Phone Backup and Transfer Guide
Prepare reliable backups before repair, reset, sale or moving to a new phone.
A backup is useful only if it completed recently and includes the data you care about. Some apps and authenticator tools require separate transfer steps.
Start with the safest checks
Use observation and reversible tests before changing settings. Write down the exact message, recent changes and conditions that reproduce the problem.
- Inventory photos, messages and app data
- Verify the backup timestamp
- Check authenticator and password access
- Keep the old phone until the new one is verified
- Erase only after successful transfer
Protect your data and accounts
Back up important information before repair, reset, sale or transfer. Never disclose passwords, one-time codes or full device identifiers in public.
- Verify backup completion
- Use official account-recovery channels
- Keep sensitive identifiers out of screenshots and URLs
Know when to stop
Stop when a phone is swollen, smoking, leaking, physically damaged or extremely hot. Manufacturer, carrier or qualified repair support is appropriate when safe checks do not isolate the fault.
- Do not puncture or open a battery
- Do not use heat, freezing or conductive tools
- Ask about warranty, data handling and cost before repair
