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?

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?

For the 'what are you using it for, please re-read my OP.
Since southwest has wif on their planes, we should add an "airplane with wifi mode"

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.

I can't say I knew there was a distinction, thanks OP
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'm not a scientist or nothing, but a satellite will probably have to adjust all of 5 inches to search a 600 mile area lol

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
Kind of hard to explain what I want, but when I'm outside using my phone, and then come inside the house I want to keep the wifi on, but turn off the cell antenna to save battery (I find with just wifi on, the battery lasts a long time). I know I can do this by checking airplane mode, but then that turns off wifi, and I have to re-enable wifi, sort of a 3-4 key stroke that I'm wondering if I can do in one?
I've tried power toggles, but couldn't see the option for what I want to do with it.
You could use an app like Tasker, or Automateit (<---has free and paid version). You could have it execute a task when you enable AP mode that turns wifi back on. You can get pretty creative with the tasks as well. I haven't set it back up on my N4, but on my previous phone my need to enable/disable anything was nearly eliminated.
Thanks CMNein, I'll have a look at Tasker.
NFC tags.... I use Samsung Tectiles
You can Program a tag to go into airplane mode and turn wifi on

See if Plane Mode Tweaker works for the Nexus 4. https://play.google.com/store/apps/details?id=com.wordpress.chislonchow.airplanemodetweak
It allows you to configure airplane mode so it won't disable wifi automatically. Also allows you to use bluetooth in airplane mode if it's locked.
I've read that apps to control airplane mode don't work, at least with the stock firmware.

I'm still using an HTC Sensation, but I've got a battery of apps to automate turning airplane mode and wifi on when at home, and back off when away.

Hi there, I have this problem; my AT&T GS4 does not use the deep sleep state. I have made some research, and from what I understood, this problem has to be a result of any program that keeps triggering the phone to get awake.
So, I have the phone unlocked, rooted and ALL the sensors off, expect from gsm signal. With titanium back I have uninstalled the programs that I´ll never gonna use (mostly AT&T bloadware) and frozen the ones that I don’t want to use right know, but maybe by deleting them I would get into a problem (like S-Voice) or just because some day I would like to give them a try. Finally, there are the programs that I would like to keep, but I don’t want to let them make any cpu use while I am not using them. I used an application called Greenyfi, a good example of why this program is the best for the last propose, is the use of programs like google maps, in where I do want to use it, but, just when I open the app. Also, I used the app “Autostarts” to prevent applications to start after some events (like startup, state change, etc..)
With all that been said, I am steel not getting deep sleep, in any situation. I´am not saying that my battery life is bad, I think I can get easily 4-5 screen time use. But, by not getting into deep sleep, the phone is allways using the cpu at 384mhz, so the battery goes down in a range of 1.5 to 2 % per hour (10 hours of no use and 20% less battery).
SO, for you to see the problem better. I did a little experiment. Restart the phone, put it into flight mode and let it “sleep” for the night, the results are attached.
PD: Whatsapp isn’t the problem; I can froze it and still 0% deep sleep.
PD2: Sorry for the language, I forgot to change it.
Get BetterBatteryStats app. It'll tell you what's keeping your phone awake. Look for partial wake locks.

ok, I did it, and BBS says that in partial wakelocks there is no major problem (20seg out of 1 hour the worst app). BUT, in kernel wakelocks, shows that "MSM_HSIC_HOST", is using the exact amount of time since the phone was turned on (1 hour). So, it has to be this. I´ve reading a huge thread of many people having a similar problem (mmsm_hsic_host been the process that wakes the phone most, but not using ALL the time, but considerable time (between 50% to 10). I ‘keep reading until I found a solution.

Bro! I am so trying to get my s4 to not go into deep deep sleep, to be able to have a switch or click here button to be able to toggle that option would be the way for me to continue to use unlimited 4g tether because i was told to use hotspot vpn shield to prevent tim lee mobile from sniffing my data to see if i were tethering ! Although the vpn just told me that the application goes in to deep sleep (aka it turns off!) That's right folks the application turns off without you knowing until it's too late, so let see where to go from here. ??

Yes if you have developer mode to stay awake while plugged in and want to turn the screen off at any point just hit the power button to lock/shutoff the screen.

well the hotspot shield vpn by anchors inc. makes thier app shut down when the phone goes into standby said the tech guy today because it still shut off.
so i suppose i need to prevent standby
ok i got to the bottom of this , hotspot shield vpn by anchors inc.are liars , the tether app auto prevents standby and i also i enabled the developer stay awake optiion. it turns out the application will turn off when no data is being sent for sometime and i have a feeling that it is in their favor for whatever reason otherwise the app would have an option to not shut off
now i was looking into getting termenal_ide to ping google every so often say every 3 or 5 minutes ,
i ran it and it was pinging like a mad man , more then once per second , i though i might get blacklisted for a false ddos
Now I cant be the only want who would want this.
I live in the NYC area and I like to turn on airplane mode when I go into the subway, so I tend to turn it on and off 4 times a day. I also tried to set up a tasker profile to turn on airplane mode at a certain time at night, but because of this confirmation dialog this cant be done. So is there a way to turn off this confirmation.

This would be awesome. I use Airplane mode for a different reason.... areas around me (like a 20min or so drive) have LTE but not *officially* yet so it is a little flaky... and I use Airplane mode to toggle on and off really quick and it switches me to 4G LTE that isn't even officially turned on in the area!
