The risk is only while the Samsung device is charging (as I recall?). As for other devices, I suppose they could issue the warning "please do not hit your device with a hammer during flight".

Fun fact I read recently: more than a million people are in the air at any one time, globally. If laptop batteries exploded even rarely, we'd hear about it.

The Aviation Herald lists a few incidents involving batteries:

Nice find. No doubt batteries are a hazard particularly when exposed/not installed in devices as many of these examples describe... batteries found squashed between the seat and so on. If we remove cases of smoking loose batteries, or crushed devices in luggage, the failure rate is extremely low.

It depends on the mode of failure, but these problems happen when a battery is stressed. Charging or discharging at a high rate especially with high temperatures and during/after physical stress can cause runaways.

Protection circuitry is supposed to prevent runaways, something is obviously failing. It could be an overheating component or faulty high voltage protection circuits or simply just bad thermal design.
