Repairing S pen - Galaxy Note GT-N7000 General

This is my first post here and I hope to make it a good one which someone somewhere will find useful.
Basicly I had my Note for just 1 day before the stylus started acting up, the screen would sense the stylus upto about 8mm away from the screen, very irritating! I actually found a video online about how to combat the problem by wrapping foil around the pen to block the signal, while this may work for some its very tempermental and doesnt allow the pen to work as its designed.
I dismantled my pen, mole grips adjusted correctly with some cloth on the jaws to stop any scratches and the end popped out easily enough, once thats out press the nib on a hard surface so the button raises and prise it out with a pin and then everything will just slide out from the back.

once apart i was faced with these components plus a tiny mangled piece of rubber, i assume it was a o-ring between the magnet and the coil to stop them from touching, after some testing with the pen apart it was quite clear to me that I needed something to replace the o-ring.
First I pulled the coil off and found there is an o-ring under there, i glued the coil on with silicone gasket sealant to repace the o-ring so I could use it to replace the broken one, however this didnt go to plan as the o-ring wasnt thick enough, all wasnt lost as the silicone gasket sealant was doing a better job of mounting the coil than the o-ring was so I left it in place.
I began a quick search for something else to give some resistance yet still allow the magnet to touch the coil when the nib was pressed down, i tried many things but they all failed and made it very hard to get the screen to pickup the stylus, eventually I pulled some cotton from an ear bud only a very small amount is needed and make sure you don't squish it or roll it up, leave it fluffy and wide enough so it cant fall out of place, yet thin enough so the magnet can touch the coil when pressure is applied, experiment with different amounts I managed to get it perfect on my third try.
When the time comes to reassemble I decided to glue my magnet to the nib, partially because it made it a hell of alot easier to assemble but mostly because im sure the magnet fell out of position and this was what destroyed the o-ring in the first place, Id advise against using superglue to put the cap back on as it tends to dry when youve only pushed the cap half way down.
After you're done go an enjoy your working s pen again, as you can see I edited all the photos using my modded s pen without any hassle, i'll update the thread if it ever stops working again.
And yes the pressure sensitivity is still working!
What you do with your stylus is down to you, if you choose to follow my guide you accept all resposibility for anything that happens as a result.

Does your G1 screen have any "flex" with the screen open?

Hi,
New G1 today - With the screen slid open it feels almost loose (Eg, I can wiggle the screen about backwards and forwards [NOT slide it back into device]).
I do not find this problem when the G1 is in its PDair case however this is most probably because the leather strap that goes around the top of the phone removes any slack that it seems the G1 has.
I do not really want to return the phone as this is my 3rd handset (First 2 were faulty) and would be able to cope for it if this is a known thing that many have however if this is a significant problem I'd have no option...
Look forward to hearing from you.
Cheers.
My Dev phone has a fair amount of flex. I thought about trying to take it apart and tighten it up, but I think I'll let it get a little wear and tear before I go messing around with it like that. The only thing I am really worried about is if I ever drop it with the screen open which could result in it snapping all the way off, but in normal usage it isn't too terribly bad.

It's normal and due to the relatively weak construction of the sliding arm design. Basically the entire screen swings and is held in place on all axes by one thin metal arm.

Thanks for such brilliant replies - The photo inparticular is very interesting.
Only thing is reading back my description I'm not sure if I was clear.
Imagine holding the keyboard still and lifting the screen into and out of the photo... The screen has some give or flex in this axis.
Even now I'm not sure I've explained it well... Can you please confirm you understood correctly before and this behaviour is normal for a G1?
Thanks!
Basically there is no axis that the screen does not have a bit of give in, if you give enough force. Of course if the screen is just flopping around loose then that's probably a defect. But it's normal to be able to lift the screen away from the rest of the body when the screen is closed. Hopefully the next iteration will have a more robust design that attaches with atleast two points on the main body.
My above issue is when the screen is open (As in fully slid out)... I wouldn't say it is completely floppy but requires very little force to move. I don't mind if this is a design "flaw" but want to know so that I know if I need to return my G1 or not.
Thank you very much for all of your help - If you could confirm regarding my issue being when the screen is open (Fully slid out) that would be great.
Thanks again!
yea this is happening to me too, and i know its not normal bc my phones brand new and it didnt do this until the other day, and my other friends phones dont do it either
Not that this is what you want to hear....
I'd get another one.
HTC needs to get their crappy work back. I mean, I love what they do, but they don't exactly prioritize doing it well. If we keep sucking it up, they'll keep doing crappy work.
I'd say unless the screen unit is moving 1.0+ millimeters away from the casing then forget about exchanging. Some devices have looser screens than others. If your device has play in the lower left corner more than a millimeter then it is beyond the average. However, you should keep in mind that you might get a refurb in return and it could be worse or have other defects.

G1 Slide action detector failed

Right, so.
This morning a tiny (5x7x1mm) black sticky backed magnet was stuck in my g1 hinge, there by stopping the slide motion and furthermore leaving the screen stuck in landscape mode, i prodded it and it feel out.
So, I rang T-mobile, and low and behold as my G1 has a scratch on a corner it will be deemed as having been dropped. and therefore they wont replace or repair it.
Ok, so...
Ethire, where in the phone is the magnet meant to go. So I can replace it.
Or, will HTC throw a wobbly because my phone has JFv1.41 rom, or because of the nick on the corner.
Idea's please?
You got insurance on the phone?
no, I assume as now I've asked them about it if i take out an insurance policy and then claim in a while it wouldn't go so well....
unless its something else...
Well your other solution would be just to unroot it and send it back to HTC to get repaired. I would do it soon the phone is still under a year old.

Right, In this image inside the slider hinge section there's a small recess with a white Square in it. That's where the magnet came from....
With the screen half slid out (like in the image) it should be possible with some cleaning and a tiny amount of glue, to replace the magnet in place..
hello. did you fix this? i have same problem but i dont have tiny magnet
I just opened my screen and placed a small magnet on the keyboard to the right of the enter key and my screen flipped back to portrait because it thought the screen was closed. Try this and see if it works.
the jokes I can play on my wife using a magnet now. MUHAHAHA
try a screwdriver with a magnet tip

Welcome back. Its been slow since lunch time.
OK! PROBLEM SOLVED! I founf excellent magnet in Notebook HDD. It was 1mm high. (excellent) and i can broke it east that i can make about 7x5x1mm magnet then i use glue and everythings work
got the magnet but slide sensor doesn't work
Hey guys,
My G1 got crashed (my wife left it on the roof of her car) so I had to replace the screen. It went smoothly but now it wouldn't recognize when the keyboard is open. I have the magnet in place so I guess it's the sensor part that got screwed up. Any ideas how to fix that?
The biggest problem is that I did a hard reset and it wouldn't let me set up the google user name and password because it is waiting for the keyboard to be open. Any workaround for that?
Thanks,
Tamas

The hole next to the Flash...FACTS!

I found out today after taking apart my DHD's (one is north american ATT the other is from softbank Japan). The hole IS NOT just for easy access to the cover, there is in FACT a second microphone for noise cancellation, I know this was a hot topic in the past and it is true. I know because one of my phones has it and the other does not. In fact i've been told numerus times that people can hear alot of wind noise with my Softbank DHD, I never had this problem with my ATT handset.
As you can see the little black box is missing form my Japanese Phone, at the bottom of that is a small microphone

Sh*t,my sim-free DHD doesn't have it...Oh well,I'll survive!
Nice find though man!Well done!
I don't have one either However, no one has complained of background noises when I call them.
How do you remove that cover? Mine is always bulging out.
Nice find.
My DHD doesn't have this second mic and my girlfriend is always complaining of background noise when it's windy outside.
I have it <3
That's actually a really cool feature, I am glad to see HTC putting something as simple as that in, that I am sure would actually have some effectiveness without adding much cost.

If you have the hole its as simple as inserting a pin and turning towards the left until the cover pops. DO NOT turn toward the right or you WILL snap the cover.
If you DONT have the hole, its a lot more difficult (I scratched my phone) but you need a VERY thin flat head screwdriver to insert into the right side of the cover and ply SLIGHTLY to get a little space *jewlers would work great* then get something larger so you dont bend the cover, pry SLOWLY until the cover pops off.
WARNING: I find this very difficult to do without scratching your phone.
PS. The reason I pulled my cover was to clean the gps contacts and bend them upward for better contact. It worked great for me so if you take your off, do yourself a favor and do this.
On one of the disassembly videos, they used a tool from inside the battery slot to push it off from inside, I certainly wouldn't attempt to remove it without a very good reason.
do you think it is possible to identify the part and retro-fit one?

Fix for Sleep Of Death!

Did your tablet screen go out? Does the backlight still come on, but the screen shows nothing? Can you hook it up to a TV, and the picture comes out fine? If so, it is most likely a loose cable, and can quickly be fixed by you, without RMAing it and waiting weeks or months. While the guide should be spot on, and you aren't going to be harming the device in any way, I'm still not assuming any responsibility if you destroy your tablet. You will first need to take apart your transformer. There are plenty of guides out there, so once you get the back off, come back here!

Hi stuntdouble,
Two torx screws have to come off first, these are part of what holds the bezel down.
After that you need to use a guitar pick from the back to lift the bezel up...best to get all 4 corners up and keep sliding..as soon as it wont slide lift it out and back in again a bit further on... it absolutely destroyed the pick by the way..lots of sharp edges in there.
The bezel will then come off from the front of the tablet. Just be careful and dont force it, Around the 40 pin connector was the biggest pain.
The back cover is held down by 4 screws on the top glass, and umm if I recall about 10 screws behind where the bezel . It basically then falls off once all screws are off with not to much effort.
There are also no security stickers over any of the screws anywhere inside the tablet

Take a look at the bottom, you should see a strip with a bunch of multicolored wires coming from the battery. Underneath it, and near the bottom of the battery you should see a ribbon cable. Here's a picture, the display cable has a flashlight shining on it.

Try pushing that into the slot a bit and see if that fixed it. If not try pushing on a few of the other cables, if this doesn't fix it, then I would suggest you RMA it, although I really think this will fix it for you. This has happened twice to me, and each time, pushing cables a bit seems to do the job.
Best of luck on fixing it and post your results please!

Droid X Wifi Antenna FIX with pics

If anyone out there still uses a Droid X...
This problem has been driving me crazy for a long time. My DX would only have wifi reception with a case on or by pressing on the case in certain areas. I've looked all over the web trying to find an explanation or fix, but no one seemed to know for sure what the problem was. I disassembled and reassembled the DX a few times, each time taping over a contact pin until pressing on the case no longer fixed wifi reception, thus narrowing down where exactly the problem was.
It turns out at the top right of phone (when looking at the screen) there is a small pressure pin on the motherboard and a copper pad with a small flex on the back case (the part you remove to access the board). This flex disappears into the side of the case, which I assumed to be the antenna. If you're looking at the inside of the back case, you'll see three contact pads for the camera flash and just outside of that is another copper pad. This is the wifi antenna. On the motherboard you'll see three spring pins for contacting the camera flash pads, and a small spring pin outside of that. This is the wifi contact pin.
The problem is that as the case wears out and spreads, the spring pin on the motherboard no longer makes contact with the copper wifi pad. Only by squeezing the case will they make contact.
THE SOLUTION: I added a small solder dot to the copper wifi pad to add a little height, being VERY CAREFUL not to overheat the board or flex! It is very easy to cook a small PCB and flex like this and burn through the board. If you're not comfortable with soldering (I solder flexes at work all the time), you can try to add a copper shim on top of the pad on the case to increase the thickness. You can also try to pop the PCB off the case and add a shim underneath it, but that little PCB seemed to be on there pretty tight. I wouldn't mess with the spring pin, if you break it off the motherboard you're pretty much screwed.
And now for the pics:

Nice job. :good:
Luckily I haven't had to tear mine apart yet. Small solder jobs can be tricky. I've had to solder and or reflow a bunch of first gen xbox 360s and everyone was a pita.
Nice ... I love hard ware hacks.
This totally worked! I just soldered my Droid X per instructions and now my Wi-fi connection is surging like I've never seen it do (got the phone not to long ago as a hand-me-down). Before if not in the same room as the wireless router I barely even get a signal, now I'm able to detect signals from all around the neighborhood. Great advice! Thank you!
Cool fix
