I have used this phone since last year and its a kind of best experience for me.
Canvas spark is my first smartphone and it changed everything for me.
It takes very nice pictures which is sometimes much better than phones of bigger companies.
On a decent plaing it never hangs and it do only for what it is produced.
It can be best ever a start up or your smartphone journey.
And the performance is good, but the main attraction is the camera which is just fab. And performance also.
This mobile is a very good option for the mid range buiers of 5k to 7k.
Hope this review is going to help u.
