Your Xiaomi Mi TV or Redmi Smart TV suddenly becomes slow to respond to remote commands, hangs over when switching channels, or “thinks” when launching applications? This is a common problem that smart TV owners face after 1-2 years of use. The reasons can be rooted in software failures and hardware limitations. In this article, we will analyze all possible causes of brakes and give step-by-step instructions for eliminating them, from basic actions to advanced methods for experienced users.
It's important to understand that brakes don't always mean that you're going to break, and most often you're going to be stuck in a cache, in the background, in outdated software, or incorrect settings, and less often you're going to be dealing with hardware problems like flash wear and tear or overheating, and we've structured solutions by complexity: start with simple steps and only go to radical measures if the previous ones haven't worked.
Modern Xiaomi TVs are based on Android TV or proprietary PatchWall shell (in models for India), which imposes its own features on diagnostics. For example, in Mi TV 4S or Redmi X50, it is PatchWall interface that often slows down, whereas in global versions the problems are associated with Google Play Services.
1.Rebooting the TV is the first step
It sounds trite, but software reboot solves up to 30% of the time brakes. Unlike smartphones, Xiaomi TVs rarely reboot automatically, and background processes (such as weather updates or account sync) can accumulate for days.
How to properly reboot:
- 🔄 Soft reboot: Press the Power button on the remote for 5-7 seconds until the menu appears, then select Reboot».
- 🔌 Hard reset: If the TV doesn't respond, pull the power cord out of the socket for 1-2 minutes (at least 60 seconds!) This will reset RAM and core cache.
- ⚡ Reset via service menu: For Mi models TV 4A/4C Press sequentially: Menu → Settings → All settings → On TV. → Reboot.
After restarting, check the speed for 10-15 minutes. If the brakes are gone, the problem was a temporary failure of RAM. If not, move on to the next step.
2. Cleaning the cache and application data
The main reason for the brakes is a crowded cache of system and user applications. In Android TV, the cache does not clear automatically, but takes up to 2-3 GB of memory, especially for models with 8 GB of internal memory (for example, Mi TV 4A 32).
Cleaning instructions:
- Go to Settings → Applications → Installed Applications.
- Select the app (start with Google Play Services, PatchWall, YouTube).
- Click on “Clear Cache” then “Clear Data” (Warning: This will reset the app settings!).
- Repeat for all applications that take up more than 100MB.
To speed up the process, use the service menu of the engineering mode:
Settings → About TV → Press 5 times in a row on “Model TV” → Select “System Cleanup”Clear the cache of Google Play Services
Delete the data of PatchWall Launcher
Check the free space in the Settings → Storage
Reboot the TV after cleaning-->
Critical information: On Xiaomi TV A2 models and later, cleaning the cache through the engineering menu can lead to a Wi-Fi network reset.
Update of firmware and software
Outdated firmware is the second most common cause of brakes. Xiaomi regularly releases updates to optimize performance, but auto-update may be disabled.
- Go to Settings → About TV → System Update.
- Compare your version with the latest on the official website.
If the update is available:
- 🌐 Online: Select “Update Now” (requires a stable connection!).
- 💾 Through USB: Download the firmware for your model with Xiaomi Firmware. unpack ZIP-file and copy the file update.zip flash-drive (FAT32!). Insert the flash drive in the TV, go to Settings → Update → Update through USB.
