Owners of a popular model Samsung Galaxy J7 often faced with a critical lack of free space. This problem is relevant for both versions with 8 GB and modifications with 16 GB of internal memory. Over time, the operating system becomes overgrown with temporary files, and modern applications require more and more resources for their work. Android becomes overgrown with temporary files, and modern applications require more and more resources to operate.
Lack of space leads to a slower interface, the inability to install updates, and failures of cameras or instant messengers. Luckily, there are many effective ways to optimize your storage without having to buy a new device. In this article, we will look at proven methods for freeing up space and expanding the capabilities of your gadget.
Analysis of the current state of memory
Before taking radical measures, you need to determine exactly what exactly is occupied by precious space. Built-in tools Android allow you to study the storage structure in detail. Go to the menu Settings and find the section Memory or Storage. The system will automatically analyze the data and display visual statistics.
Usually the lion's share is occupied by user files: photos, videos and music. However, often the hidden enemy is the cache of installed apps. Application cache can grow to gigabytes, especially for social networks and browsers. Understanding what exactly “eats” memory will help you choose the right cleaning strategy.
Pay attention to the “Miscellaneous” or “System Files” section. If this item takes up an abnormally large amount of space, the system may have accumulated remnants of deleted apps or erroneous logs. In this case, simply rebooting the device sometimes helps the system recalculate the amount of occupied space.
⚠️ Attention: Some system files may not display correctly immediately after a major firmware update. Give your phone a couple of hours for background optimization before you start cleaning.
Transferring applications to a memory card
One of the main advantages of the model Samsung Galaxy J7 is the presence of a slot for a microSD card. This allows you to physically increase the available data storage space. However, transferring the applications themselves has its own nuances depending on the version Android.
To move apps, open Settings, then go to the section Applications. Select the desired app from the list and press the button Storage. If the application developer has allowed the transfer, you will see an active button Change or Move to SD card.
- 📱 Social networks (VKontakte, Telegram) often support transfer, freeing up internal memory.
- 🎮 Heavy games usually allow you to move only part of the data (cache), leaving the main file in the system.
- 📸 System utilities and Google services most often block transfer for stable operation.
If the transfer button is inactive (gray), it means that the developer has disabled this function. In such cases, only deleting the application or using special launchers helps, although the latter method requires obtaining root access, which may void your warranty.
☑️ Preparing a memory card
Clearing the cache and removing garbage
Regular cleaning of temporary files is the safest and fastest way to regain megabytes of freedom. Smartphones Samsung have a built-in utility for servicing the device. It automatically finds unnecessary files and offers to delete them with one click.
Deeper cleaning is performed through the Recovery menu. To do this, turn off the phone, then hold down the key combination Volume Up + Home + Power. In the menu that appears, select Wipe Cache Partition. This operation is safe for your personal data, it deletes only the system update cache.
Recovery menu:1. Volume Down - select item
2. Power button - confirmation
3. Wipe Cache Partition - clearing the cache
It is also worth manually going through the folders in Explorer. Often in the root of memory there are folders from long-deleted games with names like Android/obb or Android/datacontaining the “tails” of apps. Removing such remnants can free up several gigabytes.
⚠️ Attention: When manually cleaning folders, do not delete files with the .xml or .db extension if you are not sure of their purpose - this may lead to resetting application settings.
Use the "Clear all" function in the "Device Maintenance" section once a week to maintain optimal speed for your Samsung J7.
Setting up the camera and multimedia
Media files are the main consumers of memory on any smartphone. The camera Samsung J7 by default can shoot in high resolution, which quickly fills up storage. Optimizing shooting settings will help save space without noticeable loss of quality for social networks.
Go to the Camera application and open the settings (gear icon). Find the item Image size and change it from maximum to optimal, for example, 5 MP or 8 MP. For publishing on Instagram or sending in instant messengers, this resolution is quite enough.
| Settings | Standard value | Optimized value | Save space |
|---|---|---|---|
| Photo resolution | 13 MP | 5-8 MP | up to 60% |
| Video quality | Full HD (1080p) | HD (720p) | up to 50% |
| Geolocation | On | Off | Insignificant |
| Video format | MP4 (high bitrate) | MP4 (medium) | up to 30% |
It is also recommended to enable the function automatic uploading of photos to cloud storage (for example, Google Photos or Yandex.Disk) with subsequent deletion of the originals from the device. This creates the effect of endless memory, since the files are stored on the server, and only thumbnails remain on the phone.
⚠️ Attention: The camera settings interface may differ depending on the firmware version (Android 6.0, 7.0 or 8.0). If you do not find the item you need, check system updates.
How does cloud deletion work?
When you enable the “Free up space” function, the application checks whether photos have been uploaded to the cloud. If so, it deletes the original from the phone, leaving behind a blurry thumbnail. When you click on a photo, it is quickly downloaded from the Internet.
Using the Adoptable Storage function
In some firmware versions for Samsung a function is available that allows you to combine the internal memory and microSD card into a single space. This is called Adoptable Storage. When this option is activated, the memory card is formatted and encrypted, becoming an integral part of the system.
To check the availability of this function, insert the memory card, go to Settings → Memory. Click on the name of your card and select Memory settings. If there is an item Use as internal memory, you are in luck. After formatting, all new applications and data will be written to the card by default.
However, this method has a serious disadvantage: if the card If the memory fails or you remove it, all applications installed on it will stop working, and data may be lost. In addition, the speed of the phone may be reduced if the card has a low speed class.
Memory consolidation (Adoptable Storage) is a radical method that turns the SD card into a system partition, but makes it unsuitable for use in other devices without formatting.
Reset to factory settings
If none of the The above methods did not help to radically solve the problem, the last option remains - a complete reset of the device. This procedure will return the phone to the state it was in when purchased, deleting all user data, accounts and applications.
Before starting the operation, it is critical to create a backup copy of all contacts, photos and documents. Use the service Samsung Cloud or connect your phone to your computer via a USB cable. After saving the data, go to Settings → General settings → Reset → Reset data.
After rebooting, you will get a clean system with the maximum amount of free memory. It is recommended to immediately set up automatic uploading of photos to the cloud and install only the necessary applications so that the problem does not recur in the near future.
Is it possible to increase the physical memory of the Samsung J7 without an SD card?
No, it is impossible to increase the memory physically soldered on the board. Memory chips are soldered into the motherboard, and replacing them at home is impossible without professional equipment and skills in soldering BGA chips.
Why is the memory not freed up after deleting applications?
Often this is due to the fact that only the shortcut or the main part of the app is deleted, while the cache and data folders remain in the system. You need to use the "Clear Cache" function or delete leftovers manually through the file manager.
Is it safe to use cleaner applications from the Play Market?
Most popular applications (for example, Clean Master) are safe, but often contain advertising and can aggressively close background processes, which reduces battery life. Samsung's built-in tools are usually sufficient for normal operation.
Does full memory affect the speed of the Samsung J7?
Yes, critically. When free memory remains less than 10%, the system begins to experience difficulties with creating temporary files and swapping, which leads to severe interface slowdowns and application crashes.
