I recently updated my unrooted phone to OTA Kitkat and in hindsight wish I didn't. The GPS that worked flawlessly in 4.3 is no longer locking with the satellites( at max 3 or 4 fixes) and Navigation has become useless. I installed GPS Status and performed the usual steps(reset, get xtra data) to get a lock but several minutes would pass by before a single satellite was found. This was done outside under a clear sky. Has anyone run into this issue after the update? Any advice is appreciated.
Not sure why that might be happening.
Especially on a unrooted device.
I assume you don't have a custom reovery or anything like that either correct?
I would first try going into the recovery and wiping cache and rebooting.
Sometimes if old data is held there I remember that causing issues on my vibrant a while back.
If that don't work you might need to try a master reset of the phone and see if that fixes the problem.
If you are worried about loosing app data you can get Helium Backup from the market and backup apps and their data.
Just needs a computer to trigger it at first that is running windows, since you are not rooted.

Thanks for the suggestions. Here's what I did since I didn't want to reset the phone. I downloaded GPS Test and went outside in the Minnesota cold and waited for satellite fix. After 13 minutes, the phone found 7 satellites. I hopped into my car and started google navigation and drove for half an hour from work to home. Everything worked fine all the way home. An hour later I wanted to see if the GPS issue was truly gone and to my dismay after waiting for 10 minutes it didn't get a fix. This is really a bummer that the KitKat upgrade did something to the GPS functionality that it's taking so long to set the gps location compared to the 20 seconds under 4.3
I will give another try tomorrow and then will probably factory reset and start anew.

Something is amiss in 4.4.2 GPS. I had the same trouble, although with GE 4.4.2 ROM and not the official OTA.
What I did was to restore my original 4.3 ROM (dbombROM) followed by restore of GE, wiping cache and dalvik cache both times. I can't explain why that helped. But it restored my GPS function. While I was not able to get a lock for many many minutes, I get a lock now within few seconds (10-15 seconds may be).
Note that when I went back to 4.3 ROM, the GPS did not work in 4.3 either, while it was working fine just before upgrading to 4.4.2... So, lot of mystery there! But try restoring 4.3 ROM and restoring 4.4.2 again.

Oh...you said unrooted. Most likely you don't have nandroid backups of previous ROMs. Sorry man!
I'd try the faster fix app: https://www.google.com/search?clien......1c.1.37.mobile-gws-hp..1.8.789.USXOSBGtK7o

Glad to hear that I am not the only one. This is my 3rd replacement phone already. The first phone was completely replaced because the battery was overheated and drained within 3 hours. The second phone was replaced because of the GPS locked issue. The third one which is the one I am using right now is having the same issue. I noticed the issue after I did the OTA from 4.3.
I also noticed that if GPS cannot be locked, pull down the menu, either switch off turn back on the airplane mode or the GPS will immediately patch the problem. It's just an inconvenient when you need to reach at the phone clipped at the windshield from the driver seat when cruising 70 mph without a long hand or worst... need to do that in traffic packed road.
I almost got the same issue before. I just rooted the phone and flashed the custom rom. Now it works

Hi there,
Now I've come across a few threads that mention reboot issues. However mine seem to be almost unique.
The biggest thread I came across was more along the lines of overheating.
Everything on my phone functions normally. GPRS / 3G, WiFi, Bluetooth (I think, never use it!).
First issue: GPS takes FOREVER to lock. A good ten minutes, at least. Whether I sit and wait for it to lock or just start driving. Makes no difference.
GPS eventually locks. A good 20 minutes (give or take a few minutes) in, and bang. Reboot.
My first thought was the radio. I was running the very latest one (in the radio thread). I downgraded. I tried 4 older radio's. Each previous one improving the stability. However all except the latest only keep the GPS working for around 20 minutes after locking.
This morning I flashed the oldest radio (first post of the radio thread, oldest one there).
Results in my testing on the way home are quite different. After 20ish minutes I didn't get a boot loop. NDrive went crazy, and stopped navigating. I restarted the app and the GPS refused to lock.
I had installed CatLog some time ago. In my early experimenting, I ran the logging while driving. It seemed to have prevented a reboot but instead created circumstances like above where the GPS stopped working mid-navigating.
I'm running Pays DHD Rom. When navigating its running on battery alone. Temps don't go above 35 degrees Celcius. My phone is rooted, s-off'd as well.
Does anyone have any suggestions?
Short of un-rooting, finding a stock like 2.2 ROM and turning S-on and sending it back to the shop I bought it from, I don't know what to do
Thanks.
In my personal experience all GPS receivers loose sensitivity over time. Some go off faster other stay fine for a few years. If it takes that long for your GPS receiver to lock it is most likely caused by lost sensitivity and no ROM will fix this. The very last thing you can try is to download one of the GPS manager apps and perform a full wipe of the GPS data followed by GPS cold start. It should lock within 2 minutes. Otherwise install a stock ROM and apply for warranty repair.

Agreed. Definitely not the rom. I installed cm7 and damn its a great rom but the problem persists.
I downloaded one of those GPS apps. When soft resetting it rebooted my phone sad days.

So I've pretty much given up.
Tomorrow its going back to where I've gotten it from.
After downloading the stock RUU (first Eclair and then Froyo. Lets just say Eclair didn't like my phone at all) and getting it on the phone, I'm finished.
The moment I turn on GPS... instant reboot!
If you ever have troubles like this, don't waste your time, just take it back!

Yeah, I know that seems to be a pretty common issue with the Desire HD, but hear me out!
I had my DesireHD for about a month and I love it. Been trying various CustomRoms and so on. A week or so ago I noticed that my GPS is no longer working. I think I was using CM7 back then. I decided to flash a different rom to see if that fixes the issue. Well, unfortunately not. I then tried a few different Radio images, but that also did not fix the problem. I just can't get a fix. It did work fine with different ROMs previously though. I went back to the very first RUU update (which includes 1.32. or something and the radio) BUT I still can't get a GPS fix.
Is the device "broken" or is there still anything I could try? With all the wipes, restores, different ROMs, I should have "replaced" all software parts that could cause issues, right? I read that there is something like GPS cache that could be deleted, but not sure if that's done with full wipes etc, anyway?
Any suggestions? I'd hate to send the device in as it's likely going to take "forever" to get it repaired.
Thanks in advance,
BoB!
Hi Bob.
How long do you wait for it to get a fix? As far as I know, the first time whenever you flash new ROMs, it will often take much longer than usual. After the first time, it will normally take about less than a 2 minutes.
Got try using FasterFix to set your ntp?
Do you install GPS Status from the market to perhaps monitor the amount of satellite found by your device? You can also use to download A-GPS data.
I used to suffer a lot of problem waiting to get a fix (I hate waiting especially when it comes to GPS). But now it seems to be behaving. Lol. Could get a fix between 5-15 seconds. Now at most it will take is still less than a minute. Hopefully this will go on. Lol.
Hi, I had alot of problems with my GPS. Tried with different radios and ROMS. Found satelites but could not get a fix.
Unrooted and sent my phone to a repair shop. They found out that there was a problem with the GPS antenna and changed that. Will get my phone back over the weekend. Hopefully that fixed the problem.
This could also be your problem. Unroot your phone and send it to the guys that now what they are doing
The title pretty much says it. Anyone have any ideas?

Mine is fine. Are you only checking inside a building?

Knock on Wood, I think I got the gps problems nipped in the butt!
I had to reset the tablet from system settings after having both updates installed, when setting up tablet (initial boot) enable all location stuff except for the new android 4.3 wifi location while off option.. Also make sure to disable backup and restore options while doing the initial install.
Now so far GPS has been working steadily ever since first initial boot, no need to reset and power up again and after trying it for an hour all gps apps back and forth its still finding signal sometimes instant sometimes 20 seconds or so but no issues like before this time...
Working like it should now! I guess a hard reset after all updates was needed to reconfigure things!
This topic is covered in thread http://forum.xda-developers.com/showthread.php?t=2382355 as well with some more detail.
While hard resetting your device after the updates does improve the GPS situation, there is still a problem that keeps coming back to haunt us. Perhaps a moderator can join these threads together?
I've been running the only official lt28 JB firmware for over a month now on an LT28at with AT&T as the carrier. Overall pretty happy with it, haven't noticed any 'day 1' bugs accept for the video recording lag (which for whatever reason is phone playback only? on my pc, through vlc, all the video's look great.)
However, only July 22nd, Google released the updated maps app....and things have kind of gone south for literally anything gps related ever since...
The issue is tricky. After i installed the updated maps app, my phone froze on the map screen while searching for a gps signal. After about 5 seconds, the phone rebooted...but it wasn't a full reboot it seemed...it only took another 5 seconds or so before i was back at the lock screen. If i hadn't been physically looking at the phone, i never would've noticed it happened. Before this update; i had never encountered this problem.
After the kind of 'mini' reboot thing...no matter what, any gps related app (my tracks, gps status, Torque Pro, etc.) would do exactly the same thing. If i turned the gps off or never used a gps related app, the phone would function normal as ever...after manually rebooting the phone by either a full reset, or just turning the phone on and off...the gps would function normally again...I could get a lock, could use any of the apps, etc...
after a few hours, though...it would freeze up on gps stuff again, and get into the same boot loop issue with any time the gps sensor was used.
I've tried rolling back maps, but the problem remains...and i'm kind of stuck now...I'm positive this showed up with the newest maps update, as i had been using JB for a while before it and never had any gps problem of any kind...
what i've tried so far:
flashed an AT&T ICS firmware back...gps functioned properly for 2 days without a single problem. because this is an LT28at, pc companion cannot do a repair for this firmware. I get a 'we couldn't find any software for this device' or something of that nature. I've wiped everything through flashtool, and reflashed multiple times, without any form of back up data. I'm not rooted anymore, as i wasn't crazy about the rooting method for JB to begin with. figured i'd just wait for the time being.
tried 2 different .ftf files of the same JB firmware...both have the problem.
clearing cache of any gps related app i have doesn't seem to effect anything.
the only thing that seems consistent is that the problem only starts happening after the phone has been on for a few hours. If it try gps after a fresh boot, it works perfectly. If i try again a few hours later, most of the time it freezes and quickly resets, but keeps doing it non-stop until i shut the phone off.
is anyone having anything like this? Any help would be greatly appreciated...
EDIT: this can be marked as solved i guess...found info on other phones with 4.1.2 having similar problems...something to do with memory allocation and the adreno 220 gpu...rooting and running a memory tweaker/task killer (greenify or autokiller memory optimizer both worked) has been a good enough work around for the time being...hasn't happened once since i switched autokiller to 'aggressive' memory management...no gps problems, and not one redraw...phone is actually running better than new now haha...
Hi,
I'm in the UK and received my Google Pixel 3 XL October 2018 and the GPS was working fine, in January 2019 it started to be spotty, It would take a long to lock onto the satellites and now it doesn't lock on at all. I've installed GPS Test and while it can see up to 30 satellites it can't gain a lock even with AGPS downloaded. I contacted Google and have subsequently received 3 new devices but each had the same issue. Using an iPhone I get a lock straight away. I wondering whether there is a software issue or the Pixels GPS isn't particularly good at locking on
Thanks,
Matthew
Found 30 used 17, accuracy 5m, got a 3D fix in about 5 seconds.

Thanks, its very strange, phone has been on for over an hour, no fix, every now and then it gets a partial lock onto one with about 20 SNR but then looses it, it's bright day, no clouds at all, phone has been completely reset. Another phone gets an immediate lock so I can't see it being my location.
Thanks,
Matthew
Do you use a custom ROM?
Hi,
No, it’s the stock Rom with all the updates applied to it.
Thanks,
Matthew
Then I don't see how you could have had four units with problem on GPS.
Unless you're restoring apps with an app like Titanium Backup each time?
Did you try to factory reset?

Hi,
Yes, I've done several factory resets and did an install of GPS Status and Toolbox from the Play Store direct. I don't understand it myself, it could be my location but another phone of mine (iPhone) picks up the satellites immediately so I am not sure what is happening.
Thanks,
Matthew
Mine worked perfectly until I went to Q. Now it locks at first, then loses it almost right away. It never locks again for that particular route. Saturday I went over 20 miles away, and it showed me right by my house... I just sent a bug report to Google. I suppose it's possible that this is a coincidence and it just happened to fail around the time I went to Q. Hopefully I'll find out!
