The world of Android modification never stops moving! While many are still waiting for stable Android 16 updates, we’ve managed to get the Android 17 Beta 2 GSI (Generic System Image) running on the Nothing CMF Phone 1. This device continues to be an incredible platform for enthusiasts who want to taste the future of mobile software.
In this guide, we’ll walk you through the installation process and see how it holds up in a side-by-side comparison with Android 16.
Preparation: What You’ll Need
Before jumping in, remember that GSIs are experimental. This process will erase all data and may void your warranty.
- Unlocked Bootloader: Mandatory for any GSI installation.
- ADB & Fastboot Tools: Installed on your PC.
- Android 17 Beta 2 GSI Image: Download the correct ARM64 binary.

Initial Impressions & Verdict
The first thing you notice is the smoothness. Android 17 animations feel more polished than ever before, making the CMF Phone 1 feel faster. Other than that, there isn’t any major visible changes.
Is it worth the update? For developers and curious techies, yes. For everyone else, it’s best to wait. While the new AI features and refined UI are enticing, the GSI lacks the specific “Nothing OS” optimizations that make the CMF Phone 1 hardware shine.
