Well in fairness I took my bird for a test flight in my garden today, just practising figures of 8 and buzzing around to see how the phone would cope - and had no problems at all.
That was at close range, so not straining the wifi connection at all, and yes the screen did go dark for a second, but then back to normal.
I ran it long enough to get low battery warnings from the craft, so about 20 minutes. Lemme check.. 19 minutes and 30 seconds.
Being brand new it was constantly updating last night; hopefully one of the updates overcome the problematic update that caused so many problems for others?
Other than reading the horror stories of other drone owners, so far the phone seems OK. I'm preferring it to the S6, and knowing it is properly waterproof and that I can add storage space is a deffo plus. Screen seems sharper too, somehow.
OK, maybe it's an S7, not a Sh*t7 like my Sh*t6..
Eyes and fingers crossed...
