On most Android phones, Google Drive is already there before you install anything. It is the storage layer under Gmail attachments, Google Photos backups, Docs and Sheets, WhatsApp chat backups, and the files app on many devices, all drawing from the same free 15 GB allowance tied to your Google account. That integration is the product: Drive rarely wins on raw features, but it is where your files already are.
The app itself handles uploads, offline access, scanning paper documents, and shared folders competently. The questions worth asking are about the fine print: how sharing links behave when you create them, what Google's automated scanning does and does not look at, and how quickly that 15 GB fills once Gmail and Photos start counting against it. This review walks through each, plus when a Google One upgrade actually makes sense.
Backing up and reaching files anywhere
Documents uploaded from a computer are on your phone seconds later, and the document scanner turns paper receipts and contracts into searchable PDFs. For people living in the Google ecosystem, this is zero-setup infrastructure.
Collaborating on Docs and Sheets
Drive is the container for Google's office suite. Shared folders keep a team's files organised with per-person permissions, and comment notifications land in Gmail. Version history quietly saves you from most editing disasters.
Moving big files between people
A sharing link beats email attachments for anything over a few megabytes. You control whether recipients can view, comment, or edit, and links can be restricted to specific accounts rather than anyone who obtains them.
15 GB free, shared across services
The allowance covers Drive, Gmail, and original-quality Google Photos together. That is generous against rivals until you realise years of email and photo backups count too; the built-in storage manager shows what is eating the space.
Granular sharing controls
New shares default to restricted: only people you explicitly add can open the file. Making a link public is a deliberate switch, and viewer, commenter, and editor roles are enforced per person or per link.
Offline access
Marking a file as available offline keeps a synced copy on the device, and Docs, Sheets, and Slides can be edited offline with changes syncing later. It is opt-in per file, so mark what you need before a flight.
Built-in document scanner
The scan button captures paper documents with automatic edge detection and saves searchable PDFs straight to a folder you choose. Text inside scans becomes findable through Drive search, which makes it a genuinely useful filing system.
