Network Type Indicator is an interesting tool that gives you the possibility to know what type of Internet connection your Android device is using at all times.
Network Type Indicator couldn't be easier to use. Once you have the app open, it'll explain what each symbol represents and will tell you what type of connection you're using at that moment. It also tells you the signal strength and if you're using mobile data or not.
One of the most interesting features of Network Type Indicator is that the app keeps working, even when closed. This is really useful for devices that don't include this type of indicator by default.
