Owners of DEXP TVs running the Android operating system are often faced with the need to fine-tune the device for comfortable use. Launch applications may be accompanied by delays, and the operation of the interface may be slow, especially if the TV model was released several years ago. This is due to the fact that built-in hardware resources are limited, and modern versions of apps require more and more RAM.
When you turn on the TV for the first time or try to install new software from the Google Play store, the system can behave unpredictably. Optimizing the application becomes a critical stage, without which it is impossible to achieve smooth operation of the multimedia center. Users often wonder why the installation process takes so long or why the app crashes immediately after opening. In this article, we will analyze in detail the algorithms for correcting these problems.
Ignoring the procedures for clearing the cache and managing startup results in the set-top box turning into a slow device. It is necessary to understand the architecture of work Android TVin order to correctly distribute resources between background processes and active tasks. The correct approach to setting will extend the life of your comfortable operation DEXP TV without the need to immediately purchase new equipment.
Primary setup and diagnostics of the system
Before installing heavy applications or changing system parameters, it is necessary to conduct basic diagnostics of the current state of the operating system. Often the problem lies not in a specific application, but in general network or date settings. Make sure that the menu Settings → System → Date and time is set to the correct time zone and network synchronization is enabled. The wrong time can block the operation of Google services, which prevents normal Android launchservices.
The next step is to check the available space in the internal memory. DEXP TVs often have modest built-in storage that quickly fills up with system files and cache. If the free space is less than 500 MB, the system will begin to forcefully slow down any processes. It is recommended to go to the section Settings → Storage and assess how full the disk is.
⚠️ Attention: Do not try to fill the internal memory of the TV with media files. The built-in storage is intended solely for installing applications and storing their temporary data. For movies and music, use external USB drives.
It is also worth checking the firmware version. Manufacturers periodically release updates that contain compatibility bug fixes and optimizations for working with specific processor models. Go to Settings → About TV → System update and initiate a search for a new software version. If an update is available, installing it can solve the problem with the interface freezing.
Before starting any manipulations with the settings, write down the current brightness and color values on a piece of paper or take a photo of the screen. After resetting or updating, the parameters may return to factory settings.
The process of installing and initially launching applications
Installing applications on DEXP TVs has its own characteristics compared to smartphones. When you click the Install button on Google Play Store, the process of downloading the APK file and then extracting it begins. At this point, the message “Optimizing the application” may appear on the screen, which sometimes freezes in one place for several minutes. This is normal behavior for devices with slow eMMC drives.
It is important to understand the difference between installation and optimization. Installation is copying files, and optimization is compiling code for the specific processor architecture of your TV (usually ARM). If this process is interrupted, for example by unplugging the TV, the application may become inoperable or corrupted. In this case, a complete reinstallation will be required.
To speed up the process, it is recommended to close all background applications before installing new software. Press the Home button on your remote, highlight a running application, press the menu button (three dots or gear) and select Close. Freeing up RAM will give the system more resources to complete the task code compilation.
☑️ Checklist before installing the application
If the application is downloaded but not installed, check permission to install from unknown sources if you are using third-party files. To do this, go to Settings → Security and restrictions → Unknown sources and activate the switch for your file manager or browser. Without this step, the system will block the installation of any file not obtained through the official store.
Cache clearing and memory management
The accumulation of temporary files is one of the main reasons why a DEXP TV starts running slowly over time. The application cache speeds up their re-launch, but when it grows excessively, it begins to take up valuable space and conflict with new data. Regularly clearing the cache is a must to maintain high performance.
Cleaning can be done for each application separately or globally. For individual cleaning, go to Settings → Applications → All applications, select the desired app (for example, YouTube or Kinopoisk) and click “Clear cache”. Do not confuse this button with the “Clear data” button, since the second one will delete all your logins, passwords and settings inside the application.
| Clearing type | What is being deleted | Impact on account | Recommended frequency |
|---|---|---|---|
| Cache clearing | Temporary files, thumbnails | No impact | Once every 2 weeks |
| Cleaning data | Settings, logins, saves | Re-login required | Only in case of failures |
| Removing updates | Application version to factory version | Reset application settings | In case of critical errors |
For global cleaning, you can use built-in utilities or third-party launchers that have the “Accelerator” function. However, you should be careful with aggressive “cleaners” that can kill important system processes necessary for Android TV to work. It is better to limit yourself to manually clearing the heaviest applications, such as browsers and video services.
Configuring developer options for acceleration
For advanced users who want to squeeze maximum performance out of their DEXP TV, there is a “For Developers” menu. By default it is hidden. To activate it, you need to go to Settings → About TV and quickly click 7 times on the “Build number” item. After this, a new section will appear in the main settings menu.
In this section you can find parameters that affect the response speed of the interface. Find the items “Window Animation”, “Transition Animation” and “Animation Duration”. Change their value from standard 1x to 0.5x or disable them completely (Disabled). This will visually speed up the menu, since the TV will spend less resources on rendering graphic effects.
⚠️ Attention: Changing the background process limit in the developer menu may cause applications to be unloaded from memory too quickly. This will force the system to constantly restart them, which will ultimately increase the load on the processor and slow down the work.
You can also force GPU rendering in the developers menu. Find the option “Disable HW overlay” or “Hardware overlay” and activate it. This will shift some of the tasks of rendering the interface from the processor to the graphics core, which can have a positive effect on the smoothness of the image in heavy applications.
Hidden USB debugging capabilities
You can enable “USB Debugging” in the developers menu. This will allow you to connect the TV to your computer and control it via the ADB console, removing system junk that cannot be removed through the regular interface. However, this requires a PC and special knowledge.
Solving problems with freezing and crashes
The situation when an application starts, displays the splash screen and then crashes to the main screen is called a “crash”. This often happens with heavy games or unoptimized versions of video players on DEXP TVs. The main reason is a lack of RAM or incompatibility of the Android version with the app requirements.
The first action in case of frequent crashes should be to reset the settings of a specific application, as described in the section on cleaning. If this doesn't help, try uninstalling and installing an older version of the application. New versions of software often require more resources that the old TV hardware cannot provide. You can search for APK files of previous versions through the browser on the TV or PC itself.
Another common problem is processor overheating. If the TV is running for several hours in a row, especially in 4K resolution, the system may begin to throttle (reduce the frequency) of the processor, which leads to lags and app crashes. Allow the device to cool by unplugging it for 15-20 minutes. Make sure that the ventilation holes are not blocked by furniture or dust.
If the application crashes immediately after updating, the problem is most likely with the new software version. Rolling back to a previous version or waiting for a patch from the developer are the only working solutions in this case.
Using external memory and transferring data
Many DEXP TV models support the App2SD function, which allows you to transfer some application data to a connected USB drive. This is critical for models with a small amount of internal memory (4 GB or less). Connect a flash drive or external hard drive to the USB 3.0 port (usually blue) for maximum reading speed.
After connecting the drive, go to Settings → Storage. The system will prompt you to format the disk. Select the "Use as internal storage" option (if available) or simply allow applications to be installed on this drive. Please note that when formatting for internal memory, all data on the flash drive will be deleted, and it will be encrypted to work only with this TV.
Not all applications can be transferred to external media. System services and some critical components should remain in internal memory to ensure stability Android startup. However, transferring cache and large game files or media players can free up up to 70% of the internal space.
⚠️ Attention: The speed of applications located on a USB drive directly depends on the speed of the flash drive itself. Use USB 3.0 or higher standard drives. Cheap flash drives with low write speeds can cause even greater slowdowns than full internal memory.
Frequently asked questions (FAQ)
Why does the DEXP TV write “Not enough memory” even after deleting applications?
The Android system reserves part of the memory for system needs and cache. In addition, the deleted application may leave behind folders with data. It is recommended to use the “Clear cache” function for all remaining apps and restart the TV to update the free memory index.
Is it possible to install applications that are not on Google Play on a DEXP TV?
Yes, it is possible. You will need to download the APK file of the desired app to your computer, transfer it to a flash drive, insert the flash drive into the TV and open the file through the built-in file manager. Don't forget to first allow installation from unknown sources in your security settings.
How can I find out what version of Android is installed on my TV?
Go to the menu Settings → About TV. This section will indicate the operating system version (for example, Android 9.0 or Android 11) and the firmware build number. This information is necessary when searching for compatible versions of applications.
The TV is stuck on the DEXP logo when turning on, what should I do?
Try to force a reboot by holding the power button on the TV body (not on the remote control) for 10-15 seconds. If this does not help, you may need to perform a factory reset via Recovery Mode, which will delete all installed applications and data.
Does Internet speed affect application optimization?
Internet speed only affects downloading files. The optimization (compilation) process occurs locally on the TV processor and does not depend on network speed. However, a slow Internet can lead to a connection timeout when checking the application license, which is mistakenly perceived as an optimization problem.
