[Q] GPS acting crazy

If you're locked into as many as ten satellites is there any reason to have erratic GPS performance?
I got a refurbished S3 from Sprint and the GPS is a freaking mess. I can be standing perfectly still and the map starts moving around erratically, sometimes even straight backwards. Other times I'll be driving and it will show me on a totally different street or moving in a totally wrong direction. Sometimes this is going on when I'm locked into as many as ten satellites.
Shouldn't that be enough to get a good fix? Does this suggest that the GPS receiver is working well but there is a software problem? Or is this a hardware problem that can't be fixed?
I reset/downloaded agps data with GPS Status, I've tried TopNTP and I've tightened every visible screw. Nothing has helped. I also can't get a fix indoors like I used to be able to with my original S3.
Any suggestions on other things I can try to make my GPS work or is this a hardware problem that can't be fixed?
This is the fourth or fifth refurbished Android phone I've received from Sprint over the years and not a single one has worked right. It's like they don't ever really address the reported problem. They just factory reset the phone, give it a cosmetic facelift and then ship it back out without any testing.

What Rom are you using ? Did it behave like this before rooting ?

I'm totally stock 4.3, just rooted. I rooted it pretty soon after I got it so I don't remember if it was like this right off the bat. I believe it was.
Weird thing is that today I tried turning of Google location services and that seemed to help a lot. It doesn't seem to be getting a lock while indoors but when I'm driving around I'm not getting the erratic map behavior I had before. No idea if it will work for long, there have been a few other times when I thought I fixed the problem and it came right back.
I know on my previous phone I had Google location services on and it worked like a charm. Anyone have an idea why turning location services off helps and what I can do to make GPS work right with location services off?
Any real downside to keeping location services off?

I've always kept it on. But if your Stock rooted, and have that big an issue with GPS. I would almost be inclined to say it's a hardware issue. You could always Nand, and flash a coherent Rom. Just to see if it resolves the issue.
TEAM MiK MikROMs Since 3/13/11

After driving extensively with Google location services turned off I did not experience any more erratic behavior. Problem solved but I'd like to have location services on.
Tonight I turned location services back on and it still seems to be working fine with no erratic behavior. I haven't given this as thorough of a test but I'm optimistic.
I have no idea why turning location services off fixed things but if anyone comes across this thread looking for a solution to GPS problems try turning Google location services off and see if that helps. It looks to have done the trick for me.

[Q] GPS Problems

If I try to navigate from the Zenwatch, the phone brings up google navigate even if the phone is sleeping. I would think that might be an issue in a pocket, but that's not the biggest issue.
The destination seems to get set correctly but neither the phone or the watch continues to navigate. They both seem to lock up.
Subsequently any other Nav app (I hope Waze gets Wear support soon) is unable to navigate as they are unable to get GPS lock. Looking at other GPS helper apps shows zero sats in range. Stopping/Restarting location services doesn't solve the problem. Only resetting the phone does.
Maybe it's just me. Sprint HTC One Max, stock. Anybody else?

I noticed this the other day when I was testing out navigation for fun. Once I took my phone out of my pocket, it seemed like it was able to get a lock again and things went more smoothly. I know gps can be a bit sensitive sometimes and maybe having it right next to your leg like that blocks the signal?

When the problem (GPS lockup) manifests there is nothing that will get it going other than a phone reset. I normally have my phone in a holder high on my dash where gets good reception, but when it gets in that state, not even one satellite shows a hint of a signal. Today I even made sure to stand outside holding my phone up in clear sky just to be sure.
Even if I don't access nav Google maps or Micro Maps from the watch it still locks up at some unknown point. I normally keep GPS on all of the time and have a number of apps that store locations from time-to-time. When I get in my car, Waze automatically starts but I can't get any sat signals until I reset my phone.
I'm experimenting with a theory that another member brought up in a different thread that there may be a connection with using a watch face that also includes weather and the number of GPS requests it makes. I've changed to the basic face that is in all of the marketing photos and continuing to test. I guess my next step will be to leave the watch at home :crying: to make sure that something wonky hasn't happened with the phone itself.
Are there any other frequent GPS users out there that can confirm or haven't experienced the problem? It doesn't seem to matter if you use the nav functionality on the watch.

The updates this morning seem to have fixed the problem.

GPS after Lollipop

Is anybody else having GPS issues after updating to lollipop? I am using the app GPS Status and it does not connect to satellites according to it? It shows 21 satellites but connects to none. Is there anything I can do?

I'm having similar issues. Maps seems to still grab a signal however. Over the past two days it seems to have gotten better, but the sensitivity seems to have taken a nose dive.

I have used gps this morning and it worked. I didn't check how many satellites its connected to but it seemed to work ok.

Same problem here, GPS had been acting up recently, but I tried it on the way to work this morning and couldn't get anything. Tried turning GPS on and off and rebooting the phone, still nothing. I have no idea what else to try. It's set to high accuracy mode, not many other settings to change.

I discovered a workaround, although it's an annoying one, but if I switch my phone to CDMA only so that it's forced to use 3G, GPS works just fine. Switching back to LTE though it will not lock onto any satellites.

Tried it out this morning and had no issues when on LTE

What I felt is that there is some slight gps lag, like if I make a turn, gps will show I made the turn a couple of seconds later.
But no issues with gps lock while on LTE.

Yeah, I saw this under KitKat and now under Lollipop. Not sure if it's a Note 4 GPS issue or a mapping app issue, though - I was going to try some tests using a Garmin unit and GPS Test Plus on the Note 4, both displaying actual Lat/Long coordinates to compare the two (though not sure how well that will work given general GPS inaccuracies). At any rate, there is clearly some lag in the map position display. I don't have any acquisition or lock issues.

Ended up doing a different test. The consistent lag I have been seeing is with Google Maps. Today I did a 46-mile drive on freeways, highways, & surface streets and used Sygic mapping app. Sygic was dead-on the entire trip, showing the vehicle in intersections, etc. at the time the car was there - Google Maps would have been significantly behind. So my GPS seems to be working just fine but there is an issue with Google Maps. And GPS stayed locked-on the entire trip.

Yes I'm having problems too. I always use Google Maps Navigation and since the update it will randomly say "GPS signal lost" while driving. I am on the latest BOB7 stock rooted, fully updated profile and PRL.

Anyone having issues with Waze and GPS?

Having issues with waze app and GPS. I've always had GPS issues with all of the Note series, so this doesn't surprise me. But this time around it seems like waze is the only one acting oddly. Specifically when I'm on a guided route waze intermittently sees me in a different area, most commonly when I'm on the highway it will see me on a side street running parallel to the highway. So then it thinks I'm off course and routes me back onto the highway or another direction, but I'm still on the highway. Sometimes I think it even sees me traveling a different direction, many times I'll be on the highway and it will want me to do 2 u-turns, changing directions twice but ending up going the same way as before. I also see the arrow icon representing my car on the map will constantly turn as if waze can't tell which direction I'm traveling.
My first thought is faulty GPS. I've ran Google Maps and it seems pretty solid, with none of those errors, but I'll have to test some more. Just wanted to see if anyone else got this? I may switch back to an older APK and try that as well.

No problems here. I noticed the 7's gps is way faster than my note 4 too. It finds my location on a second. My note 4 would take 5 to 10 seconds to lock in

I am having the same issue with Waze on my Note 7. It thinks i have turned onto a side road so it trys to redirect me to the the road im acually on. Its seems to think im about 30 to 50 feet to the right on the screen no matter what direction on the compass i am going.
Sent from my SM-N930P using Tapatalk

I've been having an issue when I'm stopped at the light, and the screen will start to spin around. It's like Waze forgot which way I was going so turns me around & recalculates the route...repeat.
Improvement over my Note 3 which regularly couldn't find a GPS signal or lost it in the middle of driving somewhere.

Were issue
I have been having issues also bit but only with the voice guidance. I get hazard alerts but that's it. Any thoughts on this?

waze always seemed to place me about 50 feet to the right of the road. It spent a lot of time recalculating on/off ramps when it didn't think I was driving through corn fields. I figured it was just a calibration issue with my device and didn't do anything about it before swapping it for a non-exploding phone.

I had no problem with my recalled Note 7. The replacement is messing up with waze. All the symptoms listed above are happening. Ugh

Hmm..that's not good..I still need to get mine replaced...

No GPS issues with Waze on my note 7. I use it daily and mine is a replacement. The only issue im having with Waze is the voice commands. The three finger option and waving just don't do anything! Anyone have an issue with that? I want my one eyed purple monster back!

IDK, I haven't checked on my Note 7 yet, I find this a bit funny though, Most GPS's should be accurate to within something like 5 feet, They are really accurate to within fractions of an inch but the Government and Military makes sure that the firmware on the GPS's for use by the general public are locked out of that level of accuracy. It really is a joke these days.

Do a search and in the search box enter in 2##2 to enable debugging and then enter in ##@rawgps and it will show you what your phone is reporting as the actual raw GPS via a yellow arrow. Send in a debug log on the very bottom of the settings every day. Could be possible that Waze can make adjustments to the note 7. I personally haven't noticed any issues with either phone yet, I do also keep my phone in a case and in a windshield car holder with a good view of the sky. When I ran the app for the first time though I did have to toggle location off and on to get Waze to get a GPS lock.

I returned my replacement unit and got another Note 7. No change. Waze is still showing me taking exits and being on the side road before correcting. Very annoying and the constant recalculate and accompanying chime make it onerous to use. Google maps seem to be fine. I submitted a ticket to waze as well as sending log files. I hope a fix comes soon. I need my alerts when commuting.

I fixed my Wave problems. Apparently when you do the smart switch transfer, it transfers some settings or calibrations maybe. I went into phone settings, application, waze, long press storage, clear cache, clear data. Then Uninstaller and re-download and install waze. Mine has been rock solid since doing this. Hope it works for you too.

GPS issues

So I have noticed when I am going on long trips that my GPS keeps bugging out on google maps. At first I thought it was maps being weird but now I'm starting to think its the GPS in the phone itself. I'll be driving down the highway and it will suddenly start pointing the other direction like i just made a turn. After about a tenth to a quarter of a mile it will correct itself. Over the course of a 200 mile trip it did this every few minutes. Sometimes it would think that I had pulled off the offramp when I was still cruising highway speeds. This and the camera issues are making me seriously consider selling this phone and getting something different...

In Google maps click your location (little blue dot), then in the bottom left hand side click calibrate compass. I was having the exact same issue until I did this.

I have tried doing the calibration and it still wont get better than "low" accuracy. Do you get better than low?

Mines medium right now. I remember when I was having issues it showed low too. I had to get out of my car and do the compass calibration again as for some reason it wouldn't move off of low every time I tried in my car.

Yeah it's terrible. Hoping someone else has some fixes

Same annoying gps issues here as well

Just happened today for the first time. No clouds or building, I was out in the open. Marker flipped 180° 3-4 times while I approached a stoplight... hard to know which way to turn.
Makes me think this might be related to the recent 10.0.6 update?

Yes, that is exactly my lips around a hundred and eighty degrees numerous times. Takes forever for it to get oriented and it still sometimes gets off the kilter. I have noticed this since 10. 0.4

The first time I noticed this issue was November the 8th when I was driving north for 3 hours. It was obviously happening where it would do that marker flipping around. This last sunday i went on another trip and was still noticing the issue often. It even caused me problems when I was walking around downtown Kansas City trying to find a venue. I had to ask somebody to point me in the right direction because the thing couldn't decide where i needed to go. I have reached out to the oneplus support and i'm waiting for further instructions from them. ... here... ill copy paste the email.

Will this just completely wipe my phone if i follow the instructions? I seriously don't want to do that especially if it might not even fix anything.

No, it will not wipe the phone unless you select that option to wipe data or factory reset.

Well i will tell it to just wipe the cache... i am pretty positive whoever was handling the support just gave me instructions to wipe the whole phone though. lol. im not doing that.
Edit:
Wow... so frustrating... When I tried to do those functions the thing asked for a password. It wasn't my pin or my normal password i use. I have no idea what it was asking for but it gave a forgot password option to reset the phone. I reset the phone.
Also... its that easy to reset this phone?

Ok... Well after resetting my phone completely booted up, installed the latest patches and now when I check the accuracy in the maps it checks out high. Hopefully it stays that way.

So, did you end up losing all your data?

I was never root in the first place. All my data is in the google cloud. I just had to go through the annoyance of setting up all my settings and icons since they didn't stick.

Well I know it's not 7T, but I had horrible GPS on the 6T and 7 Pro models both. Neither had ok accuracy, no matter what I did. It would lose GPS signal on street, in car, on foot. OnePlus is just super horrible at GPS, and I have no clue why. Like why it is not acknowledged and why they won't fix it.
My recommendation is to try a reboot and/or use Google Maps when this happens. I am a fan of Waze, I prefer it much over Maps (speed limits). But in Waze and any other 3rd party GPS app - it struggles to find me way more than Maps. That said, your GPS won't magically fix itself in Maps. It will be just a tiny teeny bit better. So like.. from super horrible bad it will go to christ this is a horrible gps. It may still help in a pinch.

Interesting, thank you, I will try that.
I mean in my testing, I actually put different phones next to each other and tested GPS Signal strength.
The 7 Pro basically has a much worse signal than any other phone I tested. It's dark orange/red. Every other phone is at least yellow.
Just install "GPS Status" from Play Store, put your phone besides whatever other phone and prepare to get shocked.

Hello,
Posting this in case others are still searching for a gps accuracy fix on the Oneplus 7t phone.
I may have found a workaround for the gps accuracy issues on the 7t. Fwiw, I'm using the Verizon version, on a HD1905, with the latest March update 10.0.0.HD65AA. I was experiencing all the same issues, and sadly the March update didn't seem to make any improvement. I've only had the phone for a few days, and was very disappointed w/ the gps performance. Tried everything including wiping the phone clean (I didn't realize the gps was wonky until I spent a couple days migrating everything over), and nothing worked -- it would immediately boot and have wildly wrong gps location, or the lock would seem to phase in an out. If it wasn't for the shelter in place order, I probably would have returned it.
After much trial and error, I found a workaround that seems to work. Even tested on our walk around today with Gaia and it correctly tracked our path.
1) put phone into airplane mode
2) reboot, and leave in airplane mode after reboot
3) run google maps, wait for lock, should be accurate
4) turn off airplane mode
5) test gps -- it should work better
If you reboot while normal networking is enabled, the gps would fail every time -- never accurate. But when networking is completely shutdown when the GPS radio is turned on, it seems to work as expected. Using the 'GPS test' app, my accuracy goes from 100m/ no lock, to approx. 3M 3d-lock, just sitting inside on my desk, and it maintains it. I'd say my old Pixel phone still has slightly better gps accuracy overall, but this is very usable now. And, I don't reboot very often -- phone is always charged, etc, so the workaround is doable for me. If I do need to reboot, just have to remember to use airplane mode first. Otherwise, seems to work as expected now.
Hope that helps someone.

thanks for posting this. Wow. That is a lot of headache to run through. I will try that as well. As I absolutely can't stand the GPS on this phone.
I have also found a workaround, although it involves toggling the location settings on and off. IE toggling the Wi-Fi and Bluetooth scanning on and off. Generally this works for me, although sometimes I have to reboot the phone
