This is one of the most common questions we receive. The honest answer: after a factory reset, recovery apps – including DS Recovery PRO – usually cannot bring your old files back.

Why

Modern Android phones encrypt their storage. A factory reset deletes the encryption key, so the old data can no longer be read by any app, even if parts of it are still physically there.

Where to look instead

Google account: photos in Google Photos, contacts, and the device backup offered when you set up the phone again.
Your phone maker's cloud (for example Samsung Cloud, Xiaomi Cloud).
Chat backups: WhatsApp and Telegram can restore media from their own backups.
An SD card: files stored on a removable card are often not erased by a phone reset. Scan the card with DS Recovery PRO.

For next time: turn on automatic backups in your Google account and keep important files in two places.
