Ok, so I have now completed several(>10) flights with Client V1.2.9, Flying Control V1.1.2, ESC V1.0.3, Camera V2.0.11(F) European version using a Samsung Galaxy S6 Edge Nougat and my observations are as follows:-
1.) All flight modes work as expected including 'Follow Me'. Not tried FPV as I don't have a controller.
2.) The indoor/outdoor WiFi option I had previously in V1.1.9 has gone.
3.) The option (gear icon) to select the exposure compensation is still greyed out and unavailable.
4.) After switch on, the drone takes much longer for the WiFi to appear (a couple of minutes) whereas it was at least three times faster before. On the plus side it will always be found - eventually!!
6.) In some flight modes the app. crashes and disappears. Running it again so allows you to pick up where you left off whilst the drone hovers patiently.
6.) Finally, and most worryingly, the WiFi can be lost at any time during the flight. The first couple of times were near the edge of its range so I wasn't too worried. The most recent time, the drone was only a couple of metres from me and just out of reach. The battery was around 80%. As the WiFi is sooo slooow now to find, the drone got fed up/worried and initiated its Return To Home sequence by rising up to my preset height of 10m, flying back over to the launch point and then waiting at full height (10m), presumably until, I either re-connected or the battery was low enough to initiate an auto land.
However, as I waited helplessly for the it to appear in the WiFi list, the drone started to drift (there was little wind so I don't know why and drifting is very unusual in my experience) and drifted about 3 metres right into a tree. Needless to say just as I reconnected, the prop. protectors were overwhelmed, the motor(s) stalled and it crashed down to the ground breaking three protectors but otherwise OK.
In conclusion, the loss of the WiFi plus the large amount of time to re-connect (and the weird drift) makes this drone with this software version untrustworthy except in large open spaces with nothing bad underneath to land on. Unless another new version comes along soon, I will probably be reverting back to an earlier version. Also, the Play Store changelog of 'Fixed some bugs' is woefully inadequate when talking about such a complex bit of machinery. Why can't Yuneec let us know what they have done between each version so we can make more informed decisions about what we fly?
