Hi sagars,

I'm not sure I understand your question so I apologise if what I'm about to say isn't related to it.
I assume you are talking about "Back", the right softkey (which is sometimes "Exit"). If so, the only way I can think of is returning the application to its previous state. For example:

import appuifw, graphics
#We create the initial state of the application:
def UI1():
   appuifw.app.title=u'Name'
   
   bg=graphics.Image.new((240,240))
   def h(rect):canvas.blit(bg)
   canvas=appuifw.Canvas(event_callback=None, redraw_callback=h)
   appuifw.app.body=canvas

#Now we modify this state:

appuifw.app.title=u'New name'

bg.text((20,20), u"text")

#Now we assign the UI1 function to the right softkey, so that it will "take us back"
appuifw.app.exit_key_handler=UI1
