GPS altitude is not very accurate, i have seen estimations of about 50
meters (160 ft) errors. The more satellites the better although.
A good rule of thumb is that if your feed are wet, it is very hard to
breath and your phone and gps ceases to work you might be below the sea
There are however some dry places below the sea level: death Walley in
the us and part of Netherlands.
You can still escape from the Gates of hell: Use Linux!
