Negative impact of permanent magnet on device - One (M7) Q&A, Help & Troubleshooting

I realized that the compass always hunts since I installed the steelie car mount; the metallic ring is actually attached on the UAG case and seems to stays very strongly magnetized since first install.
As soon as I remove the case the - mostly mapping - app I am using starts working fine.
Do you think the permanent magnet on the phone can cause issues, other than the compass loss? Do you know Google background services or other background apps even use that sensor?

[Q] Demagnetize phone?

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.

[Q] Phantom Taps, Bad Screens?

Does anyone have a solution for phantom taps on your NC?
I'm on my 3rd Nook Color when I pick up the replacement unit this afternoon.
My general issues are phantom taps - or the NC doing things I don't want it to. So far a very poor experience when typing, turning a page in a book, or even just navigating the ui. The whole issue may be me, it happens regardless if I am plugged in or not. I keep a very clean screen so there is very to little gunk.
I do have sweaty palms on occasion but not out of the ordinary. I have other touch devices that have never given me this issue. If anything I think the screen is overly sensitive - hardware or software issue?
Nope it's not just you. Mine has a multitude of issues with the touchscreen...
Essentially I cannot use the touchscreen when the device is plugged into stock charger/cable as wherever I put my finger, a random touch appears somewhere on the x-axis near my finger.
It seems that the device does not like changes in temperature or humidity either when it is unplugged. Using my tablet while cold was impossible, and likewise while it had been warm.
I'm on my second tablet from Best Buy-- the first one had dead pixels galore (enough to make the best buy rep say "dang!"), and now this one has a bad touchscreen and hard to press power button.
However: I purchased one of these for my mother a few days before mine at Barnes and Noble, and it has no issues whatsoever... at least not yet.
I've come to the conclusion that this hardware is quite beta, but I'm willing to give them a chance since it is the best bang for the buck, even if I have to go through a couple of returns... it's honestly almost worth the time for me since a tablet is so valuable for schoolwork.
Fortunately mine does not do this. I think maybe for those that are having this issue it may be able to be fixed in a firmware update.
My EVO had extremely similar problems when it first came out with the touchscreen and not being able to use the dropdown menu while the device wasn't grounded. After a firmware update the phone was great with touch sensitivity.
my first one did this also. so far the second is doing fine, but the first didn't have any problems till the 13th day of owning it.
i'm hoping it's just an issue that can be fixed via software - maybe someone put an incorrect voltage input somewhere.
I was having the same issues. I bought a screen protector and that seemed to solve it. So far, it's been working fine.
I noticed the screen protector stabilized the touchscreen a lot. Before I seem to have a problem finding the sweet spot for a touch. Now it seems better.
However, my phantom pinky is always touching something while I am trying to navigate. As long I only get one finger near the screen, it's fine.
Mine came from B&N.
The only other issue I have is the magnetic clasp in the cover seems to throw the internal compass/magnetometer off a lot.

Then how is it managing to correctly position the screen with Google Sky? Is it just spooky smart?
Mine only has problem when screen gets dirty. Try a screen protector or use gloves.
is there really a compass in this thing? I just assumed there wasn't. if there is I'm buying another tomorrow!
Screen protector helps to solve my problem.
Are you seeing more issues right after cleaning the screen? I see issues then and I think it is because I an using some moisture on the cloth. If I just dust it lightly with a dry cloth and live with a few finger prints there seem to be less of an issue.

Oh well, it could be worse although I don't see how Google data can tell which direction I am facing.

Nor can your Nook Colour.. Using something like TetherGPS would have some heading information, but the NC itself without help would not.
It might show 0, dunno there. Maps for me just shows a dot, if yours is showing different, that'd be... interesting.
For S&G I tried "Compass", it of course FC's immediately like almost all apps that try to use the GPS. Enabled TetherGPS (with no server, just the client) and it ran, but of course no data, no heading, etc.
Is this occuring when the nook is plugged in? sometimes the charger can cause phatom touches with the touchscreen. Cleaning the screen and being on a stable ROM usually gets rid of that problem.
If only I weren't so stupid ...

LOL! Ok, I sat down with it and played for a bit. It appears some tilt sensor is handling the up and down tilt. If you raise the screen over your head, it shows those stars and if you tilt it down, I see what is below the horizon. That is pretty consistent. But it's also "simulating" a compass inadvertently.
By that I mean that if I happen to turn it on facing north, it appears to track as you turn in a circle but it's really just me tilting it and it's rotating he view. If you do it enough it has no clue the direction it's facing.
I'm just glad I figured this out before I got lost in the Amazon.
Just got mine plugged it in and unplugged and within stew minutes phantom touches couldn't even reboot it im on cyanogen mod 7

Compass Calibration - Google Map Direction Problem

When using Google Maps on my HTC One and driving down a road, the direction of travel indicator on the Google Map (the pointer next to my location indicator) is never accurately aligned with the direction of car travel.
I believe that my compass may need to be calibrated but I cannot find any way to do so (figure of eight motion etc).
I have tried various compass apps and some offer the chance to calibrate if required (detected by the app) - none offer the chance to manually calibrate.
Any help would be much appreciated.
check out for metals near device, for instance my case contains a metal part that gets magnetized by the car mount, the compass never works with case on.. one other thing that might affect the magnetic sensor is the device temperature make sure it isn't hot when that happens. afaik you cannot calibrate this sensor as it's a magnet really so nothing to be done but maybe replace if defective..
one other app you can use to see how the sensor performs is the sky map or chart at night for instance to find a visible star or planet, that will tell you for sure if compass is OK.

Spen problems

Anyone else experiencing spen glitchy behavior? Example I'll be hovering the pen over the screen and it'll scroll or select things without me touching the screen and sometimes it won't register the spen touching the screen when I actually try to scroll, or I'll use the square app at work and when my clients need to sign the screen it'll register the pen before even touching the screen. I really like the spen feature but at this point it's too unreliable to even use, is this normal behavior? My wife's note 8 exhibits the same behavior. Tmo note 8 and we both factory restored before setting up and did clean install no transfer data crap.
do you have a screen protector ?
No not me works great and I use my Spen everyday.

No I do not, my finger touches are fine, it's only when I use the spen does it act glitchy, do you think it's defective?
No issues with mine on Verizon, with a screen protector.

Are you using a case with a magnetic kick stand?
My guess is yes.. can't use that with the Note's digitizer as the S-pen tech is magnetic based
If this is not the case (pun intended) then you probably have a faulty S-pen or Digitizer

I do in the car but I noticed this issue immediately after first spen use and I didn't have a magnetic car mount yet, so I don't think they are related and I don't use the spen when I'm in the car
Some of the Same
I also absolutely love the S Pen and I've had the note line for years. This time around with the Note 8 I'm experiencing a weird glitch that's happening with Google products ie Google Chrome Google app Google Maps. Especially when I use the Google app to read different articles. When I open the articles it will literally freeze and not recognize any touch. However if I open that article with my finger and scrolled just a little bit with my finger then I don't suffer the same problem but if I initiate scrolling with the S Pen it freezes every time. This is really frustrating to the point where I have to force close the app to get it to respond at all.... Google and Samsung please figure this out!!!! It really is maddening!!!
At least Spen works with no issue on my phone. I use it pretty often for making notes and also I found it faster and convenient to write in chat messages..
Try changing the nib. I had similar problems which seem to have gone after a nib change, maybe coincidental.
No problem on mine at all. See if you can borrow spen from somebody and test with different pen maybe? Also I would reset the phone and test again, before sending it back.
I exchanged the phone and so far it's been good, fingers crossed
Are you maybe triggering some of the events and tools that the S-pen does without touching the screen? One place this first "caught" me off guard was reading email. When you hover just of the screen it gives you choices and can do actions. There are also scroll choices in Chrome that fire up by hovering.
Just to make sure, I suggest watching
.
If it isn't behaving like in the video and you know you aren't triggering hover events, then I would definitely get it replaced.
I can't understand why third party case makers continue making cases with magnets in them for our Note series. It usually causes issues with the S-Pen. Like, a foldable stand can just be designed to "click" in place when not in use. You don't need a magnet for that. And for the wallet type cases they can just use velcro or something to clip it back into place without a magnet.
Any update? I also sent my phone in for repair of a similar issue and when I got it back, it seems like nothing was fixed. Samsung wrote that they "replaced cosmetic" whatever that means?
I had a similar issue with my note 7, as the recall started and I refused to surrender my note7, claiming warranty was not an option, I bought a spen, and, that solved it, to this day works fine, in this case with a note 8, you must go and claim warranty or, try with some one else's spen to sort the problem out
Thanks for the reply. Unfortunately in my case it seems like the s pen is not the issue. I've gone into a Best Buy and used their pen and I still encounter the same issue :/

I had the same problem when searching with Google and the result was shown in Chrome. Using the SPen and the site hang. Using my finger no problem. I then changed from Samsung Internet Browser to Chrome as default browser. The problem was gone.

Question 90 degree GPS Issue

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.
