Samsung S3 to Sony KDL-40NX803
Confused: you say phones with "Allsharecast" will work with "Miracast" yet you contradict that by saying it only works on Android 4.2.1 and above.
My S3 (GT i9305) Lte has "Allsharecast" so it should work...Yes? and yet it is running Android 4.1.2 Jellybean.....which is below your stated "Android 4.2.1" .....so it won't work?......Confused!
If you can clarify that with a definite "Yes", the next question is will it work with my Sony KDL-40NX803
