Moments ago in this thread, TheRealBev discussed "Roaming" settings.
I just made a one-tap shortcut to the Galaxy setting for Roaming=on/off.
Note that this activity is NOT found in the Android settings package! (So you need to know more about the name in order to make a shortcut).
Keeping in mind there are many ways to create a 1-tap shortcut. Each one-tap shortcut may have slightly different circumstances.
Which means you need to be intelligent about creating that shortcut. Here is what I just did to create that one-tap shortcut to roaming.
- Use Shortcut Widgets (+ Inspector) by Hamed Nikbakht to find a. unique package name = com.samsung.android.app.telephonyui b. unique activity name = .netsettings.ui.NetSettingsActivity
Note this is a different package than the typical Android settings.
- Start App Manager by Muntashir Akon & search for what you found Search for "com.samsung.android.app.telephonyui" & tap the result which brings up the "Call Settings" app to the "App Info" tab.
Tap on the "Activities" tab and scroll down to where you see "Mobile networks" for "com.samsung.android.app.telephonyui".
Then tap on the blue "Create Shortcut" button. Optionally edit the icon image and name as desired. Place onto your homescreen as desired.
Note that the package is colloquially called "Call Settings" (and note that this package may be unique to Samsung devices).
- To test, tap on that newly created homescreen shortcut. Voila! This will bring you directly to the roaming on/off activity! com.samsung.android.app.telephonyui.netsettings.ui.NetSettingsActivity formatting link
