Agreed, without the App running, there is no way the controller would know what the RTH altitude was set at. And for that matter, if the RTH was actually activated properly or not. Frankly, here's just no way to verify anything.
If after the events documented in the log, the OP was able to still monitor the flight in some manner on the RC, that suggests this was not an abrupt catastrophic collision, at least right adjacent to the end of the log we are viewing. There is just no way to tell if it was a device issue, a RC issue, or if there was a battle going on with the OP vs the RTH. And, whether there was a collision or not. My best guess is, if indeed the OP saw 300m on the RC, which is almost 1,000 ft, it might have gone up that far, hit stronger winds, couldn't make progress home, and eventually ran out of battery and simply fell into the water.
I've had the app crash a couple of times for me mid-flight and the drone stopped, held steady, and I was able to restart and reconnect within a minute or less.
I ran into a case where GO-4 App suddenly quit communcating with Remote Controller. Remote Control was still connected to drone. Problem was restarting GO-4 App did not work. Finally got GO-4 App working again by powering Off and On both CrystalSky and Remote Controller. Took more than a few minutes to go from GO-4 App quit working to finally getting GO-4 App working with Remote Controller.
Powering Off and On the Remote Controller, did trigger drone's automatic Return to Home (at least something worked as expected). By time CrystalSky OS was ready and GO-4 App running again and connected to Remote Controller, the drone was overhead and starting to land.
?? In cases like this, it seems it is worth trying: ??
Along push on Remote Controller's RTH, to at least start drone home.
Quick stop and start of GO-4 App. If that does not work...
Follow up with a complete power Off of both SmartDevice and Remote Controller (which should start drone home).
Quick check for loose USB cable between SmartDevice and Remote Controller.
Power On of both SmartDevice and Remote Controller, followed by starting GO-4 App.
If GO-4 does reconnect, check to see drone is making progress or fighting wind...
If Fighting wind, switch to Sport mode - try to fly drone to nearest dry land, possibly at lower altitude.
