The Razer Phone 2 may be a compelling new option for Android users who would like a screen with a 120-hertz refresh rate and dual front-firing speakers. It is also one of the few mobile devices on the market with a back-plate logo that lights up and can be programmed in terms of color and frequency. Razer's take on this technology is called Chroma, and is controlled by a system app of the same name.
However, this innovation is also a double-edged cosmetic sword. Some Android users like the option to unlock their bootloaders, and also gain super-user access, so that they can install custom ROMs that keep the phones in question fresh, up to date or both. Unfortunately, in the case of the Razer Phone 2, doing so could forfeit access to the Chroma app, without which the back-light may not work.
However, a developer called CurstiMJ has addressed this problem by compiling Logo+. This new app is an open-source facility that does what Chroma does on a rooted Razer Phone 2. A user can choose a different LED color for each different app, change the LED's brightness, split the logo between up to reflect notifications from 4 different apps at once, and program a range of passive effects, with this interface. Logo+ is available for download now, although it should be noted that the app is still in beta at the time of writing.
