Can Old Photos Be Recovered After a Factory Reset on a Redmi 13C 5G?
TL;DR:
A buyer should not be expected to recover old internal photos from a Redmi 13C 5G using normal undelete software after a factory reset because Android's file-based encryption protects user storage with encryption keys.
● Failing to sign out of the Xiaomi account before resetting will not expose the deleted files, but it can trigger a Find Device activation lock that blocks the new owner.
● Sellers must manually remove account linkages to prevent activation blocks and physically extract any microSD cards, since a standard device reset does not guarantee external storage sanitation.

After a completed Settings factory reset on a Redmi 13C 5G, a buyer should not be expected to recover the previous owner's ordinary internal photo library with normal undelete software. Xiaomi states that the factory-reset process erases the phone's data, settings, apps, and personal information, while modern Android devices use file-based encryption for user storage.
The owner in this Redmi resale privacy question had already deleted personal photos and videos, reset the phone from Settings, left it at the initial setup screen, and had not used it again. The remaining worry was whether a buyer or professional recovery shop could restore those old files because the Xiaomi account had not been signed out first.
The Factory Reset And The Xiaomi Account Are Different Problems
Xiaomi's REDMI 13C 5G factory-reset documentation says the procedure erases all data and personal information on the device. Android's file-based encryption documentation states that devices launching with Android 10 or later are required to use FBE, where user files are protected by encryption keys rather than existing as ordinary unencrypted deleted sectors.
That does not justify an absolute claim that every forensic technique on every implementation is impossible. It does mean this is not the same recovery problem as deleting photos from an unencrypted SD card, and ordinary file-carving software should not be expected to reconstruct the previous internal photo library after the completed reset.
Forgetting to sign out of the Xiaomi account mainly affects ownership and activation. Xiaomi documents that enabling Find Device links the phone to the Mi Account and can require the linked account password after a factory reset. Xiaomi's Find Device guidance also explains how to remove a device from the account.
Before Sale:
- Leave the phone at setup: Do not sign back in and repopulate it with personal data.
- Remove account linkage: Check Xiaomi and Google device/account settings so the buyer is not blocked by an activation requirement.
- Check removable storage: If a microSD card was used, remove and handle it separately; the phone reset should not be treated as proof that a separate card was sanitized.
