THE DESIGNS:
So it seems that Samsung really comes as a stunning device this time. The company proves its word by improving the new device so that it is better than Galaxy S5. Without a doubt, the metal edging and glass panels on both front and back is the thing that is emphasized by the company. The handset is fairly thin and really appealing. It really fits on the users’ hand, and best of all, S6 looks more appealing thanks to the metal and glass. Some even say it is better in the real life than in the photos.
In the opposite, the HTC One M9 has not made significant change from the previous model. However, every inch of this handset is already stylish and smart. HTC has slightly improved the back panel and edges to be more ergonomic, so that it can fit on the users’ hand.
THE DISPLAY:
Samsung Galaxy S6 comes with 5.1 in QHD Super AMOLED touch display with 577 ppi of pixel density. In the opposite, HTC has taken orthodox route. The HTC One M9 comes with 5 inch display which has 1080p full HD resolution at 440 ppi. I know that it is a bit downgrading. But 1080p will be less battery-sapping.
THE CAMERA:
HTC One M9 has opted for 20 MP primary camera. This is of course drawing attention for major phone users. The front facing 2nd camera comes with 4 Ultrapixel setup, just like the predecessor. But this time it comes with wide-angle lens for selfies. Galaxy S6 comes with 16 MP sensor on the back and 4 MP on the front. Both provides great image quality.
On paper, HTC One M9 has better quality of camera. But Samsung Galaxy S6 has better screen display with 577 ppi which means sharper image to be experienced.
Which one is better? You will be the judge.
