Work from the symptom and try the least destructive fix first: restart the phone, check for Android and app updates, review free storage, and use Safe Mode to test whether a downloaded app is involved. Save a factory reset for last; it removes phone data, so back up before considering it.
Start with the symptom and recent changes
Note what is going wrong—general slowness, one app, low storage, or a connection problem—and whether it began after installing an app or changing a setting. Android menus and troubleshooting steps vary by phone and Android version, so the labels below may differ on your device.
If the problem persists after the general steps here, consult your phone maker’s support instructions. Use its guidance for device-specific menus and button sequences rather than assuming one combination works on every Android phone.
If your Android phone is slow
- Restart the phone. Check whether performance improves after it starts again.
- Separate connection trouble from general slowness. If pages, downloads, or online features are slow but other phone functions seem normal, check your connection settings and network before treating it as a device-performance problem.
- Check for Android updates. Open Settings and look for the system or software update option; its exact location varies by manufacturer.
- Update apps. Check the app store on your device for available updates, especially if the trouble is limited to one app.
- Review available storage. Google says a phone can start having issues when less than 10% of its storage is free. That is a warning threshold, not a guarantee that every phone will slow down at that point.
Free storage without deleting the wrong thing
Inspect storage categories before removing anything. Prefer files you recognize and no longer need, or apps you no longer use. Google’s storage instructions vary by Android version; some apply only to Android 14 and later.

Cache is not the same as app storage
Clearing an app’s cache deletes temporary data. The app may be slower the next time it opens while it rebuilds that data. Clearing an app’s storage is more consequential: it permanently deletes all data for that app. Read the confirmation prompt carefully and make sure you understand what will be removed before choosing it.
Use Safe Mode to check for a downloaded app
Safe Mode temporarily turns off downloaded apps. If the problem disappears there, Google says a downloaded app is likely to be involved.

When a factory reset is appropriate
A factory reset is a last resort after simpler troubleshooting and manufacturer support. It removes phone data and uninstalls apps and their associated data. Back up anything you want to keep before resetting. Also consider that restoring an app afterward may bring the original problem back.

Choose the next step by risk
| What you notice | First steps | Data risk |
|---|---|---|
| General slowness | Restart; check Android and app updates; review free storage. | Low; these checks do not require deleting personal files. |
| Slow online features | Check connection settings and the network. | Low. |
| One app seems involved | Update the app; use Safe Mode to test whether a downloaded app is responsible. | Low for testing; removing an app can remove its associated data, so check what you need to keep. |
| Storage is nearly full | Inspect storage categories; remove files or apps you no longer need. | Depends on what you delete. Clearing cache removes temporary data; clearing app storage permanently deletes that app’s data. |
| Problem continues after other steps | Ask the manufacturer for device-specific help; consider a factory reset only after backing up. | High for a reset: phone data and apps are removed. |
