My Layouts Aren't Scaling Properly On Low Dpi Devices

I made an android app with constrain layout, and the layout doesn't scale properly even thought I've used SP and DP as units. I double checked all values and they all have dp and s

Solution 1:

One of the issues here is that you are testing the layout on small screen sizes such as the Nexus 4 which is about 4.7 inches.

You probably did not develop the application with the initial design focused on such a small screen size.

Consider creating alternate layouts for different screen sizes.

Supporting different screen sizes would help.

Solution 2:

I have used Guideline in the center of the screen to make this go easier and it works for me, try to use this layout :
