Over time, even the most productive gadget begins to work more slowly, responding to presses with a delay. Owners of branded devices Lenovo often encounter the fact that the system memory is filled with incomprehensible files, and applications crash. Cleaning the tablet it becomes necessary not only to free up gigabytes, but also to return the device to its former responsiveness. Ignoring system garbage can cause the interface to slow down even when performing simple tasks.
There are many optimization methods: from manually sorting files to radical measures like a complete reset. In this article we will look in detail at how to clean a tablet on an Android Lenovo using the built-in system tools and third-party utilities. It's important to understand the difference between safely clearing the cache and deleting system files that could disrupt the operation of the operating system. A competent approach will extend the life of your device without the need to contact a service center.
Built-in cleaning tools in the Lenovo shell
Modern firmware from the manufacturer already contains the necessary functionality for servicing the system. You do not have to download dubious apps from third-party sources, since a basic Phone Master or similar service is pre-installed on most models. This tool analyzes the state of the storage and offers to delete temporary files that are no longer needed for applications to work.
To start the process, you need to go to the settings and find the section responsible for maintaining the device. Typically the path looks like this: Settings → Memory and storage → Memory cleaning. The system will automatically scan the disk and show a list of files that can be safely deleted. Temporary files and the remnants of deleted applications make up the lion's share of this garbage.
However, automatic cleaning does not always removes everything unnecessary. Sometimes manual control is required, especially if you have not audited the downloaded files for a long time. The built-in tool is good for regularly maintaining cleanliness, but for deep optimization additional actions will be required.
Use the built-in “Cleaning” function once a week to prevent critical filling of the internal memory, which directly affects the speed of the tablet.
Manually clearing the cache and application data
Each installed application creates its own temporary files to speed up content loading. Over time, this application cache can grow to gigabytes, taking up valuable space. Unlike user data, the cache can be deleted without fear of losing important information, although the application may take a little longer to load when first launched after clearing.
To perform this procedure, go to the menu Settings → Applications → All applications. Choose the app that consumes the most space (often social networks, browsers or video services). Inside the application menu, find the “Storage” item and click the “Clear cache” button. If the problem is not solved, you can select “Clear data”, but this will return the application to the state immediately after installation.
Particular attention should be paid to instant messengers and galleries. B Telegram or Viber the cache can take up tens of gigabytes due to stored photos and videos. It is better to clean them through the settings of the application itself, using the “Memory Usage” function, where you can selectively delete media files for a certain period.
- 🗑️ Delete the cache of heavy games after completing levels if they take up too much space.
- 📱 Check the media auto-loading settings in instant messengers to stop the accumulation of garbage.
- 🚀 Clear browser data, including history and cookies, to speed up web surfing.
☑️ Weekly tablet hygiene
Deleting unnecessary files through the file manager
Standard Explorer Files or any other file manager allows you to see the structure of the storage with your own eyes. Often, users forget about downloaded installation files .apk, old documents or duplicate photos. Manually sorting folders is the most reliable way to free up space, since you personally control what is deleted.
Pay attention to the folder Download (Downloads). This is where most of the unnecessary digital junk accumulates. It is also worth checking the folders of specific applications, for example WhatsApp/Media or DCIM/.thumbnails. The folder .thumbnails contains thumbnails of images and can weigh unexpectedly a lot, taking up space even after deleting the original photos.
⚠️ Attention: When manually clearing system folders in the root of the internal memory, be extremely careful. Deleting files from directories with names like
Android/dataorsystemcan lead to incorrect operation of the operating system.
Do not forget about the recycle bin. In many modern file managers, deleted files do not disappear immediately, but are moved to the trash, where they are stored for 30 days. To actually free up space, you need to go to File Explorer settings and select the “Empty Trash” option. Only then will the disk space be available for writing new data.
Using an SD card to offload the system
If your tablet Lenovo supports memory cards, this is a great way to transfer heavy content from internal memory. Internal storage is faster but limited, whereas an SD card can hold hundreds of gigabytes of data. Transferring photos, videos and music to external media instantly makes the system work easier.
In the storage settings, you can change the default recording path. Go to Settings → Storage and select the memory card as the main location for saving new files. Also, many applications allow you to specify the path to save downloads in their settings. This will prevent the system partition from becoming clogged in the future.
How to transfer applications to an SD card?
In new versions of Android, this feature is limited to application developers. However, you can try going to Settings → Applications, select the application you want and click “Change” in the Storage section. If the button is active, select SD card. If not, the application does not support transfer.
It is worth noting that the speed of applications installed on a memory card may be lower than when installed in internal memory. Therefore, it is better to upload media files and documents to a flash drive, and leave critical apps on the system drive.
| Data type | Recommended storage location | Impact on speed |
|---|---|---|
| System applications | Internal memory | High speed |
| Photo and Video | SD card | Does not affect the system |
| Game cache | Internal memory | Fast loading of levels |
| Music and books | SD card | Comfortable playback |
Uninstalling the system Software (Bloatware)
Tablets Lenovo, like many other devices, often come with pre-installed software that is rarely used. This is the so-called bloatware: trial versions of antiviruses, games, partner applications. They not only take up space, but can also work in the background, consuming RAM.
It is not always possible to delete such applications in the standard way, since the “Delete” button may be inactive. In this case, you can try disabling the application in the settings. Go to the list of applications, select the one you don't need and click "Disable". This will hide the icon and stop processes, although the file will remain on the disk.
For advanced users, it is possible to remove system software via a computer using ADB-command. This requires enabling USB debugging in the Developer Options menu. The uninstall command is as follows:
adb shell pm uninstall -k --user 0 application package nameUsing this method requires precision. A misspelled package name or the removal of a critical system component can cause your tablet to become unbootable. Before such manipulations, be sure to create a backup copy of important data.
⚠️ Attention: Android shell interfaces are constantly updated. Menu items and settings names on your tablet may differ slightly from those described in the instructions. Always check the current manuals for your firmware version.
Radical method: Reset to factory settings
If none of the above methods helped and the tablet continues to slow down, the last option remains - a full reset. This procedure will return the device to the state it was in when purchased. Factory Reset Deletes absolutely all user data, applications and settings, leaving only a clean operating system.
Before starting the procedure, it is critical to save all contacts, photos and documents to external media or cloud storage. The process is irreversible: it will be impossible to recover deleted files after a reset without special, expensive equipment. Make sure that the battery level is at least 50-60% so that the device does not turn off during the process.
To start the reset, go to Settings → Recovery and reset → Reset settings. Confirm the action by entering your password or pattern, if installed. After rebooting, the tablet will begin a long procedure for cleaning and installing the system, which can take from 10 to 30 minutes.
A full reset is the most effective way to deal with software errors and accumulated system garbage that cannot be removed manually.
Preventing system contamination
In order not to return to the issue of cleaning every month, it is worth introducing several habits of using the tablet. Regular hygiene of your digital space takes less time than dealing with the consequences of memory clogging. Simple rules will help you maintain high performance Lenovo for years.
First, do not install applications from unverified sources. Third-party APK files often contain not only viruses, but also hidden miners or adware that clog up your memory with garbage. Secondly, use cloud services to store photo archives, freeing up local space.
- 🛡️ Install a reliable antivirus to prevent adware infections.
- ☁️ Set up automatic photo synchronization with Google Photos or Yandex.Disk.
- 🔄 Regularly reboot your tablet at least once a week to reset processes.
Following these recommendations will allow your tablet to remain fast and responsive. Remember that physical memory wear also occurs, so even ideal software cleaning will not restore the speed of a completely old device, but will significantly improve the situation.
Frequently asked questions (FAQ)
Is it safe to use cleaning applications like Clean Master?
Most modern security experts do not recommend using aggressive cleaners. They often contain advertising themselves, run in the background and consume resources that they supposedly save. The built-in Android tools are quite sufficient for normal operation.
Why does the memory quickly fill up again after cleaning?
This is normal system behavior. Applications constantly create new temporary files for their work. Also check if automatic downloading of attachments in instant messengers or synchronization of large amounts of data is enabled.
Is it possible to delete the Android folder on the tablet?
Absolutely not. This folder stores the data of all installed applications and the system cache. Removing it will cause apps to stop launching, and the system may display a critical error.
How to clear the cache of all applications at once?
There is no “Clear all” button in the standard Android menu. However, in the “For Developers” menu there is an option “Keep no activity”, but it does not clear the cache, but kills processes. It is better to do bulk cleaning through the engineering menu (code ##4636##), if it is available on your model, or manually.
Does full memory affect Internet speed?
Directly - no, but indirectly - yes. If the memory is full, the system has no place to create temporary files to buffer web pages and videos, which can lead to browser freezes and a feeling of slow Internet.
