If you still experience problems after you clear your system cache and browser cache, you may have to clean up your Android phone another way. If the problem persists, check for and remove any viruses or Android ransomware that may be infecting your device.
If you’re on PC, check out our complete guide to cleaning up and speeding up your PC. And if you have an Apple device, here’s how to clear your Mac cache and how to speed up your iPhone.
How to clear your app cache on Android
Clearing phone cache is easy on Android. The temporary files stored in your app cache are a great place to start. Here’s how to clear your app cache on Android:
Open Settings on your Android device and tap Battery and device care.
Tap Memory followed by Apps not used recently.
Select an app from the list. Search through the app list to clear your YouTube cache, Facebook cache, or even your Instagram cache.
After tapping a particular app, select Storage within App info.
Tap Clear cache at the bottom of the screen.
How to clear app data on Android
To free up even more space on your phone, wipe app data too. This will delete all user data stored within an app, not just the temporary cache files. The app itself won’t be deleted, but it will be reset, meaning you’ll need to sign in again and set any preferences.
Here’s how to clear app data on Android devices:
Open Settings and select Apps.
Tap on the app you want to clear app data for and select Storage.
Tap Clear data.
How to clear your Samsung app cache
Clearing app cache on Samsung phones is quick and easy. Here’s how to clear your app cache on a Samsung phone:
Open Settings and select Apps.
Find the app you want to clear, select it, and tap Storage.
Tap Clear cache.
If you want to delete all the data connected to that app, tap Clear data and then OK. Note that clearing data includes any files, settings, or account info you may have connected to that app.
Clearing your Android app cache can help fix speed issues and free up storage space. If you need more storage, clear the cache of the apps that take up the most space. Clearing your app cache every few months will help streamline your phone and keep it from getting too full.
Clearing your cache can also get rid of unsafe apps that have been consuming your mobile data. Be careful which apps you give permission to, and check out our guide to reducing mobile data usage if you find yourself constantly low on data.
What happens when you clear cache data on Facebook, Instagram, or YouTube? Clearing the cache on your social media apps gets rid of temporary files such as liked photos or half-watched videos. So unless you need to reference this data, it’s fine to delete it.
Your important account details are saved in the cloud. But after clearing the cache for a particular app, you will have to log in again. So before clearing the app cache on your favorite apps, make sure you know your username and password — or create a new, strong password by clicking the reset password link.

How to clear Chrome browser cache on Android
If you use Chrome on your Android phone or tablet, clearing your Chrome cache should speed up your browsing and give you more space. The process should be the same if you use a Samsung phone or any other Android device.
Here’s how to clear the Chrome cache on Android:
Tap the three vertical dots in the upper-right corner.
Tap Clear browsing data…
Tick the Cached images and files box. If you want to delete your cookies or clear your search and browsing history, check those boxes as well.
Select a time range on the upper-right. Choose All time to make Android clear all the cache from Chrome. Then tap Clear data.
That's how you clear your Chrome cache on Android. Clearing your Chrome cache is the same on PC and mobile, so use these same steps to clear your Chrome cache on your computer.
If you use Chrome’s Incognito mode, Android will clear the Chrome cache automatically after you end your session. But if you want to keep your internet history hidden from marketers or even cybercriminals, use a secure and private browser.
If you want to keep your activity secret from nosey family or friends, hide your Android apps in secure folders. You can further customize your browsing experience by either blocking or allowing pop-up ads.
Periodically clearing your Android cache is good browsing hygiene. As well as keeping your browser neat and tidy, cleaning your browser makes it safer by keeping sensitive information from hanging around too long.
Messaging apps store personal info too, so use the best privacy apps for Android to keep your private conversations private and to help prevent phone spoofing.
Clear cache for social media (Facebook and Instagram)
When clearing phone cache, you may notice that social media apps are some of the main culprits for hoarding temp files that swamp your storage. Clearing cache on Android social media apps is just as quick and easy as it is for other apps.
Here’s how to find delete cached data for YouTube, Facebook, Instagram, and other social media apps:
Go to Settings and select Apps to display a list of installed apps.
Select YouTube to clear YouTube cache, Facebook to clear Facebook cache, or Instagram to clear Instagram cache. Then tap Storage.
Tap Clear cache.
What are hidden cache files?
Android’s hidden cache saves pictures, files, and other scripts from apps and websites you visit frequently so that you don’t have to download these files again every time you visit. This helps apps and websites load faster, but over time cache data can build up and clog your device.
Android’s hidden cache is like carrying around extra weight that makes your phone or tablet work harder. Clearing the cache can help extend the battery life of your Android device.
How to clear your hidden app cache on Android
To clear hidden Android cache, follow the same simple process for deleting app cache for specific third-party apps. This will clean up all the cached data for that particular app, hidden or otherwise.
Here’s how to clean hidden cache on Android:
Open device Settings, and select Apps.
Find the app you want to clear app data for, tap it, and select Storage.
Tap Clear cache to delete all cached data for the selected app.
Repeat the process for other apps to continue clearing hidden app cache.
What happens when you clear cache?
When you clear cache, the stored data of any app or browser that you clear is wiped out. That means apps and websites will load files (photos, videos, etc.) from the internet rather than retrieving them from your phone. Critical details related to the app’s or website’s essential functions will remain, such as your settings, contacts, or messages.
Like cleaning your closet, getting rid of junk files gives you more space for the things you actually need. It can free up more room for RAM and also stop data hounds from tracking your smartphone.
How often should you clear cache on an Android phone?
You should clear cache on your Android phone every few months. Clear the app data for Android apps that are behaving erratically, such as not loading correctly or closing unexpectedly. And clear the Chrome cache when Chrome is more sluggish than usual.
And don’t forget to update your phone regularly.
