are cases necessary ?

I was messing around with my captivate and i was noticing it wasnt getting same amount of service that my old iphone 3g did. When i was in an area where service was quite sketchy , i would put it down and get two or three bars. When I picked it up in my hands it would drop for one bar or no service.
So the question is do we have to buy cases for these phones since service drops so much by having direct contact with the phone ?

no, cases are not necessary for reception.
If you are completely losing signal when its in your hands, you need to go to att and get a new sim card. If that doesnt work, have them replace your phone.
Note: if you are holding the phone by the bottom and losing bars but your signal is not dropping, this is perfectly normal. All phones do this to an extent since the antenna is located at the bottom. If you completely lose signal or drop calls because of it, you have a serious problem.

what i have noticed thats not just 3g reception its wifi too which is weird, i pick it up in my hand i lose a bar of wifi when i am in the same room as the cablemodem/router that doesnt seem right.
Usually when i pick up the phone it drops the three bars i hold it in my left hand usually. Another issue is i bought this phone thru amazon since it was 30 bucks cheaper for upgrade price, will att still allow for trade in or do i have to send back to amazon ?

I too have noticed this with my phone. Never really noticed until this iPhone 4 shiz came out. Guessing its par for the course.

areas where i used to get full bars i am not getting full anymore when i pick up the phone, it also happens with wifi which is really problematic.
Sitting in same room as router and cable modem and dropping below full wifi connection, and if i walk out of the room drops to one bar of wifi guess i will have to call att tomorrow and return my phone
Kind of off topic how thorougly do they check thier phones am i going to have to find an rom that has all the att bloatware stuff on it ?

This is a sad day really liked this phone , but appears i am going to have to return it , since this issue is a known issue so getting a new phone wont make these problems go away.
I was reading on another forum site that a lot of people having this same issue oh well i guess

wifi doesnt drop for me... thats really strange. in any case if you are only losing about 2 bars its normal and will happen with most phones. If you lose signal completly then its abnormal and ur phone/hardware is faulty.

yeah was reading about antennae issue on back part of phone where the battery cover is you cant touch it apparently. well i am going from 2 or 3 bars to zero bars pretty much.
An good example would be when i went into apple store which has 3g microcell tower in the store to hide the antennae problem with iphone 4 , i dont get full service and the iphones get full no matter how hard you grip them.
Going to give both samsung and att a call tomorrow morning to see what i can do i really dont think its fair to have to eat the upgrade and restock fee when phone cant perform normal functions

If you got the phone from amazon and are returning it, then it is free to return with no restocking fee. At least thats what they told me. All you gotta do is call the number for returns so u can get a return shipping label from them. Did you ask if you could exchange for another captivate at a local At&t Warranty Center?

I will be calling att and samsung tomorrow when i wake up to see what they have to say. As far as returning it to att, if its a known issue then an replacement phone will have the same possible issues.
So i did an little experiment to test 3g and wifi. I walked across the room, which has the modem and router, and stood by the door. got no 3g service in my hand, and the wifi dropped from full bars to just 1 bar of wifi in the same room.

I don't know what you guys are talking about. I can touch the phone any which way and the bar fluctuates by a single bar, if even that. I get more fluctuation walking around in my house then I do holding it. The only time I've ever noticed a significant drop in reception has been literally covering the phone front and back with both hands. Maybe you guys are just in poor reception areas. Before you completely discount the phone and send it back, instead of relying on the bars, look at the actual db signal in the settings.

I have looked at those i get an big fat zero. the other issue i have is my wifi goes from full to 1 bar by just moving to other side of the room thats not good at all.
I have been to areas of my town where i know there is full 3g service, and i get maybe two or three bars. i was thinking maybe an case would mask that particular issue since i am not directly touching the phone. The fact that i really like this phone i would just do the case thing if that were a solution

I will admit the area where i live doesn't have the best reception in the world, but when i place the phone on an table or sofa, i get -105 dbm and 4 asu. once i pick it up drops to 0 dbm and 0 asu quite odd.

Just to make sure, I removed my phone from it's case, and plastered my hands all over it. With a solid 3 bars, I touched sides, with two fingers all the way to a two handed deathgrip. Not only did I not get a degradation of bars, at one point I got a bar increase! I palmed the back, front, cradled it my hands, held it to my body. I didn't get any change in bars.
Maybe it's the band of cell phone signal in your area. I know that either the 1900mhz or 850mhz is better than the other in terms of penetrating power, so if your signal is going over the weaker one, that may be the issue.

I am just going to give samsung a call , when i actually use phone i am not touching the back of the phone. I have taken it into area where usually you should get full service and i dont get it if i hold it in my hand.
I also did an comparison with my old 3g iphone and the 3g was getting two to three more bars...
The other major issue is my wifi signal dropping from full to one bar in the same room of the router that shouldnt be happening

well its like i said, this signal issue that you few are having isnt that wide spread. go get a replacement sim, if that doesnt work then simply have ur carrier replace your phone. you should be within the 30 day trial period anyway... dont bother talking directly with samsung, getting a phone replacement from att would be quicker.

well the only issue with returning the phone i dindt buy it directly from att , got it thru amazon so returning to get a new one may be a bit problematic i think.

The iPhone's issue is different - it has an external antenna, and one finger in the wrong place rendered no signal - one finger bridging the gap between antennas - creating an electrical conductive circuit.
The Captivate (and all other phones) have internal antennas covered with plastic (the phone's case) - so the antenna is already covered.
Apple tried to deflect criticism by talking about "The grip of death" killing signal on other phones. While this is true, it is not what plagues the iphone - although it can. All phones will show signal drop if you wrap your hand (or some other signal blocking material) around the phone.
The Problem with trying to measure the signal drop, is that signal bars are not very accurate - you need to be in the phone menus where it shows you actual signal strength in DB - I don't think you will get this for WiFi though. Then of course there are all kinds of external interference issues - Microwave ovens, cordless phones, etc.
So, unless you measure this stuff in a controlled environment, like consumer reports did, where you can control the transmitter and all eliminate all external influences, then most observations are not including all environmental factors.
My phone works great, regardless of what the bars say.

well i have seen my phones service go from -105 dbm 4 asu to nothing when i picked up the phone. and then i would get the nice blue circle with line thru it.
I did an speed test also with phone while holding it and when putting it on an table , the times i would actually get no bars on my phone while holding i would get 1/3 the dl speed of when it was sitting on a table.
I will have to wait till tues to get an replacement phone and hopefully i wont have the same issues

so are you getting the replacement from att or amazon?

Free AT&T Microcell email? Question for Microcell users

Just got an email from AT&T saying that I'm eligible for a free 3G microcell - which supposedly will always give a set number of devices full service in the house it's placed in.
I normally get pretty good service in my house (even in Wisconsin), but that's not always the case everywhere I go.
At any rate, am I able to take this thing when I go places (say, to uni, which will happen once again in the fall) and use it where ever?
Thanks!

What's the email saying exactly and do you have a screenshot of that email? I work at att and don't know about that yet but different dept

Yes, you can take it anywhere that has high speed internet. But it needs to be registered to the location you are going to use it at, and it has to be placed near a a window to get GPS reception. If you take it from one place to another, you have to update the info on the website to reflect where it's located.
Also, it takes up to 90 minutes to activate when it's turned on.

I have one thing to add to your post which was great. It does need to be near a window to get GPS HOWEVER once it gets GPS it can be moved. I put mine near a window with a long cord (router isnt near window at all) and it locked on GPS. I then unplugged it and moved it next to my router and it powered back on and locked GPS as it did prior. That's a little tip if you don't have a window near where your router is installed.

if you already have good service, 2 bars plus you dont need/want it; it will just make your phone go crazy.

It doesn't always retain it's GPS info if it's unplugged. If you dont' have a window nearby, you are better off running a long cat5 and power cord to it, and then moving it without unplugging it.
Or, you can buy an external antenna for like $25 that gives you a 25 foot cord.

I imagine they will give you the microcell if you agree to the unlimited service they try to sell you with it. I can't remember exactly, but it was something like $25/month for all calls made through the microcell, and they don't come off of your minutes. I've got one at home because I live in a dead area and rarely have reception unless I step outside my house, plus I don't live in a 3G area anyway. Problem is, when I walk into my house, it won't automatically switch over to the microcell unless it loses the signal from the tower. Works pretty good in the house, though, but my phone will lose connection to it intermittently with it for unknown reasons. Not a perfect solution, but it's better than missing all of my calls when I'm home.

I dont know if anyone else has experienced this. I got a microcell last week and use it with an unlocked samsung vibrant. My apartment does not get very good reception at all (rarely even get one bar) and when connected to the microcell it chews through my battery. Previously, even with poor reception, I would go through 1-2% of the battery per hour with use. When connected to the microcell, i go through 4-6% of battery per hour without any use at all. I do not know a great deal about the microcell where this could be a firmware thing or it could be that I am using an unlocked phone from another carrier, but just something to watch for.

I have one of these. If you use it, don't expect H+ speeds off of it. You get 3G speeds on data. And if you don't have a good broadband connection, voice can get choppy. But there is a benefit to having and using it. For $20 a month (I think), you can get unlimited family domestic calls on it to any phone regardless of whether it is a land line or cell phone. But I have the $30 unlimited texting and cell phone calls now on my family plan, and make so few calls to land-lines, that I no longer use that service.

lol how weird, i work for an at&t shop and i just got a call by someone questioning an email they got about a free microcell.. i was browsing thru xda at the time and was on this thread, crazy..
i have one at my house, its cool if you really have absolutely no service where you live.. the only down side to this device is; if you are currently connected to the microcell and are in a call, if you leave your house the call will drop as you are leaving the microcell and reconnecting to the normal cell towers..
if you are never "in-call" while moving in and out of the area of your house than you wont notice this and it will be a cool device for you to have.

Don't take your MicroCell to the Grocery store!?!? Step away from the cell phone...

What a huge inconvenience it would be to travel with this thing.. maybe if you're going to be somewhere for over a week (Still wouldn't take it with me) . but if you're just going to a buddies house for the afternoon... please leave your MicroCell behind.... lol
For some reason, I can't download while on Mobile Data and connected to the MicroCell. Upload appears to be fine, but as far as browsing the net at home when im too lazy to open my lap top.. No Bueno... Wifi still works so it really just irritating more than anything.

Mine seems to be hit and miss for calls. Sound great when they come through but seem to drop.after 10 min or so. Other than that I have no issues with it. Just that data speeds suck but when I'm at home.WiFi works just fine for that

how do you get it to stay locked on to gps? ive taken mine outside multiple times and after a while it locks on to the location, but after i unplug it and place it inside it loses all the information
thanks

I have absolutely NO Service where I live and too have a Microcell- I have noticed as previously mentioned if while talking inside and then going outside- the call will drop.
Also there are some moments where I will receive a voicemail notification & the phone never rang. Other times- I am not connected so I put the phone in airplane mode for a few seconds and then back to reconnect to the Microcell.
The Microcell definitely improved the ability to talk to others when before I had to go outside to get some bars. It's hot outside- it gets old having to talk to anyone- outside- so I am grateful AT&T hooked me up with a FREE Microcell.

The rule to the Mcell is they drop calls going from micro to macro. Apparently its not a smooth transition like tower to tower..also speeds are veal but that's what you get limited speed but increases signal

Ok, for those without the DEATH GRIP WIFI ISSUE. PLEASE POST

a video. Im not calling yall liars, but ive had 3, and all have the issue so I just dont see how others dont. Unless its the routers, and yours is way better than mine cause mines junk, but never had issues on other phones.
Anyways, please post a video showing in another room from your router, covering the top landscape style and take a video showing the bars. I dont care if they drop some, Those that say it dont vanish can I please see a video. I JUST DONT GET IT.
Thanks, p.s. I got my 4th sensation on the Way. I want this phone but dont want the wifi issue cause i use wifi 90%of the time.

Don't have another video camera, so you'll just have to trust me, or trust the videos that are posted on YouTube that show it working. I'm in another room, landscape, hands wrapped around the phone every which way, the wifi connection never drops. I don't have a case on the phone. Using Wifi Analyzer I do get about a 20-25dB drop in signal, but it's still plenty strong enough to stay connected and not drop data.
It's more likely something about differences in routers than the phone. Maybe signal strength, or g versus n, or the specific channels being used. Not saying there are no bad phones, but if you try 4 phones and they all do it then it's probably related to something about the router.

I've not got a video but I don't hold my phone when using it in landscape (I rarely use landscape at all tbh). I put it on my lap so don't have the issue

please please post a video someone. This is my only issue. If its my router and I need a N ill buy one, but I need a video of someone going to the router, then watching them walk to the end of the house in the room and do it. If it does not kill your wifi I will be sold and figure out why mine is..
Do you have a N router?
Is it just G?
This is serious and Ive only seen videos of them effected and experienced the same.

Ok so I took my case off and had to wrap my hand completely over the top end of the phone to show a difference, but it did drop two bars ,now since ill never hold my phone in that manner this will never be a problem for me , so I would say that the case makes a diff and its definately there , I really don't like holding it in landscape mode ever , i rarely do

For ref, I have a G router (a rebranded Thomson)

but you said you dont hold your phone in landscape. I for one play online FPS games in landscape and need it.
Can you test in landscape? since you dont go in landscape? or did you already and have no issue?
please post a video. If yours is fine there are good ones and ill find it. If not im trading back for my g2x today because that

so far Im getting. I have no wifi issue cause I never cover it?
well if you do hold your phone in landscape and have no issues, then please post a video. In portrait im golden, but when I landscape it completely depletes.

Here's a video that shows signal drop but no disconnect when the wifi signal is strong.
http://www.youtube.com/watch?v=j64GKuuczoE
This is just what mine looks like. Drop in signal, no disconnect.
Notice the other low signal wifi's in this vid do drop away. The same guy also posted a video showing a total drop in connection if the wifi signal is relatively low at it's peak. So, at least part of the reported problems could be due to a relatively low max signal.
If you don't have Wifi Analyzer get it and post a vid so we can see what's going on.

I will make you a video the second I get off work at 4pm. I will show the router on video, then walk up stairs, hold the phone in landscape and show that none of my bars disappear. Do I get anything in return or do I just prove I'm not a liar? I am really not trying to knock anyone here but I find it odd that we can all buy top of the line phones but still use shifty routers. A goog router will make your life a lot better for a fraction of the cost for your phone. I suggest everyone get into the year 2011 and atleast by a N router, if not a dual band N router.

Ok that. WEll, hes next to the router, so thats why the wifi dont die, but I garuntee that if he goes in another room it will die. WE need to see where his router is before we judge if his connection never drops. I bet hes in the same room.
WIfi analyzer vs my vibrant is amazing. Vibrant perfect barely loses db. Now the sensation loses 20 no problem. So in a room with wifi it will be connected, but in a room with less signal, you will cover the signal and kill it. It shouldnt be like that.

You've identified why people are reporting different experiences, which is exactly what I said. If the signal is strong then the connection won't drop. If it's weak enough at max then it will drop.
The loss of about 20-25dB by holding the phone certain ways is known, and isn't likely to vary much be getting your 4th or 5th Sensation. You could try holding it differently, or maybe some types of cases (with or without PT ) may help. Or you can get a router with a stronger signal.
Whether or when HTC will do anything to fix or improve the issue remains to be seen.

Your right, you shouldn't need to hold it differently to hold a WiFi signal. Do you still want me to make a video showing that non of my bars drop while on a different floor from my router.

Please, I would love that... Cause if so I just need a stronget router even though my other phones work fine sitting on them..

I live in a small apartment and I have a good router (bought it like a month ago) even when I'm standing directly in front of it, the signal will drop (I watch the meter in wifi analyzer drop) If I'm in another room it drops even more. I have my phone set for max wifi performance too. One night I really noticed it while streaming a video from my computer via splashtop. Every time I held it a certain way the video would actually stutter. I wonder if the people experiencing it have some kind of grounding problem with the phone. It's not a huge issue for me because it never fully drops and when I hold it in landscape mode I just make sure My hand doesnt cover all three anntena holes on the back. It seems when your hand is in contact and covers all 3 that it drops. I should be getting another sensation on friday. I hope 1. the wifi drop isnt as bad 2. That I get the better sharp screen

I have one coming soon as well. Ordered today. Will see how it goes. I just don't think I should have to get a new router when my others phones work great.. I'd say grounding causeof if I put tp between my phone and case I can't get it to drop... Move the 2 layers of pt and it goes away.

Sounds like you should just ditch the Sensation; some feedback from my experience; I have the Rubberized case on mine and at work with the case I get about 1-2 bars of WIFI; without I get almost full.
Turning it landscape also kills the connection with case and drops to 1 bar without case so thats pretty ****ty although I don't use my phone landscape or really play games on it but for people who do I could imagine that sucking pretty hard.
Was gonna do a vid but I don't think it's really necessary. If you have a strong signal (ie sitting next to the router) your likely not going to notice anything at all; if your on a medium signal it's likely you will lose bars or total connection.
Not really sure what video proof is going to do for you however as it really doesn't matter what others are experiencing in this case outside of their verbal explanation.

I have to agree, this issue is annoying. In my house I have 2 MT4G's a Thunderbolt and the Sensation. None of them drop wifi signal like the sensation does.. I don't use a case and sitting 3 feet from the router I'm ok, even turning around facing away from the router at 3 feet I'm ok but it does drop a couple of bars. In other rooms I have full bars but if I cover or hold in landscape as has been shown I loose all or down to 1 bar and most of the time it will disconnect.
Not sure what type of router mine is as it is from AT&T UVERSE.

Here is my video 3 rooms away from my router I drop a little but no disconnect.

[Q] found a serious flaw with radio hardware and shipped ROM downloading consistency!

Hi all, please welcome me whom had bought the Optimus 3d just 2 days ago. I love this phone. Please do let me welcome you all to talk about a flaw, which I've found out right away with the new phone since 2 days ago! I've been with some others Android phones, so, I should say I've had good experience with Androids.
I realized that Optimus 3D has some kinda hardware Radio receiver flaw (I really don't know what should I really call it) similar to the famous iPhone 4 dilemma in the beginning. I found out that the "Radio receiver" is located somewhere at the bottom of the phone, where our hands most often holding the phone with. The hand will block out the signals and the signal bar will be reduced by a lot as much as to zero (if the signal strength itself is not strong in the 1st place!) Try find this yourself, have some experience by holding the phone at the bottom and let go and holding the phone and again let go, keep trying this you should see the signal strength that will drop and rise and drop and rise again. Or is this only my phone? But I've never experience this phenomenal with other Android phones!
Also, I don't know this has the directly link to the downloading issue or whenever browsing nets, the network data will drop very very often. I hardly got successful downloads from the market without few retries. Thank god at least at the moment I can temporarily fix it by turning off and on again with the data enabling shortcut in the pull down menu.
Please help me here and advice! Very much appreciated!

Since the famous iPhone 4 drama for a lot of phones these stories pop up once in a while. I know lots of people furiously believed the Samsung Galaxy S had the exact same problem but after a week or so nobody ever talked about it anymore.
I myself have absolutely no problem whatsoever with the signal, not even when I completely cover the entire phone with my hands leaving just a small spot to read the signal it never drops, not by one bar. I've never had a single download dropped with either 3G or wifi and I've downloaded my share of stuff from the market and other places.
I've tested this with my T-Mobile simcard (which has pretty horrible coverage here) and with my Vodafone simcard (which has great reception) and with both simcards the signal strength stays exactly the same according to the bars. Even when I go to the settings the dBm and asu values stay exactly the same, no matter how long and how bad I cover the phone.
So far you're the first and only person I've read about having these issues so I think it just could be an isolated incident, although that would be bad for you as that would mean you could have a defective phone

This problem is not something new and is not related with O3D.
All the phones have the same issue.
It is normal that if put your hand on the antenna the reception will drop.
The radio waves just work like this.
However the atenuation from your hand is most accentuated on higher frequencies like 2100Mhz.
On every phone even on the oldest phone with external antenna you will meet this phenomenon.

The difference between 4 bars and 1 bar is only around 10dBm which really isnt that massive a drop at all. Now that you've pointed this out i do see that the signal strength varies a little depending on how you hold the phone but its not enough to panic about i don't think. The iphone 4 problem was significantly greater in that the iss was that a user's hand would electeically short the mobile network antenna to the bluetooth and wifi antenna causing a total loss of signal. While 10dBm or so is a definite dip in signal strength, it's an acceptable level of attenuation and i dont see it causing any real world day to day network problems that you wouldn't experience with any other high end smartphone.
My workplace is in a giant tin hut of an industrial unit (read: faraday cage) and today while i had this phone there for the first time i saw no noticeable network coverage problems. The behaviour was as far as i can tell exactly tue same as my motorola milestone from which i upgraded.

As stated all phones can lose a bit of the reception when it's in your hand depending on how you hold it, the reason Iphone4 was such a big deal was that it was extremly sensitive when it came to left-handed people and they had a real problem with their antenna being totally blocked when holding the phone normally when speaking in it.
Later on media and uninformed people started fueling the flames as soon as they saw a bar drop when picking up the phone, radio waves are not magical rays or tachyons that can move though matter without interacting with it.

thanks for all the replies. Believe me or not, this is the 1st phone I realize this issue and it is so obvious, the bad news is, it is really bad for me that the antenna is located at the bottom, probably most others phones I've owned were at the top as a result i didn't got any problem before.
And another issue, I'm pretty stucked with the shipped rom now, really hope to see custom roms soon. I'm at the moment totally freak out with the inconsistent of data and the wifi, it keeps failing me, this really freak me off, what the hell is happening to me with this phone! I've never ever got any dropped data or wifi connections before. Arggghhhh!!!!!!!!!!!

I have no signal drop out no matter what hand positioning i use..

I'm in a very poor reception area. I do notice hand over phone a drop from 1 bar to none. Still not a red cross to indicate no signal but a drop of 1 bar all the same.

Just tested it.
Signal drops from 4 bars to 3 (1-2 in awkward positions) when hand-held. Not an real-life-usage impact though...

Thanks for all the test replies to support my findings. OK, now, I've realized that the hand holding issue has no direct impact to data drops. And the data drop is entirely due to the time issue which it does not lock down the data connection when swithcing data modes. And at the moment it can beasily over come to turn off with the data button in the pull down menu. I'm not sure though when in the situation when the signal strenght was so low, by holding with hands will give an direct effect of data drop or not. Will observe that

Wifi Issues

When I move into my room, my laptop gets 90%-100% signal strength from my Wifi, my phone however randomly looses signal completely and especially when I take up the phone to use it. It's very frustrating. Plus when I'm on 3G, it constantly switches from 3G to H too.

The 3g H switching is normal if you are on tmo us and running the eu roms and has been discussed quite a bit
not sure what you mean by losing signal, but i get diff bars diff places in my house. never lose the whole connection as in not being able to dl or browse web
did you run speed tests at these diff locations in house

I think you misunderstood his post. His primary problem is that the wifi on his phone doesn't come close to the signal strength his laptop has when in the same room.
The secondary problem was the 3g/4g switching.
OP -- I have no idea what to tell you.

no, i understood. just saying my phone wifi bars fluctuate even if my laptop has good signal. may just be the way they both display strength readings
i think op should run speed tests btw the two at same time. however both devices are splitting signal so may not be as good as only one running at a time
his speeds may be fine even though bars don't show it

I'm in Jamaica, no T-mobile. I'm not sure if I'm running an EU rom. My problem is that I loose connectivity to Wifi totally randomly in my room with even little motion. I mentioned my laptop for reference... it's like there's poor signal in my room. The phone'll just bit sitting on my bed, I hear an alert and pick up the phone to realize I've lost Wifi.
Speed is not the problem, I've been able to run a speed test to confirm I get the speed I'm supposed to get. Other times though, the speed test could not complete because I moved a little and lost connectivity.

Make sure that your SIM access cover is snapped in place.
It happened to me with the WiFi signal - The phone was losing signal, and had low signal 1 foot away from the router.
I 'pinched' the top-right corner of the access cover (thumb on the glass, index finger on the back cover) - I heard a 'click' and suddenly my WiFi was at full strength. I believe that the WiFi antenna is not connected unless it snaps together.

ok, not sure what to suggest. you could try turning airplane mode on and of and see if that helps
maybe router settings with the phone if you always had the issue
under settings/wifi/ tap on wifi then the 3 dot menu--Advanced. See if Keep Wi-Fi on during Sleep is Always. If not tap on it and change to Always
Also at bottom of Advanced menu is a DLNA setting, you could toggle that
barring that or someone else's ideas--maybe hardware and needs replaced

Try turning on Best Wifi Performance in Wifi, advanced settings.

Turning on best WiFi performance totally killed my battery life, but that may just be me.
If you're losing signal on one device but not another, I'd recommend changing the channel on your router. Interference on certain channels can cause weird issues with some devices. There are apps on the market that will show you which channels are congested in your area.

Hmmm... I'll try that. So far turning on DLNA and Best Performance hasn't made any difference. I'll try changing the channel when I get home later and post the results. I REALLY hope h/w is not the problem.. it's gonna be a hassle sending this back.

It might be worth gently cleaning the contacts exposed when you remove the SIM access panel. As District noted, good contact is necessary for wifi (and probably other features). Dust or a fingerprint may be problematic.

Anything to bear in mind when trying to clean it or adjust it? I'm really paranoid I'll mess it up.

make sure you use electrical cleaner
radio shack sells it, comes in spray can
if you haven't had sim card out or phone long, probably not issue. but, worth try
if you have another router, you can always try that

Nothing seems to work... I'm using channel 11 @ home which doesn't seem to be crowded. I have the same issue @ work with our router. I've been having this problem from I got the phone last week. This is after I initially removed the back cover to first insert my SIM.
I'm going to try and see if I can secure a cleaner... I tried blowing on it mean time. Also turned on DLNA and best wifi performance and all.

DLNA auto-IP setting worked for me.
Hi OP,
I had the exact same wifi issues on my One S. I tried the router at work, the router at home and my mates router with the same results.
Mine seems to work now, with no disconnections or manually connections. What seems to have worked for me -- Wifi - Advanced menu -- DLNA auto-IP setting - toggle on. Then restart, making sure the setting is still set after reboot. Seems to have fixed my wifi issues.
HTH.
Darren.
