Nexus 7 weird issue after 4.4.3 upgrade

[AC Question]

Hi All
Please help....My wife has Nexus 7 and while we were on holiday in Greece and on the hotel's wifi she decided to upgrade to 4.4.3.
However once the upgrade had finished the screen colours look like they are being viewed with sunglasses on..Also when using the keyboard to type anything second row of letters is hidden behind the top row..its really weird and very frustrating...I really don't know what to do ...any ideas anyone ?

thanks in advance
