I'm not really sure what you mean, can you please elaborate?

Кнопки располагаются выше чем должны быть, что существенно затрудняет работу (нажатие элементов, которые находятся внизу экрана) на данном телефоне. Возможно это исправить самостоятельно?

Buttons are placed higher than should be, making it difficult to work (pressing elements that are at the bottom of the screen) on your phone. Maybe fix it yourself?

Do you have a different home launcher or any intrusive app (such as roating/landscape app)?

It's a quite strange situation. So on your phone there are 2 rows of home, menu and back button?  Are you sure its a xperia J model?

[Step_ik1]

нет. один ряд кнопок. он распологается выше. я указал на фото.

no. one row of buttons. it is placed above. I pointed to the picture.

[franzu84]

Is it on the touchscreen or on the body of the phone?
