Since the launch of the HTC One M7, HTC has offered developer editions of its One flagship phones that feature unlocked bootloaders, making them easy to tweak and load custom Android ROMs onto. If you splurged on a One M9 developer edition, you’ll be pleased to learn that Android 5.1 is headed your way.
An update to Android 5.1 is now rolling out to the HTC One M9 Developer Edition, bringing with it improvements to data performance, call drops, battery life, and camera performance. The update also includes a temperature management optimization. Once you’re done updating, you should be on software version 2.6.651.11.
The update is a biggie, weighing in at 794.32MB in size, so you’re gonna want to be on Wi-Fi when you start downloading it. All of the improvements included in the update sound like solid additions, and considering that the update includes enhancements for one of the M9’s most criticized features, you One M9 Developer Edition owners should probably grab this update as soon as possible.
