[Xperia Arc Q&A, Help & Troubleshooting] pvyParts:
Finally got around to checking this for yo guys,

Now it is REALLY easy to figure this out so prepare for a spiel.

if there is an image that you need to figure out. somewhere in an app. this is my process of doing it.

first figure out what part of the app it is in (the Dialer in the main activity)

check for a layout that is named Dialer

/res/layout/dialpad

close enough for me.

look at the xml

do a find fast for background

First hit is

<LinearLayout android:orientation="vertical" android:id="@id/dialpad" android:[COLOR="Red"]background[/COLOR]="@drawable/dial_background" android:layout_width="fill_parent" android:layout_height="@dimen/dialpad_height" android:baselineAligned="false"
xmlns:android="http://schemas.android.com/apk/res/android">

find the drawable

drawable-hdpi/dial_background

check if it is transparent (gimp / firworks / photoshop)

in short your images are

drawable-hdpi/dial_background.png
drawable-mdpi/dial_background.png
drawable-xdpi/dial_background.png
drawable-land-hdpi/dial_background.png
drawable-land-hdpi/dial_background.png
drawable-land-xdpi/dial_background.png

those are the ones you need to change to get rid of the transparent dialer.

follow this process and you will be able to find anything. :) works the same for images text layouts what ever. if you are slack like me use a program like Astrogrep (windows) / Grep (linux) to search the entire folder for short keywords then narrow the search down from there (dial for example here)

this has been a public service announcement by pvyParts :P
