Haven't purchased the software yet. Purchased a new Samsung S10 with android 11 installed (Perfect, just what Marshall has verified). I went to T-Mobile and asked if I could stop the phone from updating to Android 12 by itself. He assured me it could not without my permission and my intervention. That night the phone updated to Android 12, by itself. The Marshall Android software is Beta software which is why they are not certain of it performance. I understand and accept that. Not to excited about the guy at T-Mobile though.
I will be using this on a Red Tailed Hawk so for the time being I just need to know where the bird is. Not its speed or altitude. What issue are you having.Just aspects of performance or not working at all.
