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.

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.

I have seen some magnets that attach to the case of a phone then connect to a metal plate on the car or one that connects to the vents of the car. Does anyone make one strong enough to securely hold the Nexus 4 with a heavy duty case?

I can't remember the exact sizes, but when I bought mine, it came with a few different-sized metal tabs, so you'd have a small variety to choose from.

Yes, it looks like it sticks on with adhesive to the back of the phone.
Yes that is exactly how it works. The adhesive does not work on some cases so I have sometimes used crazy glue. I've tried a lot of systems for in car mounting and this is by far the best in my opinion.

X-Way is great for using vents as your mounting point, but if you want to mount it ANYWHERE you want, then get the FIX-WAY.
I have something simple and a lot cheaper, you might want to consider.
Cellet Magnetic Holder
Here's a youtube video which might explain it better:

I can attest that the magnet is extremely strong. The phone will not move at all through any bumps when driving. You stick the magnet to the back of your Nexus 4. I never took off the protective back skin that came with the nexus, so I didn't mind sticking the magnet to the back of the phone. On top of that I use the Diztronic protective case covering the back of the phone. Since that case covers the entire back of the phone, it covers the magnet and you can't even tell I have the magnet on at all. the magnet still works great through the protective case and still extremely strong.

From the reviews it is larger, but stronger maybe. I ordered one in case I can use them together or the other one is not strong enough.
I built a magnetic car dock for the nexus4 that I'm now selling.

Here's a video of one of the prototypes showing how it works. The production version works the same except the magnet is stronger and it has cutouts for headphones, mic, camera, and speaker.

There is a metal plate at the back of the phone or underneath the case....not a magnet...
Metal may have a better effect on inductive charging....rather than hampering it...but this is just my guess...it may disable inductive charging as well....

i have a smartcover paid 5$ and works not so fine because the magnetic inside is not so heavy....
so the question is:
how strong must be a magnet to always work with the screen but not so strong to make the tablet having issues with?
i have 2/3 magnets but before trying with the fear of bricking is better ask....

The OP didn't say bricking; he said "damage".
And while there is no magnetic (digital) storage media onboard, there are other components which can be damaged by strong magnets - the prime example would be coil assemblies associated with speakers and microphones (if moving coil tech is used for them). Also it is possible that surface-mount inductors could have their properties altered if they got magnetized to their saturation point. (Depends on what they are being used for).
Take a paper clip and dangle it from a thread above the screen - you will find there are two speaker coils on either side of the USB connector - the closer of the two is only about 3.8 cm from the (apparent) location of the magnetic closure sensor.
@Pikkierello
I would encourage you to use elegance over brute force. A tiny and well placed magnet is a much better idea than a large powerful magnet.
The case that I have seems to work pretty well, and based on the "paper clip and thread" method, its' magnet seems to be located at about 1.1cm from the left hand side and 4.4 cm up from the bottom edge of the N7 (oriented with the USB connector down). Also - I'm not sure if polarity matters - but fwiw, the "pole" of the magnet in my case (the side facing the N7 screen) is the N pole.
You could buy some small magnets, but I would consider the costs involved - it might be less expensive to simply buy a different case.
good luck.
I bought this mount for my old galaxy s4, , and it worked fine.
It is designed so that you put a piece of high carbon metal in between the phone and the case, then you place it on the magnet and it sticks. It is a truly awesome dock, but I have a question. My S4 would not stick to it without the metal plate in the case, this phone will stick right to it without a case or the metal piece. This worries me.
Has anyone used a similar dock to this one, or can somebody let me know if this will damage my phone? I would just use it, but I heard that the camera's image stabilization is magnetic or something? I am hoping that somebody can give me some info regarding this.
Anybody?

Lol there's a magnet in the Quickview case
Sent from my LG-D803 using XDA Premium 4 mobile app
I also found out that QI chargers, like my phone supports, also contain a fairly strong magnet to hold the phone in position. The reason my phone was sticking to the magnet dock is because the QI receptor on the back of the phone (inside the back plastic) is magnetic so it can stick to the QI charging base.
Based on my research and my own experience, I am going to assume that it is safe considering I know 3 people using the dock have not had issues and my SGS4 was fine after a few months. I guess I answered my own question. I guess I was just looking for somebody who has used the dock for a longer period of time.
Thanks

I use tetrax. Not sure if you have seen them. But I have been using them since my Iphone. And currently using it on my diztronic case.
However, you must place the magnet as closest to the buttons on the back side or your wireless charging wont work..
I recently purchased a similar mount that the OP posted, but with a suction mount. I haven't used it yet but will post back after using it.

Thanks arson. I don't use wireless charging, at least not yet. The dock I have has about a 1" by 2" super thin piece of metal to put in between the case and the phone. The dock technically stuck to the qi receptor, but I didn't want to do it that way. What I am trying to say is that my metal piece is going to definitely cover up some of the qi receptor, plus I'd rather thave the magnet farrtger away from my camera if possible

If the flap\cover on your case triggers the window widgets and wakes\suspends the phone then, yes, it does have a magnet in it.
Not sure how far back the practice goes, but my OG Droid used the same method to trigger Car Home when inserted into the car dock. I took the magnet out of the dock to prevent Car Home from launching.

I have been using a Mountek (the guys who invented this) CD slot mount for three months or so, on Samsung Galaxy S3, Nexus 7 and LG G2.
No issues with magnets on any of the devices. You can wiki the topic.
Screen issues? No, we don't have CRT displays.
Storage? No, flash memory is not magnetic.
Compass? Maybe, hasn't affected me (Co-Pilot Standard, Google Navigation) YMMV
Location Services / GPS? No, GPS uses satellites.
Speakers? It has its own magnets.
Camera? If mechanical zoom, perhaps. Digital zoom, no.
While one can't believe everything on the internet, the consensus is overwhelming that magnets generally do no harm to modern smartphones. I'd be more worried about wireless charging, yet it's becoming mainstream.

You're right! I have located one small magnet
Now that I've used the iMagnet suction mount for a few days I can chime in. It didn't affect my GPS signal and it didn't affect my camera. I didn't purchase a QI charger for my Verizon G2 so I can't comment on its affect. But I do love the flexibility this mount provides since it doesn't use any gripping arms. I'm using an Incipio Dual Pro case with the round magnet between the inner and outer shell. It fits perfectly.

I have been using a QI charge rand the suction based mount like this.
Everything has been working flawless. No issues with GPS/DATA/ETC... everything still works.
No need to clip or adjust the holder for the mount. Its just put up and it works.
The only major downside? Well, two or three actually..
CONS:
1. The metal piece is small and thin. But it will still affect the way you use your case. Most cases are built to have nothing between case and phone. Even putting that slim metal piece makes it a little challenging to make just about any case sit flush. Including the Quick Window case, basic TPU case (which has worked the best), and my new incipio case.
2. Because of the metal, it usually affects NFC because it is right there. There might be a sweet spot to make it work with the metal there, but I usually have to take my phone out of the case or at least remove the metal. Main reason the cheap TPU cases work well. East on and off.
3. Pretty much the same as #2, but the metal also affects QI charging. Again, there might be a sweet spot, but I havent found it.
If you don't use NFC or use a QI charger and can deal with A LITTLE ill fitting on the case you own, then I think this is one of the best mounts out there.
I did not stick the metal I just have it loose in the case so I can remove it if necessary.
