Google One

Google One does two jobs, and the first one matters most on the day something goes wrong. It backs up the parts of your phone that cannot be replaced by buying a new device: photos, contacts and messages. The backup runs automatically in the background, so it keeps working long after the enthusiasm of setting it up has faded, which is precisely when phones get dropped, stolen or simply stop turning on. Restoring to a new Android device brings that material back rather than leaving you rebuilding a contact list from memory. The second job is making your storage comprehensible. Every Google account includes fifteen gigabytes, shared between Drive, Gmail and Photos, and the usual experience of that limit is a warning message with no explanation of what filled it. The app shows the breakdown across all three services in one place, so you can see whether the culprit is years of email attachments, forgotten files in Drive or the photo library, and clear space where clearing actually helps. A paid Google One membership raises the limit to whatever plan suits you, and the app is where you compare plans, subscribe and manage the subscription. The free features work without paying, so backup and storage management are available whether or not you upgrade.
