Aeroplane mode and mobile data

[Elmo5]

The aeroplone mode should shut down all the wireless communication methods but the mobile data symbol remains lit. This looks like a bug although in reality it looks like the mobile data doesn't connect when in aeroplane mode.

But why doesn't the symbol turn dark like the wifi symbol?

This was present with android 4.1.2 as well as 4.3.

In Aeroplane mode Wi-Fi can still work - Phone calls etc will stop as well as Mobile Data as it's the Sim card that gets disabled - Are you getting the symbols mixed up?

Nope, the texts underneath the symbols are clear.

Once I switch the aeroplane mode on, wifi symbol goes dark but mobile data symbol doesn't. Still it doesn't connect to the operator network. Neither can I call. So it functions correctly but the symbol is misleading.

You are right about wifi, I can turn it on manually and it connects.
