Say "free up 5 GB." Your AI butler handles the rest. Cleaning your phone shouldn't be a chore. Cleaner AI works like a personal assistant: tell it what you need — a goal, a task, or just "my phone is full" — and it goes to work. It finds what's eating your storage, decides what's safe to remove, and takes care of it. You get the space back. You didn't lift a finger. AI picks a suggested set. You review every photo. Nothing is ever deleted without your tap — your memories stay safe. NEW: EMAIL CLEANUP — TAKE BACK YOUR INBOX Your email is the other half of "messy."
