GoKawiilOld Android phones can double as Wi-Fi extenders via built-in hotspot
An old, otherwise unused Android phone can be repurposed to extend home Wi-Fi coverage into dead zones without buying new hardware like extenders or mesh nodes. Users can rely on the phone's built-in hotspot feature, which lets it connect to an existing Wi-Fi network and rebroadcast the signal as a repeater, requiring no extra apps or technical skill.
