Reset Network Settings auf Realme
Persistent Wi-Fi drops, failed Bluetooth pairing, or mobile data that won't connect usually point to a corrupted network profile rather than a hardware fault. Realme UI stores Wi-Fi passwords, paired Bluetooth devices, and carrier network parameters separately from the rest of the system, so a full factory reset is not required to fix them.
Resetting network settings clears this stored profile and forces the phone to rebuild it from scratch the next time you connect. This solves most cases where a specific Wi-Fi network refuses to reconnect, Bluetooth accessories fail to pair again, or mobile data stops working after a SIM change.
To reset network settings, go to Settings ➔ Additional settings ➔ Back up and reset. On this screen, open Erase all data (factory reset) and select Reset network settings, then confirm with Reset network settings again.
After the reset, you need to rejoin every Wi-Fi network manually and re-pair Bluetooth devices. Personal files, apps, and photos stay untouched. If the connectivity problem started right after a system update or app installation, check for a pending software update first, since that can resolve driver-level issues without wiping any network data.
