why wont my s5 automatically connect to 4g?

Since I have updated my galaxy s5 my fone no longer goes between WiFi & 3g/4g. When I leave a WiFi connection I have to restart my phone to connect to a mobile network. It works the other way, mobile to WiFi

Welcome to Android Central! Go to Settings>Wi-fi, tap Menu>Advanced, and make sure Smart Network Switch is turned off. See if that works.
