You NEED drivers for switch emulation on android.

If you have no idea what the hell drivers are, here is a video explaining all of it:

Introduction to Qualcomm Adreno & Mesa Turnip Custom GPU Drivers | Where to Download?

The TL:DR for those who just really don't feel like watching the entire video is basically think of drivers as a compatibility layer. A lot of people new to switch emulation think that their phone can run switch games and its always because they are not using drivers, which leads to issues with graphics.

1 - Go over to the menu of whatever android switch emulation on android

Click on "Install GPU driver)

2 - Download the appropriate driver (usually the latest "Mesa turnip" driver) and add it.

The file usually comes as a ZIP file, you do NOT NEED to extract it. It is good to use/add as is!

Make sure the blue circle is on "Mesa turnip adreno driver"

3 - You're good to go!

You can find all drivers available to download here: GitHub - K11MCH1/AdrenoToolsDrivers: A repository for Skyline, Vita3K and Yuzu Android compatible Adreno drivers.

As I said, I would mostly recommend the latest Mesa turnip drivers as qualcomm ones tend to be buggy for me, but try what works best for you.
