To fix this problem the XDA member NODO-GT created the HQ camera mod for ICS on HTC Sensation. This mode unleashes the true power that holds the camera of this smartphone. It gives the ability to record uncompressed videos and audio, as well as to store uncompressed photos.
The features of the HQ camera mod include 1080p video recording in impressive 20mbps, increased video recording quality, zero compression on JPEG images and videos, Increased size cap of images, improved quality of images and even experimental 1250 ISO mode.
