[Q] Differences in "Sentation 4G" and "Sensation XE w/Beats" back covers?
A month or so ago, I dropped my Sensation 4G and scuffed up the case (the fact that the battery cover is the case is why I love this phone!) So a couple weeks ago I ordered a rear cover for the Sensation XE with Beats by Dre (because it looks cool). After the purchase, I noticed the auction said "Not compatible with T-Mobile Sensation 4G". Damn, so I looked at the photo, and the XE case is missing a contact point to the left of the speaker grille. I figured I'd wait it out, worst-case I could disassemble and re-glue the top plastic pad from the 4G.
So I got the case today and put it on. To my surprise, everything seems to work. I get the normal 4G HSDPA signal and data speeds for my area, and Bluetooth, GPS and WiFi work just fine with identical levels to the 4G case.
So my question is: What antenna does that contact point contain? all other contact points are identical, and I can't see any immediate difference. Has anyone a clue? I thought it might be the AWS band, but I've no way to readily test for UMTS signal (my home area is all HSDPA). Below is a comparison photo, the XE case on the left, the 4G case on the right. Note the missing contact point to the left of the speaker grille (the only functional difference).
Edit: Apparently the Sensation XE does have AWS. Curiouser and curiouser...
Very cool, if everything is working fine I'm going to buy one myself.
How much are they?

I still can't post a link, but if you go to eBay and search "ORIGINAL OEM HTC SENSATION XE BEATS AUDIO BLACK REAR BACK DOOR BATTERY COVER" you'll find it. It's AU$39.99, ships from Singapore (mine actually came Registered Mail).
According to the FCC filing for the Sensation 4G, thats the GPS receive antenna contact (see attachment).
Very interesting indeed since you say GPS is working the same. I'm only hypothesizing here, but you could try turning off your network(s) and getting a GPS fix with a GPS test application. If the phone is only running A-GPS with no antenna, I would assume it won't be able to. With a true GPS antenna you should still be able to get a lock without the network(s). I might try with mine just because Im curious now (battery cover on versus off).
~T.J.
Ok, so here is what I found out. I put my phone in airplane mode so it would have no assistance from the mobile networks and walked outside. I opened GPS Test and I was still able to get a GPS signal quite easily. I let it narrow down to 15 feet after a few seconds then I closed the app, removed the battery cover, and re-opened the app. I still had zero satellites showing after 3 minutes. I suspect you would see similar results without the GPS antenna in the battery cover.
I suppose this means the Sensation XE only has A-GPS seeing as it has no GPS antenna built into its back cover?

That sounds completely legit, and I expected to be disappointed by getting your results. But something strange happened... and as soon as I get to 8 posts, I'll tell you.
Curious yet? I really hate having to do this, but I have to get to that 8 post minimum to link to pictures.
Okay, so here we go. First, I tested the GPS just onside by window at my desk, averaging an accuracy of 12-18 feet. (for the record, I'm running CyanogenMOD 7.1.0 alpha 9)
IMG_0750 by dirtyblueshirt, on Flickr
And was able to get a good signal:
IMG_0751 by dirtyblueshirt, on Flickr
So I went into the settings as you described and turned on Airplane Mode:
IMG_0752 by dirtyblueshirt, on Flickr
And to my surprise, I got a solid GPS lock:
IMG_0753 by dirtyblueshirt, on Flickr
So then I took off the cover... and as expected, lost the GPS signal:
IMG_0754 by dirtyblueshirt, on Flickr
To make sure it wasn't a fluke, I re-attached the cover, and was able to regain a GPS signal lock:
IMG_0755 by dirtyblueshirt, on Flickr
My only assumption is that the Sensation may also use one of the other antennas for GPS signal (what is that "Diversity Antenna"??)
So it appears the Diversity Antenna is an RX-only antenna meant to compensate for reception issues, but I can't find if it applies for the cellular radio only, or if it can supplement reception for the other antennas (GPS, WLAN, Bluetooth). My thought is that is can compensate for that missing GPS antenna which may be why the standalone GPS antenna was deleted in the Sensation XE. The HTC Sensation XE product page does in fact list the XE as having an "Internal GPS Antenna", which is identical wording to the Sensation's product page.
Interesting indeed...
~T.J.
EDIT: Is that GPS signal inside even? Thats better than I get even outside if so. I get like 6 or 8 usually with about that same amount of signal strength. Im not 10
00% happy with it, but it works...
EDIT: In the picture of the "lost" GPS signal, it says it still sees 10 satellites, did you not exit and come back into it? In fact, it says in use is 10 as well. Strange.

Yes, the signal is inside, but not by much, about two feet from the window. I didn't exit the app, but with the accuracy at zero and greyed out (with a yellow gps indicator) I assume no signal and the ten sats you see are just residual data. I'll do a second test later today.

If you dont mind me asking since you are the only one I know who has gotten that Beats cover... is the quality just as good as original ? Want to buy one for my Sensation too and since it works ok with T-Mobile I want to make sure i get my money's worth and/or if its possible can you load up a picture of your new Beats back cover so i can better see how it looks? rather than what ebay sellers are showing

So, I've been afflicted with the death grip issue at home something fierce. If I hold the phone in landscape mode as if I were to type with my thumbs, the wifi cuts out. It doesn't seem to matter how close I am to the wifi router or if I turn on Wi-Fi best performance. At home, the network is configured to use 802.11g for compatibility with some older devices.
At work, I run an 802.11n network (I'm the IT Director). While I've got much better access points and better line of sight, I have similar sorts of distances. With 802.11n the death grip issue seems less significant. The network never drops out completely (I lose maybe a bar) although network *traffic* seems to stall to a degree. This is true even if I go into other rooms where I don't have great line of sight.
I'm still doing some surreptitious testing (since I have work to do, too) but I thought I'd ask the rest of you if you're having seriously issues with the death grip, what mode is your wifi in? 802.11g or 802.11n?
I really haven't had this problem, when I hold it in landscape it goes down 1 bar but comes right back,I'm starting to think its device related ,just like the HD2 some of them had wi-fi issues and it was just the hardware couldn't do nothing about it but exchange the device
I used to have this issue until I changed the wifi performance to maximum and out a gel skin case on. Now mine doesn't even drop a bar from 2 rooms away.

I would notice the signal go down when I held it in landscape but it never dropped completely but last night I got the real effect of it. I was streaming a movie from my computer and viewing it on my sensation using splash top (only about 15-20 feet away from the roiter) Everytime I held the sensation and touched the "death grip" spot my video would stutter.. Tried setting the wifi to max performance and I have the tmo gel case on.
I guess one difference between this and the Iphone antenna-gate is that if HTC does consider it a problem and does fix it, they only have to replace the back cover and not the whole phone
I heard someone said foil on the outside helps out the issue, but it looks really ugly. Wonder if we can come up with a fix that can be done on the inside of the cover. Maybe attach more wiring to the connections or something..
Wonder if those cheap cell phone singal booster on the inside cover would help out at all.. hey if foil did then maybe one of the will shrugs
I just have to say I don't think this "death grip" is a hardware issue .... I think it is a software issue. I had a g2 and flashed cyanogen ... Worst WiFi reception ever. Went for a more stock based Rom and bingo! Also I noticed if you turn off mobile networks from the task bar and turn on WiFi, you will have superb WiFi...
On the sensation of course. Lol

Trying to Figure out the Wifi-Death Grip Issue
Something Odd happened to me, i wanted to share with the rest of the comments here because i have not been impressed with my Sensation's performance so far. I have had the normal low volume and the erratic sense speeds along with what Phil showed when trying to use the carousel, but nothing was more annoying as with the wifi issue. I got it five feet from my router and i have two routers and one is open and one has PS2K. I tried it with and without the cover and behold i lost my signal when i held it in landscape or put it lying flat. I decided i needed to go to a T-mobile and complain about it, but while i was waiting to be attended, i went ahead and started playing with the sensation they had on display. To my surprise i could not duplicate the issue at all, I checked their version and went to the advanced setting under wifi and it was no put on maximum performance. I pulled out mine and as you could imagine, i could not duplicate the issue anymore. I was puzzled because although i lost some bars, it remained connected and i did not lose the signal completely or as easily when i was at home. I decided not to look like a fool and when across the street to a Best-Buy, and logged onto their open network and had no issue again i tried to put the death grip on it, put it in landscape or lay it flat on it's back and although i was looking some bars, i could not duplicate what was going on at my house. I went back home and reset my routers and the issue is still there. So from what i can tell, i think we may need to find out if this issue is with some routers only or with the encryption used.
FYI: I have a N1, IPad2, HD2, MY3G and don't have any wifi or death grip issues with any one of them so i am seriously leaning to a software issue.
Whatever, the issue i can see Why Phil and a lot others do not see this issue and i can understand why a lot of us are experiencing the issue. Hope something is found out soon.
Routers i use:
DLink (DIR 601) Open network
Ambit WPA2-PSK
(i have tried changing channels and updating firmware on both routers)
Hi Guys,
Firstly a little history.
I had a Desire which I go branded on a post paid contract with Telstra in Australia and I loved it, was able to root and install roms......
Recently I lost it and I decided to buy one unbranded from ebay - I received this one and for some reason it had terrible network coverage in my house (one minute it has full bars and the next NO bars) and my previous one worked perfectly.
I ended up sending it back as I thought it was faulty and I got an upgrade to a Desire S at the same time - however this phone has the same issue and it only happens in my house (that I have noticed so far anyway)
Any ideas?? can this be fixed...
Thanks

I'll be honest I've noticed a slight fluctuating signal issue also on my desire s, I believe that some calls have gone to voicemail that I should have been able to receive.
I've been hoping that an improved radio will resolve this in the future.
Have you checked with your local telecoms provider to ensure that they're not having signal or mast problems near to where you live?

No i didnt bother calling them because i put my sim into my girlfriends wildfire and i get full reception almost 100% of the time.

Have to checked the 3G aerial connections? The 3G aerial is built into the battery cover on the Desire S. Take it off and you'll see a couple of brass contacts. Are these tarnished or oxidised? How about the contacts it makes with the phone? Is the battery cover seated properly? I have put my battery cover on a couple of times not noticing one of the little tabs on the cover is not in properly.
If the connection of these contacts is not properly made or they have oxidation on them, it would explain an intermittent signal. Does the signal go from zero to full when you squeeze the battery cover down?
The best way to clean contacts up is to wipe them with a cloth damped with lemon juice. It eats the top layer of oxide off and makes them shiny again. Obviously let it dry out before putting it back on the phone! Also check they have not been bent out of place slightly in attempts to get the blasted battery cover back on. I know I struggled the first few times.
I don't think it's a radio thing. They either work well or not at all. I've not ever had one go from full signal one second to nothing a moment later.
Yes i read about the tabs on the battery cover on another thread. They look ok to me.

I have the same problem, even without a case! Although, when I switch to GSM, I get full signal. But that means sacrificing HSDPA.
I am tired of low network signals in my home @ basement with Sensation ...
My wife with x10 mini gets enough signals on her mobile to send/receive calls without voice interruption and I can't even dial from it...
My friends tell me that my mobile mostly remains off but i know it's due to low reception...
How can such a small x10 mini perform better that Sensation?
Last option for me is to boost reception by Aluminum foils... Anyone tried such a Hardware Mod?

Alas, I can't say I've tried this but now that you've mentioned this option I'm tempted to experiment with it.
What i do have a lot of experience with is flashing and testing different (software) radios. You should read up on the topic of "radio" and "RIL" since you've assessed that location is not the problem.
Then again you might have reasons for not wanting to flash ...
If you really want to enhance your reception with hardware, this guy makes sense http://www.metacafe.com/watch/750707/how_to_make_a_cell_phone_antenna_under_5_minutes/.
best regards,
Lol... The initial part of video is exactly what i do when i get calls....... But that's really not the mod i would want... I want some extra foil inside casing that should not look bad from outside...
I once connected aluminum foil with the terminals with back cover off and its signals went from 3 bars to full 5 bars... But when i placed aluminum foil inside and packed back cover on it, signals dropped again...
I have tried ALL radios and RILs in the thread... With 10.56 i used to get 2-3 bars but with those i couldn't even send or receive a message... When it's 4 bars, it was working
With latest radio 10.58 and ics radio 11.59, It simply puts 'no network' when signals are low enough that are not ready to make calls...
So flashing radios is just playing with bar indicators. No gain ...
hardware antenna booster.

I understand.
It's weird that the mini performs so much better at the exact same location. Have you excluded the possibility that you have faulty hardware?
Amazon sells an antenna booster for HTC that basically enhances the antenna in the way you describe. Just search for "htc antenna booster". Even though they only cost a dollar or two, it might be more fun to copy their design and make them yourself.
I look forward to your findings.
Good luck!
Yeeeeeeesssss....
I made it... Today i tried myself to get a network boost and it worked!!
I called my friend today from basement and walked every corner of the Room to test the mod and he said my voice was crystal clear without interruption...
Then i asked him to call me and i placed my mobile in a place where i used to get absolutely no signals and he told me my number got through to him on first attempt....
it never worked in my room and now its working everywhere in the Room...
I am sooooo happy...
The only problem is, when i grip the phone then its the same situation as previously ... For that i have to ensure i hold my phone on thumb and index finger and keeping the palm away from the back...
But this much is also enough for now... In basement i won't hold it tight...
I seem to remember seeing this mod being done, but that it had a negative effect on battery life. Please report back after a couple of days use, I'd like to hear how you get on.

Maybe I'm wrong but did You try to change network mode setting in Mobile network section to GSM only.
It works for me in places with poor reception.
It will give you crappy internet, but you can switch it back to GSM/WCDMA Auto when you leave the house.
With GSM only you should get signal anywhere in the house or basement or any other place where any other phone can have any signal.

Haha looking forward to your vid to see where you placed the fool. I tried foil once, but didn't notice much difference. I read somewhere that aluminum isn't the best conductor, so I was going to try gold foil instead. Just never got around to it.
anyone ever figure out how he did it? lol
anyone?
signal fix
That's what I just did, from no signal at all-0 to 2-3 bars and I bet it can be done better and get more.
Can you tell me what is the result with and without your antenna in "asu" or "db". An example how much did it improve your metal foil. And anyway why did you choose one side longer than the other?

You bet it can you have made a half wave dipole the length of each element is critical depending on frequency used there are simple formulas to work out the exact length of the antenna
Still great work around if it actually works one problem is the case acting as a shield to your two tinfoil elements
Worked well for me.

Hi,
I am interested in this as well.
I can confirm B.
My wifi disappeared,so I lifted the two connectors and it was restored.
EDIT:
I just checked my phone.
I haven't got an A
That 'A' is still controversial... It comes in T-MoUS Sensations... Not present in European and XE Sensation...
Some say it's 4G, but then i read that guys with T-Mob using XE Sensation backcover getting 4G signals without any problems.. So it's not 4G ..:-/
Anyone? A million people having Sensation don't know what those antenna are for?
Ha, well that explains what the mysterious bump is on the inside of my back cover - it's another thing that would have been painted yellow if my phone had been shipped to a different part of the world!
A person makes a pretty good aerial, so try taking the back off and touching each contact on the phone in turn with your finger to see which radio's signal comes back.
"A" is clearly for a radio which has no purpose in the UK, or perhaps for one which can share its aerial with another radio... Could it be a different frequency thing, like an optimised antenna for a different GSM band or even for CDMA if the Sensation has a version that supports it? Or it could still be for 4G; just because you read something somewhere doesn't mean it's true.
I can personally confirm that the extra antenna is not 4G. I bought a white XE cover and have noticed zero reception problems in WiFi, 2G/3G/4G, and GPS.

just like tlloyd87 said, i m also lacking this antenna A in my back cover and i have GPS fully functional...
That D i agree is GSM network, but i can't say exactly if it's only one sided reception only coz i applied aluminum foil to only D and my network reception showed up and i dialed a number and got connected without any issues..
When i touched E alone, i had no reception at all..
I read that thread but it's not coinciding with facts... That PDF marks GPS wrong too...
One theory is that the photo from the filing actually shows the antennas switched (GPS for Diversity) meaning you still get GPS, but are missing the diversity antenna - IE - a Sensation 4G has diversity and GPS, a Sensation XE (and apparently some international phones) only have GPS.
I forgot about this when I posted, I have edited my above post. This has all been covered many times, you could search and read about it all.

The diversity antenna was described as being a "booster antenna" to try and improve reception and supposedly isn't used at all times. People who have put different back covers on without it seem to report no loss in signal strength, so maybe it's not used at all?
~T.J.
Just looked it up on Wikipedia, apparently a Diversity antenna is to mitigate interference caused by the radio signal bouncing off obstacles between the transmitter and receiver. Several aerials receiving the same signal means at least one of them should get something usable. I believe 802.11n wireless uses this principle.
Perhaps a diversity antenna isn't necessary for correct operation, but can improve reception where fitted?
Correct. MIMO (multi in, multi out) technology is the same concept/same thing. No one is just sure how often it's used, or if it's used at all currently.

HI guys..
I've a sensation 4g (tmous) with arhd 6.7 (but it does the same with stock rom..
As soon as i cover my phone with the case i notice losing a bar of signal, and if i grab the upper part of the phone I completely lost signal!!!
Can anyone of you try and see if is it normal?
Thank you and sorry for my bad english
It's normal as you're covering up the antenna.
On the Sensation the antenna is the whole back cover, and so holding it in a certain manner makes it lose signal. It is one the really annoying things with the poor loudspeaker that makes this phone not live up to the standards we are used to and often annoys me.
i swear my wifi connection is so erratic. sometimes i get awesome connections, sometimes it doesn't connect at all. sometimes my phone has full bars but won't connect.
while i do think it's the sensation to a certain extent... i also think you gotta consider the signal quality and strength of the actual wifi too. technology... sometimes ya love it... a lotta times you are confused and frustrated with it. haha.
Totally normal. Unfortunately.
