App photos have disappeared — it covers the specific steps for permission-related vault issues.
How to Grant Storage Permissions Manually
- Go to your Android Settings.
- Tap Apps > Calculator Hide App.
- Tap Permissions.
- Tap Photos and videos (called Storage on Android 12 and earlier).
- Select Allow all. On Android 14 and later, make sure you are not leaving it on “Always ask” or “Allow limited access” — limited access is what makes the vault appear empty.
- Return to Calculator Hide App and enter your PIN.
If you see “Allow limited access” already selected, that confirms the Selected Photos Access issue described above. Switching it to Allow all restores the vault immediately.
Specific Known Issues and Fixes
Vault appears empty after Android update
This is a permission issue in almost all cases, not data loss. On Android 14 and later the usual cause is Selected Photos Access, where the app was granted access to only a few hand-picked images. Set the Photos and videos permission to Allow all as described above and restart the app. Do not uninstall and reinstall, because that can remove the app’s own storage directory and turn a recoverable permission problem into genuine data loss.
App Hider not showing all installed apps
Android tightened restrictions on apps querying the full list of installed packages. Update Calculator Hide App — the latest version requests the QUERY_ALL_PACKAGES permission which resolves this.
Biometric unlock stopped working
Some Android updates reset biometric app permissions. Go to Settings > Apps > Calculator Hide App > Permissions and re-enable biometric access. Then re-enable it inside the app’s security settings.
Frequently Asked Questions
Do I need to reinstall Calculator Hide App after an Android update?
No. Updating the app from Google Play is sufficient in most cases. Only reinstall if support specifically advises it — and always back up your vault first if you do.
Will an Android update delete my hidden photos?
Android updates do not delete app data. However, if a permission is revoked during the update, the app temporarily cannot read its own encrypted folder — making it appear empty. Re-granting the permission restores access.
