Antenna tests on T-Mobile - AT&T Samsung Galaxy Note I717

I disassembled my I717 and T989 to determine if I could find any major differences in the antennas. I managed to connect the coax lead from the base antenna on the I717 to the PCB leading to the corresponding antenna on the T989, but it didn't improve upload performance. I think its the receive antenna.
There is 4 antennas from what I can see, the two top side antennas are probably for transmit, the rear door one is the GPS patch antenna, and the base one in the speaker module is probably for receive. I'm just deducing this from the fact that the two antennas I think are transmit are very close to the large IC chips, and you'd want to minimize signal loss by keeping things close.
Luckily the unit is easy to split apart. If I find that a simple antenna mod improves upload performance then I feel it would be an mod that most folks could accomplish themselves.
Perhaps someone has a service manual that could be of help?

Heres a pic of the I717 connected to the T989 antenna. Too bad I this wasn't the one as its the only one that is not encapsulated and is easy to modify.

Nice to see you with a note roto i love your work

Hey roto,
I think that antenna at the base is the one for uplink. Very weird thing ... when I hold the phone in landscape with the volume rocker up or with the phone upside down my upload speeds take off. When I hold the phone right side up with my hands covering the base, my upload speeds diminish. Wonder if there is a way to easily move that antenna ...

I'm happy ur still looking into this man I don't wanna go.thru the hassle of buying a new phone

i just redid my "tinfoil antenna but made it longer up the length from the S-Pen to the "white sticker" I gained a full bar of reception. as to up/down speeds no real difference as my carrier is poop.

I have also covered the bottom section below the battery, leaving a hole for the speaker of course

What are the two holes on the back of the phone?

To the left of the speaker grill. Can't figure it out for the life of me. It has contacts so it has to be something.

External mic for speaker mode, when you flip the phone over? Completely random guess.
pretty sure I read a review that said the rezound has 2 noise cancelling mics.
Those holes are for the antennae. The noise cancelling mic looks like it's on the side. The thunderbolt had similar holes.
I asked the guy at the Verizon store and he said it has to do with wireless charging but that didn't make sense to me since it has contacts and wireless charging requires a different back cover.
I did notice some cases have a cutout for them and some don't.
There's no mention of them in the user manual.
Yeah. That is the main reason I would like to know. My case doesn't have the cut outs and I don't want to cover them if they were mics.
Surely there wouldn't be microphones built into the battery cover though.

If you remove the battery cover, you should see that there are copper contacts on the inside of the cover, and that the holes in question are the mounting points of those contacts to the battery cover. To my knowledge this is the only function these pin holes provide, and I see no way for covering these would have a negative impact on the device.

Holy test points!
I can only imagine that the holes that lead into the CDMA antenna contacts are for test points, as there is probably little reception inside the factory and an auxiliary antenna might be used to obtain a signal. OEM accessory covers, like the wireless charging and extended battery covers, do not have these holes, nor would they be needed since they are not supplied with the base unit.

[PICS/Guide-ish]Taking your rear housing off

Hi everyone! While waiting for a donor phone to be dropped in my lap at work today, i spent about 20 min taking my phone apart to see what was inside......So please enjoy, and I have some questions about the shielding over the radio components.....any ideas on taking it off? I know i should de solder them but without burning the board? whats the best approach Ive never soldered so please post a link or something. I really want to take a look under those shields. So without further ado taking your housing off!!!!!
Take out all the screws and stuff....helps if you have a fingernail or a pick for pulling it apart too!

Take the housing off until its in 2 pieces like this one.
Pull this screw out by the sd card slot
Pull out the first ribbon cable
Plus this one too!
Pull this black thingy
Pull the sticker to expose the mysterious radio components
and your all naked!!!
now some other pictures and stuff!
Sim card slots n stuff!
Shielded components
Any ideas on how to get them off?

I can tell you from experience that this is a well built phone. Pay close attention to secondary seals under the rear housing and usb/hdmi ports. I had a customer come in with one that had a coffee bath and still worked. The only parts that got wet was between the lcd and digitizer and between the lcd panel and reflector (the mopho was face down on a table when it happened). Except for the coffee staining the reflector panel in the LCD assembly it was good to go after desiccant/hotbox treatment.
U need a hotflow soldier to get those panels of...or bake it in a oven but u will ruin it
I deff don't recommend trying to take those off even if you have the right tools
That stuff flat out takes experience and a good hand

So when you do get this opened up, keep in mind if there is a n lte chip, it will be a dual wi-max/lte chip, only one has been made between a chip company and motorola and motorola has only made one wi-max phone so ill place my bets the dual chip is in here, ill try to repost with a picture of what it should look like

No LTE Support for Photon
No need to find a sacrificial lamb for your curiosity, our phones wont support LTE at all. The Photon has the Wimax Chipset Version bece3502, the Dual mode LTE/WIMAX chipset is the bece5000.
So there you have it, Sucks but its better to know then to ruin a phone.
Ive heard and read its just running the Beceem 3502 drivers for now, ive also heard of sprint representatives saying an update will come for the photon to support lte when theyre network is expanded, what other reason would motorola hide the photons full hardware information until january, when sprint releases theyre "big secret" at ces which im guessing is LTE

External Antenna, need patch cable info

So the story goes we were in northern Maine on a fishing trip with no signal. I would like to make an external Cantenna, but need the correct patch cable to go from the phone to the cantenna. I don't care what connector is on the other end as I will source the correct connector based on the patch cable. Anyone know what spec the external antenna port is on our phone?
ps I know where the port is, just don't know what it's technical name is.

Be careful!!!
I've read that those ports on the back of the phone are used by Samsung for testing purposes. Be careful when tinkering with those as you might permanently disconnect the internal antenna and ruin your phone. I was interested in making an external for my old Epic 4G Touch and decided not to after what I'd read about using those ports. Here's a thread with some info for you:
http://forum.xda-developers.com/showthread.php?t=1484314
If you are successful in joining a Cantenna to one of those ports, let me how you did it.
Nice dinner there.

Saw the exact same problem back with the captivate, poor guy trashed his phone, since the antenna connector never reset; apparently it is just the way Samsung handles antennas in their phones. There is a powered amplifier on the market that works without a direct wired connection, if I remember it will give you..... maybe 20db (guessing from a suspect memory) ... I could probably find the link, if you don't already have it.

An engineer friend made a reflector that focuses the signal at his cell phone. I think he used a stainless steel bowl with a hole in the bottom so it was more a funnel than a reflector. You need to know where the cell tower is so you can point the bowl, though.

Sounds like a good idea, but not sure it will work where we are. Lots of trees in the way. It sucks that Samsung would not use the external antenna port the same way as everyone else. I'll contact sammy and see what's up.

Okay, this might help you, take a look at this little well priced tech marvel:
http://bestcelldist.com/samsung_galaxy_note_lte_widepatch.html
Pros ::::::It is just the coupling, This inductive coupling will tie into any type antenna system you might like. You can specify any end connector when you order ..
It is only $30 bucks. I know it is not as economical as a simple connector but an could turn out to be an excellent alternative if it turns out you can't mate a physical connector.
Cons::::::There is Rf loss without the physical attachment, around 40% , though with the right antenna/booster you could easily be sending fish picks to jealous friends back home....
By the way,the link below still sells the connector that will trash a Samsung Captivate, They do warn that attaching an external antenna "might" damage your phone in "rare" circumstances......they sell it for about $12, nice profit on some suckers $100 dollar loss.... some things never change, eh...... Let the Buyer Beware.

Official response from Samsung Support on G+:
Hi Travis! Unfortunately, we don't have any support information concerning this as we don't support 3rd party extermal antennas. Please reach out to the manufacturer for further information. Thanks!
No surprise really
I will keep the inductive version in mind. I will also update the post with any other info I find. Going to try an contact Cyanogen as his wife has a GNote and he works for Samsung.

Pretty much all high-end screens and capacitive digitizers are fused together these days, it's the process of choice to keep thickness AND glare down, needs less backlight power, gives better color reproduction, contrast and viewing angles, and it cuts weight a bit.
TL;DR The days of two-piece displays and digitisers are almost gone.
- Hmm, I don't see where the graphics chip is on the motherboard? The Exynos chip is pretty obvious, but I didn't see anything really labeling the graphics.
- Do the 2 heat shields serve to keep heat around those chips, or to disperse heat among a larger area? Does the heat shields come in-contact with the chips, or does it just hover above them slightly? If it's just hovering; we could possibly use some thermal pads to help with cooling if it becomes an issue at some point with overclocking maybe

Crack from headphone port.

Anyone else have a crack in their bezel running from the headphone jack to the screen border? I use headphones on this phone about every day so I'm not surprised the plastic cracked since it seems like any kind of force from the headphones could put pressure on that area where it is thin so close to the ear piece speaker.
Interesting thing tho is my friend has the same issue but rarely ever uses headphones. Also keeps the phone cased where I never have a case. Both phones have never been dropped either. I'm guessing it's a flaw in the design on that area, just wondered if anyone else has the issue?
I'll try to post a pic later btw

I too have a crack starting from the front of the headphone jack, and it heads to the left side of the front speaker. It is not very noticeable, though. I had been using a wired patch cord from the phone to my car's aux in port, and I have used wired headphones with the phone in my front pocket, so I figured the crack started from that use. However, I rarely use jack since starting to use wireless bluetooth headphones, and a wireless bluetooth connection in the car.

BY god i have the same crack, first time i looked i couldn't see it then i took off the case. it's so small at this stage you can't hardly see, unless you're looking for it, probably get worse. i hardly ever use the headphones too.

Give it time and you will. My wife and I both have this phone and we both have the crack. Definitely a flaw in the design.
I too have experienced the crack. My brother has this phone and he pointed it out to me just recently. Definitely could be a design flaw maybe this is a region where too much stress is getting applied. I thought it might have been his case- too tight. It a trident I belive. He does use headphones alot so that is adding to the wear. I carefully superglued it so not to cause any obstruction to the port or be obtrusive to the look of the exterior. I figure it will help prevemnt the crack from getting worse or even break off. Did not expect anyone really to have this exact same problem, even so many.
