[Q] GPS works well, but dies randomly

Ok, I started a new thread for this, because it seems to be a unique problem.
(Sorry if there is a thread already, I couldn't find it)
I recently updated the SGS to the official 2.2.1 via KIES.
The GPS used to be a piece of excrement before, with the upgrade it got really good: sees 6-11 satellites, finds fix in 5-20 seconds.
BUT
from time to time it just plainly dies. The symptoms are the following: no satellites, no fix, in GPS Test it shows only one satellite after 30-40 seconds, but its location on the "radar" screen is glued to the North sign.
I think it clearly shows that it's not a simple case of not getting signal, but something at the system-level.
The weird thing is, that it only gets better with 2 or 3 restarts. Only one usually doesn't help
At first I thought that the RAM sweep I generally use in the Samsung Task Manager did something to the GPS driver, but I stopped using that, and the problem resurfaced after a couple of days.
I'm at a loss. Any ideas?

[Q] GPS usage crashes phone

Hi,
every time I use GPS Navigation, it crashes my phone. It does not do this during navigation, but afterwards, about 2-10 minutes after terminating the GPS application and the GPS sensor.
Usually the phone is quite warm then. I cannot shut down the phone with power + sound up. I can only pull the battery.
This happened on stock 10B, 10C and numerous CM nightlies.
It happened with Google Maps Navigation and Navigon.
Anyone else having the same issues? Would you think it could be the April Baseband or rather the hardware itself. I tend to say it should not be the ROM.
Thanks for any help!

Solution
Just in case anyone has the same issues: updating to the May Baseband solved my issues.

The GPS on my LG G4 is horrendous

So I've had my G4 for a couple months now, and I've noticed the GPS is literally almost worthless. My location is set to on and high accuracy. My usual routine is to look up the route before I leave my driveway like any normal person. The GPS locks on after a while, and when I start driving is the problem. It either won't update to my moving position (I live in Pittsburgh and T-Mobile's coverage is pretty good) and will frequently freeze. Or it will randomly start locking onto random locations around my area but not on my car. This is incredibly frustrating obviously because I absolutely need my GPS to work. Does this sound like a hardware problem and how do I prove it to T-Mobile to get a replacement device?

With a clear sky, my GPS is amazing. But with heavy cloud cover I cannot get a decent lock.
Seems the AGPS (tower based location) is worse on this than any device before. Even with Wi-Fi on.

Came here to post the same thing.
For some reason, over the last few weeks, my gps started going bonkers for no reason. It will work just fine for 20 min and then all of a sudden it will keep thinking that I am 70 feet west of where I really am. So if I'm driving south on the highway, it thinks I'm driving parallel to the highway but 70 feet to the right of the highway. So whenever there is another road nearby, Google Maps thinks I'm on that road and tries to reroute me to get back on the highway. If there is no other road nearby, Maps will correct my location to the highway. It is really frustrating because it becomes useless with intersecting roads and constant erroneous rerouting. The arrow keep jumping back and forth and the app is giving me false rerouting instructions non-stop. Not to mention the map keeps rotating around because it gets confused about which direction I'm headed. Super confusing.
Once I reboot the phone, everything goes back to normal and the gps is once again super accurate (until it happens again).
This issue happens every other day or so.
I did update to 10N as well as rooting and putting TWRP on it a months ago (around the same time these issues started). Not sure if the bug was introduced with 10N or if it's related to the root and TWRP (doubt it).
I started really hating this phone as I keep getting lost while driving.

Is this the same type of GPS issue on Samsung flagships? Those require opening up the phone and lifting up the GPS leaf pins.

Have you tried using Device Only mode? I noticed that once I did that accuracy went to 100% while driving.
I think it's a software issue that shows up when the phone is not using the GPS and instead relying on WiFi and Cell for location.

You know, you might be onto something about the assisted gps part (cell and wifi)
Shortly after I posted the message, I started using this app called GPS Status & Toolbox. It has a feature of clearing and updating the assistance data (A-GPS) which it can automatically do once a day. Since I started using it, I haven't had the issue.
It's possible that there is a software glitch regarding cell and wifi assist

Los Angeles got hit by El Nino pretty hard with thick clouds for about a week but didn't have any issues with my navigation. I use TomTom go, Google map, waze, and MS Here depends on my mood but all were accurate. I haven't done anything to my phone except turning off WiFi assistance for GPS, you think that has anything to do with it? I think it was called WiFi scanning under advanced WiFi setting.

I find the LG G4 gps to be one of the best among the phones I have used. I have had Note3, Note4 before... those had horrendous gps performance issue.

GPS problem

Huawei P9 EVA-L19, stock latest firmware, using as car GPS navigation, randomly loses location.
On roads near big trees this is becoming often, even worth. It's like the GPS is hardly receiving satellite signals.
Anyone encountered this problem?

I have the same issue on my EVA L09 and no solution till now :/

Same problem here, with the time he works better ^^

First I thought the Waze App wasn't optimised to this hardware; Later I observed the same symptom happened while walking down on a street and watching Google Maps.
Recently I've reset my phone to factory defaults and up to now ... sshh... Now I'm monitoring it. Fingers crossed :fingers-crossed:

I am facing the same issue with my P9 Plus. It doesn't work even after I have performed a hard reset. Will be sending to the service center and see what they say.

After installing B378 update i still have problems with GPS and battery. I've done factory reset 5 times in 9 months, looks like this Huawei is my first and last one.
Overall good phone but I don't want to carry charger with me all the time and can't use Google Maps

Hi. I think I solved the problem (at least for me it worked).
After the last update my P9 (Firmware: C432B378) GPS started to stop randomly, becoming an nuisance using any Navigation APP.
After searching Google and XDA I've found that other people also had the same issue with Nougat and after trying some of the solutions I finally got the GPS working again.
The steps are:
- Go to "Advance Settings".
- then go to "Location Services"
- Press the 3 dot (on the top right) and select "Scan settings".
- Disable/unselect the Wi-Fi scanning (and "Bluetooth scanning")
Voilá, the GPS it's back again.

I'm facing the same issue and already made the configurations that you report, without success. Already made a Factory Reset, and same behaviour: very erratic behavior of GPS during navigation (with Waze, or Google Maps, or HERE WeGo). Also requested the replacement of the device for a new one ... and same thing with this second P9 ...
It's running EMUI 5.0 (build number EVA-L09C432B378).
I had a NEXUS 5 and never faced something like this: very quick fixing of GPS (P9 takes much much much more time) coordinates and no erratic behavior at all.

Disabling wifi and BT just makes indoor positioning problematic. This phone has got a cheap and loose, slow chip for GPS. It may save energy. Sell the phone for someone slow moving, who isn't a car driver...

Glonass satellites ar unknown
Someone of you had noticed that P9 can fix many Glonass satellites but without recognizing as Glonass satellites?
I tried with app AndroiTS GPS Test used in the same moment/position on my P9 (EVA-L09) and on my Tablet Samsung Galaxy Tab S2...
Tab S2 views many satellites and fixes faster... P9 sees the same satellites but indicates them with a question mark...
A software problem?

Guys I've solved it after some research!
just press it on the 4 corners with your fingers.
I've made it with the app "GPS test" launched, and after pressing it, it automaticaly start working.
Enjoy!!!

Hi, I also have the same problem after updating to Nougat (Italian telecom brand TIM).
Can you explain better how did you fix the problem by pressing your fingers at the 4 corners ???

What does it mean press on the 4 corners?

problem due to battery optimisation . Had problem getting signal using Waze. Go to Settings, then Apps, Go into Settings under the Apps screen again; under Advanced, select Special Access ; go to Ignore battery Optimisation; Select All Apps; make Waze or your GPS app as Allowed App to ignore battery optimisation. It worked for me.

I pressed the four corners and it worked...thanks for the info

Got this phone a year
This problem still with me, i need to use waze regularly. It just keep lost signal. Any solution for this now?

The turning off of Wifi and Bluetooth location services works for me. To be fair, I have used my P9 for GPS nav in my aeroplane and it has always delivered quick and accurate results. I know this as I run it in parallel with my aviation GPS and the locations match if you track from A to B on both GPS's. It also seems to update very quickly, which surprised me but it does. My max speed is 140Kts, so not high speed from an aviation POV but very fast for driving!

Asked around from the retailer regarding this problem and they directed me to contact the official Huawei Support service, who in turn replaced the main board. Still not perfect all the time.

Check this:
1. calibrate your compas
2.In Advanced settings - don't close compass application
Second day works fine on my P9 Pro

4 corner means?

Question GPS Issues

Anyone else experiencing GPS issues on the S23?
Sometimes it will work fine for a day, sometimes for a couple of hours. Then it stops.
Occasionally rebooting resolves the issue, but generally it doesn't. Yesterday I restarted and/or turned off/on 5 times without resolving. Some hours later, it just starts working again.
Looking at nmea loggers and GPS Test app, when it stops it either shows no data at all, or sometimes shows signal from just one or two and never finds any more so can't get position lock (other than network based). My old S20 right next to it will show 18-20 satellites at the same time and never faults.
I submitted a fault to Samsung. They said the uploaded system log showed nothing coming from GPS (fault was currently being exhibited) and phone will need to go back. This isn't always the case however, as sometimes it works OK.
Is there anything I can try before I send it off?
Have others had similar issues?

Try restarting in emergency mode (SOS) and do your tests.
If I were you, I would factory reset or even install firmware with Odin just to make sure everything is OK.
Send to Samsung is the last attempt.

Thanks for the suggestions. I'll give them a go and see what happens.

Calibrate your GPS in google maps. Tap your location and it had you move your phone around to increase its accuracy.
