Layout displayed differently on different devices at the same resolution screen

Question

Problem: layout displayed differently on different devices at the same resolution screen. I tested it on Samsung Galaxy S4 (1080x1920) and on LG G2 (1080x1920). It the same resolution, so why layout is displayed differently on each device ?

I have all in layout folder and not have another layouts for other resolutions.

Here are screens:

• Samsung Galaxy S4

• LG G2

Answer 1

The phones do have the same resolution, however, the window height is different because LG G2 has navigation keys on the screen.
