Ooo.. I am not so much of a Samsung fan or any android phone. I find that the phone is always downloading and installing something that I have no idea what they are. My mom had a Samsung once and the phone is always giving a storage space warning. It was really frustrating to always try to figure out what is chewing up the storage space :D
@marblely the phone indeed lives it's own life but it's mainly google and you need to.switch the same things off at 3 different places.
My daughter has a storage lack too. She says it's because of the uodates. To save storage it's the best to remove the app(s) and install.them new.
