Black Screen APK

Black Screen: video screen off – an application that offers users to start significantly saving battery power by applying a black canvas on top of their main desktop. One click will be enough to enable or disable this mode of operation. Which can really seriously affect the duration between recharges. Mostly all this is intended for owners of smartphones with AMOLED and OLED screens. Due to the fact that the black color on them practically does not require any costs on the part of the battery. This makes the project worthy of attention.
