I'm looking for an App that tells me when my phone has switched to 4G. Ideally notifying me with a sound of my choosing.
I've looked at Tasker and AutomateIt, but both seem overly complicated for the sake of one task. A bit like using Photoshop just to resize a picture.
Does anyone know if one exists? Or failing that, a simple way to get Tasker or AutomateIt to do it?
I'm using a LTE S4.
