I have a Samsung Galaxy Note 10.1 running Android 4.1.2 with Flightradar24 pro version 3.1.7 and have two problems.

1. For at least a couple of weeks I have not been getting any 7600 or 7700 squawks.

2. The AR has never identified correctly what I have in view. In an earlier post mention was made that there would be a 7/8 second delay if the a/c was too close. Can someone please quantify "close". I estimate the a/c I am trying to ID are approx 40 kms away.

Any help with the above will just make a great app even greater! Thanks in advance.
