Q: IOS 9.0.2 update problem on Ipad

I updated IOS 9.0.2 on my Ipnone 5s and it worked perfectly and I liked it. So I said its a nice software and lets update it on my Ipad Air. I updated IOS and now it is disastrous. At the beginning it rebooted hardly, it took so long, but I said its fine. Afterwards I went on to enjoy the new software but it was not possible because it does not working at all. The screen freezes all the time. I searched through the Apple Support to see whether there is a solution for that but some have said that you should force restart your Ipad. I did that and surprisingly it started working but after a few hours I was not using it, the problem started all over again. From the day I have updated IOS to 9.0.2 its like I have lost my Ipad. What do I do with it? its a disaster!
