Using the app with most Huawei, once the drone is connected and flying the screen turn off after few seconds. (the time out set of the phone I suppose).
With IPhone Freeflight Mini, works well and this issue does not occur
Downloaded few hours ago, for my Huawei P Smart Plus.
Maybe the screen time out issue has been solved.
I connected my mambo and after flying 5m the display remained on.
I only had to set my flypad commands
