Unfortunately the 4.1.22 does nothing to fix the otg telemetry issue so looks like it's now gone for good seriously limiting the use of the spark and as I'm within the time limit set by the place I purchased it from I will be returning the spark as not fit for the purpose it's sold for, it can not reach anywhere near the distance advertised in the UK as WiFi is not useable over 30 meters away without the video feed becoming disconnected. It's such a shame I really liked the drone but over £550 for what is no more use than a £100 drone from gearbest is a joke.
