GPS signal lost while navigate

I'm experiencing issues when I use the navigation. After a while the message "gps signal lost" comes up and my phone is not able to get a singnal again. Until, yes until I switch GPS off and back on. The fix comes within seconds and I can use the navigation for another...5 to 10min until I need to switch if off and on again...
Does anyone have the same issue and/or a fix for that?

Are you on Stock or Custom ROM?

Stock Rom, stock kernel. I only rooted it

Not too sure. I had an issue on CM10.1 with GPS.
Have you tried GPS Status and Toolbox from the market, you can reset your GPS.
Also Faster Fix, also from the market allows you to specify your region.
Let me know if any of this has helped.

The problem is not the fix. It just comes up with GPS signal lost. As soon as I just switch gps off and back on, the fix comes almost immediately and I can use it for another 5 or 10min. I'm not sure if this might be a temperature issue. I mean the phone feels warm but not hot.

I have the same exact problem on mine! I'm stock everything, not even rooted. Both times I've used my gps to get anywhere this happened. The first time I was dropping someone off at the airport and was driving for about 3 hours total and the second time was yesterday when I had a 4.5 hour drive.
The first time I thought maybe it was cloudy or there was some kind of interference, although when I would exit navigation and go back in it was fine for another 10 minutes. After yesterday, I'm beginning to think it is completely unreliable. I won't be able to use it to drive anywhere because it is so dangerous to have to fiddle around with your phone every ten minutes to get the navigation to work again.
I am glad I found this in a search so I know there is at least one other person out there with the same problem. Do you think we just got bad phones and need to get them replaced?

I think I've solved the problem for my phone at least (or it's just a coincidence). Today before I drove home 4.5 hours, I installed cm10.1 on my phone and the whole time I was driving it only lost signal once. Although when it lost signal I gave it 30 minutes to find itself and it was following me but couldn't lock on and was only accurate to like 50 meters or something. As soon as I reset the navigation though it was pin point accurate for the rest of the trip.
I installed cm10.1 after reading in another thread about someone whose nexus 4 took an outrageous amount of time to acquire a gps lock. He said it was fixed by wiping his data.
So of you're still having trouble with your phone you could try backing up your apps and doing a factory reset or flashing cm10.1.

I haven't installed CM10.1 yet but thanks for the suggestion.
I installed francos kernel r15 and had on single signal lost yesterday.
I think it's heat related. I repositioned the phone after the first time it lost it and it was fine for the rest of the journey (45min)
I think the OS disables the GPS when it gets too hot. But instead of switching it off, it just doesn't work until you reset it. Werid.
I'm gonna try CM soon to see if it makes a difference to me too.

I have the exact same problem with my Nexus 4. Galaxy Nexus worked with no problem. Nexus 4, gps lock is achieved very quickly but then lost after 10 to 15 minutes of driving. After trying factory reset and manually reinsitalling the OS, I called Nexus support and exchanged phones. I never thought it was a hardware problem, but thats the only thing Nexus support could do for me. With the new phone, I reproduced the problem with both OS versions 4.2 and 4.2.1.
Now, the exciting stuff. For a little while I decided to revert back to my Galaxy Nexus (by taking my SIM out of the Nexus 4 and putting into the Galaxy Nexus). After doing so, I also did a manual reinstall of 4.2.1 (this was all before getting my replacement phone). To test the Nexus 4 with the reinstall, I used my Galaxy Nexus's wifi hotspot and connected my Nexus 4 to it and used the Nexus 4's navigation WITHOUT ANY PROBLEM! As soon as I put the sim back into it, the problem started up again.
My hunch is that Google location services (that use cell towers to triangulate) are somehow interfering with location services in general in software, and by putting the sim card back into the phone, I enabled Google location services to interfere with the GPS software.
No resolution to the problem, but just some interesting correlations!

I am having the same issue. Nexus 4 acquires GPS signal immediately. Using GPS Status app I clocked it at under 4 seconds. However, within 3-10 minutes of navigating, GPS loses signal and NEVER re-acquires it. I tried this with Google Maps, Mapquest and Copilot Live. Restarting the navigation application re-locks the GPS almost instantly.
Ultimately, the navigation function is not usable if you have to fiddle with the phone every couple minutes while driving. Google support was of no help. I returned the phone, but now regretting it, since it was perfect in almost every other way.
There are reports floating around that 4.2.2 software fixes the GPS issue. Can anybody confirm this?
P.S.
I am on T-mobile in Washington, DC area.

I'm having trouble with it too, 4.2.2. definitely does not fix the GPS issue that I have too!

Did you ever got a solution for this?

I think it was a heat issue.

Hey edgeball,
I was wondering if using the franco kernel is still working for you, and if you have tried upgrading to 4.3.
I just bought a nexus 4 and i am very disappointed to have these problems with the gps as i use the gps all the time.
I have the same problem where the gps signal is lost but the other problem that i am having (after a few minutes of navigating is the signal becomes weak I get this halo around the arrowhead that indicates my location. This halo i believe is showing uncertainty of location, meaning I could be anywhere inside the circle. Then the circle gets bigger, like 50 feet diameter. Then my location starts jumping around. I will be on one side of the intersection, then the other, then back again. And every time this happens the route is recalculated.
Then ultimately I loose the gps signal and it keeps searching until i either reboot of turn the gps off and then on.
This morning I installed franco kernel and I didn't loose the gps signal during my 45 minute commute but I did have this second problem I described there the location becomes inaccurate I my arrowhead starts jumping around the intersection.
I was just wondering if you have experienced the same problem.
thanks.
oh btw I am trying the franco kernel on slimbean 7 (4.2.2)

Given this, would it be possible to fix this issue by only turning on "GPS satellites" and not "Wi-Fi & mobile network location"? By doing so, the phone isn't looking for cell towers and WiFi. I have no idea on this topic but if a SIM card isn't inserted into the phone, would that not mean that the phone is not using cell towers for location?

[Q] How many of you are experiencing SOD issues on the Nexus 4?

Hello everyone,
I would like to know how many of you are experiencing the different kinds of SOD on the Nexus 4.
I found few references to the SOD issue, but no one could tell exactly why this is happening.
Some say it's a software issue (some say it only started to occur at JB)...
Some say it's an hardware issue.. some of them RMAed, and got a new phone with exactly the same SOD issue.
I would like to dedicate this thread to this problem and see how many other Nexus 4 users are experiencing this SOD.

Never had one so far. Running stock 4.2.2/Franco kernel nightly_110
-Edit- currently undervolted -75 mV.

just stop messing your phone up with stupid OCing and benchmarks... This issues are installed to protect the hardware from crashing... ( Red light of death... )

My phone just fine. never had this SOD.

Never had an issue on this device. On my old phone, dropping the min CPU speed too low would cause it a LOT.

You don't have an option for unable to turn on phone without a reset: no blinking led. This is also a scenerio.

Please take a look here! http://forum.xda-developers.com/showthread.php?t=2195278
I've tried almost everything (wipe& re wipe , install stock ) and nothing seem to solve it.... most frustatin thing is when I hit "home" after playing heavly and ...bamm it goes black screen & hav to reboot pressin home&vol+

Are you using a custom kernel to undervolt? That can cause SOD.

Im using it now (customROM&UV) since it doesnt affect my issue.... I tried completly stock for 2 days and keep crashin... or at least on g.earth as I didnt install any app/game to be sure its not an app related issue.
Cant figure out what happens, it can play games w/o any issue, but sometimes when I change orientation it just goes black
PD: I dont hav enough time, but ill do a logcat to see what can possibily make it freeze

My case is not listed in the poll options:
- the phone went into standy, good battery, no calls, no high loads;
- LED was inactive totally.
- then I was unable to turn it on normally (only through reboot).
While in this state, trying to call the phone resulted in "long" tones, i.e., like the network saw the phone. The phone did not ring.
This happens with the latest stock firmware on the 2nd day of my use. Non-reproducible. Phone returned.
Would be delighted to learn if that's a hardware or software issue

Not necessarily SOD but experienced extreme battery drain under these situations
1- Charging via USB and left phone connected after PC shut down.
2- Charging via Wireless Charger left it on the pod.
In 1st ASA pc is shut down
and
In 2nd ASA Phone charged completely , as I suspect the charging process goes backwards ! It someone drain current from your battery to the power source.
AFAIK none of these issue are positive with normal good old AC charging. However you can still use a workaround by using the app called "Safe Charge"
This is my experience

[Q] Erratic Blue Tooth behavior

I have a Nexus 4 that is about 2 weeks old. I love the phone, all except for the Bluetooth behavior. I couple my bluetooth heart rate monitor to the N4, and in order to do this in the morning, I have to restart the phone almost 100% of the time. I can't even turn the BT on with the slide switch, as soon as I push it to on, it goes right back to the off position. As soon as I restart the phone, all is well. Now I have read numerous complaints on other forums and on the Google help page with similar Bluetooth connection problems. Google recommended in several places that a total reset of the phone would fix these problems, which I thought was ridiculous, since my phone did this from day one. Anyway, some people have reset their phone as many as 3 times, and the problem is still there, so obviously, that was not a fix. Other Nexus 4 users have apparently got an RMA, a new phone, and have the same issue.
So it sounds like this is a software issue, and hopefully the new version of Jellybean will fix this problem, but somehow, I think that this issue is not being addressed, Any thoughts on this? h t t p ://productforums.google.com/forum/#!topic/mobile/nVjWKiUvvPs

This is a known bug, there's is no fix as of right now. I've had this issue on all 3 of my Nexus 4's.

It is software, remember 4.2 brought a new Bluetooth stack. I would assume that there are more than a few bugs left to work out.

Hopefully the next update will remedy this. They are recertifying the Bluetooth right?

4.3 Wifi issues?

Anyone else having wifi issues with 4.3? I am 100% stock unrooted, installed the official google factory image with fastboot doing a full wipe including user data. I have been running AOKP and have gotten sick of the issues this tablet has and though that going 100% stock to see if it solved any of the problems. I have only been installed since last nigh but I am already having wifi issues. The wifi seems to loose connection and has to be toggled on and off to get it going again. Anyone else seeing this?

I can confirm this.

I actually think my Wi-Fi is even better now.

I had the issue you described on 4.2.2 but not so far with 4.3, only time will tell. I'm getting random YouTube app freezing but these do not appear to be WiFi related. I flashed the 4.3 update over my existing 4.2.2. Stock image so have a different base then yours.

No problem with WiFi, it also seems more stable now.

As others have said, I've found my wifi reception/stability has improved with the 4.3 image. My older 802.11b hotspot didn't work with the N10 reliably before the upgrade to 4.3, regularly dropping the connection. Now it works fine, and always at full "bars" reception.
My 5Ghz 802.11n AP worked fine before, and still works fine now.

Hi, I too have had poor wifi on my wife's nexus 10 since 4.3.
Every night for last couple months my wife and I have played ticket to ride in in bed. From the moment she reset it to apply the 4.3 update (between games) she has suffered from dropouts and the game continually disconnects. Was running perfectly for months until this update was applied.
Given that she updated between games and we noticed the issue immediately after the update I am sure there is a change for the worse in the wifi configuration under android 4.3.

I am also experiencing wifi issues with the stock 4.3 update. No SoD so far like with 4.2.2 but since 4.3, wifi quality will degrade when I am using it heavily. I will still have 2-3 bars but the connection will slow to a crawl until I toggle wifi off/on. (I feel I should add: quality router, multiple devices without issues) The only thing I have done to this ROM is chainfire root. It seems some have the issue and some don't. I'll prob try and install again tonight to see if it helps.

I have been experiencing a loss in internet connectivity after 1-2 hours of inactivity now that I am on 4.3. The WiFi icon turns gray but stays connected to the router. I rebooted the router, but no help. I have advanced settings set to WiFi always on. I had WiFi optimization on, and am now testing to see if things change with it off. I never had any connectivity problem with 4.2.2 and nothing else has changed. If this keeps up, I may flash back to 4.2.2 till things get better.

That is a very simple fix if you just asked around, or searched and you would see the three primary causes.

I ended up using an app called safe charge that seemed to do the trick. What were the other causes or fixes for this? I just wanted to go stock for a bit while AOKP and CM get the 4.3 builds up and running so i would have a reference to compare the performance and stability to.

I have filed a bug report for this here https://code.google.com/p/android/issues/detail?id=58206&thanks=58206&ts=1375129699

The leading causes of sleep of death issues are:
The CPU governor uses hotplugging, the majority of the users on this tablet get SoD with hotplugging on
Voltage was tweaked a bit lower and is not enough to run your CPU properly
You are running Franco's R12 kernel which has a very widely known SoD issue.
It is also possible that the version of the AOKP kernel you may have been running had the same tweak that Franco did and was also causing a SoD. 90% of the time when someone has a sleep of death issue on this tablet it is because of something from the kernel that is causing the issue, you can try out KTManta or Trinity kernel (also both of them have beta kernels available for 4.3).

FWIW, after turning the WiFi optimization off, the WiFi status icon has remained blue and I have not lost the internet connection when sitting idle for hours.

Weird wifi behavior

Hello everybody since a few weeks I've been having a weird wifi problem. Sometimes, at random times the wifi disconnects from the network it has been connected on for a while and if I go into wifi settings I see that there are no wifi networks available at all. The only way to fix it is to turn it off and on again. This is really annoying expecially for missed emails and notifications. I really don't understand what the problem is. I've tried 2 different roms, pac before and slimakat now, always doing clean installs. I've also tried different kernels and I'm now on hellscore. I also tried different radios including hybrids (I use one now for lte). Nothing seems to make a difference... Could it be some kernel undervolting setting? I also have suspended back off wakelock, but I guess that's another issue. Also I tried wifi optimization on and off... Any help is appreciated. Thanks

If flash the factory image and see if the problem still persists. If it does you probably have a hardware problem

Ok thank you. Could undervolting be influencing it? It mostly happens when the phone is in deep sleep or when I get outside a building and I'm connected with wifi and then I got out for a few minutes and back in again...
