[Q] has anyone encountered issues with CM 11 and gps? - Samsung Galaxy S Relay 4G

i'm not sure if it's me dropping my phone untill the up button stopped working or a rom issue. i've been reading about it, and it seems to be a general problem with CM 11.

Try a different rom.

In the adjacent Development forum, there are at least 4 ROMs other than CM11 (Slim, Omni, Fat (or whatever CM11-variant is called), LiquidSmooth), which is what I think the other poster was talking about.
That said, my wife runs nightly CM11 on her Relay, and we've seen a few times where the GPS signal gets lost for seemingly no reason, manifesting itself as "Signal Lost" in the middle of navigating using Google Maps. It looks like the GPS driver gets into a bad place (not sure if it crashes, or just hangs), as disable/enabling GPS lets it find signal again.
Of course, this only seems to happen when we're out and about navigating, so it's hard to get logs.

I don't have any issues. I am on the 3/06 nightly and I also use GPS Status.
Also, keep in mind that GPS works by locating satillites. Do you have a clear view of the sky?
Also, GPS signal can be spotty and undependable. I remember a case when a faulty antenna on a boat jammed GPS for a 5 mile radius. Also, there are truck drivers out there that are intentionally jamming the GPS devices that their employers have installed in their vehicles.
Even if the signal is temporarily lost, your device should be able to use dead reckoning, cell towers, and wifi to know where you are.

Losing data connection on CM7

I have been keeping up with the updates hopeing each one will fix my problem but not yet. I don't see others with the issue.
I'm running the latest Test4(Test3) using Slayhers stock kernel. Everything works awesome except intermittently I lose connection whether I'm using Wifi or 3G(No 4G in my area). The only way I've found to get it back is reboot.
Is this a widespread issue or just me?
Same issue here. I live in 4G area. Intermintent Data Loss. If i switch to CDMA i get a 3G but CDMA/LTE i get nothing. I had data allday yesterday but none today.
I think the RIL is still being worked out. Bear in mind that this is a Pre Alpha Pre release. Also LTE is something completely new to the world of CM and to American cell phones. I've run CM on 3 different devices and I will tell you that by the time nightlies roll around, it will be near perfect. The CM team won't put their name behind something that is half working, half assed, etc. Be patient.
I had the same problem but now I have a small problem. I have a very fast wifi setup at home but it doesn't like to actually connect to it. Looks like 3G is riding shotgun for a while.

One thing I read about the WIFI is, try turning the WIFI on then reboot with the WIFI on to see if you then connect.
Yeah, I think we'll all be experiencing this until the crew addresses it in a future update. However, it is still a great start. Not a whole lot of major issues, no deal breakers. I'm still using it as my DD.
Definately!!! I love the cm7 build and I'm thankful for all the work. Just wasn't sure if there was an easy fix I had missed.
Thanks all!

Wifi turns off when signal is weak (1.85)

While using the phone in a spot with poor wifi reception, I've noticed the wifi icon completely goes away sometimes. It will then pop back on shortly thereafter. Is this normal behavior when it thinks the wifi signal is completely gone?
I just picked one up yesterday and have been having issues. In my bedroom it will read 2 bars, drop to one, then shut off. Comes back on within seconds. This phone seems to have WiFi issues for a lot of users.

Same problem here, but it also happens when it says i have full bars. I need to enable best wifi performance to fix it. My gsii never had this problem...
This is exactly how mine behaves too. I'm in the room with my router so I normally have full bars (and should) but every once in a while the signal goes away and comes right back 2 seconds later. I've tested it with 2 routers, a linksys running dd-wrt and a d-link one, both have the same results.

International One X has issues too. The newest update 1.85 was supposed to fix some WiFi issues along with other bug fixes, and it doesn't seem to have helped us. Let's not assume they even know what the problem is at this point.

I don't think what I am experiencing is a hardware issue at all. Im not even moving the phone when this happens, and my phone passes the squeeze test. I'm confident this means it has to be software related.
Sent from my HTC One X using xda premium
This is kind of an old/dead thread by now, but I just wanted to share my experience with wifi on the One X.
I'm also having problems, but I'm currently running a nightly (though very stable) build of CM10 on my One X and still have wifi issues. This COULD be hardware related, in that it's just crappy hardware (though it could also be software related if CM10 is built using wifi "code" (not really sure what the correct term for the wifi stuff in the software is ) from the stock software)
I'm sitting at work right now, for example, and every once in a while the wifi will disconnect. When connected it shows 2-3 wifi bars, when it's NOT connected, my wifi network shows up as "not in range" .
same type of thing has happened at my house. I thought my phone was defective so I traded it in for a replacement at best buy. Same issue. Such a shame becuase I really like everything else about this phone and wifi was never an issue on my last HTC device.
kernel changes affect wifi. some of the cm10 builds have known wifi issues.
i would never think of returning a phone because of an experience with a custom rom, since the phone wasn't built to run that rom.
always revert to full stock and see if you still have the issue. also updated ota/ruu are made to fix issues also. at&t rom doesn't have many stock wifi issues, but you can always run into issues with wifi access point incompatibilities.

No problem, I copied titanium from my other phone and restored all his games. Had no idea it had theme choser, gonna go play with some of my themes now
How do I get TWRP on this? I tried the ICS one from the TWRP Installer thread but that didn't work. Installing via Goo Manager is not an option without a network (No compatible Sim).
Just fyi the data even using 2g is giving me random reboots. Otherwise this Rom is freaking fast and smooth. I can't wait till it gains enough stability to run as a daily driver.

I had some reboots without ever inserting a SIM, mostly while restoring apps from SD via titanium pro, so it might not be just data related.
Thanks Erik!
Can't wait until the bugs are worked out to use it as a daily.
Open as per OP request, Thank You.
Awesome update on 4g data, Erikmm! I get to experience JB now. I can hold on to the S3 upgrade for another year. Slim JB on our phone is almost as snappy as JB on S3. If we can fix the wifi, it would be perfecto.
P.s. The small font and icons actually made the phone's screen looked bigger. Feels like I am having an S3.

sweet! i will have to pick this phone back up and use it again.....
Here's something that may go for dev-bug, but...
I wiped my phone and applied the SlimBean R2 installer as well as the SlimGApps. Full factory reset, all that fun. So hopefully no remnants causing these symptoms:
Yesterday I ran Waze (driving/mapping app) on my SlimBean for ~45 minutes without ever getting a GPS lock. Rebooted, tried again for another 30 minutes. No GPS connection.
The GPS Status app says that it's not seeing any satellites at all... so apparently my GPS isn't even trying, as my phone with ICS normally sees 10-12 satellites here. After testing with GPS Status, reflashed SlimBean, reflashed SlimGApps, checked GPS Status again. Still not a single satellite seen. Recovery, flashed YAGF2.zip (Yet Another GPS Fix 2), system, GPS Status, still nothing.
I should probably note that the cell location has been working... Waze was giving guesses as to where I was currently located based on my cell towers. Obviously Wifi location isn't working without Wifi, so the question I have is... are other people using JB actually having GPS satellite locks, or is this another current JB bug? I ask because OP doesn't mention GPS issues, though people reported reboots when GPS tries to take effect. The only GPS thing I did before was making sure that Internal GPS was actually set as the GPS source in Location services, since that wasn't checked... Internal GPS was the only option, but it wasn't checked.
If you need logs or something, let me know what you'd like. Thanks.

Our phone is infamous for its horrible GPS, try this GPS patch and see what happens, http://forum.xda-developers.com/showthread.php?t=1963915
Already had that downloaded. Let's give it a shot, and...
Reboot to recovery, flashing agps.patch.google.build.nossl.twrp.v3.1.zip, reboot to system, GPS Status sees...
Nothing. Still just "Looking for GPS location..." with no Compass (heading stays at 0 degrees) or satellites seen.
One more thing. I know it's been noted that the phone audio only works through the speaker, but music also only comes out through the speaker. At least, plugging into the headphone jack didn't make MortPlayer Audio Books actually come out through the car's sound system, it was still coming out of the speaker.

Read the notes if it doesn't work, let the GPS stay on. Try other methods on the notes.
Note 4:
This works with ANY ROM unless the ROM has aGPS and/or GPS disabled in the code. This happens with CMx nightlies and some betas! I cannot fix this, neither can you.

So... as I'm asking, has anyone actually confirmed that GPS (not location services, but GPS itself) is enabled and working? The build.prop tweak that it suggests (Note 13) doesn't appear to apply, since neither this nor ICS (AOKPm6r5) have the ro.ril.def.agps.mode forced.
Also, note that as I said before, I've let GPS Status or Waze run for going on an hour without it seeing a single satellite... GPS is NOT ENABLED on my JB. Just like Wifi, except it's marked as 'on'. I'm wondering if this is my phone hating life and needing to offer up some logs, or if this is a standard issue. -_-
That being said, when I turned off GPS and just used cell location, I had my first random reboot on second location services call (Yelp's location check). After it finished rebooting, told it to start trying to use GPS again and it went back to just guessing wildly as to my location based on cell towers without ever using GPS (GPS Status never showed in the notification bar, no little coda to signify GPS lock attempt), but also without the reboots, so that was nice.

Problems with GPS: Myth or fact?

I notice that some people have reported their S3's to receive poor GPS signal or that their phones can not lock onto a location at all, even to the point of having to return their phones. This paranoia had also struck me, and I noticed that I began to have problems too. However, I realized that at some point (for me personally) it had nothing to do with the phone. I just wanted to provide some tips as to how to improve GPS or use it more properly.
1. You need a line of sight to the satellites from your phone. That means that being in the middle of midtown Manhattan, you're likely to not get a signal. That also means that if you're in the middle of your living room, don't also expect to magically receive a GPS lock. It just doesn't work that way.
2. While it's controversial whether or not bad weather affects GPS signals, I notice that heavy clouds and poor weather affects my phone's ability to lock on at all.
3. If you're in an area where you can't get a lock (i.e. Midtown Manhattan, etc), turn on Google Location Services. This will always put you within a 500-1000 meter radius of where you are (in which case you would just read a map the old fashioned way).
4. I almost never have a problem locking on a location within 5 seconds while driving on a clear day, outside of the city. If your GPS and Google Navigation still does not work in this situation, you probably really have an issue.
5. During my paranoia, I cleared cache/data for Google Framework Services (warning: this will remove your sync account) and uninstalled updates to Maps and reinstalled. That may help if you've been flashing back and forth between roms.
Hope these simple tips might help some people out.
I don't know if it's because I leave GPS and Location services on all the time but I've never had an issue with GPS lock with this phone whether I'm in the burbs or in a city.
Yesterday I was in open line of site in Fitchburg MA, I had the GPS on for 20 minutes as I was scrambling for and event. It just would not lock at all. When I do get a lock. Yesterday same day driving 2 hours to Cape Cod (105 miles of open space) it would lock work good for a couple minutes then lag for a few seconds to minutes and not move then just jump and update. (Says GPS signal lost.) Sometimes it would then put me on side streets and struggle for find that I was still on 495 South. It did this when whole way. I knew where I was going so it wasn't a problem but there is something up and I am interested in finding out what. BTW this started after the first OTA update from Verizon.
If you have problems with gps get a replacement phone.

Tough to sign onto wifi on the highway
Even when I was in line of sight and with wifi on. My s3 wouldn't get a gps signal or lock on. My wife's Rezound did. So, I called Verizon and they sent me a replacement and now everything is fine. It was the hardware in my first one that was the problem.

Exact same issue with me. I haven't tried it bout lately because it pissed me off. I started using GPS status and toolbox and beginning to calibrate and update things. Hopefully its better now. Unfortunately, I cant get a replacement because I bought the phone off contract on eBay (just like I always do).

You don't have to. For some reason enabling WiFi alone will improve the GPS's ability to get a lock. Though this isn't always the case, its one of the first things I do when I have trouble getting a lock.

Yeah I don't understand it also but when I flash a new ROM, I would go to google maps. At that time I would not get a GPS lock until I turn on Wifi. GPS status app also helps with a good GPS lock.

It's getting a rough location estimate from access points when your turn WiFi on. WiFi location doesn't have anything to do with GPS. This will only work if you're by access points.
I've had problems since day one of owning this phone. I've owned a droid 1 and droid 3. My og droid honestly never failed to lock almost instantly whether in my house or on the road. Its a shame to get such a new phone and have issues like this. Multiple threads show many users are having the same issues. I've tried fixes, clearing caches, flashing new roms and nothing.

All wifi is used for is helping finding a rough location by send info through Verizon about access points nearby. Turning it doesn't make the internal gps work "better" in regards to seeing satellites it just helps Google get a fix on the phone faster

Same, its probably the rom they're on. Even on 4.2.1 I get GPS though (not inside, but I can on TW roms).
OP: I can get a lock inside my living room
My GPS locks 20% of the time...outside on a clear day in Cali. Not sure what to do anymore. I've tried everything I read on here but returning it. I have a feeling they'll just give me a used refurbished phone so I hesitate to do it.
I can safely say that S3 gps is the best I've had out of all the smartphones I used. I am frequently in midtown Manhattan and it locks there within 10 seconds, and it works in my livingroom
Every time I load a new Rom I open up gps status toolbox get a lock instantly then open maps to locate me then I never have any trouble after that at all.

[Q] GPS Issues on all ROMS

Hello all,
I'm having issues getting GPS to lock on every rom. Be it AOSP or TW based, my GPS has trouble locking and updating. Often times in Google Maps and Waze it looks as though the arrow is facing 90 degrees in the opposite direction. Another problem is that after the GPS locks, it then does not update as frequently as it should causing the arrow to stay in one place on Maps and it can take minutes to update with your new position.
Has anyone else been experiencing this?
My baseband version is VRUCML1
And my location settings have been set for high accuracy.
Edit: This issue has been fixed thanks to TheHobbyist

Hey there. I had gps issues before as well. I tried literally everything on the software end of things with no luck. However, I took the back off of my s3, tightened the screws (you need a special small screwdriver), booted back up, and viola!
I know it sounds odd, but trust me on this one and give it a go ☺

Having a very similar issue. I'll try the screw fix, I suppose, but I feel that the problem is more with updating than locking, leading me to believe that it may be a software problem.
Please post if you have found a solution! Any help would be greatly appreciated!
I swear by the screw fix. After your GPS is fixed, use GPS STATUS free on the play store for optimal gps performance

I'm glad to hear yet another success story! :good:
Regarding a technical explanation, the gps does rely on signal reception (gps signal reception) and as such, it makes use of an antennae that is incorporated into the body of the phone. When the screws are tight, the contact between the gps and the antennae it uses is better and you get better gps reception.
(This is my theory)
I don't make cell phones, but I work with electronics hardware a lot. In my case, the screws were loose because my kid is always throwing my phone across the room =)
If you ever are browsing xda and see an s3 owner with gps issues, please take the time to share this fix with them! :good:
