Help GPS issues?

phaedrus said:
Hi Beards,

I presume Froyo is definitely going to include the GPS and file system fixes? Is that confirmed?

It seems that, from the noises made by people who downloaded the most recent 'leaked' versions this week, there's no unanimous agreement about massive improvements in either of those areas :(

thanks

The reason it was pulled was because of the filesystem and not getting it to work correctly.
However, what's filtering though is it's running smooth and any errors that crop up can be dealt with either 'in-house' for a later small fix or by outsiders like xda-devs.
 
I took the bait and I'm currently running JPM.

Here's a link to a GPS track, recorded this morning, about 9 miles in the car.

http://maps.google.co.uk/maps/ms?hl=en&ie=UTF8&t=h&msa=0&msid=101430992004295645691.000492a40dc41bd34aaae&z=13

Not perfect, but not too far off!

No idea whether JPM will be the release version of 2.2, or if it includes the GPS fix. I kind of hope the GPS fix is separate, as there's still room for improvement in the track above!

On another note, the overall graphics performance of JPM is poor. Even with the popular OCLF, the quadrant scores are way down on JM9 (JPM=1750, JM9=2300)

I know, I know .. there's a whole raft of arguments about the benchmark scores, but there is noticeable lag in JPM, even with a lagfix installed.

You're saying that Samsung are actually willing to rely on XDA to provide fixes to people for their software issues.

*sigh*
 
It still has you driving through some 50 backyards instead of on the road for a good part of the trip though. I've seen lots worse but its still not really great. It looks about similar to what my unit does. Were there any complete losses of fixed position or just inaccurate? I can see atleast one spot that looks like a lost sat fix.

No... Not in the slightest but they can not deny what does not get sorted within 'their time scale' most likely ends up on xda-devs doors..... if you follow my drift.

Anyway, I'm pushing for further info at the moment........
 
Okay, it's rolling out in the Scandinavia countries at the mo....

EDITED:
Any users in Germany, check Kies now.

Hmm, I hadn't really checked it that closely to be fair :-)

The more I do look at it the further from perfect it gets!

did you flash the leaked version using odin or tricked KIES to pull the update?

I was using Odin until this morning, and since then I've altered the registry and just updated via Kies.

It gave me JPM and JP6 (one for the phone, one for the pda, can't remember which way round), whereas until today it was all JPM.

May be all in my mind, but this update via Kies certainly *feels* snappier. Maybe it was the JP6/JPM mix compared to all JPM!! I dunno.

I also now see all of my purchased apps in the market, whereas I only did with JM* previously, not JP*
 
Guys, let's face it: Samsung will not be able to fix the GPS issue. Actually JP6 gps performance is about the same as before the upgrade. This is a test drive I've done in the city jungle this night. Blue track was recordied by SGS, purple was recorded by a Wayteq N800 unit in the same car (actually in a less optimal position than the Galaxy)

For the second round I've switched LBS mode from standalone to MS based in LBSTestmode and repeated the same track. The colors are the same.

I am totally hopeless. I will try to sell it and will never ever buy anything produced by this utterly incompetent company again.

That is really strange... I have seen some track data and it is totally spot on.
Quick question... Where did you pull the update from and did you factory reset afterwards?

Performed a factory format (*2767*3855#) before the upgrade and pulled the upgrade by fooling kies to think it's a swedish mobile - changing HIDSWVER to I9000XXJF3/I9000SWC/I9000XXJF3/I9000XXJF3 and ProductCode to GT-I9000HKDXEE - (from GT-I9000HKDXEH) in the registry.
I do not know other paths you've seen why showed better results, possibly because none of them recorde in a city jungle. GPS performance cannot be tested on mostly open areas, even my girfriend would be able to design a GPS receiver which works with that conditions. Difference between a good GPS design an a piece of shoot can be seen when signal reflection kicks in and/ord sky view gets blocked for some degree. Yes it's tricky to give fairly accurate results while receiving mostly multipath signals, but the proof it can be done is the recorded path of the other unit utilizing a SIRFIII+ receiver in the AtlasIV CPU.
Samsung's unit literally NEVER was able to guess my position within the reported accuracy circle yesterday. It's not just inaccurate, but lying about it's accuracy too.

Yes compi, I'm all to familiar in how to get the best and what tests to carry out.... have been involved heavy in the xda-devs GPS topic .

My material came direct from Samsung where part of the tests were to not just use Google Maps or Navigational Applications which 'pulled' the signal on a designated road but use apps such as My Tracks.
The results were very good ranging from urban to sub-urban districts both walking and driving.

It will be interesting to see how others get on, just so long as they do the tests thoroughly.
 
After getting those results with froyo release (JP6) last night, I fooled kies again to be able to re-flash the current official firmware for my country (JM2) (then i fighted few hours with the product code which seemed to remain intact (XEH) while flashed Scandinavian froyo, but magically changed to XEE when kies flashed back Eclair) Then I updated the same fixes (JM6 GPS files first, then vibrant JI5 GPS files) I applied before.

This is the first test using MS based mode
then the second using standalone

As usual there is a reference tracking recorded by an AtlasIV based unit in the same car.

For me the the JM2+JM6+JI5+standalone combo seems to be the best (or least worse) I'm just preparing to repeat these tacks using official JM2 without any GPS "fixes" applied

was shocked to learn that froyo did not fix the GPS....
how abt wifi issues and lags on froyo...
any experiences would be great.

Can't blame you, its quite frustrating. And returning the phone to the retailer is probably going to be difficult in most cases, since the GPS isn't entirely 'broken' it just is so unreliable that it becomes pretty much useless. But a lot of retailers will probably refuse returns saying 'see, it works, it gets an accurate fix within half a minute'. That you can't drive 10 miles without losing the GPS signal/fix a bunch of times isn't really gonna help there I'm afraid.

I hope you get a good price for it, though I expect there will be a lot of almost-new SGS's being offered for sale once people realize this update isn't gonna fix the GPS problem.

Mine may be one of them, or maybe ill just buy a standalone GPS unit instead. Either way, good way to lose customers, Samsung.. Whats worst of all imho is that they continued to sell and produce(!) more faulty devices despite being aware of the problem, while giving the false impression that the issue will be fixed. That may be grounds for a class action lawsuit.

Nope, it will include neither.

I missed phaedrus's post so did not reply (sorry phaedrus).

Anyway, Shocky, what information are you basing this on!
I have not seen anything official stating the official update will not include the fixes.
Granted there are a number of members and other users reporting it has not rectified their phone's but I've not seen anything in concrete stating the fix is not working.

Think about it... Samsung are fully aware they had to get this right, hence why it's taken so long. For them to push out the update and not achieve would be meltdown across the web.

Sorry, it'll be through Kies I'm afraid.
Incremental updates can come OTA but this kind of update will require to get right at the heart of the filesystem.

Actually nearly all android updates, and even the previous 2.2 updates were/are OTA, only Samsung is hanging onto their relic KIES software for a tethered update, probably so they don't have to write a seperate dissolving installer (another thing to mess up).
Hopefully though they are performing some sort of voodoo to fix the bit of I/0 lag, and maybe that's why they think KIES is relevant/necessary. The problem with KIES (other than the rather shoddy track record of working), is that is Windows only, no Linux or even Mac support...

The update is out and nobody's found any improvement. The tracks I've made in JPM are just as awful as ever. Are you expecting additional separate updates?

Nothing concrete at this moment in time... but that does not rule out any other changes.
What I find so confusing is Samsung were (are) adamant the Broadcom fix and later rectifications sorted out the GPS errors, otherwise we would still be waiting.

I shall reserve judgment until after the final tweaks which will be held in the UK release due later in the week.

Obviously I'm trying to keep on top of what is happening both here and with Samsung and will report back as and when I can.
 
Impression I get is that nothing was fixed at all in this release. It just updates Android 2.1 to 2.2 and thats it. GPS still useless, file IO still crap, wifi probably still broke too. What a sham.

I just don't get it.... It does not make any sense.
If it is as bad as a lot are saying why on earth did Samsung release it?
You can't say it was down to pressure because the kickback would have been more damning getting it wrong after so much time.

I'll wait until I see the UK release before passing judgment but I'll certainly pass on the feedback to see what they say.
