I used this phone as my personel device before 2 years after my first phone lumia 630 DS.
According to my experience if you are thinking to buy core 2 then change your thinking this is the worst device have only 4 gb internal memory and you just get 2gb to use and get full after you download 9-10 apps.
Its have a camera of 5 megapixel but not give the picture quality of 5 mp like other devices.
During call the voice is much noisy and disgusting.
Rather than you can buy other mobiles like Mi, Lenovo.
Thankyou!
