Back when we reviewed the HTC One, we were quite pleased with the low-light performance of the camera. However, the daylight performance wasn't quite as good, thanks to the excessive noise in the images.
The issue, of course, was not with the hardware but with the software on the phone. Thankfully, HTC has chosen to fix it in the latest software update, as was discovered by the folks over at HardwareZone.com.
According to their updated review, the HTC One running the newer version of the software provided significantly sharper images than the previous one, especially around the edges. You can see the difference in the image below (more are in the source link).
However, there was one issue that was noticed, and that was the quality of the images at ISO800, which were mysteriously softer and noisier than the images at ISO400 and ISO1600.
