Micromax Canvas 6 Pro E484

The phone is not up to the mark as I would say that it has following loop holes

1. the os version is outdated which is not good as compared wit other phones

   
   




2. it comes with non removable battery which is again not a good feature

   
   




3. it is available in single color varient which is black but still you need some extra class it is hence not good to own this phone

   
   




4. the phone missed finger phone sensor which is not durable is it?
