Why did GPS accuracy take a nose dive after Maps-v6? - Nexus 5 Q&A, Help & Troubleshooting

It's like they changed all the low level code that deals with the actual signal.
There doesn't appear to be any filtering or averaging going on anymore, which is causing my readout to bounce around by 15meters or so all the time. It didn't used to do this on older maps versions.
When I'm sitting at stoplights it says...turn left...continue straight...turn right...turn right...in 500 feet, turn make a U-turn...
It does this as my location constantly changes.
Does anyone else experience this? What to do about it?

Revert to an older version.

Nope, I surely don't have the same issues as you.

Gps has been.working super accurate for me. Best is to.use high accuracy setting

Maps doesn't control the GPS or anything, the system does lol..

thanks guys. have high accuracy mode on. Running custom ROM (Paranoid) and Kernel. Is anyone else doing same as me?

Maybe i have the same problem when change direction, forma example turn right or turn left is slow. Anyway i will upload a video ti understand.
With androits can you share your GPS lock?
This is mine outdoor.... For me is very poor my signal but i dont know if There are a device that can get more SNR and more satellities.

Mine is been the same before the the new maps. It's never been great, but good enough. What annoys me the most is that EVERYtime I open navigation I get a message saying that i can improve accuracy if I enable wifi and then have to choose ignore or settings... Used to only do this once.

see my videos
navigation is exact like me?
is normal? or i can get rma?

GPS on Raphael

Tested it out today, counted from when I opened OCN8 and it took exactly 30 seconds to get a fix. Perfectly acceptable if you ask me, especially seeing as I'll only use it for long drives.
great to know man
Thx for sharing
Did you try any button mapping software?
With or with out A-GPS??

With A-GPS, I don't think you can turn it off.
Only one GPS setting: Enable AGPS: Checkbox.
No, I haven't done any button mapping to the other person who asked.
Is the device as fast as shown in unwired videos?

Yep, 26 seconds for me using Garmin.
And yes, mine is as fast as the videos. Definitely an improvement over the Diamond, despite the Diamond's speed improvements with recent cooked ROM's.
Amazing what a bit of extra RAM will do...
Great, thanks for the info
Since you're using Garmin
I've always found it's notifications to be quite lower than other GPS s/w even when placing an attention tone prior
Is it any louder on the Raph speakers in comparison with Kaiser?

You know what, I've not managed to get a GPS fix using Copilot 7 or Google Maps.
Strange. Very quick for me too.

Make sure to download QuickGPS before you use those programs, that may be your issue.

Fast like, TF3D being fast? Check this video out, AT&T model, 100% out of the box and not 1 tweak applied:

Now with tweaks, it's unreal.
Nope, still not working.
Have you tried GpsTest?

Oh, no...what's that? Is it something built in or is it an app I have to install?
EDIT:
Copilot has a GPS Status thing built in. Looks like I can only see one satellite. Kind of weird.

Are you outside or inside some building?
GPS works fine for me in both Google Maps and TomTom Navigator. Indoors is not so great, but whilst in a car it was fine all the way home on a 30 minute journey!

I'm in my house, my Kaiser right next to it is working fine.
GPS isn't supposed to work indoors... If you need it indoors, you may also need to be living in a psychiatric ward. :\
I got full signal in front of my house according to OCN8's little GPS status bar, for those who care.
As mentioned earlier, QuickGPS will help (hopefully as it has been useless for me since Kaiser WM6.1 ROMs started to be cooked)
BUT
You need to give it time first to aquire GPS fix alone THEN go back to your PC to download the QuickGPS data
To make sure you have everything afterwards successful,
reboot your PDA and see if you can aquire a faster fix.
You can test with GPSTest attached here.
If it didn't solve your problem, check with other fellow Raph holder their Radio versions and yours.
If you are to flash, do not forget to HardSPL your device.
Good luck and give us more feedback

@fireblade63
I'd say the notification volume in Garmin is about the same as it is in the Kaiser, so I agree - it's certainly not the loudest, but I'm someone who likes the Sat-Nav turned down a bit anyway. I hate having the things shouting at me, especially if there are other people in the car who I'm trying to talk to.
My father-in-law, on the other hand, could never cope with the Garmin / Raphael combination because he turns his TomTom XL up to full volume, which drives me mental on the odd occasion I have to experience it!
So, no, the Raphael is no louder as far as I can tell.

Do not compare your CRAP with Nexus S.
We got excellent GPS.

If by "excellent GPS" you mean, that its GPS will show you as moving wildly about between 100m when you're stood perfectly still. Yes, you're right.
It's bad. The best lock I've had is to only 10m, and something needs damping down, because one of the accelerometers goes crazy - use GPS status to see - and refuses to settle, and that affects your position drastically.
I find the GPS to be very good. Better than in the Galaxy S I used previously. These phones will never meet the degree of accuracy found in dedicated devices, they also rely on a data connection, but it was good enough that my TomTom got donated as i don't want to have too many devices in the car.
Oops sorry

[Q] Component missing i9001

Hey guys! I just bought myself an I9001 Galaxy S Plus from someone (second hand)... It's my first smartphone so i think i've been busted.
The phone seemed to work well, and everything was ok. But when I try to use the GPS (without internet connection), it does'n seem to find any server. I've changed some different ROMs with different Kernels, but it still can't reach any server.
I forgot to mention that with some ROMs the signal level is very oscillating...
Today i was looking at the phone and observed that there is a hole just above the battery where some component, like an antenna or something is missing. I don't know what component is that...
I think that the missing component is the one in te next picture. But what is its name and role? Instead of it, at my phone, there's a soildered wire... This trick was made to mask other issues of the phone? (if i replace the missing component the phone might have problems?)
I'll attach the photos, may be you can help me. Thanks!!!
Does anybody know?

I think it's a Connector coaxial, a micro miniature form of RF coaxial connector. Look at one i marked with an arrow.. You can replace that part from samsung service center
Best of luck.
The details:
Design LOC: RFS100
SEC CODE: 3705-001731
Description: CONNECTOR-COAXIAL
thank you!
but that's the reason why my gps doesn't work?
or that's the reason why the signal level is very oscillating when i'm using some custom ROMs?
do I need it, or i can live without ?

May be. Not sure..
I used to have a i9000B wich is basicaly the same device.
THE GPS signal simply sucks, it was so bad that sometimes it took 2 minutes to lock in open field, with some roms it got better with other even worse.
I used GPS AIDS with that device an app that was developed just to try to solve this particular device problem at that time. look it up, maybe it can help a little bit, but i thing this device will never get a high speed gps lock.

I know that its GPS sucks, but mine effectively sees nothing. no server
Am i blind, or my antenna is missing completely?
No. Sorry, the antenna is there. I don't know what my problem is with the GPS.
Doesn't seem like there is anything missing. GPS on this was really bad. I never got a GPS signal.

[Q] GPS facing a bit off

Hey all!
I'm mainly wondering where the cause of the problem would lie, kernel, ROM or perhaps something else, but if any solutions to the problem is ofc greatly appreciated!
On to the problem:
When I start any app that uses my GPS to locate me (ingress, google maps) my location is perfect but my facing seems to be random, at times its good but most of the time its either 90 degrees off for 180 degrees off... So in other words it would look like I´m facing the exact wrong way or to the side.
I'm currently running with CM NIGHTLY 11-20131229 hammerhead.
No custom kernel or anything else modded more then xposed framework with greenify

Thanks for the reply, I tried it a bit in Ingress and it did not seem to fix itself for about 2 min ish that I looked on it.... Any idea on how long it takes for your to adjust?

When on foot, on my bicycle, and in the car, it reads which way I'm facing after I've traveled about 50 yards.
Have you ever tried one of those supposed gps-boosting apps?

what have you tried so far to fix it?
I would recommend a GPS calibration app, can't recommend any though. also making sure your the setting set to GPS, WiFi and Moible Network. That's gonna give you the best accuracy
