The only software update that i know of for that plane was an update to the LSAS after the crash at Narita in 2009. But I wouldn't think that Boeing would skimp out on that.
Having a phone that is waterproof or water resistant was a remarkable and even optional feature not that long ago. For example of waterproof being optional consider the folding phones none of which are waterproof. Now we have the requirement to really be safe we have to sanitize our cell phones almost as much as we have to sanitize our hands.
I want to credit the channel that brought this up. Naomi Sexy Cyborg Wu pointed this out 15:48 into this phone unboxing.
I don't think I've seen anyone else make that point.
So from now on and forever will wee NEED to have waterproof phones?
For that matter mice, keyboards or any other accessories we touch? At leat waterproof enough that wiping it down with 70%-90% alcohol while powered off can't possibly cause a problem even if not done carefully.
