Anyway, today I found a working version of Android 4.2 cool Photo Sphere feature flashable on Jelly Bean 4.1.x.
|Sample of Photo Sphere on Nexus 4 I think...|
After changing some settings in build.prop (do backups!) it decided to start. Today I had no chance to try it outdoors, but tomorrow I will give it a better try.
For now I can say that the result is pretty bad... I don't know why... As I said this needs more testing!
