184 is recommended lowest. i myself just use 3 screens, and one of them is filled with Jorte calender (really good free adfree calender from market) And still running at 240 dpi
1. What is the purpose of changing the DPI settings? Making the picture smaller/larger and that's it?
2. Is there a way to keep settings in the build prop file. I added a line, but after the restart, the line was gone
