1. Clearing cache and temporary files

The most common cause of slowdowns is clogged cache applications and the system. Over time, temporary files accumulate and take up precious space, slowing down your work. On Android TV you can clear the cache in two ways: manually for each application or globally for the entire system.

To clear the cache of an individual application (for example, YouTube or Netflix):

  • 📺 Go in Settings → Applications.
  • 🔍 Select the desired application (for example, Google Play Store).
  • 🧹 Press Clear cache (do not confuse with Clear data —this will delete all settings!).
  • 🔄 Reboot the TV via Settings → Device → Reboot.

For global cleaning (if the entire system is slow):

  • 🛠️ Open Settings → Memory and storage → Internal memory.
  • 🗑️ Select Cached data and confirm clearing.
  • ⚠️ Attention: After this operation, some applications (for example Kodi or IPTV players) may require repeated authorization.

☑️ What to clear first

Done: 0 / 4

If after clearing the cache the brakes remain, check the free space on the device. For stable operation Android TV minimum is required 500 MB of free spaceIf there is less memory - delete unnecessary applications or transfer media files to an external drive.

2. Disabling autorun and background processes

Many applications on Smart TV start automatically when you turn on the TV and run in the background, consuming resources. streaming services (Netflix, OKKO), but also system utilities (Google Play Services, Android Accessibility Suite).

To disable autorun:

  1. Hold the button Home on the remote control and hold for 5 seconds to open the menu Android TV.
  2. Go to Settings → Applications → Accessibility → Autorun.
  3. Disable autorun for all applications except critical ones (for example, Google Play Market and System updates).

To disable background processes:

  • 🔧 In the menu Settings → Applications select the application (for example, Facebook Watch).
  • 🚫 Click Stop (if the button is active) and disable the option Allow background activity.
💡

If there are unknown apps with Chinese names in the application list (for example, com.duokan.phone.remotecontroller), you can safely disable them - this is pre-installed software from the manufacturer, which is rarely used.

After these manipulations, the TV will start faster and the interface will become more responsive. However, be careful: disabling system processes (for example, Android System Intelligence) may lead to malfunctions of the voice assistant or recommendations. content.

3. Firmware and software update

Outdated firmware is one of the main reasons for slowdowns. Manufacturers regularly release updates that optimize the system, correct errors and add support for new codecs (for example, AV1 For YouTube v). 4K).

To update the software:

  • 📡 Go to Settings → Device → Software update.
  • 🔄 Click Check updates.
  • 📥 If an update is found, confirm the installation and wait for the reboot (this may take 10-20 minutes).

If automatic updating does not work:

  • 🌐 Connect the TV to the Internet via cable (Ethernet), since the wireless connection (Wi-Fi) may be interrupted.
  • 🔌 Make sure that the TV is connected to an uninterruptible power source (some models turn off updates at low voltage).
  • 📁 Download the firmware manually from the manufacturer’s official website and install it via Settings → Software update → Local update.
What to do if the update is stuck?

If the update process is interrupted or frozen during the installation stage, do not turn off the TV! Wait 30 minutes - sometimes the system recovers on its own. If the screen remains black, turn it off. power for 1 minute, then turn on the TV and repeat the update.

After updating, reset the settings Google Play Store:

  1. Open Settings → Applications → Google Play Market.
  2. Click Storage → Clear data.
  3. Reboot the TV.

This will help avoid errors when installing new applications.

4. Optimizing display and animation settings

Visual effects and interface animations Android TV look beautiful, but consume resources. By disabling them, you can significantly speed up the system, especially on weaker models (for example, Xiaomi Mi TV 4A or Philips 32PFS5805).

To speed up the animation:

  • 🎨 Go to Settings → Device → Developer options.
  • 🔍 If the item is not there, activate it: open Settings → About TV and click on Build number.
  • ⚡ In the developer menu, find the options:
    • Window animation scale → No animation
    • Transition animation scale → No animation
    • Animation duration → Off

Also recommended:

  • 🖼️ Set static wallpaper instead of live ones (in Settings → Screen and sound → Wallpaper).
  • 📊 Disable adaptive brightness (in Settings → Screen and sound → Brightness), since the light sensor constantly polls the system.
  • 🔊 Reduce the number of recommendations displayed on the main screen (in Settings → Home screen → Customize rows).

On TVs Sony Bravia 2020–2023 disable animation gives a speed increase of up to 30% when navigating through the menu.

5. Using an external drive (USB/SSD)

If the built-in memory is not enough and you don’t want to delete applications, you can transfer some of the data to external drive a flash drive (USB 3.0) or SSD. This is especially true for TVs with 8–16 GB of internal memory (for example, TCL 40S5200 or Hisense 43A6K).

How to set up an external drive:

  1. 🔌 Connect USB flash drive (recommended USB 3.0 with a capacity of 32 GB or more) or SSD to the TV port.
  2. 📁 Go to Settings → Memory and storage → External devices.
  3. 🔄 Format drive as Internal memory (all data will be deleted!).
  4. 📱 After formatting, the option will appear in the application settings Transfer to SD card.

Advantages and disadvantages of external drives:

Drive type Operating speed Compatibility Price (for 64 GB)
USB 2.0 flash drive Low (up to 30 MB/s) All models from 500 ₽
USB 3.0 flash drive Medium (up to 100 MB/s) TV with port USB 3.0 (blue connector) from 1,000 ₽
External SSD High (up to 500 MB/s) TV with USB 3.0/3.1 and external power supply from 2,500 ₽

⚠️ Attention: some TVs (for example, LG on webOS) do not support formatting external drives as internal memory. In this case, you can use the flash drive only to store media files, but not to install applications.

6. Reset to factory settings

If all the previous methods did not help, all that remains is last resort resetting the TV to factory settings. This will remove all installed applications, accounts and settings, but will return the system to its original speed. It is recommended to reset every 1-2 years.

How to reset settings:

  1. 🔒 Go to Settings → Device → Reset.
  2. 🗝️ Select Erase all data (factory reset).
  3. 🔄 Confirm the action and wait for the reboot (takes 5-10 minutes).

After reset:

  • 📋 Do not restore data from a backup - this may return old errors.
  • 🆕 Install only necessary applications (for example, YouTube, Netflix, IPTV).
  • 🔐 Do not register unnecessary accounts (for example, Facebook or Twitter), unless use them.
💡

Resetting to factory settings is the most effective way to speed up an old TV, but you should only use it after backing up important data (for example, saved games or settings Kodi).

⚠️ Attention: on some models (Samsung on Tizen or LG on webOS), a reset may block access to some functions (for example, Ambient Mode or Game Mode). Before resetting, check whether your TV supports restoring these functions after authorization in the manufacturer's account.

7. Alternative launchers and firmware

The standard launcher Android TV is often overloaded with unnecessary widgets and advertising. By installing alternative launcher, you can speed up navigation and simplify the interface. Popular options:

  • 🚀 ATV Launcher - minimalistic launcher with quick access to applications.
  • 🎮 Wolf Launcher - optimized for gamers (support Stadia i GeForce NOW).
  • 📺 Hal Launcher - imitates the interface Apple TV with smooth animations.

To install an alternative launcher:

  1. Download APKlauncher file to a flash drive (for example, from the site APKMirror).
  2. Connect the flash drive to the TV and open File Manager (or ES Explorer).
  3. Install APKby allowing installation from unknown sources (Settings → Security → Unknown sources).
  4. Hold the button Home on the remote control and select the new launcher as the main one.

For advanced users there is an installation option custom firmware (for example, LineageOS for TV). This gives complete control over the system, but requires unlocking the bootloader and may void the warranty. Read more about firmware for specific models on the forums 4PDA or XDA Developers.

8. Optimizing the network and connections

Slow Internet or an unstable connection can create the illusion of slowness, especially when watching 4Kvideos or online games By optimizing the network, you will eliminate delays and jerks.

How to speed up the Internet on Smart TV:

  • 🌐 Connect the TV to the router via cable (Ethernet) instead of Wi-Fi - this will reduce the ping and eliminate packet loss.
  • 📶 If Wi-Fi is unavoidable, use band 5 GHz (in the router settings) - it is less loaded than 2.4 GHz.
  • 🔄 In the TV menu (Settings → Network and Internet → Wi-Fi) disable option Automatic connection to open networks.
  • 🛡️ Configure QoS on the router to prioritize TV traffic (especially for Netflix or YouTube).

If network problems persist:

  • 🔌 Restart the router and TV.
  • 📡 Check if other devices (microwaves, cordless phones) are interfering with the frequency 2.4 GHz.
  • 🔧 Update the router firmware (via the web interface, usually 192.168.1.1).
💡

If you have Xiaomi Mi TV, there is a hidden option in the network settings Game traffic mode (Settings → Accessibility → Network). in online games for 20–40 ms.
