Unfortunately, Rockstar Games doesn't provide a direct download link for GTA SA on their official website. However, they do offer the game on the Google Play Store.

You can download GTA SA from the Google Play Store using this link: https://play.google.com/store/apps/details?id=com.rockstargames.gtasa

I found that some users have reported issues with version 5.1, which might be related to performance or compatibility problems. If you're experiencing issues, you can try checking for updates or searching for alternative versions.

If you're experiencing performance issues or crashes, try adjusting the game settings, updating your graphics drivers, or freeing up storage space.

Enjoy playing GTA SA on your Android device!
