At last I found a better use for the emergency call from lock screen (Nothing to do with emergency mode)
Initially I was trying to remove it (No luck there) as it gave a full dialer keypad and I imagined if someone found my lost phone they could call anywhere and run up a bill, but it seems it will only call a recognized emergency number even though you can type any number in. I do not know what numbers it excepts but presume they are the standard 999 or 911
I then found by using contacts you can assign existing contacts as emergency numbers. This allows you to populate the 4 icons on the front of the emergency dialer and if you have more than 4 you can also search/review the others from the dialer lower left button.
Doing this apart from it's primary use as an emergency feature also acts as a speed dial
To complete it's usefulness I changed the scrolling owner information on the lock screen to "If found please call using the emergency call button below" so apart from calling your lost phone from a friends you may also be lucky someone calls your friend/partner from your lost phone
