"It's second major firmware update bringing the phone up to 1.40.401.5 in Europe. The over-the-air update aims to address some longstanding issues with the device, with improvements to the camera, battery life and tweaks to the way the phone charges. Camera optimizations are a big focus of the latest M9 firmware update.
Today's M9 update brings three major camera tweaks, according to the manufacturer. First, improved auto-exposure so images look less washed-out in brighter conditions. Second, changes to image processing in low light to reduce noise and blur, for greater clarity and improved detail. And finally, HTC has worked to reduce green and yellow hue effects in "extreme lighting conditions," so colors should appear more realistic...."
I Would LOVE to hear how things are after people get this update.... I'm in the same boat, ready for an upgrade and am a big HTC fan. Really love my M7 but I do take a ton of pictures with my phone it that was a weak part of that phone - I expect more/better in my next phone.
