DO NOT attempt to disassemble your phone unless you can handle the possibility of breaking your phone, both financially and emotionally. Also keep in mind that this WILL void your warranty.


First thing's first! Remove your battery cover, battery, sim card, and sd card.

There are six screws on the back of the cover that we need to remove. Two of them are a little tricky to get to. What you need to do, is GENTLY pull up in the center of the battery latch, and then pull out, it should slide out relatively easily. The final two screws should now be reachable.

Screw locations:

The final two screws:

Remove all six screws and keep them somewhere safe. Every last screw in this phone is identical, so no worries about getting them mixed up.

Start with the bottom end of the phone first, and begin to pry the screen out from the edges. The bezel and back cover of the phone are all one piece around the screen. The bottom edge should come off with out too much trouble:

Here comes the hardest part of this entire process, releasing the last clip at the top from the rest of the phone:

With a plastic tool or very small flathead screw driver, VERY carefully lift one side of the case as shown in the picture above, slide the driver head in and gently pry up. The last clip should come free without too much force.

As you can see, it is a very beefy clip.

Everything with a red arrow needs to come off of the mainboard to enable removal.

Once those are all disconnected, you should have something like this:

There's a couple more things to do before we can pull that mainboard off.
First, we need to unlatch the ribbon cable from the speaker. Flip the back clamp on the connector up to enable release of the cable, like so:

NOTE: There may be a piece of blue tape over the connector and cable. Carefully remove it before performing this step.

There's one last screw to take care of:

Once that is out, you can pull the right side of the board up, and the left should follow pretty easily, just be careful of your cables and be absolutely sure everything is disconnected before you pull that board off.

Here is the front side of the board with all of the shielding removed. This basically entails taking the micro sd and sim card board off. When doing this, be sure to disconnect the cable that runs from the top board to the underside of the main board.

Apparently I somehow missed getting better pictures of the underside.. >.<

Here's the backside of the screen assembly. This is applied with an adhesive, so please, for the sake of your phone, do not attempt to remove this unless you are a professional and know exactly what you're doing and how.

I am not one such person, so I made no attempt at removing anything else.

For those wondering about the bluetooth chipset and whether it is in fact the same chipset in the Galaxy S (meaning we would have FM support) I am sorry to say I could not find the bluetooth chipset. The Broadcom chip on the frontside of the main board is the BCM4751 which is only a GPS receiver.

i.e. there may still be hope for the FM receiver.

That completes the step by step teardown of the Samsung Captivate. Thanks for reading :D

Great job on the teardown. I was under the impression that the Captivate has fm radio built in. I guess i was getting that feature mixed up with the HTC Aria

Finally! This is great, thanks much for doing the teardown. If you haven't reassembled yet, would it be possible to get a couple more high-res pics of both sides of the main board so we can read chip numbers?

Unfortunately I don't have an area where I can get a real even lighting so that I can get good pictures of those numbers, all 3 of the larger chips on the back are all Samsungs. If I pull it apart again, I will try to get better pictures of each of the chips.

the one to the left in the photo reads KLMAG8DEDD A101
The one with the white sticker on it is the hummingbird chipset.

The smaller chip in between, however is not a samsung chip.

Almost everything on the top side are TriQuint chips. Theres one square, covered with a black/blue tape. Then theres 3 rectangular chips along side it, 2 sideways and one vertical. Most likely the wireless chips for Edge, 3G and HSUPA and HSDPA.

EDIT: The SWB-B23 chip, responsible for WiFi and Bluetooth is found on the Galaxy S i9000, it is also here on the Captivate.

Are there any tamper-proof stickers or what-not that could void the warranty that we need to watch out for? The BB Bold has this small sticker on top of the screws so that ATT or BB would know that it's been tampered with? Also, can the S-AMOLED screen itself be detached from the chassis? Reason is, there is dust build-up on the creases around the screen and would like to clean it once in a while. Thanks.

No tamper proof stickers, and taking the back cover off will give you access to clean what you want.

The super amoled is bonded to the screen.

Sorry, but I might have not made myself clear, what I meant was the screen including the s-amoled itself from the surrounding casing. Not the glass/screen on top of S-Amoled.

Nice tear down.

Looked through your pictures and compared the the Samsung I-9000 teardown pcitures. Looks like the camera plug in module is definitely different, though it uses the same chip. I was hoping that we may have been able to buy the module and replace the captivates and mod the housing to get a FFC. Doesnt look like we will.

Heres the link a I-9000 tear down

It seems the BCM4329 Broadcom chip comprising 802.11n + Bluetooth 2.1/EDR + FM radio (transmit/receive) is integrated into SWB-23 as per h t t p: // www .angcore. com/YOSUN/DETAIL_SWB-B23.html
But the i9000 uses the FM radio from SI4709.

It is possible that Samsung is using the 802.11n Wifi functionality of the SWB-23. But that chip doesn't support BT3.0. However since both the i9000 and i897 are advertised as being bluetooth 3.0 capable, we need to find out which chip is actually doing the BT3.0 function. I could be wrong, but as far as I remember the only other chip carried by i9000 that is capable of BT3.0 is BCM20751. If that is the case, then I am inclined to say that BCM20751 must also be integrated somewhere in the Captivate.

It is a pity that Samsung had to use so many chips with redundant functionality.

It is possible that the Captivate carries that same BCM20751 chip, but I was not able to find it in my inspection of the phone.

Second picture from button, the circuit board in the hand, what's that little round connector on the top left corner? If you trace the circuit, does it go to the GPS? And can you see any other aerial wire for the GPS? Seeing the tear down also of the i9000, I see what looks like an aerial on the back plate, but it doesn't seem to be connected to the mainboard.

@sjdean: I think the connector you are referring to is the connector for external antenna extenders, which can easily be seen if you take the backplate off of the phone. Also, I don't know if anyone has noticed or mentioned it, but there are 2 specific contacts that protrude from the mainboard and make contact with the metal backplate. You can also see specific locations on the inside of the backplate where there is no paint, presumably to allow conductivity to the contacts.

I posted in the other thread about the Captivate teardown with some chips I managed to identify, but I'll go ahead and post them here too for reference.

The touch controller as an ATMEL MXT224
The modem chip as an Infineon BGA735.
There's also a TriQuint TQM6M9014 RF transceiver.
The broadcom chip on the front of the mainboard is confirmed as a BCM4571
And on the backside I managed to find another very small chip with the following markings:
MAX8998
EWQ 1012
EA89
I can't find out what it is. Possibly just a voltage regulator, but I'm not sure.

The front speaker and rear speaker are all part of the same assembly. (That means its REALLY easy to replace. Pull out the old one and put the new one in)

IIRC, the speaker is hosed in Its own module just like the camera. that means as long as you can manage the first step of getting the back cover off all you've gotta do is pull the old speaker out and pop the new one in!

    Yea, you can see how it separates from the bezel in the writeup

    I have used mobile tech before and they were great. Just wanted to quickly replace it if I could

    I agree with BWolf56 in ur other thread u recently posted in...that this is ur problem more than likely. I searched for a while on the web and youtube etc and couldn't find anything about that pin. Opposite of it on the otherside of the phone is the external antenna port. But my guess would be that that pin u r missin has something to do with ur problem.
