SaranWhile I understand what you mean insofar that there is no need for "Network speed" to be shown when the device is in Flight Mode or with Data turned off - but to take the reasoning an extra step in saying that "because you see network speed at 0 B/s - you think data is ON when it is not" is quite a fringe case.
There should be an option for automatically hiding the network speed meter when internet is turned off . Sometimes it shows data flow even though network is turned off, I know data can't flow if network is turned off. It's just I open chrome or any network related apps thinking data is turned on because of this leading to the those apps telling me to turn on internet. It's just bad user experience. @Anders_ASUS @CH_ASUS
