Camera freezes and can't download apps sonce update to ios 8.4.1
My front camera started freezing when I upgraded to ios 8.4.1 the rear cam is working but when I switch it to front cam it freezes. Also, I had trouble updating and downloading apps, it doesn't update any apps so i restarted and deleted all of my apps thinking its just an error. Now I don't have any apps on my phone. And safari stops working too after a few minutes. Help
iPhone 5, iOS 8.4.1
