In Welcome activity, press "back" key will exit and go back to original activity about mylockforandroid HOT 2 CLOSED

The instructions on the screen tell you to press back to resume last activity -
the ability to lock the back key exists but not the home key. However, most 
user like 
having the option to resume the last screen because the app will create this 
screen 
every time standby happens. Back will function as if user opened a new screen 
from 
notification tray and wished to return to their last screen in the stack. If 
this 
option did not exist the only way to get out would be to use the home key, 
making the 
process of navigating back to what they were last doing more obtuse.

In other words, the issue is deemed invalid because it is a design choice so 
that on 
the screen we do not have to waste space to include a button the kills the 
window. We 
feel the back button is fine for this function. We wish the stock lockscreen 
gave you 
the option to disable the sliders and add widgets, utilizing the back key as 
the unlock 
key.
