Based on how a compass works, (magnetism) I would hazard a guess that there is NO software fix. Buy a compass. If it doesn't work, it will never work. Software can't fix a bad magnet. I COULD be wrong...I HOPE I'm wrong...I DOUBT I'm wrong.

Magnets are not software. ):

I asked T-mobile if there would be a fix for the compass along with the GPS on Twitter. This was their reply:

"TMobile_USA: @fjohnette That's what is believed causing the GPS problem so its possible we will keep you updated. ^SG"

[Vibrant General] caldjeff:
So this means it's possible that they will NOT keep you updated??

Anyway, I think we now have the word of every t-mobile CS rep and tech support person and most (if not all) don't really have any idea. I guess it's worth the effort to keep pestering. It'd sure be more comforting to have an official response.
[Vibrant General] Arr MiHardies:
You are completely correct in how a compass works... Basic magnetism... However. Just because our compass doesn't work doesn't mean the magnet bit isn't detecting north as it should. It could easily be that the other sensors that detect which way that magnet is oriented are reporting incorrect data, which is possibly fixable via firmware update. Or that the android itself is doing something wrong with that data, or any combination of the above. And these possible causes are far from exhaustive, just a few possibilities off the top of my head.

[Vibrant General] dex1701:
Yep, but every single thing about how that data is collected, interpreted, and passed on to the operating system is software, not to mention the interaction with the accelerometer sensors as Arr mentioned.

Lots

of potential points of failure here that have everything to do with software. Fingers crossed that it's not just a borked magnetometer.
[Vibrant General] bryon13:
Very true. As I said, I REALLY REALLY HOPE they can fix it... I'm just worried that we're going to be stuck with broken hardware. I'll never buy a phone on launch-day again...

[Vibrant General] hollabax:
this is my fear as well. It bugs the **** out of me to see people all over the forums violently defending samsung and saying with absolute certainty that a firmware fix is coming.

How do they know it can be fixed with firmware? I'm not saying that it's impossible, I'll be the first to admit I have no idea how the compass actually works, but to post saying that it will be fixed is so unbelievably stupid and irresponsible that I can only attribute it to buyers remorse manifesting itself as post-purchase rationalization.

Too many idiots to have any sort of productive discussion anywhere.

The compass is definitely the one thing that annoys me about this phone. I really like Google Sky Maps and 3D compass and right now they are worthless.
[Vibrant General] dex1701:
Agreed. The GPS issues are getting so much attention that the borked compass is falling by the wayside. I actually use the compass, so this is really annoying.
[Vibrant General] nricci:
you guys are brave

I returned the phone after a few days and decided to wait for a fix.

When/if the fix comes, I can easily buy the phone again.

To keep the phone is the same thing as keeping you anxiety level high, waiting for a fix, checking every board twice a day.

Is it worth it?
[Vibrant General] Morbo66:
Google Sky maps works fine for me. It does lag slightly when rotating, (which seems to match what others are saying about compass lag), but i don't see how it's worthless. It's dead on for me.
[Vibrant General] Jon C:
Have you tried Google Street View (Compass Mode) or Yelp's 'Monocle' / Layar?

The compass will sometimes point to magnetic North. But most times, it spins around wildly, or simply points to the wrong direction and does not update correctly.
[Vibrant General] MV10:
A friend and I bought our phones on the same day. Date on the stickers on the box (which I assume is a build date) is 7/17 on both of them. Side-by-side, Google Sky works perfectly for him, and doesn't work at all for me.

My compass points south no matter what orientation the phone is in, or what direction I face. Sometimes if I just stand still for a very long time, it'll slowly sort of drift in one direction or another, but I haven't had the patience to just wait and see whether it ever actually aligns with where I'm facing or if it's just random variation.
[Vibrant General] Spiffywerks:
Check my little video on youtube about this issue demonstrating how slow the compass reacts.

YouTube, search for: SvAJrR5Gmy0

or "Samsung Vibrant Compass Issues"

still won't let me post links yet....

I did end up getting the other phone working instead of pointing in only one direction. I factory data reset the phone and tried agan and it started pointing in the correct direction at least, still very slow.

I also suggest looking at sensor data to see how your phone performs:

[Nexus One General] GuestK0050:
Well supposedly AT&T is rolling out a software fix to fix upload speeds.

Funny thing is... for a few days my upload speed was fixed.

Now all of a sudden I can't break 200kbit up again.

But iPhone4 users around me can hit 1.4Mbit up all day long.

For those of you that can not hit HSUPA speeds, I wonder if you have iPhone4 friends you can check with.

If AT&T is indeed disabling HSUPA by device or IMEI, then I want to know about it.

It seems they gimped the Captivate so it couldn't do HSUPA (read the forum) so why not screw the Nexus One users too.

I know some of you will post that your HSUPA speeds are great, but you are people that are probably not served by Lucent equipment.

If you did have upload issues, and they are now fixed, I'de like to hear about that too, maybe AT&T is doing something else funky on a per market basis where it's prioritizing crying iPhone users where it doesn't have enough HSUPA capacity or something.

EDIT: My location is Salt Lake City

[Nexus One General] RogerPodacter:
i suggest you also post your location as well so it ads the detail necessary to make a conclusion. of course my speeds are fine here in socal with a nexus one. no cap or upload limitation or anything yet.

I test all the time with a friend of mine, we generally have the same results.

[Nexus One General] khaytsus:
Yesterday here at work in Central KY I was seeing 2/.2 mbit in Speedtest, today I'm getting 2.2/1mbit.

What's odd is 2-3 days ago, I was seeing the typical HSUPA speed but yesterday was horribly slow. Only reason I really noticed was because I was messing with wifi sharing and seeing how fast it was. Heh, just did wifi sharing, 3.7/1.2.

I've done it several times, uplink still seems weird.. One time it'll hover around .5mbit, then jump up to 1.2 for a few seconds, then back to .5. Next time I ran it it stayed at 1.2 the whole time. Next time .5 the whole time.

100% sure I'm not jumping towers, mine is very close to work. However, there's lots of folks on AT&T here at work so never know what the utilization of the tower is.
[Nexus One General] GuestK0050:
To be fair, I have to say that all of a sudden, I just posted 1405kbit up... But I doubt it will last. I would hope that whatever fix is happening will be for all users, but I am still doubting AT&T sincerity.

But I still think it's a valid question... are these AT&T upgrades targeted to fix certain devices in waves? Are others, like iPhone 4's being prioritized?

Seems weird that my phone won't break 200k, when an iPhone 4 will still break 1mbit all day long.

Could there still be prioritization going on based on device? Like say iPhone users made the news so they are getting bandwidth priority?

-James
[Nexus One General] EarthsiegeTA:
I'm not certain why, but I've been getting abysmal upload speeds for the past few days.

I'm located near Milwaukee, WI. Last few speed tests averaged out to 1.6mbs/.34mbs.
[Nexus One General] GuestK0050:
You could just be a victum of the HSUPA bug that AT&T claims they are in the process of fixing.

Are their any iPhone4 users around you having the same difficulty?

-James
[Nexus One General] Mi|enko:
Realistically, the only device that truly needs that fast HSUPA on at&t's network is the iPhone 4. The reason I say that is, it's currently their only device with video calling where that upload will really make a difference (besides data sticks and netbooks of course). Maybe they are randomly capping other devices uplink speed.
[Nexus One General] GuestK0050:
Well that's certainly one way to look at it but consider something else.

iPhone 4 users, and all other smartphone users who pay that $30, or $25, or $15... would then not be treated fairly.

Why do I get less service for paying the same $30/month the iPhone4 user pays?

This is blatantly wrong in my opinion. I'm paying for a service the same as iPhone4 users. In fact it's suppose to be the same service, that's why I started this thread in the first place.

There are apps like Fring on the Android Market that can make use of that higher upload speed, and let's not forget that the iPhone can't make Face Time calls over 3G as of yet unless it's jail-broken.

Now if it was clearly advertised that as an iPhone4 users you were going to receive preference, then I would have had a fair chance to make the decision as to which device would provide me the best upload, all the while paying the same $30 per month.

I don't think AT&T deserves to be allowed be deceptive in such a way.

Don't you want your service you're paying for?

In fact look at AT&T's website... it clearly states...

"typical upload speeds of 500 Kbps to 1.2 Mbps on compatible devices for our current 3G network*"

and...

"*Referenced speeds require an HSDPA 3.6Mbps/HSUPA capable device with Receive Diversity and/or Equalizer. AT&T is deploying HSUPA throughout the 3G footprint, HSUPA may not currently be available in all 3G areas."

It doesn't say... "Only for special people who worship Steve Jobs", it says for HSUPA capable devices.

[Nexus One General] stuff:
I highly doubt they are capping anything.
[Nexus One General] Memnoch30:
The video calling on the iPhone is WiFi only unless you jailbreak.

That said, I've been having the same issue. In fact, I went to return my wife's Aria because she wants to see if a high end phone comes for AT&T and while there, the sales guy saw my Nexus One and we talked about it. He said if I gave him my IMEI it would communicate better with the cell towers. My phone was fine but I figured what the hell, let's try it. And **** has been unstable ever since. I do speedtest and I get 64kbps down, 1.6megs up. Or they're both under 200kbits. It's driving me crazy. I work in downtown Chicago and it's pissing me off because I'm the IT Manager for my company and I need to get emails immediately. I've come back from lunch to find out **** happened in the office but my phone's data was so slow that it couldn't sync emails. :mad:
[Nexus One General] GuestK0050:
I'm not 100% they are capping anything, but I'm putting out my observations and seeing what others experiences are.

AT&T has my IMEI number and as of this afternoon my upload has stabalized over 1mbit.

I would like this to be for all N1 users of course. Sure is wierd that my iPhone friends saw the improvement before I did.

-James
[Nexus One General] GuestK0050:
I have been experiencing strange behavior as well where I am getting 1.6 (or a bit less) up and half the speed down.

Hopefully it's a symptom of implementing a fix and not a permanent situation.

EDIT: my download is highly irregular so I don't think it proves much.

-James
[Nexus One General] EarthsiegeTA:
Yeah, that's possible. I'm hoping that's what it is.

No, I don't know anyone with an iPhone 4. The only person I knew with an iPhone previous to the iPhone 4, I managed to talk into an HTC Evo.
[Nexus One General] stuff:
Maybe it just had something to do with your DNS cache or something..

You need to allow your GPS to lock before you'll get servers closer to you.

I have never had good luck with xtremelabs.

Speedtest.net usually provides more consistent results.

The company that provides it has a pretty large network for speed testing. The FCC speedtest app is provided by them, for what it's worth.

[Nexus One General] mykeldrip:

[Nexus One General] chromiumcloud:
I don't think they are capping upload speeds: I'm at 1.29 mb in NYC with a -93 to -99 signal (2-3 bars). The download, however, sucks balls.

I'm at 0.55 mbs download. I think this is a NYC issue though as no matter where you go the upload is faster than the download. If you go outside the city, then the download significantly increases.

Therefore, I would think that AT&T is capping download if anything.

It makes the most sense really, as when you what to check email, weather, news, etc., you really download a hell of a lot more than you upload.

Regardless, capping sucks balz.
[Nexus One General] URPREY:
On CM6 I noticed I had to edit the build.prop to enable HSUPA speeds for my N1. Once I did that and rebooted it worked great.

I set ro.ril.hsxpa=2 and ro.ril.gprsclass=12

same for me. every version of cyanogen ROM i've ever installed automatically defaults my build-prop hsxpa=1, which caps my upload speed to 384Kbps. everytime i change it back to hsxpa=2 and my uploads shoots right back up to 1.5Mbps. this only happens wtih ATT users it seems, as tmobile network must not listen to that setting in build prop.
[Nexus One General] EarthsiegeTA:
What's odd is that I have an ATT N1, and I'm on ATT, but when I change hsxpa=1 to hsxpa=2, my upload gets capped at 384kbps and my phone has a terrible time getting a lock in Google Maps, or any application for that matter. Not too sure what to think about that, lol.

[Galaxy S I9000 Accessories] carlocb:
Yesterday night I was playing with the phone before sleeping. It was charging not with the provided ac adapter, but with the usb-miniusb cable + an aiino usb-ac adapter. Well, the weird thing is that using google maps, the touch/multitouch control was completely f****d up. I mean, it was impossible to pinch-to-zoom, using the zoom buttons worked, but when I used only one finger to move around the map, instead of moving it was zooming randomly in&out without a reason. So I unplugged the cable and it was working perfectly... :eek:
[Galaxy S I9000 Accessories] Piny12:
It seems your 3rd party ac adaptor is not appropriately grounded so there is a small current on the touchscreen. Capacitive touchscreens recognize minimal changes in currents on the surface. That's why fingers, oranges, organic material work with it, but no stylus or other pens.
[Galaxy S I9000 Accessories] carlocb:
Hmm that's an interesting point, I didn't think about that. Do you think I should stop using that charger? Could it damage my device in some way?
[Galaxy S I9000 Accessories] Piny12:
I got it with my iPhone 3GS on a car charger too. But it didn't hurt the device at all.

I cannot guarantee this though...
[Galaxy S I9000 Accessories] carlocb:
I always used it with my iphone 3g too, and also used my iphone while it was charging...but I never had such an experience on iphone's multitouch...that's really strange!
[Galaxy S I9000 Accessories] changaz:
I had the same issue with a generic ac micro usb charger I bought on ebay.

Since the phone was just newly released, there seemed to be a premium on the chargers described as being for the galaxy s so I went and bought a much cheaper micro usb charger compatible with motorola devices. I figured the contacts would all be the same and all micro usb chargers the same.

Wrong.

As soon as I plugged in that charger, the touch screen was borked. The display was fine but the touch response was shot. If I tap the application drawer in the home screen, it would register a click on some other random spot on the display. The phone was utterly useless while plugged into this charger.

To troubleshoot, I tried mixing it up between the original samsung charger and the generic, resetting etc, and it always came down to the charger. Crap with generic, prefect with original.

TL;DR - not all chargers compatible with samsung galaxy s, borked touch response from generic charger.

Perhaps it would be useful to change the title off this post and move to the accessories forum? Useful for people to add their feedback on generic chargers they've used.
[Galaxy S I9000 Accessories] changaz:
Btw, the charger did charge the phone but I guessed having extra current run through the screen would damage the capacitive sensors.

Compared to the original samsung which has 4 contacts, the micro usb plug on the generic had an extra contact. I tried to open up the plug to see if I could do something about the extra contact but it broke and I the it out.

Shame I didn't think to make a video to share.

How bad is it to our phones ?....

I would like to know what is really happening.

Is the usb charger "ground" at an important voltage relative to earth ground ?

Is it at a variable voltage, which would even more confuse our phone ?

Could we safely ground it, and how ? (connecting the usb ground to earth, maybe via a grounded 220V plug ?) .

I think anyway I will at least mesure the voltage (and maybe leaking current relative to real ground) level of this usb "ground"...

Any electronician to explain how it is normally done in quality chargers ?
[Galaxy S I9000 Accessories] Rofa1:
I'm not sure what ground here is! My e-bay travel charger 4.7v 500mA with a Samsung logo has no ground connection on the charger - normal in Europe. Problem probably is that it is possibly not a Samsung unit at all - well it only cost 1euro - It does charge and the screen does freeze until I disconnect it. Only got it today - but nothing is getting hot and no other problems so far. The voltage rating is of course less than the standard 5v.
[Galaxy S I9000 Accessories] v205:
Bought a Belkin Dual USB car charger (1.0A + 0.5A) online. Will report back.
[Galaxy S I9000 Accessories] mtelep:
My best shots would be no ground (mass) issues, but:

1. stability of the charger output voltage

2. stability of the charger output current

3. value of the charger output voltage

4. capacity of the filter capacitors in the charger (too little - 50/60 Hz hum is distributed to the output)

5. Is the charger impulse or stabilized?

Capacitive screens must be very sensitive to changes of impedance and if there is no stable voltage or current or if the output is interfered with electrical network hum, the touchscreen may go crazy in my opinion...

edit: format tags corrected
[Galaxy S I9000 Accessories] v205:
Working fine without any capacitive screen issues.

The good thing is it works as charger mode instead of USB. So I assume the 1.0A socket would actually charge faster than USB mode.
[Galaxy S I9000 Accessories] TheBeano:
It will be high-frequency noise on the DC output voltage of the charger. Chargers use a high-frequency DC-DC converter method and the cheaper ones don't do a very good job of filtering the high frequency out of the DC at the other end. This noise enters your phone and plays havoc with the sensitive circuits in the capacitive touchscreen.

It is nothing to do with grounding of the input side of the power supply; when you ground the output side (the USB plug) with your hand, your body capacitance filters out some/all of the noise.

You could probably filter this out by adding capacitors or whatever but really, the solution is don't buy $1 chargers for your $x00 phone. ;)
