Factory Reset via Settings auf Realme
A factory reset on Realme phones removes every user account, app and file, then reinstalls the original software state as it left the factory. This includes linked Google accounts, downloaded apps, saved photos and videos, documents, and all app-specific data stored on the device.
When a reset makes sense
Use this option when the phone runs slow after months of use, when you plan to sell or hand over the device, or when persistent software glitches do not go away with a simple restart. If only one app misbehaves, clearing that app's cache or data is usually enough and does not require wiping the whole phone.
How to start the erase
Open the menu path: Tap on Settings ➔ Tap on Additional settings ➔ Tap on Back up and reset ➔ Tap on Erase all data (factory reset) ➔ Tap on Erase all data ➔ Tap on Erase data.
Confirm your PIN or fingerprint when asked. The phone restarts automatically once the erase finishes and boots into the initial setup screen, the same one you saw when you first unboxed the device.
Before you confirm, make sure any photos, chats or documents you want to keep are already backed up, since none of this data can be restored afterward.
