Once in awhile the internet will drop on the network that my phone is connected to via Wi-Fi. It's pretty rare, but in instances when it happens, my phone remains connected to the network but won't receive notifications. I won't know that it's not connected unless I'm intentionally attempting to do something that requires internet access at which point I can just disable Wi-Fi.
I imagine that my phone should be able to figure out it no longer has internet access even if it's connected to a network. Is there a way to have it failover to the provider's 4G/LTE connection when this happens?
My device is a Galaxy S6 Edge+ running Android 5.1.1
