Turn Airplane Mode On or Off auf Oppo
Airplane mode on an Oppo phone disables every radio at the same time: mobile network, WLAN, Bluetooth and NFC. This is why apps that rely on background data, like messaging or navigation, stop working the moment it gets switched on, even if you only meant to save battery.
On Coloros, the toggle sits inside the connectivity settings rather than in a separate menu. Open Settings ➔ Connection & sharing ➔ Enable or disable Airplane mode to switch the function on or off.
When you turn Airplane mode off again, the phone does not simply reactivate everything. It reloads only the state each connection had before you enabled Airplane mode. If WLAN was off beforehand, it stays off afterward, which explains why some people think their WLAN is broken when it is actually just following its previous setting.
If you only need to disable one connection, such as mobile data or Bluetooth, turning it off directly is faster and avoids interrupting the others. Airplane mode makes sense mainly for flights, quick full disconnects, or troubleshooting network issues where every radio needs a clean restart.
