Hi Peter Yoon,

For Android 14 on RPI 4 (with 2 GB), any further updates ?

Like, 
1. VPU,
2. GPU,
3. Display,
4. WiFi/BT (I belive its done ),
5. Ethernet (may be done too),
6. Storage (Sd/emmc),
7. camera,
8. Audio playback & recording,
9. UI performance

And any other (if missed) ?

Appreciate your support in understanding.
