How to Check Storage Space on Your Samsung Galaxy S21 Plus

If you’re curious about your available storage on the Samsung Galaxy S21 Plus, checking it is simple. Knowing your free space helps prevent issues like slowdowns or failed downloads. Follow these easy steps:

1. Open the Settings app on your Galaxy S21 Plus. You can find this icon on your home screen or app drawer—it looks like a gear.

3. Tap on “Storage”. Here, you’ll see a visual breakdown of your device’s memory usage, including used and available space.
4. Review the storage details. You will see categories such as Apps, Photos, Videos, and Other Files, which indicate what is occupying your storage.

If needed, tap on specific categories like “Apps” or “Images” to see which files or applications are taking up the most space. This allows you to decide what to delete or transfer to free up storage.

Additionally, the Storage menu provides options to delete unnecessary files directly. You can clear cache, uninstall unused apps, or delete old photos and videos to optimize free space.

Remember to regularly check your storage, especially before large downloads, updates, or new app installations, to ensure your Galaxy S21 Plus continues to run smoothly without running out of space.

Understanding Internal Storage and MicroSD Card Options

It’s helpful to understand the storage options available on your Galaxy S21 Plus. These include internal storage—fixed, built-in space—and removable MicroSD cards, which expand storage capacity. Knowing how each works assists in managing your files effectively and choosing the right setup.

Internal storage is the non-removable space built into your device, used to store apps, photos, videos, and other data. The Galaxy S21 Plus generally offers variants with 128GB, 256GB, or more. This storage type offers fast access and high reliability but cannot be expanded or removed. Managing this space is crucial if you have many files.

MicroSD cards are external storage options that you can insert to increase available space. They are especially useful for storing large media files like videos and photos. Note that not all Galaxy S21 Plus models support MicroSD cards. Always check your device specifications before purchasing one.

Here’s a quick comparison:

Feature	Internal Storage	MicroSD Card
Expandable	No, fixed storage	Yes, removable
Speed	Fast, optimized for the device	Depends on the quality of the card
Ease of Use	Builtin, no additional action needed	Requires insertion and formatting
Cost	Included in device purchase	Additional expense but offers flexibility

Assess your storage needs by considering how much space your apps, photos, and videos require. If you often run out of space, a MicroSD card could be an ideal solution. If your internal storage is sufficient, regular management can keep your device running well.

Note that some Galaxy S21 Plus models do not support MicroSD cards. Always verify your model’s specs or check in the Storage settings. Selecting a high-quality MicroSD card with fast read/write speeds can improve performance when expanding storage.

To transfer files, use a card reader connected via USB. Be careful when removing or inserting the MicroSD card to avoid data loss. Proper management of these options helps maintain your device’s efficiency and keeps your files safe.

Tips to Free Up Space on Your Galaxy S21 Plus

If your Galaxy S21 Plus is low on storage, don’t worry. Apps, photos, and files can accumulate quickly, causing slowdowns or errors. The good news is that you can free up space with some simple steps:

1. Delete Unnecessary Files and Photos

   Review your media using the Gallery app. Back up important photos or videos to cloud services like Google Photos or Samsung Cloud before deleting them from your device. Also, check the Files app for downloaded files and remove anything no longer needed.

2. Clear App Cache and Data

   Apps often store temporary cache files that can occupy significant space over time. To clear cache, go to Settings > Apps. Tap on an app, then select Storage. Tap Clear Cache. Repeat this process for apps that store large cache files. Be cautious when clearing data, as it resets app settings and may delete stored info.

3. Uninstall Unused Apps

   Review your installed applications and uninstall those you no longer use. In Settings, go to Apps, select an app, then tap Uninstall. Alternatively, long-press the app icon and drag it to the uninstall option. Removing apps frees up storage space and helps keep your device organized.

4. Use Storage Management Tools

   Your Galaxy S21 Plus offers built-in tools like “Device Care” to help manage storage. Navigate to Settings > Device Care > Storage. Tap Clean Now to automatically remove residual, unused, or large files, freeing significant space quickly.

5. Manage Media Files with Cloud Storage

   Upload photos and videos to cloud services like Google Photos, OneDrive, or Dropbox. After confirming successful uploads, delete local copies to free up space. This keeps your media safe and your device less cluttered.

6. Be Cautious with Overused Apps and Features

   Apps such as social media or messaging platforms often automatically store media and conversation histories. Regularly clear chat histories and disable auto-download options for images and videos. This prevents unnecessary buildup of stored data.

Implementing these tips will help maintain ample storage on your device, improve performance, and extend its lifespan. Make storage management a routine part of your device upkeep for optimal operation.

Manage and View App Storage Effectively

To keep your device running efficiently, manage app storage regularly and review how much space each app consumes. Apps often store cached files, downloads, and user data that can slow down your device or fill storage unnecessarily.

1. Access your device’s storage settings. Usually, go to Settings > Storage or Device Care. On computers, open File Explorer or Finder and go to storage options.
2. Find the section labeled Apps or Applications. This displays all installed apps and their storage usage.
3. Select an app to see detailed storage data, such as App Data, Cache, and Documents & Files. Cached files are often safe to clear and can free space.

How to Clear App Storage and Cache

1. Tap or click on the desired app. You will see options like Clear Cache and Clear Data.
2. Choose Clear Cache for a quick way to remove temporary files that often amount to several megabytes or more.
3. Use Clear Data if you want to erase all app data, including settings and saved files. Be cautious as this might require re-login and reset personalized preferences.
4. On computers, delete specific app folders or use system cleaning tools following your OS instructions to clear cache.

Tips for Optimizing Storage

• Review app storage periodically to prevent clutter.
• Uninstall apps you no longer use to free space and reduce background activity.
• Transfer large files such as videos and photos to cloud services or external drives.
• Back up important data before clearing app data to avoid losing essential information.
