I have some feedback on the new built-in GPS Averaging feature in beta 3.39.4.2:
First, the really obvious glitch. My true coordinates are N53 W113, but the averaging screen shows S113 E053! N/S are switched, E/W are switched, and even the order between the two numbers is switched. Oh, and there's a leading zero that's not needed. Also, it shows a distance of almost 14000km, which I assume is half the circumference of the earth.
But more importantly, there's an issue that's been around for years. Once you tap Confirm, you're back at the point's Basic Info screen, with correct coordinates. But the altitude is not what you just measured. It appears to be SRTM altitude, but who wants that number when you've just measured a more accurate one with GPS? And "Get" is ambiguous; what does it do? (My best guess is, fetches SRTM altitude again, if not already known.)
Occasionally I like to measure peak altitudes for updating OSM, but have to remember to record the altitude separately because I can't trust the built-in field. (Can't trust because it's ambiguous, and the number is different than I expected to see.)
Also, the choice of "GPS Averaging" as the name could cause confusion, as it's the same as the name of an external app doing the same function. Since "My Location" and "GPS Averaging" are similar concepts, maybe you want different names such "My Location - Quick" and "My Location - Averaged"?
And one time only (first time), when I tapped "Get", the app disappeared. A few times after that, no problem.
PS, it's a great solution to the problem of the external app having become malware. Though for my own use, I managed to find an old good copy.
