Genshin Impact is one of the most popular open-world RPG games, but its installation on budget smartphones like Xiaomi Redmi 9C often raises questions. The point is not only in the weight of the game (about 15–18 GB after a full download), but also in the hardware limitations of the device: the processor Helio G35, 2-3 GB of RAM and Android 10/11 do not always guarantee smooth gameplay. However, with proper settings, the game runs even on such models - the main thing is to follow the proven steps.

In this guide we will analyze all current download methods (including the official website, Google Play and APK files), optimizing settings for Redmi 9C, as well as solutions to typical errors like "Insufficient memory" or "The device is not supported". Let us separately dwell on the nuances of working with MIUI —a proprietary shell Xiaomiwhich can block installation from unknown sources.

Method 1: Installation via Google Play (officially)

The simplest and safest method is to download the game via Google Play. However, there are pitfalls: the application may not show up in search due to regional restrictions or "incompatibility" with the device (even if it is technically suitable).

To get around this:

  1. Open Google Play and in the search bar type "Genshin Impact".
  2. If the game is not located, go to direct link (will open in the browser).
  3. Click "Install". If an error appears "Device not supported", use VPN (for example, ProtonVPN or Warp) with region USA or Japan.
  4. After successful installation, the VPN can be disabled.

If the game has downloaded, but does not start with an error "Insufficient memory", clear the cache Google Play Services:

  1. Go to Settings → Applications → Manage applications.
  2. Find Google Play Services, click "Storage" → "Clear cache".
  3. Restart your phone and try to launch the game again.

Method 2: Download from the official miHoYo website

If Google Play doesn't work, download the APK file directly from the developer's site. This is safe because the file is signed with an official digital signature miHoYo. Instructions:

  1. Open the browser and go to official website.
  2. In the top menu, select "Play" → "Android".
  3. Click "Download" — the file weighs ~150–180 MB (this is only the installer, the rest will be downloaded on the first launch).
  4. After downloading, open the file. If a warning appears "Installation blocked", allow installation from unknown sources:
    • Go to Settings → Applications → Special permissions → Install unknown applications.
    • Select a browser (for example, Chrome or Mi Browser) and enable the resolution.

Important: When you first launch the game, it will start downloading additional files (~15 GB). Use Wi-Fias mobile traffic can dry up quickly. If the download is interrupted, check the settings MIUI:

  • Open Settings → SIM cards and mobile networks → Data transfer.
  • Disable "Saving traffic" for Genshin Impact.
💡

If the game is slow on Redmi 9C, lower the graphic settings in the menu Settings → Graphics to 60 FPS i "Low" texture quality. This will reduce the load on the processor and RAM.

Method 3: Alternative sources (APK file)

If official methods do not work, you can download APK from trusted sites like APKMirror or TapTap. However, there are risks:

  • ⚠️ Viruses: Only trusted sources (avoid little-known sites).
  • ⚠️ Outdated versions: Check the APK update date.
  • ⚠️ Account blocking: miHoYo can ban an account for using modified files.

Safe instructions:

  1. Download APK from APKMirror (choose the latest version).
  2. Before installation, check the hash of the file (for example, via Hash Droid iz Google Play) - it must match what is specified on the site.
  3. Install the APK, allowing installation from unknown sources (as in Method 2).
  4. After launch, wait for the game to update via the built-in launcher.
⚠️ Attention: On Redmi 9C with 2 GB of RAM, alternative APKs may perform worse than the official ones due to the lack of optimization for weak devices. If the game crashes, try rolling back to version 2.8 or 3.0 —they are less demanding.

What to do if the game crashes when loading?

Check the free space on your device - if less than 5 GB, clear the cache or transfer the files to an SD card (if supported). Also try reinstalling the game by first deleting the folder com.miHoYo.GenshinImpact in Android/data (use a file manager with root access or MI File Manager).

Solving common errors on Redmi 9C

When installing or launching Genshin Impact on Redmi 9C users encounter several common problems. Let's look at them step by step:

Error Cause Solution

  • Delete unnecessary files or transfer them to an SD card.
  • Clear the cache via Settings → Storage.
"Device not supported" Google Play or website miHoYo detect Redmi 9C as incompatible. Use a VPN with a region US/Japan or download APK from APKMirror.
"Error downloading files" (code 9203/4201) Problems with the Internet connection or blocking MIUI.
  • Disable "Saving traffic" in the network settings.
  • Connect to another Wi-Fi network.

  2. Confirm the reset and reboot the phone.
  3. Run again Genshin Impact.
💡

On Redmi 9C with 2 GB of RAM, the game can only work with a complete memory clear and minimal graphic settings. If the lag persists, consider upgrading your device or using cloud gaming (for example Boosteroid).

Transferring Genshin Impact to an SD card (if supported)

Redmi 9C supports memory cards microSD up to 512 GB, but transferring the game to them has nuances. The fact is that Android by default it does not allow you to move OBB files (additional game data) to an external drive. However, there is a workaround:

  1. Insert the SD card into the phone and format it as "Internal memory" (all data on it will be deleted!):
    • Go to Settings → Storage → SD card.
    • Click "Format as internal".
  • After formatting, restart the phone.
  • Install Genshin Impact again - the system will automatically offer to save the data to the SD card.

    • Important: This method does not work on all firmware MIUI. If the option "Format as internal" is missing, use a file manager with rights root (for example, Root Explorer) to manually transfer the folder com.miHoYo.GenshinImpact to the SD card.

    ⚠️ Attention: If you remove the SD card, the game will stop working. Also, the loading speed of locations may decrease if the memory card is class UHS-I or slower.
