не работают кнопки

[original]

Hi everyone!I have a problem with the Sony Xperia z! Ceased to function keys back, home and running applications! But when unlocking the screen, the sensor reacts to the point where they are located. Same thing when you spend on the home button - is Google that is all ok! How to solve this problem? Thank you!

Не работают кнопки назад, домой и запущенные приложения на xperia z! При разблокировке экрана, сенсор реагирует на те места, где клавиши расположены, тоже самое, когда с клавиши Домой проводишь вверх - открывает меню гугл. Как решить эту проблему? Спасибо!

I don't quite understand your issue, could you elaborate?

The sensor does not respond to keystrokes back home and running programs. But responds to touch in on the screen when you unlock
