Different models have different screens, different colour bezels and buttons.

But the sure ways to find your model number are to remove the battery and look at the very small print under the battery,
OR,
boot into bootloader by powering off your phone then hold the VOLUME DOWN button while you press POWER. Your phone should boot to a multicoloured screen with some text and the top line of text should say "RHODxxx". That is your model.
