+Android Screen Density
+======================

+
+Recently a Droid X owner I know showed me a software that can change the screen
+density on Android phones (I can't remember if it was a part of his rom or
+not). I thought it was cool, so I set out to find a way to manually change
+screen density without installing any additional software since I try to run as
+minimalistic an install on my phone as possible (my fellow Evo users out there,
+you know why).
+
+Just before we start things off here, I'd like to put a disclaimer on this one.
+You likely won't brick your phone (you'd have to try really hard or have really
+bad luck), but you can mess it up pretty bad as we will be editing a system
+configuration file. If you cause some problems, please feel free to ask
+questions about it and I will try my best to help, but I offer no warranty or
+guarantee on this.
+
+With that out of the way, let's get started!
+
+As many things do in Android, this requires root as we will have to remount the
+/system partition.
+
+First things first, crack open your terminal emulator. If you don't have this,
+you can find it on the market, however most roms includes this application by
+default.
+
+Once in terminal emulator, run the following command: 
+
+----
+su
+----
+
+This logs your terminal session in as root(or **S**uper **U**ser so we can
+perform the various operations needed to make the change. Obviously, your
+superuser software will kick in here. Just select Allow.
+
+Now that we are logged in as root, run the following command.
+
+----
+mount -o remount,rw /system
+----
+
+This will remount the /system partition with read/write permissions.  Without
+running this command, we can't save the config file we will be editing in a
+few. The default android has for this on boot is read only permissions, as this
+partition contains some pretty critical stuff (it isn't called system for
+nothing). This is a good security measure to keep programs from changing all
+kinds of stuff on your phone. No worries however, we will only have write
+permissions set up for a few minutes.
+
+Now, open up the build properties file located at /system/build.prop I
+am assuming here that you know how to use VI. If you don't, I am in the
+process of writing up a post on using VI in Android terminal emulator.
+If you know how to use it on a desktop, VI on Android is very similar
+and you should be able to proceed as I detail later how to hit the
+escape key when you don't have one on your phone. 
+
+----
+vi /system/build.prop
+----
+
+Scroll down until you see **ro.sf.lcd_density = 160**. If you change this
+number and reboot your phone, your screen density will change on startup. I
+typically use 120.
+
+Finally, save the file and reboot. For you EVO users who don't have a qwerty
+keyboard with an escape key (who has one of those anyways), press **volume up +
+e**. I believe volume up is the terminal emulator equivalent of ctrl.
+
+Reboot phone for your changes to take effect.
+
+*WARNING (Wik)* : Don't change this value to too small or you won't be able to
+use your phone because everything will be tiny. You have been warned.
+
+*WARNING WARNING (Also Wik)* : When I discovered the build.prop file, I was
+most excited and started poking around. I noticed a lot in there that could
+cause problems for your phone. Be careful when changing the values in this
+file. It can be fun, but you might end up with an unusable phone until you
+reflash it.
