I must say this is the kind of stuff I like to hear! If it works in a train it should work in a car.

I just took the plunge and ordered mine from Clove. I should have a few days to take it for a spin before my 30 days runs out on my Atrix, so I can see which one I really prefer.

oooh krap! Haven't tested GPS yet :O

I'll give you all a detailed reply once I have sometime.

Meanwhile can you recommend me an app to do this with? Like a gps journey recording app. Preferbly free. Already have a TomTom for car.

i.e basically using the app and after taking screenshots of everything and posting them here instead of me having to write it all out. :)

Of course you're right but I think most people here realize all of this and it's just part of being in a forum. We are people that love our phones. Most of us, while we may love empirical data, are not here because our livelihood depends on whether our phone is accurate to 5m or 10m.

Absolutely excellent post - exactly what we need to weed out the misinformed or emotional "opinions" and just get to the cold hard, gps located facts. It's science, after all. If you agree - I'll add the metrics to the first post?

Don't forget to include the fact that car navs have tendencies to approximate your location based on the road. (example: drive through a newly constructed road that has replaced an existing section that only exists in the map or times you drive through the tunnel where gps signal can't be found)
[Galaxy S II Q&A, Help & Troubleshooting] :
what's the point of this thread?

I believe the op already returned his GS2. So, why is this thread still going?

It's just another phone, if you are convinced that the GPS is not not working, get a HTC or a iphone. If you think it's working, then all's well. This thread is starting to look totally irrelevant to me. Few guys saying it's working, some saying it's not working. It's obvious nobody is going to concede defeat. And weirdest thing is that it should not matter to the op as he does not have the phone.

I need this thread ... for me a crappy GPS is a absolutely NO-GO :(

For many years I have been using my Touch HD as GPS in my car, and it have never let me down, no lag and high precision (1-5 meters depending).

alsheron - something else to consider adding, wifi on/off, "use wireless networks" on/off, and if the S2 has the "use sensor aiding" setting whether that's on/off. Lastly, firmware release could be helpful.

I need this thread and I think this one is one of the most important thread for Samsung device because of their bad GPS reputation for previous devices.

This thread is useful to a lot more people than the op, most notably all prospective buyers. One could even argue that it is irrelevant to people who do have the phone, since they're most likely stuck with it either way. No use crying over spilt milk and all that ...

Secondly, its whole point is that the quality of a GPS implementation isn't a matter of conviction or belief but something that can be studied with a reasonable degree of objectiveness.
[Galaxy S II Q&A, Help & Troubleshooting] DJGibbon:
In fairness, that's a quote from me, and I'm very much not the type of person to defend the indefensible - I was using it in the context of hoping that the problems were fixed, not that I would ignore evidence either way ;)

Anyway . . .

Here are a pair of tracks which I made this morning. One from the SGS2, one from my HTC Desire. Unfortunately I didn't see the requests for further data, so I didn't get TtFF or anything - might be able to try them at a static location this afternoon.

Both phones side by side on passenger seat of car

Neither phone powered externally

Wifi off

"Use wireless networks" off on both

"USe sensor aiding" off on SGS2

Desire track

SGS2 Track

You should be able to open both, then click on the "traffic" dropdown in the top right to view both overlayed for better comparisons.

It's mostly motorway, unfortunately not a lot of heavily built-up areas - the most built up is at the end of the journey (East side of the map). The loop at the end, by the way, is me pulling into a car park that isn't visible on the map ;) I started the phones at a junction some way away from my house - didn't particularly want to advertise my location!

Overall, I'm fairly happy with the SGS2. There are places where both deviate, but I couldn't say that the SGS2 is significantly worse - look at where I come off at J10 of the M6, where the Desire takes a big swing out to the right while I'm travelling very slowly on a straight bit of road.

One thing I certainly noticed is that while walking out to the car and getting the GPS fixes, the SGS2 fixed quicker, but the Desire seemed to have a more accurate "blue circle" - in MyTracks, at the same zoom level, the circle for the Desire was a dot in the middle of the arrow, where on the SGS2 it noticeably extended around the arrow. Whether this is a true reflection of the fix or whether there is some misreporting going on is well out of my expertise to guess.

How useful this will be for people is up for debate. As fallenguru says, different people have different needs from their GPS systems - all I can show here is that in one set of conditions, my particular SGS2 performed no worse than another arbitrary phone.

Bear in mind that GOOGLE MAPS IS NOT PERFECT. Comparing the satellite and road images will show this quite clearly - there's often deviation between the two. The *really* important thing to realise is that *neither* is necessarily correct - if the gmaps road cuts a corner that isn't on the satellite imagery, then the gmaps road is clearly wrong, but in a situation where they're offset by a few metres, either could be the one in error. This is the nature of map stitching and is essentially unavoidable.

Apologies for wall of text ;)

Hallo from Hellas.

This is my first post in the XDA forum's.

Just yesterday I receive my new SG II.

I have also the SGalaxy 9000.

For the GPS the first time inside my home I have 10 satellites and the error is 22 meters.

Outside of my home I have 12 satellites min. and the error is 6 meters.

This is with GPS status app.

I tried to walk as close to the water as I could (the initial bit is wonky, but I was actually walking like that to avoid obstacles, roadworks etc). You can really see how accurate it is when I start to walk left along the water.
[Galaxy S II Q&A, Help & Troubleshooting] Shocky2:
Picked up my Galaxy S2 today, the GPS sucks worse than the first one.

Think I got 4 locks outside, completely useless.
[Galaxy S II Q&A, Help & Troubleshooting] samnada:
I assume "the first one"=SGS1, and "4 locks" was 4 sats locked.

Did you have wifi on? Were you near any tall buildings or under thick trees? How long did you wait?

Does sound discouraging. Reports like this make me think there may be a significant HW QA problem with about 20-30 percent being sub-par. We know some of the SGS had a HW issue. If the S2 also does another reason for US buyers right now to hesitate due to warranty support issues.

Thanks.

[Galaxy S II Q&A, Help & Troubleshooting] jonrwg:
Thanks. Gonna try after charging mine. Before this I use GPS test (I think), and mine shows 11, use 10. Forgot what is the rest but when using google map it quite accurate (blue circle). And something on the blue circle "500meter accuracy". Is this a good thing? Going to try again tomorrow side by side with my DHD.
[Galaxy S II Q&A, Help & Troubleshooting] samnada:
GPS Test does show accuracy in the upper right. I've never seen an accuracy reading in Google Maps, but 500m accuracy is extremely bad.
[Galaxy S II Q&A, Help & Troubleshooting] jonrwg:
Will try again tomorrow. Charging it right now. But when I zoom in google map it does show my location accurately, just 1house apart because I test it indoor. Oh well, going to do lot of test tomorrow. :)
[Galaxy S II Q&A, Help & Troubleshooting] fallenguru:
Nice, but ... Where did you test? What settings? How long did you have to wait? Were the 4 m stable after a certain point or did they fluctuate a lot? How about the locked sats? Which firmware?

Let's put it this way ... in Maps I usually have 40 m accuracy even with GPS turned off, i. e. using only cell and/or wifi positiononing, and that's spot-on.

You probably didn't have a GPS lock at all.
[Galaxy S II Q&A, Help & Troubleshooting] jonrwg:
Did 2 test indoor. Is it good? I'm new into GPS stuff. :D
[Galaxy S II Q&A, Help & Troubleshooting] sogo87:
20m error isn't bad for indoor but you should try it outdoor. After all you are going to use it outdoor where the signal will be better and the accuracy will be better. A good GPS will give you a 4-6 meters error outdoor.
[Galaxy S II Q&A, Help & Troubleshooting] Intratech:
I was outside near a bus stop on Brighton Road, the postcode there is CR8 2PG. I waited all of maybe 20 seconds for it to get to 4m and as for stability it fluctuated between 4m to 5m occasionally and maintained a lock on 10 to 11 sats. I'm using the XWKDD firmware, no root or changed kernel.
[Galaxy S II Q&A, Help & Troubleshooting] alsheron:
Now that's GPS performance no-one can be unhappy with - well - not for standard, everyday civilian use. I wish my SGSII had GPS performance like that - if it had, I'd probably still have it. VERY interesting that you're on the newest firmware - didn't even check mine but as I got it on the day of release it was probably an earlier version. Maybe the firmware has something to do with this?

Great Stuff.
[Galaxy S II Q&A, Help & Troubleshooting] ickyboo:
Did the OP use the GPS in a CLEAR SKY? GPS ain't sposed to work in buildings and barely even works with clouds
[Galaxy S II Q&A, Help & Troubleshooting] Shocky2:
Yep, you assume correctly, I tried with wifi on and off and waited a few minutes, 4 locks was the best it could get outside, inside I barely got 1 lock, 4 isnt even enough for a location.

Pathetic considering my mates legend gets 10 locks indoors in 5 seconds. :(
[Galaxy S II Q&A, Help & Troubleshooting] SBS_:
Sounds like something is wrong with your phone. I get 7-8 satelites locked inside and outside I get 10-12 locked..

I must say though I had some issues with the gps lagging today and jumping and stuttering all over the place, but after I restarted the navigation program I was using (sygic aura) it became like butter and showed my exact position all the time and updated quickly.
[Galaxy S II Q&A, Help & Troubleshooting] guest member:
Someone linked to this thread from another forum. This prompted me to go out for a nice drive to test the tracking. It also prompted me to register here to post it, although I've lurked here many a time.

Anyway, here are my tracking results:

I hope I don't get in trouble for this, but there is an anti spam rule that says I can't post an external link unless I've posted 8 posts - but I think this information might come in handy so to bypass that, and to avoid spamming the board with 7 more messages, I've put a space after http: in the URL below. Just copy and paste it the URL, taking out the space.

http: //maps.google.com.au/maps/ms?hl=en&ie=UTF8&t=h&msa=0&msid=205550739366247842723.0004a2aec86b693a0664e&ll=-34.079998,150.793962&spn=0.007491,0.013937&z=17

Please read the notes on the map for some detailed information on certain parts of the track. Only at one short stretch of road was the position off more than three metres or four metres. The phone was in the passenger seat and the area I traversed can best be classed as low density urban sprawl in one of Sydney's south-eastern suburbs. I had WiFi turned off, I had a full tank of gas, half a pack of cigarettes, it was dark and I was wearing sunglasses.

I think there might be a problem with some phones, or some batches, but mine works flawlessly the three times I've tested it.
[Galaxy S II Q&A, Help & Troubleshooting] samnada:
Those accuracy readings aren't very good. It would be nice to see the same screenshots taken outside in a clear area. If you could also provide time to lock, time to best accuracy reading, amount of fluctuation in accuracy, and firmware revision, it would be most appreciated.

[Galaxy S II Q&A, Help & Troubleshooting] samnada:
Sounds like a HW problem unless you were surrounded by tall buildings when outside. Even then the comparison with another phone inside is quite significant. If I were you I'd get a replacement.

The variation being reported for the S2 isn't comforting. The poll is still running at least 20% not achieving <10m stable accuracy. At the very least it indicates the importance having access to warranty service.
[Galaxy S II Q&A, Help & Troubleshooting] Shocky2:
Yeah just like there was something wrong with my SGS, I've never seen a SGS with working GPS and know allot of people that have them, so doubt I'm ever going to see a working GPS on a SGS2 to be honest.

I'll contact Samsung and see what they have to say about the issue again, I don't really use the GPS anyway, just something to play around with now and again.

[Galaxy S II Q&A, Help & Troubleshooting] andrej.marinic:
hi there. i'd like to share my (hopefully unbiased) opinion regarding the sgs2 gps. up until a few days ago, i was using my sgs as an every day phone. the first few months were a total joke when it came to using the gps. i ranted all over the place about it (feel free to search the forum), even joined a group on fb, hoping it would bring some more attention to that little fiasco. however, in the last few months, it has greatly improved as has almost everything else about the phone (overall stability, speed).

i bought the sgs2 because i'm very irrational when it comes to spending money, but i do not regret it. mainly because of the gps to be honest. while the sgs improved, it is still light years away from what the sgs2 is capable of.

i travel on weekdays between south ealing and reading and have been testing the device every day. the gps is perfect. i've tested using the weird holder in the passat (the one which opens on push) and also placing the phone on the seat next to me. worked wonderfully each and every time.

having said that: while in the city, with all the high buildings around me, the gps does not perform well. but i cannot expect it to either, so that is ok. if the phone does not have a visibility to at least 4 satellites, how can i expect it to work?

so my verdict is that the gps indeed does work and does so quite well.

Hi all,

I found out that when I use kyrillos ROM 4.1 OC edition on my samsung galaxy apollo i-5800 then the phone sometimes freezes with only a reboot possible.

It occured to me this happened only in idle (no cpu intensive actions) mode.

With setcpu I raised the lower frequency limit from 83 to 166 Mhz (also in screen-off profile), because I thought the freezing could be related with lower 83 Mhz.

Since then I "never" ran into freezes anymore with my phone...no issues when cpu is between 166 and 1300 mhz (yes no issues even at high clock speed, against all laws :-)).

I just wanted to share this information for other people having the freezing issue, maybe also on other customized ROMS, just try this min cpu setting if it works for you :)

BTW I didnt really notice worse battery life with this 'remedy'

Enjoy your phone, it's made for you !!! :D

i5800 freeze

I'm new on this forum, but I'm used to flash my phone.

I got the next problem, I'm running Kyrillos'rom 9.7.1 (update) for 2 weeks.

On my first install of kyrillos my phone freezes when I was 2 minutes working, so I installed setcpu to lower the cpu-speed and It worked.

Now, I had to flash my phone again, because I did something wrong in the system file.

I re-installed the kyrillos 9.7.1 update with Odin, but then, when my phone boots, it almost immediately freezes when I do something.

I don't get the time to install setcpu to lower the freqency :(

I tried it almost 20 times...

Can anyone help me lowering the frequency?

Thanks!

UPDATE:

It worked, I finaly got into my files to install set cpu! After 30 times rebooting...

But My question is still there, because It's almost impossible for me to flash my phone again now!
