Cannot get GPS fix - ZTE Axon 7 Questions & Answers

GPS on my bootloader unlocked A2017G cannot get a fix for some reason. I last had working GPS on the November 12 release of CM13, lost it when I flashed the November 23 release (to get cam to work) and today finally decided to flash DrakenFXs B06 on top to see whether that might fix it (some indications of it in the CM13 thread).
However also on B06, much as with CM13, GPS Status just sits there telling me it sees somewhere from 18 to 27 satellites (so more than enough for a fix) but never actually gets a fix. Does my phone have a hardware issue or is there anything I can try (I may try to flash stock recovery if I can find it somewhere to go to B08 as I can get the OTA on my phone)?

Update: Flashing the full ZTE B06 update and then going to B08 did not help, either (and I now get a BL unlocked flash screen, I really hate those).
I still think it´s weird that GPS status says it can see that many satellites but never gets a fix out of it? Other radios work, so I don´t think there is something wrong with the antenna?
I guess unless someone has a good idea, I will send it back to Amazon.
If I can get a refund I think I will go for the OP3T instead (or bite the bullet and get a Pixel XL).

Maybe I am just expecting too much by testing indoors, outdoors it did work in seconds...

Yesterday I finally went from locked rooted B03 to unlocked rooted B08 and since then I notice that indoor GPS locks take much more time. Checking the GPS settings, I noticed that the Qualcomm IZat location service now only has an 'Agree' and 'Disagree' option when selecting the service. In B03 it was possible to switch it on and off with a checkbox. When either selecting Agree or Disagree, the box disappears and there is no indicator whatsoever showing whether IZat is actually turned on or off.
On B03 switching this on massively improved the GPS lock time indoors. Now, I do not really notice any difference whether I agree or not, indoor GPS lock in general takes a lot more time.
Anyone else?

gps not working?

got a new phone from tmo today...rooted it, flashed jf1.5, flashed new spl, moved apps and dalvik cache to sd...smooth sailing...redownloaded all my apps from sd and from market, still good...went to google maps and it cant find my location using gps...cellular location still good though...and yes, I did enable gps in the settings...so I reflashed did everything as before and still no go...did I just get a defective G1 or is there something I can fix? Thanks for any help guys!
BTW, my old phone, before it got wet, worked great with all the same settings and same ROM...
GPS can be iffy. Some locations are just prone to bad GPS acquisition. I went to visit my parents last night, real hard to get a fix in their backyard, but eventually it did. Tried at a friend's apartment building, anywhere NEAR it, its impossible to get a fix. Probably something to do with signal reflection. Other times, it'll lock on within a couple of seconds.
Your radio and firmware version are also important. The newer versions seem to lock on to GPS a lot easier. You say that you have jf1.5 -- the latest is 1.51, and can you confirm that you have the latest (official, not the hacked phone killer) radio installed?

I do have jf1.51...and the latest radio...and the latest SPL...my old phone didnt have this problem...I kept all my settings(thank you MYBACKUP PRO) so essentially everything is the same, except for the phone...and the same spots where I used to be able to get a fix with my gps(even indoors) I dont get anything....must be the phone...and if it is...any fixes you guys know about?
just got off the phone with a tmo rep re: my gps issue....I explained to him that I used to be able to get a gps lock on my old phone in seconds indoors and out but not with this replacement phone and he says to me well I have a g1 here with me and Im not able to get a gps lock...I told him that it's probably because he's inside a building with lots of electrical interference and other buildings blocking the reception...i also told him that I was able to use TeleNav with my old phone along with other apps that required gps...and he suggests to me to call TeleNav because it might be a problem with their app...oy...he also suggests to me to go to a tmo store where they have demo phones and we could compare gps signals....oy...I also told him that that I used google maps as a navigation tool before but not anymore since I cant get a gps lock anywhere...and he just tells me to try the tmo store...oy...i might need to unroot this phone and return it to tmo, I guess....

GPS doesn't work on Kitkat

So I installed a few different stock Kitkat roms on my note 3 (Australian version). At some stage I realised that the gps wasnt working by not getting a singal. I've gone and done many fresh installs with odin of different stock roms and still can't get it to work.
I've used gps status and after fixing a-gps data it will sometimes show many satellites on the horizon but with a very weak signals. If it does finally get a signal after a reboot it won't work again.
I've manually replaced the gps config file and it doesn't help. Also when I use an AOSP rom the gps works perfectly, locks fast and accuracy good.
Any ideas/suggestions on how to get the gps working again will be appreciated!
Not sure to be honest but I have two Notes here with different antennas (our whatever it is that sits on top of the GPS chip), running different Roms but they both seem to get into a state where they suddenly lose the signal, from 10 Satellites or so down to none, then reset GPS and eventually get it going again......could take quite some time or require reboots.
I find that X-Note (non stock kernel!) is much better but did not completely eliminate the issue.
I've rooted one of the phones so I can't return that for warranty and knowing Samsung Australia they would do nothing to help me anyway.
I'm pretty sure that ALL Notes have the issue but it seems to be random and only triggered after some time off operation.....so if you're not running GPS all the time you may not notice.

Someone has posted a gps fix zip. Which is supposed to work. I was afraid I might break something so didn't try it. I installed bob cat rom hoping that would fix it. but it didn't. Mine is international lte. So it isn't supposed to have the gps problem. Knox has tripped over so I am out of warranty. As the aosp rom works go back to that. Or just go from rom to rom till you have what you want which has gps working. I think x rom has working gps but not sure yet. Will know once installed. And i will find that gpsfix zip and install that.

That GPS fix zip is for 4.3 ONLY and will create a boot loop on 4.4.2.

Thanks, wouldn't happen to have a list of n9005 4.4.2 roms with gps fix installed would you? I think thousands of people would happily void their warranty to get it. That is the only reason I installed another rom and voided mine.
But it didn't fix the gps neither do the gps status etcetera.

Sorry but I don't. I think ALL 4.4.2 have that bug, at least all the ones I looked at. I don't know whether this is an Australian thing but it's very strange.
When it gets 'confused' the map that usually shows the satellites in view (or that should be in view) has ALL of them in one spot at the top end of the circle. A clear AGPS data usually fixes this but it sure looks like a software bug. I assume Samsung will eventually fix this. It ONLY happens certain times of the day. yesterday it did not happen before 14:30 but when it did, it did so on both Note 3 I have access to.

For me in australia with lte version it is a case of never getting enough satelites to get a fix and losing soon after. While my i9305 and my wife's n7100 both work fine all the time. So I cannot see it as just an at and t or verizon usa problem. My phone is with optus who updated the firmware as soon as I turned it on. But as I wrote no go so tried sweet, x, omega, bobcat stuck with bobcat 8 more success with gps on 8 than 9. Hopefully 10 will be more like 8. Perhaps 4.4.3 has a fix..
cheers
Curious, there seems to be a multitude of Australians with this issue..
You're going to have trouble aquiring a GPS lock these few days everywhere though. There has been a CME on 04/06/2014 (international dating) that hit Earth at 07/06/2014 and sparked a G2 geomagnetic storm. It plays havoc on all radiosignals, including GPS. It'll be bothersome for another week or two, most likely.
Gps experience with stock rom
Here is my experience in Without rooted complete stock ROM GPS Locking Time.:good:
Bought SM-N 9005 in December(U.A.E)- Jelly Bean- GPS Lock within 4 to 5 Seconds without any Help of Internet.
January Flashed Kitkat Poland (XEO) GPS Lock within 60 seconds without Internet, with Internet 30 to 40 Seconds,:crying:
April Flashed UK (BTU) GPS Lock timing same as Poland.:crying:
May Flashed U.A.E version again GPS LOCK WITHIN 4 to 5 Seconds without any Help of Internet.:good:
I am from U.A.E my question is GPS has anything to do with region? I mean GPS software is inside CSC or ROM or Kernel????
Try entering root folder and open up etc>gps.conf using text editor and change LPP_PROFILE to 3 instead of 0.
sama with me. i alteady try many rom include stock ne4 firmware. cannot lock the gps signal. felling sad.

Does this phone have problem with GPS/GLONASS?

When I got the device yesterday the GPS locked just fine. Then I saw there was an update and I thus downloaded it and flashed it via Odin as I find that easy than doing OTA, besides I was rooted!
The thing is, after the software update I rooted the phone again, by installing SuperSU from Play and updating the binary files and all that, then under SuperSU app it asked whether I want to disable KNOX or not, I obviously hit on Yes. And I think since then the problem has started. The GPS is not getting any lock. It can see 26-28 satellites but can't lock on to a single one! Before that I was getting more or less okay locks, around 8-10 sats out of 26.
I tried Faster Fix, didn't work, I unrooted by the SuperSU app option, nothing! Now finally I master wiped everything again, and flashed the ROM, and now GPS is working again! However I am not rooted as of this moment.
There is no doubt that this is a software problem, but the question is, how can I fix this? I have to depend heavily on GPS due to my line of work, I can't live without it.
Is it the ROM? I am using the latest 4.4.2 ROM of UAE. Should I move to some other ROM? I am sure I am not the first one who faced this problem, so I would really like some opinions on this.
Thanks in advance.
So you mean the cause of the problem is rooting?
Try re-rooting to see if it works.
Nah, root should not have anything to do GPS lock, at least not by any measurable margin.
But now I am seeing lots of YouTube videos, and I am confident that Note 3 has some GPS problems after all.

Something is wrong with GPS with this phone, should be software I believe, but what I don't understand why there isn't a fix for this!
PS: Anyway, what is the latest firmware version at this moment?

Tried it yesterday mate. Found it on YouTube. Didn't do anything good.
After testing for a long while all I can say that this phone is very sensitive to GPS locks! Right now I am having locks of 8-10 sats/21 sats, and that too with 20 feet accuracy, indoor. But the very next moment there's no GPS lock at all. But one thing is reassuring that outside, under open sky, whatever the circumstances are it will be locked just fine, more than fine actually, but the problem happens indoor.
This certainly was not the case with my previous Samsungs, be it the Note 2 or S4. The day GLONASS was introduced it was a dream come true for me, but this phone's performance is somewhat disappointing.
I needn't to say anything, all those video links I posted above are clearly mentioning the issue.

Q: GPS slightly off

I have a retus (US) model on .33 build. I've noticed that my GPS sometimes goes slightly off. Not much, maybe 20-25 yards but it's enough to have my navigation reroute if I'm in the car since it thinks I'm on a different street. Anyone else have this? Is this something that can be fixed when my phone eventually gets upgraded software? Thanks.
US model g5 plus here. I updated mine to .67 with TWRP with the zip provided on this forum. I never actually used my gps prior to updating but I used it after the update and never experience it being off.

Strange GPS Issue

New X Compact, and out of the box has had a GPS problem. It came loaded with Nougat, and I updated ota each version one-by-one to the latest Oreo 118, then unlocked bl, and flashed Sailfish, and the problem is the same on all.
What it is, is that the GPS signal will get a fix on-and-off after every few minutes, but won't hold steady. Using SatStat app on Android, I saw that the effect was the same with GPS and with network location.
Using a GPS info app, I see that when there is a fix, I get a read on latitude and longitude and altitude, but never anything for speed or direction. Seems like the fix is so brief that there is not a chance to measure it.
It seems obviously a hardware issue, being consistent over many software states, but the hardware is obviously working, so not sure... I would wonder if it was an issue with the carrier, but I used the same sim with the same account on my previous phone and it was fine.
Any ideas?
Thanks
