Supercell’s Brawl Stars has become one of the most popular mobile games due to its dynamic gameplay and graphics. However, many players on Xiaomi smartphones (including the Redmi, POCO and Mi lines) face a problem: the game does not occupy the entire screen, leaving black bars on the sides or on the top, not only spoils the visual experience, but also interferes with accurate control – especially in modes where every millisecond is important.
The reason lies in the features of the MIUI firmware and the aspect ratio of the screen. Modern Xiaomi smartphones often use displays with cutouts (“monobrov”) or rounded corners, and the game is optimized by default for the standard ratio of 16:9. As a result, the system automatically scales the image, leaving empty space. Fortunately, there are several ways to force fullscreen (forced full screen mode) – from the settings of the game itself to hidden MIUI functions.
In this article, we will discuss 5 proven methods to remove black stripes in Brawl Stars on Xiaomi, including models with a high-end design. AMOLED-You will also learn why some methods may not work on older versions of the game or firmware, and how to circumvent these limitations.
1. Enabling full screen mode in Brawl Stars settings
The easiest way is to use the game's built-in options.The developers of Supercell have added support for full-screen mode, but the feature can be hidden or disabled by default.
To activate it:
- 🎮 Launch Brawl Stars and wait for the main menu to load.
- ⚙️ Click on the gear icon (settings) in the upper right corner.
- 📱 Scroll down to the Screen or Display section (the title may vary depending on the game version).
- 🔄 Find the option Full Screen Mode and switch the switch to the position of the on.
- 🔄 If you don’t have an option, upgrade to the latest version on Google Play or AppGallery.
On some Xiaomi devices (e.g. Redmi Note 11 Pro+ or POCO F4), once this option is enabled, the game automatically adapts to the screen resolution, removing the black bars. However, if the image is stretched or distorted, move to the next method.
💡
If after the full-screen mode is turned on, artifacts appear in the game (blurred textures, cropped interface elements), try temporarily disabling hardware acceleration in the MIUI developer settings.
2.Scaling setup in MIUI for Brawl Stars
MIUI has hidden options that allow applications to be forcibly stretched to the full screen, and this method works even if the game does not officially support full screen mode.
Instructions:
- Open Settings → Applications → Application Management.
- Find the Brawl Stars list and tap it.
- Select Full Screen Mode (Full Screen Display)
- Activate the option to stretch to the full screen or Hide the cut (depending on the version of MIUI).
- Save the changes and restart the game.
On some models (such as Xiaomi 12T or Redmi K50), this item may be called Full-screen Display and be in the Additional section. If the option is not available, then your version of MIUI does not support forced scaling for games.
What if the "Full Screen Mode" option is inactive?
Important: Forced stretching can cause important interface elements (such as control buttons or health indicators) to be cropped. If the game becomes uncomfortable, return the settings.
3.Using the Developer Mode for Forced Fullscreen
If standard methods don’t work, you can use the developer mode in MIUI, which requires more action, but gives you better results on devices with non-standard aspect ratios (for example, 20:9 or 21:9).
Step-by-step:
- Activate Developer Mode: Go to Settings → About Phone. Tap 7 times on MIUI until you become a developer!

5. circumvention of restrictions through third-party launchers
If none of these things worked, you can use third-party launchers that force full-screen games to run, such as Nova Launcher or Hyperion Launcher, which have built-in options for scaling apps.
How it works:
- 📥 Install Nova Launcher from Google Play.
- 🔧 Open the launcher settings and go to Apps and widgets → Application settings.
- 🎯 Find Brawl Stars in the list and activate Full Screen Mode or Ignore Notches.
- 🔄 Save the changes and launch the game through the launcher.
The advantage of this method is that it does not require root rights and works on most versions of MIUI, including MIUI 14. However, some launchers may conflict with system animations, so check the stability of the phone after setting up.
💡
The launcher side is a versatile solution for devices that lock the system settings of full-screen mode, but they can slightly increase battery consumption due to background work.
Solving the Problem: Why Full Screen Mode Doesn't Work
Even after all these methods have been applied, some users are faced with the fact that the black bars remain, and let's look at the main reasons and ways to eliminate them.
| Problem. | Possible cause | Decision |
|---|---|---|
| Full-screen mode option in the game is inactive | Brawl Stars or MIUI version | Update the game in the store and check for firmware updates in Settings → System Update |
| Image stretched with distortion | Incorrect aspect ratio in MIUI settings | Return standard resolution or disable forced scaling |
| The game will fly out when full screen mode is turned on | Conflict with optimizing MIUI for gaming | Turn off Game Mode in Settings → Special Opportunities → Game Turbo |
| The black stripes remain only in battle. | Limitation of the server part of the game | Try changing the server in the Brawl Stars settings (if available) |
If none of these methods worked, the problem may lie in the hardware limitations of your device, for example, on some budget Redmi models (for example, Redmi 9A or Redmi 8), full-screen mode in games is blocked at the firmware level due to a weak processor.
💡
Before experimenting with settings, back up your game data through Settings → Apps → Brawl Stars → Backup. This will help restore progress if something goes wrong.
