I got the phone at 8 am today, it's a great phone ( till now) . I tried to use the GPS many times ( I turned off assisted location and just kept the GPS). At my window where I used to get around 6-7 satellite with MT4G , I am getting 0 , nothing in the view. When I got out and tried in the street, while standing I got 2 sat only. So I think there is a problem with the antenna. Any tips to verify if it's really defected or something else, I read about some folks getting locking in few seconds and with 7-11 Sats.
Update: After few hours, GPS started to work just fine. I don't know why but now it's very fast and pretty accurate.
I opened Google Maps 5 and it instantly was locked on me. No complaints there!
Oh ****. I realized I voted "no" because I thought the poll question was the topic title. D'oh.
Ok... My GPS wasn't working for like. Since I got it. But now suddenly, 5 hours later, after I pulled the battery multiple times, and then ran the GPS Test app for 5 minutes, I'm getting locks.
-_-
Works like a champ for me. In fact back to back my Evo and NS seem to be getting a lock at about the same speed, fast.

I will try any crazy steps :d But I don't want to return it, so I hope it works. I like the phone but I love GPS
Now this is weird. It started working now I will test it more and see what happens.

Exactly. I thought mine was borked for good for sure. But no. After quite a few reboots and battery pulls it's working epicly... As is Acquiring Location (wireless location).
Sigh!

I tried now , it locks very very fast and accuracy reached 5 m while walking. This strange, maybe it had to do with the antennas and the back cover? I don't know but now I am happy
It looks like the small handful of people who reported issues with the GPS are no longer having anymore issues. Very good news. If the GPS really is fixed, then I'll definitely be buying a Nexus S when the 2nd shipment comes in.
I'll basically be trading my AT&T 3G for a working GPS. Hopefully I won't regret that decision.
Yea I used my GPS too get home and it locked in with in about 5 to 7 seconds.

I could have sworn there was another thread for this that disappeared. Oh well..
Mine locked to 5m on first try.
Did some heavy testing on the GPS today, and I've gotta say not once was it not able to find me. Only tooks seconds too. I came from the MyTouch 4G, which has a great GPS, but for some reason the one on the NS out performs it.
Very happy with it.
Whats up Will, I was the guy at BestBuy who bought the Nexus S at the same time as you. I agree, the GPS was dead on all the time i fired it up. Found me in seconds. did not have a single problem with the GPS.
I had problems with gps at first try but then after getting the satellites I've managed to get the satellites almost instantly.

The GPS on my Nexus was able to find me just fine a few seconds ago. It took about a minute for it to lock on.
However, this isn't due to any issue with the phone as much as the construction of the building I'm in. Whatever this building is made of seems to make cell phone signals it's *****. I imagine my phone's signal being something like the Gimp from Pulp Fiction every time I walk in here.
That being said, I'm not sure what issue other folks are having, but my GPS was able to find me just fine in a building notorious for dropped calls(to the point where I actually have to go outside if it's a really important phone call), drops everyone to EDGE regardless of carrier, and even butchers WiFi signals 30ft away so I am very satisfied with it.
Mine is working perfect so far. Used it after class to locate a Panda Express. Enabled GPS, opened maps and it locked on to me in a few seconds.
I shall watch this thread closely... I am ready to blow nearly $600 on a Nexus S, but if the GPS works as well as on the Vibrant flavor of Galaxy S phones, I will pass. Because it sucks. Really.
G1: reasonable GPS performance, great wireless signal capture, big bulky and slow.
N1: fantastic GPS performance, horrible wireless signal capture. One day it began dropping calls at home and at my GF's I'd be lucky to get ANY signal at all. Not good for a job hunter like me.
Vibrant: wonderful wireless signal capture, the worst GPS performance I've ever seen.
Nexus S: gonna have to verify, really verify, that people don't have the same Galaxy S GPS problem before I blow a ton of cash since I re-upped my T-Mo contract with the Vibrant and am not eligible for discount.
As for the camera LED flash: I have found it to be most useful when I need a flashlight.

I would assume that the GPS performance is much better than on the vibrant, since they changed the location of the GPS antenna at the very least. It also does sound like most people are not having any issues whatsoever. I was holding off buying one for this reason as well, but I think samsung may have fixed it.
Just so you all know, the first time you use the GPS on an Android phone tends to take longer than it usually would. After that, it should perform properly.
It usually takes the GPS about 15 seconds for it to lock on to me
I've been rocking my Atrix for a few weeks. I was using an Inspire previously and I just wanted better battery life, a smaller form factor (and lighter), and a front-facing camera.
Long story short, I've been testing the piss out of this thing to make sure it's the device for me. I really have no complaints about hardware and I have even learned to live with Motoblur (with the right launcher covering it up).
The GPS on this thing is simply amazing. It locks onto Satellites indoors within seconds, outside instantly. I even got a lock today in my work, which is in a sky scraper. Even my iPhone never got a lock there. This is with Wifi off, by the way.
I remembered from my Droid X that Moto knows how to make a GPS, but it still surprises me how good it is. I compared it side-by-side with my Inspire and my Focus and neither one could get a solid lock in my house and both were off by quite a bit.
Atrix FTW. As cool as the Galaxy S II looks, I have a feeling that the GPS won't be anywhere near as good and then I'd be back to that "too big for one hand" form factor.
yeah i pretty much abandoned my Garmin Nuvi 220W..
in other news ---- anyone want to buy a Garmin Nuvi 220W?
Yes, GPS is super solid and very accurate.
Look at Garmin's stock chart.
i have used mine several times and it is bulletproof!
Moto definitely is the best when it comes to GPS on Android, and Samsung is the worst. Only a Nokia e-series device beats it down (instant lock indoors anywhere).
Oh Nokia, why did you go all "Elopcalypse" and pass on Android...

I had an E71, but I don't remember how good the GPS was. I do, however, remember how horrible it was on my Captivate. Everyone is saying that Samsung fixed it with the Infuse and Galaxy S II, but I'm wary. Even if it's not as worthless as the Captivate, I doubt it would be anywhere near as good as a Moto GPS.
Incidentally, Moto makes a standalone gps. I wonder if it's anywhere near as good at tracking as their phones.
I agree. Just got my atrix last week and was very impressed with how quickly and accurately the GPS locks on. Much better than my previous Nexus One or Dell Streak.
The Atrix GPS is definitely outstanding, but the Xperia X10 GPS is still the best I have seen in any mobile device (standalone GPS included). Samsung is definitely the worst.
I went to the US which for me is a pretty huge deal (the roads in Canada are dead simple and the speed limit is very low). I felt so at home using Google Maps with the Navigation beta. **** was DEAD on everywhere we went.
Aside from when my phone died, it was awesome. Couldn't use GPS for about an hour on the way home because it was so low and needed to charge hahaha... was pretty scary. Was blitzed on pot brownies too LOL
I've got the car dock and I'm amazed by this gps. Sitting at a stop light I can let my car creep forward slowly. The gps is sensitive enough to register this and shows my speed as 1 mph. Just amazing. I took it on a 1200 mile trip, and it performed flawlessly! I love this phone! Definitely a huge improvement over my iPhone 3G. This phone routinely makes my wife and daughter jealous with their iPhone 4s.
I am curious, what GPS software seems to be best for android? I've only ever played with Google Navigation, and it works great.
I also have a Garmin Nuvi 220W that I can't even look at anymore. The Atrix GPS is flippin's sweet! No exaggeration that it's dead accurate. Traffic updates are scary good, even on sideroads in my area. I use it in the car dock for my daily commute, to get me ahead of the traffic curve. I thought it was off yesterday because there was no way it would take me 30 minutes to drive the last 5 miles home. Alas, the streets were flooded along a creek, and it told me precisely when the speeds would pick up again, so I stuck it out. +1000 internetz to Motorola for the GPS.

Coming from a Nokia N810 (it had a GPS), I like the Atrix GPS. It's very accurate and locks super fast.
Though I wish Google would have a vector based map, as I don't want to consume a ton of data as I drive to Colorado next week...
yeah its amazing, perhaps something weird happen to me Stock take more a really more like indoor 2-5 minutes, ouside like 1 minute but i flashed telstra radio from MOD to enable hspa+ and WOW amazing instant almost i didint believe this but its really amazing

So how, if at all, will the move to Skyhook affect the Atrix? Think that will just affect future Motorola devices?

First use outside, took about 20 seconds to lock in.
Second time, about 2 seconds. Inside, it locks in in about 30 seconds. Locks on about 18 satellites, which is about twice the number epic touch would lock in inside.
Haven't actually tried navigation yet.
averaging about 3 seconds inside and outside, here in nyc
Locks on much better then my old Epic 4g(non-touch)

Actually, it makes very good sense to do some baseline GPS testing with another device so you will have some benchmark. Most people here are just reporting lock times, which is just a threshhold metric that shows if the GPS works at all.
Another thing that is useful is to do some comparable tests of actual accuracy (not just the imputed accuracy reported in GPS Test) by running real-world tracking tests on identical courses. It is even more useful to include both driving-course tests and walking-course tests. Use the My Tracks app to capture these tracks and upload them to your Google My Places, which overlays the captured tracks on maps. Then you can view the before-and-after tracks, and even post links here.
Then you have an intelligent answer to the question of how well the GPS works.
I was INSIDE of a restaurant last night and did side by side GPS lock test on a GS3 and epic touch 4g.
GS3: almost instant lock and about 15~20ft accuracy
ET4G: never got a lock until we were done eating and left the restaurant.

I've used navigation about 4 times since I had it and it works and locks in seconds pretty well. Just as good as the EvoLte. I had the EvoLte for about 3 weeks before I switched to the S3.
I was wondering if anyone who has both the GS5 and the GS4 has compared the accuracy of their GPS positioning using something like Google Maps to determine if either is closer to the actual position as shown on Maps? My GS4 doesn't seem to indicate any closer than about 30-40 feet of my actual position under a clear sky. This is sometimes a problem when driving along the freeway where there is a street running parallel, and Navigation tells me to make a turn where there is none, and vice versa. I am thinking about upgrading to the GS5, and was wondering if there is an improvement in that unit's GPS system.
My neighbor has gs4 I have gs5. His accuracy is 10 to 5 metres. Mine often goes down to 3 metres. Also lock is faster.
Same with and without mobile data. No modification on both devices regarding gps.

The S5 processor, the Snapdragon 801 uses the gpsOneGen 8B GPS module. While the S4, I believe used the earlier 8A iteration. The S5 GPS is said to have faster locks and be capable of 2M accuracy as well as support for the Chinese constallation.
Keep in mind that performance is quite dependent on firmware, making even head to head comparisons challenging.

Hey all. I was wondering if anyone heard anything about the accuracy (or simply how well it works) of the Note 4's GPS. I remember my Note 3 would drop location repeatedly and it would annoy the crap out of me while I was on my motorcycle. It was really the only reason I got rid of the N3 for my One M8 in the first place. I needed that reliability for my "adventures" . If the GPS is rock solid on this new Note, I will be making the change back. Any info uncovered or indication that it is improved would be much appreciated. Thanks!

I was frustrated with the GPS on the Note 3 as well. Couldn't get a decent lock while I was using it in a sports armband while running though it was much better if I held the phone in my hand during the runs. (not the most comfortable thing given the size) Finally took a look at a schematic to find out where the GPS chip was located. Turns out it is on the back side of the phone near the camera. So, it is blocked very well if being used in a sports armband as the back is generally pressed against your body that way.
Not sure where it was on previous devices, but either it was closer to the edge or the chip was better..
hope they realized this and did a better job this time
All antennas sacked on my Note 3. GPS wifi and network signal. Really hoping new antenna breaks in the casing of note 4 helps.

But my Note 2 refused to point the right direction in Google Maps. The little blue arrow was always randomly wrong, really annoying. I'm told it was a compass problem and not the GPS. (Thats why navigation worked so well, it uses GPS rather than the compass). It is, soon to be was, really annoying.

TL;DR?
Googled myself silly trying to find this out and failed. I don’t think there’s an easy answer to this until someone buys both variants of the Note 4 and tests them out. Samsung is famous for having a whole bunch of variants per product model, as will be the case for the Note 4, so it depends:
Which SoC you get (Exynos or Snapdragon, as was the case with the Note 3 too). They come with different GPS solutions deep down.
What was done with the GPS antenna, and how well various tweaks were done to phone and radio firmware, which can also be carrier dependent and make your ‘mileage vary’ for things like A-GPS – pun intended :silly:
From what I've read, the Exynos version of the Note 4 might have the most room for improvement (or regression) because it’s incorporating a newer generation GPS hardware chip, but the Snapdragon version already incorporates a tried and well tested GPS hardware module. (Maybe look for a review trying to comparing GPS accuacy on the S5 Snapdragon vs. S5 Exynos to suport or debunk this point)
General notes about smartphone GPS on Android
Before getting into what I deem a plausible explanation of why Samsung GPS solutions are hit and miss, a brief general note about my understanding of GPS smart phone operation. From what I've read, getting a GPS fix and keeping it, with reasonably accuracy has a whole host of complicating factors. Some of them are:
GPS hardware and software in phones is probably optimised for 1) low power consumption, 2) time-to-fix and 3) accuracy, where accuracy is the lowest priority. So it’s likely to disappoint, but a less accurate GPS is better than no GPS (device with no power left)…
Sounds like A-GPS can matter a whole lot. Is A-GPS actually working? This depends on 1) signal coverage, 2) reasonable data connection, and 3) phone’s firmware properly configured to use A-GPS. Some people claim flashing different radios (often related to different carries or regions) improved or degraded how reliable GPS was. So it’s possible the GPS hardware is okay, but the radio/mobile operators setup has borked A-GPS implementation. And maybe A-GPS would help not only getting that first fix fast, but also helps to quickly recovering from a lost satellite lock when in a jungle (concrete ones and natural ones, given tall buildings and trees mess with GPS signal).
Determining a location can also rely on complex algorithms with even more inputs. Speeding up finding a location uses A-GPS, mobile network signal and wifi-signal (with triangulation). But keeping a lock and 'smoothing' out your location can use extra inputs from accelerometers, etc to compensate for and compliment the inaccuracy GPS signal readings.
Substantiating the above claims
GPS could work well for some Note 4 variants and not as well for others? What GPS solution comes with which SoC? In summary:
For the Snapdragon SoC variants of late, Galaxy S5, Note 3 and Note 4 share the same GPS hardware chip component design within the Qualcomm 800 series SoCs, so there probably won’t be any GPS improvements coming from this SoC… If we’re lucky, maybe antenna placement or firmware improvements were done, but otherwise, we could be in for more of the same (as I detail later, Snapdragon SoC’s GPS should be decent).
For the Note 4 Exynos 5433 version, a discrete GPS module is provided by Broadcom. This was the case also for a Galaxy S5 Exynos variant? Could this one bring some improvements?
I believe the Qualcomm GPS hardware component in the SoC is unlikely to be a major cause for concern, and the differences will come from the phone vendor (Samsung) specific build and/or the carrier/network operator specific radio firmware tinkering and support of location services.
Based on my own interests and experience
I’m also super keen to see an answer to this, as I'd be interested in getting a Note 4, but not if it has the same woes with GPS as my Galaxy S2 has. The S2 has multiple posts complaining or offering various hacks to try improve the GPS. And before that, I read the S1 had a particularly poor GPS hardware. After the S2, I think the Note and S3 started officially supporting GLONASS, which in theory gives the newer models a larger set of satellites to grab a fix from. But hearing the Galaxy Note 3 also has some GPS problems makes me worry that GPS is a neglected topic for Samsung (assuming the Note 3 you complained about was a Snapdragon version)… Assuming it’s not Qualcomm, it’s either Samsung or the carrier/mobile operator’s radio firmware at fault.
If Samsung messes up the antenna placement (as I saw alluded to in a previous post), it may not matter that much which SoC/GPS solution is beneath it (Qualcomm gpsOne Gen 8B vs Broadcom BCM47531). Antenna location and interference can be a serious issue. For example, my old disastrous Nokia N97 had a defect where the GPS antenna wasn’t properly shielded from signal interference of nearby components on the PCB and I was tempted to throw the device out of my car most of the time I tried to use GPS!.
If your carrier writes dodge firmware or has crappy network support for A-GPS, it’s going to take long to get an initial lock. Here in South Africa, I’m pretty convinced my carrier/mobile network operator MTN, or ‘<empty>N’ as I like to re-brand them, could care less about how well my GPS works. Sometimes with MTN I’ve got a full 3G signal with ping latencies of more than 30 seconds and no hope A-GPS can even talk with the servers it needs to reach
…
More details about which Variant has What GPS pieces, etc?
For those who like the tech details and background, I did a fair bit of Google digging about the S4:
GPS is integrated into the Snapdragon 805 SoC, but it not integrated into Exynos 5433 chip.
Snapdragon 805 has iZat/gpsOne Gen 8B with GLONASS support (www<dot>wpcentra<dot>com/snapdragon-805-processor-at-CES).
For all previous Snapdragon 80x’s, the GPS chip hardware component design is the same Gen 8B. Snapdragon 800 and 801 were used Note 3 and S5 variants respectively.
Qualcomm are tried and tested? Given Qualcomm are 1) the market leaders for providing low cost integrated GPS chipset solutions, 2) probably have the same lineage of GPS components delivered in iPhones (via the LTE modem chipset apple gets from them) as well other Android vendors who used the Snapdragon SoCs with GPS solutions integrated. If there are any issues on the Qualcomm GPS module design, it’d be a very wide-spread problem… (www<dot>qualcomm<dot>com/products/izat claims 3 billion devices use iZat tech and www<dot>anandtech<dot>com/show/8004/htc-one-mini-2-review/10 shows this GPS played well in an HTC. QUALCOMM claims it gets as good as 2m accuracy)
Dedicated GPS for Exynos 5433? Broadcom BCM47531 (www<dot>techinsights<dot>com/teardown.com/samsung-note-4-galaxy-alpha).
Broadcom BCM47531 is the new kid on the block that claims to support more Satellite constellations, but millage will vary again, as I’m not sure those extra constellations are going to help yet given some of them are being developed or are region specific (www<dot>zdnet<dot>com/broadcom-announces-new-five-satellite-constellation-location-chip-7000024098). American GPS and Russian GLONASS are the only fully fledged online GNSS (Global Navigation Satellite System) solutions to date and the Qualcomm chipset already supports them as well.
Recall reading Broadcom have 2nd place in market share behind Qualcomm.
My suspicions of why Samsung GPS is hit and miss (Samsung’s history is quite spotted)
With Samsung pushing so many other sensors and features, several of which seem gimmicky, I worry that core use cases like navigation with GPS accuracy isn't the best implemented and tested feature… Kudo’s to Samsung for innovating, but I wish they’d also push more for refinement of important features/sensors that need to work well.
Another important consideration is that fairly testing and comparing GPS accuracy is difficult and time consuming. Benchmarks for CPU and GPU are easy to perform and repeat and other comparisons, while a bit more effort, such as screen quality, photo/video quality, or audio, which can be done in a lab with measuring equipment, etc. But testing a GPS usually requires going outdoors and driving or running / cycling around in various scenarios and places, and comparing the GPS track/results to a very well-known path or the track of professional grade highly accurate GPS device.
Maybe Sammy is smart and knows GPS is not easy to test and compare like other smartphone features, so they don’t focus on it that much? Hence it’s hit and miss between models and variants?
Some sites have aimed to try measure and compare phone GPS accuracy, but nothing I’ve found has a big/accurate enough sample. E.g. gpserror.azurewebsites.net only has a handful and test methodology is questionable? Please share if you happen to find a better example for this, as I didn’t look all that hard to be honest.
Interesting post. Question: did you research satellite coverage for S Africa vs US or Europe (in contributing to speed of lock, strength of signal)? I've always had great gps on my Note 2 but I'm in California. (I use it for golf all over and it's fast and accurate to a yard. Travelling in a vehicle only issue is when on a highway travelling fast, google nav sometimes gets confused and thinks I'm on a side street bit then correects itself a couple seconds later). I'm getting the Note 4 next Mon and I had hoped it would be at least as good.

I am very curious to know this issue as well.
My phone history has been an unlocked Telus note 2 (same as at&t model) for the last 2 years and have never ever had any problems with GPS losses. About 3 weeks ago I bought an unlocked used bell version (same as at&t) 4 month old Note 3 for $400 and instantly noticed the loss of GPS coverage on a regular basis. I'm ready to throw this thing out the window and pay to go up to a note 4 but NOT if it has the same GPS issues. I'll pull out my note 2 again from my desk and just keep using that.

I didn't research the geographic difference between South Africa and other regions, but noticed that my iPad 2 is much better with Navigation (using Waze) compared to my Galaxy S2. And on my S2, I also noticed Waze gets confused and jumps around to onto different streets, annoyingly often in fact. It also struggles more the faster I'm going.
But my S2 setup is miles away from what one can expect on the Note 4. The point was that in my esteem, the S2 GPS was improved compared to the S1, but still quite inaccurate and unreliable (depending on other factors like the ROM/A-GPS, etc). So I was sad to hear people had issues with the Note 3. It was part of a weak inference that perhaps Samsung doesn't prioritize testing and refining the GPS accuracy as much as we'd hope for... It's much harder to do than ace CPU/GPU benchmarks.
Seeing the various other folk post about how the GPS worked well for one variant and carrier combination versus another affirms my estimation that it may be hit and miss for the Note 4 too - and many of the variables like the carrier specific ROM and plus a the reliability of the network supporting A-GPS will be a significant factor over and above the base GPS hardware stack.
Bottom line question: Can we reasonably expect consistency in the Note 4 line up (independent of carrier and variant)? I'm betting not.
Yup, my Sprint Note 4 (910P) can't lock my location inside my house, whereas my S4 had no problem.
I also noticed that it dropped mobile data in spots on my drive home yesterday that my S4 was able to hold.
No case yet on my Note 4 either...
Note 4 on Tmobile gps not good
So i recently gave up an iphone 6 plus for this note 4. Before that i had an htc m8 and lg g3 and one plus one. I did not have gps issues at all with any of these. I had a gs5 which the gps sucked. The note 3 was horrible too. This noye 4 gps is terrible. It will not pick up the direction im going. Often times thinks im going backwards. When it does work its brief. I am very worried and uncomfortable using the gps in this phone. I cant afford these kinds of glitches while doing 65 - 70 on the highway. I travel a lot for work and this isnt reliable. Im going to be returning this phone and switching to the Nexus 6.
Nexus 6 better alternative? Lets hope we get a review of the GPS

Thanks for the feedback. Sounds like other vendors did a better job of their GPS integration (might be easier when not trying to tack on so many different features and sensors, etc). Also waiting to see Note 4 vs Nexus 6 GPS.
thank you butternutty for digging all these gps related details. i'm also waiting for some more in-depth reviews on that matter. just to confirm your thoughts on past devices, my experience with the predecessors weren't pleasing.
during 6months i checked the accuracy of a note 1 & a note3 next to each other w/o a-gps (as you would use when travelling abroad and avoiding roaming charges) with the following apps: gps test+ & gps status. roughly 3 times a week while travelling by car between 1 to 3hrs. the note 3 (qualcomm) was far worse than the note1. loosing fixes and badly inaccurate (12-17m in average) within cities, out on the open and anything inbetween, as well as in different weather scenarios i.e cloud coverage. i used 5 different note 3 devices during that time period and 2 note1. btw, i also checked it on a bike, walking, as well as on different continents and have used "professional" gps devices before. these results plus the annoying compass calibration issue (after each start, so basically every morning) resulted in me selling the note3.
it's a pitty, because i like & use the stylus on the note line. thus i thought the note4 would cure some of these problems. reading in the forums the experience of early adopters, it seems, that we're facing again compass calibration issues after each start (not an issue on the note1) and the gps w/o a-gps doesn't seem to be very strong or is on par with the note3. so basically no changes as you stated.
depending on which region you live, you get the qualcomm chip and have to pay overprice to get the arguably better spec'd n910c with exynos because it seems it uses hopefully a better broadcom gps, cat6 bands, (if i read correctly) a wolfson chip a/d sound converter, uses probably (i'm not sure-just stating the experience of others in this forum) an isocell cam with pdaf and therefore faster autofocus like the s5 and not what's found on the qualcomm which uses sony's imx240 chip and it's contrast detection. moving along comes the issue with lollipop & 64bit, which should be "available" on the exymos version in 64bit if sammy releases it or "opens" it from 32 to 64bit. even though the discussion on 3gb vs 4gb ram using lollipop in 64bit will follow. all this puts the buyer in a situation in which he's uncertain if he got the "right" note4 version.
sammy, quo vadis on the note line? imho they should start concentrating on quality sensors instead of adding new ones. is qualcomm's 810 the answer? will it be rootable? wait another year? every year and before the launch i fall for all the hype of what we should expect specwise/ supposed leaks. once the device is officially introduced, we supposedly didn't get this or that specific because time or manufacturing process or whatever were an issue. but by the end of the day - as in this case with the note4- i'm a little disappointed that such and such item didn't make it in the final draft (e.g. ip 68).
hope to read more gps real life experiences of either qualcomm or exynos note4 users here.
p.s.: reading thru the posts here, i hope it's clear, that i'm not talking/writing about car navigation software (e.g. tomtom/sygic) which corrects via likelihood calculation your position and puts you on the next available street and therefore doesn't indicate your real position but your "expected" position in accordance to the navigational map/grid and where you "should" be.
I've got the 910F and gps test shows the accuracy at 3m and I'm indoors. Google maps places me inside my house. No complaints when navigating.

I usually get a "3d" lock and 10 feet accuracty within about 10 seconds on mine. Im using GPS Test for this.
Here's a Video, I Just made.
