ZTE has to be the worst phones ever made it freezes alot I barely have any apps on my phone and says it need more space I will never use another ZTE
The blade spark should have 16GB of NAND with around 5 or so GB taken up by the system partition.
Storage can be expanded by a micro SD card
As for freezing issues, check to see if you have any corrupt or malicious apps installed. Some applications can provide desired user functions but also have malicious or unwanted background activities, e.g., some may use up system resources in order to spy on other apps and activities that is done on the device.
One application you can use in order to view items in your system startup, is 3c toolbox https://play.google.com/store/apps/details?id=ccc71.at.free
In the expert mode, you can click on the "Startups" icon and see what is set to run in the background at startup.
