Second: Editing the String of your Setting apk

Difficulty: ★★☆☆☆

1. First open a file manager and after that go Settings where it is decompiled
2. Here look for res/xml/settings_headers.xml and open in your text editor
3. Simply find the header which you want to edit. And in this we will change “Developer settings” Noobs keep out. Also we need to change the string referenced in this code:

<header android:icon="@drawable/ic_settings_development" android:id="@id/development_settings" android:title="@string/development_settings_title" android:fragment="com.android.settings.DevelopmentSettings" />

Now we need to change the android:title reference, so open your Strings.xml, for your language (if it’s not in there, open the default one)
You can find the string (use Ctrl+F) which we found previously, so that we can search for “development_settings_title”

<string name="development_settings_title">Developer options</string>

After that change the bit between the > and the < to what you want:

<string name="development_settings_title">Noobs keep out</string>

<header android:icon="@drawable/ic_settings_development"  android:id="@id/development_settings"  android:title="@string/development_settings_title"  android:fragment="com.android.settings.DevelopmentSettings" />

5. After that simply edit the android:icon location to the icon according to your wish. You will find icons in res/drawable-hdpi, mdpi, ldpi and xhdpi (depending on ROM)

We need to change it to ic_settings_advanced, so it like:

<header android:icon="@drawable/ic_settings_advanced" android:id="@id/development_settings" android:title="@string/development_settings_title" android:fragment="com.android.settings.DevelopmentSettings" />
