How To Make Your Android Automatically Switch to the Strongest WiFi Network

Wi-Fi signals have limited range, so if you live in a two-story house or work in a larger office, you may have set up multiple routers or repeaters to ensure full wireless coverage. Sadly, Android handles the transition between networks pretty poorly.

The main issue here is that Android won't disconnect from the first Wi-Fi network until the signal strength drops all the way to zero. When this happens, your device won't switch to another network, even if it's stronger and closer than your original network.
