We didn't have to change our usual or "traditional" finger positioning, meaning we were able to keep our right thumb in the bottom left corner of the pad and use our index finger to navigate. (Even if our thumb moved slightly up on the pad it still worked.) Best of all, while using that finger positioning we rarely zoomed in on something by mistake.
Just after the half-hour mark the visiting keeper did even better to get down to his left and keep out Obinna's fiercely struck right-foot shot as Birmingham's defence continued to look suspect in front of him.
