Question Magnetometer issue - Sony Xperia 5 IV

Apps reporting "strange magnetic field". Compass(es) shaking vigourously. Physics toolbox(es) reporting magnetic fields in xyz directions in the -120 to +120 uT range. Thats all about 4x the expected values. Resulting B calculated somewhere in the 20 to 130 uT range, varying with phone position in a reproducible way. Should have been constant and not influenced by phone orientation. Rotating phone along xyz produces qualitative results roughly as expected, but obviously with some serious quantitative errors.
Do you have a working magnetometer on the Xperia 5 IV?
Do you have any thoughts on how I might proceed to determine if this is a hardware issue, a driver issue or an issue with Android 13? I am having a hard time imagining how the magnetometer chip could produce this and thus suspect some firmware issue.
I use the Compass frequently, - but obviously not on my current phone.
Your ideas mutch appreciated.
Thanks!

Its hardware issue. I have that problem too .
I ve noticed it while my google maps couldnt get my compass to calibrate no mater how or how many times i would twist the phone . I ve tried with alternative apps sane thing happened.
This was noticed as soon as i got the phone ,that means it is ruled out as software issue. My phone was on android 12 ... Now it has few firmware upgrades and nothing has been changed.

Viper, - thanks. Saves me a lot of speculating!
I found a test menu in Settings / Support / Troubleshoot / XPeria Tests. Interestingly the magnetometer sensor seems to be the only one not listed. Could mean Sony is well aware of the issue and dont want it exposed. I then only need to know if a firmware update can fix this, or if it will never work on this phone. In the latter case I will probably return an otherwise very fine product.

I think they fckd up with wireless charging coils on assembly line and now they are interfering with that sensor or sensor itself its not working at all . Software upgrades didn't do anything so i dont think they will be able to fix that by software.
Its not a deal breaker for me, navigation still works fine. So in my case i dont think i will be sending my phone to sony ..

My compass works fine, but magnetometer is still missing in the support app. You can use a thirdparty app called DevCheck to chek if your magnetometer is working.

What do you think compass is and how it works.. compass does work relatively fine but it aint accurate

I was recently on a trip in Europe, and used my phone extensively for walking navigation. This is when I noticed the compass issue on my phone. Verified it with another phone next to it, and the compass readings were off by 130 degrees.
My GPS was also slow to acquire often times.
Sony said to do a software repair, which didn't fix it. So I'm not in the process of sending it in for repair. Hopefully they'll get is sorted out.

Hey which variant do you have?

XQ-CQ72.
After a comparison with my iPhone and Suunto watch, I think @viper. might be right, maybe the compass on the 5IV isn't very accurate after all.

Thought I would give an update.
I have had lengthy discussions with local Sony support about the original issue of this thread. They have replaced the phone. Same problem. I conclude that they do not understand, and have no intention of fixing.
The compasss does not work. Anything using the compass is close to useless.
The underlying problem is the magnetometer. Where I live the field is 45 uT and other phones return values between -45 and +45 along the xyz axes, and produce a vector pointing to magnetic N of length 45uT. (Use e.g., physics toolbox to view this)
This phone returns
-200 to 0 (X)
-100 to +100 (Y)
0 to +200 (Z)
The values are reproducible and use each of these scales fully, - so the sensor seems to work just fine.
However, If putting that into the formulas to calculate the vector, things will go seriously wrong.
Thats why I believe its firmware, and quite easy to fix. Just getting all 3 to return -100 to +100 would fix the direction and most apps would work as intended. The length of the vector (absolute strength of field) is not much used.
Above is about the XQ-CQ54 model.

[Q] Still have GPS problems. No help from Samsung

Hi,
I'm having an ongoing problem with my Vibrant not locking onto satellites. I've tried every trick, mod and software update I could find to no avail. After visiting Samsung's web site I saw that every time somebody asked a question about the GPS not working, Samsung's response was that it's a hardware problem and to send the phone in for repair. So I did and this is what happened......
1. I call and give them the exact problem I'm having. That the phone will not see let alone lock onto a real satellite. She emails me a 2day shipping label. I taped a note to my phone also detailing the problem for the tech to see.
2. I get an email a week later saying that they're shipping my phone back to me and this is what they did (Copied from the actual email).....
Original Problem:
Technical Inquiry
GPS
Acquiring Location
Problem found:
DROP CALLS
SW,PRL,OTSL RESET
Solution:
Passed All Functional Testing
After Google'ing what SW,PRL,OTSL RESET meant and finding out that it's just software resets, I called Samsung support back. I asked them if and why the hardware wasn't repaired and reminded them that their web site, in many places says that it's a hardware problem and to send it in for repair and that my phone NEVER DROPPED CALLS. She states that it tested ok and to wait and see. She then tells me that if I receive the phone and still have the same problem, they will find another solution so I wouldn't have to send my phone in again.
3. I received the phone last night. I put my sim and battery back in and turn on the phone. I did nothing but add my gmail account back in so I can download GPSTEST from the Marketplace. After doing so I walked outside and sure enough, after 10 minutes, no satellites. Nothing. This morning I called Samsung and to make a long story short, after talking to level three support, they tell me all they can do is have me send the phone back again.
Here's my problem with Samsung.... I followed their direction and sent my phone in for repair. I twice gave them the EXACT problem I was having. Their own website states that there is a HARDWARE problem. So instead of fixing the exact problem, they find a totally different problem to "fix" instead. They never touched the actual hardware or fixed my problem. They won't take responsibility for their error and find a solution that works. They tell me they don't replace phones, only repair them so they can't send me another phone. They won't even send me a overnight shipping label so I will only be without my phone for 5 days instead of 10. The only solution to my frustration he can offer was to give me an address to send a letter of complaint.
I'm done with Samsung. Is there anybody who can offer a solution to my GPS problem. From what I can tell, it is a hardware problem. Are there any fixes out there or do I just have to get another phone (It'll never be another Samsung)?
Also.. What other recourse with Samsung do I have? It doesn't sit well with me that I just have to accept their excuses and policies that do more for them than the customer.
Thanks
I had the same issue and I just had them send me a replacement. Just go through the live chat on your account, choose the warranty/exchange option, and then tell the rep that you tried all the fixes and updates and nothing works. It took about 15 minutes before the person said they would replace mine. Also, I would talk like you know more about the phone than they do.
Hope Samsung didn't break your gps connector tab
Gps is a hardware issue on vibrant and the best you can get is 25 feet accuracy and 30 sec lock times mostly.
In your case, you do need a replacement that can at least do this much

Why didnt you simply call tmobile and have it swapped?
Did you try the self hardware fix in this forum? Worked wonders for me and many others.

Was this with Samsung or T-mobile?
I had much the same experience with Samsung as cconnell11. I last talked with Samsung a month before 2.2 was available. They assured me that 2.2 would fix it, and there was no point sending it in since they didn't have a repair procedure for it and it would come back the same way it was. I asked what would happen if 2.2 didn't fix it. They said all I could do would be to send a complaint letter.
Naturally 2.2 didn't fix the GPS. I'm thinking about what to do next.
I tried the hardware fix today and I still do not see a big improvement. I have gotten mine down as low as 6 meters but no less. My old MT3G would get really accurate compared to the Vibrant. I have more issues with Wifi than I think I do GPS. I adjusted both antennas this morning but my wifi still isn't stellar. I wish Samsung and T-Mobile would just send you a replacement phone up front and repair your phone and re-use it as a replacement after they repair it. The whole 2 day shipping thing sucks when you need your phone for work.

Wow I only get 10m accuracy most of the times. I know other phones can get upto 6 ~ 9 feet
You can check here http://www.n2yo.com/whats-up/?c=20 to see what satellites are in your view.
If you get a different set you will have zero chance of locking on. If you show no sat numbers initially you are getting no or incorrect GPS assist to give you at least almanac info. If that is case try GPSrestore.
Do you get any grey bars on GPS test app? They need to be greater then 30 db/No to get initial data lock. It appears that Broadcomm GPS firmware does not report any sat lock until at least 3 satellites are locked enabling a 2D fix.
The only significant HW issue reported is the antenna contact. If for some reason the GPS TCXO calibration value has been lost it could take a very long time to get a lock, maybe never. Once it does it will establish a new TCXO calibration value which is then saved for future use. GPSrestore may retrieve factory firmware stored TCXO calibration.
GPSstatus does a network request for assist data that should get you at least correct sats to look for. Use WiFi if you have it with GPSstatus. Just use GPSstatus for assist download, then close and open GPS test.
I have not tried any of the hardware fixes (yet), but have tried the software reset from Samsung with not much change. When I notice that my GPS is having a hard time locking, I turn off Wifi and it locks almost instantly. I can then turn Wifi back on and it seems to keep a lock.
As an example, I can have a lock/see of 0/2 in "GPS Status" app for minutes. I turn off wifi, wait about a minute and get have 5/12. After turning wifi back on (after lock), I still have 5/12.
By comparison, my Galaxy Tab quickly goest to 7/10 with or without Wifi on.
Accuracy (according to Google Maps) is 10m on the Vibrant and 4m on the Tab.
I am thinking that my new golf GPS app is not going to be too useful with only a 10m accuracy.
thank me later
buy a bluetooth gps receiver such as globalsat bt-359 or any sirfIII or better. Next download bluetooth gps provider from the app market. let their powers combine and you vibrant may become a fully functional gps with the purchase of onboard gps vavigation. hehe
My solution
Since originally posting this I've tried the bending the pins up hardware fix to no avail. If I'm outside with a clear sky GPS status shows several satellites and after about 5 minutes will lock onto maybe three or four of them with about 10m accuracy. Maintaining that lock though is tricky. If I get into the car, it looses it. If I turn the phone upside down and have the bottom face the sky I get a lock on 7-10 satellites with about 7m accuracy. Either way it isn't good enough and I found a new problem. Google Maps just doesn't work with the default settings. It locks the phone up no matter what updates you've done. I fixed that though by changing the Operation Mode to MS Based and the Server FQDN Type to AUTO Config. Now it doesn't lock up and works fine with the exception of the GPS problem. I looked at the Samsung car cradle and noticed that it holds the phone sideways so the internal GPS antenna is facing the sky. This should work great but I don't want it attached to my windshield.
My main problem is that I want to use the phone for Geocaching like I did with my LG Optimus. That was a great phone and the GPS was accurate to 5m consistently. So I went ahead a bought a bluetooth GPS receiver. After a lot of research I decided that the Gosget SB-369 was the best option and it was only $30.00 online. This thing is great. I get a good steady lock on 7-10 satellites with 3m accuracy. This is perfect for Geocaching and was better than my Magellan when it worked right (don't buy anything Magellan). It has a hole in it and is small and light enough to be worn around your neck with a lanyard while Geocaching. You could also just put it in your pocket. It's antenna isn't a standard patch type. It's internal, but round and omni-directional and maintains the same lock no matter what way it's facing. I would recommend this to anyone who needs good accuracy for things like golfing and Geocaching.
I'm going to use this as a solution. I get great accuracy that I need at the expense of having another little gadget to carry.

[Q] Malfunctioning Compass on Galaxy 5.0 WiFi

Hello Developers,
I bought a Galaxy 5.0 for my brother and we love it. One problem we have though, the compass doesn't properly, I hear because of the 2.3 upgrade. I've rooted it with enropy's daily driver and I've played with some roms, (CM9 ) But I'm looking for a rom that has a working compass that is at least relatively stable. I would even consider downgrading to 2.2. A bug fix from Samsung probably wont come, so a fix from here is much more likely.
We tried to use the player as a gps and the map kept spinning because of the compass.
The software we use for the gps is Copilot.
Any ideas?
the compass on google maps/navigation works fine for me on gingerbread. have you tried that?
The map looks fine, but the pointer may spin in many different directions or stay in one direction. The other app I used, spins the entire map based on the compass, so it became unusable for pedestrian directions.
try turning on sensor aiding on the location and security menu in settings. (mine was unchecked, i checked it and got a super fast lock on my location) if its already on, try it without. you may be near some magnetic fields that are screwing with your gps.
Hey, thanks for the tip. I already tried it with both the box checked and un-checked, and still no help. Here's a video I found on youtube with someone with the same problem. youtube.com/watch?v=PnPU4UV_ywI[/url]
that happens to me sometimes but i just put it on a flat surface and wait until the gps icon on the status bar stops flashing and its usually fine.
if your arrow doesn't stop moving or the gps icon doesn't lock after maybe 3mins then the issue might be the whole magnetic field thing.
The compass on other devices I used in the same place worked perfectly well, and putting it on a flat surface doesn't really do much to help it, because it become erratic again when you pick it back up. It's more apparent in any compass app. On my phone, it always points north, even if I spin or move. On the SGP5 it just points to a direction and stays there , then jumps to other directions that are wrong.
I've noticed the same thing. I don't think it's a matter of finding "the right thing to try". I suspect that it's either the device or Samsung's implementation. I hope for a Kies update someday.
Yeah, but I heard it worked before the gingerbread update. I wish I know, but mine came with gingerbread already installed.
so did mine. although i didn't spend much time on stock before i switched to another rom. Right now I'm running my own custom rom that I may release to the public when I think its perfect, you may try that once its released since I told you myself I have no issues. If you want an immediate solution you can try these off the top of my head:
- go to task manager > maps > wipe data
- reflash gapps (20110828 gb version)
- clear cache/dalvik in cwm
I'm probably dumb and maybe that has nothing to do with fixing it but hey, if you haven't tried it already....
Try waving the device around in a figure 8 (Only using your wrist to do the motion) . I know... weird but it helps with the spinning compass issue.

Compass or Gyro?
I think that somewhere in the programming that the compass got mixed up with the gyro because even when left untouched mine still spins rapidly. When it does stop it almost always points the wrong way. Try an app that is supposed to find metal, when device is placed on metal the metal readings fade to zero, but if you stand in the middle of a field and shake the device the sensor will go to maximum.
I have this problem that has been described and haven't had any luck finding a solution. I bought mine in February with gingerbread. Why would Samsung sell these galaxy players without fixing the gps?

[Q] GPS not working

Hello, I was using GPS a lot during summer on official ROM, but after summer, when I stopped using it, I've managed to switch to custom ROM. I wasn't using GPS, so I didn't know that it isn't working. Now, I tried many ROMs, including the official one flashed via KDZ. Nothing is working, so what should I do? I have fast fix, but when I start moving, even if it is 2-3meters the GPS goes nuts and lose the signal:crying:. Any advice please?
I had this. Unfortunately, was not software related in my case (although I also flashed a lot of ROMs). The sat fix was fast, but very unstable in movement, rendering navigation software useless.
Turned out the culprit was bad contact between GPS antenna and the mainboard.
The workaround: removing the battery cover, apply pressure over the GPS antenna (like trying reseat it). I made it several times, but if you try this (at least, you will see if your issue is the same as mine), please be VERY careful, or you will end up with a broken screen glass, or mainboard.
The stability improved 90%, but the precision is not the same as new (but I can use Google Navigation and tomtom again).
I downloaded the service manual, the correct is disassembly the unit and check the contacts, but I don't have that tiny philips screwdriver. Time to leave the unit in a Service Center, and get the contacts cleaned/checked.
PS: The GPS unit in this litle beast is very sensitive, but LG's quality control in assembly probably is to blame.
Thank you, I will try it when I will have a chance .
EDIT: Didn't worked, I will try it again tommorow... or send it to the service
Molitann said:

EDIT: I think that I overpressed it, because it can't find any satelites and when I start any app that is using GPS, the gps icon doesn't appear... I'm so stupid . So, only chance now is to buy a new antena or go to the service.

My god! Sorry about that...
But are you sure the gps hardware is activated (in Settings?).
In software (ex: GPS Test), status is showing "No GPS"?
I've just edited my post, it's ROM issue (stock ROM shows the icon and about 5 satellites, but the CM doesn't show the icon and I can't get any satellite), the gps still sucks

AMAZFIT PACE - Compass

Hi! i'm Boris.
On my amazfit pace, since 1 week, my compass doesn't work anymore, and that's why my elevation gain sticks at 0..... I never let it down, i made a factory reset, update, restart... etc... nothing!!!!!
Somebody as an idea what going wrong???!!!
Thx for your answers.
Do you have a magnetic wristband?

No!!!! It works 3 months and suddenly nothing..... Is it possible that the MTB shocks break or weakens the compass? My Elevation Gain also sticks at 0, there is a relation??
THX for your answer fzelle!
Yes, when the compass isn't working, elevation isn't as well.
As it is not a mechanical part, I doubt that you can break it with riding MTB.
Tried a restart?
Yes... shut down-restart, factory reset, smartwatch and apps update....
Maybe there is a way to disable the compass after a bad setting?
It's a strange situation....
...... my air pressure is also sticking on "loading" (outside in an open space)!!!!
Maybe pressure captor's hole is clogged? It's the small hole on the side at 9H, isn't it?!?!
Too much suggestions...... i need to understand.....

Same happened to me and I don't know if it's related to a high battery draining (less than a day)
Can it be Software related?
the same here! battery and compass issue
I'm having the same issue. Did reset and using official FW but compass is not working and battery dies really fast. I'm outside of china and the return fees are quite high. Have anyone tried to fix it by themself? I do not have the best experience with Gearbest support.
Hi all,
I have the same situation, few hours of battery and compass stuck on 0°.
This is my experience: after a month since the purchasing, suddenly, the battery started to last max 8 hours (it was 5 days with continuous HR monitor before! ).
I asked on my custom rom Telegram group about this and the general answer was that it was due to the charger I used, too powerful for the watch, and that I had to use exclusively my laptop's USB.
Little by little, it went up to 35 hours and I was wondering if it may be resolved with a battery calibration (if exists).
Didn't noticed the compass issue at that moment, but now that I found this thread I see a correlation.

That is complete and utter BS.
It has nothing to do with too powerfull, what happens with most cheap chargers is that they have spikes in their output.
To prevent that, just use a powerbank, that's the safes option.
same problem
I also have the same problem compass and barometric pressure are also not working
SOLVED
I have some trouble, n its solved.
I have try to reset many times, not work. Try to downgrade firmware(cause i use latest), not work.
Try using small magnet(from refrigerator door accesoris) with power is on, not work.
I, ve given UP. just try to charge the wacth on flat position, try using small magnet with power off.
I didnt cek after that, but when i wear the battery life normal again, then i check compas is normaly again.
u can try
note : rotate the magnet on watch
For me, it started with new update. Anyone else?

GPS not accurate at corners in a square

Hi guys,
I was using the Pace in a running track and it was perfect. Now I started using the Pace to run around a square (which has a square shape), but it is not accurate at the corners. Due to that, I am getting speeds like 18 km/h and I ain't capable of that, for sure. Is there any fix?
Thanks in advance
GPS is measured every few seconds, so if the first one is before the corner and the second one after, there is nothing you can do.
Runkeeper has a function to edit the track and follow the road, that might help ( fitnessyncer can transfer from strava )
NoThanks for the reply.
It makes sense but it is frustrating to see that much error in a single run.
I was thinking if using a gpx file of the course would help to force it to stay on the track. Have anyone done that? Also, it is a circuit, so I am not sure how to make a gpx file for that.
Find attached some photos to see how bad it gets.
1. Make sure you sync watch to Amazfit app often in order to have A-GPS data always up-to-date;
2. Wait a few se seconds before you hit GO to start recording the active in order to get a better GPS fix (more satellites);
3. Tress and buildings can block/reflect GPS signal, adding noise so you won't get a good signal.

- I updated the A-GPS a couple of days ago. I am a little afraid it has something to do with it. Is there any way to force another A-GPS update?
- I always wait for a GPS lockdown. Generally, I hit the run option almost 200 m before starting to run and wait for the green signal.
- I will try to run in an open space just to double check. Maybe the trees are indeed what is making this much noise in the signal.

If you sync daily, probably it is fine. I am almost sure that A-GPS is synced only once a day. You can always force a sync by pulling down from the top on main Amazfit page, but if A-GPS data is up-to-date it won't show anything related to GPS, only sports/health data sync.
Not sure what you are expecting.
1) GPS is creating a trackpoint during running aproximately every 2s. Between 2 points set a diagonal is artificially created!
2) A very good gps reception has an accuracy of +-3m (I think +-10m is more realistic), you will not get it more accurate with recent GPS technology!
3) There are allways signal reflections etc from trees and buildings which are falsifiing the result.
3) You didn't specify the distance one circle represents, but from the building I guess you got quite reliable results.
4) If you know the distance of one circuit you could use the more reliably time measurement to correct the results.
5) A-GPS data helps to get a quicker satfix but is not generally improving the reception of the GPS signal.

Can you try it in Trail Run activity mode and see if that makes a difference? Another poster claimed the trail run activity gives more accurate GPS readings, but I am not aware it has been proven yet.

1. Ok, but I am not making that corner in less than 2 seconds. It should get an accurate read once in a while.
2. I see, but I believe it was not supposed to be all zigzagging like it is actually doing.
3. I agree that it is the most reasonable explanation for the inaccurate readings. It is not only the corners, but the entire track also gets faulty readings.
4. Yeah, but if I were to calculate the stats by myself I would not have bought a smartwatch. By the way, the square has a perimeter of 720 m, being one side 250 m and the other 110 m.
Anyway, thanks for all the suggestions

I will try that! Since the square has some trees maybe the trail mode would simulate/expect the same environment. Thank you!
