I'm using Samsung Galaxy S4 mini (serranoltexx) running LineageOS 14.1 since 2018. Some time ago I'm experiencing such a strange problem with GPS fix. GPS chip can find satellites quickly with a strong signal (4 and more satellites) but can't get stable GPS fix. It may get GPS fix for a few seconds and then I need to wait again for the next GPS fix. It means that GPS fix is unstable. I can see the same behavior in any app for example gpstest.
Could you please give me advice how to troubleshoot this issue with the poor GPS fix?
In the logcat I can see the following entries after the GPS fix is losing:
Code:
04-17 21:32:48.092 598 1063 E LocSvc_ApiV02: W/virtual int LocApiV02::setGpsLock(unsigned int):3033]: Set engine lock failed. status: eLOC_CLIENT_SUCCESS, ind status:eQMI_LOC_ENGINE_BUSY_V02
04-17 21:34:08.358 598 1063 E LocSvc_ApiV02: W/virtual int LocApiV02::setGpsLock(unsigned int):3033]: Set engine lock failed. status: eLOC_CLIENT_FAILURE_INVALID_PARAMETER, ind status:eQMI_LOC_SUCCESS_V02
I'm tying to understand if this problem is related to the software defect i.e. LineageOS 14.1 or to the hardware - maybe GPS chip is almost dead. Also tried to Google these but no luck. I would not like to change the phone with no reason because it's very compact and handy. Thank you in advance.
Another question do we have here happy users who are still using S4 mini devices and not complaining on GPS performance with the lineage-14.1-20180624-nightly-serranoltexx-signed image?
I have the same problem Samsung Galaxy S4 mini (serranoltexx) with LineageOS 14.1. After repairing GPS it works briefly and then stops using GPS satellites even though it shows that it has found several 15 or more, but it does not get stable data from any.
I solved this problem on the software level. First I discovered that GPS fix is getting pretty fast when the phone in airplane mode. Then I replaced my SIM card. But this was useless in this case because the problem has been fixed finally after upgrading the Real Time GPS tracker application. I think that due to the software bug in this 3rd party application my GPS chip went crazy. Now seems all works good as before. I have tested it already for a few weeks.
That's good to know. So I'm going to look for which of my applications using GPS can do this a problem.
Thanks you
The problem is back from time to time. Sometimes rebooting of the device is needed to get the stable GPS fix.
GPS chip in this device supports GLONASS. But when I'm using GPS Test application I never saw that GLONASS satellites are really connected.
Can anyone confirm that GLONASS is working on these devices?
[ROM][I9190/I9192/I9195/L520/R890][Unofficial][11.0.0] LineageOS 18.1 for S4 Mini
Upgrade has solved all problems with GPS that I had. Even GLONASS is now working what was never worked in 14.1.

Hi all,
I am trying to find out how widespread the GPS locking problems are with this model. I am talking about non-assisted GPS, which can be tested using the "GPS Test" application on the market.
So, how is the GPS on your phone performing using GPS Test? Please give some detailed information like lock time, number of sattelites, urban/countryside location, and if possible firmware version of your phone.

My Spica cannot get a lock at all, will see up to 11 satellites but most of them with signal strength bars at zero. Firmware versions tested (all same result)
1.5 (XEJB2)
2.1 (XXJD1, XXJD4, XXJF2, XXJC3)
Same pb with my wife's spica. Samdroid version with FE7.
Can't lock withour assistance. What a pitty.
Go to your Settings -> Date & Time -> Uncheck Automatic and see if it helps
Or you can try this (need root)

i can get a fix under 2 minutes if I stay still...moving, it can take an eternity

i just don't bother with that any more...I might do it again after a month without wiping any data
rooting is like breathing to me ... as it would be to most of the people here
Anyone found a solution yet?
My spica wont connect via gps either. It just keeps blinking and nothing happens...not even after 30min.
I've tried GPStest and it reports that 12 satellites are in view but non in use, and there is no bars everything is at 0...not picking any signal at all :S
I tried my friend's one too and he gets a signal imediatley and a lock after about 10-30seconds.
Any solution to this? Is it a software problem or hardware problem?

I installed the alpha CyanogenMod 2.2 and GPS is working like a charm!
Problem was with the wrong libraries being used in many of the custom roms found at SamdroidMod. Devs found out about this issue and fixed it in this 2.2 release.
I'm running original firmwire which i got on the phone. (XXJE4)
I'm not willing to install alpha cyanogen of froyo yet...Is there really no other solution? I've had a chance to compare my spica to another one with original firmwire (JE4 too) ant that other spica worked while my gps had no lock. Also i had the chance to try one with samdroid on and it worked too.
Mine works from time to time. at the moment it works, earlier today it wouldn't get a lock no matter how long i waited.
First thing-delete /data/xtra.bin- this is data for agps which seems to cause gps locking problem. You can do it with RootExplorer/SUFBS or any file manager with root rights. Or use GPS Status and Reset agps data from setting. You can also try to swap libsec-ril.so, JF2 version works best for me. If you want I can provide update packages for libsec-ril.so
i have installed cyanogenmod 7.1 on mine, and can get a lock under 1min30s outside or under 3min in the bus near the window.
I have a rooted spica with android version: 2.2.2, baseband version: i570EXXJC1, kernel version:2.6.29 and Mod version:SamdroidMod-2.2.2-a9.
When I go to google maps app and click set location I always get an error saying: location temporary unavailable ! I checked the option on Settings->Location and security->Use wireless networks and use GPS satellites. And my phone is connected to the internet.
I just bought the phone last week, and its really embarrassing not getting this to work.

thanks for the useful info, you saved my life by this post.
i thought my gps is wrong in my spica then it was just a bug in the cooked rom. cyanogen mod is cool and gps is working now perfectly.
thanks again!
With spicagenmod + hp/yonip kernel gps work very well.
Hello!
I have LG Spirit 4G LTE H440N
Location is not working, when I turn off data or not being registered in any network after update to v6.0.1. With v5.0.1 things were kind of fine, laggy sometimes, but overall it was working and now with the same apps with preloaded maps it doesn't work at all. Here's what I've done:
- GPS test app locates good amount of satellites "In View" instantly, but it's always 0 "In Use" with no fix;
- This phone was already two times in warranty repairs (both only because of the problem described here), both times HW was changed. First time they changed some part, don't know what that was, but second time it was mainboard, I have a different IMEI now. Warranty is still ON.
- Tried to use GPS in offline with Samsung Galaxy phone, and it works there on Marshmallow.
Can anyone suggest a solution?
Hi,
I have another issue after the OS upgrade to Mashmallow 6.0.1, it loses the GPS signal every now and then for no reason, so I wasn't able to navigate using google map or waze or other location based Apps. I have to turn the Location setting off and on again a few times, sometimes it took a while, before I get back the GPS.
There is no lack of GPS signals in the area as my other devices are functioning properly. I have been using the phone for more than a year without such issues, started with kitkat then Lollipop, but as soon as I upgrade to Mashmallow the 2 major issues surfaced!
Any advice on how to fix this?
Same for me on my A3 2016 (6.0.1) On A310FXXU2BPG6
GPS signal is lost shortly after starting Google maps or Waze
:crying:
From few days ago my phone started to lose GPS signal, now with every GPS test apps I can see the satellites but it didn't connect to any. I tried different ROMs, came back to MIUI but nothing changed. Is there a way to restore connectivity as I think it's a software problem because I can see satellites, so the antennas work but don't connect?
Have a similar issue, started losing connection to GPS satellites, while using in the car.

Same thing here .
Tried everything
Going to replace the phone
Update:
After one day GPS started working again without doing anything. Maybe it could be related to Android auto as I'm not using it for 2 days and my problems started when I was using it
I am currently on Atom OS and have that issue of not working GPS every time I reoot. Have to disable location service (in quick settings) and reenable them for it to work, This is probably already solved in an updated version of my ROM, but hey, it's a quick try.
I have a similar problem, but I already have several months with my redmi note 7 and after moving to miui 11, the GPS works irregularly. I have seen many comments about problems with the GPS, but I have not seen any explanation from xiaomi

the GPS stopped working properly as if there was not enough signal,
how did you solve it? I see the satellites but a small signal and disappearing.
hardware repair - how?
or software? (goes downgrade miui?)
After update to Miui 11 i hve similar problem with my gps. I'm using app from Play stone - GPS FIX/OPTIMIZER and work fine. If i have problem with gps, run the app and restart.

thank you, the signal is better but still not good. In the woods I used to run when I had my cell phone in my pocket and the signal was OK, now the signal is lost

I'm looking for, but I can't find anywhere, even google didn't help me much
I do not have smart lock in setup / password and security
where it should be in RN7, miui 11
I'm on Cdroid and i find smart lock under security. I had MIUI before and i Remember i had Smart lock too. When you connect a new bluetooth device system should ask you about Smart lock. Try ti search in options
Hi guys
I was having the same problem with the gps connection. after changing my region settings from Brazil to Argentina, the gps returned to work correctly. test by changing the region and always restarting with each change.
My rom: V11.0.5.0.PFGMIXM (MIUI11)
I tried everything
also unlocked the bootloader and tried other rom
fix is not a problem, but the signal is still weak (large inaccuracy), with most satellites up to 20snr
a month ago there was no problem, I suspect the gps antenna, but I do not recall any phone crash, etc.
unfortunately I find nowhere manual, video, where the antenna and how to fix it

try to change the region, restart your smartphone and check for any improvement in the gps signal.
I tried everything, fix is no problem, I catch 12 sometimes more satellites (in open area), but all with low signal. Just go under the edge of the tree, and the signal is very weak and very inaccurate.
New Sony Xperia 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
Try GPS Connected app, it's available off Google Play Store.
BTW:
GPS has nothing to do with INTERNET/CELLULAR SERVICES. Your GPS receiver relies on radio waves. But instead of using towers on the ground as the cell phone does, it communicates with satellites that orbit the Earth. There are currently 27 GPS satellites in orbit - 24 are in active use and 3 act as a backup in case another satellite fails.
