Battery question: Anyone experienced this? - Touch Diamond, MDA Compact IV General

My stylus does not "snap" back in to the side of the phone any more. The magnet in the battery is very weak. Does this mean I need a new battery?
Thanks

there is no magnet in your battery the pen has magnet tho.

So get a new pen? How the pen lose the magnet strength?

try to put the pen sideways into your comps case or other metallic objects and you'll see if the problem is your pen (and there is extra pen the diamond box)

Maybe your pen has changed his magnetical orientation. Try the other pen, then try if your pen is still magnetic. If it´s still magnetic try to change the magnetic orientation with another magnet. If both pens are still magnetic but don´t stick in the hole maybe the metallic counterpart in the diamond is misplaced (already happend to some Diamond users). Then remove the battery and try to locate it, maybe you can fix it.

Thanks, the magnet in the pen is still strong, but only half the pen.
Fault with the phone? I have not dropped it.
Sorry for my newbie questions.

problematic stylus

hmm... my gf's 1 week old TD has started to 'self-eject' the stylus automatically... doesn't get 'sucked' in anymore, the magnet is still working when i place the stylus on the batt cover but inserting it back into the slot face the same issue... the stylus is tilted at another angle instead
should pay HTC care a visit?
she's really pissed to get something 'high-tech' for once plus i was the one to 'psycho' her into trying ppc
anyone else face this at all?
No problems here with the stylus, so I guess it's best to give HTC a call and let them fix it.
And oh well, if it makes your gf feel any better: A magnet is hardly hightech, especially considering it's probably just glue'ed in there. So it's the 'lowtech' thingy that's broken, not the hightech
yeh, i probably should...
this phone's given me some fun exploring a new model(i'm using trinity btw) but also given me more problems....
should stop inducting ppl around me into the dark ppc world... crossing over to the dark side just creates more lights to be put up(by me btw)...

lol! friendly advice ! danger! "pissed girl friend" means trouble even if it's because the pen is not "sucked in". lol!
on a serious note i tried to magnetize the pen (i wasn't satisfied with the way it was sucked in ) with the magnet from my htc athena only to get the opposite effect. don't know what made me think that the pen is the magnet and not the diamond. well, experimenting...experimenting
maybe you or your girl friend have the pen near a magnet? a not too plausible scenario ...
i thought so too bout the magnet, i actually chided her for putting/leaving her phone somewhere that has a strong magnetic field...
she adamantly insisted "NO!"... ok, time to zip.
shall pay a visit to the local HTC care centre...
That has something to do with the orientiation of the magnetic field. If you place two magnets together facing with the north and south pole together they will attract each other and with north facing north.....ok I think you got the magnetic basics.
This could only have two reasons, your pen got magnetized and now he is pushed away by the magnet inside the diamond. Or the magnet inside the diamond got misplaced and he is now facing with the wrong side towards the pen.
Try if your pen is magnetized maybe with a paper-clip. If so try to change his magnetic orientation with another magnet by moving it over the pen in different ways as you were sharpening a knife.
hmm.... should give that a try... thanks for the suggestion
was pretty bout the magnet used when reading bout this new model, thought that might cause some problems(yes, it had to be me unfortunately)
pen is the magnet, so magnetise it.
just done to mine, it now flys in
I experienced the same problem today... but I don't know how it happened. I think the pen now has the wrong magnetic polarity. The magnet inside the cover doesn't like my pen anymore
So I will try repolarise the pen with a magnet.
The magnet is inside the Diamond next to the Battery in the Area where the Stylus slides in.
There is a little Magnet in the Stylus as well.
If the Stylus does not get sucked in, the Magnet inside the Diamond, next to the battery, is probably misplaced. This happens if you put the stylus on the right hand side of the Diamond, just about the middle. The magnet gets pulled out of its place and the trouble starts.
dont you have another Stylus? there were 2 with my diamond...

Stylus not springing in any more...

Hi all,
Not quite sure how to explain this. When the Diamond was new the styles 'sprung' back into place with its magnet. Now, I have to push it in - it defaintely has some resistance. I've taken the back off and cleaned it but no change.
Anyone else got/had this?
Rich
the magnet beside the battery has probably gotten unstuck.
several ppl have had this same prob; I was the first, I believe.
just need to get a tweazer and some glue to hold the magnet in place.
i thought it is the stylus that is magnetic not the pda itself?
Hi,
Thanks for that - I can see a magnet on the side of the batt (cirlced in the pic below) but it *appears* to be ok. Does it look fine - or has it moved - or has something dropped off???
Rich
ok ok - fixed it. The magnet had come out of its whole and stuck to the side of the battery. By replacing it all is ok now. Thankfully I did not lose the magnet!!!

Well done...

The stylus is the magnet not the pin inside die Diamond!!!
Try to hold your stylus against some metal...
horstborsch is right. the stylus is the magnet.
the stylus attracts other metallic objects, not the phone.
what we see in the image probably is the switch that detects the magnet
I have tried to fiddle around with the stylus and the phone, in order to solve this little "mystery" and I think that they are magnets both in the phone and the stylus.
This will make the stylus lock in place. The phone has a magnet where the north is up, then the stylus will have a magnet where south is up (magnets are in opposite directions). Therefore it will lock inside the phone, as the south pole of the phone's magnet will attract the north pole of the stylus, and the opposite for the other poles.
If the stylus won't lock properly in place, one reason could be that the magnic field of the stylus has been disturbed or changed.
Fx when you place the stylus on top of a speaker or any electrical component having a magnetic field.
However if it is a good magnet this shouldn't affect it, but you never know..
The stylus can be completly demagnetised if you pass it through a solenoid, but I don't think anyone tried that yet with the stylus
I'm not saying that I'm right, but at least it could be one solution
Cheers!
Hey guys, I have also just found a little magnet. But I have the MDA Compact 4. Could anyone point out where I need to put this magnet back?
I have tried putting it in various places but it does not work.
Thanks guys.

Doe your metal battery panel sit flush with the cellphone?

Hi guys
just a quick question about the back of the captivates. When trying to lock in the metal battery cover, my metal cover does not sit flush with the back of the phone, the metal cover sticks out and I need apply pressure to press it down in order to slide up the plastic locking piece. Kinda curious if thats the case with all of the cappys or just mine? THANKS!
How much pressure? I have to kinda push it down but not hard at all, just kinda seat it in there.
when mine rests, its just a couple milimeters out... So yeah, i have to push it in to close it. But its not a considerable amount of pressure, its something a toddler could do . Once its closed though, its nice and snug

Agreed. It's supposed to take a little pressure to open it. If you're just talking about the aesthetic of the phone, I, personally, like the way it looks recessed. I like the metal back enough I hate to use a case that covers it.
I think it's designed to stick up a little for 2 reasons when unlocked.
1. it makes removing the back over a little easier since it is raised and you can place something under it to lift it out (typically your finger)
2. to apply pressure to the latch so it is not lose and does not rattle or make similar noises that bug/worry ppl.
It might also be a side effect to one of the connectors that ground the back cover, as the one on the left side is a pin with a spring underneath it.

[Q] Why magnet may affect SGN and not iPad2?

I will be buying a case for the SGN which will have a magnet. I have read some of the posts here about possible effect of magnet on the SGN, and seems many people concluded that magnet should be avoided if possible, and my common sense agrees with that.
However, I am quite puzzled why Apple has used strong magnets extensively in their iPad2 and that the device is not being affected. It actually has magnets on the left and right side of the device, as well as the smart cover. Any suggestions?
BTW, this is not a post about Android vs Apple, just a general question about effect of magnet on devices.
Won't it just be the fact that the ipad is miles bigger, so probably more space between magnets.
Maybe because the magnetometer inside...

It is probably because the SGN has a magnetometer inside, a very sensitive instrument for measuring magnetic strength. I dont know anything about iPad, but this is my guess to why a magnet would affect a SGN negatively
http://en.wikipedia.org/wiki/Magnetometer
I thought it was because the Wacom touchscreen/stylus technology in the Note is magnetic, while iPad touchscreen technology is capacitive, like most other devices these days. I don't think a magnet would cause any damage, just screen interactions/presses. Someone correct me if I'm wrong.

You are probably right. Sounds more plausible than what I thought
The wacom digitizing technology is not exactly magnetic as far as I know. It is actually that your S-Pen has an electromagnetic coil inside it that communicates with the digitizer in the screen. This electromagnetic coil can be affected by a magnet in the vicinity.
In the case of ipads, ipods, etc. they all have dumb styluses, so a magnet does nothing to them. At the same time, because your spen is actually more than a stylus - it doesn't work on normal touchscreens (go ahead and try it on your ipad ).
Edit: I just checked, the SPen uses a technology called ElectroMagnetic Resonance. There's a capacitative coil inside your Spen that receives signals from the digitizer in the screen when the tip is pressed. The mesh of the digitizer provides power to the Spen through resonant coupling, thus enabling it to both receive from and transmit information to the screen.
So in conclusion, the magnet is not damaging our device, just confuse the spen and it's precision.
So it is safe to use case with magnet mechanism, but when we take off the device from the case, all is OK.
Don't a lot of docks use magnets to signal that the phone is docked? For instance, when I put a magnet up to my Droid X it will either think it is in a home dock, or a car dock, depending on its polarity.
but they do not have s-pen technology inside them
safe to say, i think it's ok to use cases with magnets caveat emptor when you're using the s-pen
I don't know what effect a magnet might have on the digitizer inside the screen, so please check with samsung customer support first...
The part that concerns me is that samsung make it sound like the issue is 'long term exposure'. I suspect that it might screw with the calibration of the magnetometer over time.
If it was just an issue where magnets would make your s-pen act screwy in the short term they would've surely just written 'magnets may make your s-pen act screwy'.

Galaxy Note II Case with Stand Photo Review

Hi initial photo review of this case. Will write a full review later tonight.
In a nutshell it is well made and light. Fits very well in trouser pocket. Does not feel bulky.
Price about £10.
You will find them on ebay in various colours.
If these photos help you decide. Feel free to hit the old Thanks button.
Glad to be of service.
That case looks great. I love how it protects the edged of the phone, unlike the official Samsung flip case. Does the flap stay closed using magnets?

Thanks for the pics. A link or two to the ebay sellers would be nice, though...
Edit: Is this the same seller?
Also, does the magnet cause any issues with the s-pen?
Tried one out and found that I had to take the back cover off to fit the phone snugly.
Since the cover doesn't have an NFC chip, you will lose that functionality. The case doesn't fit on the phone with the back cover on unless the one I saw was a duplicate. Moreover the magnetic closure is flimsy too.
Just my 2 cents.

The NFC antenna is embedded in the Note 2's back cover.
For the record. The handset clicked into case. Nothing had to be removed. Grips it fine. Must be a different case if you have to remove covers.
So far only really annoying thing is using it one handed. The folding cover is in the way of fingers.
There is a similar case that has a rotating cover. That would resolve this issue. Also enables a portrait stand.
Also as suspected. The home button is being pressed by the cover due to no recess (think thats the correct word) in the cover. This is activating the voice assistant. Disabled it as it is rubbish. But will mod cover at later date.

Another little update, these stand cases are really good for watching iplayer etc. But I think I am going to buy a leather sleeve/pouch type case. Ive always used them with htc handsets, due to most usage is one handed. And save the stand case for movie time.

I bought the Original Samsung Note 2 flip case instead. Although it was expensive £30 .... but I think it looks really nice and still have NFC function.

The biggest flaw with the original Note 2 flip case is that the corners/edges are completely unprotected. If you drop the Note 2 and it lands on the corner it might shatter the whole screen.
Not enough protection for my taste...
I bought this case yesterday in a shop and was massively disappointed. If you fold the cover behind the phone to use it the phone is hard to handle and doesn't sit ergonomically in your hand.
BUT BIGGEST FLAW: The little magnet on the right side interferes with the wacom digitizer. Try pulling out the S Pen and draw a straight line along the right edge, and the line curves outward around the magnet.
I was about to return the phone when I realized the error was next to the magnet. Pulled it out of the case and problem gone. I could reproduce this problem anywhere on the screen by holding the magnet part next to it.
There are tons of reports if you google "wacom magnet s pen" about interference, so I would avoid using this case. There is apparently even a note about this in the manual somewhere.

This happens because wacom digitizers use magnets to work (partially, there's more to it) - the pen is a magnet. Crash course: A magnet creates a magnetic field around it. Whenever you're moving the pen, you're moving this field - any given point in space near the magnet experiences a change in this magnetic field (this creates an electric potential and a potential difference between points affected by the field). A really cool thing about moving magnets near wires is we create what's called an induced EMF - the change in magnetic fields causes electrons to move because of changes in relative potential difference between nearby points.
A static magnet (in relation to a point) will have a static field, but a field none the less - the magnet on the casing. When you bring two magnetic fields together, they interact to form a resultant field at any point in time.
The pen is still working as intended, but the other magnet has changed the potential you produce near that magnet via movements of the pen - thus, different and incorrect readings. It's relative to the position of the case magnet, so you get a different effect at different distances from the magnetic source.
The result is that the same motions of the pen near that magnet are causing different currents to be read than the wacom digitizer expects for that motion.
While it's great to hear through some empirical data that physics still works, I was already actively avoiding this case for this reason.
In contrast, previous smartphone cases with phones that use capacitive touch don't have as much an issue because it's basically a field of current that your touch (finger, capacitive stylus, etc) redirects some of that flow across. While a magnet could indeed affect this field, the magnet isn't moving so it's not as much an issue (it's still an issue because, depending on field strength, orientation, and relative locations, the electrons are still moving with respect to the magnet, and are repelled/attracted by the field in this manner to different degrees. However, the difference is constant and like is accounted for because digitizer system can't guarantee constant currents necessarily, so there is variation allowed for. With the Wacom pen magnet, it's weak enough to be noticeable.
TL;DR - Anyone with a course in EMF and an understanding of induction would be able to tell you this right off once they found out the pen uses a magnet. Incidentally, the magnet is also why you can do the hovering stuff so accurately. Other forms of non-touch gestures have many ways they could work too, but one way is your body affecting a field around the digitizer enough (whole hand swipe across without touching) that is is measurable.
It's also how inductive chargers (ones where you don't plug in the device) work. Changes in current flowing through wires creates a magnetic filed which, by orientating the wires, using loop/solenoid type configurations, this field changes (an AC signal). When your device is in the field, a similar configuration in the device is subjected to this changing field, and, more simply put, energy is exchanged via magnetic fields.
This is really cool because you've taken a changing current, which creates an electromagnetic field across other wires, which causes a flow of current.
Anyways, yeah avoid having magnets near devices depending upon EMF induction to work
In response. Regarding the case and holding it. I agree, does my head in sometimes. Hence why i may get a sleeve instead for when at work and use it one handedly most of the time. Regarding nfc, i aint convinced it would be affected until i get to test it. Regarding magnet, never noticed it until tested. Only effects 5mm of right side of screen and 15mm vertically, not the end of the world.
Just tested a piece of tin foil placed between handset and case at the point of the magnet. Didn't make any difference. Shame it cant be shielded.
Gotta say. The mobli is very well protected and the white case and mobile has yet to look dirty. Day job, hands get mucky.
Anyone got the case that the stand rotates? Does it make holding it less annoying?

So, can the magnet cause any permanent damage to the gyroscope, compass and wacom bundle? I did notice that the compass is off by 10 degrees with the case on versus off.
I've used the phone for a few days without the case and it gets greasy too fast. So its back into the case again. It is pretty sturdy, just wonder if its possible to extract the magnet somehow! Maybe lodge a knife in there or something.
Anything that works by sensing the Earth's magnetic field, such as a compass, will be screwed up by a magnet in a case. It's really not worth buying a case that has a magnetic clasp...
I lodged a kitchen knife in between the magnet and the case and jerked around. It broke up into several pieces and came out attached to the knife. Since its either in my pocket or on a table the flap stays closed and no more magnetic issues.

don't be so harsh.
