It works on android 4.2 operating system which is completely outdated. it has the RAM of only 1 GB which is very less for people who like to run various applications and games . In 1GB Ram you can install only selected apps and after a while it shows error of "low storage". Moreover the rear camera is another worst part of the phone .
though it is 8MP but its not satisfactory to the user . I hereby request you to not to buy this product as it will surely disappoint you.
