Agreed, the white tile neither contrasts nor blends well.

that will leave our bottom tile with only 1 inch is there any way to fix it or any alternative to this issue

What "bottom tile"? Please clarify.

Do you mean the size of the subways that you will use to replace the granite are not the same size as the granite back splash? If so, you could lay them the other direction; up and down, as opposed to whatever pattern you have now. One row like that will look OK. How about a close up picture of what you have now?

I don't care for the look of the white subway tiles with your granite but I don't live in your house so my opinion on that really doesn't matter. A subway that blends with your granite would look very nice and you wouldn't have to take the granite off. Either way, your wall behind either/both will be damaged.

If you are removing the granite backsplash and replacing it with the white subway, use a 1" (or so) accent line at the bottom of the current white tile.

Handymac's idea is good

Leave the granite and remove the tile... two problems solved
