Clear an app’s cache safely
An app keeps loading the same broken screen, and you want to try a small fix before resetting it. Clear that app’s cache, then reopen it and repeat the action that failed. Choose Clear cache—not Clear storage or Clear data. Cache contains temporary files; deleting app data is a different, more disruptive action.

Know which button you are choosing
| Option | What it does | Decision |
|---|---|---|
| Clear cache | Removes temporary app data. The next opening may be slower while needed files load again. | A limited troubleshooting step for one app. |
| Clear storage / Clear data | Deletes the app’s local data; this can reset its setup and remove information stored only inside it. | Stop and check backup, sign-in and app-specific instructions first. |
Android documents this distinction in its storage guidance. Clearing cache is not a promise that a crash, slow connection or storage shortage will be fixed.
Clear the cache for one app
Finish or save anything you are doing in the app. Choose the app with the problem rather than clearing every app indiscriminately.
- Open your phone’s Settings.
- Open Apps and select the affected app. On some phones, first choose See all apps.
- Open its storage screen. The label may be Storage or Storage & cache.
- Read the button label carefully and tap Clear cache. Leave Clear data or Clear storage alone.
- Return to the app and let it finish loading.
- Repeat the exact task that was failing—for example, opening the same page inside the app.
On a Samsung Galaxy, Samsung’s documented route is Settings → Apps → choose the app → Storage → Clear cache. Other manufacturers and Android versions can use different labels. If the expected control is absent, use your manufacturer’s instructions; do not substitute a reset button. This guide concerns an individual app’s cache, not the recovery-menu “wipe cache partition” procedure. Samsung’s app-cache instructions
What should happen next?
Judge the result by the original problem, not by a temporarily smaller storage number. If the previously stuck screen opens normally, stop troubleshooting and use the app. If it still fails, cache removal has not resolved that symptom.
For example, suppose a shopping app will open but one product page repeatedly fails. Reopening that same page gives you a useful before-and-after check. Opening an unrelated app would tell you nothing about whether this change helped. This is an illustrative scenario, not a reported test result.
It is normal for an app to create temporary files again as you use it. Repeatedly clearing a working app’s cache is not a durable storage-management plan, and a large cache number alone does not identify the cause of a fault.
If the problem continues
Restart the phone and check for an official app update. If only that app is affected, consult its developer’s support instructions before deleting its data or reinstalling it. Google’s app troubleshooting guidance provides an escalation path; app data can be lost during more disruptive steps.
