Hey guys i'm having a hard time locating the nfc in my p10, everytime i use it it's hit and miss and dunno the exact location of the NFC. Where is the exact location of the NFC ? cant find it in the web. Thanks

The NFC chip itself is located ~1cm from the top, quiet centered.
The antenna, which is the important thing, is on the back centered and has a diameter of around 5-6cm.
When I use Google Pay I got the message, that I moved my phone too fast, very often. I don't know if it's NFC or antenna related. Maybe the aluminum case makes some issues, newer phones are made with glass, plastic or ceramic instead of metal.

Om youtube i saw a mod to increase audio volume, I tried it.
I removed the backcover, beside the camera I saw some tape and removed it, not knowing it was the GPS antenna. So now I can't get a fix on gps anymore.
I feel really stupid now.
Doe anyone know how to fix this, create a new antenna or something.
On the inside I saw some contact but I don't know which one is the gps.
I think it 's supposed to be on the left side as seen on the bottom picture.

Hope anyone can help me.
Thanks in advance.
I've read complaints of GPS and G-Sensors being out of whack, but didn't see anything on forum about compass calibration.
I noticed on my i9000 yesterday that while tracking myself on Google maps, that the compass should me pointing about 20 degrees to the right of the direction I was actually driving. In aviation, we call that crabbing, and it's normal based on wind, but not in a car.
I turned the direction my phone was pointing and the heading on the vehicle in the map started tracking properly. I guess my phone needs a little compass calibration.
Any idea where to this from? I'll dig around in the debug settings when I get some time, but hoping others might have found it already.
Thanks.
there are some free compass apps on android market that will display an actuall compass on your screen - and those will have a calibration tool you use when setting the compass up
No need for a special command.
Just turn the device 180 degrees and backwards two or three times in any program which uses the compass and it will be calibrated.
I'm a pilot too and I actually purchased a magnetic compass for my car and noticed the same thing. Haven't tested the phone's compass in my car though.
Are you forgetting some planes have Compass Deviation Cards to compensate for errors caused by the aircraft itself perhaps? Remember, cars have a significant amount of electronics, and a magnet in the alternator that can affect the direction of the compass (the magnetic flux created by the car is actually what triggers traffic light changes, so it probably isn't miniscule).
Btw, not sure crabbing is the correct term here (normally crabbing is isolated to wind I think). Correct me if I'm wrong (I'm still PPL).
Not sure about google maps, but I have noticed my hardware GPS (Navman's and that other rubbish which will be collectors items soon) actually use track, rather than heading.

I have a galaxy s and so does my daughter we both have a compass app from android market installed on our phones , both phones will not display the correct direction i have also tried a friends galaxy and his is exactly the same .
I have a xperia X10 and that displays correct directions with the same compass installed so i can only assume it is the phone at fault , i love the phone but this is annoying and i wonder if it is related to the gps problems this phone appears to have ?.
good old fashioned magnetic compasses don't work in my car, regardless of where i install them
it will always point EAST, very annoying, good thing it doesn't affect my GPS or my SGS i've yet to test the compass mode inside the car.
As i've taken it for granted no compass will work inside my car, as it has speakers every where and metals all around.
before there was such thing as a GPS, i used to be a good old scout and used maps + compasses to find my ways when driving in unknown streets

No, you're correct about crabbing...it's the term I learned for landing with a cross-wind and yawing into the wind to maintain your track to the runway. It's just what came to mind looking at the vehicle indicator and the roadway, it looked like a plane landing on a runway and that's what popped to mind.
Thanks to everyone else about the compass app in the market, I'll check it out.
Probably best to grab a real compass and compare to your phones one.. Then you'll know for sure.
But for GPS apps, track makes more sense because especially whilst driving, the phone has no way of knowing if it is pointed towards the front of your car.
(Btw, for non-pilots, when I say track, I refer to the direction you are actually going, rather than where you are pointed towards).
I'm a electronic engineer, A compass actually show where the magnetic field is more effective as North (and South) but what does make the differ is electronic compasses are more sensetive and may effected by a little change in magnetic field (for example holding a little ironic screw around it) so it may show wrong direction based on your country (and sometimes region). so the manufactors calibrate it on an avarage in order to make it working all around the world. but if it is not satisfying go to a service center they calibrate it for you!
(if you're geeky one you can do it on service menu yourself but it takes time to do a good calibration!)

HI, mdh_heydari
ok, but how to calibrate? even if it is time consuming and difficult. What is the procedure in SGS I9000?

There are 2 ways, the best one is some little fixes in android kernel and the other one is making mods for famous navigation softwares like Google Maps.
Recently I was getting a kinda weird effect. My compass now always directs to the bottom of the phone/screen, except when it is in open state. I think I have magnetized some parts somehow, and it is kinda disturbing when I want to use Layar or anything else what uses the built-in magnetometer.
Is there any way to fix this?
Theoretically putting the device into a simple depolarized magnetic field would solve the problem, but I don't know if it will damage the phone itself or not.

There are no magnetic components in the phone.
That means that it can't be magnetized.
I'm sorry to say that your magnetic field sensor itself is shot.
Note that putting the thing into a demagnetizer, if the sensor wasn't already dead, would DEFINITELY destroy it.
How do I demagnetize my cell phone screen
Actually phones have a magnet for the compass function and apps such as google maps to show which direction you are facing. Also, if you put your phone near magnets a lot it might magnetize metal parts in the phone messing up the compass. Demagnetized get your phone would demagnetize both the unintentional magnets and the magnetic compass. Please don't do that.
My gps cant lock without enabling.wireless connections (wifi, 3g). So im asking if someone else is having that problem. Im using 4.1.2 jelly bean
you are not using the gps but its wifi! so i fixed it by:
you can always do the gps antena hack.
i just opened mine and looked for gps contact point
its located above the rear camera.
theres a little coper spring like metal tha conects the main board
to the rear case of the phone.
if you examine it well.
the main reason we cant connect or lock that fast
its because the contact copper is not touching the small antenna on the rear case
that why soldering it or putting some folded paper(easy) bellow that copper spring will fully
push the conntacts between the mobo and ant.
then put it all back in. and try many app for testing gps lock.
i opened mine because its so frustrating that if with0ut this hack gps will lock more than 2-5mins which is b**s***
as i sc it before dou to other problem and they pull my waranty sticker,
so now i can freely open my unit and check things out as well.
now it locks much faster than before. but to tell you
"sgy-young" is way too fast to lock location about 8-15 seconds only!
i fixed my gps, (PLUS!) my:: wifi boost range and network boosted too!
i just solder copper wires inside to do the trick.
so goodluck! and you can do it! no need to use wifi or mobile data.
just pure gps!
it'l be solve, as it solved mine!
goodluck
I dont understand why i have to do this. Why didnt samsung fixed it properly.? So you re telling me that this is a hardware problem. This sucks i dont want to open my phone
Try use "FIX GPS" (google play)
Hey all,
I moved recently and now rely a lot on google maps (and other location apps) to go to places.
Whine the location of the device fave been spot on, I have an issue with positioning and vector... What I mean is the device reports direction with a 90-degree error. If I am on the crosswalk facing one of its directions, the phone shows me that I'm perpendicular to the crosswalk and when I move up or down the crosswalk, it shows me moving sideways... not sure how to explain it better...
If I'm in a car and moving, the dot moves correctly on the map but I'm being shown as moving sideways on that map...
After doing a Google search on the issue, it seems that other people are also having this problem.
I've tried recalibrating, using the live view to calibrate (which works for a moment and then breaks again) Also tried clearing the cache of google maps, (but other GPS apps are also affected)...
Does anyone know how to deal with this problem?
Try turning off improved accuracy or vice versa...
Clear system cache.

All of this has been tried. even board replacements does not fix it...
it seems to be some kind of a software issue...
Screen rotation is set to manual or automatic? Try switching your settings.
Google Play System Update is up to date? Should at least be from 1st March 2022.
we have a crab in disguise among us... 'transformers~~ shell fish in deguise~~'
jokes aside, the GPS is known to be very unstable. I have the issue come and go... and from what I've heard it's due to signal disturbances.
You'll want to report the issue to Google if you are using Google Maps
Use common sense (or develop it) to navigate.
Constantly being led by a smartphone on the streets is a lousy and dangerous way to live.
Develop a mental picture with critical way points of where you are going and then concentrate on navigating the real world by memory. With practice it becomes 2nd nature.
If it's a complex navigation effort break it down into manageable blocks with start/end way points.
For the car a dedicated GPS is more practical and reliable, but you still need to use common sense for when it glitches... and it will.
GPS is just an aid to navigation... like a map.
Do you have a permanent magnet somewhere inside your phone case, or other source of magnetism that would confuse the on-board magnetic compass?

KingFatty came up with my initial thought. Might be some magnetic interference.
I do know the exact issue you are talking about though. I knew I was facing south (I have an actual compass) but my phone said I was facing east. But I solved it with a simple recalibration. I have to recalibrate at least weekly.
You say you have had board replacements to rule out a hardware issue but if it was a software issue then surely everyone would have it? I can confirm that right now, the orientation is correct on my phone. It could be a firmware issue for your specific device but this requires the manufacturer to fix it.
That leads me to think its some kind of outside interference like a magnet in a case.

Samsung's don't like magnets, truth
It may be the earth's magnetic field in your location. It isn't uniform.
It's actually began a cyclical pole shift which will take hundreds of year to complete. Magnetic anomalies with become more common as the reversal draws closer. I doubt the latter could be the cause but the former could.
I think magnets may indeed be the issue. My bag's phone pocket has a magnet on its latch so it might be the thing confusing the phone. The problem is that from more than 20 different phones I had over the years, the S21 Ultra is the first one to exhibit such side effects from magnets...
I use a car mount with wireless charger, and the mount itself creates a magnetic field that confuses the phone's compass so the phone re-calibrates the compass based on the navigation driving etc. When out of the charger, the phone is still interpreting the compass as though it's in the mount with the magnetic influence, so you just need to recalibrate the compass and it will fix the issue until next time it automatically recalibrates while under the influence of a magnetic field.
That's just how compasses work, they sense existing magnetic fields, and the closer a magnet is to the phone, the stronger the field. If only there was a way to tell the phone you are putting it next to a magnetic field so it knew not to recalibrate itself at that time.
