Hi there. Just updated mine.
At 50% the update failed and the P3S starded to make an auful (lowd) beep noise.
I thohgt everything was lost.
Turned off everything and repeated the update process (with the auful beep and the normal beep at the same time).
After 20 minutes, update was successfull.
Had to repair RC, did a IMU & compass calibration and hit the sky.
I can confirm than in my case I also observed an increase on range.
I`ve also notice an increase on GPS signal (before I could roughly get 6 sat locked, now I can get 9 sat easily).
Got 200 mts with good signal on a very wifi-crouded air space.
When I went cross some trees, i finally got signal lost.
The RTH function kicked on and landed safetly on my house.
Regads.
