You can try
Shou, it can record some Android phones under 4.4... But
Most if not all Android screen recorders for 4.4 and under needs root. On 5.0 and up there's a feature added to Android called "cast", it lets you record without root.
There are some apps that let you record your screen when connected to a pc. If you don't have a pc, then you maybe out of luck.
