Where is the Antenna located? Top or Bottom of phone? - T-Mobile myTouch 4G Slide

Just curious, were the antenna or antenna(s) are located on our device?
I would think the bottom since the top of the back side is occupied by the camera...
Anyone?

Could the ring around the camera and the metal strip on the back be used for the antenna?
I'm thinking there's probably one at the bottom of the phone...
Anyone?

Anyone?
I have a feeling the metal strip on the back is used as an antenna. If you look at the inside of the cover there are two little connector pieces that touches the camera metal ring, which is connects to the metal strip on the back cover...
Can anyone confirm this?

Dunno for sure - my time has been pretty tied up in this phone and I haven't gotten around to a lot of what I want...finding a teardown has been one of my to-do's.
I can say from my extensively thorough testing of GPS/ A-GPS on the phone that the signal is hindered by placing your hand around and over the top of the screen in the upper left corner, including covering the volume controls from the side.
I have been watching readouts on my screen which get weaker when placing my hand in that position and stronger when removing it, almost instantaneously...duplicated more times then I can count.
Not exactly what you were looking for, but one more puzzle piece to play with.

Thanks for the input!
Yea I think you're right...It's somewhere in the upper (top) portion of the phone where the camera is located. Also as mentioned, I think the metal ring around the camera and the metal strip on the back cover is also a part of the antenna.
If you take the back cover off you'll see two little connector points. Most phones utilize the metal around the camera when can.
Hope to find a tear down soon....Glad to see someone else with interest of a tear down....Always fun to see a break down.
Cheers.

HTC Apache Audiovox PPC6700 LCD / Digitizer Replacement Instructions

All I have right now is this from someone online who said he had the instructions. If anyone has clear outlined pictures to do this, please post it.
Thank you!
"There are additional screws that need to be taken out. You have to pop off the housing on the top that covers the camera and the antenna port. there will be at least 2 more screws there. Then you will carefully have to pop off the back starting at the bottom by where the stylus is and pull that off. There is probably going to be another screw holding the board in place. It has been a few months since i have done this. Then the board comes out and you have 4 more screws these are phillips heads. That will take the back housing off of the front. Then 4 more screws to take the back plate off of the front housing."
Places i've tried to find LCD Digitizer replacement instructions for cracked LCD
The Audiovox PPC-6700 I have has a cracked screen. I got an LCD replacement, but have no detailed instructions on removing the cracked screen. Here are some useful places i've looked at to find the answer to this issue if it helps you:
http://forum.xda-developers.com ... of course why else would I post it here

Not the best...but better than nothing....
Here are my own instructions I started... maybe someone else can expand/refine/clean this up. I'm done with this finally. Changing this is possible, but not necessarily easy. There's this tinny like sticker on the OEM LCD in the phone that's a real pain to pull off of the LCD. The pictures are terrible too...sorry...again..something= better than nothing.
In the end, it works...everything except my toggle does not click in like it used to...that's probably because of that rubber piece I did not know about. (A rubber piece fell out when I was taking it apart and I never figured out where it was supposed to go..so if anyone knows where that belongs and how it should be oriented..please post it.)
I took the stylus out.
I took the miniSD plastic blank out/ or miniSD memory card out just in case.
I took the battery cover off.
I took the battery out.
I set the camera lens in between the picture of the flower and the sun in the back.
I took the rubber piece out..there's a little probe looking thing behind it. (Probably was not necessary to take out.)
I took the back camera cover off. (Remove two Philips head screws with a PH0 head.) There are 7 notches holding it in place. [One above sun/flower adjuster, one slightly to the right above the flash hole, one above the rubber piece, one a tiny bit below the rubber piece, 2 on the insides at the bottom of the philips head screws, and one to the right of the speakerphone.]
I took the green circuit board that has camera flash behind the camera cover off. (Pops up off slot after removing one philips head screw.)
I took the camera unit off. (Do not pull up on camera, just pull the green board up off. The camera is sitting there, the board is wired like the camera flash board was plugged in, just pop it off.)
I took the cell phone antenna philips head screw off that is above where the camera was.
I took the 4 torx .050 allen head type size screws out to remove the back plastic cover of the phone off. Be very careful prying this portion apart. There are probably about 14 notches maybe that holds the back plate on. Some say to start trying to pry it apart from the antenna, but I was able to pry it apart from the bottom part of the phone on the antenna side... not where the antenna is. Be extremely careful how you pry this apart. You have to watch out for the speakerphone wires, there is a plug for what I think might be the keyboard and or LCD, the vibrating weight, and the main board itself... you don't want to scratch or sever any of these parts.
I slid the antenna off of the main board. Lift the board and gently pull up and out the black antenna.
I did not take the speakerphone off, but it looks like you have to pull the wire from the board that would still be attached to the back plate. The vibrating weight is also on the backplate.
I took the main board out of the phone. Keep the slider in mind between the IE button and the recorder button on the side of the phone. The black portion on the main board needs to line up with the actual switch you would slide up or down with your thumb on the side of the phone. When pulling the main board out, slide open the keyboard fully/halfway. Watch for a black rubber piece.
I removed the 4 philips head screws that hold the keyboard portion of the phone to the LCD portion of the phone together and lifted them apart. There is a silver/grey tape that you need to pop up the data cable and pull the tape off to completely separate the LCD portion.
I removed the 4 torx screws from behind the LCD screen and carefully took the LCD portion apart.
...ok well it's getting quite annoying to try and write everything I did after this, but it's pretty self explanatory. If it's not, you probably should not be changing your LCD in the first place anyhow. In order to release the LCD ribbon, the plastic piece at the end will need to pop up at an angle..it's kind of like a winch.
Here's a similar phone that gets taken apart if that helps you out in any way.

re
what is the toggle you are refering to? i took mine apart to clean around the screen without any instructions, and everything still works, but the digitizer has had it, where did you get your replacement from?
I got my replacement from eBay. goldelec
The LCD had a weird rainbow thing going on in the center of it, that you can see if you look at it at the right angle and the bottom corner looks bright white when the screen is on for an extensive period of time. Again, it works...better than what I had. I did not get great instructions, but what he sold me worked fine.
The toggle i'm talking about is the button in between the call and hangup buttons on the front face of the phone. That toggle switch just does not seem connected or stiff like it used to be. I can't "click" up/down/left/right or select anything. I am convinced the rubber piece goes behind it somewhere somehow. I just have to take it apart and figure out the orientation of it.
thanks for these pics & instructions, I just replaced with a part from goldelec on ebay as well (though the auction list instructions as part of the deal, they didn't come with my shipment, so your play-by-play was invaluable)...and there's no screws left afterward! Always a good sign.
Maybe this will help some people...

lcd replacement instructions
www.htclcd.com has a lot of good lcd replacement instructions also
as well as the LCD's
I just took apart two 6700's today (had to replace the buttons on the face and the circuit board underneath so for now I scavenged the parts from my backup phone)
anyway the phone is surprisingly easy to take apart and surprisingly straight forward.
You do not even have to organize the screws as there is ONLY 2 kinds (I like that) and its obvious when to use each as they are very different in size.
a straight head will take out the star bits if your careful (if you have one of those many different jewlers drivers kits you will find one that fits just fine)
OK cover card stylus battery out.
4 screws. 2 dark large at the bottom 2 small silver at the top of the battery cavity (the one on the top right is hidden underneath a small white sticker)
Now the "top" plastic section comes apart. (the area with the camera) make sure the camera switch is ALL THE WAY one way first it will make things easier later.
Lift from the bottom LEFT there is a tab under the black antennae casing and a tab on the right next to the speaker. Pry gently and it will "pop free" don't YANK as the speaker is attached still.
Pop the speaker out (leave it attached no reason to mess with that wee connector.)
Remove the single screw from the center of those board. NOW caution there is a square white soft "seal" around the led do not lose it.
finger tail "pop" the boards out.
Camera module same thing finger nail "pop" the module pops out but those asside.
3 more larger dark screws remove them now.
Now you need to remove the back half the the shell. Lift with force till you have a small opening and start poking at the hold downs till you can work it free. the hang point is again the black antennae housing. This was the most difficult part to remove and it was not that hard. Use care so it will look clean when you put it back together if thats important to you.
Now you see the mother board. one single screw is left silver middle right side (away from antennae)
Time to remove the main board. you need to use CARE here as its "catched" on opposing side (the usb port and ear piece ports) and the Black antenna housing.) and also atached via a short ribbon cable.
Once you have it free SLIDE out the keyboard this will give you a lot more slack to lift up the main board and tilt it sideways.
Peel the tape carefully once its free it will "pop" free using the same style connector as the camera board etc.. used.
remove and put asside.
now remove the 4 screws holding the keyboard to the phone. its free put asside (those are the only 4 that are different just LEAVE them in there holes they will stay if you don't toss it around)
now remove the 4 black screws holding the back of the keyboard housing down. Pop it free (its not hard there are poke holes made for this like flat screwdriver slots)
once you do this the ribbon will slide through the opening no worries.
now act like your breaking a glow stick and "bend" the case sides so the screen can be popped up a little.
lift the orange tape and you will see a different kind of rubbon connector. its white with a tiny black flap. use a finger nail and lift it will ROTATE 90's to vertical. the ribbon cable will now pop free.
now remove the 2 screws holding down the circuit board. remove it and the button pad (this is why you had to lift the screen a little or these won't come out.
Thats it. I did not go further than this but I do not remember it "looking" like it would be hard at all to get the screen and digitizer out.
This is all straight from memory so read ALL this first and adapt as you progress. DO not take it verbatum.
If something does not want to give ASSUME you forgot a screw and be extra diligent to find it before attempting to increase the amount of force you use though sometimes it just "needs" a wee more force.
Good Luck
I should have taken pics which I usually do when I do this again I will take detailed pics.
Ohh dolt reassembly
do everything in reverse. thats it. here are some tips for the tricky spots.
Reinserting the button pad ribbon. IE reconnect the ribbon BEFORE you put it in. its a lot easier. make sure its in all the way push the flap back down push the tape back down. Easy
Rescrewing the keyboard into the main shell. Get it roughly lined up and LOOK INSIDE one of the holes as you wiggle it around. you will see the screw hole quite clearly when it appears. insert and screw down. Do one on the other side easy as pie.
When you put the main board back in you need to make sure the VOLUME slide switch is in the MIDDLE neutral position so it it lines up with the volume slider itself IE it has to move BOTH direction misalign this and it will be jammed one way or the other. Pop it apart and try again.
When you put the final cover back on make sure the SWITCH for the camera is in the same direction as the plastic lever (the actual switch) so that they line up when you snap them together.
thats it. Really not that hard.

[FIX] Annoying creaking noise

I just started developing this odd creaking noise near the bottom and sides of my S4G. Even with a Seidio Active case wrapped around it, the creaking can be felt and heard when hitting the bottom buttons.
The fix is pretty easy. You just need to decrease the amount of movement the back cover has.
I had some .010 mil fiber (fish) paper laying around so I cut a small square that covers the sim card and microsd card area. You can probably use something else, but hey, why not use some insulated paper if you have it.
Lay the paper on top of the area and then slowly place the back cover back on. No holes are in that area above the sim and microsd, so no worries there. You should see an immediate improvement
I needed more than that to stop the creaking/screen movement.
Pathetic we have to go to these lengths

What did you have to do?
I tried used two squares of paper, but that made the back bulge out a little too much to my liking.

I took a post-it and folded it twice. Then placed it on the bottom right area and closed up the cover. For me when I press down on the bottom right side of the screen the whole screen sort of depresses a bit. Only way I could get rid of that was to place the paper in that region. Problem solved.
Post it would have been my backup method
Sent from my HTC Sensation 4G
buy another battery, i recently got an anker also had the creaking problems, noticed the anker is a TINY bit thicker than the stock battery and it removed that problem completely. and that anker battery was DIRT cheap
I just lined the case with some scotch tape. from the bottom to about 3/4 of the way up. I just went around the antenna nubs and the usb hole.
Posted this in another thread, but felt it was valuable here too...
Got the creaking here also, definitely a design flaw. Being obsessive with my devices i couldnt live with it!
I do not recommend putting paper in the cover to fill the gap, as this is just expanding the cover further making it even MORE loose when the paper is not in there. Also i wouldn't recommend it because the paper pushes the back cover out a little more, you may loose a connection for the ground. Which is the little metal springy thing, half way up the right hand side. Obviously its not a good idea to 'push' the cover further away from this ground spot. I have heard that people have had issues with screen responsiveness due to a static build up from not grounding properly.
What i did to fix this problem was a bit of a kitbash of sorts.
Mine was creaking on the bottom right area, like most. The problem is there is too much play between the little black catches on the battery cover and the latch on the handset. Instead of filling up the gap between the phone and the cover (Ala paper, card in the cover) I closed it!
What you need to do is get some very thin plastic film. Like that on kids toy packaging etc. Not the thicker stuff though. This stuff would be under 1mm thick. It came as a viewing window in the box my new wallet came in. So you can sorta imagine what im talking about.
I cut a piece about 10mm long and as wide as one of the two little black catches. I applied a VERY thin coat of super glue to one end of the film. Just enough to cover the area under the catch. Then i carefully placed the film with the superglue on it under the catch, and then quickly applied some pressure to it with some tweezers. Then i carefully cut the excess off with a pair of finely tipped nail scissors.
The result is that it now PULLS the screen/phone INTO the cover more by making the little black catch thicker. Not the opposite (paper method), which pushes the cover out, creating a further problem of adding more paper under the cover over time as the cover expands/loosens to compensate. Not to mention a possible grounding loss and resulting damage.
Hope this helps some people that have had multiple replacements or could not be bothered replacing for such a cosmetic issue. (Like me). It definitely works, just got to get your surgeon on and be accurate with your placement of the film.
Apply this to what ever side creaks the most, and bam its gone. Nice. Solid phone... again.
If anyone wants more specific details etc, im all ears.
Regards,
Matt.
will try it with an double side film ...
i mean a film that hold back cover and phone together ;-) i think doing paper in there will do damage with time
I contacted HTC and they sent me another/new one. No more creaking!

I have the same problem too. And it just seems to get more and more "cracking"

[Q] Aluminum Battery/Sim/Camera Cover

Hello Guys,
I was loking for hours to find Aluminum Covers for the DHD to replace the plastic parts but wasn't able to find them (if they even exist).
I only know that HTC never officially released them.
But since I saw the MAO Method they used on the One S I wanted the same for my DHD
Does anyone know a shop where I can find these covers made of aluminum?
Thanks

You mean the doors? Won't find them because the clips to hold them in place wont function being made out of aluminum. Thus why only the immobile parts are made of it. If that is not what you are talking about, ignore me Not to mention the signal loss of grounded aluminum over the antennas would be crazy.

But would't it be possible to make the outer part of aluminum and just the clips of plastic?
But ok seems to be impossible sad to hear

possible yes, but the biggest factor would be that each plastic door covers an antenna. the led flash covers the gps, the battery covers the wifi, and the bottom door covers your cellular antennas. So replacing those with any kind of metal would connect them to the outer shell and ground them, almost completely shielding your phone from signal.
I just looked at the antenna except of gps (didnt want to open it all up). Wifi is just simply spaned mabe same with GPS. Only antenna that runs a bit through the door is the Sim/SD Door Antenna but if you would take a pretty flat and small cable you could run it through the left hole beside the two connectors. I dont know much about antennas but this could even make a stronger signal doesnt it?
p.s. The hole i mean is a bit upper left the two connectors (phone up side down)

the simple answer is no. antenna length is specific to the frequency it uses.
I understand you need a specific lenght of the antenna for certain frequenzies. So the cable that would be needed to connect the two connectors should have around the same lenght as the the Antenna in the plastic door.
Do you know how accurate this would have to be and how do they realize to use different frequenzies with one antenna GSM around 900 MHZ and WCDMA around 2,1 GHZ?
Anything can be done the real question is how much are you willing to spend?
And is it really worth the trouble to go through trying to fix it?
You should just get a new phone instead of changing the parts.

[Q] Opening lower case plastic flap

Morning!
Has anyone yet taken a closer look at the lower plastic flap of the case? The upper one with the power key opens readily to accept the SIM Card, but there also is a gap of about the same size on the lower part of the phone, just below the beatsaudio logo. This one has no opening to pry open with the fingernail, but i could nudge and move it a little by ever so gently prying with a tiny flathead screwdriver. There also is a small hole pointing within this flap on the very bottom of the phone.
Q: What is the hole? Drainage hole in case the phone gets a soaking bath? Hardreset microswitch? Or is it maybe a releaser that unhooks the flap and allows for easy removal (similar to the holes beneath DVD-Drive trays to remove a disk if the Drive is broken)?
I am trying to figure this out as of now, but for the life of my I cannot find a slim enough needle to get into the hole. Guess I will need to grind / file something down to see if something happens when inserting it.
Has anyone investigated this yet? Anything interesting beyond or is it just a second flap with additional antennas and no access to interesting bits and pieces?
Wonder is it where the battery placed? Perhaps there are website trying to disassemble One S to see is it easy to replace the internal battery.
If you are referring to the tiny hole at the bottom of the phone, that hole is the mic. Wouldn't advice on putting anything in there
lol its the microphone. in almost all devices it is locates there
Funniest sunday topic
You made me laugh... I remember first iphone users were talking about " OMG one of two speakers under the phone doesnt work OMG OMG "...And someone told them " It is mic ! " LOL....

I don't yet have the HOS. But I can tell you that the little hole in the bottom of the HOS is the phone mic...
And be aware that doing what you intend to do will eventually void your warranty... but go right ahead... it's not my money if you screw things up...
I have taken apart enough devices to know what I am doing (except for the stupidity of not considering the mic hole because they have becme so invisible these days that its easy to just forget about them heh...).
I changed broken digitizers on DHD and did a complete disassembly / reassembly of a Desire Z that took an Soda bath and both devices work to this day. I am just hell of curios regarding the PCB layout of the One S, mainly for the storage question (soldered or aftermarket slotted microsd mounted under the hood)
And FYI, under the lower flap is just another boring antenna and another plastic cover, no more screws like behind the top flap. Do't have the right tools here to go any further without actually risking damage, but after easter I will have a closer look at it in the company. Unless iFixit comes out with a disassembly tutorial faster than that hehe.
Warranty? Well warranty. I've had a few devices now from HTC and none ever had to go to service. And with the knowledge of how to fix it comes the option of just paying for the OEM spare part from some retailer later on and fixing it yourself in 1 day instead of sending your phone in and waiting on it to come back for 1 week or 10 days.
But thanks for the hint, I might have actually forgotten about that.

[Q] Speaker module

My N5 just got dropped in a wet place (definitely wasn't the toilet!). I grabbed it real quick and switched it off.
I have taken the back panel off to dry it out (will leave for several days before I touch it again).
When prising off the back panel, I have damaged one of the contacts on what appears to be the speaker module.
Can anyone tell me what the metal strip in the attached is connected to? Is it the mic?
Thanks.
I have just discovered it's part of the antenna loop.
Any bright ideas of what I can repair it with?
And which antenna is it (it's the one with the black wire on the right hand side when viewed from the rear).

The little one is 2G/3G I think. The bigger one is 4G/LTE I think.
I'd really love to know to fix this too...a blob of solder? A strip of tin foil? No idea!
The metal strip on the outside of the speaker module has come away on mine too when removing the back cover...only a very small section because I noticed and tried to minimise damage.

It didn't make any difference to my signal when I had it like that.
For other reasons though, I replaced the speaker module. This was really easy and the part was really cheap. Probably the easiest way to repair it.
Thanks. That's really good to know re: no loss of signal.
I can confirm this too...I had no loss of signal either, even with a large part of the foil strip missing.
