Do you use a screen saver? I have an Ivisible Shield on my iP4 and I have to push a little harder to get my slide-to-open function to work. Outside of that, I can't offer you much help.
i just recently had the same problem with mine. I was in the grocery store at the time so i just put my phone in my pocket after it malfunctioned. By the time i got home and remembered my phone was acting crazy i went to check it and everything was acting normally. Very strange glitch. I closed all my apps and turned it off and back on and havent had any problems since...hoping it was just a one time thing.
I will try this again, being as I do not see my last post.
I always post a thank you to all that help with my posts. On this one, so far so good, it has not locked me out yet.
Opps, I did not look at the pages of this post, we are on page three, I went back to page 2 and found more posts on the subject. Can't believe it generated that much interest.
I took my phone out of the holder my wife gave me. It was a Blackberry holder, it worked fine. I think the magnet on the flap might have been the problem, so far so good.
