    My Nexus 7 is 16GB Wifi (second gen) version.
    It is updated to the latest version of the stock firmware (OTA. No rooting).

    i.e.
    Android 4.3.
    Build JSS15R.
    The GPS is still unreliable.

    The Navfree and OsmAnd apps will run from several to 10+ minutes and will stop because GPS is off.
    I live in Ottawa, Canada.

    No change, no improvement through all the n7 updates. Sometimes the GPS works and sometimes it doesn't.

    For those still having GPS issues - have you tried a factory reset since installing the latest update? I too had GPS issues after the latest update, but have had zero issues since doing a factory reset. It's a bummer to have to do it, but worth it IMO to have the issue fixed.

    I bought a new Nexus 7 32gb wifi-only tablet on Saturday. I had read about multi-touch and gps issues on the internet, but it looked like they were fixed in JSS15Q. The store let me test it, and it worked fine. It had JSS15R factory-installed out of the box. I went for a two hour walk the next day, and the gps kept a lock the entire time. On Tuesday, I tested it again, and the gps would not lock, even after 20 minutes. I tried removing apps, and I rebooted a few times, but it did not help. I also tried using a gps test app to refresh the agps data. I have an old Nexus 7 that I put next to it, and the old one locked with 10 satellites within a few seconds. I have not rooted either tablet, and I have installed only a few apps, all from the google play store. Some people have posted that a factory reset will fix the gps, at least for a while, but that isn't a solution when you are driving. I am going to return it.
    When the new Nexus 7 was working, it showed visible satellites with numbers into the 80's, so it can see more than US GPS satellites, but when it got a lock, it used only the lower numbered, US GPS satellites in the fix. Side by side with the old Nexus 7, the new Nexus 7 (when it was still working) took longer to lock (15 seconds to 3 minutes for the new Nexus 7 vs. 2 or 3 seconds for the old Nexus 7) and often had 1 or 2 fewer satellites in the fix. So in addition to the broken gps software, the gps hardware might be inferior as well.

    Did you have any OS updates after you left the store? If so, did you try a factory reset after the OS updates?

    Settings -> About tablet -> System updates -> Check now
    says "Your system is up to date". "About tablet" shows Build number JSS15R, which I think is the latest build.
    I was wrong before -- it did the JSS15R update when I initialized it in the store.
    I am pretty much decided to return it because I depend on the gps when I travel, and I don't want to risk another problem.
    In any case, I am doing a factory reset now.

    I saw no change after the factory reset. I have not rooted the device, and all of the apps are from the google play store.

    I had a case with a magnetic wake/sleep. Watching the graphs on "GPS Test", the case seems to reduce the GPS signals by around 5dB. Even without the case, I can find locations where the new Nexus 7 will lose GPS lock and show 0 signal strength on all satellites, while an old Nexus 7 next to it can get a GPS lock within a few seconds.

    In the photo, an old Nexus 7 is on the left and a new Nexus 7 is on the right. The old Nexus 7 has a lock with 5 satellites while the new Nexus 7 has no signal after searching for 8 minutes.

    I called google support one last time. The woman said 1) that google does not answer questions about third party apps, so they do not care what the GPS Test app says, they only care about google maps and 2) that on a wifi-only tablet, the gps will not work out of wifi range. She repeatedly insisted that the gps would not work out of wifi range. She didn't know the difference between the gps receiver and the google maps app. I suggested that she did not understand the problem and asked to talk to a supervisor, and she said that she could not do that, and that the supervisor did not know anything more than she did. I told her that I would return the device if I couldn't talk to a supervisor, and she still refused to pass me to a supervisor.
    After the call, I returned the new Nexus 7 to Best Buy. They gave me a full refund without any problems.

    When my gps isn't working it doesn't even matter if its in wifi range or not. I can't get a location fix even if it is in wifi range range. But when it is working I can get a location fix in or out of wifi range.

    I assume that you were within Bestbuy's 15 day return period.

    PS I HATE typing on this thing!

    Correct, wifi has nothing to do with it. The reps at google support are probably reading from a script, and if someone says "gps" and "wifi-only", the script tells them to say that google maps works only in wifi-range. A rep that I had spoken to a few days earlier had at least been willing to advance to the next step in the script, which was rebooting in safe mode. Safe mode was actually a good suggestion because it had no effect on the problem, which meant that I didn't have the problem where multiple apps accessing the gps simultaneously could lock it up. I never saw that problem or the touch screen problem, so I think that JSS15R solved the more blatant issues, and now some of the smaller issues are becoming visible.

    Correct, also, that I was within the Best Buy 15 day return period. They didn't ask any questions, and they even checked that I had done a factory reset. They also let me return a $40 case (which was expensive for being plastic and for closing with a clip instead of a wake/sleep magnet). The only other local store that had it in stock was the Office Depot where I bought my old Nexus 7 last year. I had originally gone to the Office Depot first for the new Nexus 7 because they said over the phone that I could return it for a refund if it didn't work, but when I asked again right before they took my credit card, they said electronics were replacement only and no refunds, so I left, and I happened to pass by the Best Buy on the way home.

    I was sorry to return it because it was a nice device, compared to the old model, it boots in less than half the time, the screen is about twice as bright (readable outdoors in sunlight), the screen is sharper, it has a rear facing camera (apps like goggles and price check are usable), it is thinner and lighter, etc. I might not have noticed the gps issues if I didn't have an old tablet to compare against.

    I imagine that google will eventually fix the gps issues, but I travel a lot, and I didn't want to be stuck with an expensive paperweight for an undetermined amount of time, and my old 2012 Nexus 7 still works fine. I also suspect that the new 2013 Nexus 7 has a design mistake that the gps antenna is too close to the wake/sleep sensor so the metal clips in cases with wake/sleep magnets block some of the gps signal. None of the cases sold by Asus have wake/sleep functionality, and since Asus knows better than anyone else where all the internals are located, that is a good indication that cases with wake/sleep cause some sort of problem. I have the Sygic navigation app and their off-line maps on my old tablet. When I travel and I am walking around or on a bus, I keep Sygic running but asleep by closing the case. It is fast to open the case, check where I am, and then close the case. With the new Nexus 7, I would have to use a case without wake/sleep which means that I would have to hunt for the power button (which is tricky to find when the tablet is in a case) or remember to push the navigation app into the background, which is a bit inconvenient.

    Hopefully the 2014 model will be better.

    I find this a very interesting observation. My GPS on my 2013 Nexus 7 is also toast, and I swear it was working when I first got the tablet about a month ago. I'm running the latest 4.3 with all updates. I also have a magnetic case and I noticed it really screwed with the compass but I didn't think that it would affect the GPS -- but I guess it does make sense. In any case, I bought mine online and I am NOT looking forward to going through Asus to get this replaced under warranty. I have tried everything -- factory resets, removing the case, going outside... The only way I can get a blip on google maps is with aGPS enabled, and I can tell it's not locking on any satellites because I'm only getting an approximate location. If I disable aGPS, google maps can't find me.

    No, that is not something you want to look forward to! I've been there and done that with my Asus laptop. What a hassle. There's a long thread all about the ordeal on laptopreview.com. The only worse warranty experience I ever had was dealing with Sony years ago with a VCR.

    As for my N7 GPS, it has actually gotten WORSE - and, no, I have no case. I used to be able to get a location fix sometimes, but now i can't seem to get one at all.

    Finally called up Google and they eventually switched me to Asus. That killed an hour with useless crap, but at least they do answer the phone. I got a return authorization number in case I want to send it back for them to look at. Both the Google and Asus reps said it's the first time they ever heard of anyone complaining about the gps on the n7 2013. Can you believe that crap!? They must say the same thing 100 times a day!

    Same problem with Nexus 7, Andriod 4.3, Kernel version 3.4.0-g1f57c39 bought in October 2013.

    Could not acquire satellites when wireless location was turned on.
    When wireless location was turned off (leaving only GPS location), satellites were acquired very quickly. Then, after five minutes the display would freeze. Only a reboot would fix the problem. Useless for any kind of navigation.

    O man I just picked up a nexus 7 last night mostly to use in my car for Navigation & spotify now I come across this thread, now I'm not sure if I should keep it or not?

    I really like it so far but if GPS is going to fail it is of no use to me I guess I have 14 days to decide . do you think the GPS problem is an issue for a certain batch of tablets, any hope that an update will resolve this issue?

    It's definitely not a problem with every unit - mine works great, I've used it for extended periods with the Sygic nav app without a single problem. In fact, of the more than half a dozen GPS-enabled devices I own, it seems to get the best reception - I was very surprised to get a signal in my basement with it. You need to give yours a test before deciding one way or another.

    was looking forward to enjoying this saturday first day with the new tablet should of gone to work, i used one of those gps status apps on both the tablet and my galaxy s4. At times the tablet could not even locate the satelites, the s4 never had a problem and , google maps actually works well on it that is what i have been using up until now.

    Google maps wont lock unless i run GPS Test...Or use Wireless network Location. I think its a software bug! If GPS test app locks location how come other apps that require GPS won't lock?! I don't really care about GPS cuz i don't use it on my Tablet. however It is kinda annoying that in order to use GPS receiver "only" YOU have to RUN GPS test app. Reminds me of Verizon's Droid Charge That thing was useless just like AT&T's Samsung GS2 Skyrocket after ICS update!

    I didn't have problems with freezing and rebooting. Have you updated to JSS15R?

    I compared an old and new Nexus 7 in the office. When I was near the window, both had a gps lock and kept it until about 20ft from the window, then the lock would come and go, until about 25ft where neither tablet could get a lock. When I walked back to the window, the old 2012 Nexus 7 would regain the lock where it lost it, at about 20ft. The new 2013 Nexus 7 would not regain the lock until I was almost at the window. I think that this is one of the problems. Once the new 2013 Nexus 7 loses a gps lock, it needs a strong signal to regain the lock. Both tablets had access to the office wifi. The old 2012 Nexus 7 has a Broadcom BCM4751 Integrated Monolithic GPS Receiver Google Nexus 7 Teardown - Features NVIDIA’s quad-core Tegra 3 processor while also sporting 1GB of internal RAM and the option of 8GB or 16GB of storage . I couldn't find a tear-down of the new 2013 Nexus 7 that showed the GPS module, but they switched the Bluetooth and radio modules from Broadcom to Qualcomm, so the GPS is probably also Qualcomm Nexus 7 2nd Generation Teardown - iFixit . I did this testing with the tablets out of their cases. I have magnetic wake/sleep cases for both tablets. The old 2012 Nexus 7 works the same with or without its case, while the new 2013 Nexus 7 shows a weaker gps signal when it is in its case.

    I'm not sure if the initial problems with touch and gps are the fault of Google, Asus or Qualcomm, but the design to place the gps in a place where it is blocked by cases with magnetic wake/lock is the fault of Asus, and supposedly Google will switch from Asus to LG for the third generation Nexus 7 Rumor: Google May Use LG for Third-Generation Nexus 7 .

    The new 2013 Nexus 7 seemed OK in my car using the "High Grade Google Nexus 7 / 7 2 Tablet Robust 360 Adjustable Car Windshield Swivel Suction Mount with Low Profile Car Kit Holder" that I bought from Amazon (plus I installed the Sygic navigation app). The mount is a bit big, but it does not have much metal so it does not seem to interfere with the gps, and it can keep the tablet high enough to get good view of the sky. The drive was mostly on country roads with nothing to block the sky. City driving might be different.

    Just drove two hours with a Nexus 7 intended to be used for GPS. Instead it is a POS. I have build KRT16S and the GPS worked about 10% of the time with reboots fixing it for a short time.
    First Android device and probably my last, I kept wishing I had my iPad that is sitting at home right now.

    I updated to Kit-Kat last week and it broke my GPS. My GPS had been working great with Android 4.3, however, with 4.4, I could not get any lock (with GPS status, Google Maps, Yelp, etc.). I ended up (with some hassle) reverting back to 4.3 (JSS15R), and the GPS worked fine again. Also, I have no problems with my magnetic lock case.

    Interesting, I had exactly the opposite experience. GPS worked fine with 4.3 and would not lock at all with 4.4. I went back to 4.3 for now.
