[Q] Motorola Defy: Cell standby drain,airplane mode yes, wifi lan yes, wifi callin no

Have just purchased Motorola Defy.
Have no cellular signal at home. No problem, can run on wifi for internet and also use wifi for calling; Defy feature built in.
Cell standby draining battery excessively, ( 90-100% no signal)= ( 40-50% bat drain). If I use the airplane mode to stop cellular search can use wifi for internet but it disables the wifi calling feature ( known as UMA for blackberries).
Is there an app for the Motorola Defy that will disable cell searching for signal but allow both internet and calling wifi usage??
I am not computer programming savvy at all, you guys are the geniuses.
Love the phone hate this particular cell standby catch 22.
Thanks.

I haven't used this app before but I believe this is what you need, it called "Airplane Mode Wi-Fi Tool"
Here is the description of the app
This tool will help you manage your android phone to connect to Wifi networks (Wireless Internet, or Wi-fi) while on Airplane Mode.
This tool works with any version of Android, including 2.0+, however, it is only necessary if you have a device with Android 1.5-1.6. Android 2.0+ allows Wifi to be toggled while on AP Mode.

Airplane mode by default disables calling in/out, period
Thanks for your reply. I downloaded this app and it does enhance the Airplane mode capabilities but does not resolve the issue of being able to turn off cell standby while still being able to use both wifi internet and wifi calling.
Since I am not on a plane but am, instead, at home I believe what is needed is an app that directly addresses the cell standby searching issue and leaves the wifi settings to behave as intended; enabling the cell phone to fully function via wifi for both internet and calling when there is no cellular signal available, without a ridiculously and unnecessarily huge burden being put on the battery for a completely moot point...
If such an app does not exist then I believe there will be a demand for one and I ,for one, would be happy to donate for such an app.
Again, thank you for your reply.

I just installed the application to see how it works.
When you open the application for the first time there is an instruction how to use the app. Obviously, it was designed to work in real world when one is on airplane. However, if you keep scrolling down the instruction page and read the FAQ section (B) then it tells you how you can configure it to use your wireless settings instead.
I hope that solves your problem.

This is easy: *#*#4636#*#* Go into menu, turn Radio off (toggle ON/OFF in this hidden menu). With radio off both wifi and wifi calling stay active. (USA T-MO)

I was aware of your solution before but I thought that would disable the wireless signal as well otherwise I would have mentioned it. I did a test while my wifi was on and disabled the radio option and the wireless stayed connected.
Thank you for your solution.

Right, but unlike airplane mode it does not shut down wifi calling. BTW, I do not understand the power drain issue. I leave my radio on while working all day, but using wifi with the wifi calling app set to wifi preferred and am seeing no heavy drain. Maybe -- under that same menu -- one should check to see that the "preferred network type is "GSM only." When wifi calling is disabled (even if wifi is active) the phone should default to GSM auto (PRL). I have noticed occasionally it will stay in GSM auto (PRL) with wifi calling on and that might cause a drain, but not sure.

Further to the discussions in this thread I just noticed after restarting my phone (off & on) the Mobile Data feature is enabled again.
There is another menu option called 'disable on boot'. Disabling data on boot did not work once I restarted my phone to test it but the menu showed the feature was still enabled unlike 'Disable Mobile Data'.

This is easy: *#*#4636#*#* Go into menu, turn Radio off (toggle ON/OFF in this hidden
Thank you very much for this info. I was unaware of the hidden menu and this does indeed solve my problem. I will also try the GSM only setting first with radio on to see if that resolves the drainage issue.
I'm completely new to android and this forum and think both are great.
Thanks again.

"GSM only" should be the default when you are running wifi + wifi calling. Set your preferences in the wifi calling app to either wifi preferred or wifi only. Maybe that will stop your phone from searching for cell signals. However, if you kill the radio using the hidden menu it will for sure stop it from searching for a signal. So, if you are still getting drain, it's something else.

Looks like with the new OTA update you can't do this anymore.

[Q] Tasker, wifi calling, gs2, there's no wifi calling app to select

I'm trying to have tasker enable/disable wifi calling when I connect to my home wifi.
I've been following this guide which I'm ok with until we get to the part where it involves the 'wifi calling app'. I used to have a vibrant but now with the gs2 it appears the wifi calling is baked into android itself.
Can anyone point me in the right direction on how to handle this step?

It is not an app, it is a system setting under wireless, so , although not familiar with Tasker, if it does not support system activities, as in selecting system settings, it may not work ......

There is no app for wifi-calling now. They switched to IMS based wifi-calling, and it is integrated into andriod now. 2.3.6 is the version that was released that has wifi-calling built in.
You can see the wifi-calling settings under Settings->Wireless and network. There is a check box to enable / disable it.
I always leave that box checked. So when ever I connect to a wifi network, wifi-calling always gets enabled.
So there should be no need to have a tasker enable/disable it.

Unless you only want to use it on specific networks.

Airplane mode + WiFi calling

Where I live there is -50 bars of cell service, so when WiFi calling drops it starts searching and absolutely murders my battery life. Is there anyway to hack the system to allow WiFi calling while in airplane mode? I've heard certain phones can do it. Are there any devs on here that have the know how? I know we have some very talented people in the community so I'm hopeful. It seems like it should be pretty easy because while on WiFi calling the cell radios get shut off and WiFi works in airplane mode, so?
I'm just not convinced WiFi calling will ever be more reliable and only getting 9-12 hours on a charge really sucks! Anyways, here's to hoping for a fix!

If you go to WiFi Calling Settings -> Conection Preferences -> WiFi Only.
I think that would do the trick.

^ Tried it out of curiosity because it would be useful to me, but that does not work.
I wonder if it would work if you used a program like Tasker to cut only the cell radios without explicitly entering "airplane mode". Although I'm not 100% sure that is possible or if some other work-around is needed.

Maybe there's something that can be added to the csc feature.xml? Not sure what it'd be but theres already these listed:
<CscFeature_Settings_Airplane_Wifi_Dependency>false</CscFeature_Settings_Airplane_Wifi_Dependency>
CscFeature_Web_Bool_StartWIFISettingInAirplaneMode>false</CscFeature_Web_Bool_StartWIFISettingInAirplaneMode>
You could check other devicrs that have wifi calling and see if theirs is listed. This may not even work, but could be worth a look.

Also, there's an app in the store called Bobsled Calling (also a Bobsled Messaging app) listed under T-Mobile top picks. Don't know how good it really is, but I was thinking bout giving it a shot on my old phone that has no cellular service at all.
One of the only ones I've seen where the people you call don't also have to have the app.
Maybe it'll allow you wifi calls under airplane mode?

You can try going to your Phone app and typing in *#*#4636#*#* -> Device information and then hit the 'Turn off radio' button. I used it before when Hurricane Sandy knocked out the cell towers and I was left with just random WiFi hotspots, but this was back on ICS. Though I don't see why it shouldn't work with JB.
If the code doesn't work, go to the Play Store and download an app called 'Phone info' (Author: [email protected]). The app should take you to the Testing menu.

Instead of constantly typing all those numbers (*#*#4636#*#*), download the app, Phone Info in the Play Store and there you go....

That app doesn't work because when WiFi calling is working the radio is idle. Service menu is a no go.
Sorry I didn't post it as a Q but I didn't have a clear question. I wanted to discuss the topic. I thought about yet where to post it before I did, thanks.

WiFi calling with Cellular Radio turned off
I am trying to accomplish the same thing but was approaching it from a different angle. The service menu idea doesn't work.
We are both trying to accomplish the same thing. Use WiFi calling while having the Cellular radio turned off. Airplane mode turns off all radios and you can re-enable the WiFi radio. However the Galaxy S III will not allow a call to be made while the phone is in airplane mode. This is a low level system issue and not related to the dialer (I tired three different dialers).
Does any body know of a way to do this??? PLEASE??? I'm leaving for Brazil in 4 days for a month and I would like to be able to do this in Brazil.
This is a copy from another posting:

According to Samsung & T-Mobile the only official way to turn of the cellular radio is to enable Airplane mode.
Here is the procedure that I tried:
Enable Airplane Mode
Turn on WiFi
Connect to a functioning WiFi hotspot
Enable WiFi Calling
Wait for the WiFi Calling Icon to appear in the status bar
Make a WiFi call
At this point the dialer sits at the dialing screen for more than 10 minutes (I bailed at 10 minutes). As soon as I abort the dialing attempt a dialog box pops up saying you cannot make a call while in Airplane mode.
Is there any way to completely disable the cellular radio without putting the phone in Airplane Mode?
Is there an app that will do this?
Is there a hidden that will do this?
Please don't use bandwidth by asking why I want to do this or suggesting that I use Skype or some other app. My goal is to be able to make and receive VOIP calls while the cellular radio is completely disabled.
Thank you for your help...

I think maybe the phone HAS to ping a cell tower in order to make WiFi calling work. For your purposes just set the WiFi calling connection preference to WiFi only.

I have zero reception at my house and wifi calling works.
Setting it to "WIFI only" doesn't allow it to work the way that's wanted - it just tells the phone to only make calls over WIFI - but that doesn't open up the ability to do so when the radios are off. From what is described I agree that this sounds like a conflict with the low-level integration.

Did anyone try that Bobsled app I mentioned earlier?
It claims that I could put it on a tablet or my old phone that has no sim/data, and it would work.
If it were to work is that something that could get you by for a while? I understand not wanting to go 3rd party, but it could be the only option for now. It is a tmobile app btw.

I meant for the guy going abroad. Although he needs to also make sure data roaming is off, I think.
Doc I did look but my problem is I want to use my tmo number. I have a house phone but it's really frustrating to tell people they have to try me at two different numbers. And not being able to text.

There's also a Bobsled messaging app. Pretty sure its the same deal and works via wifi.
Also, I could've sworn it said that you have the option of using your current cell number. Maybe I'm mixed up on it...
Anyway, its just a suggestion for looking at. I have no idea how good it really is... just don't have many other ideas for you guys at this point.
I wonder if there could be a build.prop value that would disable cellular only. Or set its scan frequency like you can do for wifi.

I have done some more research.
I was able to turn off just my cellular radio by using the phone info application to enter the service menu (Phone Info App->Device Information, scroll down and select Turn off radio).
With the cellular radio turned off I tried to enable Wifi Calling (Settings->More Settings->W-Fi Calling).
The phone says "enabling", turns on the cellular radio (without any messaging saying that it is doing this) and then says "Ready for Calls".
I also tried enabling WiFi Calling first and then turning off the cellular radio (using the method outlined above). But the cellular radio would not turn off as long as WiFi calling is enabled.
I don't know if this is a bug or a "feature" but for WiFi Calling to work on the T-Mobile SGH-T999 (4.0.4 Firmware) the cellular radio must be enabled. Though I'm sure T-Mobile has a reason for this the logic of it escapes me. WiFi calling should not need the cellular radio for any reason. I use Skype all the time and it doesn't need cellular service to operate on WiFi.
If anybody out there knows how I can make and receive phone calls using my regular cell phone number exclusively via WiFi (with the cellular radio disabled) please let me know. Many thanks to the person who figures this out

As long as you are connected to Wi-Fi, with Wi-Fi calling activated (blue icon showing), it should automatically disable the cellular radio. If you are connected to Wi-Fi, but no blue Wi-Fi calling icon, then it will turn on cell radio and start searching for towers.

Duh.. the reason to use it in airplane mode for me is that WiFi calling disconnects every few minutes and when the cell radio is searching since I have 0 coverage it absolutely kills my battery.

Sorry but you're not making any sense. You're complaining about your phone's search for cell towers killing your battery because your Wi-Fi calling keeps disconnecting? Let's say you find a way to disable your cell connection. Your Wi-Fi calling still keeps disconnecting and you still can't receive or place calls. What's the point? Longer lasting "iPod"? Maybe start looking for a way to fix your Wi-Fi calling problem would be a better solution, ie. Flashing a different ROM until you find something more stable. Duh!

These are the following options available (all of these options have the cellular radio enabled and working at all times):
1. Make calls using the cellular network only - WiFi Calling disabled.
2. Wi-Fi Preferred - Make calls using WiFi Calling if a valid WiFi network is available and connected. Cellular network calls are made when a WiFi network is not available.
2. WiFi Only - Makes only WiFi calls. Cellular calls are not made when a WiFi network is not available. Note: This does NOT disable the cellular radio.
3. Cellular Preferred - Makes cellular network calls are made if a cellular network is available. WiFi calls are made if a cellular network is not available and a WiFi network is available and connected.
When enabling WiFi Calling the cellular radio is briefly disabled and then re-enabled..

I've tried multiple ROMs and multiple routers so.....
My only "solution" would be to not use my phone at all at home and just turn it off. I'd rather have a longer lasting iPod than a paperweight.

Toggle network mode to 2G when connected to wifi

I'm looking for a automated way to change "network mode" to GSM when connected to wifi. My issue is at work I don't very good LTE/3G service, but great 2G reception for phone calls/SMS and since I'm on my work wi-fi I don't care about having LTE data. I looked briefly into tasker, but looks to be a bit of a challenge due to the pop up when changing back and forth.

Llama is the app you need. Like tasker but way easier set up
You can trigger your event by GPS location or by wifi network.
Set it up so when you connect to a WiFi network it disables your data connection. When you disconnect your Wi-Fi network it turns on your data connection.
Works great and it's free

Automate WiFi Calling On/Off

Thanks for reading.
I am looking for a way to automate turning WiFi calling on/off. I have attempted to do this with Tasker but with no luck. I have read several threads but they seem to be referencing an older WiFi calling solution that was an app.
I am using the T-Mobile Samsung S4 w/ 4.3 and the WiFi calling settings are under Settings->My Device (Tab)->Call->Wi-Fi Calling. this phone is not rooted (corporate policy) so there I cannot use D-pad instructions to select the option.
Any thoughts?

I just took a look at the code, I think you are out of luck without root my friend. :/

I was under the assumption that it was automatic.
With Wi-Fi calling on and you're out of Wi-Fi range cellular network take over. There's a few options under Wi-Fi calling setting as to which you prefer first, Wi-Fi or cellular signal

Your assumption is correct, however if you set it to Cellular preferred and you get a call with only 10% cell signal it will come across the voice channel, and in my case most likely drop. This is when I am at the office. Conversely when I am at home my wireless coverage is spotty and I wouldn't want to use WiFi calling. So my ultimate goal is to use Tasker to turn on WiFi calling when I am at the office and turn is off when I leave. I hope this clarifies what I am trying to accomplish.
