The advertised benefit is that you simply point the drone at the place you want to be. Tap where you want it to go. It flies straight there but uses its sensors to avoid or go around obstacles in its way. Mine does this to obstacles in front but seems to do the opposite at the sides. It heads for rather than avoids. Personally I dont really have that much use for Tap Fly but if I find a use for it in the future? Not only that if I ever sell it later I would like all the functions to work as they should. I would never sell anything that was broken. After all these are not cheap toys and 'you get what you pay for'. If this is malfunctioning when new what other things might I discover down the line? If I decide now 'who needs side sensors anyway or the other new bits' I could have just stuck with or go out and buy the P3P which worked really well for me. It is nice having the better camera and range but if I buy something I would like it to work as it should.
The main problem seems to be the Go App. Unfortunately, according to DJI Techs, you cannot replace it on the Plus version.
