If that is a device, and it's powered on and is making sounds, the screen may have failed.

Welcome to Android Central! Do you mean your imo app only shows a black screen? Try going to Settings>Apps, select imo, and Clear Cache/Clear Data. Now open it again and log back in. Does the same thing happen?
