If it's Android specific you know the answer.
I could look for an older 2nd hand android tablet or switch to Apple, but in the meantime PAW is no longer compatible with new Android tablets, which seems less than ideal.
I think you're looking at a miniscule sample of the Android user base.
Where the aircraft is flying with some form of internet access for the PAW, the Android device will be more likely to stay connected because there is Internet access.
One solution is to get a simple mobile broadband router or MiFi and to connect the PAW to that wirelessly via the iGrid dongle.
Then any device connected to the PAW with the PAW router function enabled sees the Internet and has no reason to move or drop the connection.
Have you thought of trying this?
It is my own set up and comes with other benefits, like the licence auto updating without retyping the new key, supplementary traffic and rainfall radar, and so on.
