Not only are there pop-up ads but the ones that pop up are inappropriate and one said "What has been seen cant be unseen." and had what looked like a woman who was nude at the waist being groped by another woman. My kids use my phone regardless of what the picture was really showing it is completely inappropriate. (Im assuming it was really a poorly staged picture and not really a partially nude woman.)
