Can I fix my touchscreen or does it need an IOS fix?

Since the last IOS update my touchscreen has gone wonky. There are several applications where the keyboard suddenly changes from one language to another, the back key doesn't erase letters but produces a random selection of them strung together and predictive text no longer works either. While typing random letters appear in the middle of words without me typing them. It is so bad that I had to change to my computer to write this.

There are also some games where the touch screen control is gone. For example in Hayday swiping motions do not 'connect' with the items and normal actions on the screen but produce random effects in other parts of the screen.

The screen 'jumps' as well, as if I was pinching something open and close when I am only using one finger.

In addition, when I open the device my usual start screen is gone. It tells me to press home when there is no such app on the screen. To gain access I have to open and close a random app to be able to see the others. Completely unusable.

Since it only started immediately after the IOS update with all the new Home stuff - that frankly I do not need or want - things have just gone from weird to weirder. Oh yes, half the time the games cannot connect to Game Center which means that I cannot safe my progress and hence cannot just unintall and reinstall.

A major glitch this IOS.

Anybody have any idea if this is affecting more people and if yes, when it will be fixed?
