GPS turns off during use

Hello guys,
with some of the latest firmwares (M2/especially M5) I'm experiencing a new bug - namely that the GPS simply turns off after 3 minutes of usage. I'm testing this with applications like Google Navigation or GPS Test and after a few minutes the GPS Symbol in the notification bar just disappears and the apps don't receive any position/data update.
Any ideas?
greetings
Alex

check your auto task killer

I didn't install any... I also tried to turn off almost every service running but the behaviour stays the same.
interestingly the app that uses the GPS stays open

Same happened to me. I couldn't solve it so a reflash seems to have done the trick. Can't be to sure since I haven't tested it that much so far.

I take that back. It's happening again and I can't understand why. Happens with all apps, NDrive, Navigon, GPS Status and GPS Test.
Did you find a solution?

darn...
first reflashing helped, but happens again now exactly as you describe...
It's very annoying because beside this GPS works quite well

now why would gps freeez ?

heya fellas
now here's something crazy going on with my SGS and the gps
started gps from the android power widget bar boom its on
start google maps from the menu and it starts
the map loads almost instantly from last position where i tried the gps
click on menu and choose My Location
phone says waiting for location followed by your current location is temporarily unavailable
so i goto the lbstest to check on how the gps is doing by *#*#1472365#*#*
goto Get position test and nothing shows up for 30-60 seconds
so i click back to homescreen to disable gps and reactivate it only to find out gps not going off on the notification bar and the only way to bring it to life is by a phone restart
happened 4-5 times and after the 6th restart i gave up
whats causing the gps to act like that ?
iv searched around and couldn't find a similar problem with other users
today after work on my way back home i said lets try it again but without the google maps
so gps on -- lbstest on -- get position -- and boom after 16 secs i have 8-11 sats ( mainly stood there with 10 sats for almost 30 secs with mainly high readings of 31 dBHz and up thru-out the list ) with reading from 19 to 41 dBHz as min and max
waited 60 to 120 secs and no lock just showing me that nice long list of sats
now im wondering what in gods name is going on
1. could it be launcher pro ? last installed app ( im loving the whole experiance, much faster than TWlauncher unfortunatly using homeswitcher whenever i need to check for kies updates, launcher pro wont start the mtp app )
2. could it be voodoo V4 lag fix (using the update.zip method) i so doubt a lagfix can do such a crazy thing to gps
someone tell me im not the only one with this problem

next time the GPS "freeze"
just turn off the phone, turn it back on, and it'll work again
from personal experience, it only goes into permanent sleep when it has been iddle for more than 12 hours give or take
so the best prevention, is simply to turn off GPS when you are not using it, rather than keep it ON all the time

i never keep it on , thats the problem
only before using google maps or any thing that requires gps
well just like i said a restart does solve the problem temporarily but keeps on doing that

how soon does the GPS freezes again after you reboot the phone
does it only freeze after you don't use it for a while?

Its totally random, either immediately after starting gps or after switching it on/off 2-3 times
I guess a hard reset could help at this point, totally useless now, can't get a lock no matter what I do

[Q] GPS Question

Like many other Captivators I've tried all the GPS fixes and nothing really ever worked very well. I flashed Apex 10.1, changed SUPL settings to the Google server like I always do, but still no real improvement. A few days days ago I thought I'd screw around with the General settings and try out the different Operation Modes (I've always had it on MSBASED). None of them did much except the Standalone option. Now my GPS works almost perfectly with gmaps. I get 15ft accuracy and it doesn't bounce around like it used to and I get an initial lock within about 10-20secs. I've been trying it out every day since Monday to make sure its not a fluke and doesn't degrade over time, but so far its been great.
This kind of goes against everything I've read in these GPS posts since last year. Is my phone just weird or has anyone noticed this also?

Have you ever tried Heathens GPS fix? Search it out, after installing change a few settings in lbstest.
Operation mode MSASSISTED
Accuracy 40
Then delete data.
Now, download GPS status from the market. Let it dl it's data. Then check maps. I had locks down to 5ft in less than 20 seconds, maintained 5ft lock at 60 mph.

Just tried it out but no dice. It was really strange when I used MSASSISTED though. It got the first reading for the satellites then GPS would turn itself off. Tried it out with GPS Test and still did the same thing. Tried it with MSBASED and STANDALONE and GPS stayed on and it jumped between 5 and 15m, 7-9sats.

Troubles OTA Update 4.19.401.11

Hi guys.
I am a french guy with an european One with the Soft version 4.19.401.11.
I have 2 issues since this update:
- with the date & time set on automatic, my One is in late. In firt, it was few minutes (7 or 9). Now, it's in late of 31 min.
I have to disable the automatic time and set it manualy.
- the screen timeout doesn't work someting (maybe there is a link with my time issue). Sometimes, the sreen stays "on" and I have to shut it off myself.
For exemple, when I charge the phone and I remove the power adapter, my screen stay "on" and if I don't take care, it use my battery.
I made 3 or 4 reset and the trouble is still here.
Anyone have a solution please?
Thanks a lot.

Use an app like GSAM battery monitor to find out if you have any wakelocks. I sometimes have a similar problem with the screen staying on if I hav my phone on auto-standby, Maybe try another setting

Thanks yoda1998, I'll try this app.

I found something today: http://www.droid-life.com/2014/05/2...ve-amount-of-battery-google-working-on-a-fix/
I uninstalled the last version of Hangouts for installaling the stock one and I'm testing now...

GPS behavior - normal after reboot or from cold?

Can someone help me confirm if this is normal GPS behavior? I'm rooted on ANG3 with the latest maps 9.2.0.
If I start maps after a reboot, or when GPS is "cold" like using for the first time in the morning, the GPS indicator in the status bar will come on for a second or two, then just turn off - at which time maps stops updating my location. It does this same behavior with other GPS apps, including navigation. I found out if I wait like 10 seconds, the GPS status bar indicator comes back on and remains on - from then on behaving normally. After that, I can close maps, reopen, use navigation, use GPS status or GPS test apps, etc., all normally.
I had initially been closing whatever GPS app I was using and reopening when this happened, and the problems kept repeating...but if I found out if I just wait for those 10 seconds or so, then the problem is completely resolved until the next reboot or cold start (like if I wait 10 hours to use a GPS app again).
So do other people have that same GPS behavior immediately after a reboot or from a cold GPS start - where GPS only comes on for a second or two, then turns off for 10 seconds or so, then comes back on and will remain on and work normally?
If not, any idea what the problem might be? I've tried clearing cache of gps apps and clearing dalvik cache...but maybe this is normal behavior?

No problems with my gps here, i personally keep it turned off until i need to though so not sure if that factors in to it, you may need to take it in because that sounds like a possible hardware issue. Have you tried a factory reset/reflashing?

Thanks for the reply. Yeah, I wonder if leaving your gps off mostly, and only turning it on when needed might affect the behavior I'm talking about. I haven't tried a factory reset yet...was hoping to avoid that, and especially didn't want to do it if others have the same gps behavior. Maybe someone else who leaves gps enabled can test this out by rebooting and opening maps?

Hate to be the bearer of bad news and all that, but i feel like if it was that big of an issue there would be more people posting about it. I know you don't want to but a factory reset fixes most issues, i may be wrong though so feel free to wait it out and see if someone has a solution :/

I had a chance to check the behavior of my wife's Galaxy Alpha (uprooted). Actually, her gps seems to act similarly except that the period of time it spontaneously turns off is more like 5 seconds instead of 10. But that leading me to think what I'm seeing is normal. I'd still appreciate some confirmation though, so if someone could:
1. Turn on gps
2. Reboot
3. Open maps and observe the gps indicator in the status bar for about 30 seconds
4. Report if the indicator disappears during that time and for how long

Thanks for the suggestions. I'm not sure what's going on, because I haven't really tweaked anything but it's now acting normal most of the time even after fresh reboots. But I did still replicate the behavior several times on my wife's stock Galaxy Alpha. Anyway, I'm going to be keeping my eye on it and trying to see if I can figure out what variables seem to be causing the behavior. If anyone else ever notices this though, please post.

Just an update: the behavior had seemed to fix itself, but this was while I was traveling out of town for the holidays. Back home now, and the behavior returned. Since I've replicated this with my wife's stock Galaxy Alpha, I'm wondering if this has something to do with my home location being set in maps...or? Seems weird that it resolved while traveling but continues when back home. Really surprised nobody else has noticed this. Maybe it's something specific to my home location? Guess I will keep checking on it and report back if I figure anything further out.
