safari not working on ipad mini

Hello, I can"t seem to get Safari working on my ipad mini. The screen is unresponsive and the text input boxes cannot have any text inputted. I have gone thru the various remedys I have found in this and other forums and nothing has worked. I brought it into an Apple store for a Genius to try and remedy and the inital troubleshooting didn't work. They tried a reboot, reset, and finally a new restore and the results were all the same.....nothing. They then took a brand new iPad mini out of a sealed box and setup that one. Believe it or not, after setting it up the same problem occured on this new iPad mini! So I asked to have my original iPad back as it had a personalization etched on the back but was told it was already swapped out and they couldn't return it to me. So now I have a brand new iPad mini that exhibits the same problem of Safari not working and also the advice from the Genius that in a couple of days Apple will have an update. I haven't seen any updates as yet so I am asking anyone on this forum if they have a solution to get Safari working. By the way everything else on the unit functions, I can surf using Chrome, read emails, etc.

Thank you
