In the past, when I have had devices with GPS when I start up the app that uses it, GPS starts automaticaly and stops when you close the app.
now whenever I use Google maps or such I always forget to star GPS first is there a setting?.
I just leave the GPS on all the time. My observation is that it doesn't do anything unless an app uses it. My settings are:
Use wireless networks - not checked
Use GPS satellites - checked
Use assisted GPS - unchecked
I have all three options checked for quicker gps locks...
I never have GPS enabled unless I need it. I have the toggle on the home screen in my power control Widgets config.
I am wondering though, why would you have location by wireless networks not enabled?

I don't use location by wireless networks because I will not agree to Google's terms of service to do so. By agreeing you allow Google to collect location info from your phone even when there are no apps using any location services. I honestly think that this is why some people have battery issues when they leave GPS on. I do not see any way to opt out of this collection of information even if you turn use wireless networks off.
I don't use the assisted GPS because it states on the settings page that the GPS is more accurate without it.
I see the same battery life with GPS on or off.
The whole point is battery life, I dont use the gps all the time and I have a mugen 1800 battery but that still need charging after about 6 hours even with gps off.
But to go back to my original question is there a setting or app to allow the turning on of gps when its needed
Settings/Location and security. Maybe search the market for a widget

You can use tasker to automate turning on the GPS when you run specific apps.
As I wrote before I leave GPS on all the time with no adverse effect on battery life. I honestly believe that you only have issues with the GPS and battery life (when not using nav) if you accept the Google terms of service for location by wireless networks. Even if you then turn off that settings there is no way to revoke the permissions you give Google so they can use your GPS in the background for their data collection.
Interesting mine says uncheck to reduce network usage. What froyo are you running? But network usage is the main battery life consumer on my phone, I may go a couple days with that unchecked to see what the effects are even though I have no problems with my battery life.
Here's my phone info:
Hi,
I just bought a Sony Tablet S, amazing device. The only problem I'm having is that when the tablet is idle, or the screen shuts down, the WiFi gets disconnected and it doesn't reconnect untill I open the WiFi panel in the settings app.
Now before you guys jump to conclusions, yes, I changed the WiFi disconnect policy to "Never (uses more battery power)". That hasn't helped at all.
Any ideas? Is this just with Sony S or a generic Honeycomb thing? Tablet hasn't been rooted as yet.
Try Advanced Wifi Lock Free. It works well with my tablet.
This issue seems to be a bug in Tablet S. I hope they'll fix it in the ICS release
Yes, already discuss here...
You need to install a must have application...
Advanced Wifi Lock
https://market.android.com/details?...DEsIm9wb3RlY2guYWR2YW5jZWR3aWZpbG9ja2ZyZWUiXQ..
Worked
Thanks for the app recommendation. It's working...so far .
I bought my Tablet S 2 days ago.
Though I have heard of this issue before, my new tablet does not have this problem, maybe Sony has fixed the bug.
p.s. I changed the wifi disconnect setting to Never.
I started using wifi advanced lock a couple weeks ago and it works great! Much better than making sure the screen stays on during all your downloading
...Although I've noticed a massive change in battery life. Typically I was always getting 7-8 hours of screen on (gaming) time out of it, with up to an additional 24 hours of time with it on standby.
Now I got about 13 hours standby and 4.5 hours screen on time with wifi constantly on.
All I'm saying is to have a widget for turning on/off wifi quickly, and leave it off when it's not in use. I didn't think that wifi made THAT much of a difference..but apparently it does lol (and that was still without autosync on either)
I uninstalled that and use spare parts instead. Advanced wifi lock was horrid with my battery grrr
I think is normal, because if you put your tablet in standby is because you're not using them so why you need wifi on?
When you turn on again the wifi will reconnect auto again
WPS Wifi Lock
I had the same issue when connecting at my house, If you have a WPS enabled routter, connect to you access point using WPS. At keeps the signal locked.
Hey guys, first off, I have searched for no less than 2 hours for an answer to this question, and while there are lots of discussions, none of them seem to replicate what I am seeing.
Can anyone confirm this, and does anyone have a fix?
GPS will not lock a single satelite in Airplane Mode. I'm in American Samoa without cell coverage, and using the GPS Status app to test. Here's my findings:
First, I turn off Airplane mode, turn on WiFi (connected), turn on GPS. I do not get a cell signal. I open GPS Status, GPS locks onto the first satelite within a minute, and locks position in 10 seconds after that. I turn Airplane mode on which turns WiFi off. Interestingly enough, GPS is not turned off. I turn GP Soff, and then turn it back on (have read suggestions to do so, and have also tried not switching it at all). I then turn Wifi on and verify connection. I open GPS Status, and let it sit for up to an hour outdoors, not a single satelite ever appears. I turn Airplane mode off, and within a minute I have a locked location.
So, two questions, is it possible to get GPS to work when in Airplane mode, or is it possible to disable the cell radio some other way (possibly keeping GPS enabled)?
Here's my stats:
Phone: Moto Razr Maxx
Rooted: Yup
Carrier: Verizon
Sys Version: 6.12.181.XT912.Verizon.en.US
Android Version: 2.3.6
Baseband: CMDA_N_04.07.01R LTEDC_U_07.1F.00
Purchased about a month ago
Playing around a bit more, I noticed that when I have airplane mode off, and GPS on, and GPS Status open, if I quickly hit the home button, turn Airplane mode on, and go back into GPS Status, a lock remains for about 3-5 seconds, and then satelites slowly start disappearing until there's none left. Airplane mode is definitely disabling GPS on my phone.
Anyone? Bueller.... Bueller... Bueller...
I can post video if you don't believe me...
I have read that the GPS needs a data connection to make a lock. I don't remember where I read that, but I had the same problem when I was in Europe trying to use my phone primarily as a GPS device with cached maps. There was maybe once or twice that it actually locked, out of many many many many attempts.
I have airplane mode on, wifi and blutooth off, then turn on gps, I get gps lock on my Droid Razr with stock gingerbread for a short period then lose all satellites. It appears that you can't use gps with airplane mode on.
bump i have been wondering about this also. airlines often expressly allow gps. after all, gps RECEIVES, it doesn't transmit.

Actually GPS doesn't need data connection to make a lock. But with data connection it helps make lock much faster.. that's the features called A-GPS (Assisted-GPS), google around about A-GPS for more detailed info how it works.
I always turn off my data connection every time i use my razr for navigation. I only turn data connection sometimes to make the GPS locked and after i got a lock i always turn off the data connection (I'm not on data plan) and even i didn't turn on my data connection I still can get a lock as long as i am outdoor. So far i never had razr GPS lock problems. This phone's GPS never disappoint me.
My guess is maybe it's some kinda bug on the airplane mode or maybe that's intentionally for some safety reasons.
Same here. I did:
- open maps, locate my position. ok.
- turn off wifi and data
- go back to maps, position ok.
- longpress power, turrn on airplane
- gps starts blinking, position lost
- turn off airplane, but data remains off
- gps position found in 2 seconds
(also tried with "GPS Test" app - same result)
I have MAXX AsiaRetail stock 2.3.6
Sent from my XT910 using XDA
Thanks guys, nice to know it's not just me! Just to clarify some other posts, GPS works with or without a data connection as long as airplane mode is off.
So, seeing as though airplane mode kills GPS, does anyone know of a way to disable the cell radio (to save battery life) without turning on airplane mode?
And just to comfort those who worry about flying, I'm just using the phone for directions and what not (American Samoa doesn't have street addresses believe it or not, and 2 houses past the third palm tree doesn't cut it ). I download the directions while at the hotel on wifi, then go about my way, but if I can't use GPS in airplane mode, it kills the battery searching for a cell tower.

Couldn't agree more, while in the states with cell reception, this phone's GPS is fantastic! Unfortunately, if you have to keep airplane mode off to have it work, it's useless in the back country, or 3rd world countries. Maybe today's ICS release will fix the bug!
I don't think it's a bug. My droid X did the same thing.

Moved To Q&A
Please Post questions in the Q&A section
On my Razr Maxx I also have no gps in airplane mode. I'm running the official 4.04.
I'm going to guess this is because the droid radio chip has gps integrated along with the cellular radios. Here's my evidence:
Turning off the radio with the LTE OnOff app (it just opens the radio service menu, same as dialing the service number), and pressing "Turn radio off": Gps Test would never see any satellites and would never get a gps lock.
Setting the "preferred network type" to "GSM only" (this has no service in Seattle with Verizon): Gps Test immediately sees satellites and I get a gps lock.
I wish there was an option to turn off all the cellular radios but to leave the gps radio on. I use my razr maxx hiking with offline topo maps and OruxMaps, and it lasts about 8 hours recording tracks every 1 minute.
Possible solution?
My findings are that when using my Razr Maxx still on 2.3.6 stock settings, If I run the GPS Test application with GPS, 3G data and cellular on (airplane mode off) it acquires my location accurate of 10 feet, using 8-12 satellites in approximately 10 or so seconds. If I exit, toggle Airplane mode on, relaunch GPS Test, it will acquire my location in the same time, accuracy and with again 8-12 satellites. But If I exit, toggle GPS off and then Airplane mode on, Toggle GPS on, relaunch GPS Test, it will not be able to locate any satellites.
Now, with that said, if I go into my data/data/com.android.providers.settings/databases/ directory and open the settings.db file, in the "system" entry, I do not have gps listed in either the "airplane_mode_radios" or the "airplane_mode_toggleable_radios" values. I do have "cell,bluetooth,wifi" under the airplane_mode_radios value, and "bluetooth,wifi" under the airplane_mode_toggleable_radios value.
I do not know how this looks in ICS for the Razr (4.0.4). I also do not know if gps is even able to be included here. Just a theory.
I might be on to something that may work and you will need to be rooted.
I warn you, that I have not tried modifying this myself, so I cannot verify it will work. Do not try this if you aren't comfortable with attempting it without it being verified to work first.
What I'm thinking is to use an app like Root Explorer and navigate into the data/data/com.android.providers.settings/databases/ directory. Open and edit the settings.db file with an app like SQLite editor. Then open the "system" database entry. Check to see if on around lines 21 and 22 there are entries named "airplane_mode_radios" and "airplane_mode_toggleable_radios". Once located, check to see if their values include gps among the other available radios. If the airplane_mode_radios value includes gps, then long press, tap edit field, remove it and save. If gps is not listed under the airplane_mode_toggleable_radios then long press, edit field, add gps and save. Exit and reboot.
I think with doing this, it should not turn GPS off when airplane mode is toggled on and it should allow you to toggle GPS on and off while airplane mode is on.
If anyone else knows of an easier or proven way to do this then let us know.
If you know this will not work, correct me and let me know.

I'd like to confirm that I'm having the same issue of having no GPS connectivity when in airplane mode even though the GPS has been toggled on. Numerous other forums have stated that this is a hardware issue with Motorola phones. I'm curious if the above quoted solution has worked for anybody.
Thank you!
This is the response that I got from Motorola after asking the general question about having GPS turned on when airplane mode is on:
"When airplane mode is enabled, this will automatically disable all wireless and radio communication on the device including the GPS receiver. Because the phone, in order to determine location, takes readings from both GPS satellites and nearby cellular base stations (towers), with the help of a location server on the network. In other words, the phone relies on the network for help in determining location. Although the phone does receive GPS signals directly from the satellites, it can't determine actual location without help from the cell network."
Therefore, you can't use the GPS radio by itself.

But the GPS still works fine when I am far away from any cell towers of any kind...
I think whoever responded to you was trying to justify airplane mode turning off GPS. There must be a way to force it to stay on.
It has certainly frustrated me that I can't use airplane mode to save battery while using GPS.
I'm by no means an expert on this issue but I think the GPS and cellular radios are physically connected (on the same chip??) inside most Motorola phones. So even though you might not be near a cellular tower, and if airplane mode if off, you should be able to get a GPS signal. But if airplane mode is on, then both the cellular and GPS radios will be turned off.
Basically, the interwebs is pointing to a hardware issue rather then an a software issue. However, I hope a software solution is available.

I'd give $20 for a software solution to this problem. I am an avid hiker. Using a cell phone in Airplane Mode you get 4x, 5x, 6x the battery life. If I can use GPS while in Airplane Mode, I can hike a very long time, but if I'm forced to leave the cell radio on merely to use GPS, the battery won't last a full day's hike. It is ridiculous that we can't (yet) use GPS in Airplane Mode. I have been using ViewRanger offline navigation app for years. I download to the phone before I leave home all of the topo maps that I need for a hike, so I have no need for data when I'm hiking.
Did anyone ever try editing the systems.db file in data/data/com.android.providers.settings/databases/ directory? I can't tell that the guy that wrote that post ever tried it himself.
EDIT: I found here documentation of these two settings.
AIRPLANE_MODE_RADIOS -- A comma separated list of radios that need to be disabled when airplane mode is on.
AIRPLANE_MODE_TOGGLEABLE_RADIOS -- A comma separated list of radios that should to be disabled when airplane mode is on, but can be manually reenabled by the user.

My XT912 is rooted and I have System set to read-write. I tried to use SQLite to edit the value of AIRPLANE_MODE_TOGGLEABLE_RADIOS in the System table of /data/data/com.android.providers.settings/databases/System.db to change it from "bluetooth,wifi,nfc" to "bluetooth,wifi,nfc,gps" but even though I have write permissions to the file, when I tried, I received this error:
Update Failed - Error Code 5. Database is locked.

I went searching for how to edit settings.db and found this thread and this other thread, but I don't fully understand the instructions.
Bottom Line: if this is truly a hardware problem, then editing this file won't fix the problem (but likely won't cause any harm either), but if this is merely a software problem, then this may finally give us GPS use while in Airplane Mode.
Hi Members,
Does anybody know more about the GPS in the HTC Mozart ?
In my old Touch2 i ve got real GPS Modul, the GPS-Fix takes only 1 Minute.
Offline Navigation with Tomtom7.9 was fast and stable and precision. Thats what i need !
Then ive got an Iphone 3GS . It has only AGPS , not a real GPS Modul.
GPS Fix without WIFI or 3GS take about 30 Minutes . The free Navigation runs, but very unprcecision under Trees. Thats a Joke....
Now i have the HTC Mozart. The Telekom Select Navigon Navigation dont start without a DATA Connection via 3GS !
And i found no realy Offline Navigation Software.
Does the HTC Mozart contains a real GPS Modul or only a AGPS Chip like the IPhone ?
Im really angry obout this steps back in the stoneage.
Iv bought an Tomtom XL to navigate. Now iv got 2 Devices and a lot of Cables here in my Car .
Has anybody a better solution for WP7 ?
Nokia Drive, HTC Location... all with no data navigation
Navigon also works without data conection,
just remember to turn on your "location" under settings, then it activates the real gps modul in our mozart.
follow the steps.
the answer to your question is YES.
and follow the steps
1.turn on the gps in settings.
2.turn on the gps in your navigation software(optional if the app has a setting like this)
3.there you go. even without a data connection.
and btw i was curious, does iphone 3gs really a-gps not real gps?
gps
I have now 3 gps in my Mozart... Turn by Turn from gps tuner, which requires data connection so you can download maps on the fly but also you can download them at home via wifi, GPS Navigator from aSpass which is the same, and Nokia Drive that i havent tried yet!
Hi. I use Navigon 4.1 on my HTC Mozart. Did anyone noticed that after using the program for more than 20 mins, the phone turns very hot (i never imagined that a mobile phone can turn this hot). I used it a few times to go to a city 80km and after reaching, when i touched the phone for turning off the navigation, it was really hot. The screen stopped responding to my touch, and I had to cool it in front of the AC for a few mins before it became responsive again. (My guess: the program stresses the processor to near max capacity all the time)
I tried the same distance with nokia drive, and everything was normal. There was only slight heat production (I guess because of the screen turned on for so long), but nothing like when I have navigon on.
Does anyone else has this problem, or am I the only one?
Any reply would be helpful.
Thanks.
