[Q] Signal drop (phone network, not wifi)

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.

Signal loss inside buildings, antenna issues?

So I have the Google Play edition Samsung Galaxy Nexus 16GB. What happened was my power button gave up so I ordered a replacement on eBay and carefully opened up the phone to replace the power button.
After reassembly, I immediately started having signal issues. Basically the phone loses all cell signal inside any building. Once I step outside, signal comes back.
Has anyone else experienced a similar issue?
One thing I have to mention is that upon reassembly of the phone, there was a thin black wire with a tiny coaxial like connector that I disconnected but couldn't for the life of me get it connected again. Could that wore be the problem?
Any tips on how to get it connected again? Is it supposed to snap in? Will I hear a click once its in place?
All help and suggestions appreciated, thanks

That is the line to the antenna. You are basically running without an antenna now. Connect it!

Basically, signal strength of GN is very weak.

Connect the antenna and yes you will feel a definite snap when it is seated properly.

Nexus 5X service manual?

Is a service manual for the Nexus 5x available?
Long story short, I was having a problem with my camera, so I whacked the phone on the palm of my hand a couple times (yeah, that might help! [lol]) and after that I lost the network (no bars at all, just a blank triangle always) and nothing I have tried has been able to bring it back.
I am on t-Mobile running 7.1.1.
I cleared the cache, tried different combo's of network settings (2G, 3G, 4G LTE), rebooted in safe mode, replaced the SIM card and tried everything else that I could find in various threads. Nothing works.
I've opened the back of the phone previously to replace the glass (as a glass+frame module) and everything worked after reassembly. So I am willing to reopen the case and poke around but I don't know what to poke at.
So maybe a manual will help or else if anyone has any help they can offer, that would be super!

No one able to offer any help or ideas?

Well I'm thinking maybe the antenna connectors are not so much connected after you tapped the phone. I found this thread which talks about the location of antenna connectors on the back of the phone.
https://forum.xda-developers.com/nexus-5x/help/lte-antennas-located-t3234795
ifixit has good information on it.
Sent from my Nexus 5X using XDA-Developers Legacy app

When I looked at the antenna connections with a magnifying glass, I could see that (using the same orientation as the photo you point to) one of the two prongs at the top right was bent and the single one below the top right two was also a little bent.
I stripped the phone down to the mainboard and straighten out both bent prongs. They looked pretty good to me under the magnifying glass. I also spent some time looking around these areas and at the other antenna prongs. Everything seemed to be in good order, as far as I could tell.
Unfortunately for me, the phone still doesn't get network or GPS connections.
I either need to find someone capable of testing these connections or a new mainboard or maybe phone back.
Thanks.
P.S. Here are some photos of the damaged antenna prongs before I fixed them as best a s possible.

Any more ideas friends?

Wifi Bluetooth Antenna problem with connection

Hey guys,
I have a problem with my OP3. I dropped it and it had a big dent on the back. So I decided to open it an try to press the dent back into shape.
After reassembling my Wifi and bluetooth are broken. I can get connections but the range is realy bad, about 5m for Wifi till it disconnects and about 5cm for Bluetooth.
I opened it a second time to take a look if i missed a connector or something and i saw a clip (those small things that connect to the back of the phone) was broken so i ordered a sparepart (it was the headphonejack circuit board) and changed it but its still not working.
Does anyone know where the bluetooth and wifi antenna are positioned ?
Have i just broke my phone or can i change something to get it back to work ? Everything else is working fine.
Thanks in advanced
Dennis

Same problem here! After I replaced the screen I lost my WiFi and bluetooth connections as well. WiFi is working in a range within 2m.
Is changing the coax antenna cable a solution?
Many thanks in advance from me as wel
Ken

Glad I'm not the only one, so maybe we get more help when more people have the same problem.
I changed the backplate cause of the dent and because the antenna is built in there but didn't change anything.
I have ordered a coax cable and will replace it when it arrives, could be today. Will post afterwards if this helped, but I'm not realy confident in that because i haven't done anything with this cable while repairing.
Maybe someone knows more about this, i just don't get why it is working but has no range, makes no sense to me ...

I have opened my phone several times now, but nothing seems to work.
Do you have an update on the coax cable yet? I hope it works, or the one plus 5 has to hurry ?

Hey there, same for me, opened it up to 10 times now but nothing helped, coax cable was a failure too. I realy don't know what it could be.
I'm about to wait for the OP5 or get a used 3(T) depending on what the . Was thinking about getting one with cracked screen and change everything but not sure if i should try it.

I have the same problem now. Any updates?
Hi guys! Yesterday I changed the camera of my OnePlus 3 because it wasn't focusing anymore, after reassembling my phone I noticed it wasn't connecting to the wifi anymore, tried Bluetooth and it was the same problem... I had to be really close for it to connect
Did any of you had any luck solving this problem? Did changing the board in the bottom of the phone not solve it? It seems that's where the WiFi is... Or maybe changing the backplate
Thanks in advance!

i also have same problem , need fix

Anyone found a solution? I had the same problem when I replaced the fingerprint sensor + the battery
I've been without wifi for 4 months now... Any help is appreciated

Hi, guys. I have the same problem. Did anyone find a solution?
I replaced my rear camera and the loudspeaker, at reboot wifi was not working. I noticed that if I'm near the access point network is detected but with very poor signal strength. Thanks.

Hi, maybe I could have found a possible reason to our lack of wifi and bluetooth signal.
Please look at this thread and give me your opinion. Probably your mainboard shows the same problem.

GPS not working

I bought a supposedly new HTC 10 off ebay a few months ago, and just realized on a recent trip that location service is using only wi-fi & cell. Once I am out of signal range, I get no location data, and GPS not working.
The phone came S-OFF and running WWE software, which I have changed to US unlocked using RUU, currently running 2.51.617.32, baseband [email protected]_76.02_F.
From a previous contact with HTC, they told me the serial number is that of a Sprint phone. I am assuming that this is a refurb of some kind.
I have installed GPS Status and tools, and the app can see the satellites, but cannot get a fix. Hardware check says that the sensor is OK. I have cleared AGPS and that made no difference.
Changing data from 3G to LTE to Auto, or on & off (per a couple threads at xda) made no difference.
I am unsure what to do next. Phone works well otherwise. Would flashing a Sprint radio help? perhaps a different kernel?
Any advice appreciated. TIA.

I had this issue after a battery replacement. Essentially this thread worked for me. Once the HTC 10 was opened up and the rear casing removed, there's a v. small copper prong located next to the headphone socket and it needed a bit of careful prying so that it could make contact with the back plate of the phone once rehoused.
So it could be that your new phone off ebay is a refurb and has been previously opened?

I would try a Sprint ROM before opening it.

finally found someone with some 10 repair experience haha. I just noticed my GPS won't lock, assuming it's due to screen/battery repair. I have over 5yrs phone repair experience, so salty i am in this spot.... But I have been many times with HTC repairs, and eventually figure out hte querk. Any other insights? I opened it up yesterday and couldn't get a lock still even without back frame shell on. I then noticed the top pin above the headphone jack was depressed most likely due to prying when opening, i carefully bent up and it didn't break, now making connection with back cover frame but still no gps lock.... also try reconnection of the top daughter board flex where hard gps chip lives....
Update: Twas the pin at top, and flashing RUU that got me up and running GPS again! woohoo!

Thanks by the help!
The last week I change the battery and I lost the GPS signal. After reopen the phone, the GPS pin it was in bad position. After move the pin, the GPS it is working again!
