Think my point has been lost. Example. Nexus 9 is on the recommended list but some/many report that the app crashes with it.
Replies to these posts often go along the lines of , "Well my Nexus works great!" Neither have mentioned which version of Android OS they are using and the reply doesn't even mention it is the same model of Nexus! Not helpful to new starts looking to plough the minefield that is DJI Go/monitors.
Another example. Tobby... you mention your Nextbook but don't mention which Android OS is installed. Somebody reading this in several months time may buy one on your recommendation only to discover that the DJI Go app crashes with it. The difference may be that your version is using an earlier Android OS but in the time since you bought yours it now comes with a later version OS installed which doesn't work too well with the app. They're now stuck with a device until DJI make their app compatible with the later OS, if ever.
It seems from reading posts that in the USA you get 3 weeks to try it out, change your mind and take it back to the store. That doesn't happen in the UK. Once you unpack it, use it, it's yours. Getting it right first time is essential.
