What clearing cache does and why you might need to
Cache is temporary data that apps and your browser store to load faster next time. Over time, cached files pile up and can slow your phone down, cause apps to crash, or use storage space you need. Clearing cache does not delete your photos, messages, or passwords — it only removes these temporary files.
You will want to clear cache if an app keeps freezing, your phone feels sluggish, or you are running low on storage. It is also useful before selling or giving away a Samsung device, since cached data can sometimes contain fragments of personal information.
Key Takeaways
- Clearing cache removes temporary app data and frees up storage without deleting your photos, messages, or account information.
- You can clear cache for one app at a time through Settings, or clear all cached data at once through Storage settings.
- The exact menu names vary slightly between Samsung models and Android versions, but the process follows the same basic path.
- If an app still misbehaves after clearing its cache, clearing the app's data (a separate step) may be necessary.
Clear cache for a single app
This method works when one specific app is slow or crashing. Open Settings on your Samsung device. Tap Apps (on some models this is called Application Manager). Find the app you want to clear cache for and tap it.
Tap Storage or Storage and cache. You will see two buttons: Clear cache and Clear data. Tap Clear cache only — do not tap Clear data, which removes login information and saved settings. The cache will clear in a few seconds. Repeat this for any other apps that are giving you trouble.
Clear all cached data at once
If you want to clear cache across your entire phone in one step, open Settings and go to Storage (sometimes labeled Device care or Memory). Look for an option called Storage, Cached data, or Clean up. Tap it, then confirm when prompted.
This removes cached files from all apps at the same time. It takes longer than clearing a single app's cache, but the result is the same — temporary files are deleted, and your phone has more free space. This is safe to do regularly without affecting your apps or accounts.
Clear browser cache on Samsung Internet or Chrome
If your web browser is slow or you want to clear browsing history and cached web pages, the process is slightly different. Open Samsung Internet (or Chrome if you use that instead). Tap the three-line menu button in the bottom right corner.
Tap Settings, then Privacy. Look for Delete browsing data or Clear browsing data. A window will appear with checkboxes for Cookies, Cached images and files, and other options. Make sure Cached images and files is checked, then tap Delete. Your browser cache is now cleared.
What to do if clearing cache does not fix the problem
If an app still crashes or freezes after you clear its cache, the next step is to clear the app's data. Go back to Settings > Apps, find the problem app, tap Storage, and this time tap Clear data. This removes login information and saved settings, so you will need to sign back in the next time you open the app.
If clearing data does not help, try uninstalling and reinstalling the app. Open Settings > Apps, find the app, tap Uninstall, then download it again from the Google Play Store. This gives you a fresh copy of the app with no corrupted files.
How often to clear cache
There is no hard rule, but clearing cache once a month is reasonable for most people. If you notice your phone slowing down or storage running low, clear cache sooner. Some people clear cache weekly as routine maintenance, while others only do it when they notice a problem.
Clearing cache is completely safe to do as often as you want — it will not damage your phone or cause data loss. The only minor downside is that apps may load slightly slower the first time you open them after clearing cache, since they have to rebuild their temporary files.
Frequently Asked Questions
Will clearing cache delete my photos or messages?
No. Cache is only temporary data that apps use to load faster. Your photos, messages, contacts, and accounts are stored separately and are not affected by clearing cache.
What is the difference between clearing cache and clearing data?
Clearing cache removes temporary files only. Clearing data removes temporary files plus your login information, saved settings, and app preferences. Always clear cache first; only clear data if the app is still broken afterward.
Can I clear cache without going into Settings?
Some Samsung phones have a built-in cleaning tool in the Device Care app. Open Device Care, tap Storage, and look for a Clean button. This clears cache and temporary files without opening Settings, though the Settings method gives you more control over which apps to clear.
Does clearing cache free up storage space?
Yes, sometimes significantly. Cached files can add up to hundreds of megabytes over time. If your phone is running low on storage, clearing cache is one of the fastest ways to free up space without deleting apps or photos.
Why does my app keep crashing even after I clear cache?
Cache is only temporary data. If clearing cache does not fix the problem, the app itself may be corrupted or outdated. Try clearing the app's data (not just cache), then uninstalling and reinstalling it from the Google Play Store.
