Hard Coding Value of Sprite's Position

[Sparcsky]

If I hard code the value of Sprite's position, will the sprite's position change if the program is used in a different device?

I wonder if stays the same or the program will stretch the sprite depending on the size of the device.  Mostly in my code, I position all my sprite with absolute value. Is it okay to hard code the value of sprite position?

If the sprites position and size are based on percentages of the screen size, they will be scaled/stretched accordingly on different devices.

Just be careful if the devices have different aspect ratios. 4:3 / 16:9 etc
This can cause a circle to turn into an oval.
