ok... ytd i put my K550i on a table and didn't know there was a magnet screw driver, when i came back i found out that the screw driver with the magnet part was sticking to my phone's speacker. And now the middle key has turned into another camera shortcut and the down key turned into the shut down menu... I've tried updating my phone... but nothing worked... but after a few minutes.. the keys were back to normal BUT i need to press really hard on the up navigator key to work.. anyone know how to fix it? pls reply thx!
