I obviously have this phone because it was cheap and I thought nice. It is a 16gb phone. For some reason the storage space is low. I have deleted all pictures, all apps, and clear the cache constantly. All I have on my phone is Facebook Messenger. It went from 1532 gb full to 15.60 gb full. I went to Cricket for help and of course they wanted to sell me a new phone. How do I fix this storage space issue?
