HTC Desire 820 and HTC One A9 devices have been released in the same month, but in two different years: 2014 and 2015. Both devices have good specifications that are worth mentioning and this comparison will help take the best decision in case you’re interesting in purchasing one of these phones.
The HTC Desire 820 measures 157.7×78.7×7.7mm and weights 155 grams. It has a dual tone design and a plastic body that gives it the feeling that it’s a cheap phone. On the other hand, the HTC One A9 is slimmer and lighter, as it measures 145.8×70.8×7.3mm and weights 143 grams. Its body is made of metal, being similar to the One M9, so it has two lines on the back and the rear camera is placed above the first line, in the middle. Another advantage of the A9 is the addition of a fingerprint scanner on the front panel, below the screen, which supports Android Pay, the new mobile payment system introduced in Android Marshmallow.
The HTC Desire 820 has an LCD display of 5.5-inch that supports a resolution of 1280×720 pixels at 267 ppi and it’s protected by Corning Gorilla Glass 3. The HTC One A9 comes with an AMOLED display of 5-inch that supports a higher resolution of 1920×1080 pixels at 441 ppi and it’s protected by Corning Gorilla Glass 3.
