Pvz 2 broken touchscreen

For some reason, when playing pvz 2 the touchscreen breaks when playing a level.

There will be random spots I can't touch. If I try to place something and hover over those spots it forces me to plant. The same thing with shovel and plant food.

It's very annoying. Sometimes it covers a hole chunk of my screen and I have no way of finding where the spots are unless I want to risk it forcing me to plant.when it covers a part of my screen and I can't place it, if I swipe fast enough it lets me move past. Until there are more hidden spots.

It only happens to me when playing this. Please help
