Slow and inaccurate GPS in india? - Galaxy S II Q&A, Help & Troubleshooting

Hello
Is it only me or I'm having issues with GPS takes a lot of time to fix and also the position is far beyond invalid
It used to be so good with my x10(the only thing I feel it lags on my s2) I'm a traveller and I find Google maps much useful and I'm lost without it. Can anyone help?
Also I've tried changing ndp using fasterfix from the market. Any help would be appreciated

More info: Is it stock rom or custom rom, which modem, have you ever changed radios.
Are you on the rom for your region?

Its cognition plus speedmod I never changed radio

Am using sgs2 in delhi..n i have absolutely no complaints..gps is smooth as butter and took me to weirdest of places in those galis near nizammudin station too.
And also FYI my s2 takes about 3-5 seconds to catch a gps signal while first starting the map application.

Nope, I'm in Bangalore and GPS is working perfectly. Super fast lock on (usually less than 10 seconds), solid stability, all well.

Same here. I'm in Delhi and the GPS is working perfectly fine....locks in less than 5 seconds.
BTW, i'm on LeoMar 2.7.1 rom, moden KI3, Siyah's 1.7.7 kernel.

I am on stock rom and experiencing same issue never happened on my x 10

When you bought the phone and got it home did you take the phone outside and wave to the man in the satellite to let him know you should be on his connection list .

Well problem for me too..takes around 5 to 7 mins to get a lock...once it does its fine though...m on stock ke8...should rooting or updating software improve this?

Check your A-GPS server. I had very poor performance using the normal A-GPS location servers but then changed it to xtra1.gpsonextra.net using FasterFix and now it locks much much quicker and the accuracy has improved (my location is no longer 20 meters away from where I actually am).

Hi,
I am KI3 and lives in chennai...
i have no issues with GPS...its gets a better accuracy like 3-4 mtrs outside my apartment.....inside my home, its kind of Ok, but i will live with it...why i need gps inside my home
and i always use directions>maps whenever i want to goto some place and till now my SGS2 baby it never let me down....she will come and direct me whereever i want to go....
may be try flashing KI3.....

Gps works awesome for me in delhi.no issues at all

[Q] Constant switching between 3g/h/h+

I have looked around and found other threads discussing changing between 3g/4g however mine seems to be far more quicker and unreliable than it should be, I have had this problem on kg3/kg6 but dont remember older modems.
Anyway I will be on my phone and within a minute time it will switch 10+ times between all three networks. Im also getting very unstable network connection and the network is slow which it should be a lot faster.
Is this a modem issue or kernel?
I noticed this as well since picking it up yesterday. At first i thought it was doing this when it was sending and receiving data but that isnt always the case.
Im on Cognition 1.31 with KG3 but also saw it on stock KG6

Yep, same issue here. My data is very unreliable and slow as hell at times. Just got the unit yesterday and it's already annoying the hell out of me.
When it works, it flies. Unfortunately, the radio of my Chilean SGSII seems to be unable to maintain a solid working connection under various signal conditions.
This is pissing me off and making me want to return this to Amazon. FWIW, I had similar data connectivity issues with an unlocked Nexus S (i9020A). Mostly slow data (like 300kbs on 3G slow). I tried three units and gave up. Is this a Samsung issue?
Would flashing/rooting/installing a custom ROM fix this? If not, it's back to my Atrix.
I may have just solved this by disabling fast dormancy (*#9900# in the dialer) so far it will switch but more when I'm not using the internet. And speeds have shot up! Does this work for everyone else?

The fast dormancy trick really didn't do anything for me, unfortunately.

How is the GPS working on the Samsung Galaxy S 2?

I'm sure everyone knows about the GPS bugs that plague the first generation Galaxy S. I've read the SGS 2 reviews and they said the GPS issues have been fixed, but can I get some opinions on whether anyone experienced any GPS issues? Is the GPS on the SGS 2 as accurate and good as the one on the iPhone 4?
Works fine. Faster lock than my IP4.
Its much faster than the Galaxy S1. I found the GPS to be close to useless on S1. On my S2 its close to perfect
Sent from my GT-I9100 using XDA App
Works great and picks up signals inside buildings.
I had the sgs1 for about 6 months and now the sgs2 for about 3 weeks. I was soooo disappointed with the first sgs and like you I was unsure if I wanted to give the 2 a try...
Well I read a bunch and it seems that most people are happy so I bought it...
I can say with out a doubt that the GPS is way better on the 2 than the sgs1. I could not use Google navigation at all with the sgs1... it was useless and could never lock on and would have me blocks away from where I was. I've used my sgs2 GPS with Google navigation on more than a dozen trips /drives and it has always been spot on and never had me in the wrong location.
I will say that lock times are very slow when Im driving

I run every other day for an hour or two, I use runkeeper, also when out hiking I use mmtracker to read my o's maps, I can safely say especially with runkeeper the gpx routes recorded through the SGS2 are far more accurate than the iphone4 even managing to stay accurate whilst running through the forest, actual initial cold starting is about the same if not slightly faster with the sgs2. Oh yes and practically every time I recorded a run with the iphone4 through a certain part of my forest run it would create a spike where I was apparently running at 250mph hmm not sure I am that fast, but the sgs2 always keeps an accurate smooth record, hope that helps
for me, flaky. some days i'll get a lock within a minute and then it's fine. this morn and yest - takes ages to get a lock.
basically, ymmv
Download FasterFix. You can choose from a list of servers. Choose the country closest to you or, if it is in the list, your own country. This way you'll 'half your fixtime' so it connects faster to GPS-Sat.
It's like using the aiding sensors (e.g. WiFi).
I get a fix in >10sec max.
Hope it helps.

i think gps on SG2 is far from perfect. It's "OK" but i had much better gps on my previous phone (HTC Hero)
What is the average time for a fix, for you guys?
Sent from my GT-I9100 using XDA App
Mine takes between 10 seconds and a minute. Sometimes it just sits there doing nowt lol.
Xperia X10 used to lock in 10 seconds every time, but the rest of that phone was slow lol
The only time I have ever had a problem getting a fix, I simply opened up google maps and it seemed to get a fix instantly then returned to my other gps application and all was ok.
First thing in the morning outside fix within a few seconds
Indoors sometimes can take a little longer, but never more than about 10 seconds
I use GPS a lot

I guess you said this to clarify that you've got good statistics, but a very interesting thing is that if you use the GPS often you likely get shorter fix time
The reason is that if you used the GPS recently (within hours) the cached GPS info is more accurate so the GPS doesn't need complete messsages to determine the position (it takes 30 seconds to send one complete position message from a satellite), and if you get interruptions you need to wait even longer, that is why it sometimes takes more than a minute to get a fix.
A-GPS also helps fix time in many cases.

Same thing happened to me.
Absolutely brilliant.
90% of the time it gets a lock within 30 secs , there's been sometimes when it needed a restart to get gps working properly but that's down to an app I was using previously which messed things up a bit, but on the whole I very happy with it.
The seamless integration with google maps is great. The external speaker is plenty loud & clear enough to hear the instructions but would like a less robotic sounding voice, re routing is quick & so far its been 100% reliable.
I have a built in gps system on my Land Rover but I almost always use the SGS2 gps over it. I used to have the SGS1 but the gps on that was a piece of crap. Gps on HTCs, etc, are probably just as good/better/worse, I don't know but one thing I'm sure about is the speaker volume would never be as loud & clear as the SGS2.
I get a lock up to 4m accuracy. My Captivate always had about 1500m accuracy and couldn't use it. Using navigation works perfectly on my sgs2

Excellent
Like others here, i suffered from the original SGS gps nightmare
SGS2 gps has been great for me, able to use google maps/navigation/RAC app all without problem
I didn't realise how much location based services I used untill the problems with SGS gps clearly highlighted this. Now, with my SGS2 all is good.
Is there an app like the LBStesmode for froyo that I can use to change/check the gps settings?

[Q] Running Hot - Any suggestions?

My first time posting here, so please be gentle.
I've had my SGS2 for around 6 months now, its an unlocked ASIA (as I live in BKK). I noticed on the original stock firmware that the phone was running hot, as in the back panel around the camera would heat up to the point I could feel it in my pocket. This would normally happen if I was using a game like angry birds, or a psx emulator. But sometimes it would happen in the browser under normal conditions. I just thought this may be a issue with dual core phones, so I took this as a 'feature' and accepted it.
But now lots of people I work with have this phone, and it came up in conversation about heat. Everyone stated they do not have this issue, that the phone remains cool all the time.
I have moved between many different ROMs, and have finally stuck with Westcrips ICS ROM. Then a strange thing happened, the heat issue goes away with version 8.4. Phone is cool all the time, even playing my PSX emulator in software mode. Battery also increased from 12 hours to 16-18 hours.
But now I just moved up to 9.3, and its back again, the front screen is very hot to touch when using things like the MX video player, or surfin the web. And if I launch a game ... well, forget about it. The battery drain is immense to, be lucky if I pull an hour of use like that.
Anyone else suffer from this? Hardware fault? I can't take it back because my flash counter is probably in the 20's now, and I can't find a reset JIG in Bangkok.
Cheers.
FYI, I always do a clean wipe, dalvik / cache / permissions.
same issued here, phone bought from Thailand also. Phone getting hot when browser,downloading and playing some games( not all). And its really hot
Changing Rom and kernel sometimes solved it for awhile but eventually will come back.
Looking for solution also
Thanks
P/s: right now im using LA4 stock Rom and CF root LA4 kernel and still get hot

Thanks for getting back to me.
The one I know that fixes it is Resurrection 8.4. Its a dam good rom, and given me the best battery life (once I got 20 hours with normal use). But there is an issue with touch screen sensitivity that makes it annoying.
Maybe its something to do with the Kernel on the Asian models?
If I find a fix I'll pm you.
Hmmm mine only gets uncomfortably hot when playing some 3d games. Didn't experience the same level of heat when just browsing though... It just gets a little warm but far from gaming temps.
What i did was undervolt and underclock when playing. It did reduce the heat and extend the battery though i admit it's not the best solution / workaround.

What settings did u use for setcpu if u don't mind me asking? Will it work on ICS?
Sent from my GT-I9100 using XDA App
I use Tegrak Overclock so I can mess with clocks and voltages with the stock kernel. See below for my settings... 100% stable on my phone.

Cheers mate, will give that a go when I get home.
Right now my phone is warm all the time, just lost 20% battery as well in 1 hour.
Sent from my GT-I9100 using XDA App
Well it looks like the ICS kernel is not supported right now under Tegrak. It is bleeding edge.
I tried setCPU to under clock but ended up with a lot of slow down and some full system freezes.
Guess its back to 8.4 until I find a more definitive answer.

Since you're using Westcrip's Resurrection Remix, you can get rid of the triangle by using Chainfire's TriangleAway app - I'm using Resurrection too and it got rid of the flash counter and the triangle.
TriangleAway should work on all ICS roms though.
Strange, installed triangle away yesterday evening. Work like a charm, so I guess if I need to return I can now.

Thats not normal, it happened to me with my previous SGS2. Changed in warranty by my carrier.

I guess that's my only option. On a new from and its cool now, but reset my counter for the flash so can get a service now.
Sent from my GT-I9100 using XDA App
i have resolved my problem by flashing a custom rom.
which from did you flash?
I'm using Thebyani ics v3 and after I disabled the stock browser all is good. Battery life too.

[Q] GPS in Longhorn 2.9.3 tells me I'm swimming by Africa

Hi all.
I updated my Olleh 2.3.3 to Longhorn 2.9.3 Updated 9-5-12 yesterday.
I have few problems now. One of the major ones is GPS showing wrong location. Basically when it can't get a proper fix it fixes itself with 0.000 x 0.000 witch of course is by Africa ant stays there (I'm from UK). Olleh 2.3.3 at least was telling me that it can not get proper fix or was staying at last known position which was much more convenient.
Do you have any answer for that?
Cheers.
Hi there I use an app called fasterfix its free from market it sorted out for me

I tried Faster GPS, Faster Fix, GPS Status. None of them works.
Don't get me wrong. Outside GPS works great. It gets fix quickly and stays fixed. It just when I'm in the building instead of using last known position it takes me straight to Africa.

if you dont realize it yet.. gps is never meant to be inside building... dont blame the gps if it sends you to africa...
by the way.. longhorn 2.9.3 gps module usually takes time before it corrects itself out.. usually approx 30 ~ 120 seconds...
the first few seconds always a null fix...
Make sure that the internal GPS is selected from the Location menu under settings.
I installed DSC Phoenix kernel yesterday and it fixed my problem. No more trips to Africa. When it can not get a fix it simply tells that it can not, instead of fixing at 0.0000 x 0.0000. It's important when you use apps like "Friday" which counts the amount of miles you moved during the day. Imagine the statistics.Tens of thousands of miles daily

Ms team gps problem

Hi all, Im having a huge problem using the gps on my Phone.
I gets the signal from the gps if I don't move. When ever I start go drive faster then 30 km/h it looses the signal and usually never return. I tryed to clear my Google Maps cache, but it works only for a short part of time.
Ive install the gps fix, but it didnt helped a bit.
Im using now the newest rom (7.1 I belive)
I didn't get these problems so ofthen when being on 7.0.

My device just got alive, On the way to Warsaw the gps just by it self started to work, and to get the most fun, it didn't loose the signal even on one sec.. in the 1 km tunnel on the start in my home town(Where I previously couldn't get a signal for few seconds)...
I can understand very bad weather, but today there has been all day the same weather conditions(getting slightly worst in the end)....
Can someone tell me that is the problem ?
GPS is a very important utility in my phone, as I'm always using it where ever I am.
