My Moto G (1st Gen 4G LTE version, Android version 4.4.4) from AT&T prioritizes mobile data connection even when wifi is available. I will attempt to connect to the wifi connection in setttings, and once I hit "connect" it will attempt to connect, then "connect," but then immediately say "disabled" and stay connected with 4G. I have to turn off mobile connection, in which it will then connect via wifi and then I can re-enable mobile (while still connected via wifi). While this works, I like to avoid using data when its not necessary, and its annoying to have to remember to do this every time I use my phone for anything other than phone calls. Any tips/info would be greatly appreciated.
