Forgot to improve the camera
When it was launched last year, the HTC One M8 was regarded as a complete package but its only drawback was its average camera. Apparently, the HTC One M9 went through the same development too. It underwent a major upgrading but somehow forgot to improve the camera.
The HTC One M9 features the Snapdragon 810 octa-core processor and has the distinctive top-and-tail stereo front speakers that deliver superb sound quality for a smartphone, due to its BoomSound. The device also supports Dolby Audio too. The battery life of the HTC One M9 is similar to the HTC One M8 although it drains rather quickly if users browse the web.
It also features a 20-megapixel image sensor manufactured by Toshiba but does not offer class-leading dynamic range. And dynamic range is not something that a software update may be able to fix since it is more of a hardware issue. It is not clear how the software update will improve the camera of the HTC One M9 but it is unlikely that it would make groundbreaking improvements to it.
