How to Clear App Data on a Huawei P9

Clearing an app’s data on a Huawei P9 resets that app to its freshly installed state, which can help fix crashes or free space. It also removes information saved inside the app, so check that important content is backed up and that you know any sign-in details before continuing.

What You’ll Need

• Your Huawei P9, unlocked, with enough battery to complete the steps.
• The name of the app you want to reset. You may need your account password or other sign-in details afterward.
• A backup, if the app contains local files, messages, drafts, or settings you want to keep. Check the app’s own backup or sync options first.

Step-by-Step

1. Check what the app stores. Open the app and look for its backup, sync, export, or account options. Confirm that anything you want to keep is synced or copied somewhere safe. If you are unsure whether its data is backed up, assume that clearing it may permanently remove local information.
2. Open Settings. From the home screen or app list, tap Settings. Huawei’s EMUI menus can differ slightly by software version or language, so the wording or location of a setting may not match exactly.
3. Open the app list. Look for Apps, Apps & notifications, or Application manager. Tap the option that opens the list of installed apps. If you see a separate App info option, it may be possible to reach the same screen by selecting the target app there.
4. Select the app. Find the app whose data you want to clear and tap its name. If the list is long, use the search control if available. Make sure you select the correct app; similarly named apps can have different data.
5. Open its storage controls. Tap Storage or Storage usage on the app info screen. On some EMUI versions, you may first need to tap Storage within a section such as Permissions or App info.
6. Choose the data-clearing option. Tap Clear data, Clear storage, or a similarly worded control. Read the confirmation carefully. The wording varies, but clearing data or storage is the reset option; it is not the same as clearing only the cache.
7. Confirm the reset. Tap OK, Delete, or Clear if the confirmation describes the action you intend. Do not confirm if the dialog indicates that you will lose information you still need.
8. Reopen the app and check it. Return to the home screen and launch the app. It may show its welcome screen, ask you to sign in, or request permissions again. Sign in only after confirming you have the required account details, then restore or sync your backed-up content if the app supports it.

Common Mistakes

• Choosing Clear cache instead. Cache is temporary data. Clearing it may help with a minor glitch, but it usually does not reset an app or remove its saved settings. Use the data or storage option when you intentionally want a full app reset.
• Assuming clearing data deletes the app. It normally leaves the app installed. To remove the app itself, use its Uninstall option instead; uninstalling and clearing data are different actions.
• Expecting the reset to erase an online account. App data stored on the phone is not the same as information held by an online service. Clearing local data does not close an account or necessarily delete cloud-synced content.
• Clearing data from the wrong app. Check the app name and, if shown, its icon before confirming. Avoid clearing data for system apps unless you understand what they do.
• Forgetting sign-in details or local files. A reset may remove login sessions, downloaded content, drafts, and preferences. Make a backup where possible and check that you can access the account before clearing.

Tips

• If the problem is small, restart the P9 or clear only the app’s cache first. These options are less disruptive than deleting all app data.
• After clearing data, connect to Wi-Fi before opening an app that needs to download a lot of content. This can avoid using mobile data for a large restore.
• Allow an app to finish its initial setup before judging whether the problem is fixed. Some apps need to rebuild local files or sync account content after a reset.
• Keep the P9’s software and the app updated when updates are available through the phone’s usual update settings or app store. An update may resolve a bug without requiring a reset.

Troubleshooting

You cannot find Apps or Application manager: Use the search field in Settings, if available, and search for the app’s name or “Apps.” Menu labels vary between EMUI versions. You can also press and hold the app icon and choose App info if that shortcut appears, then look for its storage settings.

Clear data is missing or unavailable: Check that you opened the individual app’s info page rather than a general storage screen. Some preinstalled or system apps restrict clearing data. Do not try to force a reset by deleting unfamiliar system files; restart the phone and consult the app’s own settings or support guidance instead.

The app still has the same problem: Restart the P9, open the app again, and check for an update. Confirm that the phone has free storage and that the app has any required permissions. If the issue continues, back up important content and consider uninstalling and reinstalling the app, if it can be removed. Some preinstalled apps cannot be uninstalled.

Your content appears to be gone: Check whether you are signed in to the correct account and give the app time to sync. Look for a restore or backup option within the app. If the content existed only on the phone and was erased by clearing data, it may not be recoverable; avoid further resets until you have checked available backups.

The app asks for a password you do not know: Do not keep guessing if that could lock the account. Use the service’s normal password-recovery process from its sign-in screen or another trusted device. Clearing app data does not reset your account password.

Frequently Asked Questions

Does clearing app data delete my photos?
It can delete files kept privately inside that app. Photos saved in the phone’s regular photo storage are generally separate, but check the app’s backup and storage details before clearing anything.

Will I be logged out?
Usually, yes. Clearing data often removes the app’s saved sign-in session, so you may need to sign in again.

What is the difference between Clear data and Clear cache?
Clear cache removes temporary files. Clear data resets the app’s local information, which can include settings, accounts, and downloaded or locally saved content.

Does clearing app data uninstall the app?
No. It usually resets the app while leaving it installed. Choose Uninstall separately if you want to remove it.

Can I undo clearing app data?
There is generally no undo button. You can restore content only if it was backed up or synced, or if the app provides a recovery option.

Will clearing data free up space?
It may free space used by the app’s local files and downloads, but the amount varies. The app may use storage again as you sign in and download content.
