Reset Network Settings on Android auf Android
When a phone keeps dropping Wi-Fi, refuses to reconnect to mobile data, or forgets paired Bluetooth accessories, the cause is usually a corrupted network profile rather than a broken radio. Android stores every Wi-Fi password, APN entry, and Bluetooth pairing key in a dedicated settings database. Over time that database can pick up conflicting entries, especially after a system update or a failed connection attempt.
Resetting network settings clears this database completely. Wi-Fi networks, saved passwords, Bluetooth pairings, and mobile network configurations get wiped and rebuilt the next time you connect. It does not touch apps, photos, or personal files, so nothing outside connectivity settings is affected.
You reach the reset menu under Settings ➔ System ➔ Reset options ➔ Reset Mobile Network Settings or Reset Bluetooth & Wi-Fi ➔ Reset. Some Android skins combine both options under a single network reset entry.
Skip this reset if only one specific network or device is causing trouble - forgetting that single Wi-Fi network or Bluetooth device is faster and avoids re-entering every other saved connection. Use the full reset when multiple connection types fail at once or when a factory reset would be too drastic a step.
