GPS Issues on N based roms, please help - OnePlus 3 Questions & Answers

Since I installed the first N OOS build i have issues withmy GPS,
every few seconds it lost the lock and needed a few seconds to reacquire it.
Also sometimes it does not acquire ay lock at all and need a reboot to work again.
As far as I can tell the issue happens with every android N based OxygenOS.
And also with Lineage OS 14.1
I tryed clean flashing booth and it did not change anything.
Now I flashed back to the last MM based community build and it works no lost of GPS signal, reasomably quick fix.
Does any other users also have GPS issues with N based roms on the OP3?
How can I solve the issue or at least find out whaty causing the issues?

Funny you mention this. I use my op3 for my topo maps when I hike and I have found N based roms to cause the gps to require a relocking. Also, the gps is noticeably less accurate.
Anyone got an explanation/solution?

good to herar that I'm not the only one with GPS issues.
Now the question is how to fix those?

I am also facing GPS issues since Oxygen OS 4.x.x, before that I never experienced any.
Sometimes it take 5 to 10 minutes until it finally fetches a GPS Signal but it is still very inaccurate then.
Hopefully the new OOS 4.0.3 update helps, but I doubt it since there is no mention of GPS in the release notes.

I also have this issue, the only resolution I had is to switch on WiFi scanning. After turning it on GPS has been a bit better and locks to the correct location quickly.

Ok I found out something new when I set mobile data to 2G GPS works great also on the 4.0.3 OOS ROM.
And since people complained since the start that some have issues with GPS and 4G I guess the issue really is that if some particular frequencies are used GPS suffers. Apparently something changes in N ROMs that makes the issues appear for more users.
Interestingly is that flashing Modem Firmware has no affect so the issue is in a part that is in the android kernel itself.

Every time I turn location on, I get the "improve location accuracy?" prompt. Every single time.
How can I stop this? Never had this before, usually goes away after one enable.

Another strange thing sometimes the GPS cant get a lock and the only way to fix it is to restart the phone.

the bew Open Beta 12 based on Android 7.1.1 seams to have resolved my GPS issue really strange

Hi - I also do have heavy problems with losses of GPS- signal at the OP3 since months. Especially while using LTE the GPS gets often lost. Since 5 weeks I am working/struggeling with the OP-support a lot - but no changes till now. @David: "Open Beta 12" has solved your problems?? what is this concrete?

i do have the problem...... from 4.0.2 updated to 4.1.1 and now Beta13, the problem still there~!!

On my phone gps signal gets lost always at the same location and when lte is active. On any other location gps works perfect. When i disable lte everything works perfect. This has happend on any rom. I think this is a hardware problem and can not be resolved. The only solution is disabling lte or using a different provider. I am using o2 in Germany, the problem does not happen with other Providers. Different Providers have different frequencies, this might be the difference between o2 and the other providers.

I do have O2-LTE too and it is "under suspicion" in Germany. But in February I was for 4 weeks in Florida and travelled a lot using navigation. The provider was AT&T - and I had very often losses of GPS-signal too.
I can confirm, that the problem happens with different ROM, but not at only one location - it happens everywhere.
But what can we do? OnePlus is working at this problem since months without a solution - and the customer with this bug really have to accept it "for zero"??

Hello @OPFan , did you get help from the support? Or could you resolve the problem?

3 months of contact - lots of bubbles - no solution

try downloading the "Gps Test "app then enable GPS and open the app and click on the 3 dots > AGPS > Clear and update

this was one of the thousands of tryings - but also with zero effect

I'm having a lot of GPS issues since I've been using OPO or OP3.
I sold my OPO because of the bad GPS. Now I have the OP3.
On both phones I used custom ROM Cyanogenmod.
I sometimes had bad GPS reception, but this was fixed under Cyanogenmod doing this: Disable GPS, Disable Data, Enable Airplane mode, Disable Airplane mode, Enable Data, Enable GPS, then wait for GPS reception and start navi app.
Last week I flashed my OP3 with another ROM (AOSP) but this only made it worse!
I use my phone as car navigation daily, and while navigating, it finds GPS and it loses GPS every 5 seconds (using WAZE app). It's incredibly annoying. Using AGPS or any other "fix" found online doesn't fix the problem.
When using another navigation app, like Google nav, it's works better (because Google also uses LTE). Clearing cache or unistalling and reinstalling the WAZE app doesn't fix the problem.
Conclusion:
It is totally not related to your provider because they are working on fixed standard frequencies and I've been using the same provider on both phones.
It's also not related to the hardware only, because it was working on my OP3 under Cyanogenmod. So it should be related to the hardware driver included in the ROM.
Maybe this gives anyone an idea?

I have also GPS issues. It works well in gmaps, but it is unusable in Waze.
I thought AOSPA was causing it so I cleanflashed latest OB, but GPS issues are present there too

Tasker Locations Not Updating

Does anyone else have any issues with Tasker locations not working. I can't seem to get it to fire when using the cell phone polling when changing locations. I have also tried Llama as well and I have the same issue. I worked fine on my EVO and EVO3D but not the Samsung Epic 4G.
When I go and create a new state based on Cell Towers it will locate them but it will never update when I leave the area. I have also tried using network option but that doesn't work either.
I would like to know if anyone has these options working.
Thanks.
I have used location. but it was based on GPS. only issue I have had so far with this phone and tasker is the proximity sensor triggers but never turns off.
I've noticed that locations in general don't properly work with this phone unless you have GPS enabled. The phone is supposed to be able to get a location based off whatever cell tower it's connected to, however it doesn't update this information unless you do a reboot. For instance, my phone still thinks it's connected to the tower nearby where I live despite being 14 miles away in a different city where I work. Google Maps, Open Signal maps, ANY application will tell me the same thing. It's an annoying bug that's been around since the phone came out.
For me, GPS and network location services seem to die after being in deep sleep for a while. Opening Terminal Emulator and restarting the GPS Daemon by typing "gpsd" gets GPS going for me again, haven't got network location restarted yet.
I also don't know if this has been an ongoing issue or not, just started really noticing it on the recent EL leaks. I'm hoping Samsung gets it fixed soon.
That's pretty much the same problem I've been having. I have gone back and forth with the developer for Llama and he said that it's a OS issue that's the cause.

What i did to resolve this problem is i did a full stock restore back to eg30 everything. i backed up the Network location apk and the gps.conf file. I then rooted again and flashed the latest Calkulin's v.2.8 ROM and restored the stock files into the custom ROM. GPS lock is instant and updating to current location is a snap. this kind of surgery is not very scientific but it works every and all the time. Im working on a .xml that will take care of this instead of me cutting and pasting with from ROM to ROM.
Hello, I just purchased an Epic Touch and have had the same problem, where coarse network-based location does not work correctly. It also seems as if it's an OS-related issue since coarse location does not update in google maps, either.
The only temporary resolution I've found is to release and renew the aGPS state using a 3rd part app, such as GPS fix or GPS test. However, this is useless when trying to use tasker to switch between different location-based states...
Has anyone found any resolution since the OP?

Icecoldsandwich 8.2 tether and gps

I don't expect a fix but just found on the last few rom versions released that although the hotspot will work, if the mobile data connection is lost the phone will reboot . when on the train I noticed it happened in the same places on the route. I replicated the problem by manually turning data off.
The gps seems to work great, but only for about 1 - 5 minutes before loosing signal and not finding it again unless I turn it off and on again.
It's such a shame as I love the rom and way ics works over hc.
I had to post here due to under 10 posts so far...
Great work and kudos to all the developers producing ROMS

Just flash new 8.3, and if your phone randomly freezes use BFS kernel instead.

I haven't flashed 8.3 yet. For 8.2, there is a known workaround for GPS fix. Assuming you are using Naviagation, once you get a GPS fix, turn the GPS off manually while you are still in that app. Now, turn it on again. GPS fix should stay on just fine.

Same GPS problem loosing lock after approx 5 min with Ice Cold Sandwich 8.4 using Google navigator. Turning gps off/on does not fix but having a background process like Trapster keeps the gps lock active.
Try "Wireless Tether for Root Users" from google play store, wifi tethering should work with this app

[Q] Huawei P6 GPS doesn't get a Fix

Hi,
I have a GPS issue.
I purchased the P6 2 weeks ago.
It takes the GPS a long time (15 minutes) to get a fix on my location.
I have now upgraded to firmware b111 hoping it will help but it did not.
I have searched the internet to find more information and it seems that NEXUS users on JellyBean 4.2 had a similar issue that was eventually fixed by a firmware upgrade. Also I found other phones (such as Samsung SII) that once upgraded to 4.2.2 had the same issue (one of them even posted on h**p://forum.xda-developers.com/showthread.php?t=2203367)
I have also found several complaints from P6 users suffering from long delay times until GPS gets a fix.
I have installed App called GPSTest on this P6 as well as on a different Andriod phone that I own.
holding both phones I activated the GPS and started the GPSTest App.
The App showed that the P6 is 'seeing' less GPS satellites and that the signal strength from the satellites is received as weaker on the P6.
I have sent a email to Huawei to notify them of the issue,
I urge anyone suffering from the same issue to do the same a post the Fault information on:

If any one knows how to fix it please post it.

I've reported to Huawei on this issue on their facebook but no reply from them.
You may try get this App from Play Store GPS Status - Test & Fix.
It works for me. I can get my location within 10 seconds now.:good:
I had a problem with the GPS initially on my P6. I would find that turning the 'phone off (power down) and then back on again would cure this until the next time I wanted to use the GPS when I'd have to turn it off (power down) and on again.
I didn't seem to suffer from this problem after upgrading to firmware 107 (from 105) but by then, Co-Pilot Live had also had an update so it was possible that either one of the updates cured my problems.
me too , i have problem with GPS , when i install some GPS program Sygic or IGO or NAVIGON , for first time work and when i turn again ... no gps signal no nothing ... Only work GoogleMaps ... i dont know why.... someone with my problem ?
Try B118 leaked rom.
I have the same problem with GPS getting a fix. I downloaded GPS info from Play sore and i get a fix in a few seconds. Very good app
Guys am recommending do not install latest gmaps ..! They SUCKS ! Just uninstall and it will uninstall just update .. older version will be still there..

I've been having this issue since I bought my P6: GPS radio literally dies, when you try opening any app using GPS that little dot with a circle in the notification panel's left corner fails to blink. I tried factory reset, b111, b118, GPS fix, gpstest and some others. GPS was back after trying some of this methods, but erratically.
This morning it was dead again and none of above worked. After reading some threads about this issue I read one mentioning that turning it off for a while worked for him. I did, and it worked. I suspect it is an overheat issue.

It happens to me as well that I need to switch off the phone and on it back to get my GPS work again.
But it's still slow. Sometime need 3 to 5 minutes or forever.

there is NO problem with gps but with google maps !!! u have to uninstall latest maps and install old ones like few months old maps .. it works great on my p6 .. gps lockig takes one minute or less
It's Google Maps
It's true.
The GPS receiver is fine. It's the latest updates of GoogleMaps that's causing all that.
After removing the updates, I had no problems getting a quick fix (pardon the pun).

Not entirely true. I had severe issues trying to get GPS fix with Ingress, so much so that it was unplayable. If you read the other literature it is definitely not only Gmaps.
Hi, I'm in B122 and i've fixed mi slow GPS start problem, using a little free app named "GPS status & fix"...
It has worked OK for me, now mi GPS has fix in 10-30 sec...
Best regards.
I just one to report that my GPS is working well after I updated to B118 ROM.

I'm on B118. Decent GPS lock-on speed (within a few minutes, outside).
But after using TopNTP, now it's within 10 seconds. Even inside my apartment. I tried a few different profiles until I hit the one giving me this fastest lockon.

i got a problem with my p6! maybe someone can help. couldnt get a gps fix so i restarted my phone. normaly that helps. but after restarting my phone the gps symbol doesnt appear anymore. if i start an app like gps test normaly a gps symbol would appear at the top of my screen blinking. gps test tells me my gps is on but i dont get any satelites anymore and the symbol is still missing! any ideas????

From what I recall, the GPS symbol only shows when you are in the app that's using it. For example, when you are in Gmaps or Navigation you will see the GPS symbol blinking in notification bar. However, when you are at the homescreen, the GPS symbol disappears. Once you go back to the app, you should see the GPS blink again. BTW what firmware are you on?
At least you get some gps signal. I tried using TopNTP, GPS fix, GPS status, but nothing works on B125. D:

GPS Issues

Sounds like I am not the only one having GPS issues with my HAM. I have tried pretty much everything to improve things but with little or no success. Just to be clear I am talking about GPS locking and accuracy not AGPS (mobile tower) or WIFI based location which seem to work fine.
Hopefully this thread will get noticed by HUAWEI and they will fix the problem which in my case is :
Inconsistent GPS locking, sometimes it locks on pretty quick < 1min other times the GPS icon in the notification bar just keep flashing.
Inaccurate GPS location when it does lock with the position jumping around.
Location and heading changes when stationary which are probably related. Looks like internal compass maybe buggy or is not getting used.
I very dependent on GoogleMap and its Navigator which is where the above issues have been identified. I tried Waze which seems to dampen the location and direction jumping a bit but the initial lock was still a problem.
Same issues in B906 and B907 roms, haven't tried B221 (trying it next but it looks like others experienced the same with this rom)
Tried:
GPS Status and Toolbox - no difference
GPS Fix - no difference
http://forum.xda-developers.com/show....php?t=1563226 - Used Method 2 and with SSL as suggested by member svvv - Improved AGPS and WIFI based location lock but didn't help with the GPS
Never had this problem with any of my previous 4 Androids and even my old Windows Phone worked flawlessly. Maybe its something to do with my HAM being a Chinese model and it also having GLONASS which has better coverage in the northern hemisphere. Will see if I can set it to just use just the US GPS system in the build.prop.
Its a shame that Huawei stuffed the GPS on the HAM, it would be my perfect phone otherwise, if I can't get it going reliably it will be the Galaxy Mega for me as much as I hate Touch Wiz......

If ur AGPS is working fine eventually ur GPS should work fine. AGPS will use network to locate the GPS satellites.
try changing AGPS settings in the Ascend Mate secret menu *#*#2846579159#*#* under backgroundsetting
Thanks Svvv, will see what options come up. GPS usually eventually locks but it's never that accurate. Will A GPS improve this?

AGPS wont be that accurate as GPS...but whenever mobile cant fix a position with GPS satellites it goes for AGPS until GPS becomes active. U will not see any difference in the navigation.
Also try using GPS in the open skies mostly u wont get a fix inside a house or closed areas.
Thanks Svvv, that's what I found. Still can't believe Huawei couldn't get this right, even my wife's $50 ZTE's gps works like a dream. Searching through the P6 forums shows similar problems, not surprising given the similar hardware. I'm starting too suspect it's a hardware problem, maybe antenna related so I'm not confident of a software fix. Spent far top much time on this and I need accurate navigation so it's so long HAM. It's a shame, great phone otherwise, going too miss the battery life.....

GPS update. Tried B221 for a week but GPS issues were the same, positional accuracy was seemed slightly worse.
Rom was more stable than b907 though, no random reboots or system freezes bit b907 has better functionality. Very jealous of my wife's nexus 5, can't tell you how good the hardware and software is. A absolute bargain!
Can't go back to a small screen though, fingers crossed we see a nexus 6 to bridge the gap

since i dont quiet use gps in phones (i'm using other gps only gadget) i'm sure there must be something missing in the HAM that prevent it having good GPS signal/system.
well, if you ever wanted to replace the HAM, still wanted the same Batt Power, big 6.1", why not go for the HAM 2 which is LTE version with many improvements over the first HAM, heard that they improve GPS too.
It is the same problem with Huwaei MT 7 - I can not believe the this company did not discover this issue in their product yet, this is what is bad about the Chinese products
Strange, all of a sudden Yesterday, it seems all the people I know with Huawei phones have no GPS (Mate 2 and P8 Lite). I checked 6 phones. Worked fine Sunday, then BOOM Yesterday (Monday) no GPS no matter what I do. Any one else having this issue? I am on Android 5.1 B322.

Wow so im not the only one that's weird I just did the upgrade to b322 Saturday so I though something screwed up there. have you seen any devs come up with a cause or solution?
I had the same experience with my ascend mate 2. Mt2lo3. GPS is laggy to an extreme. Maybe the Chinese GPS Data connection. web.omwtoday.com???

On and off GPS issues

For awhile now I've had issues with the GPS on my i9192 where, using GPS Test, it will:
See multiple satellites but not get a lock
Seemingly "freeze" (satellite signal levels in GPS Test stop fluctuating)
Sometimes work fine
Sometimes only see 2 or 3 satellites despite being in a good location
These issues translate into GPS problems in my maps application (Here Maps), e.g. the maps app will be unable to get a lock, sometimes showing it has a lock for a second and then losing it again, which makes GPS navigation impossible.
I'm wondering if anyone else has experienced issues like this and whether they found any resolution, or whether anyone has any ideas as to what the cause might be.
I've tried:
Resetting/updating the AGPS settings in GPS Test
Editing gps.conf through FasterGPS
Editing gps.conf manually with various settings (rebooting after each change just in case)
Changing ROMs (from CM to LineageOS 14.1)
My feeling (and hope) is that it's a software issue since it seems to work better after a reboot (though not always). My next troubleshooting step will be to install a stock ROM and see if it resolves the issue, unless anyone else has a better idea. In particular I'm wondering if flashing a different modem/baseband would affect the GPS performance. Right now I'm on XXUCOA2.
Anyone have any thoughts?
An update: After reverting to a stock ROM, GPS performance was vastly improved, with no sign of the troubles getting a lock as was the case with LineageOS 14.1 and the CM ROM I used before that. I'm now trying to go back to Lineage OS 14.1 to see if the flash of the stock ROM (and new baseband) may have fixed it, but initial tests using GPS Test suggest that the ability of the GPS to get a lock is not as good as stock (too early to tell if I'll have the same problems not getting a lock at all).
It seems I have a similar problem right now. I'm using the lineage-14.1-20180624-nightly-serranoltexx-signed image for a long time. But last summer I noticed that GPS fix takes longer time to obtain and it's instable. Now I can't use navigation due to this problem.
