How do I check how much storage is left on my Firestick?

Go to "Settings > My Fire TV > About > Storage". The screen shows how much space is used and how much is left.

Is it safe to clear cache on Firestick?

Yes, clearing the cache is safe. It only removes temporary files, and the app rebuilds them as needed. You stay signed in.

What is the difference between clear cache and clear data on Firestick?

Clear cache removes temporary files only. Clear data resets the app completely, including your settings and logins.

Why can't I uninstall some apps on my Firestick?

Some apps are system apps that the Fire TV needs to work. They have no "Uninstall" button, but you can still clear their cache.

Does uninstalling an app on Firestick delete my login?

Yes. When you reinstall the app, you will need to sign in again and set up your preferences.

How often should I clear my Firestick cache?

Once a month is enough for most people. Clear it sooner if the stick feels slow or shows a storage warning.

Will a factory reset clear all Firestick storage?

Yes. A factory reset erases all apps, files and logins and returns the stick to how it was when new. Use it only when nothing else works.

Firestick storage full? How to clear space & uninstall apps 2026

If your Firestick storage is full, start by clearing the cache of your biggest apps. Then uninstall apps you no longer use and delete old install files. Restart the stick when you are done. It takes about 10 minutes, and you only need your remote.

What You Need Before You Start

Your Fire TV Stick remote with working batteries.
A short list of the apps you want to keep.
Your app logins, because some steps sign you out.
About 10 to 15 minutes.

Step-by-Step: Clear Space and Uninstall Apps on Your Fire TV Stick

Follow these steps in order. Menu names can change a little between Fire OS versions, but the path is close on all recent models.

Press the Home button on your remote.
Open "Settings > My Fire TV > About > Storage" to see how much space is left.
Press Back until you reach the main Settings screen.
Open "Settings > Applications > Manage Installed Applications".
Look at the size shown for each app, and start with the biggest one.
Select the app and choose "Clear cache". The cache is a folder of temporary files that an app saves so it loads faster. Clearing it is safe.
Do the same for every large app, especially video players like TiviMate or Kodi.
If an app is still very large, choose "Clear data". This resets the app to day one, so you will need to sign in again.
Find an app you never use, select it, and choose "Uninstall".
Confirm by selecting "Uninstall" again on the next screen.
Open the file manager or download app you used to install apps, and delete old APK files. An APK is the install file for an Android app. Once the app is installed, you do not need the APK file anymore.
To stop apps from growing on their own, turn off automatic updates in "Settings > Applications > Appstore > Automatic Updates".
Restart the stick with "Settings > My Fire TV > Restart".
Check your space again in "Settings > My Fire TV > About > Storage".

Which Cleanup Method Should You Use?

Each method removes a different kind of file. This table shows which one to pick.

Method	What it removes	Space you get back	Do you lose logins?	Best time to use it
Clear cache	Temporary app files	Small to medium	No	First step, every time
Clear data	All app settings, logins and saved files	Medium to large	Yes	When one app stays huge after clearing the cache
Uninstall	The whole app	Large	Yes, for that app	Apps you have not opened in weeks
Delete APK files	Old install files	Small to large	No	After installing apps from outside the Appstore
Factory reset	Everything on the stick	All of it	Yes, every login	Last resort only

If a Step Fails

Most problems have a quick fix. Find yours below.

"Clear cache" is grayed out

The app has no cache saved right now. Move on to the next app on your list.

There is no "Uninstall" button

This is a system app. Amazon needs it to run the stick, so you cannot remove it. Clear its cache instead.

Storage is still full after the restart

Go back to "Settings > Applications > Manage Installed Applications". Look for a player app with a lot of saved data and use "Clear data" on it. Then sign in again.

The stick gets stuck during an uninstall

Unplug the power cable and wait 30 seconds. Plug it back in and try again once the stick has started up.

Nothing works

Use "Settings > My Fire TV > Reset to Factory Defaults". This erases all apps and logins, so write down your account details first.

Why Firestick Storage Fills Up So Fast

A Fire TV Stick has very little built-in storage compared to a phone. A good part of it is taken by the system itself. Only a small amount is left for your apps.

Several things eat that space over time:

App updates. Each update can make an app bigger.
Cache build-up. Video players save thumbnails, guides and logos.
Leftover APK files. These stay on the stick after you install an app.
Apps you tried once. They sit there and keep taking space.

New shows and apps come out all the time. Entertainment sites like Collider cover a steady stream of releases, and it is easy to want to try everything. But every new app takes a piece of your limited space.

How to Keep Your Firestick Storage Clean in 2026

A few simple habits stop the "storage full" warning from coming back.

Clear the cache of your main apps once a month.
Keep only one video player app, not three or four.
Delete each APK file right after you install the app.
Uninstall any app you have not opened in a month.
Check "Settings > My Fire TV > About > Storage" every few weeks.

Streaming hardware keeps changing every year. If you want to follow the bigger picture on devices and tech companies, Bloomberg Tech is a good place to start.

Pick one player app and set it up well

Many people keep TiviMate, Kodi and IPTV Smarters Pro all on one stick. That uses up space quickly. Choose the one you like best and remove the others.

Inside your player, look at the buffer setting. A buffer is a small piece of video that loads ahead so playback does not stop. A buffer of 5,000 ms (five seconds) is a good balance for smooth viewing.

Fix stutter that is not caused by storage

Low storage can make your stick slow. But stutter can also come from your internet provider slowing down video traffic. This is called throttling. Using Cloudflare DNS (1.1.1.1) can help with this. DNS is the service that turns web addresses into numbers your device can connect to.
