I have a question, does anybody know the placement of the antenna inside 6828?
I just purchase one recently and I bought hard aluminum case from pdair, I've always use aluminum hard case since 6365, dopod. however when I uses it, it seems that the antenna is blocked by the case, outside the case signal is all the way up, if I place it inside the case, it drops to 1 or even 0 and start searching for GSM signal.
I really like hard cases, is there any way around this? if I know the place of the antenna inside the PDA I might be able to do some minor modification on the case to get better reception.
it shld b bside the camera, where u can see the hp logo. does ur case comes wit magnetic? not limited to 6828, i experienced b4 on other phones tat the signal strength dropped due to the strong magnetic stick-on on the case.
The aluminum case doen't have any magnetic parts.
one of these days I might get arround to mod the case. hopefully I get better reception
Looking at the results of the xda-developers pool I decided to get an XPeria as it clearly out shined all other phones. I got X1i this Saturday and was shocked about the poor signal strength. I was so looking forward to using this phone and keeping it but was more inclined in sending it back. Now after a couple of days just browsing the developers site which I am used to as I had an artemis before this. I see this was not the last of the problems. There have been mentions of overheating and GPS lag as well as the WIFI being rubbish. I have found the following problems
1. Signals fluctuating and mostly no service when in hand even in some good reception areas. Normally on H when in the carry case but switches to G as soon as held in hand.
2. GPS is frustrating. My artemis used to lock within seconds while having an upto date ephermis file. But even with AGPS and recently downloaded ephermis file, I had to wait over a minute to move off. It locked and then it lost and then it locked again(This was when it was in my hand). Once locked it was stable. It was on Google maps by the way.
Right for these, I have found a temporary solution and we have to work on it to make it a standard solution for all X1. Apparently the signals definitely fluctuate when you touch the lower metallic part on the back which has SE logo on it . The opinion on the forums here is that it may block the signal. I think otherwise as I have covered that area without touching the panel with my hand and there has been no signal drop but as soon as you have the slightest bit of flesh on that area the signal drops at least two bars. This led me to believe that there is an electric conduction or possibly u earth the antennas as they seem to be touching that panel from inside as it has been pointed out before.
So simple test was to put a cling film on that part and then test so I did and walah!! There was no signal drop and it worked flawlessly. I think it’s the same problem with GPS as well.
Now I couldn’t carry on using my phone half mummified. I had to take the cling film off. This is possibly the solution to everyone’s problem but I need someone to suggest either a plastic cover for that area or some sort of coating which does not conduct electricity. I think that will definitely sort the problem.
I think you've got a faulty X1 there mate..
Can you take it back to a store and compare it against another one?
The signal is weak on this compared to some other devices, (it's not as bad as the vario though), however I've never noticed a drop in signal by holding it, so I suspect somethings awry with the one you've got..
GPS signal is very very good with the later radios, what version have you got?
I get a lock within 2 seconds (8 seconds from hard reset or flashed a new rom), and it's very very accurate when it does lock.
My GPS works very well (better than htc cruise) also with previous radio.
So I think you have a fault X1, like say by fards.
I'm with Fards on this, I don't get issues when holding the phone and GPS is snappy.

Thanks guys. I know it has been discussed a million times before but I have compared the phone with other XPerias and it is the same. There are atleast 4 threads pointing out the same. My X1 would have better signals than my artemis as long as i dont touch the back base. Have you all got silver X1is? If so then can you check if you touch the back panel which i mentioned, if there is any fluctuation in the signals(its not instant it takes about 10 seconds for the phone to show the loss of signals).
I have updated radio to 55 and tried the two new stock roms which are R2A for O2 and 010 generic. The phone still looses signals but not completely when i touch the back panel.
About GPS, it does get a lock very quickly but looses it for a short while when i touch the back.
Anyway if someone else comes accross the same problem then please write here as I am sure there is a solution to be found. I was looking at the following
Clear coating
Antistatic spray coating
I must have missed those threads then.
I have a black x1, and definitely don't get any of those issues.
gps is steady and strong.. monitoring it now... as I type. 6 birds locked standing next to window in house hdop 0.6m which I think is very very good
gsm signal on 2 bars and steady
I had the same issue just once. And even when X1 was in the Brodit car holder.
In my case the soft reset was sufficient to solve the problem. But I guess that you already did that.
fards and pelriog? did you experience any fluctuation when touching the panel?

Same here, touch back panel, hold for 10 secs and signal drops 1 bar. Currently on 3G network, going from 2 bars to 1.
(And yes, my W810i gets a way better signal in low coverage areas. However, usually not a problem, since I hardly encounter Vodafone low coverage areas in The Netherlands).
Tested 5 times. Dutch Vodafone X1i, R2 stock ROM & stock radio.
Ok I did the touch the panel thing and my bars increased by one... hmmm perhaps there is another faulty batch out there as I get great signal (touch wood) and my gps is very responsive and accurate...
Silver X1 here.. Been touching it up for about 15 mins now
It does seem to drop by 1 bar when touched, but also drops if i just put my hand really close to the back without actually touching. hmm..
what concerns me more is how it just drops the whole line randomly and gives an x then has to search again. Lost a good few calls from that..
well here ive got no problem at all with signal.
But GPS does suck even though most people everywhere say X1 GPS is awesome.maybe it is just my zone/country.. could that be possible?
uhm.. of course not, their satellytes afetr all.
I have disassembled my X1 myself and found that under lower part of backside (piece that have SE logo) is an antenna of some kind.
The antenna is a thick circuit that ran on top of another piece of plastic that cover the loud speaker.
The circuit only have 2 contacts to the main PCB.
My guess is that the reception site of either GSM or GPS is on that part.(may be bluetooth or WiFi too, but I think that's not it)
I wonder what SE/HTC engineer is thinking, putting antenna on this part of the phone! (covered with my hand everytime I use it!)
The solution is "use bluetooth headset" and "hold your phone upside down" and you will be fine.
Yeah, mine loses a bar when touching the metal case at the back, I've not lost any calls (that I know of) because of this though.
I had a look under the speaker section myself last week, and can confirm the antenna circuit over the speaker section. Underneath there's also what looks like a tiny external antenna socket... we could mod our experias to have a rubber duck aerial? Who's up for walkie talkie lookalike xperia?
lol @ walkie talki and upside down. I think the designers have done a very poor job as far as the antenna location is concerned.
Tumpin does your phone loose all signals when in your hand?
Taking this seriously as suggested in my first post has anyone tried putting a cling film on or to that matter anything to cover that area and holding the phone. I did it with the cling film and there was no drop in the signal. So i think it is just a matter of us using some kind of invisible coating or cover on that area so there is no static conductivity. Look at post #5
I would appreciate if everyone gives there suggestions as well how to deal with it. For the people who took the phone apart you could have put something on the inner side to block the static discharge.
I returned my xperia for the second time for signal problems. The problems started after it was repaired for the crack in my case. After that the signal was very poor. GPS was not working in 90%. I wait for 15 minutes for signal, but the only thing that happend was heating the battery. Also HSDPA have a weak signal. In most times I only can use GPRS. The first time I returned the phone for this problem nothing changed. And this time I had a new crack in my case, so I hope they send me a new one!
Im using a X1a and I find its GSM/3G reception is really poor, I already upgraded the radio to the latest but its still the same poor poor reception. Specially when Im using the metal case I frequently get drop calls on my device

Just curious! Any chance that you see what for are the two metal plates contacts from the metal cover of the phone? Those near the SE logo. These two and the other two towards the camera are there for... what? The metal cover is used for something as when you rig in the phone and all four contacts are "online" but what for? Thanks!
I have a black X1i and noticed that reception increased when using it with the keyboard opened in horizontal position.
Same here, I tought it was because I open my metal case that is why reception goes up.

I bought my G1 used off of eBay about 9 months ago. From the beginning the GPS never seemed to work that good. I didn't use it very much until recently when I got a 2600mAh battery for it and upgraded to CM6.0.0. I decided to investigate the GPS problem further as I wanted to be able to use the navigation feature on it in my car & work van. I was trying to find out where inside the phone the GPS antenna was so I knew which position it would get the best reception in the car. That's when I found this pic:
(sorry, won't let me post links due to being a new account! This was a pic of the antenna tape on the outside of the case next to the camera lens)
And when I looked closely at that area of my phone this is what I saw:
(sorry, won't let me post links due to being a new account! This pic was 2 little tabs sticking out from the original antenna tape, looks like it had been cut off!)
The antenna tape was missing! I can't believe I have been without proper GPS operation all this time. It seems the only location service I was getting was triangulation from the cell phone towers. It makes me wonder if the person I bought the phone from may have intentionally removed the antenna so he couldn't be tracked?
Anyway, I made my own temporary antenna out of aluminum foil:
(sorry, won't let me post links due to being a new account! Just imagine a piece of aluminum foil cut to fit where the original antenna tape goes and taped to the case over top of the original antenna tabs)
Went outside to test it and picked up 8 satellites right away using GPS Test app. Oh I was so happy and mad at the same time! I used the navigation most of the day yesterday. A few times it lost signal, probably due to poor contact between the aluminum foil and the tabs from the original antenna.
So now my question..........Where can I get a new proper antenna from? Does it come attached to the case if I buy a new case or is it a seperate part? So far in searching for G1 repair parts I have not been able to find the antenna as a seperate part & cannot tell if a new case comes with the antenna tape attached.
Thanks for any help!

I can't answer the question about where to get parts, aside from looking around for broken parts phones (i.e. cracked screen)... Gotta say -- that's a funny story... and a good thing to keep in mind for others having GPS issues.
It is also why I don't buy stuff like that used.
Hi everybody,
I have two Nexus 4, both running CyanogenMod 11 M6, same baseband version (M9615A-CEFWMAZM-2.0.1700.98)
I experience signal lost or weak signal on one of them.
Both have a simcard from the same provider (china unicom) and are right now on the same desk. And as you can see on the attached screenshots, their signal strength are different :
My father went to a repair shop last year to change the screen that was broken. And reported me signal lost (or weak signal) since then. He never made the connection between these two events, but I'm supposing that there is one. Even more when after a few months, he finally brings me his phone and I looked at the glass they changed : I could see the square stripes on the surface if I look the screen from the side whereas on my original Nexus 4, it was not that obvious. I deduced (maybe wrongly) that the screen quality was not as good as the original (no gorilla glass or whatever) and that maybe this affects the antenna reception, or that they maybe didn't reconnected well the antenna when replacing the screen.
Anyway, I never dismounted any phone so all of this is pure suppositions, and I'd like to have your opinion on this problem :
Where this signal lost could come from ?
Do you recommend me to change the screen ?
If I go to another repair shop, what should I ask them to do ? check the antenna connection ?
Thank you a lot for your advices :good:
since i first started using my lg g2 (new) it had problem locking my location (unless if im connected to wifi) as i researched it seems like a common hardware problem and i plan to try to improve the connection between the pins and the back cover but im not sure about something i noticed when i opend the backcover that the silver area on the backcover got stuck in some glue and a piece got a bit seperated from the rest is it connected to the gps is it the gps aerial? do anyone no whats the purpose of it or is it just another sticker..
