Turn off just the cell radio? - Epic 4G General

Can this be done? I tried switching on airplane mode, and then enabling Wifi/BT individually -- won't let me.
So, how do I turn off the cell radio, but turn on Wifi to take advantage in-flight wifi?
Also, when using local media, I'd like to sometimes turn off the cell radio to save power but listen with my BT headset.
I'm probably a total dufus and this is obvious, but I can't find it. This was easy to control on my WM Omnia II. I still like my Epic a bajillion times better, but this is a bit annoying.

Airplane mode cuts off all communications. Hence, "airplane mode"

There's some apps that'll let you do that, as well as Froyo when we get it officially, or if you want to run a leaked version.

Tasker will allow you to switch off the radio only. You would have to just set up a widget for that particular task.

In the leaked froyo, I had airplane mode on to test it and I put the wifi on byaccident and it was working with no cell signal, but I figured it was just a bug with it considering its beta and when ever I did tht before, airplane mode will cut off. I'm glad to know its a part of froyo now...that's going to come in handy

I'm running Android 2.2 and it isn't working for me -- once airplane mode is enabled, Wifi and BT will not turn on.
I would hope that in a future version of Android they will simply add the cell radio to the icons so it can be turned off like the others.

Can't you go to your settings, under wireless and networks, and disable 3g data?

You can however it will still be looking for a cell signal to use for voice.

Exactly. I don't get reception in the building I work in, so I don't want it to drain the battery trying to find signal.

I'm running stock EC05 and I can turn wifi on in airplane mode (I can't speak for bluetooth though). GPS, however, does not work once you turn airplane mode on.

That's odd. I am running SFR 1.1.1 and if I turn on airplane mode and then push the Wifi icon, the text changes to "on" but the blue light never turns on -- it's as if it's trying to turn on but can't.
GPS works just fine -- it never switches off in the first place when I turn on airplane mode.

That's because GPS is rx only. It doesn't need to tx to acquire a GPS lock.

I've been trying to figure this out as well as I'm going out of the country and will be carrying my phone.
Only way I found to do it is:
1. In the dialer press###
2. Click view, and write down your MSID# and msn#, than go into edit
3. You will see your phone number and a box on the bottom that says touch here. Touch there.
4. Keypad should appear. Just press enter.
5. Another screen showing your MSID number should come up almost instantly. Press enter again.
6. Back out of this menu and your radio will be off (may turn off sooner, once it's off it's off)
Done
*MUST USE AREA CODE WHEN INPUTTING PHONE NUMBER*
now for the important part.
Turn your radio back on.
1.same as previous steps except instead of just pressing enter when the key pad comes up, input your phone number than press enter.
2. Input your msid number on the second screen and press enter
3. Click done on the main menu. Phone will reset.
Process honestly takes 30 second once you have your msl.
Edit: only issue I have is after the reboot when u turn your radio back on, the phone asks for your gmail password again.

N1 data connection issue... please help!

Hi everyone, I had a quick question I needed your assistance on.
Sometime I put my N1 into Airplane mode to save battery and when I finally turn airplane mode off I can never seem to get a data connection unless I totally shut off the phone and turn it back on again. Coming out of Airplane mode there will be a 3g signal on the status bar but only the up arrow will light up and anything needing data (browser, market, etc) wont work unless I totally shut off the phone and turn it back on again. Is this happening to you too?
The same thing happens if I open up the Quick Settings app and turn off mobile data (to save battery) and when I turn mobile data back on I have to restart the phone entirely for it to work properly.
It seems like my phone might be having an issue with data connection so I might have to call up HTC about it but I wanted to find out from the other members on the forum if this was happening to them too.
Thank you for your help
It's happened to me before using APNdroid.
Apparently you can fix it by turning the radio on and off in the testing menu (*#*#4636#*#), never tried it though.

You don't need the 4g toggle widget on. Even if it is off it will auto turn back on after a reboot.

See first post.
Use the Wireless settings menu to enable and disable 4G. That will keep it from restarting after reboots.
How often do you reboot anyway? I'd certainly like to see a fix, but I don't have any problem just remembering to turn it off after a reboot if I don't want it on. It's a small price to pay to have more convenient access to 4G toggling (right in the notification screen, as well as in Quick Settings).

The issue isn't just remembering to turn it off, there's another issue here. The evo doesn't turn off 4g correctly. Test it yourself. Turn off 4g, then wait a while, and check an alogcat log. You'll see that it still tries to connect and scan for 4g every few minutes, only to end up erroring out (because 4g was turned "off"). This is a potential battery drainer also.

GPS in airplane mode

Last time I flew, I tried to get a GPS lock while cruising (in airplane mode obviously), but was unable to get a lock. I assumed it was some kind of bug with EB13, since there where so many complaints of GPS issues with EB13, even though I've never had any issues. I have gotten good gps locks before with an old garmin I flew with long ago.
This morning, before taking off, I tried an experiment: get lock while not in airplane mode, then see if I could get lock in airplane mode. What I found was GPS would continue to function after turning airplane mode on until the phone goes to sleep. After it goes to sleep, or if you turn it on after entring airplane mode, gps does not work.
Is there any way to keep gps functional while the phone is in airplane mode? Maybe I'm weird, but I sometimes like to be able to see where we are when I'm flying. Only 'gotcha' is google maps needs data to function.... are there any map programs for android phones that can store maps on the sd card?
Sent from my SPH-D700 using Tapatalk
Airplane mode by it's nature means any and all radios are turned off, 3g, 4g, wifi, gps, everything. It'd kind of take away the point if you kept gps on
Not exactly. GPS is a passive radio, meaning it can receive, but not transmit. Airplane mode is meant to turn off the active radios (radios that receive and transmit) so as to not 'interfere with aircraft instrumentation' (which is a load of bull sugar, but that's not the point of the thread). In fact, I'm pretty sure, from long ago, that "GPS devices that do not transmit" where in the approved devices list.

Gps is one thing that is strictly prohibited for use on a commercial airline. Airplanemode is supposed to disable all transmit and receive function on your phone. Also the only good it would be is if you have maps stored in your phone because you won't have data either. What are you using it for?

Sent from my SPH-D700 using Tapatalk
The GPS wants to find some sort of cellular signal to it can estimate its location before giving you an exact satellite location. This is the same for any phone. GPS will detect satellites but will not lock if airplane mode is on. I've tried this on an LG Ally, HTC Droid Eris, and even the Samsung Epic.

There's a navigation app called CoPilot that stores on SD. I don't know if it'd give you views of the ocean though. It might be land only.

Pretty sure that the 4th one over in the top line of "Permitted Above 10,000 feet" says "GPS recievers"
When you get done wiping that egg off your face......
As for an Airplane with WiFi mode, I found that's not needed. Turns out while in airplane mode, WiFi will turn on and work.
So how about it? Think there's a way to modify airplane mode so it'll leave GPS on? If I had half a clue about programming and such, I'd try, but that kind of work is way over my head.
Does any GPS work when encased in an aluminum can....I mean airplane? i wonder if your original lock was from AGPS (tower assisted), once you lost tower data and the phone was in the can....er plane, it couldn't receive satellite data.
Yes, it does if youre by the window. I got a lock with my epic sitting at the gate, and a while back I got a lock with a garmin streetpilot iii.

Maybe I'm over simplifying this...but I just turned on airplane mode, then enabled gps & wifi from the pull down.
Opened maps, got a lock, working as usual.
Airplane mode afaik just keeps all cell signal off.

....as one earlier post alluded to, needing airplane mode on in an airplane is a load of bull-hockey (bull sugar,lol)...the real reason they ask this is so that you're not distracted should something go wrong, like a wing being on fire, and you can then alert some one in charge. Straight from the flight attendants manual.
So long story short, there's your solution OP. Just leave the radios on, and keep it on silent so no one hassles you.

Not sure what the deal is, but I'm pretty sure airplane mode affects GPS in some fashon. Sitting in the airport this am, when in normal mode, it would get a lock, and when I turned on airplane mode, it would work until it went to sleep or I locked it. Then when it woke up, it wouldn't pick up a single satelite, weather I had GPS on when I put it into airplane mode or if I turned it on after the fact.
Sitting in my mother's living room, it worked either way, then my phone got stupid, requiring me to pull the battery to get it to respond, then it started acting like it did this am. Wierd.
Perhaps getting a lock at the gate is a lot easier for the phone than getting a lock at 600MPH?

I've tried GPS on an aircraft several times and could never get it to work. This is in full mode w/ airplane mode left off.
Celluars DO NOT interfere with aircraft, at all, and its a dumb ass law, supported by those who are more concerned with ripping you off by overpriced services. Civil GPS mode does however have a speed limitation which is what may be happening....not sure what aircraft you tried it in, or what speed.
I have had it work correctly in a cessna before though.

Sigh......
The satellite doesn't care what you do or where you are, it is totally unaware of your GPS device. However, high speeds can make receiving any HF digital transmissions more difficult due to the rapidly varying multipath and phase errors. If the receiver in your GPS device isn't designed for use at high speeds you may not be able to get a lock. lol

Thanks for the love (these are my issues), but it's too little too late. Android has written us off and closed the issue again.
I'm giving up on this one and won't be opening a replacement issue. Clearly the Android team has some hidden agenda (my guess would be a carrier wants to stop users from doing this) and is acting shady about it.

That's funny, last time I flew American, I had my phone in airplane mode, but was still able to connect to wifi. As a matter of fact, I'm sitting in my house with airplane mode on and connected to my wifi network as I'm typing.
I understand that the option is to keep data off and voice on, but don't be such a jerk about something.
Wifi mode gets turned off, but can easily be turned back on even while airplane mode is on.
This topic has nothing to do about wifi! No one cares what you can and can't do... it's about turning off the 3g radio for better battery life and leaving voice on still.

Trouble with Juice Defender and Cyanogenmod

Ever since I got Cyanogenmod 7 working on my phone, I've had a lot of trouble getting my 3g to toggle back on after turning my screen on. I'm using JD for the toggle so is it a Juice Defender problem or a modem problem?
Sent from my SCH-I500 using XDA App
I have the same problem, I just switch to airplane mode and back and it fixes it. It only happens periodically, it works as it should more often then not. I attribute it to CM7 awesomeness. At least JD works, Green Power won't even try to manage the data connection.
Ah I wouldn't have thought to try that. Yeah I love this rom compared to stock so I'm more than willing to put up with a few gripes.

I have this same problem and run JD but it's not a JD problem. I would say it happens to me once or twice a day(usually when the phone is powered on for more than 6 hours without a reboot). A lot of people have this and toggling back and forth between airplane mode fixed the problem pretty damn easily.
If you want a quick way to do this go to
settings
cyanogenmod settings
interface
notification power widget
widget buttons
select airplane mode
Now you have airplane mode in your pull down bar and you can quickly enable it and disable it when this happens.
I have two problems relating to this. My 3g wont turn on automatically when someone sends me an MMS. Usually my stock ROM would turn the 3g on and download the MMS, but now I just receive a text message from a number rather than the name of the contact, and I need to press a Download button to download the picture/MMS. Then I have to turn on my 3G manually, then I have to press the Download button, and only then do I receive the picture/MMS.
Also, It has been happening quite often now. My 3G does not turn on, even when I turn it on manually so I have to reboot my phone an only then will it turn on.
Im using CM7 nightly, latest one up to date on HTC Desire HD.
Hope someone fixes this!
