Drop my Note 2 this morning and since then, the (GSM/LTE) signal seems unstable. Most of the time there's just no signal at all, a big O in status bar. Sometimes I manage to get signal by pulling out battery and knocking around the phone (!!), then after a while it gets back to no signal. What could be the problem? Did the drop this morning damage the GSM antenna? If that the case, where is the GSM antenna in this phone? I might want to open it up and check tonight when I get home.
PS: Check with other guys in the same building with AT&T, they seems to be fine regarding signal, so probably it is just my phone's problem.
Re-seat your sim card. Squeeze the antenna module.
Maybe open it up and check the internal connector.

That's the plan. Just not sure where is the antenna module though

Hi,
I have had my HOX for 3 weeks now and since yesterday (so, not a new thing), I keep losing the signal in my appartment, in some places outside. Oddly enough, signal is OK (tho just 3-4 bars) in my office.
1. Could this be related to the WIFI antenna issue even tho it's not WIFI issue? In other words, is there a chance that by fixing the WIFI antenna issue, I can get solve this?
2. If not, what are my other options? The garanty is already voided so I cannot send it to HTC for repair (voided by an "unofficial repair center" after the screen got smashed by dropping it from like 1m... - it's very possible that the fall or their repair broke something else, but the repair was already 2 weeks ago)
Thanks for your help!
First thing I'd ask is are you rooted? Have you been playing with radios recently?
If not, the next thing I'd look at is trying to find someone else with a micro-sim, and asking to borrow it. If they still get a good signal on their network on your phone, it might be your sim card. I had a faulty one once which just started dropping network like you describe. It can happen.
If their sim card also shows poor reception, you might have an aerial issue caused by the unofficial repair centre opening the phone up. (Although from the feedback on the WiFi issue thread HTC have worrying repair standards too).
If you can't find another micro-sim, just try finding someone on the same network. This phone (when working) has excellent network reception (better than my previous Desire S) so if a side-by-side comparison shows a big difference in signal strength, again I'd think about getting the sim replaced.

If your replacement sim still has the same problem, then I'd consider opening the phone up as per the video guide in the WiFi Issue thread in the general section. Seems to be quite easy if you are careful. It is unlikely that the same aerial for the WiFi is also the 3G one, but I've looked at the tear down pictures, and can't read chinese! If i find out which one it is, I'll update this post. If not, just check all the connections.
Hi,
I have also been having this network drop issue but only near my office. The reason I think is that my office is between two towers and every now and then it tries to balance the traffic on the networks and hence keeps disconnecting devices from one to connect to the other one... However, I have cut out my normal sim into a micro sim and that was done by the guys at the shop from where I bought the device and they had said that if there are any issues, then please order a proper micro sim and use it....
I think that might also be the problem.....

All,
After checking that my SIM card wasn't in cause (used a friend's HTC One X to test my SIM card and test with his), I broke open the case and saw the problem.
The problem is the damn design of those antenna contact! I saw probably around 10 of those small metal piece that are supposed to be a bit "up" and somehow touch the contact area on the back cover.
I found that 2 of them (in two different pairs, they all seem to be in pair to create a closed circuit I suppose) were a little bit lower than their counterpart, so with a flat screwdriver, put them upright, closed the case and voila, I am enjoying network with full bars since yesterday.
If the issue comes back (and it probabl will, if they got bent the first time it probably means that the metal already was bent beyond its elastic deformation area), I'll probably end up buying a soldering iron a add some patch of silver to increase the height of the contact zones. That's .... just lame I am sure they had a good reason to do that, but seriously!?

Glad you got to the bottom of it. Yeah I think the design choice is forced from having the main body of the phone slide in at an angle into the outer case. If the two parts just clamped together like a more traditional phone build, then they perhaps could have used a different approach.
I'm putting off opening mine up (I have the dreaded WiFi drop issue) as my current case puts just enough pressure on the screen to act like a permanent squeeze, halting my problem.
Would be interested to know if the problem reoccurs like you said it might. Keep us posted.
Hi everyone, I got my phone about 3 weeks ago and worked well (rooted it, then flashed it with a rooted Brazillian rom) till 2 days back, I forgot to register the IMEI with my service provider (using a company phone number) and got my incoming and outgoing calls blocked, but I was still able to use data connection. I didnt give it much importance since I work out country and the nearest office is 3 hours away.
I was able to call using another SIM card (personal phone number) and register the IMEI with my other provider. Couple of hours after that, my signal went dead, I then tried several SIM cards and still no luck. Messing around afterwork, I connected the external antenna to the phone, and I got signal back! I left it on all night on my desk. Next morning came back, disconnected and lost signal again.
My companies SIM card is working well on other phones. The only problem I have is that I need the external antenna connected to get signal.
Has this happen to onyone else? Ive searched several forums with no luck.
--------------------------------
I did some testing and went to the cell tower thats in our camp and got a good signal.
Seems that my internel antenna is messed up or something is not right with the radio.
I dont want to open it until I go back to the city. Anyone knows how to check with an app or something?

Found out what caused my problem and gave it a very simple solution. (http://forum.xda-developers.com/showthread.php?t=1273292)
The problem was that I plugged an external antenna that was a bit more thicker and ruined the internal contact that the internal antenna uses.
The solution was cutting a thin copper wire to 16.6cm long, plugging one end to the middle of the external antenna socket and folding the wire around the battery so it would touch it. Signal didnt go back to 100% but worked at about 90%.

Same problem here! I use a wire connect to external antenna too.
There is any solution for a internal antenna back to work again??
Its seems as a very bad design error
Hi,
I am not sure but after my phone fell from 50cm table! my phone always shows "no service".
I changed my SIM card and flight on/off mode. It didn't work.
The other phones sees the signals but mine doesn't.
Yesterday I recognized that if I am very very near to the link of the service provider (say 100m) I have signal! and can connect.
I think my antenna has vey poor performance. Do you have any idea to fix it?
Thanks in advance.

Same problem! It randomly lost service signal, and now I am missing signal everywhere except in a big city, but even there I mostly don't have signal. I have tested this with 3 other friends who have the same service provider and have 3 out of 4 bars - while I have 0.
I lose signal when the phone is in my pocket, when holding it below a table/desk (in school), when holding it wrong in my hands. It's a really annoying problem and I'll send my phone back today.
Try squeezing the phone a bit, maybe it slided around inside the case a bit and lost the connection to the antenna
Sounds strange but fixed my Wi-Fi temporally (at the end I bend up the antennas a bit...)

That only works with Wifi, but the wifi issue is already fixed on my phone.
Hi, i recently got this one x (13 months old, out of warranty)
and found that the signal reception of this phone is quite weak!
I tried with SIM Cards of different mobile carriers but same issue with all of them..
it doesn't captures any signal at most of the places however in the areas with high signal strength, 3-4 signal bars appear and phone works fine!
Is there any fix to it? (Hardware issue or software?)
Also, the G-Sensor appears to be faulty, sometimes rotation works and sometimes it doesn't!
and the proximity sensor doesn't work at all!

What ROM are you using? If stock ROM, try doing a factory reset. If not, try reflashing the ROM or try another ROM.
Hardware fault it is, connectors are in very bad shape, nothing can be done
how do I do that

Hi,
I desperately need your help/advice.
I'm suffering from the same problem as you are, running my HTC One X on Stock NON-Rooted.
I've tried to factory reset several times, but still, I'm barely getting 1-2 bars of Signal Reception at Max, while in most places I get NO SIGNAL!
What did you do to fix your phone? Which jumper were you talking about?
I'll appreciate your advice...
Zach.

Hardware fault it was.
I was on stock rom, restored stock backup multiple times, did factory reset, none worked,
ultimately just one jumper, did it all! :laugh:

There are some pins on the motherboard that makes contact with the antenna inside the back cover. With time, those pins bent downward to motherboard and makes poor contact with the antenna. You need to remove the back cover and repair those pin or bent them back up.
look at this thread, its for the wifi issue, but essentially the same solution. http://forum.xda-developers.com/showthread.php?t=1688538

Thanks, I've already tried the pins solution. I even replaced the whole back cover.
I guess my only chance is to replace the inside coax antenna cable, unless the problem lies inside the motherboard somewhere...
Thanks anyway...
I keep loosing signal with any sim cards i use. Any fix?

not a common problem, though someone did mention something about problem on 2G or cdma on LOS14 recently, maybe try update modem or flash a different one.
(if you have I9195 here are modems that already been extracted from stock roms https://forum.xda-developers.com/ga...dem-samsung-galaxy-s4-mini-gt-i9195-t3390780)
If still weak signal then it could be poor grounding of pcb or antenna connection, remove battery, remove internal cover, check connections/reseat leads also tighten screws of motherboard/remove check for tarnished/corroded contacts. (if you put a small piece of wire on the test point (micro rf connector) with battery in you might suddenly see signal strength spike meaning it's your antenna/connection is the problem)

it might not be that, did you test antenna with little cable on test point (just take battery cover off). I was just giving an idea of possible problem. Some people have found just tightening the screws that hold the motherboard fixes it. It could be something else entirely like eg software, is it the same on all modem/baseband & other rom?
