It's a totally different affair if you are receiving a signal by a 100 Watt transmitter at 10 Km or a signal from a 1 Watt transmitter at 5 meters distance. The 1 Watt transmitter will overpower anything in its band with great ease and any dirt on the spectral output will have the same effect in other bands. Note that most cellphones will crank up their output if they can't connect to a base station that they can receive.

Of course plane designers will still do what they can to reduce this nuisance but leaving our phone on makes it harder than it should be. Please turn your phone off or to airplane mode and consider it a very small price to pay for flying an airplane.

Yes, flight mode does matter, no it probably won't crash a plane but does it have to before you would consider following a very simple rule?

But, more importantly, it puts your phone's radio through an unusual high-power-draw situation that the phone's manufacturer may not have bothered testing for, which can make phone batteries explode that might not have otherwise ever exploded.

Oh, and also, a plane-load of people whose phones are all ranging hogs circuits on a bunch of towers at once (for no productive purpose, since the phones don't have high-enough SNR to actually communicate anything useful with any of the towers they can "see"), so the cellular service providers have politely asked the FAA to get people to not do that.

It was fairly straightforward to replace the ad images. Now it shows me cat pictures when turned off.

Kindle Voyage 1st generation, if that's relevant.

I just use a Kobo now.

Edit- my bad, it was a Hitachi. The vizio tv I have was purchased last year. However both are dumb, they have no internet capabilities at all

Which is great news - they are fantastic displays, they last forever, and they behave just like a very big computer monitor.

NEC commercial displays (P461, for instance) are not expensive. I highly recommend you look into it.
