Owners of Xiaomi Redmi 9S smartphones often face an unpleasant surprise when trying to install the popular game Genshin Impact. Despite the fact that the device is equipped with a Snapdragon 720G processor and 6 GB of RAM, official app stores can issue a message about incompatibility. This is due not only to hardware, but also to the software restrictions that the developer HoYoverse imposes on certain versions of the operating system and screen configurations.
Making matters worse, the game is constantly overgrown with new content, raising minimum requirements for GPU and free memory. APK-file from an unverified source, risking crashes during the resource loading phase or black screen.Critical factor for Redmi 9S lack of support for some advanced graphics drivers in stock firmware MIUI, What blocks the Unity engine from running in the required mode.
In this article, we will discuss why your phone doesn’t formally support the game, and what are the real ways to run the project on the device.We will look at methods to modify system files, use cloud services, and configure emulation so that you can get into the world of Teivat even on an “unsupported” gadget.
Technical reasons for blocking the installation on Redmi 9S
The first thing to understand is the nature of the restriction. When Google Play writes “Device not supported,” it often means that the game developer blacklisted your device. For Redmi 9S, the main problem is unlocking Bootloader and having Root rights, which the game’s security system considers a threat to data integrity.
There's also a problem with the processor architecture. 720G architecture-based ARM64, Some game libraries require specific instructions that may not be implemented correctly in drivers. MIUI 11 or 12 pre-installed in the factory, which means that even if you have a successful installation, APK-file, the application is closed immediately after the logo appears.
The temperature is also important. Genshin Impact puts extreme strain on the processor. In Redmi 9S, the cooling system is not designed to last long at the limit, so the software limiter can block the launch of heavy applications to prevent overheating and failure of the motherboard.
- 📱 The discrepancy of the minimum version of Android in the requirements of the updated client of the game.
- 🛡️ Activated Developer Mode or Debugging USB, anticheat-detectable.
- 💾 Insufficient continuous space for unpacking resources (more than 30 GB required).
⚠️ Note: Attempting to circumvent file integrity checks may result in account blocking by game developers. Use only legal methods of modifying the client part, not affecting the network code.
It's important to distinguish between store-side software lock and physical inability to run. In the case of the Redmi 9S, we're dealing with a hybrid problem: the device is powerful enough, but the software crutches of the manufacturer and the developer create an artificial barrier, and understanding this difference is essential to choosing the right solution.
Preparation of the device for installing game files
Before you start manipulating installation files, you need to properly prepare the environment. On a Xiaomi smartphone, it starts with cleaning up the space. The game takes up a huge amount of space, and if less than 5 GB is left on the disk freely, the unpacking process will interrupt, damaging the files.
The second step is to configure the installation sources, and you need to allow the installation of applications from unknown sources. → Device protection → Confidentiality → Special facilities → Install unknown applications. You need to give permission to your file manager and browser.
It is also recommended to disable MIUI optimization for a particular application if it is already installed but is not working. Go to Settings → Apps → All Apps → Genshin Impact (if any) and find the item “Other permissions”. Here you can try to remove the restrictions of background activity, although this is not always critical for the initial launch.
☑️ Redmi Preparation 9S installation
Don’t forget to check the MIUI version. If you have a global firmware installed based on Android 10, you may not have some of the libraries that Android 11 or 12 has. Consider upgrading your system through the About Phone menu → MIUI version if newer versions of the software are available.
Methods of bypassing compatibility checks via APK
The most common way is to install a modified installer. The official APK from the site often contains a signature check of the device. Enthusiasts create patched versions of the installer that disguise the Redmi 9S as older or supported models, such as the Redmi Note 9 Pro.
To implement this method, you will need to download the Genshin Impact Universal Installer. Once you run the installer, it will not check the device model as strictly as Google Play. However, the game client itself may still require you to download additional resources that may not be installed on the disk.
There is also a method of editing a build.prop file, but it requires Root rights, which is highly discouraged for ordinary users because of the risk of turning the phone into a brick.A safer option is using environment cloners such as VirtualXposed or Gspace, which create virtual space with different device parameters.
| Method | Difficulty | Risk of bana | Stability |
|---|---|---|---|
| Official APK from the site | Low. | No. | Low (departures) |
| Patch installer | Medium | Medium. | Medium |
| Virtual Environment (Gspace) | Low. | Low. | Tall. |
| Editing by build.prop | Tall. | High-pitched | Unstable. |
When using third-party installers, always check the hash amount of the file. downloading modified customers from questionable resources can lead to theft of your account data. Use only verified modder communities.

Using Cloud Gaming as an Alternative
If local launch is impossible or causes a lot of heat, the ideal solution for the Redmi 9S is cloud gaming, in which case the game runs on a powerful server, and your phone is transcribed video stream, which takes the load from the Snapdragon 720G processor and allows you to play even at maximum graphics settings.
GeForce NOW or specialized Asian services that support Genshin Impact are popular. For Russia and the CIS, services such as MFog or Cloud Gaming from various providers are relevant. The main requirement here is a stable Internet with a speed of at least 15-20 Mbit / s.
The advantage of this method is that you don't have to download 30+GB of data, you just install a lightweight application client of the service, log in and start the game, and it also solves the problem of lack of internal memory, which is often critical for the Redmi 9S with a base storage capacity of 64GB.
- ☁️ No heating of the device during the game.
- ⚡ Instant launch without long screen loads.
- 📉 Saving battery power, as it works only as a decoder.
⚠️ Attention: For comfortable play in the cloud requires a 5 GHz Wi-Fi connection. 4G This can lead to dissynchronization of the image and control, which will make the game impossible.
Keep in mind that cloud services are usually paid or have free time limits, but for a device that doesn’t natively support the game, this is often the only way to get a full experience without lags and departures.
💡
Use an Ethernet adapter via USB-C to connect the Redmi 9S to the router with a cable, which will provide minimal ping and connection stability, which is critical for cloud gaming.
Optimizing the system to improve productivity
If you want to play the game locally through APK, You need to get the most out of the system. MIUI There's a hidden developer menu that lets you turn off unnecessary animations and free up resources. → The phone. → 7 times press on "Version" MIUI", Then in the advanced settings, find the section "For developers».
It is important to find the “Funded Processes” item and limit the number of them, and it is also worth disabling “MIUI Optimization” if this option is available after unlocking the bootloader (although this may disrupt some system functions), a safer way is to use the Game Turbo application built into the shell.
In Game Turbo settings, add Genshin Impact manually if it's not there. Select a Balanced or Performance profile, but keep an eye on the temperature. Network Acceleration can help stabilize the ping, redistributing traffic in favor of the game.
Another important aspect is memory management. Close all background apps before you launch. The 4GB RAM Redmi 9S will be extremely difficult to keep the game in the background, so any free megabyte is important. You can use ADB commands to force clear the cache before you launch.
adb shell pm trim-caches 999999999This command, executed via a computer with a USB phone connected, will clear the cache of all applications, freeing up valuable space, which is especially useful if the game crashes when you load resources with a message about a memory shortage.
💡
The combination of Game Turbo, cache clearing and background closure can boost FPS by 5-10 frames, which is critical for playability on the Redmi 9S.
Possible errors and ways to eliminate them
Even after all the manipulations, you may encounter errors, the most common being "Error Code 4206" or endless resource downloads, which means that the anti-cheat can't verify file integrity, in which case cleaning the application data through the application management menu and re-loading resources only through Wi-Fi will help.
If the game is running but it's 1-2 frames per second, it means that the high-resolution rendering is enabled. In the settings of the game itself (if you get into the menu), reduce the rendering resolution to 0.6 or 0.8. This will greatly degrade the picture, but will increase the responsiveness of the control.
The "Not enough space" error, although there is space, is often associated with the file system.Redmi 9S uses a file system that can fragment.It is recommended to make a full backup and format internal storage to create continuous space for game files.
- 🔄 Resetting network settings can help if the error is related to connecting to download servers.
- 📂 Delay the game SD-The card is not recommended due to the low reading speed, which will cause constant loading of textures.
- 🔋 Power saving is mandatory, otherwise the system will trott the processor to a minimum.
If you have a black screen with sound, try changing the screen resolution in the engineering menu (access to the Xiaomi engineering menu, code ##6484##), but this is an advanced level, and changing the native resolution can lead to the system interface inoperability.
