With some file explorer (Es Explorer, Root Explorer, etc.) open the build.prop file located at: /system/build.prop Within this file, locate the following line: ro.sf.lcd_density=240
Value "240" is the factory original. We can change this value to we change the density of the screen. The lower the value, the greater the density for Change any value between 160 and 240 (Tested with 160 and 192) After change this line, below the line "#ADDITIONAL_BUILD_PROPERTIES" has another line equal to modified up there: ro.sf.lcd_density =240
We will comment this line, simply by placing a # at the beginning of it (this line should originally be deleted, but if you want to go back to the original DPI, should resume this line. Leaving it commented, is virtually a “backup" her. If you just uncomment it)
Save the file.
Delete the file generated by the system, build.prop.bak
Reboot the phone.
