Lack of xenon flashes in cameraphones
I did wonder why there aren't many phones with xenon flashes. I guess there could be several reasons for this:
- accommodating the large capacitor
- the safety issue of a large capacitor charged to a few hundred volts waiting to be dropped in the toilet and fished out again
- the RF interference from a large capacitor effectively being short-circuited when the tube fires potentially frying one of the radio receivers. I guess there could be quite a lot of RFI generated while it is being charged, too, and that could go on for several seconds.
