WiFi mode is now supported on Verizon Samsung phones updated to Android 4.4 (KitKat). That includes Galaxy S5/S4/S3 and Note 4/3/2. We do not have a solution for other models so please stay with USB/Bluetooth mode for now.
There is also a way to remove the lock screen if you don't like it, please see descriptions!
A Bluetooth issue introduced in 2.16.2 is fixed in 2.16.4.
