It needs a screen it damage from inside but its cheap if you fix with none original parts which is $25-$35 but if you fix it with originals its like $45-$60
The lcd is broken cause the black spots and the glitch its showing its the lcd thats broken and the digitizer might be broken if you touch the screen from the outside you should feel cracks if not its working but the lcd is broken. I fix IPod, iPodTouch, and iPhone. Also the fake parts are cheaper but they don't always work well its better getting original parts which is $45-$60
