Nexus 4' camera quality is not that good, but photo sphere taking software is really good! The difference between this one from Note III and one from Nexus 4 would be pretty noticeable in favor of the N4. Can someone confirm this?
I haven't tried this on my Note 3. The artifacts of improper merging are OK if you aren't doing this to sell a house or some other professional purpose. So pix of a family picnic in a pretty place seem like a good use. Shared to allow others to see the surroundings.
