Hi. Long story short, my iPad is acting up and sometimes it moves on its own. I want to read eBooks on it, but it gets difficult when it starts randomly changing pages, zooming in and out, etc. Is there a way to lock my iPad in the same way you could lock your iPod classic, iPod nano and iPod shuffle? That would prevent it from acting up while I'm reading a page. When I want to change pages, I would simply unlock, change page, then lock it again. Is there a way to do so with or without an application? Thank you, Sophia K.
