Why won't my Galaxy S5 automatically connect to 4G after being connected to wifi?

[AC Question]

why wont my galaxy s5 automatically connect to 4G after being connected to wifi?

I can not get my galaxy s5 to automatically connect to 4G after being connected to wifi, the smart network switch is activated however it doesn't make any difference. the only way for me to reconnect to my network is to restart the device.
