220-1102 Practice Question: That their Android phone automatically switches…
A user reports that their Android phone automatically switches from Wi-Fi to cellular data when the Wi-Fi signal is weak, even though they want to stay on Wi-Fi. Which setting should you configure to prevent this behavior?
⚠ Common exam trap
Watch out — candidates often confuse 'Mobile data always active' with the automatic switching feature; candidates often think that disabling mobile data entirely will solve the issue, but that would also prevent cellular fallback when Wi-Fi is truly unavailable.

Correct answer & explanation
✓
Disable 'Switch to mobile data' in Wi-Fi settings
The 'Switch to mobile data' setting (sometimes called 'Auto-switch to mobile data' or 'Smart network switch') is specifically designed to automatically fall back to cellular when Wi-Fi becomes unreliable. Disabling it forces the phone to stay on Wi-Fi even if the signal is weak, which is exactly what the user wants. This setting is found in the Wi-Fi preferences or advanced Wi-Fi settings on most Android versions.

- ✗
Turn off Bluetooth
Why it's wrong here
Turning off Bluetooth would not resolve the issue of an Android phone automatically switching from Wi-Fi to cellular data. Bluetooth operates on a different radio frequency (2.4 GHz, distinct from Wi-Fi's primary channels) and is exclusively designed for short-range device pairing, such as connecting peripherals like headphones or smartwatches. It has no direct influence or control over the device's Wi-Fi connectivity or its internal logic for transitioning between Wi-Fi and mobile data networks.
- ✗
Disable 'Mobile data always active' in Developer Options
Why it's wrong here
Disabling 'Mobile data always active' in Developer Options will not prevent the phone from automatically switching from a weak Wi-Fi signal to cellular data. This specific setting primarily ensures that the mobile data radio remains active in the background even when connected to Wi-Fi, allowing for a quicker transition to cellular data if Wi-Fi becomes unavailable or for specific background services. It does not, however, override the system's primary logic for proactively abandoning a weak Wi-Fi connection in favor of a stronger cellular signal.
- ✗
Enable Airplane Mode
Why it's wrong here
Enabling Airplane Mode would be counterproductive and would not solve the user's problem of unwanted automatic switching from Wi-Fi to cellular. Airplane Mode is designed to disable all wireless communication radios on the device, including cellular, Wi-Fi, Bluetooth, and GPS, to comply with airline regulations. While it would stop the phone from using cellular data, it would also disable Wi-Fi entirely, preventing the device from connecting to any Wi-Fi network at all, which is the opposite of the desired outcome.
- ✓
Disable 'Switch to mobile data' in Wi-Fi settings
Why this is correct
Disabling the 'Switch to mobile data' (often labeled as 'Wi-Fi Assistant' or 'Smart Network Switch' depending on the Android version and manufacturer) option within the Wi-Fi settings directly addresses the user's reported issue. This feature is specifically designed to automatically transition the device from a weak or unstable Wi-Fi connection to a more reliable cellular data connection to maintain internet access. By deactivating this setting, the Android phone will prioritize staying connected to the Wi-Fi network, even if the signal is poor, preventing the unwanted automatic switch to mobile data.
