Three Samsung Android phones lined up on a white background, showing the kind of device this cache-cleaning guide applies to in everyday use.
Clearing the cache on Android is one of the safest maintenance tasks you can perform on your phone, because it removes temporary files without touching your photos, messages, accounts, or personal settings.
If an app has started crashing, freezing, loading slowly, or showing outdated content, a stale or corrupted cache is often the culprit, and clearing it gives the app a clean set of temporary files to rebuild.
This guide walks you through the exact steps for individual apps, for the Chrome browser, and for the small differences between Samsung, Pixel, and other Android phones.
Before you tap anything, it is worth understanding the one distinction that matters most, which is the difference between clearing cache and clearing data, because the two buttons sit side by side and do very different things.
Clearing cache only deletes temporary files that the app can recreate on its own, while clearing data resets the app completely, signs you out, and deletes settings and offline content that was never synced.
Follow the steps below in order, start with the app that is misbehaving, and you will free up storage and fix common glitches without losing anything important.

What Is Cache on Android?
A cache is a collection of temporary files that an app stores on your phone so it does not have to download or generate the same content again every time you open it.
A social media app, for example, keeps copies of profile pictures and images you have already viewed, a music app keeps parts of songs you have streamed, and a browser keeps website logos and page elements that rarely change.
The next time you return, the app loads those files from local storage instead of fetching them over the internet, which makes everything feel faster and uses less mobile data.
The trade-off is that cached files accumulate quietly in the background, and on a phone used daily they can grow from a few megabytes into hundreds of megabytes, or even more than a gigabyte for heavy social and streaming apps.
Most of the time that is harmless, because Android can reclaim cached space automatically when storage runs low, but a cache can also go stale, meaning the app keeps showing an old version of a page, or corrupted, meaning a damaged file makes the app crash or freeze.
Clearing the cache forces the app to download fresh copies, which is why it is such a reliable first step when something feels off.
It also helps to know that clearing the cache does not make your phone permanently faster in the way a hardware upgrade would, because the cache will simply rebuild itself as you use the app again.
That rebuilding is normal and expected, and the first launch after a clear may even feel slightly slower while images and data reload.
The real benefit is fixing glitches, removing outdated files, and freeing a useful chunk of storage for a short while, not permanently shrinking every app to zero.
Cache vs Data: The Difference That Matters
The confusion between these two options causes more accidental data loss than almost any other Android setting, so take a moment to learn them before you start tapping buttons.
Clear cache removes only temporary files, such as thumbnails, preloaded content, and temporary databases, and it keeps your account, your settings, your saved files, and your login sessions exactly as they were.
Clear data, which is labelled Clear storage on Pixel phones, removes everything the app stored on your device, including its cache, and returns the app to the state it was in when you first installed it.
| Action | What it removes | What it keeps |
|---|---|---|
| Clear cache | Temporary files only, such as thumbnails and preloaded content | Logins, settings, saved files, and offline content |
| Clear data / Clear storage | Everything the app stored locally, including cache, settings, and logins | Nothing on the device; the app behaves like a fresh install |
Put simply, clearing data signs you out of the app, wipes your preferences, deletes offline downloads such as saved songs or maps, and can erase local progress or files that were never backed up to the cloud.
Your account itself is not deleted, and anything synced to a server can usually be restored by signing in again, but anything stored only on the phone may be gone for good.
That is why every guide, including Android's own documentation, recommends starting with Clear cache and only considering Clear data as a last resort when the app still misbehaves after a restart and an update.
Clearing cache, by contrast, does not delete your photos, your messages, your contacts, your account logins, or your personal data, because those are stored as app data or in separate folders, not as cache.
If a website or app asks you to sign in again right after you cleared only the cache, something else changed, such as cookies being deleted in a browser, or the app itself refreshing its session for another reason.
For a normal app, you should stay signed in after a cache clear, which makes it a safe routine task you can repeat whenever an app starts acting strangely.
How to Clear Cache for One App
Android does not offer a single built-in button that clears every app's cache at once on modern versions, a change that arrived with Android 8, so the reliable method is to clear the cache app by app, starting with the one causing trouble.
The steps below work on most Android phones running recent versions, with only the name of one screen varying by brand, and the whole process takes less than a minute per app once you know where to look.
Open the Settings app on your Android phone, then tap Apps to see the list of installed apps, and on a Pixel phone tap See all apps if the app you want is not shown immediately.
Find the app that is crashing, freezing, or taking up too much space, either by scrolling through the list or by using the search icon at the top of the Apps screen to type its name.
Tap the app name to open its App info page, where you will see options for notifications, permissions, and storage, along with buttons to force stop or uninstall the app if needed.
Tap Storage on a Samsung phone, or Storage & cache on a Pixel or stock Android phone, to open the storage screen that shows how much space the app uses for data and for cache.
Tap Clear cache and watch the cache figure drop to zero or close to it, then leave the neighbouring Clear data or Clear storage button alone unless you deliberately want to reset the app completely.
Open the app again and check whether the problem is gone, remembering that the first launch may take a little longer while the app rebuilds the temporary files it needs for normal use.
Repeat the same steps for any other app that is misbehaving, but resist the urge to clear the cache of every app on the phone, since that only forces everything to reload at once for no real benefit.
A useful shortcut exists on many phones if you do not want to dig through Settings, which is to long-press the app icon on your home screen or app drawer and tap the App info icon, usually a small circled letter i, to jump straight to the same App info page.
From there, the Storage screen and the Clear cache button are exactly the same, so you can fix a misbehaving app in a few seconds without remembering the full Settings path.
This shortcut is especially handy when an app keeps crashing as soon as you open it, because you never need to launch the app itself to reach its storage settings.
Samsung, Pixel, and Other Android Phones
The core steps are the same everywhere, but manufacturers rename menus and add their own cleaning tools, so the table below shows the path you are most likely to see on the major brands.
If your phone uses a different skin, look for the same two ideas in different words, namely an Apps list in Settings and a Storage screen for each individual app, because every Android phone has both.
| Phone or brand | Path to Clear cache |
|---|---|
| Google Pixel / stock Android | Settings > Apps > See all apps > app name > Storage & cache > Clear cache |
| Samsung Galaxy (One UI) | Settings > Apps > app name > Storage > Clear cache |
| Xiaomi / Redmi / POCO (MIUI) | Settings > Apps > Manage apps > app name > Clear data > Clear cache |
| OnePlus / OPPO / Realme | Settings > Apps > App management > app name > Storage usage > Clear cache |
Samsung owners also have an extra option in Device Care, where Settings, then Battery and device care, then Storage, shows a storage overview and a Clean now option that can clear cached files for multiple apps in one pass.
That tool is convenient when storage is genuinely tight, but it is still worth checking the individual app first when you are troubleshooting a single crash or freeze, because a targeted cache clear tells you whether that app was really the problem.
On Pixel phones, Settings, then Storage, then Apps gives a similar overview of which apps use the most space, which helps you spot the biggest cache hogs before you start clearing anything.
One more brand difference worth knowing is that some manufacturers ship a separate cleaner or optimiser app, such as Xiaomi's Security app or Huawei's Optimizer, which can also remove cache files in bulk.
These tools are safe when they only clear cache, but be cautious with any cleaner that promises to boost speed by killing apps or deleting files you do not recognise, and never grant a third-party cleaner permission to delete data you have not checked first.
The built-in Settings method remains the most transparent option, because you can see exactly which app you are cleaning and how much space its cache occupies before and after.
How to Clear the Chrome Cache on Android
Your browser keeps its own cache, separate from the cache of other apps, so clearing an app's cache in Settings does not clear Chrome's cached web pages, and vice versa.
Chrome is often the biggest cache on a phone because every site you visit leaves behind images and page elements, so it deserves its own steps, and the key trick is to select only Cached images and files so you stay signed in to your favourite sites.
Open Chrome on your Android phone, then tap the three-dot menu in the top-right corner of the screen to open Chrome's main menu options.
Tap Delete browsing data in the menu, then tap More options if it appears, so you can choose exactly which types of data Chrome will remove.
Choose a time range at the top, and select All time if you want to clear the entire browser cache rather than only the most recent hours or days.
Tick only Cached images and files, and leave Cookies and site data, Browsing history, and Saved passwords unticked, because ticking cookies would sign you out of most websites.
Tap Delete data or Clear data at the bottom of the screen, confirm if Chrome asks, and then reload the site that was showing outdated content to check whether it now loads correctly.
If you use Samsung Internet instead of Chrome, the idea is identical but the menu names differ slightly, so open Samsung Internet, tap the menu icon, then Settings, then Personal browsing data, then Delete browsing data, and select only Cached images and files before tapping Delete data.
The same caution about cookies applies here too, because deleting cookies will sign you out of websites, while deleting only cached images and files simply forces sites to download fresh copies of their pictures and page elements.
For any other browser, look for a similarly named Clear browsing data or Delete browsing data option in its Settings or Privacy menu, and always check which boxes are ticked before confirming.
What to Do If Storage Is Still Full
Clearing the cache frees space, but it is not a magic fix for a phone that is genuinely full, because the cache will rebuild and the underlying storage pressure will return.
If your phone still warns about low storage after clearing the biggest caches, the next step is to find what is really using the space, which you can do in Settings, then Storage, where Android breaks usage down by apps, photos and videos, audio, and system files.
Large games, downloaded videos, and years of photos are far more common culprits than cache, so deleting a few unused apps or moving photos to a cloud backup usually frees far more space than any cache clear ever will.
Before you take stronger action, try the simple troubleshooting ladder in order, because each step is safer than the one after it and often solves the problem on its own.
Restart your phone first, since a restart clears temporary system state and can resolve a one-off freeze, then check the Play Store for an update to the misbehaving app, because a buggy cache problem is often fixed by the developer in the next release.
If the app still crashes, force stop it from its App info page, clear its cache again, and only then, as a final step, consider clearing its data, and only after you have confirmed that anything important is synced or backed up elsewhere.
There is also an advanced option called wiping the cache partition from Recovery Mode, which clears system-level temporary files without deleting personal data, but it is rarely needed on modern Android phones and the button combination varies by manufacturer.
Unless your whole phone is misbehaving rather than a single app, or your manufacturer specifically recommends it, skip Recovery Mode and stick to the per-app method in this guide, because it is safer, simpler, and solves the vast majority of cache-related problems.
If even a full app reset does not help, uninstalling and reinstalling the app is usually the cleaner next step, followed by contacting the app developer if the issue persists across reinstalls.
Tips for Keeping Your Cache Under Control
Good cache habits are boring in the best possible way, because they prevent problems instead of fixing emergencies, and they take only a few minutes a month.
Check Settings, then Storage, then Apps once a month and clear the cache of only the two or three apps with the largest caches, especially social, video, and shopping apps that you open dozens of times a day.
That targeted approach keeps storage comfortable without forcing every app on your phone to reload all of its images at once, which is what happens when people clear everything indiscriminately.
It is equally important to avoid the temptation of aggressive third-party cleaner apps that promise to speed up your phone by constantly clearing caches and killing background processes.
Android already manages its cache intelligently, reclaiming space automatically when storage runs low, so a cleaner that runs all day can actually make your phone slower by forcing apps to rebuild their caches repeatedly and draining battery in the process.
A manual cache clear when an app misbehaves, plus the built-in storage tools from Google or Samsung, is all most people ever need, and it keeps you in control of exactly what gets deleted.
Finally, remember that cache is not the enemy, and a large cache on an app you use heavily is often a sign that the app is working as intended, storing files locally so it loads quickly and uses less data.
Judge an app by how it behaves, not by the size of its cache alone, and only intervene when you see a real symptom, such as repeated crashes, frozen screens, outdated pages, or a genuine low-storage warning.
With that mindset, clearing the cache becomes a quick, confident fix you can use whenever needed, rather than a ritual you perform out of worry every week.
Frequently Asked Questions
Will clearing cache delete my photos or messages?
No, clearing an app's cache does not delete your photos, messages, contacts, or personal files, because those items are stored as app data or in separate folders on your phone, not as temporary cache files.
The cache holds only copies of content the app can download or generate again, such as thumbnails and preloaded images, so removing it leaves your actual content untouched and your account still signed in.
Will clearing cache sign me out of the app?
No, clearing only the cache keeps you signed in, because your login session and account tokens are stored as app data, not as cache, and the cache clear does not touch them.
If you find yourself signed out, you probably tapped Clear data or Clear storage instead, or you deleted cookies in a browser, both of which do remove login information and require you to sign in again.
How often should I clear the cache on Android?
There is no need to clear cache on a fixed schedule, and doing it weekly for every app can actually slow things down by forcing constant reloading, so a sensible rhythm is once a month for the biggest apps, plus any time a specific app crashes, freezes, or shows outdated content.
If an app rebuilds a huge cache within days, check for an app update or a bug, because that pattern can signal a problem with the app itself rather than normal use.
Why does the cache fill up again so quickly?
The cache refills quickly because that is exactly what it is designed to do, since every image, video, and page element you view gets stored locally so the next visit loads faster and uses less mobile data.
Heavy users of social media and streaming apps can easily see a gigabyte of cache return within a week, which is normal, and only a single app growing far faster than similar apps is worth investigating as a possible bug.
Is it safe to clear cache for system apps?
Yes, clearing the cache of a system app is generally safe for the same reason as any other app, because it only removes temporary files that the system can rebuild, but you should still be careful to tap Clear cache and never Clear data on a system app you do not fully understand.
If you are unsure about a particular system app, leave it alone or search for its specific name first, because resetting system app data can change settings that are harder to restore than a normal app.
Clearing the cache on Android is a small skill that pays off again and again, because it fixes crashes, frees storage, and refreshes stale content without risking the data that actually matters to you.
Start with the app that is causing trouble, choose Clear cache and not Clear data, remember the Chrome trick of ticking only Cached images and files, and keep the monthly check to your biggest apps only.
With those habits in place, your phone will stay responsive, your storage will stay comfortable, and you will never again have to guess which button is the safe one.
