Detailed features

Feature or features	Status	Notes
Proximity sensor Light sensor Accelerometer Magnetometer Compass Gyroscope	Y	Tested using ssccli
Battery	Y	ADSP takes care of it
Audio	P	What works: - Top speaker - Bottom speaker - Top microphone - Bottom microphone - Left headphone channel - Right headphone channel - DisplayPort left channel - DisplayPort right channel - DisplayPort automatic detection What doesn't work: - Automatic headphone detection - Headphone buttons - Headphone microphone - Sending audio to modem - Receiving audio from modem Speaker volume is too low, no active speaker protection in place so volume is artificially limited for safety. Audio clipping can be heard when using headphones.
Camera flash	Y	Both flash and torch modes work properly.
Calls	P	While calls work properly, you can't send or receive audio!
SMS	Y	Working properly
NFC	Y	Card detection works.
Touchscreen	Y	Working properly
Wi-Fi	P	While Wi-Fi works properly, the connection range is extremely short. Trying to load board files makes the Wi-Fi card crash.
Bluetooth	P	While Bluetooth works properly, the connection range is extremely short. Most likely related to Wi-Fi sharing some circuitry according to device schematics. Trying to load board files makes no difference.
Mobile data	Y	I guess it works? I haven't noticed any problems with it. Tested with 3G, 4G and 5G NSA.
Haptics	N	No driver available
Fingerprint sensor	N	Connected through SPI. GPIOs are protected by Motorola-signed hypervisor. Access is only allowed to Motorola-signed trusted app.
USB networking	Y	I guess it works?
Screen	Y	It works!
UFS	Y	Max frequency should be 850MHz (SM8475), but actual frequency is 849.999902MHz. Left as is at 300MHz (SM8450).
3D acceleration	P	- Glitches can be seen sometimes. - The GPU crashes sometimes.

UART

Note that if Phone RX is left floating, the bootloader will not output anything to Phone TX!

The bootloader outputs data at 115200 bauds. Logic level is 1.8V.

GND must be grabbed from somewhere. Good luck!
