If you had paid attention to the pre flight safety brief you should have noted the bit about turning off electronic devices.
It amazes me how many people on pax flights ignore the cabin crew brief and demo.
It is there for everyone's safety!
It is also very rude to ignore the cabin crew at this time.
Ryanair CC used to stop the demo if everyone wasn't paying attention. I don't know if they still do, but I think all airlines should do this.
Rant over.
Safe flying.
