How to Clean Junk Files on Samsung Phones
The accumulation of files can quickly deplete your phone's storage capacity. It’s not uncommon for users to feel confused or frustrated when they receive a notification indicating that their phone’s internal storage is full. This situation can disrupt daily activities that rely on your device.
Deleting unnecessary files from your phone is not a difficult task, especially if you’re familiar with using such devices. However, some users may still struggle with how to properly delete files from their phone.
In this guide, I’ll explain how to delete junk files, particularly on Samsung phones. If you’re curious and want to learn more, let’s dive into the details below!
1. Using the Device Care Feature
Samsung phones come equipped with a handy feature called Device Care that helps optimize your device’s performance. This tool allows users to clean their phones quickly and easily, ensuring smooth operation. Follow these steps to use it:

1. Open Settings
Start by opening the Settings app on your Samsung phone. You can access it from the app menu or by swiping down the quick panel and tapping the gear icon, usually located in the top-right corner.
2. Select Device Care
Once in the Settings menu, scroll down and select the Device Care option. The Device Care page gives you an overview of your phone’s performance, including battery health, storage usage, memory status, and security features.
3. Tap "Optimize Now"
To clear junk files and enhance your phone’s performance, tap the Optimize Now button. This feature automatically analyzes your device, deleting unnecessary temporary files and cache data.
Using the Optimize Now button is the quickest and most effective way to clean up unwanted files while improving memory and battery efficiency.
2. Cleaning Internal Storage
After using the Optimize Now feature, you can explore the Storage section to get a detailed view of the files consuming your device's space.
On the Storage page, you’ll see an overview of your internal memory usage. It displays how much storage has been used and breaks down the types of files on your Samsung phone, along with the amount of memory each type occupies.
Interestingly, this page also allows you to perform more in-depth cleaning by removing unused files. There are four types of cleaning you can do:
Recycle Bin

The Recycle Bin serves as a temporary storage area for files you’ve deleted. Some apps, such as the Gallery, move deleted files to the Recycle Bin before permanently removing them after 30 days.
Using this feature, you can review and permanently delete files stored in the Recycle Bin. Here’s how to do it:
- Open the Recycle Bin
Navigate to the Recycle Bin option within the app you want to manage. For example, open the Gallery app and access its Recycle Bin feature. - Select Files to Delete
Browse through the files and press and hold the ones you want to delete permanently. - Delete the Files
Tap the Delete button to remove the selected files from the Recycle Bin permanently.
This process helps free up space on your device while ensuring that no unnecessary files remain in temporary storage.
Unused Apps

In this section, you can also see a list of apps that are rarely or never used. Deleting these apps can help free up more storage space, as well as reduce memory usage and battery power. Here's how:
- Select the Unused Apps option
- Select the app you want to uninstall
- Tap on Uninstall button
Duplicate Files

The Duplicate Files feature helps you identify and remove duplicate files in your storage. Deleting these duplicates can free up space and keep your storage organized.
This feature is particularly useful if you often receive the same files, such as images or documents, from different sources. Here's how to use it:
- Select the Duplicate Files option
- Select one of the files that has duplicates
- Press the Delete button to delete it
Large Files

Lastly, the Large Files feature helps you identify large files, such as videos, photos, or downloaded documents, that may no longer be necessary. These files can take up a lot of storage space, and often, they’re not required in the long run.
You can review and delete these files to free up space. Here’s how to do it:
- Select the Large Files Option
- Choose the Large File to Delete
- Tap the Delete button to remove the file.
Additionally, on this page, there’s a Move Files button that allows you to transfer large files to external storage, such as a USB drive (pendrive). This way, you can free up space on your device while keeping your files safe.
That wraps up the tutorial on cleaning junk files on Samsung phones. It’s recommended to perform this cleaning at least once a week to maintain optimal performance. Regular cleaning will help ensure that your phone stays in top condition.
