Yes, it's limited to emergency numbers. It depends on your region and probably your carrier which ones specifically. There's no easy way to change it. While it's probably possible to hack that mode, I would advise against it. First because it defeats the purpose of having your phone locked (do you really want someone to steal your phone and call your ...

The purpose of that feature is so that if there is an emergency you can dial an emergency number (911) without having to unlock the phone. Its not so that someone else can use it to call your wife/mother/ICE number. It's not a bad idea since if you were hurt then someone else could inform those people but as I understand its just for emergency numbers ...

If you root the phone, go into Manage Apps and you can disable the dialer, it will remove it from the home page. Contacts can also be disabled. There are also numerous ways to put the phone in Airplane mode so it's persistent after restart.

It is required for phones (at least in Europe and US) to allow emergency calls without requiring the user to unlock the phone or the SIM card. You can always make an emergency call when you're in a cell coverage area and the phone has power. It's a safety feature, which guarantees you can use any phone in an emergency to get assistance, regardless of the ...

The official announcement on the CM forums states: The issue was in the RIL code, which is just typical code and libraries packaged in the ROM (e.g. /system/lib/libril.so, for example). The CM team recommended installing a Samsung ROM noting that any Samsung ROM is fine and any AOSP ROM would have issues. There's no permanent damage since the RIL code was ...

Matthew's comment seems most practical ... But you can try Contact Owner; that displays info for one contact on your lock screen. I use it; it works fine.

On rooted devices, you can disable the following packages to disable all telephony features: Phone Dialer TelephonyProvider Contacts Contacts Storage ContactsProvider Depending on the device manufacturer and OS version, some of these apps might not exist, or be named differently.

tl;dr: I wasn't aware of any such apps and so I've actually written an application that can do this for a university project; the user holds the volume down button for x seconds (default is 3) and a preconfigured emergency message is sent to their chosen contact(s). There are a few problems with getting this functionality however (see below). I haven't made ...

It is now possible to add additional emergency call numbers to your Android phone. The instructions for doing so come from this AndroidCentral forum Go to your contacts Select the "Groups" tab Select "ICE - emergency contacts" Use the icon to the right of "Find contacts" (a silouette with a plus sign) to add an emergency contact. Select an existing ...

Once you hit the gray box & that ICE list pops up, I believe you just have to select a contact from that list in order to assign that person/phone number to the box. Just be careful with assigning contacts to the gray boxes because it can be very easy to pocket dial these people. In case you're interested in removing someone from the gray box, you ...

Not specifically with the volume buttons, but if you are open for alternatives, Tasker might be able to help out. To fire the emergency task, the following triggers might be feasible: Camera button Long-Search button Gesture (The phone has just been waved around in a particular way) Shake (The device is being physically shaken) If the device has no ...

Does it have a removable SIM card? If so, remove the SIM and it won't have any network connectivity except for Wi-Fi. That's what I've done to turn my old iPhones into iPods for my kids.

SecPhome.Apk TelephonyProvider.apk Contacts.apk After freeze them your calling and emergency call will be block down, you can use data connection without any problem from here. If you ...

I added several additional emergency contacts using these instructions. Now 911 is just one of several numbers that can be called from the emergency call screen. I made most of the numbers "dummy" numbers that don't actually connect. While this probably won't prevent all emergency pocket calls, at least 911 shouldn't be a common selection any longer.

Just search for lockscreen in the Google Play Store. There are many lockscreen replacers available. I think Start might be a good one to start with. Make sure to read the instructions on these apps. Some require other apps like GO Locker (requires GO Launcher) to be installed first.

Just a wild guess: Open Contacts app Long-press a contact so that a menu appears Click Edit Click Groups Check ICE - emergency contacts Although I have an S4, I can't try it on my phone due to some security settings.

With Emergency calls you can dial only Emergency numbers like 911 , 112 etc , they differ from country to country. And AFAIK in absence of a network/signal the emergency call is made using the available network of any network provider in region. So the main purpose of "Emergency Call" button is that when in emergency you can dial emergency numbers without ...

This blog has a simple way of initiating a call via the command line. service call phone 2 s16 "+18001231234". Combine that with Vi0's answer, and you could have a script to dial a phone number by pressing the button. I haven't tested this to see if dialing 911 would work, but I don't see why not (unless Android specifically disallows that).

I started implementing my own solution for my device. Here (source) is a program that (started as root) will allow you to start shell scripts using series of button presses. Currently having started this monitor ( andrhard 66 /h/andrhard < /dev/input/event2&) I can easily toggle the flashlight without unlocking the phone (using ...

There are quite many ICE (In Case of Emergency) apps on the market; these apps displays your contact information in your lock screen.
