The HTC One M9 in Europe is receiving 1.40.401.5 firmware update. This brings huge improvements to the camera and phone operation. If you have a HTC One M9, it is worth updating to this asap.
The camera receives 3 improvements – improved auto-exposure so images look less washed-out in brighter conditions. better image processing in low light to reduce noise and blur, for greater clarity and improved detail and a reduction in green and yellow hue effects appearing in extreme lighting conditions so colours should appear more realistic.
The update also reduces power consumption with Facebook and YouTube, and tweaks quick charging capabilities to reduce heat output while charging. I personally thought the phone got too hot to hold whilst charging and using it for even basics tasks.
If you have updated your One M9, please let everyone know if you are seeing all the above improvements.
