DL30 and GPS

I still notice the gps still takes long to lock in. any suggestions?

Strange, Mines been locking on in no more that 45 seconds, Usually 10 seconds since DJ05...

DLO9 - using leaked 2.2 Rom
My GPS is taking much longer to lock also - i guess its the trade-off for getting 2.2.
The leak 2.2 rom run better than the other Roms I tried.
Sent from my SCH-I500 using XDA App

Odd, mine locks on better than any 2.1 rom and almost instantly.

Oddly enough, got worse on superclean 2.2. With DL09 and superclean (with help from gps status) i was locking within 10-15 seconds, now it takes upwards of 45s-1minute, if it locks at all. A little disappointing, but nothing to make me dump 2.2. Crossing my fingers that it'll get better....

My experience with all 2.2 ROMs so far has been that GPS either locks near-instantly (<15s) or absolutely will not lock at all. It seems to be about a 50/50 crapshoot. If it doesn't work, turning GPS off, waiting a few moments, and then turning it back on and trying again *usually* gets it working.
Granted I haven't tried since jt released the updated recovery, so I'll have to check a few more times and report back.

Try flashing the DJ05 GPS fix that was tested on people with Dl01?

I've long given up on the GPS, I just use my Iphone 3GS that without data connection still locks on really fast.

I tried DL09 when first going to Superclean 1.0. The GPS would lose the signal then regain it. This happened about three times during a hour long route.
Flashed DJ05 last night and tried the GPS again this morning and not once did it lose the signal driving into work.

My gps doesn't WORK AT ALL with DL30 superclean 1.0.

Mine locks in 10 seconds or less running DL30 SuperClean 1.0 with DJ05 radio.

I have been having a problem with GPS on DL30/DL09 also. Here is how I got it to lock today in less than 10 seconds.
1. Download GPS Status from the market.
2. Run GPS Status and let it download the AGPS data.
3. Go into settings>GPS & Sensors>Auto-download AGPS data and set it to never.
4. Close GPS Status and reboot phone with GPS turned on.
5. Once booted, run GPS Status and hopefully you will get almost insta-lock.
6. Open Maps or Navigation and you should be good to go.
Next time you try GPS and it doesnt lock, go back into GPS Status>options>tools>download and manually download the AGPS data then reboot.
Its a pain but its the only way I know of thus far to get "insta-lock" after going Froyo on my phone. I dont use my GPS all that often so this method isnt a big deal for me, but if I relied on GPS daily, I would seriously consider buying a different phone at this point. That or try and get a refurb that has a working GPS like some people here seem to have.

Didn't work for me. installed DJ05 and still nothing :[

Ive had some weird experience with GPS. DI01 My gps was garbage. like 2 mile blue sphere. DJ05 my gps was pretty good... locked accurately but took about 2 minutes. Borked my phone trying to edit some stuff... redid DJ05... GPS didnt work again... did DL09... GPS still didnt work... redid DL09... GPS worked pretty well again... DID DL30... GPS locks nearly instantly and almost perfectly.
It seems like every time I flash I have different results...even when sometimes I'm flashing the same roms from the same sources. I don't really get it... I'm almost in the same areas so it should be consistant.
I always clear all the caches and everything :\

Ive done many different gps tests and here is whats happening...if you try to turn gps on through the notification pulldown...it takes a while. If you turn gps on through settings...location and security...standalone gps...its instant. After turning gps on through settings, it will work from the pulldown every time instantly. Basically it needs to be turned on from settings for the 1st time after a reboot...then the pulldown will be instant. To test this, reboot phone with gps off, when it boots turn gps on from the pulldown...it wont lock...go to settings and turn it off then on...it will lock instantly. Like i said, it seems to need to be turned on through settings initially, then it works instantly any way you use it...hope i helped.

That's strange. I haven't had an issue locking on since DI01. I also love how fantastically loud the Nav directions are now. I agree that gps status can greatly accelerate the locking on process.

Gps?

Hi, I have a rooted eco5 with absoluetly no bloatware. Whenever I use gps it says it cannot find me. Is there anyway to fix that? I've heard of an app that fixes gps, but I don't remember the name. Also I'm sorry for not using the search function, lol

GPS Status?
There is also a mod in the development section that suppose to help fix it.

Thanks for the help. It was gps status.

Yes. Unfortunately the Epic suffers from a few GPS problems under EC05 and we're working on a comprehensive fix for them. However, we're still trying to understand exactly what folks's problems with the GPS are. If you're willing, you could be an incredible help with that.
Has your GPS ever worked prior to EC05? Did it stop working after you upgraded, and hasn't since?
Also, please use GPS Test when testing the GPS as it allows for the easiest understanding of what your current problems are. When using GPS Test, you'll probably want to go into Menu, Settings, and disable the "Keep screen on" option so your screen doesn't shutoff while attempting a fix.
Can you run GPS Test and report what happens? A "good" fix is when the "GPS on" light turns green in 10 seconds or so. A "poor" is when it takes anywhere from 30 seconds to a few minutes to get a fix outdoor in clear skies. "No" fix is when it's unable to get a fix even after 4-5 minutes of good visibility.
If you can report back how GPS Test works, we can debug this a bit further.

I can report on a rooted stock EC05 that GPS has stopped working altogether. Using gps test it never gets a signal. In Maps, the gps icon doesn't even turn on any more. Yes, gps is enabled under settings. This behavior first appeared after I installed Advanced Task Killer and I am not sure if ATK is killing some process that keeps gps from starting. Any ideas or any more info I could provide you to try to help figure it out?

So in GPS Test the "GPS on" light just stays yellow and the GPS icon in the notification bar just blinks? And this is across full reboots (power cycles) too?

It's probably unrelated to ATK. Did it work in EC05 prior to ATK?
We've identified a few issues with the GPS in EC05, one of which is that the GPS can crash and programs are no longer able to use it, but it recovers again after a full power cycle.
What we haven't been able to identify yet are the exact causes of why the GPS doesn't work at all for some folks. Mostly since everyone who has posted in the development thread now have working GPSes, so we no longer can get solid debugging info on them.

Yes, definitely. Are you familiar with running adb commands?
If you can, what would be really helpful would be to enable "USB debugging" on your phone, and reboot (full power cycle) it. Then, as soon as the phone is booted (network is up and it's done "Preparing external SD card"), plug in the USB cable and run on your computer in a command line:
Code:
adb shell "logcat -v time > /sdcard/logcat.txt"
That command shouldn't return immediately, which is what we want. Wait a few seconds, then run GPS Test and wait about 30 seconds or so. Then close GPS Test, and do a Control-C in the "adb shell" terminal which stops the logcat.
Finally, pull "logcat.txt" off your SD card and either attach it here, host it, or email it to me, I'll PM you the details.
Sorry it's a bit complicated, but that's the only way we've been able to get all the necessary information on what the GPS does from boot through a first fix attempt. If you have any questions about running that, feel free to ask.
Thanks!

Hi Mkasick,
so I just rebooted, and fortunately (or unfortunately) gps works. This is how it seems to go for me. It will work for a while on a fresh reboot, but after a while (maybe a day or half day) it fails to start again. When it doesn't work, the gps test behavior you describe is exactly right - icon says "on" and icon light stays yellow. So I assume the ADB logcat file is not meaningful to you if it works right now, correct?
I should also say that from time to time, toggling other radios using the drop down menu from the status bar also fails to work. Wifi specifically will fail to toggle on. Again, this usually happens after the phone is on for a day or so. Glad to hear that ATK is not the likely culprit because installing it has really improved my battery life a lot.
Let me know what I can do to help. You are awesome for working to make this phone better for the rest of us who don't have any coding skills. Should I get that logcat file the next time I notice the gps won't start?

OK, there's a few different issues that can cause that.
One is that the GPS will randomly crash upon exiting or switching away from a GPS-utilizing app, roughly every 1 in 20 times. When it does, the GPS no longer responds to any commands and the GPS icon will stay lit even after you close an app. We're finishing a workaround for this and I'll post it in the next day or two.
The other issue is that the GPS's ephemeris data appears to go stale earlier than it should. Here the GPS appears to work normally, with regard to icons blinking and such, it just can't use any satellites it finds for a few minutes, but if you're outside on a clear day it will eventually fix again. The existing workaround may address this. If you find the GPS won't fix, you can toggle the GPS icon outside of an app and that will download new assistance data which should hopefully help.

Probably not. Actually it might be hard to debug the GPS issues further until I get the crash workaround posted. In the meantime, you can at least discern if the problem is the crash by installing CatLog, and after the GPS demonstrates issues, open the CatLog and look for a line that says:
Code:
E/libgps (####): RIL Request: ERROR 1 (n=110, r=0)
The "n=110" is in particular a good indication of a GPS crash.

I've seen this on occasion too, but not frequently. I haven't had a chance to look into this issue further. It's possible ATK could be responsible here.
Mind running a few days with ATK off just to see if those issues continue to persist?

Thanks! At this point, I'm not sure a logcat will show anything new as long as your GPS does work after reboot. Probably the most useful thing would be to report if the existing workaround helps when your GPS stops working, as long as it's not due to a crash (which CatLog can verify).
I'll try to get that second workaround posted soon. This GPS crashing is annoying and hinders the debugging of other GPS issues.

So neither of the types of crash you describe really apply to what is happening to me. After my gps fails, the icon never comes on. Under the settings menu it says it is enabled, but no application ever gets the icon to come up and there is never any kind of message saying gps signal is lost or unavailable or anything like that. I will try to do what you say with regards to CatLog and send you whatever files seem relevant. ATK will be turned off.
Thanks again!

That could be a crash. If the icon is on when it crashes, it will likely stay on until "Use GPS satellites" is toggled, at which point it will turn off and stay off. If the icon is off when it crashes, then it never comes on again.
The status of the icon doesn't matter as much as the GPS is utterly unresponsive as far as the phone is concerned.

I've just posted the crash workaround. Feel free to flash it (gps_request_sync-EC05.zip in that thread). It's been tested on stock EC05 and SRF 1.1.0, althugh I think it should work on any EC05 ROM.
That alone may resolve your issues, if not, also try the assistance workaround in the same thread and we can go from there.

My GPS was working perfectly for months using the forced cold start. It has had the problem since the update to Froyo.
I tried this one and it is a "fail" as doesn't work at all after a couple of days.

It seems to work at first but I think the "fix" has to do with rebooting the phone, as after a couple of days of uptime the problem of the Epic not using satellites that it sees returns.
I am now trying this one:

My GPS randomly gets no lock without a reboot. This has happened after EC05 update. Now have Bonsai 4.0.1 and Genocide 1.0 kernel. This fix should resolve that right?

Searching for GPS Notifcation

I keep getting the small flashing icon in the bottom right notifcation bar saying "Searching for GPS". I have turned off the GPS capabilities in settings and am still having an issue. Anyone else have this problem? Its sort of annoying when its constantly flashing and I dont want it draining battery or anything.
Lemme know!
Thanks,
Steve

same here. happened when an app need to access location.

Here too, but the GPS doesn't appear to be enabled -- the status just shows that an app wants to use GPS. If set to airplane mode or you've disabled GPS, you won't be wasting battery power.

Hmm thanks for the replys guys, the flashing icon is just annoying, thats all. I guess it doesnt seem to be effecting battery that I know of.
I wonder if theres a way to tell which app is trying to use the GPS?

Open Google Maps, then close it (go to home). It usually stop the searching of GPS sats on my phone with that method.

GPS Randomly Turns Itself On...

Having a weird issue with the GPS on my AT&T LG G2. Phone is unrooted on stock firmware. The GPS icon will randomly appear in the nav bar. Sometimes when I check after that, it will be turned on and I can toggle GPS off. Other times it isn't on by the time I check it. I always leave GPS off for the battery life savings. I've tried doing a factory reset and immediately disabling Google Maps. This seems to keep it from happening, but once I re-enable Maps, it will again start randomly turning on GPS. Even after disabling Maps at this point, it still does it. Only a factory reset then immediately disabling Maps seems to keep my GPS off. Any ideas?
Thanks!

I've noticed this as well. I keep mine on but it location icon started flashing earlier in a phone call.
No clue why that would be.

Had the same issue, it's something called carrier IQ that tracks you without consent. Fortunately you can remove it with root access. There are a couple of threads in the qa and general sections which address this and solving it. Search for them and youll be on your way.

In on Verizon. It wasn't reported to have that and I did run a check, which was clean, just to make sure.

Not abnormal at all. This happens when your device needs to refresh locations for multiple apps to work efficiently. We are not alone. Android thing.

Try disable location reporting in Settings. Also, there's a good chance Google Now! is using to access your whereabouts, unless your really want those cards, turn Google Now! off (voice search still works even after that). Look around Maps settings too, and if you see location sharing or let Google use Maps data or something like that, turned that off too.

This is how I fixed it, too. If you can't figure out how to remove CarrierIQ then you can just disable it after each reboot by going to settings->apps->running->android system->stop.

Hi,
I'm having the opposite problem. When I enable my GPS, after about a minute, it turns off. It used to work fine.
I have a Samsung, but I simply can't find my issue anywhere and I ran across this thread and I'm just praying someone might have some idea what's going on. It's frustrating!

Gps won't grab a lock

So I the only thread I found on this was really old with no resolution so I'm starting a new one.
My gps will show like 0/24 on gps status immediately and not fix any. Earlier I got 2 satellites to fix ad that was all. This is outside in my car with a clear view of the sky. has anyone had any luck fixing gps issues?

Are you using the GPS Status app (developer MobiWIA)? I ask since that app allows you to add all the extra details in the notification bar while the GPS is searching for a lock. If so, have you tried getting a GPS lock in any other app (like Maps)? I can get a lock in all my other apps, as well as other GPS diagnostic app EXCEPT for the one developed by MobiWIA for some reason. I keep it installed though as I like to see the status in the notification bar.
I'd suggest downloading the GPS Status app if you already don't have it (the MobiWIA one), and go into Menu > Tools and click on Manage A-GPS State. Then click on Clear Cached GPS Data. Then click on the button that says Download Additional Files (well, says something similar to that). Then open up a different app and see if you can get a lock. I had to clear my GPS data and download those additional files before I could get a timely lock as well, but now I get a lock within 10 seconds while inside the house. This assumes that you haven't rooted tour phone. If you're rooted, you can do all this (and more) manually. Just clear GPS Cache and Data, and open up /system/etc/gps.conf to add any additional servers to the list, as well as tweak other GPS setting.

ya i tried those before, it's acting even dumber now, the top bad with the gps icon is solid indicating a lock. However any gps status app that I use will show no satellites locked. I get it to lock a couple after sitting there for a while on gps status sometimes though but its really shady

My past g2 did that, I returned it. Got a replacement, afraid to even root this beast.

Well I guess atleast that means it most likely isn't completely hardware related.

Mine (T-Mobile) locks in just a few seconds, even indoors!
I always have data on, so it makes the process even faster (A-GPS makes use of the cellular antennas to acquire a lock faster). It works really well actually. I have at times the GPS off and even then, my location gets pin-pointed very quickly!
Cheers!

I have the GPS lock issue sometimes. What I have found to work for me is I turn airplane mode on let it sit for a second, then turn airplane mode off. By the time airplane mode is off and BT, LTE/CMDA signal notification are coming back to life my GPS has a lock and is working like it should.
YMMV on this, but it does work for me.
