Just thinking outside the box here, would appreciate some input.
Most of the cases that I've seen have magnets to keep the flap closed.
Is the magnet on the case strong enough to affect the phone at all? Particularly the miniSD card, both the internal and/or external.
Last time I've checked, magnets and storage cards don't mix well....am I missing something here?
I can't say much as for the cards, but I do recall magnetic flaps did cause havick on the G1's internal campus.
It shouldn't, but it will affect the device's magnetic compass, requiring u to reset it by waving it around before using a compass app. It obviously won't work within proximity of the case, either.

I have my old TP2 case which has a metal+magnetic closing flap, and it hasn't caused me any problems.
I bought a case with the magnetic flap when I bought my Vibrant. So far, no issues because of it.
Hmm.....well I have a case with a magnetic flap too and after about a week no issues have come up...

Hi, All
Just bought a case for my Nexus one. The Case contains a Magnet to close the flap on the case.
I was just wondering can a Magnet harm a Nexus one!!?
Thanks

Shouldn't you be asking this in the N1 forum?
Magnet cases are pretty common, but not necessarily perfectly safe. If your phone has a magnetic compass in it, you will definitely INTERFERE with it, you could even damage it if the field is strong enough.
I believe that N1 does have a magnetic compass.
If you don't care about the magnetic compass, you can go ahead and expose it to strong magnetic fields -- there's nothing else that could potentially be harmed by one.

Wrong place but you know that.
Asking if a magnet can hurt any electronic device is like saying will putting a bomb in a public place that is crowded will kill anything.

Not correct.
Magnets typically will NOT affect/harm electronics unless the magnetic field is ***EXTREMELY*** strong -- so as to disrupt the flow of electrons.
Alternatively, if the electronics have some magnetic field sensitive apparatus, like a MAGNETIC DISK or a MAGNETIC COMPASS.
Phones do NOT HAVE magnetic disks.
The only magnetic field sensitive apparatus on these phones is the MAGNETIC COMPASS.
The only way to affect any component of the phone ASIDE from the compass is with an ****EXTREMELY**** strong magnetic field.... I.e. MRI strong.

Doesn't flash memory count as magnetic field sensitive?
My blackberry came with a magnetic case and although it didn't have a compass, the phone never had any side effects after years of use.
If your phone is under warranty or you have insurance, I'd say go for it. You're probably safe.
Moved to Nexus One forums.
And to repeat what has been said before (by those that are correct, I mean ), the magnet would have to be INCREDIBLY strong in order to damage the phone. It will interfere with the compass, but should not cause any serious harm.

Can a magnet have a negative effect on my phone screen? I just bought a case the features a magnet clasp.
My understanding is that the Super-AMOLED display is not affected by magnetic fields.
What about the compass?
Unless the magnetic field from the case isn't strong enough to distort it; not sure how much is needed
You will be fine.
Should have no effect unless the screen is operating, the magnet is 3 times the size of an MRI machine's permanent magnet, and the phone is moving through its field at 100 MPH... (the only effect you could get is electromagnetic induction, which would run a current through anything.)
I have the Samsung Galaxy S case, which has a magnetic clasp. It messes up my compass calibration almost every time I put it in, but that problem is quickly solved.
What is all this compass stuff I am hearing about, I just got the phone 2 days ago is the compass that important/ how would I fix a problem with it?

I would wager it uses a fibre gyro compass. The odds of having moving parts inside the phone for the sake of a compass is pretty slim.
Gyro compasses use voltage fed sensors and that is why they (and our phones) need to be calibrated. They are not susceptible to magnetic interference.
I could be wrong, but I would be shocked if they put a magnetic compass in a phone so that it needs to be converted to digital output rather than just put a cheap no-moving-parts-to-break gyro in it that is already digital.

No problem. Here's some other reading on it if you're bored

So the consensus is that I'm safe with the magnet case right?

Yes. You'll be fine =)
Random tidbit: If you put a magnet against the camera lens, it will turn your phone on. I'm using a HD magnet but it might work with a weaker one.

This happens due to the the magnetic sensor used for the car dock that we never seemed to have gotten. It should keep your screen from going to sleep and, if you were to have the Car Dock application installed, would launch the application.
Discoloration
I bought a case with a magnet clip.
After only 1 week i got a brown-colored spot 1,5 cm in diameter just where the magnet was situated.
Now a couple of months later, the spot is still there.
Don't know how to get rid of it.
I don't often post here, and and I don't know if this issue has been addressed before, but but I'd like to tell you about my experience with the note:
I received the phone just today, and after bying it online.. All was good, and I already had a case (a faux-leather flip case), waiting, and and put it in immediately. After playing with it for a few hours, and I noticed that there was a dead spot on the screen. But only when using the s-pen, and a few hasty emails and a phone call to Kogan (off whom I bought the phone), revealed that this was a inhear-of-before phenomenon. As of writing, I've yet to receive word whethery they'll accept a return.
However, that would be rather pointless, and since I have since fixed the issue. It seems that the magnet holding the case flap closed was pretty powerful, powerful enough, in fact, to cause the active digitizer to stop working on that of the phone that the magnet was under. After I removed the case the s-pen worked in the spot, as well as the rest of the screen.
So be warned, test your cases if you can before you buy them, especially if they have a magnetic clasp or similar.
(sorry for the prose)
I have been avoiding magnets because of several posts on the subject. There have also been several stating there are no issues.
I prefer to remain safe, and I am grateful for your advice. Magnets near a device relying on magnetic resonance are probably not a good idea. Better safe than sorry IMO.
Strange how some people have this problem. My note has been sitting in a magnet case for 4 months now with no such problems. I guess it depends on the case and how strong the magnet is but I could not do without my case so I will carry on using it for now.

I think it also depends on where the magnet is. Mine was on the back, directly behind the device.

I agree. More testing, and definitely more information from Samsung, is required.
I wonder if it is the TYPE of magnet, not so much the size.
If it is one of those cheap magnets, maybe it won't bother it
as much as the stronger neodymium magnets?
thanks
thanks man.. for sharing this..
I also have avoided the magnet cases due to this fact and have been trying to find cases that use some other alternate means for closure, like maybe velcro instead. I was also even considering that Sweet Case made out of aluminum, but at ~$70, it is rather pricey. I have just been going case less and totally naked with it and so far no problems.
IIRC there is a comment about magnetic fields in the manual...
similarly too, there is a comment about electrostatic fields, so if you are in an environment where sparks fly off your fingertips at intervals be SURE to discharge yourself before touching your SGN.. you may kill the touch response of the screen..
been there, did that, luckily it was a $50 C/H digital thermostat.
EDIT: 2 April 3:00pm
found it: Page 25 of the GT-N7000 Quick start guide states
"Do not store your device near magnetic fields"; and inclusively states "Do not use carrying cases or accessories with magnetic closures"
Man, I guess I have to quit being a Dark Sith Lord. But I have so much fun using Force Lightning to kill all those annoying Jedi do-gooders
I have a Tridea case with a magnet. The magnet is in the part that locks the cover to the back of the phone.
If I fold that piece behind the phone, there is some influence from the magnet. The influence disappears if I leave some space between the magnet and the back of the phone.
It is only a small problem for me, and only noticeable when I play Draw something or similar apps.

magnets, how do they work??
I have the same issue, I strapped a powermat charging coil to the inside of my casemate tough case, the result is a dead spot directly above the magnet in terms of the spen.
My dilemma is whether to forgo use of the s-pen for the ease of wireless charging.
For the moment as I rarely use the s-pen, the inductive charging coil is staying in place.
The s-pen works as soon as the powermat coil is removed but I'm not sure if it could do lasting damage?

That, my friend, is one of the great unanswered questions of the universe. Gravity is another one. We know what goes on, but not always how. It is mostly at the atomic level, although you have to look into the quantum level to find out more. One day we may figure it out!
Thanks for the warning! I doesn't use a case with magnets, but it's always good to know if I ever would.

Signed up to say thanks OP. I too had this situation where i had dramatic penmark deviation on my note. I use notebook style case w/ magnet
I was considering getting it swapped under warranty but then realised the odd behaviour happened in s-memo but not in canvas/paint app. Now i know its the location of the rear magnet on my case. gj op
Anyone doing this (using a case with a plate in it and a strong magnetic mount in the car)?
I noticed some flip cases will wake the phone when opened so the phone prob has a magnetic sensor in it. I'm concerned a magnetic mount may keep the phone off!

Hi,
I'm using this kind of car support with my OnePlus 5 without issues till now. [emoji4]
Thanks
have been using magnetic mount on my car with multple phones in my Car for more than a year now, never had any issues.
The same here. I have been using magnetic plates with different phones (well not with OnePlus 5 because I'm still waiting for case ) and there wasn't any problems.
Yep. I use the Spigen magnetic car might (the round one). I use on my Nexus 6p and now on my OP5. I actually put it in the phone and cover it with a dBrand skin. Works perfect, no issues with phone and does not interfere with my God which I use 4 days out of the week for work, 2-4 hours a day.
I don't use a case with my phone's as I've never dropped a phone and like then naked, so the magnet is strong either the phone as a card isn't there to weaken the pull. With this setup, I have zero issues.
I've been using Tetrax Xway for years without any issues (including with my recent Oneplus 5).
Hello, i just received the magnetic flip cover case for my LGG6. I noticed it has magnet on the left side. I read some articles that magnets can damage mobile phone sensors. Is this true? The case is wonderful but i'm having doubts if i will use it or not. Any thoughts or somebody having problems or issues using flip cases?
The magnet isn't strong enough to cause any issues. Wanna get a 5kg rare earth magnet it might cause a problem.
My flip case worked fine and the G6 has a sensor so it knows when you close the flap and locks itself, it also had a larger AOD than without the case.
The case I had was almost a matrix see through type that came with the phone.
