You can manually edit the /system/
build.prop file to change your
device’s resolution. To switch from
QHD to FHD, adjust the ro.sf.lcd_
density line to 480 and the width
and height lines to 1080 and 1920
respectively. Be warned, change the
build.prop with care!

If manually editing the build.prop file
is too daunting – and be aware, an
error in the file can easily cause
your device to boot loop – there are
a number of build.prop editors
available on the Google Play store.
Build Prop Editor (Free) by JRummy
works well for a safer modification.

Use a build.prop
editor to be sure

Resolution Changer Pro, also free
on the Play store, is an app that is
dedicated to changing your display’s
resolution. Remember when you
make modifications that the width
and height values are based on a
portrait orientation for phones and
landscape orientation for tablets.

If you have a Samsung device and
you only wish to modify your device
resolution for gaming, then you are
in luck! Samsung has recently
released Game Tuner via the Play
store to permit custom resolution
and FPS settings on either a
universal or a per-game basis.

After you have changed your
resolution, it’s worth investigating
the effects of just changing the
density. A higher density shows
more data on the screen, but be
aware, not all apps will perform
correctly at custom densities so
trial and error may be needed!

After you have applied your updates
and rebooted (changes don’t take
effect immediately), everything will
probably look the same! To be sure
your changes have been applied,
use an app such as Screen
Resolution & Specs by K. Lee, free
from the Play store.

Another interesting step to take is
to use benchmarking tools to see
what level of performance
improvement is being experienced.
Since lowering the resolution will
decrease the load on the graphics
processor, GFXBench is a good tool
to use to measure changes.

Although build.prop changes are
only applied after boot, some tools
use Android shell commands to
apply changes with immediate
effect, which is ideal for testing.
NOMone Resolution Changer from
the Play store is an ideal app for
experimenting with densities.
