The HTC One M9 features some of the most powerful specs currently available and in terms of hardware, it is considered among the best designed because of its metallic elements and other good materials like the sapphire covering the camera lens. The software that HTC uses in its smartphones is also considered a very good customization of the Android OS called Sense UI, and the one found on the One M9 is version 7.
One department that HTC has been focusing on but the results have not been very well received is in the camera. For the One M9, the company ditched the Ultrapixel technology in the main camera that indeed captured more light in dark scenarios, but it was considered to have a very low resolution by today's standards. The new 20-megapixel sensor included in the new phone also failed to impress, even though it can capture pictures in RAW format.
Android 5.1 is the most recent version of the operating system and it actually fixes some of the issues that were introduced with Android 5.0 Lollipop, so OEMs have been updating their devices with this new version to improve their software experience. HTC started updating the Developer Edition of the One M9 recently as well as some carriers and the update will be rolling out to the handsets locked by AT&T starting tomorrow, July 15. As with every update, some bug fixes and the correction of internal errors are expected, but HTC's Mo Versi said that the update includes that the software in the camera has been tweaked to improve its performance which could be good news to those users who expected more from the One M9 camera. Reportedly, it produces more accurate colors in extreme lighting conditions, improves the auto-exposure settings and the digital noise has been reduced.
Another important improvement that the company included in the update changelog is a better temperature management, as the Snapdragon 810 processor powering this phone is known to have some overheating issues. Data management and call reception issues have also been addressed in this update and there have been some enhancements to improve the battery life of the device.
