So by now I guess this isn't just a small problem because I met people with the same problem. Even though they are not here complainig.
Although a really annoying problem it can be surpressed with just a little touch on the notification bar/screen whatever. But it's not supposed to do that.
By my "testing" so far, it happens only in apple apps like messages, email, settings etc.
After it happens the third party apps do it to, but so far they are never the failure origin.
Even if you don't do anything about it, please give me and the others the chance to return my ipad to the less "cool" but more stable version 7.1.2.
Please
