[Q] bad reception - HTC One X

Hi all,
i replaced the screen of my HOX when it got cracked.
i replaced it myself with a new screen from ebay.
the screen works well but after the replacment i have a really bad cell reception.
mostly i only have a gsm signal, a 3G signal is rare.
inside a house or building i have no signal at all.
i opened my HOX again to check the coax cable but this was not the problem.
can anyone tell me what hardware parts take care of the signal from my provider?
thanks.

nobody?

is it possibly that the two connectors circled in red are responsible for the provider 3g signal?

Desire POOR RECEPTION

I have had my new Desire for 2 days now. It is the telstra version (australia) (which also has the non working GPS).
I am using my postpaid telstra sim in it which was previously in my blackberry 9700 which is NEXTG capable.
I have found the reception to be noticeably poorer. My BB would show full 5 bars and would never drop a call or have any issues with calls breaking up and being unable to hear the other person. The actual 'bars' was about 2 out of 4 for the android. it is 5/5 for the BB. The android signal strength meter shows anywhere from -90 dBm to -105 dBm in the same spot. My BB9700 shows -70 dBm !!! in the same spot with the same sim!!! -70 is as good as it gets.
for example today, i had trouble maintaining a conversation for more than a few minutes without it breaking up and having to repeat myself a few times. This happened at least on 2 separate phone calls with the desire. Granted, it never cut the connection completely.
i got sick of it because i was on call and had to be able to be contactable 100% so I swapped the sim in to the BB and continued on my conversation – 30 minute conversation without a hint of an issue.
I have always found the BB to be the ultimate in the phone department – but i was seduced by the pretty screen and graphics of the Desire and also the integration with google apps – which i use a lot of.
I also note that people have been complainng about the nexus one over in the US of A regarding the reception quality too. I bet it is the same thing.
The call quality is quite good though. The speakerphone is crap though.
The other bits of the phone are great – screen, speed, apps, and everything else everyone said was good... though i havent heard anyone complaining about the reception
Just want to know if anyone else is having similar experiences and if it is just me. Can ppl with phones that can show signal strength objectively (i.e. dBm measurements) look into a comparison? and also state what network you are on?
Im now thinking it is too unreliable to use as my primary phone... which is too bad. I hope it is a matter of a software update or somesuch to fix this. The price one pays to be an early adopter.
I suspect this applies to your Desire?
bloody hell... same thing happened when i tried what that dude did... pick up the damn thing and the signal goes to hell
devastating.... this is sad.
It's because the antenna is at the bottom, and you're most likely covering it with your hand when you pick it up.
It's quite worrying this sort of hardware design flaw wasn't spotted by HTC. I too can confirm it happens on mind has well....at least I know how to hold it now!
This thing really is a nexus one+sense huh? It even copies the 3g coverage issue.
I just tried that and found the same problem...that is really a big problem.
hi, even if that shown in the video partially occurs to me as well I can't say I'm noticing any difference with my old handset (touch hd)
I have currently got an O2 simcard in my desire with GPRS reception only.
I do not have that issue, will try with my orange 3g sim as well.
Has anyone a work around or advice for this?
Held tight in the palm I lose bars, held to the head I don't - enough of a different grip when actually using for a call. Cupped in the fingers rather than the palm, no loss.
I have the sim free desire bought from UK, and I'm using the optus prepaid sim. There is no problem for me at all.
Maybe update the radio would fix the issue, but it seems no radio update atm.

HTC Desire Bad reception Solved!!
Hi All,
I recently bought a second hand HTC Desire and had the same thing: Bad Reception.
I tried EVERYTHING, Rom's, Radio's, Task-killers, etc. but I found the reason was something completely different!
Now my Desire has FULL 4 bars reception: What did I do?
Remove the battery cover, take out the battery, unscrew the two small Torx screws at the bottom left and right.
These two screws hold the antenna cover which is actually the antenna itself!!
You will find two spring-loaded contacts at the left of the phone on the circuitboard: these are the antenna contacts. Pry them up al little bit and clean them with some alcohol.
Now clean the two grey contact surfaces in the antenne. Do not use any scratching tool, but use a small pencil eraser!! The surface will stay a bit grey, but this is normal.
Now you are done!
Put the antenna back in place (bottom first) and put the 2 screws back.
Boot your phone and you will have good (4 bar) reception like before.
If you want to check?
Before you do anything "dial" *#*#4636#*#* , choose "Phone Information" and look at the signal strength.
The lower the number of dBm the better the signal.
Same as: the higher the ASU the better the signal.
Do the same after cleaning and you will see the result.
Succes to you all!
Extra: The antenna is at the bottom of the phone, poor design choice, we all know.
However:before -when holding the phone- the Signal Strength went from -103 dBm tot -119 dBm and then to 0, meaning losing the connection completely.
Now, the reception at the same location when holding the phone goes from -79 dBm to -85 dBm still holding 4 bars and having good reception.
My guess is that with all the Desire's these contacts corrode over time, so cleaning does help to get the phone back in it's original condition..

I did the same thing when I was struggling with poor GPS - opened the phone and bent all contacts a little bit. Confirm that my (or my wife's more accurately) Desire now has outstanding GPS, 2G and 3G signal. This screenshot shows the two contacts mentioned by Satbeginner.
It is worth mentioning though - if your phone is still under warranty and has never been opened this procedure will void your warranty - you have to break a seal on one of the two screws to remove the antenna.

tips for getting 4g reception indoors?

i have a pretty poor signal (3g and 4g) inside my apartment. 4g doesn't come in at all really, and 3g is about 3 bars at most, sometimes it briefly goes to 4 bars. i live on the ground floor of an old brick building, but i'm willing to try any tricks to get a 4g signal indoors (making a ledge for the phone up by the ceiling? by a window?). if i stand in front of my window on the sidewalk i get a fine 4g signal, but i don't want to set my phone on the sidewalk outside to wireless tether
has anyone experimented with any techniques to get a good signal? i heard 4g has a more difficult time penetrating through walls and insulated glass (i just have old windows with 1 single thin pane of glass). is there any way to position the phone to best get a signal (avoiding contact with certain parts of the phone? where is the 4g antenna specifically within the phone, at the top?)? can i somehow make an antenna somehow and place it outside my window and connect it to my phone in some way? are there sprint indoor antenna booster devices of some kind?
forgive me in advance if this has been covered... yes i did try searching but unfortunately when the device itself has "4g" in the name im getting a lot of invalid results
thanks!

[Hardware fault] 3G/GSM signal loss

Hi y'all,
I have been battling to fix my HOX 3G signal for months, I have taken it open, bent all the pins I could find upwards but it was still [email protected]
Where my iphone, defy had 3G or HSDPA signal, I only had Edge, where they had Edge, the HOX only had G.
I even changed the back cover but it was still the same
So one day I managed to break the antennae cable (after reopening and closing so much) and I realized the antennae connects the little L board which then connects to the antennae on the back cover. (not sure if it was posted before but where ever I search no one mentioned any 3G or GSM antennae location or diagram)
Long story short, after replacing the L board, my phone is finally seeing HSDPA signal along with every other well built devices I have/had.
Those with antenna problems can check the following:
Try flashing different radios
Check that the contact on the L board is connected with the back cover (the back cover plates which makes contacts to the L-board should be slightly dent)
Check that the antennae cable is secure on both points (L board and motherboard)
A loose connection on the antennae could cause signal drops or no signals at all.
Hope this helps the others, now I can finally enjoy the HOX as a phone...
ps I brought the L board in China @ $7.5, also replaced the antennae cable @ $2, not sure how much it will be in your area. I attached the pics of the L-board for those who dont know what I'm on about.
Cheers!

[Q] Signal strength is poor or none

Hi guys. I've got a problem with signal on my phone after I've opened it to change charger port(wasnt working so I bought one on ebay).
As I remember I didnt touch much but it seems that I did, because I've tried to flash new radios and then entire factory image.
Do you have any Ideas what I did wrong and how to check what kind of problem is that? I mean the signal is always there but at -113 dmb for hspa and -85 for gsm. I can access network only when near base station.
IDK but you can try flash a new baseband, as basebands control the signal strength in a phone
the cable for the radio is unplugged or damaged.

you mean that long black cable on the right side(on a picture). It could be damaged, yeah, because sometimes few bars appear and then again nothing. But I don't understand why it shows signal strength -75dmb (and as I read on wiki it is normal value), but bars are not appearing

wifi antenna

I recently replaced my note 2 chassis but found that my wifi signal has decreased (around 2 bars)
does anyone know where the wifi antenna is located as i can just salvage it from my old chassis.
I exchanged the below component but the signal doesnt seem to have changed at all
Hi!
How have you solved this issue?
I bought one replacement cover too and I'm having the same problem.
Thanks
