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...
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.

Thanks for the explanation =)
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.
ok so i bought a leather flip wallet for my streak heres link
http://www.ebay.co.uk/itm/190596988332?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
anyway, so when i get a call or make a call, my screen goes black and no matter what i do i cant get it ack on, the only way to get screen back is to remove from case as soon as i do it comes on again , is there a solution for this? how can a leather case cause this is it something to do with the magnets on the case?
i have no other issues other than that one which is why im kinda stumped as to whats causing it
any ideas would be appreciated

There is a possibility that the Dell Streak 5 has a proximity sensor that is being covered or activated by the new leather cover you've bought.
Seems logical, but it's worth checking up on.

Well i also have a carbon fibre skin on it and the case doesnt cover anymore than the skin, so dont think its a proximity sensor, thanks for reply though

I have an Otterbox case on mine, the holes for the sensors have been very carefully designed, despite the thickness of the thickness of the case, and it is very thick indeed. The holes are designed like funnels so that the outer edges are wider than the inner edges. I strongly suspect this was done because the sensors that blank the screen when it is close to your face is very sensitive. I've experimented with holding it to my face, I'm sure the case you got is fooling the sensors as it must be slightly covering one of them.
It seems the most logical answer.

i can see where your coming from witht that, but it doesnt cover the sensor at all, the weird part is, if i pull it half way out my case it does cover the sensor but the case then screen back on lol
Got a pic of the case?
From the picture in the link in the first post, the cut out doesn't look like it extends far enough to uncover the proximity sensor. The proximity sensor is next to the front facing camera.
Just my opinion from a poor picture. If it works out of the case but not in the case, logic would dictate that the case is the problem.

I should have said "better picture" but in reality I didn't look at the link.
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"

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
I read in the Note 2 forum that using flip covers that come with magnetic flaps interferes with the s-pen, gps.. Are they still present in the Note 3? I found a nice flip cover for Note3 but it comes with a magnetic flap. Having second thoughts about buying it because of the interference issues. Thanks for sharing your inputs about this.

You are correct. There is some type of interference where the magnetic field causes the screen not to recognize input in some areas. I just got a plastic and leather flip case with a button style snap.
Hope this helps!
Nice to know that the magnet causes interference. Will have to check out other flip covers for my Note 2.. Thanks a lot!

Well let me just input my two cents worth. I have a leather belt pouch with a magnetic button and I have not experienced any problem what so ever. On the other hand I place my phone with the screen facing my body.

I hope I didn't confuse you with my post.. I was talking about "flip cover that comes with magnetic flaps"... You're using "leather belt pouch with a magnetic button", is that the same as "flip cover with magnetic flaps"? Please correct me if I'm wrong, coz what I understand by "leather belt pouch" is it's strap in your waist and that's where you place your Note 3. But is the Note3 "attached" to your leather belt pouch or just place inside the pouch when your not using it? When you are using your Note3, do you still use it while inside your leather belt pouch or do you take it out from the pouch? Thanks for your input as it will greatly help us decide what case/protection we should choose for our Note 3..
