Update 1
I see a framerate/refresh rate bug that occasionally locks the framerate at a low value upon unlock. Fixing it requires a lock/unlock cycle.

Does the flashlight led have multiple brightness levels?
Tried flashdim from F-Droid, doesn't seem to work.
Best app ever
Never heard about it. Works great in Pixel 8!
that's an android feature. technically I think any phone could do it.
If the hardware isnt able to switch the LED at least like 200 times a second, then it cant do proper PWM that doesnt look flickery so no you can definitely have a phone that isnt capable of it.
Why would they use PWM to drive an LED in a DC circuit when they could just drop the voltage to make it dimmer?
Could be done but voltage regulators just burn a bunch of energy which doesnt seem very smart for a mobile device. Also if you already need a transistor for switching the LED then just picking one that can do so at 200Hz or more is gonna save you an extra part and give you much finer and easier control over dimming.
