I live in a house where the router seems to just turn off every now and then. It's not really a problem as long as I'm aware when my phone switches to data, but sometimes I'll have watched multiple videos before I notice the lack of a wifi symbol. This is definitely a problem because I have a limited data plan.
I have a Galaxy Note 5. Does anyone know of a simple way for the phone to warn me when I drop off wifi?
I don't think Android devices have a built-in alert or notification to cater for this
You can achieve this by automation. I prefer MacroDroid being easy to learn and free ( upto 5 macros )
Trigger: WiFi state change → Disconnect from network → choose network or any
Actions:
Play sound → Choose a sound from drop down list.
Popup message → Type whatever you want to be displayed when Wi-Fi is disconnected.
This will give you an audio alert + a pop-up message on your screen.
