Ipad Suddenly stuck in zoom

The problem started 2 days before. While ipad was charging overnight ( with ios 7.1.2 at that moment ) when i check it at the morning the screen was zoomed 50%...I thought a reset would fix the situation and to my surprise i saw half the apple in the boot screen...Nothing changed...I search online for the problem and these are the steps that i have followed..

1. Accessibility-zoom=off. Nothing happened still zoomed in

2. Tap three times with all the possible combinations( home button or on the whole surface of ipad), still zoomed in

3. Hard reset again.... Zoomed in

4. Update ipad to 8.1.2 still nothing. Zoomed in

5. Steps 1-3 again in new firmware still zoomed in.

So i don't know if there is something else i can do.....

All these manipulations were made in a zoomed ipad and every time i have got to turning it around so that i could find a sweet spot where i could select an option in menus....Trust me a very annoying and difficult situation....

Any advice would be appreciated....

Thanks....
