1) while on call, if you have to access any of the options like speaker, key board, new call etc, the touch hardly works, you really have to push( touch doesn’t help ) to make it work.2 ) sometimes you don’t see the symbol( green circle /red circle ) to receive the call, you just hear the ringsound but you can’t receive the call , which I really hate. You need to reboot again.3) photo quality is really poor and processing is very bad and gallery also process very slowly . If you really like my review plz comment and like
