Last month my 2 year old iPad stopped functioning normally when in facebook. Went to Apple store in The Grove, L.A. The technician was awful, in rush & talking down to me, even to suggest i could change my iPad to avoid problems. How convenient! Maybe the only wise thing he said is i should close applications all the time not to interfere with what im doing. This is a hassle but i can do it. Still, when im in facebook, 85% of the time my screen goes blank if i want to post a message not even photos or make comment. Share is easier sometimes. Yet, a headache overall. I have to go to my computer or now a smart phone to use fb and i would prefer my ipad. I'm telling everyone not to trust iPads until i figure out what the problem is. I'm desperate and tempted to buy another tablet and throw my ipad away!
