Magnet affect resistive screen? - Touch Diamond2, Pure General

Hi, I got an htc pure, and I was wondering if magnets o a strong magnet field damage the screen o some others components? I ask this question because nowadays theres a lot of case that have magnet to close them.
Does the magnet affect resistive o capacitive screen or other components in htc devices when they are close and a for a long time?
Thanks for your help.

A magnet can most certainly damage a phone, but it would have to be direct contact.
Main effect would be to wipe the data from the processor.
Not sure about the screen but I wouldn't chance it.

I have one of those cases that has a magnet to close them. I too was concerned but I haven't had any issues at all.

Yeah, I think those magnets are too small and not directly contacting.

Screen protector

How do we install the screen protector?
There's already a layer of clear plastic on my HD (out of the box) that covers the entire screen, inc the buttons and has a cutout for the earpiece. Is this a screen protector ?
I tried putting the screen protector that comes in the box, over my screen, it has nothing to anchor to, there's no earpiece sticking up etc, everything is totally flush thus my query above.
If the thing on the HD is not a screen cover, how on earth am I to install this spare one? Do I need glue? I cannot find anything about it in the manual?
Some clarification would be really welcomed
thanks

Do not put glue on you're screen! Damn!
And the "plastic" that's on you're screen, is not the screen protector. It's almost the other way around. If it was glass, if wouldn't scratch, like on the iPhone. So, due to that plastic, it scratches quite easily.
As I do not own the HD yet, I don't know how to apply the screen protector. I would guess it just sticks on.
Could we have some clarification on this please?...
The plastic film that's on your phone in the box is just to protect it (persumably through manufacturing, packaging, transport etc), you need to take that off.
I've never found the HTC screen protectors much good, didn't even bother to try and fit the one that came with the HD. If you search the forums you'll find links to better options.
Thanks Bungieman
You prompted me in the right direction. The screen protector is a peel back sticky (dinnt realise that before). I have just installe dit now, was tricky to say the least.
Another reason to be pissed off. You pay a huge sum of money and no glass screen. And no instructions or clarification for the micky mouse screen protector they give you.
Since the HTC Touch HD uses a touch screen, which actually needs you to apply pressure, a glasscreen would be way to "hard" for it to recognize any touching.

so what about the iPhone and iTouch then? its my understanding that they use glass screens, they cannot be scratched and there is no need to be sticking little pieces of plastic all over them
They use capacitive touch-screens. I think they respond to heat, or electricity, meaning that they cannot be used with a stylus, but needs no pressure to work.

gt112,
Usually we need to have some water applied on the device first, then place the protector over the device. The presence of water will prevent the protector from sticking to the wrong position. Then, using something like a credit card, you repeatedly swipe over the protector in such a way that you maintain the correct position, as well as dispel the water under the protector out. The dispelled water will make the protector stick to the device. The main point is to ensure there is no air between the protector and the screen surface.
Good luck.

Electric current, produced by the big walking batteries we call humans.
Messes with the "capacitance" under the glass of the iPhone and it's recognised as "touching".

Yes , the same technology Samsung used for the F480. A shame HTC didnt choose it either, because it works really well - at least if someone doesnt necessarily want a stylus.
Anyhow, the is the shipped protector an adhesive layer? Could it be easily removed and applied again?
the touch screen works for iphone, without the need for stylus, because the all the buttons are big. on WM devices, once you get past touchflo you are back in the realms of small icons whereby sometimes it's easier to use the stylus.
but the HD still rocks, so far i've only needed the stylus a few times.

I actually knew that.
Sometimes I find it hard to explain things, as I am not used to doing that in English.
But, one thing I'm wondering, is that many people keep saying the screen on iPhone won't work if your finger is cold, or wet. A wet finger would just lead the electric current even better, wouldn't it?

Yes and maybe. You can remove it without residue, but I had trouble cleaning it, so I just used another one.

Hi Eaglesteve, are you serious about applying the water ? Are you referring to the official screen protector from htc? i am using its pressure sensitivie adhesive (PSA) and that's it .
Indeed, the original screen protector is pretty good: it is essentially impossible to notice its existance since it is perfectly cut and there are ZERO bubbles if you apply it correctly e.g. carefully without touching the surface and carefully cleaning the screen before. In addition, the "slide" of the finger over the screen is even better and it's very easy to clean - just rub it on your clothes!

touch screen earthing problem??

Had the HTC hero phone through carphone warehouse on contract with voda for 3 weeks now happy with everything apart from the keyboard. When the phone is laid flat (placed on a table) the outer keys on the keyboard q,a,p,l and delete don't seem to be as responsive as the middle keys f,g,h. Only when earthing the phone with your finger by touching the metal frame part on the phone whilst pressing the key it becomes more responsive, can anybody confirm this ?
More to the point is this a hardware issue, this is my 3rd handset
Yes, we all can confirm this. And it seems to be an grounding problem.
Are HTC going to resolve this or are we stuck with the problem?
Now i've just got the trackball issue, both these problems seem to be hardware related and would be impossible to resolve in any future firmware updates
if these problems are proved to be a hardware defect that is apparent in every htc hero handset are we entitled to terminate the contract? sorry, not really up on my consumer law
thanks

Regarding the screen issue, I think you'll find this is more to do with the nature of capacitive screens, rather than a fault per se.

Dave
hmmm, iphone doesn't have this issue?
iPhone has a metal trim around the screen... and guess what, you hold the handset by gripping the metal trim around the screen
As per my original post if you lay it on a table without holding it the iPhone is fine whereas the hero is unresponsive
Depending on how you use it, it may help knowing that the problem is not present when you have it plugged in for USB/charging.
HTC would probably argue that being a handset, it is designed to work best in the hand...
It does work really well when operated single handed. At least that's my experience.

being plugged into the usb will 'ground' the device anyway. designed to work best in the hand.... and... not to work when placed on a table???
When I hold the phone and type using one hand i dont always touch the metal frame on the front, which becomes frustrating when keys you know youve pressed dont respond, maybe somebody will bring out a metal back casing - i'm sure that would solve it
The problem must be more subtle/complex than that. I know the issue you refer to, get the same problem when placed on a desk. But I don't have the issue at all, single handed.
But, I'm using it with a rubber (gel) case. So I'm not touching anything metal. Hence, I don't think it is just a case of touching metal.
I suggest you have a go with a glove on, probably find the same...
Zuber
How come magics and dreams don't have this problem?
They are not capacitive, so not really comparable. Hence references to the iPhone.

I've just tested this by suspending the phone with string and i can confirm that the device definately needs to be grounded for the keyboards outer keys to work properly.

Agreed, I also have a gel case and my other hand never touches the metal surround. I don't really see a difference if I hold it or not.

The Dream (aka G1) has in fact a capacitive screen and did not exhibit the problem with unresponsive screen edges.
The propblem is apparently specific to Hero. Is this fixed in later hardware revisions of the Hero? I might be tempted to send my phone in for an exchange...
im on my 4th handset within a 3 week period, apparently all different batches, and they all show the same symptoms

typing through a waterproof camera case?

Is it possible to type with a capacitive display also through a waterproof camera case (it's like a clear slim plastic bag; it means no direct contact with skin); I use this for hiking/biking as a rain protection for the device.

I'm afraid not mate. As far as I'm aware, capacitive screens require the small electric charge that we naturally give off, and the plastic cover will stop conductivity.
If that's a deciding factor for you getting this phone, I wouldn't recommend it. Maybe see if there's anything around that does the same job, and works for capacitive screens. I don't think it's impossible, as you can get screen protectors that work (as seen on iPhones and soon on my HD2).

Don't have HD2 at the moment but do have an Iphone. I modified a transparent pencil case which I use on motor bike and bicycle - no problem at all typing on the Iphone capacitive screen.

You're not as wrong as you think.
It's true that capacitive screens work by measuring a distortion of a localised electrical field, caused by the small electrical current given off by human skin but it doesn't mean that the screens cannot be covered at all - there are plenty of screen protectors on the market that work just fine with capacitive screens.
But if there's too big an obstruction, it will interfere with the usage of the handset, such as wearing gloves etc.
Mine seems to work ok in this one - the Ortlieb GPS case.

Thank you for your information. Great that it works!
got a waterproof beach-case for electronic devices for storage, can try with that later today
I use a Run.gps armband with my HD2.
Screen works fine !
I use it for cycling to work everyday
it was designed HD/Iphone sized devices, so the HD2 is a bit tighter fit, and the headphone hole is in the wrong place in the neoprene (but that was easily fixed )

Can a Magnet Harm a Nexus One

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
JAW$
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.
