Hola Friends,
I'll guide you through the installation of Google Assistant to any Android Device running Android N 7.0/7.1
Remember: I'm not responsible for anything goes wrong during the process.
Let's begin,
1. Download Get Assistant from Play Store
2. Install it.
3. Give Root access to the application.
4. Click on Get Assistant.
5. You're Done.
6. Restart the device
7. Long press the Home Button and setup Google Assistant
8. This application replaces the phone name to Pixel XL 😂
