Is anyone concerned on whether or not the phone will have issues locking on to your location? I currently have a samsung droid charge and the thing takes minutes to lock (talking 10 to 15 minutes at times). I'm aware samsung has had faulty gps with the first galaxy series as well, but haven't checked on their latest phones recently. Anyone know if the nexus s had any gps problems? Just hoping this phone won't suffer from the same problems as those other phones.
The built in barometer sensor will probably help.
Here's an article published by PocketNow:
Google Confirms Barometer Intent: Faster GPS Locks
According to Morgill, the intended use for the barometer sensor will be speeding-up GPS acquisition. We had mentioned the ability to gauge altitude via barometric pressure, but focused on its use in estimating altitude independently of GPS, saving battery life. Instead, Morgill says, it's to make initial GPS calculations go faster.
While it's easy to keep-up with GPS satellites, an initial lock-on can take a smartphone's GPS receiver a little while to make. Besides needing to wait to receive satellite constellation data from the GPS birds, the receiver needs to solve a complicated set of equations to figure out your location. One of those values it's solving for is your altitude coordinate, and if you already have a pretty good guess what it's near, you can speed up the rest of the equation-solving. Of course, you always could use the sensor for any of the uses we mentioned, given the proper app support, but this GPS-assist looks to be the primary motivation for the sensor's inclusion.

Even better would be to know that it uses the Russian Glonnas system as well as the US GPS sats to give double the number of possible sats to lock to. The Samsung Note uses Glonass and the Apple 4s uses both. Let's hope the Galaxy Nexus does the same.
I am hoping that after more than a year and over thousands of complaints Samsung got their act together and got that damn GPS working like HTC's devices.
The gps lock seems pretty quick judging from this video http://www.youtube.com/watch?v=o-yWgzoJXMA#t=9m41s
Nexus s zero GPS issues full stop!
Sent from my Nexus S using XDA App
The Galaxy S debacle gave Samsung a black eye they won't soon forget. Whatever the issue was though, it was solved when I got my NS about a week after launch. It locks usually in less than 5 seconds and has only lost signal a few times and has never failed to function for the nearly one year that I've been using it.
Yeah this was the only thing stopping me from pre-ordering the galaxy Nexus.
My Galaxy S Vibrant (T-Mobile) has a though usable GPS, it's complete garbage.
I remember driving down I-5 on my way down to Portland... it kept jumping in between local roads and the actual I-5.....
So I take it that GPS is fairly fast to lock and accurate? (keep in mind I don't use A-GPS since I have very limited Data)
very quick GPS lock and accurate from my attempts so far
Just stood outside in an alleyway between houses and got a lock in under 10 seconds !
Yeah mine has got pretty good GPS performance, although coming from a Galaxy S anything is better.

It literally locks in 10 seconds while outdoor and 20 while indoor. Really works well

Has there been any confirmation that galaxy nexus can use GLONASS satellites?
I've had no problems with gps so far.
sent from a galaxy far far away.
tested it right after the buy. i am a geocacher the fix was instant. Much faster than my Desire HD
Droid Charge (my dad and sister has one) can take several minutes or longer. My Motorola Triumph could take 5 minutes out in open area (pathetic)
Nexus, locked within 5s from within a bathroom first time ever using it, down to 10M accuracy.
Needless to say, I am very unhappy that it wasn't instant but I suppose I can live with 5s
Off Topic, I read that the galaxy note uses 3 different GPS systems, US/Russia and something else, so it's able to see about double the sats in the sky - anyone know if nexus is the same way?
How is the wifi performance?
Has anyone tested the download/upload speeds?
Also what is google navigation like? I use this quite a bit and my old htc desire is good for navigation.
Thanks
Im finding the wifi performance to be much better on my note 2 compared with my note 1 im getting a stronger signal in all rooms around the house. I havent tested the gps yet.
Sent from my GT-N7100 using xda app-developers app
I can confirm the stronger Wifi signal. Much better than my previous devices (Galaxy Nexus, S3 or Note 1 for example).
GPS looks also very strong, but I was not able to test this properly.

Stronger then the S3.
I get strong wifi in my house in places where my S3 cant even pick up.
GPS so far seem quick on locating a fix.
hi boys.
I'm using civato rom and kernel on my n5100 but with stock too I have a weak wifi signal.
my wifi reception is weaker than my Samsung galaxy SII.
I'm crazing.. how is possible that a new device could have a weaker wifi signal than and old one?
sometimes I lost wifi reception or it is slow...
do you notice this problem, a not so good wifi module?
any solution or suggestions?
thanks a lot!

The solution is to improve your router or improve the positioning of your router. If you're on public wifi, try to get closer to the source. While mobile devices all suffer from weaker wifi reception when compared to laptops of desktops due to power consumption compromises, there is nothing inherently wrong with the Note 8.
If your router is buried behind the monitor or is otherwise obstructed, you can significantly improve signals by just moving it to a higher and unobstructed position. If you have a garbage router, you'll get garbage signal. Garbage in = garbage out.

my galaxy s2 has a better wifi signal than note8, how do you explain?
do you notice a weaker signal in your note in comparison with your smartphone for example?

Don't look at the signal bars as a hard indicator. They are just a graphic representation of thr signal strength or signal to noise ratio. What that means is 3 bars for example is a range and not a single number. What it also means is that it's a subjective reading. For example, an AOSP ROM may display 2 bars for the same signal strength as touchwiz that displays 3 bars. So get an objective measurement. Either find an app that willngive you the actual signal to noise ratio, or simply run a speed test. If both phones test similar, it makes no difference how many bars they show. Of course there may be minor variations in each device as far as reception goes, but it should be similar overall.

thanks sputnik.
obviously I'm speaking after many tests.
With different wifi analyzer apps the result is the same.
In areas of home in which my tablet has more difficulties his signal is around 10 dBm less than my Galaxy S2. (for example note8 84 dBm vs 72 galaxy s2)
For this reason I'm telling you that I'm not happy of its wifi, I don't know if a hardware problem and if bringing it to Samsung assistance.
what do you think, can you do similar tests with your smartphone?
Thx!

I ran a wifi signal app on both the Note 8 and my Galaxy S4. I don't have an S3 to test unfortunately. The results I got were similar, 69 vs 67 dbm respectively. This was far away from a low end router. Before you try to get service on your tab, try the comparison with a different router, such as friend's or a public hotspot. Lets rule out your router as the reason for the signal drop. Maybe your phone can better handle a weaker signal or has a higher power wifi module or better antenna.

i took a time to test my wifi
my note 8 wifi is always around 10 dBm less than my Galaxy S2.
it seems a sort of shield, or obstacle that covers my wifi module
i don't know if it has a weaker module or an hardware problem, but I'm asking to myself could be differences between different notes 8? i don't think you have problems who i have...
i don't know if samsung assistance could fix my problem or joke me
thx for your help!

I also notice this problem, my old S6 Edge+ has no issues with wifi in 1 room of my house, the Note8 sometimes completely fails to download web pages in the same room.
Can anyone test the GPS accuracy using GPStest apk the only dual GPS app compatible for now. We want to know if it's 10x more accurate then other phone or only bull **** like xiaomi mi 8
Bumping this question up... I'm really looking forward to hearing how accurate the Huawei implementation of "dual frequency" GPS is.
For many people in the US...the extra accuracy is NOT a problem...... However, in downtown Tokyo or Manila....after you've walked around the block 3 times while following G Map's "bouncing blue GPS dot" in 35 degree heat / 99% humidity...accurate GPS *is* a big deal. To recap - the dual frequency should minimize reflections of the GPS signal and in theory lead to 30 cm accuracy.
NOTE- only a few cities worldwide are served by dual frequency satellites at this time. Where you do the GPS accuracy checks will matter. For more info on the precision of dual frequency GPS...see this cute demo. Can't vouch for its accuracy: https://www.youtube.com/watch?v=mI0TdX7HCwU
I'll try in a little but I can tell you it locked near instantly in my garage where I can't even get xm radio..
Edit:
See a ton of EU, US, and Russian Sats and a few chinese
What exactly am I looking for to tell you?
Thank you for your reply! If your location is served by the dual frequency satellites..... when you enlarge/embiggen/zoom in with G Maps....your phone SHOULD be able to tell you when you've moved from one parking space to the one RIGHT NEXT to the first one. In other words...in theory, there is 30 cm (12 inch) accuracy for your position....NOT the current 3 to 24 foot "radius" of error that current consumer smartphone GPS provides. For USA drivers this will be a big help because it will give you "lane level" accuracy. This is doubly important b/c in large cities with skyscrapers and multi level expressways, there are tremendous problems with reflected/bounced signals and the infamous BLUE DOT may or may not be anywhere near where it says you are...
Downside is that accuracy can be so good...if nefarious actors want you....they can land a drone on your head.. instead of just "nearby" you.

I went outside and the radius around the dot in maps became very small. Walked to one side of my driveway to the other and the dot matched me near perfectly.
Your results are encouraging. Thank you for checking. Hope we can get more input/feedback from other users to find out if this "dual frequency GPS" feature is as valuable as it is purported to be.
Better but not cm accuracy
I have compared my mate 20 pro to Samsung s6 and yes the dual GPS improves remarkably. Using two different GPS. Testing apps I had 3-4m accuracy with mate 20 pro versus 4-9m with s6. It picked up a few more satellites but more. Importantly it was very fast to get a lock. No waiting 2 minutes. A lock was within 2 seconds.
Still I've not been. Able to see any sub metre accuracy yet. I am in the southwest UK.
Maybe GPS Test app will help? ^^
I did using Mi 8 and OP5 for a short period of time, the Mi 8 got 4mts-12mts sometimes, the OP5 got 16-40mts sometimes, the differency is big, didn't got my Mate 20X yet, but soon i'1ll have it
I'm from Brazil

Thanks to all for getting this info out there. KInd of disappointed that once again, the accuracy & precision is much less than what was advertised. Nice to have the speedy lock but would be much nicer to have the speedy lock, accuracy and precision..
Huawei also <ahem> stretched the truth about the Mate 9 being able to use Galileo GPS for accuracy. Everyone using a Mate 9 could not report good news on getting/using Galileo sats or any better accuracy that any other no name phone.

Actually, there are 2 apps with the same name on PS
- GPSTest (this one support dual-band gps)
- GPS Test (blue circle icon with dots inside, doesn't support dual-band)

Would help if everyone posted what city they were in so we know which countries and which cities are are capable of taking advantage of this new dual GPS service
I have no clue to most of the numbers, just sharing what I've got in Singapore.

Switching from Mate 10 Pro, I found that my Mate 20x GPS is less sensitive. Indoors, Mate 10 Pro picked up GPS faster, while mate 20x took longer for a fix and lost location more often. Little disappointing, but it is what it is.
Outdoor, Mate 20x gets more sattelite locks though.

I know that my LG v30 is horrible for GPS lock. Takes 3 minutes usually.
Mate 20 x takes seconds.
I'm in the USA
Very bad gps location when using Huawei built-in camera, even in open space. 50-150 away from actual location.
Accurate GPS location when using other apps, such as GPS Status, UltraGPS.
With the ToF sensor and the 6DoF SPen, I was expecting an announcement for an update to the GearVR. The AR capabilities were shown to look viable on the new hardware, maybe I need to get the dremel out again to make it fit.
Sadly, seems unlikely
