Android 5.0: WORKS!
Android 4.4: does not generally work; some devices may work with dummy Wi-Fi trick though.
Android 4.3 down to 4.0.3: web browsing WORKS; dummy Wi-Fi or a similar trick required for other apps.
These notes apply to the TABLET-side app ONLY. Regular EasyTether works on all Android versions.
Install on your tablet and follow the instructions.
EasyTether Tablet provides Internet connection shared from your smartphone using USB or Bluetooth.
USB tethering requires USB host cable (also known as USB OTG cable)!
If you need to tether your smartphone to your computer, see the smartphone-side EasyTether application.
A known issue:
Apps that ask the system if there is an Internet connection do not work.
It happens because the system does not treat VPN connection without underlying Wi-Fi, 3G or 4G connection as Internet connection. It does not matter if you use the Lite or the full EasyTether on your phone.
The workaround is to connect to some dummy Wi-Fi network (without Internet access).
