[Verizon Samsung Galaxy S III] Didact74:
This MOD/GUIDE will add a working brightness slider bar and Wifi quick button to your drop down status bar.

I know there are some other mods out there that do this by adding lidroid-res and a quick panel APK but this will do it with just some smali edits so no new APKs to install. This is just the brightness slider and WiFi quick button, not the 15 quickbutton mod

This has been tested on a STOCK DEODEXed LG7 ROM. If you want to add this to a custom ROM you will likely lose some other MODs/Themes.

Always Nandroid First!

Dev's, if you want to use this in your ROMs feel free but please throw me a thanks and some credit.

Here is the guide.....

We will be de/recompiling SystemUI.apk.

Navigate to res/values/arrays

find the following code

<item>Bluetooth</item>
<item>Location</item>
<item>SilentMode</item>
<item>MobileData</item>
<item>AutoRotate</item>
<item>PowerSaving</item>
<item>AirplaneMode</item>
<item>DrivingMode</item>
<item>Sync</item>

Change it to the following:

<item>Wifi</item>
<item>Location</item>
<item>Bluetooth</item>
<item>SilentMode</item>
<item>MobileData</item>
<item>AutoRotate</item>
<item>PowerSaving</item>
<item>AirplaneMode</item>
<item>DrivingMode</item>

Feel free to change the order of the code above to suit your needs. They will layout in your quickpanel in the same order you put them in above.

Navigate to res/layout/tw_status_bar_expanded.xml

Find the following code and delete the part in RED only:

<LinearLayout android:orientation="horizontal" android:focusable="true" [COLOR="Red"]android:visibility="gone"[/COLOR] android:clickable="true" android:layout_width="fill_parent" android:layout_height="56.0dip">

That will make the brightness slider visible but not yet functional.

Navigate to smali/com/android/systemui/statusbar/phone/PhoneStatusBar.smali

Add the following lines below in GREEN

.field private mBatteryTextObserver:Lcom/android/systemui/statusbar/phone/PhoneStatusBar$BatteryTextObserver;

[B][COLOR="SeaGreen"].field mBrightness:Lcom/android/systemui/statusbar/policy/BrightnessController;
[/COLOR][/B]
.field private mBroadcastReceiver:Landroid/content/BroadcastReceiver;

For the next step there are a lot of changes that need to be made in the Method. For the sake of time and this guide, we will simply C&P the entire method with the revised one. If you are anal like me and would like to see exactly what is being changed, simly use your editor compare tool to see the differences.

Find the following line:

.method interceptTouchEvent(Landroid/view/MotionEvent;)Z

Starting at (and including) the very next line delete all code all the way up to (and including) the first "end Method" you come to and paste in the following in its place. You may want to copy half the code and paste and copy the other half and paste. One C&P may not capture all the code at one time.
