So my Epic 4g touch has a fried microphone.
I am not new on opening up phones, replacing flex cables, or lcd screens etc because it is very simple. But now this requires soldering and all that from the motherboard.
That is what I need help with, I do not just want to jump on it right away... I do not even know where the microphone is honestly.
Also to kill two birds with one stone, I need to do the same for the USB Port.
Why not just buy a epic touch with a broken LCD and make one phone out of two. Ribbon cables are one thing but soldering a tiny phone.. I have some experience soldering but I would have to feel pretty brave to do it on a phone.

I thought about that too but these prices are ridiculous. Literally a destroyed phone which looked like someone torched it with a flamethrower on ebay went up to $120. The seller claimed nothing could be tested and had bad ESN.
I'm not good at gambling.

Good news is I found the microphone. It's on the bottom on the back side of the motherboard... And it's really really tiny

im too lazy to take mine apart to look at the motherboard right now, however looking at the pictures of the motherboard on ifixit it looks like there are only two traces running to it, and its surface mount...not sure how you would go about lifting it, as i'm assuming the amount of heat required to do so, even using a proper re-flow station (dont think a heatgun will work for this one! its a little smaller than an xbox 360 mainboard!) would negativity affect/destroy the microphone itself...furthermore I'm not at all sure how you would go about sourcing a replacement microphone... I can't imagine Samsung would be able to send you one... now that I mention samsung though, these things have a one year warranty, you may want to contact them and ask about getting it serviced from them... I know some people with emmc bricks have had success with getting repair work done directly by samsung.
the usb port is easier though, de-solder the 4 posts holding it in place, and then very carefully using your iron and something like an xacto knife very carefully lift the pins connecting it to the motherboard... scavenge a similar one from a suitable donor device, solder the posts into place and then just use your iron lightly to push the pins back into the solder left on the pads... I've not done a micro usb before but have successfully replaced several hdmi ports using this method, same thing, only smaller with fewer pins... good luck with it...

Thanks for the tip!
Unfortunately I have no insurance, but the way I see it is that if these guys can do it http://cellphone-repair-shop.com/samsung-microphone/ then I should be able to do it. (I really wanna do it as well not only to just fix it but to also learn something new if you understand). Also, I can use the same microphone from an AT&T Captivate which I found for $9.99 on ebay. Tomorrow I will post a picture of the motherboard and the location of the microphone.
newalker91 said:
In order to do it you'll need to use a precision heat gun to warm up the microphone, then use something like a razor blade to pop it off of the board. Regular soldering irons aren't used for this type of placement, you'll have to cold solder it in place making sure to get a good solder joint around the edge to keep it lined up perfectly with the contact points on the board.

Interesting. So you're telling me I can't use de-soldering wire...
Then wouldn't it be the same to heat up the razor and pop it up? Sounds barbaric but that was the first thing that popped in my head after I read your post.
And since the mic hardly has any electricity that runs through it and is so tiny would it be better to use that carbon based electrical glue?

Oh I totally understand why you would want to do it yourself, I had thoughts on how to do it because I do the same sort of stuff whenever possible... I think the guy that posted afterme/you had some really good thoughts as well, only thing I wanted to add is that I was not referring to any sort of insurance, but to the 1 year Samsung manufactures warranty on the parts

The one circled in blue is the earpiece sound receiver I assume since it is connected to the earpiece or could be a secondary mic for the camcorder although this phone is not known to have two mics. Regardless of the fact, it remains irrelevant just wanted to point it out
The one circled red I am sure is the microphone since it is located right on the bottom where the mic hole on the phone housing is on.
As you can see it is pretty tiny. Any ideas?

CAUTION: IM NOT RESPONSIBLE FOR MESSING UP YOUR DOCK OR PHONE, DO AT YOUR OWN RISK...
ok on to the mod. I did this mod to the OEM dock because I think it was a dumb choice to use the usb plug when you have the 3-pins, plus the usb will damage your phone when trying to fight the phone in to place...
so here are the pics:

information:
buy: glue, battery pins...
remove the rubbery buttom its held by double sided tape, then remove 4-screws..
then you will get to the board.. its held down by 3-screws
then you can either, remove the wires and solder you it back or u can cut it.. you basically need positive and negative wires since the pins doesn't transfer data through it...
now to the top part.. it is all held in buy glue but its still built really well.. I opened it by prying at the top corner... you will find out that that is the best spot to start to open the dock with minimal cosmetic damage...
then you just work your way around the seems untill it opens up
once open this is what you see... careful not to lose the white plug... now you can take the usb plug and cut it, since its no longer useful...
now the hard part is to try and get the holes aligned right....
once aligned, glue the battery pins and solder... black is ground, green connected to black wire, and red is positive.. (yes i need more soldering practice )
and finally...
click for vid...
any questions let me know....
thanks for looking
Wow. Bravo.
This is how the dock should have been in the first place. Excellent Work OP. By the way. Where did you get the dock pins from?
Just brilliant
Very cool, might be a good weekend project!
Just wish the base dock wasn't so much money :/
Does it charge any faster using the pins rather than USB?
Do you have the part number(s) of the charging pins and where you got them from?
Also, it looks like you have a couple of different sizes.

It still shows charging status as usb, trying to figure out how to chance it to ac instead...

Great job OP, much better then stock POS they're trying to sell for $50.
Couple of quick questions:
Does bluetooth turn on automatically when you put in the dock?
Is 3.5mm headphone jack covered or can audio-out cable be still plugged in?
At what price point would it be profitable for you to start taking orders for these?

I didn't want to clog/hijack THIS THREAD but the pin info and idea was very helpful. After waiting and waiting and waiting for official word of a charging dock that utilizes the pogo pins on the side, I've given up hope. And lets face it if you kill the usb port on this thing "you're screwed". so I really wanted to reduce my usb port usage and utilize a feature that comes with the device.

My material list is 8 screws, 46 gauge guitar string, a strip of 1/2" playwood that happened to be ripped down to 2 1/2" in my garage, usb cable, piece of flat 1/8" thick plastic and a tiny bit of solder. The way that I screwed/bent the piece of guitar string gives the perfect amount of spring so that when the device is set both are compressed and make contact with the side of the device.
This was very spur of the moment and took me a half hour to build. And it works brilliantly. Yes I could have spent more time on design and material type and getting proper pogo pins. But I'm lazy and intent of this thread is spark ideas in other peoples heads. So now this masterpiece lives on my nightstand and I drop my galnex in at night and wake up to a full charge in the morning without having to use the usb port.
**edit** The pic of the lockscreen is in landscape using the Team Kang AOKP rom.
good day.
THIS is what I love to see here. Ingenuity. Looks good to me. I am thinking of putting some docks together here this weekend. One for the nightstand and one for the office.

This is a decent, and probably relevant, read speculating on the function of the third pin on the Nexus One: http://forum.xda-developers.com/showthread.php?t=631508
I love this, but I got some questions I'd like answered before attempting this.
1.For those of us without guitar string, would a paper clip bent into proper shape work well too?
2. What cable is that, that you were using just a power cord or was that usb?
3. You said it just sits on your night stand so does that mean you cant transfer data to your computer?
Also a video just going over it more or perhaps some more pics of the back there would be nice (at least for me) to see what is screwed around the screw.

1. no idea, sorry. Check out the pogo pins though.
2. Thats a power cable, a usb would have a wire for data.
3. the pins don't transfer any information (well... the middle one does, but not anything useful to a pc) so transferring stuff would be impossible. (but thats what wifi is for)
This is beautiful and ugly at the same time.
One thing I would recommend is cutting out an area at the bottom of the phone so that you COULD attach a USB, OTG, or MHL cable if need-be. Perhaps that side of the dock could be shaped like a B, or notched to also allow access to the headphone port.
I would also maybe split out the power connection to a microUSB port to power MHL or other accessories. Or maybe just wire up a fullsize female USB to power another unit such as a bluetooth headset or whatever. It just would be nice to have a powered USB port just in case.
To the guy above, sure it may not look perfect but a coat of paint would spruce it up very well.
Overall A+
I might try my hand at something like this. I'm a cheap ass when it comes to buying crap for phones (since I go through them often). I have all the materials already with the exception of spare guitar strings but the paperclip idea sounds great and can be bent to size. I have some Poplar wood in my basement that would even look good with a heavy clear coat.

I am thinking of attempting this as well. Except I dont have the wood to spare for this, so I am trying to look for a generic stand on ebay that would be possible to modify to fit at the least the pogo pins and at the most everything you mentioned. Because it would be a MHL adapter built in and ready to go.
Nice Job! Very creative use of guitar strings in lieu of pogo pins! I might have to try something like this...

Alright so by demand and as a newcomer gift to XDA, I will show you how to open up the Acer Iconia A100 tablet and how to replace the crappy microphone they provide with it, this thread is going to have pictures and is going to need a bit of organization skills and some soldering skills , so let's start
Before beginning note: make sure to work on a towel or something soft as the tablet will be upside down, I didn't use one and I got pretty bad scratches on my protector, as you will see in the last picture.
BEFORE BEGINNING NOTE #2 YAY!: I am in no way responsible of any damage to your device, your life, your marriage, your emotions, your cream cheese bagel order at Tim Horton's that wasn't discounted 18 cents, or your cat. So do this at your OWN risk.
Before beginning note #3: This will void your warranty....DUH. But I really don't care about mine because my slogan is "I VOID WARRANTIES "
Things you will need:
1) Set of small philips screwdrivers
2) Soldering iron
3) Solder (optional, not necessary as the mics have solder on them already)
4) Something to pry the plastic open with (I used my nail but you can use a flathead screwdriver...etc)
5) Another microphone you are going to use (preferably from a webcam/ headset, as they need to be the exact size or close to the original one)

Now let's get to work.
Acer A100, great tablet, crappy battery and crappy mic.
In the next few images, I will pry off the plastic sides of the tablet, don't worry if you feel like they bend, just run your finger across and under the pieces until you hear all the snap ins snap out.
Bottom side:
Right side:
Top side:
Left side:
Alright, now that all the sides are off, let's get to the screws, there are 5 screws you have to get off, in these pictures you will see where they are.
Bottom side:
Right side:
Top side(NO SCREWS HERE, CARRY ON)
Left side:
Well now I really don't have to say it cause it's really obvious, grab your screw driver and get to work on these screws, make sure you put them on the side after you take em' out.
NOW FOR THE FUN PART , Really opening it up, get your nail ready, or whatever you're going to use for prying the plastic apart, and start SLOWLY prying the 2 pieces apart, CAREFULLY!
And now, completely take off the back cover (Don't worry, there's nothing connected to it, it's just an antenna)
AND BEHOLD, THE INTERNALS! (and that damned battery.....)
Alright now don't get too excited (I learned this the hard way...), there's a few things you must do first, look around and get familiar where everything is, and DISCONNECT THE BATTERY CONNECTOR!(Warning: as soon as you disconnect the battery, the whole tablet will shut down COMPLETELY, so make sure you save anything you haven't saved like game progress etc...then unplug it)
Now the left side is where the good stuff is at, so ignore everything else and just go to the left side.
Notice there is 3 connectors, the Microphone connector (black), some other connector (white and black), and some other connector (yellow), all of these have to go out, and once they are out there are 2 screws holding that small chip down in place, one black and one silver, these 2 have to go out too.
First connector (white and black), just open the small black tab and pull the flat thing out, should be really easy:
Second connector (yellow), this thing just pulls off the board, just easily lift it up:
and now remove the 2 screws and put them aside:
And now really gently pull the small board out, might need some wiggling around but it'll come out, it will be obstructed because the microphone is still in its place, but just lift the microphone out, it slides right out
So I accidentally deleted the rest of this post and lost all the images, but its pretty straight forward, just desolder the microphone, solder a new one on and pop everything back into place, make sure to put the battery connector on last and close up the tablet.
Enjoy your new microphone and hope this wasn't too long, please use the thanks button if it helped you
Man, As soon as I am able to risk opening up my A100 I so want to do this. Thanks, not only for doing it but for taking the time to take pics and post it all. You Rock!
You're very welcome, I had many more pics assembling it back, but I accidentally deleted them and lost all of it haha
Hey do you think this mic might work out? or do you have a part# for the one you used, or from what model webcam you took it?
http://www.ebay.com/itm/Replacement...950292?pt=PDA_Accessories&hash=item4ab6c51954
Well I tested 3 mics from 2 webcams and one headset, the headset was the Xbox live one and it sucked crap, and the 2 Logitech webcams were Logitech V-UM14 and V-UBC40, I settled for the one from the ubc40 as it seemed better than the um14.
About the Nokia one, I don't know if it would work as there are no solder points and you gotta take into consideration the size, both my webcams and the headset and the tablet had mics that were really close in size

Mic Dimensions
Anyone have the Mic dimensions? I'm going to try and order one from Digikey while I perform a screen repair on a friends tablet in the next week or two.
Having the dimensions and what type of connection used will help select the correct one. Is it a surface mount or are wires running to it?
Thanks

My daughter dropped hers on the power plug and the power plug was fouled inside. I was worried I would not be able to replace the power adapter and sure enough, after reading your post with picks I realized I could buy the adapter for $15 and replace it myself. Worked like a champ! Again thanks for the picks, it really answered how to take it apart.
My acer iconia a100 wont charge or power up (maybe because of a one meter fall)
do you think if i remove and reconnect the battery it will boot up ?

Thank you for your reply !
I bought it in november 2011 so the warranty ended
I opened the a100
I remove the battery connector then pushed the power button several times (5 to 30 seconds)
i reconnect the battery & the powersupply to see if it will charge or power on > Didn't worked
so i was desperate, thinking of destroy the **************** tablet but i reassemble it
i retried to power on with the power button.....blue led on...acer a100 is booting
it's working for now, reset the tablet ....wait n see......
This is very interesting, that you would do this, ive contemplated it but ive sooner used a headset when necessery. I have a phone now though. Im gonna loom into revamping the battery. Now thatd be a mod

So is it fairly simple to replace just the battery itself? ie, no soldering for the battery?
Thanks

Yes, I think there are a few screws that hold it down and a plug. So once you open it up it is pretty easy.
Thanks will attempt.

External Mic
Perhaps a silly question, but how difficult would it be to drill a small hole in the plastic near the microphone and solder wires to the mic location? And what would the max length of wire possible? Just rough guesses, I know it's pretty hard to be specific on stuff like that. Reason is that I have mine installed in my car as a head unit and was curious if I could run wire from the tablet to a mic mounted in the roof/headliner so that I could issue voice commands in a normal volume. I'd post a pic of my install but I don't have enough posts.
What could happen if i disconnect the other connectors first instead of the battery connector?
Got it open no problem, using fingernails and an old mastercard.
I do not recommend anyone do this unless they are very familiar with doing similar tasks - there are a number of things that can go wrong and some very delicate connections that will break easily.
Been trying all the PWR, Vol+/- combos and plugging it into my PC via USB. Nothing happens, at all. Is this useful info? No device is seen.
Even tried a dummy SIM to push a small contact switch closed at the bottom of the SIM socket, still no effect.
I've taken some photos, and identified the various antennas if anyone is interested. I will add them shortly.

that topic is full off, warranty crap i would read the s-off development and see if anything is in there.
i opened mine, its quite hard to initially get the screen to pop out, i wouldnt recomend using anything other than finger nails or you will damage something
after you opened it the Power button and Vol button will fall out, dont dop them!
the power button and vol button have a certain orientation, took me ages to realise that the power button only fit one way
removing the mainboard is quite hard, you have to void the warranty and there is a connector that is allmost impossible to get off(next to the battery)
oh and when you pull the mainboard up it gets disconnected from the power button ribbon, so make sure you un-glue the internal power button (pull it up) before pulling up the mainboard
so yeah its hard
Question: What's the pinhole above the headset connector for? Where do you get through that? It's a microphone or not?
Thanx!

It's the second mic, for noise cancellation.

I believe it's also used for the secondary (stereo) audio channel in One X video capture.

Yep, I forgot about that Although going by what some are saying, it doesn't record proper stereo anyway...

Yes, I've seen several reports of that too. Haven't tested myself though, mostly because until the stuttering / dropped frames are fixed, the video capture isn't really useful to me...

That's already been answered before: no. At least, not cheaply. The Gorilla cover glass is bonded in place, so replacing it will realistically involve replacing the entire screen assembly, which is a significant portion of the phone. (And good luck getting a replacement part that's not itself damaged.)
So how easy is it to replace the battery?

Tricky, but possible. The average user would mess it up though. If the connector were located differently, I'd say most could do it. But the connector is on the side of the board facing the screen, so it has to be lifted off to disconnect the battery.
The one major thing that would stop people doing this safely is the small power switch connection under the board that pops off (should be manually disconnected!) when the board is raised more than about 5mm. Assuming the user gets that far and the connector ribbon is not damaged from the pulling, the user then faces the challenge of reconnecting it - and they must or the phone will not power on! It can only be done when the board is almost back in place, using some very small tweezers and quite some skill.
The battery connector itself is relatively easy, but as I mentioned in another post, it comes off differently than you might expect, which leaves room for damage if it is forced. The battery itself is glued down, so must be forced off - again a risk for the inexperienced as you could damage the battery if excessive force is used from the wrong point, or worse, you could damage the delicate ribbon cables that lie under it if you try and pry it off with something by sliding under it.
So in summary: it is possible but only if you have experience with disassembling similar devices and putting them back properly. The margin for error is thin.

Absolutely not. I'm not sure I'd even try that myself without having the proper service manual - there are too many things to go wrong.

You shouldnt have done that...
Lol just kidding!
Is that a connector farther to the top from the pogo pins near the WiFi label you placed? its only one piece but could be our magic lock.
Edit: on zooming in it looks more like a screw.

No, because then people with zero skill will copy it and break their HOX and then blame me. If you can't work it out from the Chinese tear down photos, then you lack the skill needed to avoid doing damage.
Also, I don't have time to make a video anyway

I work in a repair shop, and this phone seems new enough that I couldn't find a teardown anywhere.. so we snapped some quick pictures so people will know what to expect. It is pretty straight forward, not a whole lot can go wrong(for the most part).

Remove the two screws on the bottom, then with guitar picks, your finger nails, or something that won't damage the screen/frame(non metal is ideal) pull the edges of the frame away from the phone- the bottom is most difficult, that is where you have to put in the work.
Also note where the volume and power buttons are, there is flex cable behind there- do not slide tools along inside as you may rip them, just carefully pry the cover from the sides avoiding those as needed.. also remember part of the back is glass(at least that is what I read and it appears to be).
Pull this frame off by removing the screws from the holes that you can obviously see. If I get time later I may circle them in red, but it should be obvious.
Two screws to remove from the mic/speaker at the bottom, then it can be pried off- be careful, but not a lot of risk of damage.
You should be able to see the connectors that were removed to remove the board- as I said, this is a quick walkthru, not a detailed teardown- enough to give the general idea.
This is with the screen removed- basically you heat the front of the screen and the back of the frame to loosen the glue that holds the lcd/digitizer in- there IS glue around the edges of the LCD(and on our replacement) which makes it nearly impossible to remove without breaking.. but you likely wouldn't be removing it unless it is broken. As you can see, there is no special connectors or board on the bottom to light up the digitizer you have to be careful of, so this isn't that difficult.
Here is our replacement screen, there weren't many vendors that had them, but this was found on ebay and appeared to be quality very close to the one removed, enough we couldn't see a difference. Make sure you use plenty of adhesive if it wasn't already applied before you purchased it.
Reverse to put back together- we had 0 issues, the most difficult part is removing the shell without breaking the glass on the back of the phone.
Hopefully this is helpful to someone, or at least will show them it isn't TOO difficult. Feel free to hit the thanks button if it was helpful, if it is appreaciated I may throw a more detailed guide up when we get another in for repair.

great info. a video would be awesome?

I have tried to replace the screen as well. I think the hardest part is to take off the back cover. The place near the power and volume is actually pretty easy to break.

Well, the tech who was doing the work wanted to take his time to make sure nothing was harmed in the process.. now that we see it is like the average teardown, we could definitely do a video on the next one- that was the plan.

Do you mean the power and volume flex cables that are glued to the edges beneath the back cover? We've done so many phones at this point we sort of forget how simple it is to make a mistake there.. I'll note that in the teardown instructions above.
If anyone else has any feedback or suggestions, or want to provide better pictures, let me know and I will gladly update- I just wanted to make sure there was SOMETHING out there for people who may be looking for it..
Since this phone is susceptible to glass cracks on the back due to temperature change (Like the one I purchased), a tutorial on how to replace just the glass on the back would be helpful.
Thanks!

Well i'm part of the replacement group.
Dropped my phone a few days ago, bottom right quarter of the screen has no touch now and a nasty crack in my screen.
Which seller did you buy your replacement screen from? And was quality good?
I will try and post a video, but this is my business phone and am in a rush to get it back to fully usable condition. Thinking i may end up buying the LCD/Digitizer/Glass as I have never separated a digitizer/glass from the LCD before.
I just got mine back today from an LG service centre. I had the same crack about 3/4" from the bottom with no functionality below that. Total cost of repair was $95. Not too bad since I saw the LCD/Digitizer for $50 on ebay. Plus I retain my mfg warranty.

Sasktel. LG uses a company out of Ontario for the phone repairs in Canada. Their name is All Tech Neek. I also contacted them independantly and they will fix your phone without dealing with your service provider. I just let Sasktel handle the shipping and stuff. Also, they require a deposit prior to cover shipping and assessment labour incase you decide not to have the phone fixed, but the deposit goes toward the repair if you decide to have them repair it.
Hope this helps!!

I am trying to change a cracked screen. What would you say is the easiest or best way to heat the phone up to remove the front screen?
I just ordered a new lcd/digitizer and it didn't come with any adhesive. What kind of adhesive should I use and do you know of any stores that sell it. Really don't feel like having to wait longer while I order it.
Btw, I am I Canada (Calgary area) if there are any canucks that know where I can pickup what I need?
Thanks!
