please help. my ipad icons have shrunck and some iocns like safari and mail are completely missing. i have to search to find them, which made me realise that the keyboad has also shrunk. the screen is also flickering especially when i try to use the contacts icon or the settings icon. i have tried switching the ipad on and off several time. i have tried to restore from the back up and nothing. i also tried to update and then restore. a messages says that "the ipad could not be restored as the device isnt eligible for the requested build" i not sure what this means. i live in malawi - africa so have no apple store outlet to contact for help. this is the only forum. im desperate and really worried. your opinions and suggestions would be much appreciated.
