OnePlus is finally rolling out its Android 4.4.4 KitKat upgrade for the One. Originally expected in July, the new firmware delivers updated apps, a whole host of welcome bug fixes, and a number of new features — including a Clear Image camera mode that provides super high-resolution photos.

This is the One’s first major software update, and it’s one users have been very much looking forward to — mostly due to the bug fixes, which address some pretty pesky problems.

With this update, the “Ok Google” voice command should finally work reliably; track information on the lock screen should update properly when listening to music; and the battery percentage should now update when using custom lock screens. Vibration should also work as expected during Quiet Hours, the “O” lock screen gesture for the camera has also been fixed, and wallpapers should now apply in fullscreen.

Other fixes include:

• Microphone volume for all formats in the Voice Recorder app
• Viber calls not working
• PicasaSync

OnePlus has made the One’s capacitive touch button’s brighter, added support for capacitive touch buttons in recovery mode, and improved overall stability. This update’s most notable addition, however, is Clear Image, a new camera mode that lets users take even sharper photos.

“Clear Image is your camera on clarity steroids,” OnePlus says on its blog. “10 individual photos are stitched together for a final super high-res photo when you snap a shot. Through interlacing and compression algorithms, the camera improves clarity, reduces noise in low light, and adds detail that other cameras cannot.”

This update is rolling out now over-the-air, so if you haven’t already received it, visit the Software Updates section inside your Settings app and have your handset search for it.
