Xiaomi has not released Android Marshmallow for Redmi Note 3 SD yet. I am sure Redmi Note 3 users are eagerly waiting for Android M.
No more wait! Test the feel of Android Marshmallow with Cyanogenmod 13. This the unofficial build of CM 13 for Redmi Note 3 but works perfectly fine.
These features works perfectly fine on CM 13 (Android M):
- GPS F
- Fingerprint scanner
