Hi . First of all,hello everyone.im Ricardo. Im new in the forum.im from portugal and i have my ipad mini for almost 2 years.always working fine since 2 days ago, it started to maximize and minimize all by himself. I went to an apple store and they advised me to restore my ipad to default configuration. i did and nothing,problem remains. i made a small movie with my cell phone so you can understand better the problem. has anyone had similar problem? cheers.
