Oh Happy Day
Is the charger plugged in and the screen stays black? It doesn't have to be. Also for Android there are screensavers. In order to save the battery, it is only active when the Charger is plugged in.
... and then numbers dance on your screen and show the time precisely.
You can find this screen saver in the Google Playstore. Please click here to download the program to your smartphone or tablet.
