Android Question Bluetooth App Locking

[codie01]

Good Day all,

For the past two years I have been using an app to control water levels with no issues. Yesterday I upgraded my android device to a Samsung note. I can send data to my Arduino H6, however when I receive data back the app locks.

Thanks All

The following is my code:

#Region Module Attributes
    #FullScreen: False
    #IncludeTitle: True
    #ApplicationLabel: greenHAUS
    #VersionCode: 1
    #VersionName: 1
    #SupportedOrientations: portrait
#End Region
