[Android] Can't change selection in QComboBox with touch input

QComboBox on Android does not allow me to change selection with touch input. S-Pen input works. 

To reproduce, run "Spinboxes" example and try to change format string for the meeting date and time using finger.

Expected:
Can select another format

Observed

Can't select another format.

A similar problem is visible with the audioutput multimedia example, where I can't change audio output using finger, only with S-pen.
