Device with 480 x 800 resolution but it is mdpi

Hi all, I am using dp for all the UIs in my application. This is working fine in all type of emulator. But i am having device, in this device the resolution is 480 x 800 and the density is only 160. For this, my application designing is not good, the alignment coming different. What can i do with resolution 480 x 800 but with 160 dpi in case of dps?
