OK, update on the Huawei Mediapad M3Lite 8"
I reset to factory, allowed it to update on google and the tablet software updates (EMUI v5.1 and Android 7, build CPN-W09C100B251)
I did not install Litchi or DJI Go (for products before P4)
This process connects me every time - my P4Pro is at firmware 01.05.0600 and DJI Go4 is 4.2.8 (downloaded from GoogleAppstore)
- Switch Tablet on, go directly to Huawei Tools and optimise (clears cache,etc)
- Go into DJI Go4, wait for it to show 'Enter Device' screen
- Plug in USB lead and switch R/C on
- Switch Phantom On, wait for it to be linked to the R/C
- App message says 'Go Fly'
Thanks to Pyscho Andy for pointing me in the right direction on another thread.
Very pleased not to be giving up on this tablet, the screen is excellent/bright and it's also a superb media tablet for TVcatchup/Youtube (great sound).
As someone else said, the power button on the Mediapad M3 Lite 8 means that the tablet sits slightly over on the controller holder, although putting it centrally doesn't actually seem to activate the power button.
I've flown 4 batteries worth with this tablet, it works perfectly, very low lag, good brightness.
