I just bought and installed the Minecraft application via Google Play Store. I attempted to run and play but the application won't load past the black-white loading screen (refer to the video attached). 

I have published a review on it. Seems like other users of Galaxy S21 Ultra encountered a similar problem. 

In an attempt to make it work (but still failing), I have tried the following methods: 

1. Clear data and cache of the application. 
2. Re-installing the application thrice. 
3. Restart the device. 
4. Soft-reset the device. 
5. Hard-reset the device. 
6. Uninstall other applications, leaving basic applications pre-installed on the device. 
7. Change between mobile data and wifi while downloading/installing/running the application.
