All I find is suggestions from a few years ago, so probably outdated or maybe there appeared some better tools in the meantime, there are some apps in the play store but I need something good privacy wise, no training demon, also small battery life impact would be nice
For your unfamiliar with moto gestures I’m talking about are chop for flashlight and twist for camera, they work irrespective of app you’re in or screen being on/off
Also changing songs with volume buttons was nice
Well, this post is currently only about those two features, and there are only a few OK suggestions. And to also get the display and gaming features, you’d need much more work. Extracting the Moto apps as APKs wouldn’t work, as they require many daemons and services running in the background. So the only way to get those features that I see is to install the Moto ROM directly. There are all ROMs available, though they aren’t from Moto themselves. I do not think flashing it on another Phone would really work tho. So the only way I see to get all features perfectly would be by actually buying a Moto Phone.
The only downside of Moto Phones is the Camera, really. The 700€ edge 40 Pro is only behind the Galaxy S23 Ultra in Camera, display resolution (though who really needs 4k?) and battery size, but has a higher Hz refresh rate, 4 GB more RAM and charges nearly 3 times as fast. I personally got the Edge 20, which is more than enough (except for the camera). The latest to fully support bootloader unlocking and therefore Lineage is the Edge 30 tho, afaik.
