Is an app on your Android phone acting up, loading slowly or taking up more space than it should? Clearing the cache is one of the simplest and safest fixes. Cache files help apps load faster, but over time they can grow large or become corrupted, causing glitches. This guide explains what cache is, how to clear cache on an Android phone for individual apps and the Chrome browser, the difference between clearing cache and clearing data, steps for popular brands and when clearing cache actually helps.
Menu names vary by Android version and manufacturer, but the steps below work on most phones.
What is cache on Android?
Cache is temporary data that apps and websites store on your phone to load faster next time. For example, a social media app might cache images and videos you have already viewed, and a browser caches parts of websites.
Cache is meant to be helpful, but:
- It can take up a lot of storage, especially for streaming, social and messaging apps.
- Corrupted cache can cause crashes, freezing or display problems.
- Old cache may show outdated content.
Clearing cache is safe: apps rebuild it as needed. You will not lose your login, settings or personal files by clearing cache alone.
Clear cache vs clear storage (data)
| Option | What it removes | What you keep | Use when |
|---|---|---|---|
| Clear cache | Temporary files | Logins, settings, saved data | App is slow, glitchy or using too much space |
| Clear storage or clear data | Everything the app stored, including settings and offline files | The app itself | App still broken after clearing cache, or you want a fresh start |
Clearing storage is like reinstalling the app. You will need to sign in again, and offline downloads may be deleted.
How to clear cache for one app (most Android phones)
- Open Settings.
- Tap Apps (sometimes Apps and notifications).
- Tap See all apps if needed, then select the app.
- Tap Storage and cache (or Storage).
- Tap Clear cache.
Samsung Galaxy phones
- Open Settings, then Apps.
- Select the app.
- Tap Storage.
- Tap Clear cache at the bottom.
Google Pixel phones
- Open Settings, then Apps.
- Tap See all apps and choose the app.
- Tap Storage and cache.
- Tap Clear cache.
How to clear cache in Chrome on Android
- Open Chrome.
- Tap the three dots in the top-right corner.
- Tap Delete browsing data (or History, then Clear browsing data).
- Choose a time range, such as All time.
- Check Cached images and files.
- Uncheck Cookies and Saved passwords if you want to stay signed in.
- Tap Delete data.
Clearing cookies signs you out of most websites, so choose carefully.
Can you clear all app cache at once?
Newer versions of Android removed the one-tap “clear all cached data” option. Some manufacturers include device care tools:
- Samsung: Settings, Device care (or Battery and device care), then Storage, where you can review large files and apps.
- Pixel: Settings, Storage, then review apps and files, or use the Files by Google app to clean junk files.
Avoid third-party “cleaner” or “booster” apps that promise to speed up your phone. Many show ads, collect data or offer little benefit.
Which apps benefit most from clearing cache?
| App type | Why cache grows |
|---|---|
| Social media (Instagram, TikTok, Facebook) | Images and videos |
| Messaging (WhatsApp, Telegram) | Media previews |
| Streaming (YouTube, Spotify) | Thumbnails and temporary media |
| Browsers (Chrome, Samsung Internet) | Website files |
| Maps | Map tiles |
| Games | Assets and updates |
When clearing cache helps
- An app crashes or freezes
- Images or pages do not load properly
- An app shows outdated content
- Storage is nearly full
- After a major app update causes glitches
When it won’t help
- Hardware issues like battery wear or overheating; see how to fix phone overheating
- Weak internet connections
- Problems caused by Android bugs that need a system update
- Apps that are poorly designed or incompatible with your phone
Other ways to free up storage on Android
- Delete apps you no longer use.
- Use Files by Google to find duplicates and large files.
- Back up photos to Google Photos and remove local copies with “Free up space.”
- Clear downloaded podcasts, music and videos.
- Move files to a microSD card if your phone supports it.

Real examples
The glitchy Instagram. Maya’s Instagram kept freezing on videos. Clearing the app’s cache fixed it without losing her login.
The full storage. Leo’s phone warned of low storage. Clearing cache for TikTok and YouTube freed over 2 GB.
The broken website. Ana saw an outdated version of a website in Chrome. Clearing cached images and files fixed it.
Frequently asked questions
Is it safe to clear cache on Android?
Yes. Clearing cache removes temporary files only.
Will clearing cache delete my photos?
No. Photos and personal files are not deleted by clearing cache.
How often should I clear cache?
Only when apps misbehave or storage is low. Regular clearing is unnecessary.
Why did my app slow down after clearing cache?
The app must rebuild its cache, so it may load slower at first.
What’s the difference between cache and cookies?
Cache stores website files; cookies store login sessions and preferences.
Clearing cache in other popular browsers on Android
| Browser | How to clear cache |
|---|---|
| Samsung Internet | Menu (three lines), Settings, Personal browsing data, Delete browsing data, select Cached images and files |
| Firefox | Menu, Settings, Delete browsing data, choose Cached images and files |
| Microsoft Edge | Menu, Settings, Privacy and security, Clear browsing data |
| Opera | Menu, Settings, Clear data, Cached images and files |
| Brave | Menu, Settings, Privacy and security, Clear browsing data |
In most browsers, you can choose to keep passwords and cookies so you are not signed out.
Clearing the system cache partition (advanced)
Older Android phones allowed you to “wipe cache partition” from recovery mode to clear system-level temporary files after a major update. Many newer devices, especially Pixel phones, no longer offer this option because of how modern Android updates work. Some Samsung models still include it. The process usually involves turning off the phone and holding a combination of buttons to enter recovery mode, then selecting “Wipe cache partition.” Be careful in recovery mode: do not choose “Wipe data/factory reset” unless you intend to erase your phone. If you are unsure, skip this step; clearing app caches is usually enough.
How cache affects storage over time
Cache usage varies widely. A heavy social media user might accumulate several gigabytes of cache across apps, while a light user might have only a few hundred megabytes. You can see how much space an app’s cache uses in Settings, Apps, [App], Storage and cache. Checking your top three space-heavy apps every few months is a quick way to keep storage under control.
Signs it’s time to do more than clear cache
If clearing cache does not fix a problem, try these steps in order:
- Force stop the app in Settings, Apps, [App], Force stop.
- Update the app from the Google Play Store.
- Restart your phone.
- Clear storage for that app (you will lose app data and need to sign in again).
- Uninstall and reinstall the app.
- Update Android in Settings, System, Software update.
- Contact the app developer through the Play Store listing.
These steps resolve most app problems without needing a factory reset.
Cache and privacy
Cached files can reveal which sites and apps you have used. If you share your phone or are concerned about privacy, clearing browser cache and history removes some of these traces. For more private browsing, use your browser’s incognito or private mode, which does not save history or cache after you close the tab. Keep in mind that private browsing does not hide your activity from websites, your employer or your internet provider. For more privacy on public networks, see best free VPNs for Android.
Quick summary
Cache is temporary data that helps apps and websites load faster. Clearing cache on Android is safe and can fix glitches and free up storage: go to Settings, Apps, choose the app, then Storage and cache and tap Clear cache. In browsers, delete cached images and files while keeping passwords. If problems continue, force stop, update, restart or clear storage. Avoid cleaner apps and use your phone’s built-in tools instead.
Final tip
Make a habit of checking Settings, Storage once a month. Android shows which apps and file types use the most space, so you can clear cache for the biggest offenders in a minute or two. This quick check keeps your phone running smoothly and helps you avoid the dreaded storage full warning.
The bottom line
To clear cache on an Android phone, go to Settings, Apps, choose the app, then Storage and cache and tap Clear cache. In Chrome, delete cached images and files from browsing data. Clearing cache is safe and can fix glitches and free up space, while clearing storage resets an app completely.
