Android Question Blinking form

[AHilberink]

Hi,

I have a strange behaviour:
I have a form with some edittext, spinner, label and button on it. I disabled the screensaver using:

Private ScreenSaver As PhoneWakeState
ScreenSaver.KeepAlive(True)

but my screen is blinking (short to black and back) from time to time. This happens on 2 other tablets.
All the same Samsung Galaxy TAB3. No lost of input, but annoying.

Could this be something of the app or of the device?

Best regards,
André
