[Q] Identify S4 Components - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hey guys,
Quick question for everyone regarding some of the S4 hardware layout. I'm hoping someone can tell me what the 2 ports on the S4 labeled "?" are used for. They look like antenna connectors of some sort. If I have any other labels wrong someone let me know too. Thanks

Thats kind of what I thought. Any idea if they are active or passive?

Get a pig tail that will connect to that port and see if your signal strength changes, thats the only way i can think of to test it. be careful tho, there were people jacking up there phones plugging in the wrong connector.

Depends whats wrong with it. If connection is dislodged a fix might be possible. Otherwise you can replace the speaker.

You're the third person to do this on this Forum. Problem is finding the parts. I think one thread suggested someone on e-bay had some but I could be wrong.
Cheers

[INFO] It's Here! (Pics)

This thing is awesome. Sorry for the bad pics I just took them quick as I'm going to go play with this! Build quality is outstanding, zero flex on the back from my unit. It's incredibly fast and seems like a really premium unit.

Congrats.....you bastard.
Looks like the box took a bit of a beating. Glad the unit's good and working nicely. Have fun, try not to gloat TOO much.
I find the fact that the weather widget display is "Not Available" humorously apt for the current ordering situation.
You might want to blank out the serial number in the pics bud. If you DO get a chance to get the keyboard dock cheaper they will ask for that, and if everyone knows your code... someone might use it and you'll be screwed. Plus warranty claims etc.

who can help me fix my HTC HD2?

Hi I have a problem with my htc hd2 leo

Well, when it is burned like you said, then it will by very hard to get a new transistor for it. So maybe you could search on the second hand market for a HTC HD2 with a broken screen and change that part on the photo.

will this work on N7?

I know it says it's for xperia play, or something, but the guy said in his thread that it should work for all OTG devices.
I however don't have a usb hub right now, so if anyone with soldering skills wants to try this, let me know if it works.

The potential to brick your device by shorting it out is high with this, someone with balls of steel would need to test it.
basic circuitry looks okay but I don't know if the sony devices do anything funny to allow for this on their official dock, you also may have to experement with different ohm resistors to find the sweet spot for our device.

any help PLEASE!
You'd have to get a replacement motherboard for your device. As there is no way you can fix that yourself, unless you are a certified or skilled electrician.
Ok man dont worry just search the schematic of the board and you will find there the number of those 2 pieces. It will be kinda hard to buy them but... if you have it then you'll need a soldering station with veri fine tip or you can solder them with hot air soldering station.
