[Shizuku Method] Step-by-Step 90 FPS + 120 FPS GFX Tutorial for Android

ByTech Pranthan

Are you getting the “Can’t Use This: Folder” error or storage permission issues while using the 90 FPS + 120 FPS GFX after updating to Android 14? Don’t worry—you’re not the only one.

Many users are facing this problem on Android 13 and 14 because of strict file access rules.

In this easy guide, you’ll learn how to fix these issues using the Shizuku App — a powerful tool that gives apps extra permissions without needing root access.

Let’s fix your GFX Tool problem step by step!

Why Android 13 and 14 Cause Storage Problems

In Android 13 and 14, Google added stronger privacy and storage rules. Now, apps can’t access certain folders especially game data folders without special access.

That’s why the GFX Tool often shows errors like “Can’t Use This Folder.” Even if you allow normal permissions it still can’t reach those folders. This affects apps that need to change game settings.

What is the Shizuku App?

Shizuku is a special Android tool that helps apps get system-level permissions without rooting your phone.

It uses something called Wireless Debugging to safely connect the app to your phone’s system. This allows apps like GFX Tool to work properly and change game settings, even with Android’s new restrictions.

How Shizuku Fixes the Storage Issue

When you use Shizuku, it lets GFX Tool directly access the Game data folder. Android’s security won’t block it because the tool gets special temporary permission using wireless debugging.

This helps GFX Tool work smoothly, without showing any “folder access” errors.
