Black background for phone — glowing cyan code

Glowing cyan digital text and circuit lines run down the right edge of a pitch-black screen. Since this design is mostly true black, the black pixels switch off on AMOLED and OLED panels to save battery. The file is rendered in high resolution with a vertical 9:16 aspect ratio to fit your device without cropping.
