HTC releases camera app fix after the T-Mobile HTC One OTA update removed HDR functionality - HTC Source
The latest software update for the T-Mobile HTC One may have fixed LTE connectivity issues and improved handset performance, but HTC somehow managed to remove the HDR functionality from the camera app. We’re not exactly sure how it happened, but HTC has responded quickly by releasing a camera update for the device which brings back the lost functionality.
HTC needs to do little bit of work to ensure a higher standard in quality control with its software updates, but we applaud them for an extremely quick two day turnaround time on the fix. Now that we have that issue out of the way, we’re hoping HTC and T-mobile can get around to releasing the Android 4.2.2 update for the HTC One.
If you’ve already downloaded the latest OTA update for your T-Mobile HTC One, you can try pinging HTC’s update servers to receive the Camera app update by going to Settings > About > Software Updates > Check now. If the update if not available, you may have to wait patiently to receive an update notification on your device.
