The Samsung 4G Naked: Side by Side in the Nude with the Vibrant

Good Evening,
After taking the 4G apart several times I decided I would take pictures to highlight the few differences. Some noticeable differences:
1) antenna placement on the board, matching contact placement different on the back housing underside
2) the connector for the headset is different and the ribbon is labeled T959V (model # for the 4G)
3) less memory which can be seen thru the software
4) the GPS still sucks and does not work on this one
5) maybe I received a defective unit but there is an overheating issue. the 4G uses 200ma more than the vibrant but maybe the phone or the charger is defective as it keeps overheating and with time charging seems to be more of an issue/concern. software confirms this with error message.
Enjoy the pics.

Thanks and I hope this helps satisfy some curiosity. In my opinion, from owning both of them, not worth the upgrade at all. The 4G is going back to T-Mo.

Wow Samsung.. a new model and you STILL can't get the GPS right? This is absurd

Pretty neat to see them both....

my gps works great... was showing 11ft accuracy on gpstest tonight.

Can you confirm that the camera has the same plug connector as the vibrant ?

Yes - confirmed - camera has the same plug connector. I swapped various parts back & forth to test things out (actually using them, took pictures, etc.) and the only things that are not compatible are the headset plug connector; I guess that is why it is the only part inside that has T959V labeled on the ribbon itself, and the back housing - the antenna contacts receptor(?) on the underside, since one of them was moved to the top of the board, which is also labeled T959V instead of i9000 as it is on the Vibrant.

My gps works great. Maybe its just your phone?

where is the modem at? is it interchangable? like could i buy one online like the ffc? then i would esentually have a vibrant 4g?

The modem is one of the black chips soldered onto the board. So no I don't think it would be that easy even if you have those robot precise soldering skills. I will upload a picture that shows the chips and identifies them on the Vibrant (same layout as the 4G but obviously the modem is different on the 4G. Then you have to consider that the extra 20% juice this phone consumes (1000ma on the 4G vs 800ma on the Vibrant) is to power the new modem. So even if you did have the soldering skills, then you might have a power problem.

Yes, it is a possibility. The phone keeps overheating as well when charging, it gets extremely hot. I think this may be a defective unit I received.

i got my 4g and so far no problems with battery or GPS... gps was the first thing i tried and it worked great. im guess some of these crappy phones are slipping through Quality Assurance on the assembly line...

You are totally right. You would think after the GPS mess & outrage with the Vibrant that they would be more careful this second time around. Apparently they did not listen or learn. It really makes me consider going for the LG Optimus 2X instead of the S2. I really want to get the S2 but these problems keep worrying me. It is like loving someone but they keep beating you up, do you get out of the relationship or keep hoping it gets better? Hmmm....

my gps works alright, sometimes it's a little wonky but nothing horribly concerning. i haven't gotten the overheating issue once although my battery is kind of sad.. i've rooted it and used setcpu to underclock when idle but still just short battery life.
i have noticed, however, that i have a green tint to my screen. noticed when taking photos that skin tones are off, then i email it to myself and check on other phones/computers and sure enough, it's just my 4g screen that seems to be tinted green a little. anyone else notice this or is it just me?

Hmm that sucks, if you are going to keep it, that is a problem I would not want to have, try get it exchanged. Thanks for letting us know about your problem.
Maybe someone has a solution and can offer some advice for the green tint?

This thread alone just convinced me that there is no way I would upgrade from the vibrant to this. What a let down. I considered getting it at first but thankfully realized they are just the same phone.

Moved to general as not android development

My friend and I both got 4Gs' at the same time. My gps fixed within 2 meters in my home, his running side by side took a long time to aquire. We rebooted his, gps took a long time to aquire but after 2 min, it did, but was within 9 meters of same location.

I wanna know...
I see the GPS is an issues. But I wanna know from yall that have the SGS 4G, is this the phone to buy right now on Tmobile or go a different route?
Im still rockin a Touch Pro 2. Contract about to end soon. I was lookin at the myTouch4G but the SGS 4G has better looking radios. Where the myTouch only has the 14.4 stuff.
What's yalls thought on it?

I have used both and they are both good phones. The decision for me was made by the screen on the GS4G, the Super AMOLED just looks so much better to me. The MT4G is a more solid feeling phone and it is plenty fast (processing wise). The GS4G is noticeably faster on the 4G network and I also get faster speeds while on WiFi, not sure why but I will take it! Coming from the TouchPro 2 you will be happy with either, I just prefer the GS4G.

The HTC Sensation Death Grip - GSMArena

Is this the reason why people seem to be suffering with poor signal? Not good news
HTC Sensation suffers from death grip, iPhone 4 caught snickering
But then again nobody I know carries the phone around flat in the palm of their hand, so probably just another overreaction from the HTC Haters

just saw this at gsmarena too... can anyone do a re-test if this is true? i want to get an htc phone but these things really bother me.. please confirm guys

Just about every phone I've ever had had a death grip issue, including the Vibrant and the MT4G. Since the phones had to be held in a particularly unorthodox manner to experience this, it was a non-issue.

I agree, if you look at the video of the Bluetooth music, when holding the phone in the normal position it works perfectly.

Yep. Just people overreacting and trying to make news.

I'd love to see a video of a phone that can't be made to suffer some signal loss by holding it in a certain way.
The key question is does it suffer significant loss by holding it in a normal manner. More practically do you get wifi, call or GPS drops when using the phone normally. Show me that video and I'll care.

I don't see this as an issue since how often or why do would you need to put a death grip on your phone

Tried to replicate these issues, cannot. The initial signals must be too weak to start with, so disappear completely - or, the whole thing is a fake.....?
Bluetooth is shorter range anyway, isn't that the point, it's meant to be low power.
My Sensation wifi reception isn't the greatest but I have no issue with it, however I hold the phone
Tbh I am surprised at a site like gsmarena posting 'sensational' claims..... without knowing the whole story.

In 2 words: bull ****.
Really, I can't understand why people are searching those issues which are not issues at all O-o
I mean, every phone does suffer from signal drops and all that kind of things, but well.. it really depends in which position.
If you look in the video, the phone works perfectly when holding it normally.. just when you hold it like I dont know what ( who will hold it like this?) the signal drops.
So I think there is nothing to worry about..

I think that this is a valid issue since when you browse the internet and hold the phone horizontally for landscape viewing then this might cause the wifi signal to drop. I have read this issue also on the HTC Desire S. I went to the store to try and its really true that when you hold it horizontally, the wifi signal would drop. So i guess that this is also happening on the HTC Sensation.

Isn't GSM arenas phone missing a contact?
slash gears sensation has an extra contact thus I'm assuming equals better reception.

It's because SlashGear has the US version while GSMArena has the UK one.

Yeah, apparently the 4G model has an extra contact point.

The T-Mobile version needs another contact because of 1700 MHz band (not sure, I'm just guessing)

if the sensation is anything like the HD2, the GSM Antenna is in the lower part. On top are the Wifi+BT (same Antenna) and the GPS. Total of three antennas.
Also, the HD2 had the same arrangment were the back cover (plastic)had all the antennas & they were connected by similar conacts. The difference simply is that with the sensation the cover comes out when removing the battery while the HD2 had the plastic back fixed. So if there is a problem with this design we should have noticed it in the HD2 first.
Another thing, the BT streaming sample done, as per swedish source was done at 6m distance. which kinda long for purpose of bluetooth!!

Does that mean the Sensation's Wifi, Bluetooth, GPS, Radios won't work if the back cover is removed? That would be too bad coz my HD2 works fine even if the battery is exposed..

Today I found out that I am also suffering with my sensation.
It is absolutely no bull****.
This is my third HTC, I have next to my Sensation a HD2.
With my HD2 the deathgrip was only a problem when i cover the hole with my top hand, i never normaly do that so it wasn't a problem.
But with my sensation its a much bigger problem.
If i hold him in my right hand, there is no problem.
if i hold him in my left hand and touch with my right finger then you see that he is losing signal.
if i hold him in landscape mode then almost all my wifi signal is gone.
If i hold him in my right hand and tick with my right finger on the top of the sensation, the wifi wignal drops down.
And the biggest problem is that he loses the wifi signal and then he is searching again for wifi.
I have never tested Bluetooth, and i have 3 antenna points in the cover.
maybe i will make a video later.
and sorry for my bad english, google translate Helps me

because of the bad range.

Hard to belive ppl are not thinking this is a problem.
That Position is MUCH more common then the Iphone 4 death grip... Also the issue is much more prominent on the Sensation then on the Iphone 4.
EDIT: I can NOT belive how accepting ppl are of the HTC sensations faults. It REALLY saddens me.
PPl.. there is no need to Defend HTC with your life. They are one Company. We should be choosing best company not being fan boys. Every1 should be able to recognize the problems phone have.

Antenna location, where exactly is it?

Is it on the cover? On the phone body itself?
Anyone know the exact location of where it's located?
Sent from my HTC Sensation 4G using XDA Premium App

Top and Bottom of the back cover

Thanks...I'm assuming that the main antenna is toward the bottom of the phone since people have been complaining about the death grip issue?
If the main antenna was indeed on the very top then the death grip would be irrelevant since the top never gets covered by your hand. When holding the phone, the hand usually grips the middle-bottom portion of the phone.
Pretty interesting....hhmm..

Not true. It's touching or covering the top area of the phone that causes the wifi problem. It typically occurs in landscape mode where the left hand is holding the top back part of the phone. You can see vids on YouTube showing it. It's also been shown just by touching the very top edge, or specific spots on the top side of the back.

I was referring to specifically to the cell phone signal. As mentioned, I have reason to believe that the bottom antenna may be the main voice/web (3g/4g) signal? Which may be responsible for the death grip?
Anyhow, I just wanted clarification as to what the four gold points are specifically responsible for.
So let's start with the bottom. That may be the voice/web antenna?
Upper right (two gold contacts) wifi and gps?
Upper left (one gold point) for voice?

Death grip people are talking about is wifi, not mobile network. I don't have problems with mobile network signal, but I have BIG problems with wifi.
Top plastic (where the camera is): wifi & BT antenna
Bottom plastic: mobile network antenna
Oh, and there is another contact on T-Mobile version (top left) but I'm not sure what it's for.

The top contact is for the additional antenna that gives the HTC Sensation 4G receive diversity AKA less of a death grip effect when using the phone in portrait mode. It's an additional antenna

A is the GPS antenna.
B is the WiFi/Bluetooth antenna. (I agree, tested pins)
C is the "Diversity" antenna (rx only). (Can't be, I just tested and got GPS signal to be stronger on these pins)
D/E is the GSM/WCDMA antenna.

Actually A is the RX diversity antenna, and I'm pretty sure the WiFi and BT antenna is the one below the camera opening. Not sure though
The main cellular antenna is definitely at the bottom.

A is GPS and Diversity is below the camera per the FCC filing attached here:
My current theory (since the XE lacks antenna "A") is that if the filing photo is correct, the Diversity antenna may act a backup for the GPS antenna. Or the filing could be wrong and GPS/diversity are switched, in which case the XE doesn't have a Diversity antenna.

That's what I was thinking, the international Sensation doesn't have the contact there (A) and the Sensation 4G is the one with RX Diversity. It wouldn't make a whole lot of sense for them to completely switch the antenna spots around. It could be possible tho

This is the back of a UK Vodafone sensation, i.e. minus the 4G.
Sorry for the ****e quality, I didn't realise it was so bad until I's transferred it to the PC.

I have the HTC Sensation 4G (z710a from Bell) and it does not have the A-pin.
Nonetheless all connections (BT, Wi-Fi, GPS, mobile network) are working great!
As seen on the picture, the mentioned A-pin is missing on both covers. The left one is what I have for daily use and the right one came with my phone.
I have a second white cover and the pin is missing, too.

Tear down pics of the Verizons S3

Well not sure if there is a thread like this yet, but I figured I'd post it up in case anyone wants to see them
The actual reason I had yo do this was because today I went to take a picture of my little kid (he's ² months) in his bathtub and he kicked my s3 out of my hand, and into his bathtub. So I pulled it apart to dry it out'

Is there a warrenty sticker anywhere on it? I noticed there isnt one covering one of the screws like I read about. I did notice there are what looks like white stickers covering some holes. I was going to take the screws and back under cover off just to have a look around but I was afraid they have some hidden shenanigans that would void my warrenty.

Just jizzed in my pants..nngghhfnfnfnfkdkd

nope no warranty stickers.
those little white circle stickers on the back cover, are covers for the antenna connections (similar to what you see on a wireless laptop card.)
& yes the phone is working excellent.
in regards to the little antenna connectors, i actually separated my RFID chip & antenna from my works ID (we have HID/RFID badges to let us in & out of the building)
I soldered a laptop antenna connector to the RFID antenna, end (allowing both ends of the RFID antenna to connect to the chip, but then on the 1 end there is a off shot with the wireless antenna connector) & i connected that to one of the antenna points on the phone.
before doing this i only received 1 bar with wifi in the farthest part of my back yard. not i get 2 , also i can hold my phone 4-8 inches from the works badge reader & it read (so its range increased as well) normally i would have to lay my badge on it & move it around a little bit
so win win 2 birds with 1 bullet (thats a inside joke that maybe a few will know )
i wish i was able to put the NFC chip in emulate mode so i could just emulate the work badge, but this solution turned out to be better (for now)

Good job

Obviously the nfc chip is in the battery lol I just bought a 4500mah extended battery. I wonder if there outs anyway to swap the NFC antenna to the new battery? If anyone knows , I would be happy to test it out. I guess I will have too Google it to see the possibilities!

Anyone have information on antenna layout?

I've been having reception issues for almost two months, and i've ruled out software and SIM issues, which leads me to believe it's a hardware issue. Wi-Fi works with no problem, so i suspect it's the GSM/3G antenna that is failing. However, i have no way of knowing where it is. I know there are antennas on the two plastic pieces in the back, and i know that removing the top cover (where the microSIM is) kills Wi-Fi. anyone know where the GSM/3G antennas are?

Others may disagree, but every phone I've ever owned had the 3g antenna in the bottom for regulatory emissions reasons.

Its at the bottom, guess the antenna actually IS the removable cover. Images and some FCC stuff here: http://www.anandtech.com/show/5868/htc-one-s-review-international-and-tmobile/7

There is an anntena on the bottom cover

Excellent, thanks

I've been having reception issues for almost two months, and i've ruled out software and SIM issues, which leads me to believe it's a hardware issue. Wi-Fi works with no problem, so i suspect it's the GSM/3G antenna that is failing. However, i have no way of knowing where it is. I know there are antennas on the two plastic pieces in the back, and i know that removing the top cover (where the microSIM is) kills Wi-Fi. anyone know where the GSM/3G antennas are?

Hey, i'm also having this issue, for almost two months now.
Do you have any news, were you able to fix it?

I'm waiting for the tools i bought from Dealextreme to arrive. Once those show up i'll have more news

Well, i got the dools, opened the bottom panel and everything looked to be in order... pins were there, i bent the outwards a bit to make sure they were touching the antennas, but the problem persists

Damn, maybe the cables that connect the antenna to the motherboard are loose?
The connector, i mean

I'm not comfortable with it too. I'm pretty sure our problem are related somehow, might even be the same.
Because I live in Brazil, its impossible for me to get official support for the One S here, since the phone wasn't released in Brazil.
If you get any news please let me know, ill look into it too, and if I found something I willl let you know.

i live in chile, so i don't have official support either. I'll make sure to let you know if i can fix it.

I was reading some of your posts about this issue, and i saw that you dropped your phone from knee high.
Well, that happened to me aswell, the same day i dropped the phone from my table i started having issues with the antenna.
Knowing this, i can say for sure that this is a hardware issue, and not software related.
I also saw this video on youtube http://www.youtube.com/watch?v=b0jGY2N2h1U
On the comments there's a guy saying that he fixed his antenna issues by using this tutorial.
I'm trying to contact him, to check what the issue was, and how he resolved it.
I'll post here if i find anything new.

Just so you know, i took the phone to a repair center (not HTC specific, but seemed pretty good) and they told me it's a problem with the PCB or chips, since the phone wouldn't pick up a signal even with an external antenna
