One tap to switch to a specific Wi-Fi network!
Unlike other similar apps, this app does not do background Wifi scanning, i.e. this app DOES NOT drain your battery.
Note: The app does NOT work on the new Android 10 phones, because Android banned the control of Wi-Fi from app. I haven't yet found workaround.. I don't have Android 10 phone too.. very hard for me to do testing..
Note: On some phone models, if you see the app pops up every time when you clicks the widget, please close the app from background running, or just reboot the device. If this does not help, sorry to say, I cannot make the app works on all phones.
