I have latest versions of litchi and DJI pilot loaded on my Samsung S2 tablet (Android 7) which is certified to run these apps.  None of the apps are "set as default".

When I start up my controller, the tablet provides a menu to select one of the apps, but it flashes the menu on and off so quickly that I cannot select any one of them.

I have this working on my Note 9 just fine; I can fly the drone with either app by selecting it at controller startup.  But it goes bonkers on my S2 tablet.  I've tried different cables; they all yield same symptoms.  I have USB-A connected to controller and micro USB connected to tablet.

Has anyone seen this before and do you have a suggestion?

I'll try that I guess, but at this point in the startup process neither Litchi nor Pilot have launched, so it has something to do with how the controller is interacting with Android.

Could be that the S2 is not on the supported list.
