Users of the HTC One M9 Developer Edition can now enjoy Android 5.1 Lollipop, which is currently rolling out to the device over the air. The update is quite hefty at 795 MB as it puts the firmware up to version 2.6.651.11 and brings in quite a few essentials for the device's overall improvement. 

It is recommended to use a Wi-Fi connection to download the big update, and the battery should at least be charged at 50 percent before pushing through with the installation in order for the switch to be nothing but buttery smooth. 

Once the new software is up and running, users will notice that call and data performance is much better in their HTC One M9 Developer Edition. In addition, the update contains tweaks that improves its battery life so users can enjoy their handset longer. 

Also included in this update are tweaks fashioned to give the users a better camera experience. These changes are expected to improve the shooter's performance both in bright and low-light conditions, something lamented by photo-loving owners of the HTC offering. 

Lastly, HTC also attempts to fine-tune the performance of the Qualcomm Snapdragon 810 processor running the device with optimizations on temperature management. Not too long ago, Qualcomm was in hot water after complaints that the powerful chipset is suffering some overheating problems. But with Android 5.1 Lollipop, HTC attempts to fix that and its software makings altogether. 

A notification about the update should have already popped up on the device but owners can always check manually by going to the handset's settings and system updates. When Android 5.1 Lollipop shows up, users can jump right in and download the new firmware.
