You can transfer all data from one Android phone to another using several built-in methods, with Google Account being the simplest and most complete option.
Using Google Account (Recommended): On your new phone, sign in with the same Google Account used on your old phone during setup. Android automatically restores apps, contacts, calendar events, photos (if using Google Photos), Gmail, and many app settings. This works across any Android phones and doesn't require a cable.
Using Samsung Smart Switch (for Samsung phones): If both phones are Samsung devices, download Smart Switch on both phones. Use the wireless or wired connection option to transfer contacts, messages, photos, videos, apps, settings, and more. A USB adapter allows direct cable connection for faster transfer.
Using Android's Built-in Transfer Tool: On the new phone during initial setup, select "Copy apps and data from your old phone." You can use Wi-Fi or USB connection to transfer apps, contacts, messages, photos, and settings directly from your old device.
Manual Methods for Specific Data: For selective transfers, use cloud services: Google Drive or OneDrive for files, Google Photos for photos, and your email provider for messages. Contacts can be exported as .vcf files and imported on the new phone.
Tips: Charge both phones fully before starting. Keep them near each other for wireless transfers. Some third-party apps may not transfer automatically—you may need to reinstall them from the Play Store. Verify that sensitive data like banking apps are reconfigured with proper authentication on the new device rather than relying on automatic restoration.
