220-1102 Practice Question: That their Android phone automatically switches…

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  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.
