[Q] Question about Galaxy S5 LDS antennas - Galaxy S 5 Q&A, Help & Troubleshooting

On the back housing, not the battery door, but the back housing of the S5 There are small indentations near the bottom. One of them has either a "V" for Verizon or a "P" for Sprint. I was told these were specific to the phone because of LDS antennas inside the plastic and could not be swapped with each other. My question, to anyone who knows more about this, are these antennas specific to the frequencies these phones use, or (what i believe) are they just simple conductors inside the plastic and the frequencies are determined by the hardware? Like i said, I was told i cannot swap the Verizon (V) housing for a Sprint (P) housing because the antennas (LDS antennas inside the plastic) were not the same and therefore did not operate on the same frequencies. But then I'd have to wonder, if the phone was unlocked how would it be able to then operate on another frequency without swapping the housings each time. If someone knows more about this (even whether or not these antennas in the plastic even exist) please help me out. And if you have sources please include those so I can read into this as well. Thank you.

GSM X9501 Shift has permanently attached case?!

Maybe I’m just misinformed, but I though that one of the main differences between the CDMA and GSM versions of the Shift was that the CDMA/Sprint version has an annoying case permanently attached to the unit, whereas the GSM version has a separate “envelope” style case. I thought this was true even in the US.
Imagine my surprise then, when my new GSM Shift X9501 (from Amazon) arrives with the same stupid case as the CDMA version. Is this everyone’s experience (at least in the US) or am I getting some kind of new stock?
The worst part, as with the CDMA version, is that you can’t just remove the screws and the supporting posts underneath them. If you do (and I did), you have three open holes at the bottom of the unit, and the upper and lower halves of the case are no longer connected and will start to separate.
Anyone know of a source for HTC parts that could sell me screws and feet from the caseless European/Asian model?
Thanks.
AFAIK the stupid permanently attached (screwed) case was requested by FCC for US only. Fortunately I am living in Europe. The “envelope” style case is very good for me.
wow lucky me then ....
Hmm. Lucky me then. I got mine from Asia even though I live in USA.

how about we trade. I send you my Envelope Style Case and the rubber feet next to the screws and you send me the attachable folding case. I would prefer that before the envelope case. Mine is in mint condition (never really used it)
we can pay our own postage...

hey,
would you be able to use my enterbootloader app and mtty and see "info 7" command for SPL version?
sorry this is a bit unrelated. but this is the first x9501 I see.
I got one of the new X9501 US versions..

as I previously stated, I am willing to swap. I was angered not to have the attached case...
lets trade
I'm actually going to hold onto this guy for a little bit and see what i like...
Once I learnt how to fold it properly not to get in my way, i didn't mind it.. too bad its brownish tan and not black to match my escalade Mwhaha
I am willing to trade.
Permanently Attached Case
Hi,
I have permanently attached case as well.
I am looking at Mugen extended battery and attached case will not work.
Are the 3 screws that keep the case attached holding anything on the Shift that would cause any issues.
When I call HTC support, they are scripted to advise you that you void warranty.
If the screws are not holding anything other than the case, is there any issue attaching the case when needed and could someone know that you tempered with the case?

Sorry, I havent check the thread for a while. I am still able to trade the Envelope
for the attached case.
Let me know if you still want to trade. I am keen on having the attached case
For those that want to remove the attached case:
If you take the three screws and grind down the sides of the heads to match the same diameter as the metal spacers, the screws will fit back into the holes under the leather case and tighten back up. You obliviously have to remove the metal spacers for this to work. Take your time, the screws will shave down rather quickly, especially on a grinding wheel. I've found if you don't put the screws back in, the two halves of the plastic case of the Shift will always be loose... doesn't seem safe to me. The only issue that I'm still having is trying to find the rubber "feet" that would cover the screw holes where the leather case was. If anyone knows a website to find a replacement battery cover, one could pop off the feet from that and stick them back on the Shift. If you try to put the screws back in without making the screw head diameters' smaller, they will get stuck about 1/4th of the way into the case, and will actually dig into the plastic, making it a hell of a chore to remove them again.
There is an easier way guys, swap screws, all the case screws on the shift have the same thread type and length, I swapped the top 3 wide head screws for 3 of the small head screws from the battery compartment, There are 4 screw holes at the 4 corners of the battery compartment, I used all but the bottom right hole(too close to the case) You need a T6 Torx driver and you have to put them in at a little bit of an angle but they fit fine.
I am also going to try to get the rubber feet to fill the empty holes left at the top. I am hoping HTC can provide these.
G
Any word on this?
Really hating the leather case... But i dont want todo anything until I find the rubber feet
Don't know if they have them small enough, but I have bought for PDAs.

tape removed on back of Ozone, loss of signal coverage

Hello to everyone,
I recently found a piece of hanging tape on my Ozone. I attempted to stick it back but it wouldn't stick - so I took it off since the back wouldn't fit on the phone afterward.
Since I live in a rural area, the tape seemed to have completely degraded my signal coverage! I have no verizon signal, only when I put my finger on the taped off areas. The moment I remove my finger, signal is lost.
Anyone know what type of tape this is and what I can do to replace it? Does it like... contain some strip of aluminum to strengthen signal coverage?
I'm disappointed in the ozone now, very very cheap.
The tape is located around the camera lense and extends around the speakers to the top of the device.
With all due respect-
Tomi
I just took a look at the back of my Ozone, that tape you are referring to is attached pretty snug like. As many times that I dropped my phone and that back cover pop off, there appears to be no wear or tear.
In hindsight, probably would have been better to have left the tape alone or smoothed it out so that the cover would close. It can only be assumed that the antenna is somehow meshed in that tape as it appears to be the only logical place for it to be due to the overwhelming size of the battery. Your loss of signal confirms this.
I hope you got insurance on your phone. Pay the $50.00 and have it replaced.

I'm not sure, I called the company but I have already used 2 claims on my older Motorola Q, one time when I lost it in my junior year of Highschool last year and this summer where my replacement fell into a swimming pool and I had to get another one. So I can't use the company anymore.
I ordered one of those "antenna boosters" from amazon, seeing that they are tape too - I''m wondering if that'll work?
I want to figure a solution out to what can be done if this happens to other ozone users who remove the tape from the back of the phone. The fact of the matter is, the ozone is a cheap phone if it has to have tape on the back of it just to sustain signal coverage. It really is a shame. Not only this, the phone overheats so fast when I use wmwifirouter to access internet, it's not even funny. I'm using my old Q now and that doesn't heat up to 25% of what the Ozone got to.
Does anyone know what this material could be and how i could replace it? would putting a copper wire or an aluminum piece help? I miss evdo rev.a, which my Q9m does not have and since I live in the woods with a 1.5 mile long driveway evdo rev. a helped a lot with internet service. Otherwise I have dial-up at home, and evdo rev.0 on the q is a lot slower. So I miss my ozone to a degree..
Thanks -

G1 Antenna mod

Hey guys, this is my first post here, finally made myself register
So i just bought the nexus one and now i have my old g1 free to be modified.
soon im going on holiday and i know for a fact that im going to have next to know cell phone signal, and no wifi. for some reason its in a 1 block wide dead zone, and t-mobile just cant seem to push through.
Ive taken apart my phone before to replace the digitizer so im fairly familiar with the inner workings, and id like to attempt to make an external antenna for my g1, so i can tether and get a signal when i cant normally find one.
From what i can tell by disassembling the phone is that antenna is basically , lack of a better term, the thin piece of sheet metal along the back of the phone behind the plastic. There are 2 of these pieces, one im assuming for the gps and one for the phone
How much luck do you think i would have if i attached a wire to this sheet, then to a extra wifi antenna i have laying around, or makeshift parabola? i have no inhibitions to tearing the phone apart as its my extra and i like tinkering with it.
any ideas?
You could try a wire, but it has to be coat hanger.
You may be able to increse reception a little by putting the phone at the focal point of a parabola but, then it would be dificult to use the thing.
I think I'd like to see pictures.
Sounds pretty possible, though.
Edit: old thread. -_-
this wiki could give some insight as to how it can be done:
http://en.wikipedia.org/wiki/Long-range_Wi-Fi
but where is the antenna lead on the mobo? I would get some 26 gauge wire and solder it onto the point, and start testing it out with a breadboard or similar connection...
You can't really just attach a coat hanger to a transmitter, you'll eventually burn out the radio. You need to have the proper antenna.

[Q] Which digitizer for my HD2 and where from?

I've successfully taken my HD2 apart now I'm not sure about the digitizer I need. My phone doesn't have a T-Mobile logo and it came with the leather pouch which I read means it's not the T-M version.
I'm looking for a new digitizer and the one that looks like the connector would fit says it's for the T-M version. Rather than go on about it here is a pic of my digitizer. I'm in the UK so if anybody has shopping suggestions I'd be grateful.

I can't say too much based from picture posted above ...
It could have already replaced unbranded digitizer or it's Telstra, European, Taiwanese version... Are the call and end buttons colored on your phone (green and red respectively)?
If You have enough money, about 89-120$, better choice will be to buy a LCD+digitizer assembly also named LCM, they will work at all versions of HD2, not only T-mobile or European, I tested the LCM from European HD2 with in a T-mobile version of HD2 ant it works perfect. So go on eBay.com and buy one
Call buttons are all grey. I've though about getting the whole combo but it's more than twice the price and I'm not exactly rich so it would have been nice to just get a digitizer. I was hoping there would a way to identify properly which digitizer I need. I've sent a message to one of the suppliers on ebay. I'll see what comes out of it.
According to this article the different versions of the HD2 aren't physically the same size in terms of casing. Do the LCM units fit all the same?

Let me help you:
#1.your picture is defining an uncommon/unbranded TMO(bile)US touchscreen(No doubt about, at least for me!), but grey hardware keys are for international HD2 model, probably you have a (let say) hybrid (home made)version between american(TMOUS) and international model;
#2.nevertheless, in your financial position, I'll look on ebay for an appropriate touchscreen model(there are plenty, most of them with very clear pictures like your's) for about US$30-40;
#3. if you want a combo, as far as I know(and pvii already said it) the 2 LCMs are geometrically identical, but the frame/chasis on which lay on the LCM is different(the american model is longer on 2,0-2,5mm);
#4. international model is cheaper & easier to find.
For more informations/help feel free to contact me!
Cheers!

May be it will be better if You post a photo of rear side of your display or at least say it's product number (from sticker on square copper pad, rear side), i.e. P/N:60H00300-00P is for T-Mobile and P/N:60H00295-00P is for international version.
If You don't have enough money for a european LCM combo, you can buy a LCD apart and digitizer apart, even from different sellers but you have to buy matching parts, both for European or both for T-Mobile version.
Thanks for the info guys. The serial number is the kind of solid identification that I was looking for. The serial on my screen ending in 300-00P indicates that it's the TMobile version.
My theory is that since this phone was bought when it wasn't exactly new on the market HTC had switched to the solderless screens which seem more modern?!?
I'm assuming that in terms of connection the digitisers that look like they will fit in terms of connection should work. I'm only worried about the dimensions of it since the casing of mine is smaller than the real TMobile version from what I can tell.
Since I can't find anything else on ebay I guess I'll order one of the TMobile ones and see if it fits. I'll look for a shop with return policy just in case.
Thanks for the help. If anybody has further suggestions I'd love to hear them.

Read carefully my previous post:
you don't have to be worry, the touchscreen, lcd and lcm are geometrically (length x width) identical!

Yupp, any LCM will fit on any model of HD2.
I wasn't sure which part was identical but if the digitizers are then what I ordered should do the trick. Digitizer should arrive this week so hopefully I'll have something to report about
edit: Digitizer arrived and fits perfectly. I guess my phone was some weird mutation. Solution is to just buy a digitizer with the correct connection, job done.
Oh and getting the right tape is a total *****. I had to take everything apart again because my tape wasn't strong enough!
I thought I'd post my findings and produce some cliffnotes on how I fixed my HD2.
Firstly, if you search youtube for "leo as" and "leo dis" you will find the official HTC videos on how to assemble and dis-assemble the HD2. They make it look easier than it is. Also, they don't separate the digitizer from the screen.
I ordered the tools to "dis" off ebay. Especially the T5 screwdriver was worth getting since it allowed me to find out which digitizer I need. I have a non TMobile version but needed the TM digitizer.
I found that using an old credit card type of card works very well for taking the phone apart. It can reach further into the phone and bends rather than breaking like some of the cheap tools from ebay.
Especially for separating the digitizer and screen it's great. I heated up the digitizer & lcd combo in the oven for a couple of minutes like the video advertised for taking the middle part of the phone apart (you'll see in the vid). Here comes the interesting part: Instead of sliding the card / tool all the way across the screen (between screen and digi), it's enough to just separate it around the edges. There is no glue or adhesive in the middle. It seems obvious now but I got lots of glue all over the LCD which was a bit** to clean.
Another tip that is worth repeating is getting the cheap double sided tape from ebay which is meant for Iphone digitizers (3M branded). I got three of them for £1 incl delivery. I used it to put the "middle" of the phone together. Screen and digi I did with cheap double sided tape which is working but I regret somewhat.
Another tip would be the whit cable (flash?) which goes on the bottom of the mainboard. I put it on top to start with. It's easy to mix up. Also it makes sense to put one end on before you put down the mainboard because that way you still have proper access.
Make sure you have good tape and be patient. I had crap tape and just slammed things together because I was so keen to see if the phone still works. I had to take it all apart again which almost broke the phone because it was coming apart in all sorts of places.
Overall it's like a big, fragile puzzle. I got the phone from a family member who had dropped it so all I had to get was the digitizer and tape. Now I have the best phone that ever lived
If anybody has questions, I feel like I know the hardware of the HD2 inside out.
I also took mine apart to replace the digitizer. I haven't got the new one yet though. I also watched the take apart vid on youtube. Unlike you I didn't disconnect the white wire from under the board. As a matter of fact, I left the other wires attached to the mainboard and just disconnected them from the GPS, camera and Bluetooth boards. At the end of the little channel that the wires are in, there was a little metal tab that held the wires in place. I just bent the tab up to remove the wires. Like you I used a piece of credit card to loosen the glued pieces.

Conductive tape for better WiFi/GPS?

Someone on the inspire forum used conductive tape on top of their antennas to boost signal dramatically! Anyone know the insides of a500 know if doing this would help us cuz wifi sucks..?
Sent from my Inspire 4G using Tapatalk
Funny, I am going to be making some conductive glue in the next day or so. I was wondering what I should do with the leftover. I will consider putting some on the antenna just for kicks. maybe I can coat some paper and extend it a bit. If anyone has a good idea of how to implement it I might give it a shot. I'm certainly not a radio engineer type person, so I really don't know if there are any guidelines that I should follow. Like whether or not this will need direct contact with the core wire, recommended length/shape to match frequency, what matters, what doesn't, would a graphite conductor even work, etc. Keep in mind that the resistance will increase with length on this adhesive. I can double coat it and help some but there is no way to avoid this without embedding a wire. I already get a good signal but there's always room for improvement. And I need to open my case to fix a dented corner. Lucky I didn't break the glass when I dropped it on the pavement...
And if anyone believes that this is a bad/goofy idea please say so. I'd rather know not to try something and why than to waste the time.
I was thinking that you could use small strips of aluminum tape (the kind that is used to seal furnace duct joints)
It is very sticky and you would have to use some Goo Gone on a Q-Tip to remove the adhesive from a small strip where the antenna contacts the tape.
I am going to try this once my plastic opening tool kit arrives from China.

I thought you sold your 500?
Considering the 500 uses the same hardware manufacturer for the antenna, I can say I get good Wifi in my flat. Even in the toilet.
GPS though, I need to be within 3 meters of a window, but that's understandable.

I was gonna sell it but a family member held onto it for $200 till I paid em back so I did n having fun again
But.. who ever wants to extend their radio reach with out buying new parts i will be trying conductive tape. My inspire can get WiFi anywhere in my house my a500 looses a bar 10 feet away from my Netgear CG3000D ..
Something needs to work.. I'm tired of laying in bed like a contortionist
