I specifically asked survival of cell/mobile phones in on or outside MH17 for a reason. Most/many phones are u/s when falling more than 10 feet. many worked after MH17 to the point the death cert was not required to block the phones. As far as ELB/T g force survival on g force there are none but many/most are solid sate. And can withstand a lot (seems except aviation approved hand held ones). I don't know if more on an aircraft would help, but I know here if you wish to carry your own on an airline it is not permitted generally but can get a approval if wanted but about the same as carrying a firearm on an aircraft.
