Good days . Just having my brand new SM-N9005 for one days ... I found out the HsDPA or 3G or 4G automatically to sleeping mode ...
I have to flip over the SCover only able to re-stable back the Data Network .
Well Example below :-
WhatsApp . I use S4 to send WhatsApp to N3
Wait for 5minute was no notification at all untill I switch on from standby ...
The incoming WhatsApp notification will show out after this ....
Please help to figure out what issue
