<SwitchPreference android:title="Internet" android:key="tweaks_speed_view" android:summaryOn="Show" android:summaryOff="Hide" />
</PreferenceCategory>
<PreferenceCategory android:title="Networkspeed">
<com.wubydax.romcontrol.prefs.ColorPickerPreference android:title="Download speed color" android:key="tweaks_speed_color_download" android:summary="Choose download speed color" android:defaultValue="\#ffffffff" alphaSlider="true" hexValue="true" />
