I've got two kinds of UMI models but not an Iron. The gesture control is placed in the Settings menu at both of my phones. Iron users already reported that, the gesture control is available and works. Look into the Display settings, maybe you can find it there.
Hello and thanks for your response, the changes are randomly and without a "warning" - volume bar flashing on the screen or something else. Strange "problem".
