Hi,
I bought my Nexus 7 about a month ago. It works perfectly apart from the GPS. It can get a signal fast enough when I'm outside, but if I'm in my car it will get the signal will stationary, but once I start to move it loses connection and I have to come to a stop for a while to regain signal.
I downloaded the GPS Status app and looking at the number of satellites I have about 8/8, once I start moving it drops to 0/2 sometimes 0/0.
Should I take this back under warranty?
Thanks
Nick
I dont have this problem. Try latest update 4.2.2 and see if there is still problem. Also download FasterGPS (if you are rooted) and select your country. If not just replace it with new one.

I have already updated it. And it not rooted, guess I'll take it back.
Thanks for your help

Sort of depends - on a number of things
- # of satellites above the horizon
- clear Brillioun zone (no trees etc)
- sitting inside of heavy buildings or metallic enclosures (like autos)
Metallic cabs on vehicles have a way of making signals that are already at -155 dB in free space that much more wonky once you climb inside them. But if you have other consumer/commodity GPS units (e.g. a smartphone) that can maintain a good lock very well in the same vehicle, then perhaps it could be a hardware problem.
All these phones - Android / Apple / whatever - seem to come out of the chute with widely varying reception sensitivity floor (btw, there is no "connection", the GPS chip only listens). The original Samsung Galaxy was pitiful - it could barely maintain a lock with a clear sky and an unobstructed horizon - sitting side by side with other phones that worked perfectly. Never mind getting in a vehicle and moving - a lock condition was nearly impossible in that case.
The origins of the problem can be a poor gps reciever front-end, or more likely antenna design - possibly even interference from the tab itself (in the form of IF mixer spurs that land in the GPS band). Hmmm interesting - Asus is not exactly a cellphone design company - if your unit is a tilapia (3G) N7, does the problem change if you put it in Airplane Mode?
If it affects only a single unit, look for a loose connector for the external GPS antenna. There is a thread here on XDA in the N7 forums somewhere - search for that.
I took mine out for a drive with a different Android device right now - no speeds in excess of 30 mph, but they both seemed to hold lock with roughly the same error estimates. Unfortunately for the test, there were 10 satellites up, so maybe that test means nothing for when there are only 5 or 6 visible.
I doubt I'll be using my GPS much in a vehicle as it is WiFi-only (I suppose I could tether, but none of that seems like something I should be doing while I am driving It seems to lock pretty easily indoors, but that is not the problem you are experiencing.
(I vaguely recall that some of those Galaxy S users were trying to tweak GSP configuration files so that their devices would accept poorer lock conditions. I'm not sure if something equivalent is easy to do for the N7)
hope that helps - it's not a fix for you but at least a little more info.
I just tried it again outside alongside my nexus 4. My nexus 7 (which is 32gb without 3g) would only find at most 5 satellites and even then it would keep losing lock. My nexus 4 on the other hand would find about 17 satellites and have a lock on at least 9 of them. I then moved inside and my nexus 4 maintained a lock on most of the satellites whereas the nexus 7 lost all.
I think it is faulty in some way.
Thanks for your help
Hi all,
I'm on 4.4.2 (Singapore NC2) and I keep losing my GPS signal. No different from any of the other 4.4.2 ROMs I tried (all stock Samsung, initially not rooted but now I am)
I've tried:
- Turn off data (as someone suggested the Note 3 loses GPS when data changes from HSPA to 4G and back)
- rebooted
- Shut down the phone, take battery out and wait a few minutes before rebooting
- cleared the cache
- all sorts of location modes
, turned off wireless and bluetooth
- installed gps status and toolbox (another suggestion)
- full wipe and reinstall all apps
Things I have not tried
- wipe again (but I don't want to keep wiping to get GPS working)
- break the piece of sh1t in half
Is there any way to make this pile of [email protected] work. This is seriously THE worst GPS I had since the original Galaxy S (the S1).
I could not honestly say whether it was any better or worse before the upgrade as I got it two weeks ago and immediately upgraded to 4.4.2
Somehow, after I upgraded to NC2 it was fine but this afternoon it was absolute hell and took all the self control I had NOT to open the window and throw the POS out.
Any suggestions would be greatly(!) appreciated.
TIA

to be frank, wifi/data/blututh has nothing to do with the GPS. Mine is working well, has never disconnected when I needed (especially when I m driving)
have u tried to test ur gps ? u can use gps test to see how fast it is to lock a satelite, how many satelite detected, how strong is ur gps signal.
then you will know whether your gps got problem or not.
By any chance ur using aluminum casing? With it NFC won't work and very weak GPS signals.

Thanks, I know none of these should matter when it comes GPS except data and obviously the phone can scan for Wi-Fi networks to get an initial position.
When the phone gets a lock it usually does so within seconds and I've compared signal strength with an S4 and it's give or take the same.
Still, the Note lost the signal without moving, got it back only to lose it again and so on......absolute nightmare trying to navigate with it. I'll check it again today.
I have no case on it, it just sits in a Brodit holder.
It seems ok this morning.....I'll just keep an eye on it.
EDIT: Was OK for most of the morning while driving. However, this afternoon, after some playing some games, I took it for a drive again and GPS went all ballistic. I wonder whether it's a heat problem. I have another Note 3, also KitKat but different version, not rooted and when I put them both next to each other on a table they both intermittently lost GPS without being moved around....very strange.
Never had this issue... Mine only looses signal when i'm in a parking garage, on the tube or in between several high concrete buildings. But that's elementary physics, not a hardware defect.
Have you tried another GPS app?

Thanks, I've tried a few including GPS testing apps. Are you on 4.3 or 4.4.2?
I've also had the two Note 3, a SGS3 and Note 10.1 (2014 LTE so also Snapdragon 800) next to each other on a table outside. The SGS showed a rather consistent view of 6 to 7 satellites while the Notes (all three) had their satellite readings go up and down. However, ONLY the Note 3s lost the signal. It looks something like this: Has 8 to 10 sats in view, suddenly drops four, then another 3, then it's dead and then it seems to restart......and it's good again. This is all without the phones/tablet being moved or touched.
Mine does it as well rooted and before unrooted! Could be hardware although it's not as bad on Google maps more on waze!

4.4.2, NB7.
I'll test. Note that I'm inside a newly build concrete building between several servers and computers, and below 7 floors filled with people. (It's a hotel.)
Start: 22 in view.
10 sec: In use: 6. Accuracy: 60 meters
25 sec: In use: 9, Accuracy: 10 meters.
MapsWithMe and Google maps drop me in the wrong part of the building, but the readings remain consistent after it has sucessfully located me. Even when I'm walking down the hall it accuratelly follows me without skipping.
(It still thinks I'm doing it in the wrong part of the complex, but no connection is lost. Could be worse, most apps' locationservices still think I'm somewhere in the arse-end of nowhere in Eastern Europe. Dear Phone, I've seen enough of Serbia to say I wasn't impressed. I have no intention to stay. )
Mobile data on/off makes no difference, WiFi is off.
Is it relevant to mention that I'm in western Europe? Might be, for the number of sats.

Thanks for the test. I've been on NB7 (BTU). THis is when I first noticed the problem, the day after I got the Note 3.
All I can say is that it's fine again now. Something triggers the problem and once it's messed up it stays that way until I shut the phone down AND take the battery out for half a minute or so. A simple shut down and restart after a few seconds does not seem to help.
No clue whether this is related to there not being an Australian 4.4.2 ROM although I would have though Singapore would be close enough.....geographically.
I'm indoors at the moment and it has 13 satellites in use with 36ft (about 10m) accuracy and has been stable for the last 15 minutes. When it's screwed then I don't get a lock for longer than a minute or two. I'll just keep playing with it and if I can't fix it at all it's going to a better place
Thanks
I have the same problem. I'm on 3uk network and have to have a booster box for my phone at home as there is no network coverage on any network where I live but sometimes lose signal even with this. With friends, on same network, they have a perfect signal on their phones, none have the Galaxy Note 3 except me and I have have zilch. I didn't have any problems when I first got my phone but approx 9-10 mths later Gps signal totally unreliable. 3 told me the handset would have to be sent back to Samsung but this means I have to be without for, well who knows how long...
I have tried all the same remedies as you, none work. If you come up with any solution PLEASE post it here. thanks.
Hello,
Recently noticed my GPS barely works. If I'm out in an open field it can get medium strength locking from satellites in GPS Status. My wife has identical phone and gets the type of GPS signal I would expect to get. Side by side my phone simply cannot get much. Indoors forget about it. It use to be so good. I certainly have dropped this phone here and there but in the past it never influenced GPS. Is there any possible software/firmware side of things that could be causing it? I may have installed apps or updated apps but I didn't do any tinkering with the GPS specifically or with flashing roms or whatnot since this summer--and it worked fine then after any tinkering---this is a recent development.
Can anyone provide any ways to troubleshoot this? Possible the GPS chip is partially broken? I mean.. it can get signal.. just piss poor and struggles mightily. Almost can't get it in the car, loses GPS lock under tree cover, etc. Very temperamental.
Seems a little bit like 4G has also degraded but a little more unsure of that.
bump! Any help, methods to trouble-shoot between hardware/software. I tried to erase modemst1/2 see if that would jog anything, no effect.
thanks

It's freaking Christmas, just buy yourself a new phone
Sent from my HTC One using XDA Free mobile app
tempting..and I will in a few months when my contract is up. But this was a spectacular GPS for navigating in the backcountry with downloaded maps. Would love to be able to retain that use after it is no longer a primary phone.
please, any troubleshooting suggestions would be appreciated!
I've had very few problems since switching to Waze and SlimKat. It was horrid under CyanogenMod no matter what I used.
I had been having similar problems under stock KitKat. Here's what I noticed, maybe something will help you:
Resetting aGPS data and re-downloading wouldn't help.
Sometimes GPS would never give a location with plenty of satellites locked to. I modified some build.prop stuff to give me a horribly inaccurate lock in these cases. It was also usually fixed with a reboot.
GPS status would show TONS of satellites overhead, but never be able to lock on to more than one of them. Making sure I had wifi turned on (even if I was in the middle of nowhere with no wifi signals) eliminated this problem.
Something would randomly disable the GPS while I was using it, when it turned it back on a short time later it wouldn't lock (usually due to one of the above issues). I eventually concluded it was how Google Maps and some of the new location stuff works these days. I assume it's trying to save GPS power, other programs were much better. Solution: F Google maps; I only use it as a fancy yellow pages these days. I had stuck with the old, old, version (that still supported Latitude), but had to update when I went to KK and that's when my problems started. This is just another thing that pisses me off about it. I use Waze for navigation now (though I miss lane guidance and using my own text to voice software).
Some GPS bugs can be resolved by flashing to stock firmware, getting a GPS lock and while locked on GPS, reboot straight to recovery and flash your new ROM. After doing that once I have flashed (too) many ROMs with no GPS locking or accuracy issues.
Also make sure your GPS is set to high accuracy and not battery saver.

ezdi and kronik.. thank you for suggestion. unfortunately to no avail even with full reset.
sometimes really seems like my general phone reception, wifi, gps, and data (1x/3G, 4G) are all haywire. Certainly they all work. But the data is never as strong as it should be. Often seems like it needs to be jogged (airplane mode on, then off)/dead areas--while my wife's phone is solid (same razr m but rooted with unlocked BL and stock rom). Likewise on the GPS. it can certainly find and lock satellites but in GPS Status only ever reach 'half bar' strength green.. they use to be able to lock multiple sats at max level.
It's odd...we are talking about the 'radios' of my phone, no? or mostly? I generally consider digital electronics to either function, or not. That they function at all--can receive pings from a satellite, can transmit data to and from towers... tells me the electronics are functional and this is software side. UNLESS there is some radio hardware component that is an amplifier of sorts. If that electronic was broken it would make sense why things function but appear weak/spotty.
thoughts?
aside from my contract being up in a month and what the hell next phone I should get from verizon... haha. But no I'd love to get my phone back to where it was and have a dedicated backcountry/hiking/skiing GPS... which it wouldn't be capable of now (it was..when it worked).
Cheers

Hi All,
So I have an issue with my S5's GPS... I now suspect it is due to the antenna however would like some feedback and assistance.
I downloaded the "GPS Status" app to try and trobuleshoot a bit. When I open the app with my location on and set to any of the 3 accuracies (GPS only, Power Saving, High Accuracy) and very quickly it manages to find satellites, at the moment 26 of them.
However it is unable to connect / fix to any of them, so it is displaying 0/26.
So since it is finding the satellites but unable to fix/ connect to them I am hoping that my GPS chip is still fine but the antenna is the issue - what do you think?
If you think it is the antenna, how can I go about fixing it? Is there somewhere I can open up the phone and resit a ribbon or connector or anything of that sort? If so please can you assist me with how to go about doing this.
Thanks!
Psy
I use this one

atm, I have 25 in view, 10 in use, 3D fix, accuracy 33ft, while I'm sitting in the house
Which ROM are you running?
Alright, so I managed to get it working, I am running the stock Marshmallow ROM BTW.
What I did was remove the AGPS data and then boot into recovery and wipe the cache. Went out side and it started to connect and has been working fine since! Luckily ^^ Quite strange, not sure what happened there?
Nice one, yea it didn't sound like hardware, seeing the sats showed the antenna/GPS chip were fine
Probably just something corrupted, clearing caches is always a good first step to take troubleshooting
For all who have a hardware issue with the S5 that can't be solved by any software tricks, I posted my solution in a S5 Mini thread:
[Q] GPS Issue
Hello all, After 2 week I bought my G800H, the GPS star to take too long to get GPS Signal. Some times more than 10 minutes Even with 3G (H+) working well and the configuration in "High accuracy". Other thing that happens is the GPS...
forum.xda-developers.com
I posted this in another thread but it probably needs its own.
I just installed a Corehan 7" Android unit running 5.1 (lollipop)
https://www.amazon.com/Corehan-Android-Double-Bluetooth-Navigation/dp/B01G3LE5R8
The GPS worked great for about 5 days then progressively got worse. Now it doesn't work at all. I tried resetting AGPS but to no avail. Waze stopped working so I installed Google Maps. That worked right away then stopped working 30 minutes later. ( NO GPS signal)
With Waze if I uninstall Waze and reinstall it it works great for about ten minutes then starts to lose GPS signal.
I have 3 GPS test apps installed as well and they can all locate 3-6 satellites but none can get a location lock anymore. Could this be a symptom of a bad GPS antenna?
Is this a typical issue with these Chinese head units? I am tearing my hair out trying to figure out whats wrong. It seems like a software issue since it works immediately if I uninstall an app and reinstall it. (or that is just a crazy coincidence)
I also can run Waze on my phone right next to the head unit and it will work flawlessly.
Not sure how to troubleshoot or fix this. Any ideas?
First thing you can do, is check the location of the GPS antenna. Try putting it up on top of your dashboard (just for testing). Also check that the gps wire is connected to the head unit firmly. If that doesn't make it work adequately, return it.

this makes no sense if it was working correctly for days then progressively has gotten worse. Not to mention I already said it can locate 3-6 satellites (out of 12 or more shown on the radar) but doesn't get a location lock.

Has the weather gotten worse over a few days (yep, even WEATHER can impact satellite reception -- ever try watching satellite TV in a thunderstorm?)? Has the antenna MOVED during that time (which can happen if you hide it under your dashboard and it slips around)? There are a lot of reasons why reception can get worse over time. And you need more than just to "see" some satellites to lock onto a location. They have to be HEARD, CLEARLY.
So like I said, YOUR FIRST STEP has to be to reposition the antenna such that it has OPTIMAL reception.

weather is fine. Antenna is firmly mounted with velcro to where the factory antenna would have been. It is in the optimal position, as I said it has no problem reading multiple satellites, just can't get a location lock.
