How to use.
Open application and select your DPI from DPI picker. (scroll finger across the box)
Selct 'SET DPI'
Done.Sometimes setting certain DPI may makes many applications non usable. And when your launcher / keyboard ecomes unusable then it will be difficult to reset. So when you testing DPI it's recommended to select "Auto Reser' option ON. This will reset DPI to normal on reboot in case device becomes unusable to perform action.Also to note that this application won't make any application multi DPI, this will depends on your ROM.
