HTC One features an "ultrapixel" rear camera for better image and video capturing. Unfortunately, the camera technology on HTC One is plagued with several issues and few of them are just too severe to endure. Here are the top common problems and quick fixes on HTC One camera.

Blue/Purple/Red Noise

Some users reported that blue, purple or red noise is noticeable on HTC One camera shooting under low-light conditions.

Solutions:

1. Lower down the ISO configuration to reduce camera's sensitivity to light and reduces noise or grain.

2. If manual settings inside the camera don't help, have it replaced to your retailer. It may have been a hardware issue.

Camera Not Loading

In case the camera app fails to load or crashes, you may simply clear the data or cache of the app from the Settings menu.

Solutions:

1. Go to 'Settings > Applications > Camera > Clear Data/Cache.'

2. If clearing the cache doesn't fix the problem, force close the camera app then reboot your smartphone.

3. If all solutions failed, a software update from HTC may have the bug fix.

No HDR Mode

If you have updated your HTC One which removed the High Dynamic Range or HDR mode, recheck for another software release that brings back HDR mode. Go to "Settings > About phone > Software updates > Check now."

Purple Haze

Purple Haze bug on HTC One is one of the biggest camera problems ever known and only expected to change after Android 4.3 Jelly Bean reached the device. Constantly check for an update on your phone which may contain the solution regarding Purple Haze issue or have the device replaced from a service centre.

Not Enough Memory

Sometimes, the camera app won't load due to memory problems which can be fixed easily.

Solutions:

1. Double tap the "home" key then slide tiles off the screen to close apps running on the background.

2. Another solution is to reboot the smartphone to free memory on the RAM.

3. Use the "back" key when leaving apps instead of the "home" button to prevent running tasks clogging on the RAM.
