My question is not a duplicate of this post as in that the OP is asking for the difference between the network icons for a rooted device whereas mine is for mobile signal icons in an un-rooted device.
Mine is a Samsung trend phone with Android 4.1.2.Every time i check my phone for any signals it shows full but in the notification tab(the area displaying the network name) displays no network.
When there is 1 bar and not greyed out i am able to receive messages but when it's full with a surrounding grey box there is again no network and some times it also display's a small triangle with an exclamatory symbol in it when the phone signal is completely empty bars.
I am confused and unable to differentiate how does Android 4.1.2 display the different availability of phone signal icons.(i.e. No signal,Full signal, etc)
Note:-I would be adding the screen shots of the device shortly .
