Official Android 4.4.2 KitKat arrived on HTC One during February via Over-the-Air update to bring various changes such as Cloud Printing service, security patches and new HTC Sense UI version. Unfortunately, the major "Purple Camera Hue" remains on the device from Android 4.3 Jelly Bean.
Purple Camera Hue Persists
HTC One's unusual and major bug reported on various Web sites including XDA developers is the "Purple Camera Hue" which is described as coloured tint such as blue, purple or red on captured images.
Owners struggling with the issue asked for software troubleshooting or other tweaks to overcome the problem in order to take advantage of the 'ultrapixel' camera on HTC One. Some troubleshooting strategy include manually modifying the saturation and contrast or changing the ISO mode.
HTC was believed capable of fixing the camera problem via Android 4.3 Jelly Bean update, however, those users who have upgraded the software of HTC One remains unsatisfied. Somehow, it is the camera lens to be blamed with the reoccurring camera hue.
Android 4.4.2 KitKat Failure to Fix
Many reconsidered that HTC may be able to resolve the undying camera hue by sending out the official Android KitKat firmware. Surprisingly, some users ailing with problem still see the purple camera hue on their smartphone.
Some owners commented on the latest software upgrade news on Soyacincau.com and revealed that HTC failed to fix the problem on Android 4.4.2 KitKat update. One comment even described that the purple hue has gotten worse than in Android 4.3 Jelly Bean.
Permanent Fix on Purple Camera Hue
Android 4.4.2 KitKat failed to resolve the purple camera hue on the HTC One even if updated to Android 4.3 prior to KitKat. According to users who found a way to fix the issue, purple camera hue is caused by the defected camera hardware component rather than a software bug. And in case you have the same problem, here is what you need to do.
Users with access to service centres or stores:
1. Keep the device on Android 4.3 Jelly Bean firmware if you haven't updated to Android 4.4.2 KitKat. Don't need to revert if you already did.
2. Check the warranty of your smartphone, box, receipt and all accessories. You need to bring every important part of the purchase.
3. Visit the service centre of HTC or the retailer where you've purchase the device.
4. Make sure you report the purple camera hue on the warranty to get a replacement.
Users without instant access to stores:
In case you are not capable of visiting the store or really far from it, simple tweaks below will help you resolve the problem temporarily. You may combine them to achieve the best capture mode.
1. Set saturation and exposure level to -1 or -0.5.
2. Combine set levels of saturation -2 and contrast +2.
3. Make purple to white by setting saturation -2 and contrast 0.
4. Don't set the saturation +2 to avoid red hue.
5. Set ISO level to 100 and saturation to -2.
6. Use camera when it's cooler since high temperature may generate red or purple hue.
