Bad reception ...and solved - Captivate General

My Captivate had really bad/ no reception. I tried different roms but with no result....
So finally thought it had to be mechanical. Looked the Captivate up on ifixit and opened it. And indeed, it turned out to be the connection of the antenna to the PCB got loose....plugging it back on the PCB and....full reception.
I didn't see anybody here with the same problem, so just posted to let you know for another solution for bad reception.

HTC One S WiFi Signal reception hardware issue - Resolved

I am not sure how many of you faced poor wifi reception on your HTC One S.
I had very poor reception right from day one. Tried various Stock ROMs, CM10, AOKP, CM10.1 etc.
Searching on google didnt help and all I could get was issues related radio (luckily I never had issues with Cellphone signals) and
some issues were related to Wifi on JB.
I came to the conclusion that my issue was only specific to my hardware.
Wifi signal reception was just one point around 80db or so.
There was no warranty on my phone since it was used T-Mobile purchased in India.
When I almost lost the hope, one fine day googling landed me on a similar issue with our big brother htc one x.
Here is the thread - http://forum.xda-developers.com/showthread.php?t=1688538
When I did the squeeze test on my one s, I could notice improvement in reception. I was so glad to nail down the problem area.
I didnt want to solder my HOS, instead took three threads of copper (from Electric wire) and threaded them together (like "U" as shown in picture)
Placed them at the point of contact (shown as "1" in the picture) so as to make good contact with the back cover (shown as "2")
Just put the cover back, and my wifi reception is awesome now!!!!!!!!!!!!!!!
Posting my experience for the benefit of others, if you have similar issue. Just let me know if I have helped you...
thx it worked

Hi
In case you still have you HOS can please make a photo of your 'repair' (meaning the wire placed on the contacts)?
I tried what you said and it didn't work, maybe I'm doing something wrong.
Thanks a lot
OK, this is the only thread on the whole internet that make sense ..tried the hardware fix, soldered the U shaped wire on both ends of antenna metal in phone... didnt work...
trying something else--
is that your IMEI?
No.. The imei is fine and 3g is working great.. It seems some problem with WiFi partition or radio... I will try flashing both AMS confirm
Sent from my GT-I9100 using xda app-developers app
THANKS!!!
I tried everything on this thread: androidcentral dot com about "htc-one-wifi-problem-connecting" (google it - this forum won't let me post a link)
and then some...
I stripped some 20 gauge speaker wire and made the U shape. No soldier either. Works great. Thought I might have to tape the cover on since it popped off a couple times the first couple days, but it's seating fine, now.
THANKS!!!
Use WiFi Analyzer (free app) to check your signal with the squeeze test to avoid what happened to munnibhai (and the thread above might be useful if it isn't a hardware issue).
Worked for me as well. More of a mini-pancake shape of fine copper wires worked best for me.

I did not 100% understand the first post or the attached picture.

My GF's HOS isn't able to find WIFI connections (no signal is detected). Could I fix it?

I don't have the back of my phone anymore. I needed a new phone and when I got it it was missing the back to the top. Is there any other way to boost the wifi signal? I literally have to sit in front of the router to catch a signal it is extremely frustrating. Any suggestions would be appreciated. Thanks!

3G cell reception issue and fix

I just want to write this post maybe it will help anyone that has or will have the same problem. I looked all over the internet and could not find a fix, so here is my fix. Hope it works.
I work over seas on oil rig sites (remote locations) so I talk to my wife and family back home via different VOIP apps so its important to get a 3G signal, usually I lock WCDMA only network and get at least 1 bar which is sufficient. All of a sudden I started experiencing very weak 3G signal on my phone, weirdly this was at the same location where it had full bars in the past. This only applies for 3G, I could get 2G signal no problem.
In other areas that I know had good 3G signals and towers were close, it would work alright outdoors but once I get behind a door or a window 3G disappears even if I have it locked. I put in my sim card in my old Galaxy Nexus and it had 3G indoors with no problems at the same place and right next to the N5. So I started testing with both phones right next to each other when I lock 3G with the same SIM the Galaxy nexus would get 3 bars while the Nexus 5 would get the empty triangle (emergency calls only).
I couldn't get out of my mind that I dropped my Nexus 5 a hard drop, but I have a rubber case that took all the shock and the phone didn't get a scratch on it. This was before the 3G signal starts getting funny. Couldn't help but feel that I broke it somehow though. I felt like this might have got something loose inside. What didn't make sense to me is that if the antenna didn't work it wouldn't get 3G at all, indoors and outdoors.
So Step 1, I assumed it was a software issue. I went through a painful hard reset. To my surprise it still had the same issue afterwards.
Then out of desperation I saw this dude's video on how he couldn't lock GPS until he opened the back of the phone and found that the GPS antenna was not connecting straight.
youtube com/watch?v=K1-uCIb-t8I[/url]
So I started searching for where the 3G or 2G antennas are on the N5, but couldnt find anything that points that out. The phone was worthless to me like that so... I took a deep breath and decided to open the phone. Keep in mind, i'm an oilfield engineer and I still had a feeling i might [email protected]#k the phone up, specially that I did not have any tools with me.
So I watched this video on how to open up the back cover:
youtube com/watch?v=mkbmtu-1KSQ[/url]
and went through this guide on what's inside the N5:
theregister co uk/2013/11/05/nexus_5_teardown_shows_a_light_touch_thats_easy_to_fix/[/url]
Then I opened it, couldn't find anything to do, except maybe clean the minor dust off and blow on the ICs a bit. There is alot of pins that connect to antennas located on the back cover itself, so I closed it up, made sure its closed tight and all the pins touching, put in my SIM, and GOD DAMN!! IT WORKS AGAIN... I was getting full bars 3G!!!
So what I figured is that when I dropped it, one of those pins moved a little bit away and broke the connection between the antenna and the IC. Works great for the last 5 hours, solid connection.
Hope I would help anyone with this

Thats nice , but lots of ppls have the signal issues with nexus 5 , and it isn't antena disconect for 90 % if us. I have separated the phone many times. , done about 5 hard resets's tried diffrent verions of radio's diffrent ROM's etc... nothing work's. Frineds have nexus 5 2 of them , and they can get 3g and 4g when they want, and i can only get Edge which is 2g. which is unusable..... I noticed that i have 3g only when i am in other towns, but not mine home town.... I tried diffrent sim cards, and diffrent netowrks, nothing seams to get the 3g at home, plus the gsm sucks, it interupts the calls.. So i must be the frequencies of the working 3g network in mine home town ? Then how i don't get 4g ? Why other ppl with the same phone, and same network have 3g when put next to mine ? NO one knows...
Same Issue
i am having the same issue, just having "E" Edge and cannot connect to 3G/4G, done everything to resolve the issue, took apart the antenna part of my phone but all the connectors and wires are intact, did hard reset several times, tried different ROMS including stock ROMS, tried the *#*#4636#*#* selected all the Radios but no luck, used 2 different sim cards but no use, same damn "E" in the status bar, APNs are all in place, nothing is wrong with the settings so far, dont know wots da problem with this set.
Please help us.

Nexus 5 wont receive 3G or 4G Network signal(Fixed)

A day ago i came through a issue with my nexus, as i connected my charger to the phone, the phone went into a bootloop and wouldnt get into recovery,fastboot,bootloader mode the fix i found on some thread on xda was to remove the back panel and then reattach the battery circuits. This worked exactly as described the phone booted properly.
But since then my nexus wasnt switching to 3G signal, i wasnt sure if it was my sim/operator failing to provide signals, finally after a whole day returning from job i realized that its my nexus thats not connecting to 3g and not the sim operator as i tried using my sim on my mothers phone.
I couldnt find any fixes on the internet and so I went through the internal hardware specifications and from ifixit i learned that reconnecting the antenna wires solved the issue for me.
ive attached the image below for reference on what im actually talking about, ive seen many people suffering with the same problem hope this helps, please do let know if this helped :fingers-crossed:.
Thanks & regards

Problems with reception

Hello.
Bought this OPO recently second hand. It sadly had an issue with connectivity. It has really bad reception 99% of the time, no matter where you are. Below -103 dBm and is rarely usable at all.
I have noticed though, that it sometimes gets really good reception with +HSPA, but then it switches to 3G, and the reception dives to < 100 dBm (most often unusable). It does the same when roaming on the 2G-net - sometimes good reception, but most often really bad.
I have flashed different basebands, but didn't help, so I expect it to be a hardware issue. Does anybody have any idea, what it could be? I can fix most things myself, as long as I know what the issue is and where to get the spare part.
Thanks in advance!
Okay. So I haven't actually been using 4G a lot, but I got around to testing it yesterday. It seems 4G isn't affected by the problem, since it holds a 4G service really well. But as soon as it switches to 3G/+H, the reception drops dramatically.
Same problem here. I have tried many ROMs but the problem isn't solved. Now I am trying to flash .img files one by one and I will tell you how it goes a few days later.
...
Hello again,
After flashing all .img files one by one it still didn't work. The problem was that the previous owner of this phone had the IMEI changed. So I found a guy to recover its original IMEI and now it's all fine.

Signal issues/Bad Reception

Hi guys, I'm struggling to get a decent signal on my OPO.
3g barely works, I get 4mbps DOWN and 1mpbs UP when I'm lucky but most of the time it just doesn't work.
I'm using the latest official LOS 15.1 Rom and I tried all the modems in this page: https://forum.xda-developers.com/oneplus-one/general/firmware-modem-oneplus-one-t3462214 but they all resulted in the same problem.
I've also tried many other ROMs, downgraded to stock cm13s, but nothing seems to work.
The opo is now 4 yrs. old but I feel it could live for so much longer if I can fix this problem.
Does anyone know the cause of this problem?
Have you taken it apart and ensured that the antenna is tightly connected?
And that note, the antenna itself might need to be reseated just to provide a better connection to begin with.

I just did that but it didn't improve. I can't really tell if the antenna pin is making contact with the antenna when I'm putting the backcover on, but I noticed that the battery is a bit puffy, is it normal?
I had a broken battery and replaced it. The old was very puffy and my Phone did not even charge any more. But after the replacement i got Signal issues. Maybe i damaged something? And so did you?

Discontinue use IMMEDIATELY. A puffy/swollen battery indicates that there is an internal leak in the battery and can be dangerous. Do not risk it, turn it off, do not use it and replace the battery (or have the battery replaced). It is possible that the battery is creating pressure somewhere or is causing something to slightly disconnect and that may be the cause of the issue. It can also simply be another problem, this varies from phone to phone.
Yes, it was the antenna connector. After disconnecting all cables from the mainboard and lifting it up i was able to connect the antenna back. Now i have perfect signal and a New battery (which needs to be calibrated some how now).
