Fortnite Graphics Glitches on Galaxy S24: How to Fix

Fortnite, a popular battle royale game, can sometimes experience graphics glitches and performance issues on the Samsung Galaxy S24 Ultra. To help you overcome these problems, we've compiled several step-by-step solutions to improve your gaming experience.

Adjusting Graphics Settings

Setting Graphics to Low Quality

Open Fortnite: Launch the Fortnite app on your Galaxy S24 Ultra.
Go to Settings: Navigate to the game settings by tapping the menu icon.
Select Graphics Quality: Find the graphics quality option and set it to "Low."
Set FPS to 30: Ensure the frame rate is set to 30 FPS for smoother gameplay.

This method can significantly reduce lag and improve overall performance, as demonstrated in a test where Fortnite ran smoothly on low graphics settings at 30 FPS.

Disabling Auto Blocker and Enabling Sideloading

Bypassing Samsung's Auto Blocker

Go to Settings: Open the Settings app on your Galaxy S24 Ultra.
Find Security Settings: Navigate to the "Biometrics and security" or "Security" section.
Disable Auto Blocker: Look for the Auto Blocker feature and disable it.
Enable Install from Unknown Sources: Allow installations from unknown sources to sideload apps if necessary.

Epic Games has removed Fortnite from the Galaxy Store due to Samsung's Auto Blocker, but disabling it can help in sideloading the game or using alternative app stores.

Optimizing Device Settings for Gaming

Changing Device Settings to Reduce Lag

Wipe Cache Partition: Go to the recovery mode and wipe the cache partition to clear temporary system files.
Update Game and Clear Cache: Ensure the game is updated and clear its cache by long-pressing the app icon, going to storage, and clearing the cache.
Turn Off Power and Data Saving Mode: Disable power-saving modes to prevent throttling of the device's performance.
Turn On Game Labs: Enable Game Labs in the game settings to access additional performance optimization options.
Turn Off Auto Manage Performance: Disable auto-managed performance to prevent the system from throttling the game's performance.
Enable Game Booster Plus: Activate Game Booster Plus to enhance gaming performance.
Set Priority Mode: Enable Priority Mode to allocate more resources to the game.
Adjust Graphics Driver: If possible, change the graphics driver to a more optimized version.

These steps can help in reducing lag and improving overall gaming performance on the Galaxy S24 Ultra.

Addressing Vulkan API Issues

Checking and Adjusting Vulkan API Usage

Check GPUWatch: Use the GPUWatch feature in developer settings to see if the Vulkan API is being used. If not, it might be using OpenGL, which could be less efficient.
Report Issues to Epic: If the Vulkan API is not being used, report the issue to Epic Games, as they may need to whitelist your device model to enable Vulkan API support.

Some users have reported performance issues after the Vulkan API was disabled in a recent update. Reporting this issue to Epic Games could help in resolving it.

Updating Software and Games

Keeping Software and Games Updated

Update Android and One UI: Ensure your device is running the latest version of Android and One UI, as updates often include performance improvements.
Update Fortnite: Keep the Fortnite app updated, as new updates may include fixes for performance issues.

Regular updates can resolve many issues related to game crashes and performance glitches, so it's crucial to keep both the operating system and the game updated.

Additional Troubleshooting

Checking for Specific Game Issues

Identify Game-Specific Problems: Some games may have unique issues. Identify which games are causing problems and check for specific solutions or updates related to those games.
Disable RAM Plus: If you have RAM Plus enabled, try disabling it, as some users have reported fewer crashes after doing so.

By troubleshooting specific game issues and adjusting settings accordingly, you can often resolve performance problems that are game-specific.
