Very old Blackberry phones (8800) had an in-built feature where a predefined time can be set in it to automatically shutdown and startup the phone daily. I could even define a different time for the weekends. I found this feature very useful. Unfortunately I did not find subsequently this feature in android (up to JB 4.1.2). Now I use a Lumia 520 with WP8. Is there any free addon apps available to enable such feature. If someone could suggest one, would be a great help.
