Example of new Frontlight API in 3.4 firmware

[calin-darie]

Hi!

I have a few reports of people with Tab Ultra / Tab Ultra C / Palma devices, all on firmware 3.4, where the old CTMBrightness methods are failing.

Which API should I use?

Alright, found something

Is onyx.sdk.device 1.2.26 published?

One thing I still can't figure out: what system properties are being changed by the new CTMBrightnessProvider and CTMTemperatureProvider

For the old API, the system properties used to be
content://settings/system/screen_cold_brightness
and
content://settings/system/screen_warm_brightness

I need these in order to react to changes outside my app. It's also a good way to know when changes made by my app have taken effect, without polling.

Hi @Edward259 , can you please hellp?

You can monitor the changes in these values in CTM type, and I noticed that your app has been adjusted.
content://settings/system/screen_ctm_brightness
content://settings/system/screen_ctm_temperature
content://settings/system/ctm_brightness_state_key
content://settings/system/ctm_temperature_state_key
