Htc haven't launched this handset in every country. Htc claims that this is the successor of htc m9.
Coming to processing htc haunt some extraordinary job because almost all high end smartphone are faster than this.
Coming to camera it is above average when we compare it with high end smartphones Camera.Although it can record at 4K but the stabalization is not that helpful.
Overall image quality is not that appreciable.Htc sense comes with some pre loaded bloatware.The GPU performance of this device is satisfactory and build quality is good.Look for one plus 3.
