OK for storage issues this is what works for me, I used to always have to delete stuff to get more storage, but what I learned was if you delete your apps like Instagram, it deletes the cachet that’s taken up your storage, so you log out, then log back in, and then the apps that I’m not using, I offload the apps that I don’t use on a daily basis and then you also have to clear your Google search, also you know how you may send a video through your text, that is a large attachment so if you go into settings, then general and then storage you can view your large attachment. The ones I wanna keep i save but the other ones I delete and that will free up your storage. Hope this helps.
