I just downloaded LocalCast from the Play Store and initial testing shows a lot of promise. I was able to put my own photos and videos on the TV from my Galaxy S4. Some of the higher resolution images and videos were really slow to load, and stuttered. The still image quality was good. The video image quality looked a little over driven.One high res video wouldn't play at all, but overall it looks extremely promising. I just noticed an upgrade has been released, but I haven't downloaded it yet. I'll post more when I try it out.
