My wife's ipad mini is about 2 years old - for a while now she has been finding it difficult to use. Sometimes she turns it on and its fine, other times (becoming more frequent) the screen starts jumping about and loading apps she has not clicked on. Also she may be playing music (her beloved Barry Manilow) and it jumps to a different album. Before we take it to someone who can repair these and the expense that will be, I wonder if there may be some easy solution. Could someone please advise, will be very grateful as will my wife. Thank you.
