Ingress and GPS lag/uncertainty - Asus Transformer TF700

Has anyone experienced very bad Ingress performance while using this tablet?
On top of that, has anyone experienced incredibly bad GPS lag and/or position uncertainty? I've had times where it stops moving for a minute or more, even when I end up being a block or more away (in my small city, so no sky scrappers or any large buildings blocking the GPS signal either). It's getting to the point where Ingress is a lost hope for the tablet, which it wasn't when I was using my Nexus 7. It actually ran it much better than the TF700, surprisingly.
I've noticed the same problems in google maps and other various GPS programs as well.
Help?

No, I haven't noticed GPS issues. In fact I use my tab to navigate across Europe. Never had an issue. (other than the usual 'below ground or not enough satellites in range')
Then again I haven't tried Ingress. And I disabled Google Maps on day 1. It eats battery even when asleep! Also, that thing won't even work properly on a PC these days, my SGS3 can't find my position at all (let alone load the map itself) and frankly there are much better navigation apps available. (I highly reccomend NavFree.)
Are you sure it's not just a lack of signal strength?

It could very well be a lack of signal strength, but how would I even begin to know that? There's not really an indication in any application what the signal strength is for the GPS.

I am having trouble with the GPS in the TF700. This morning it spent the whole time I was driving around (even tried tethering it to the iPhone) searching for a route.
It seems to me that it was sharper before this latest CleanRom update (CROMI-X 4.6.4 - 10.6.1.15.3/US DEODEXED).
Anyone have some insight? #GPS

Why the hashtag? This isn't Twitter.
It has recently been taking ever longer to find my location. Used to be it could do it in about a minute, now it takes almost 30. I didn't change a thing on my system, not even an update.
There has been an increase in solar activity and geomagnetic interference over the last few months.
Phones and 3G enabled tablets do not have this issue, because the Internet signal is already tracking your position, making it easier to triangulate. (Try turning off 3G on your phone, it'll take equally long.)

Thanks - Understood

HASHTAG from copy G+
Thanks for help.

Honestly, I gave up on it.
MY TF700 isn't really good for Ingress anyway. There's way too much lag involved, and for whatever reason every now and then the GPS just seems to stop functioning. I don't really know why, it just stops at one location for about 2 or 3 minutes. I won't even bother getting into how inaccurate it is.
And just to note, this was before the increase in solar activity.....the solar activity just makes it even worse now.

Any problems with the GPS on the captivate?

Hi Guys,
I've been hearing about lots of problems with the GPS not picking up low SNR satellites and the GPS being wildly inaccurate on the samsung vibrant and also the euro variants of the galaxy s.
Does the captivate have the same issue?
Its true. I bought it on sunday an notice that issue. Hope there will be a update(Bug fix) soon.
Compare to my G1, the Captivate take about the same time to lock and GPStest says the SNR is better. I'm happy with it.

Define Wildly inaccurate. On my Captivate it is dead on (within 9 feet)
I am having major problems with GPS. I am getting a lock but only within 50-75 feet. It isn't good at all. The GPS is slow to update and throws me everywhere.
I amthinking of returning the phone if Samsung doesn't make an announcement about s fix for this.
dial this from your phone:
*#*#1472365#*#*
Change startup from hot to cold.....worked for me. GPS locks much much faster
What are the settings on your phone Citznfish? My phone is off by anywhere from 100-500ft. Thanks!
Ok, I tried it again... In the house I'm about 500 ft off from where I really am and placed in a golf fairway. Outside I am FURTHER off: I'd estimate at least 5 blocks and placed in the middle of a different golf fairway. For comparision sake, my wife's iPhone 3Gs has her within 10-20' while inside the house. To me, this is unacceptable and a great cause for concern. What can I do???

I'm having the same problem here. My iPhone 3GS GPS responded way quicker then this phone does. I have a Weather Channel widget up, and it doesn't find the location to display the weather for a good minute and a half after. Same goes for using Google Maps to find my location. Lot of times it says, "Your location is unavailable." I even tried switching the startup from hot to cold, and that didn't have much effect either.
When I was driving today, the GPS locator had a bad lag in it, I would be down two blocks before it would catch up, and I live in a 3G area, and not a giant city like NY or something.
I wonder if it's because it's so bloated with Samsung UI on it, or if it's just the a bug. Either way, if I'm still having issues with it, I'll see if AT&T will exchange it out for a different one. Otherwise back to the 3GS, which I really don't want to do since I'm loving Android right now.
What does hot start and cold start do?

Hot Start - The GPS receiver remembers its last calculated position and which satellites were in view, the almanac used, and the UTC Time. It then performs a reset and attempts to acquire satellites and calculate a new position based upon the previous information.
Cold Start - The GPS receiver dumps all information and resets. It then attempts to locate satellites and then calculate a GPS lock. This takes the longest because there is no known information. The GPS receiver has to attempt to lock a satellite signal from all of the satellites, basically like polling, which takes a lot longer than knowing which satellites to look for.
Danm a cold start sounds like it would be slower. I tried it and I still can't get a lock within a reasonable range.

I've been reading online that the Galaxy S got a firmware update that greatly improved/fixed the GPS problems we are experiencing. I can only assume that we will have to wait as well for this firmware to completely fix the gps issue.
Try the fix/workaround in the Vibrant forum.

i havent had too many problems with GPS here
Google maps usually locks me in a few seconds
Third party applications can take much longer, however
The problem might be the way the third party apps utilize the GPS

Actually that isn't a fix at all. It makes locking onto satellites much faster, but nothing to address the sensitivity issues, and there is definitely an issue. I 'found' 9 satellites, but could only lock onto two of them, for a few seconds at a time, then back to zero, out in the open.
Hopefully a software fix is on the way.

This fix did help me so now i get a quick lock...as ling as i dint start moving around. It stays close enough to exact to use for driving around but not more accurate than that. The problem isn't really getting a lock so much as keeping it.

Well, I change my mind. While what I said still stands, I've since found that the GPS and the Compass don't track very well. I tried find a geocache using the same GeOrg software I use on my G1. The location seemed to be stuck as I was walking. From my experience with the Tilt, I'd say the GPS is running in "Static Navigation"
The clock is ticking, GPS has to be fixed in 28 days, or the phone gets returned.

I was having problems w/ GPS on my phone as well. Would be way off in Google Maps, Navigator took forever to lock, and geo-tagging photos was also way off. I did something similar - dialed the code to get to the GPS settings. However, all I did was turn Skyhook to ON and switched configuration from manual to auto. I don't seem to have any problems between yesterday and today. It locks incredibly quick and is very very accurate.
Some of you should try this method and see if it helps with anything. Good luck.

GPS Problems? Yup everyone

http://free-pc-guides.com/news/first-att-samsung-captivate-owners-report-problems-with-gps-02887
This is such a sensationalist article. There aren't any problems with the GPS. You're supposed to use a GPS outside, and even inside, mine got a signal fine.
This article also says that T-mobile is expected to get the Captivate, which is false. It already has the Vibrant.
What GPS Problem??
No problems for me, thus far...
Mine has locked once. After that it refuses and just triangulates using cell towers and accurate within 2600 meters.
I'm not sure I would call it a "problem", but the GPS chip in these things is definitely not as good as the GPS chips in most other newly released phones. It could be a software issue, but I doubt it. The Aria would consistently lock onto twice as many satellites as this thing. When driving near large buildings and under bridges I sometimes lose a lock and Google Nav jumps around, which never happens in those same places with the Aria.
It seems to be working fine for me, but then I saw that someone had posted a fix for it when you dialed into the GPS settings, so I did that, and now.... it's still working fine!

I've recently used both an Evo and an ATT-band Nexus One. I do have to say that the GPS on both of those seemed to acquire signals from satellites much faster than the Captivate, and give a more accurate location. Even standing outside, in the open, this one never appears to lock in on my precise location as well. I realize that's only anecdotal, but I no longer have access to either of the other devices.
Maybe its just mine, but I traveled over 300 miles today using Google Navigation, the phone up in the dash, with a clear view of the sky keep on having issue finding me.
I have an N1 and Aria, neither of these have these issues.
Do the specs indicate which GPS chip is being used? Some are better than others. Is it SirFStar III, IV, or MTK or what? This can certainly make a difference but costs about the same, so why get a cheapo chip? Hope Samsung did not do that.
GPS is definitely poor. From watching GPS Test I'd wager it's a firmware issue. No reason to have satellites popping in and out of view in the middle of a field on a clear day...
I've had many GPS units (>10) and the GPS in the phone is the second worst I've ever had. Very flaky. It looks like they also tried to mask the problem by averaging a bunch of the last fixes. I say this because the speed indication trails reality by quite a bit!
And I did try the proposed settings elsewhere but it didn't seem to improve much.
Hopefully they'll get this fixed. It's not the way GPS should be working on a top tier phone.

Okay, so to change my stance a little, the GPS has been a little off tonight. Locking has been slower than I like, but it has been locking, and I saw it lock to at least 7 satellites earlier so I know it has no issue with handling that many at once.
The bigger annoyance that I'm having now is that my AGPS is off by quite a bit, telling me I'm in the next town over until it gets a full GPS signal. Not only is this annoying, but it also throws off every app that uses the cell data for coarse location, and I wouldn't be surprised if it has an effect on how fast it locks to the actual GPS satellites since it has the wrong location info to start which is the whole point of AGPS.
I actually did the GPS tweaks found in another thread, and I was navigating around my city. Maps was spot on for 98% of the time. Once or twice it put me about 30 meters away, but that was when i was surrounded by trees or concrete. Overall, I was very VERY impressed with the voice navigation, and the re-routing it did when i drove past a turn!

I'm starting to think that the processor and screen on this phone cost so much that Samsung had to cut corners in other areas to keep prices competitive. So far we've seen widespread evidence of crappy chargers (take forever to charge), GPS chips (slow and not very accurate), compasses (all over the place), internal memory (slow memory is causing the stalling issue / lag), and lack of camera flash. Hopefully not all of those are hardware issues and some can be fixed with software, but I'm just saying, they might have cut some corners to keep this thing reasonably priced. Personally, I would have rather paid $100 more to have the best phone ever made hands down. Oh Samsung.
I got it to lock like one time outside. Then I found this http://androidforums.com/samsung-captivate/128026-everyone-who-having-gps-problems.html and now it locks on inside my house. And this is actually GPS I'm talking about not wifi/cell tower triangulation. Hope it helps some of you.
I picked mine up the 19th in the burbs of Chicago. Drove up to Milwaukee with it the same day and did a side by side comparison with my Garmin GPS after my friend sent me the article.
Besides 2 minor hiccups, they worked very similar.
*the first hiccup shouldn't even be credited as a hiccup because it was an alternate route, I knew from experience it was slower but my Garmin and my Magellan of past never recognized it as the faster route.
*the second hiccup was when I was driving down 294 to merge into 94. Both had about the same instruction but out of nowhere my captivate's nav system said to take a left into a random road. It "recalculated" after a quick flicker and went back on course with my Garmin.
Recently I noticed there was an update for the Maps application which gave me "Navigation" and after installing it, I prefer my phone to my Garmin because:
1. It now gives you a picture of the destination in "street view" which you can touch and scroll around when you've arrived or pretty much arrived.
2. It shows traffic (green is good, red is bad)
3. I'm not sure if this was before the update but you can scroll through the map using the touch screen rather than just zooming in and out.
I'll do a few more runs driving between Milwaukee and the Chicago burbs before I completely set aside one or the other, but my experience has definitely met my expectations of a GPS
Why not download GPS NMEA MONITOR App and watch the data sentences. If they keep coming then it is a software problem, not the GPS Chipset. If those data sentences are stopped, then you got a hardware chipset reception problem. Try getting a clear view of the sky.
Zero GPS issues here, faster then backflip, tilt, & tilt2 for me. Grabs and maintains connection just fine.

Problems with location (GPS, cell, wifi, ...)

I've had the NS (i9023 on stock 2.3.3) for a few days now and I must say I'm generally rather impressed ... if only the GPS and other location sources didn't suck so much.
GPS (outside, on my top floor balcony):
With mobile data and wifi on it more often than not won't get a lock for tens of minutes, if at all. Even if it has a lock it'll lose it every few seconds. With both off it's actually somewhat usable - takes a while, the accuracy isn't too good (10 m does seem to be the best it can do), and the lock's rather erratic, but still, better than nothing. Makes the thing bloody useless for navigation, though.
For comparison: A Galaxy S (i9000 on stock 2.2.1) locks within 3-10 seconds, gets about a third more satellites and gives me 10-5 m accuracy. Almost no fluctuation in either accuracy or number of sats. A Desire S locks as fast if not faster and shows 8-3 m accuracy even, even though it generally shows the fewest sats.
Wifi- and/or cell-based location (indoors)
Even my trusty old i5700 (Galaxy Spica) puts me within 100-20 m of my true location even when GPS is disabled, using just cell towers, or that and wifi. Even more importantly, it gauges the accuracy correctly, that is, I'm always within the blue circle.
The Nexus S (and, to be fair, the Desire S) on the other hand puts me in a 1000-400 m circle - and I'm not even near that, it's a couple of kilometers off. What's with that?
Compass
Well, it's not strictly about location and the horse has been beaten to death but it still needs to be said: It doesn't work. At all. Instead it spins wildly, even when the phone's perfectly stationary.
On to the questions:
Is this a sw bug, a hw bug or just a defective unit?
If it is a sw bug, is there anything known about the eta of an incoming hot fix?
Are there any known workarounds?
I really hope there's a solution to this because I really like the thing generally.
+1
roughly the same here.
Same problem. We need help.

Yes .. I just don't know if I should return it over this issue or not, and I'm running out of time as today's the last opportunity.
Does anyone know if the GPS, network location and/or compass work flawlessly under CM7? That would at least tell us that a fix is possible.
yep, and i'm guessing as it's on stock it's not a software issue. it's a major issue for me as i want to dev augmented reality stuff and having the visual jump around when you're stood still is not cool.
Same thing here. Acquiring a lock can sometimes take forever. I think it's Samsung's crappy hardware, so we may all be stuck.

I am also facing the same problem with my SNS here in Bangladesh.
Peculiarly the sets gets location data using Cell tower in some areas while it doesn't in many of the areas. As for example, I dint find any problem in checking in Facebook places ot Google Place in my Work.
But have never been able to do the same same in my Home. :-S !

Is it bcz I've rooted my SNS and using CM7 ?

That's dire news ... You'd think with all the problems the SGS's GPS had and all the attention the early reviews of the NS gave to the issue someone would have spotted it - yet most were quite positive the GPS was fine.
Unfortunately reports on this and other forums are very mixed on the question if and when the NS GPS started acting up.
I guess I'll just have to send it back for now, after all I can always get another one if there's an update that fixes GPS and the rest of the location providers.
like i said in my own thread: exactly the same problems. really sucks. especially GPS and Compass are pissing me off, really doesn't work at all..
bought this new phone and expected a perfect device but got a device full of bugs, i even had a HW problem and had to give it to the support here..i thought i have a completly defective device but since others got this problems i have a little more hope.
and i really hope for a fix soon and really hope this is a SW and no HW bug.
Has anyone with a sucky GPS tried this trick (http://forum.xda-developers.com/showthread.php?t=1043034) or a similar one on the Nexus S?
I haven't had any issues with my GPS, however sometimes it may take 30sec-1min to find a solid signal. My experiences have been with stock rom and also SupeAosp 6.2 (which I'm currently using).

Nexus S GPS problem?

I bought a T-Mobile nexus s to try out at best buy before committing to dish out 600$ on the att version and noticing that my GPS is having a difficult time locking a signal. Could this be because I'm on edge signal or it shouldn't matter?
I had that captivate before and I had the same issue, does this problem also exist on the nexus s also? It's a great device but I don't think its worth it to me if the GPS isn't reliable
Sent from my Nexus S using XDA App
If the GPS is having trouble finding your location, then it's not your network's fault. It's your GPS's. Anyway, 2.3.4 should fix that, so just manual install 2.3.4 and you should be good to go.
i do note though, i have problems around areas densely populated with buildings and trees.
Not trying to be an ass, but do you even know how gps works? There's nothing to do with edge cellphone towers or anything... The phone receives signals from satellites that orbit earth and by comparing the time delay it takes to receive the signal from at least 3 different satellites it locks your location.
Now, because the signal is very weak you need to have a clear view of the sky. Buildings, trees, clouds, anything aside a blue clear sky can prevent your phone from getting a gps signal.
So every phone first use radio strength from cellphone towers to triangulate your position faster, but again it has nothing to do with 3g or edge stuff since it just compare the strength of radio signals from differents cellphone towers that have know locations.
So try out getting a gps fix in a clear day, if even in perfect conditions you don't get squat than replace the phone.

Well I was trying to use the gps on the express way with nothing but blue sits and I wasn't able to achieve a lock until half way to my destination. As much as I like the nexus s if I have to update my rom to get the gps to work then im thinking about returning it. Plus I bought the attic 4g and the gps works wonderfully!! And even though its not as open to run the latest roms I find it far smoother then the nexus s aside from the screen im really impressed with the phone.

I think the GPS lock time is decreased when you try to get it whilst moving. So if you were on express way, then that explains it. Just try to get a GPS lock in the park or standing still in an open environment. See if that helps.

You had to try hard to make that joke, eh?
There are 21 satellites up there sending signals at any giving moment, and yeah, that includes night time
Now back to topic, I don't think that you speed effect lock time since no matter how fast you are moving in your car it won't make a difference since area covered by a satellite is huge and the time stamp on those signals are in the order of 1x10^-6 seconds. And ofc a electro magnetic wave move practically at the speed of light.
There's always a visible delay when you are moving, like the position on the map is always a bit behind of where you really are, but that's because the phone only reflash your position each 2 to 4 seconds to save some battery.

Oh, ok gratti, thanks for the input. It was just a thought. So then what would be his problem ?
i'm gonna recommend you download gps status, go to the menu / tools / manage gps, and download the gps data - which is the location of the satellites. and this will help you get lock faster.
you're welcome.

Well, hard to say. Most likely it's software related. He can try download "gps status" from market and use it's tool clear and redownload gps data. That seems to work most of the times... even tho I'm not sure it actually do something or if it's more like a placebo effect. If his phone can never get a location than better replace it and be done with it.
I had gps issues with all my phones at one point or another and most of the time it resolved by itself. One day it didn't worked the next worked like a charm.
As an electrical engineer it piss me off when my phone's gps simply can't locate me even with ideal conditions. It should work. Period. But like Lewis CK says "the ****tier cellphone is a god damn miracle" sooo...... yeah

[Q] To return or not to return (GPS problems)

As you may know by now I've been having problems with GPS on my Nexus S (i9023, bought factory unlocked from Amazon Germany, carrier code EUR, running rooted stock 2.3.4 AKA GRJ22). A quick search of the Nexus S forums will tell you that I'm not the only one who complains about GPS issues - I always assumed that the GPS was just sub-par on the model and I'd have to live with it.
Only now a few helpful souls over in the accessories section said it was probably defective and I should exchange it. (I've already exchanged it once for this and the new unit I got performed exactly the same.) So I'm just going to tell you the current situation and I'm hoping you'll tell me if that's within the normal tolerances for the model: [All tests done outside in suburbia]
"Network location" (geolocation, wifi / cell triangulation) is fine since 2.3.4 [just to get that out of the way]
Time to First Fix (TtFF) is decent now, usually 15-30 s cold and < 15 s hot. I've seen much better (yes, on a phone), but that doesn't bother me.
Accuracy however, is still bad. GPS Status shows 20-10 m mostly, but it fluctuates wildly going from 5 to 30 in a heartbeat even when it's just stationary. Other phones don't show this behavior. This translates into real-world problems in Maps (checked via sat view): The blue circle goes from large to enormous and back and while my true position is somewhere within the circle most of the time, the center dot is way off. Most other implementations manage to guess the location correctly even when the accuracy is bad (as tested side-by-side).
Stability is my biggest concern. The lock'll be fine for a few minutes, especially if the phone was just rebooted, but then the GPS will lose it every few (say 5-10) seconds and take time to reacquire it. Additionally, it doesn't pick up movement very well. I did a few tests watching my position in Maps while on the tram (in a window seat) and basically it would register an (approximately correct) location every now and then but then just hang there for a while. Usually it wouldn't register that the tram had left a stop before it had arrived at the next one or even just left it again. All other phones trace the tracks almost perfectly and in real time. There goes any kind of usable navigation and - in concert with the compass issues - all augmented reality apps.
Again, this isn't meant as a complaint or even a request for a fix (though if you have one I'll gladly take it) - I'd only like to gauge if my particular phone's have been bad or if "that just how it is".
Thanks for listening.
I have a nexus s4g from sprint and my gps was working great and then one day it just stopped. I can never pick up a signal and if out does it takes about five minutes our more. I have a gps radar app that shows me signal strengths and stuff and our barely picks up give signals and they are always really weak I have to refresh the agps status all the time to even get a lock and like I said it still takes about gives minutes or more if it even locks at all. I am looking for a fix my epic had the same problems and then with the latest update for it, it was amazing and fast accurate locks. And help with the nexus s4g would be great

Get your msl, go to your dialer and dial *#*#gpsclrx#*#*, then put in msl and it will clear gps for you. It will reboot on its own

What's an msl and what does "clear gps" mean? Also, way to derail a thread ...
I tried that before on my epic and it messed up my gps but I will give it a shot

my GPS does just not work at all, it can't get a fix for hours even if there are 10 sats.
but sometimes I'm lucky (really rare) and it gets a fix but the longest time it hold it was 5minutes, then lose GPS fix can't get one again. it's even not while i'm moving, phone lays on the table and outside to test.
really disappointing for me, second thing is my compass does not work after reboot and is really inaccurate and unstable (jumping around)

Your GPS sounds even worse than that on my NSs, the compass doesn't work for anyone. Out of curiosity - where did you get yours?

i'd like to ask if this code is good for Nexus gsm or cdma??

According to the article you linked: "This program reads your Master Subsidy Lock (MSL) code for your CDMA Android phone."
In other news, I'd really appreciate some on-topic replys

I even think my GPS is the worst of all the Nexus S.
Mine was bought from Ebay-UK and since it was on a repairing-tour to samsung germany i know its from CPW. Its a I9020 not I9023. BTW there was nothing repaired because they said "The discribed issue cannot be found" or something like that..
what do you mean with compass does not work for anyone?? does it really not work on any nexus? thats interesting, isn't it a little bit illegal to sell a device and say it has compass and than compass does not work at all?

mh sounds like this will not work for GSM-Nexus
the GPS on my NS behaves similar (but better) to what you describe in the first post but overall it seems to have better accuracy and stability.
Have you tried recording a track while in a car? The results should be better. At least with mine it's mostly accurate and rarely looses signal (unless you go under a bridge/tunnel)

Hello,
I have the same phone, NS4G from Sprint, and the same symptoms. The GPS worked fine for a week or so, and now I'm lucky to get it to work at all. Sometimes I can get a lock after 5+ minutes (while not moving), but other times it never occurs.
I just tried resetting the GPS as is described in the post above. It says "it will reboot automatically" - does that mean the phone or the radio?
In any case I just pulled my device battery after GPS reset - I'll post back with results in a few minutes. In the meantime can you explain what you did after following the reset with dialpad/MSL?
Also attempted return...had to send in for repair
I also got a bad GPS Nexus S i9020 from Amazon.com USA site. The GPS would not lock without a wifi signal. I eventually caved in trying to get it working with rom flashes, drove me nutz, but tried to return for cash and missed the date. Had to send in to Samsung then and get the repair. I have been somewhat satisfied, having gone from no GPS to finally getting it to lock, but its a poor excuse for a gps chipset. The SiRFSTAR from my old WinMo days kicks this gps in the arse.
I also get the bouncing sensitivity and wandering location circle, but accuracy hovers around 5-10m now, but the location is never fixed solid, its wobbly, even outside with clear skies above. The compass is another huge weak spot. Samsung dropped the ball on this device, I wish I could return mine and grab an HTC unit. Google should learn from this and drop them for the Nexus Prime. I think this is unacceptable as location services are whats hot now and this device fails as a flagship product.
I like the gps on my sgs2 more (it has a sirfstar IV) but, i have to say, it's not that much better.
What i gained in stability i lost in TTL. Sometimes you need one more than the other.
The SGS2 has taken me up to 10 minutes to get a lock and if conditions aren't good (cloudy sky, tall buildings) it can easily take 5 minutes. Sometimes you just want to get some signal to get you going.
I did a trip of more than 2000 miles with my Nexus S, using the GPS most of the time, and it worked ok enough for navigation for most of the time. The only times it failed me were, as i mentioned earlier, in old parts of cities with narrow streets.
You are right when you mention HTC, because usually their devices have better working GPS.
Overall i wouldn't say it's a bad device, you have to keep in mind this is not a dedicated GPS device, it's a smartphone that does a lot of things, some better than others, it's still a good developer phone, which i think was the main goal of the Nexus.
After upgrading to the SGS2, the main differences i noticed were not the GPS but the speed and extra memory! The Nexus S is not slow and has average memory (512mb but with only around 380 free) but if you have a lot of apps running (and it's easy for this to happen) it will get sluggish and begin to close the launcher when you start a heavier app. I found this had a lot more impact on usability than the GPS weakness.
