i bought this phone on 1st day of sale .

1. there were no good case for this model because of its rotating camera. so i bought a 2k rhinoshield case.
2. in starting call quality was pathetic ,after 2,3 months it got better but not like other phones which are way cheaper than this.
3. at the end of 1 year of purchase ,it stated freezing.
4. and yesterday , to be specific after 1 year and 1month after date of purchase it just got dead.
