[Q] Connection goes up and down after replacing screen - Nexus 5 Q&A, Help & Troubleshooting

Hi everyone,
I have recently cracked my screen and replaced it myself using youtube tutorials. I have (somehow) completed the task although I had many problems with the two side cables (black and white antenna cables, I hope you know what I mean as I don't know their proper names). Specifically, I wasn't able to slide them down the channels intended for that and at the same time I wasn't able to connect them properly in the jacks were they need to be plugged in. I thought I have somehow did it but it seems I did not do it properly as I do have frequent ups and downs with the network signal, I lose it constantly in places where I used to have full network signal and I can't reach LTE at all, there's no connection at all when switched to LTE. There's signal only when 3G is ticked in settings and internet signal remains to E, rarely if ever moves to H.
At the same time, Wi-Fi is good although I feel it worked better previously, but that can only be my imagination working.
So, I think it has something to do with those cables, as those were my main issue during reassembly. Is there any advice anyone can give me. They don't seem broken, but I can't fit them in the channels and in the jacks properly. Would it work if I put something like a sticky paper in the channels to hold the cables down. Also, is there any trick for connecting them in the jacks or I just need to be precise?
Or, is the problem something completely different?
Any advice would be much appreciated as my phone is rather new and I absolutely love it.
Thanks in advance

Those mini-coaxial sockets can be a bit harder to push in at times - just get a pair of good quality tweezers , get a good grip on the connector and push it down with some other tool. I can guarantee it is going to go in . If they don't make good contact you are either going to get intermitent network , or a very week network signal .

External antenna/signal boost?

Hello! I'm looking for a way to boost my signal. I've noticed that when I have under 3 bars (and even if it bounces up to 3 and back down) my battery drains quicker than it can charge. At work as long as I have 3+ it will charge faster but if I'm at a different spot and its under 3 it drains. Also, it heats up (usually hangs out around 98.6 degrees but sometimes it'll go 105+). My main reason for wanting a boost at home is because I tether to play games when my sisters hog the house connection. So I'm looking for a cheap way to boost my signal. Small repeater sort of thing or something. To my understanding the little spots under the cover allow you to plug in external antennas, so where can I find everything for that? (And yes I saw that people can't get signal back after)
THANK YOU

We used to live in an AT&T dead spot (yeah, yeah, who doesn't?) and ended up putting a powered wireless repeater in the house with an external antenna on the roof. I believe the manufacturer was Digital Antenna. They're not cheap, but the wired versions (if you can live with that) are a bit cheaper.
As long as you have high speed internet at home get an Airave. It puts up a tower in your house and processes everything over your home internet connection. 5 bucks a month i believe.

Problem solved.
I thought about airwave but people ten to not pay the internet from time to time xD and does the signal crap out if people use the internet? Its only a 768 connection (country ftl) and people tend to netflix and cam -_-

The airrave uses your internet connection for 3G data and voice calls. If your internet is slow to begin with and ppl are hammering it all day long the airrave won't work well for you. Also, it doesn't hand calls off to the real cell network, so if you're on the phone and you leave your house the call will drop. If you have good signal outside and bad signal inside, one of those repeaters is the way to go - but it ain't cheap.
Dang ok. What about something like the Wilson Magnet Mount Cellular Antenna at Radioshack? (Its on the site. Id link it but you need 8+ posts >.<)
I'd just limit your sisters ip address/mac address with a QOS policy, so that she can't hog all the bandwidth. (would be done at your router)
I've heard and seen on this board some nasty results from connecting external antennas to the connection point behind the battery cover. Do a search in the forums to see, I can't remember exactly off the top of my head.
Ya I only saw a couple people mention problems and it seemed to be things that they had only heard
Whatever you do DO NOT CONNECT an EXTERNAL ANTENNA to the CONNECTION POINT.
So far, everyone on this forum who has tried so with a Galaxy S has ended up with some permanent baseband (or whatever is responsible for the gsm/cdma part) corruption. What ended up happening was that the internal antenna would turn off. In some cases it meant that they could only call with the external antenna plugged in, and in other cases is meant that neither the external or internal antenna would work. (note: This has happened only on captivate and vibrant so far, so I am not sure what will happen on CDMA but.... Better safe than sorry right!?).
oh and sorry for the large font.... It catches your eye... ~_~

lol I did that when i got my first smart phone, the htc touch. Thankfully back in those days sprint would fix any problem or give you a new phone no questions asked for 55 dollars. ( I used to find inventive ways to break my phone. Like the mentioned external antenna, or a homemade battery back)
I'm interested in a solution to this as well, preferably something that doesnt have a monthly fee attached.
In my basement, I get about 1-2 bars of service, and sometimes nothing at all. Is very frustrating to receive texts up to an hour late.
talk about ad placement
This came up right under the latest post in this thread:

[Q] HTC ONE S Wifi Problem

I have a HTC one s and it is experiencing wifi problems. I know the one x has had some of the same issues, but the problem with my one s is that whenever i hold the device from the top, the wifi drops suddenly and it than cuts off. When i remove my hand about, 5 seconds later the wifi shoots up to 4-5 bars.
return it and get a new one
That's where the antenna is!! Your SIM cover has the antenna built in to it.
Please use the Q&A Forum for questions &
Read the Forum Rules Ref Posting
Thanks ✟
Moving to Q&A
Try to remove and reseat SIM card cover, if its still too bad have the phone replaced. A friend of mine had his One S replaced after we compared Wifi signal with Wifi analyzer and his was ~20 dBm worse than mine at same locations. New one is fine. Didn't know about the wifi antenna on sim card cover back then though, might have helped since it seems it has for some users here.
I have almost the same problems with WiFi antenna although it's not as worse as others are saying. I can confirm though that when you put your hand next to the SIM cover the WiFi signal drops 1-2 even 4 lines at some times. However I don't think it's a manufacturing defect for some phones but I think it's a general problem with all the models. I am saying this because I had the exact same problem with all my HTC devices (Diamond, Desire and One S). So I think it's a poor WiFi project and maybe cheap raw materials rather than a poor WiFi in some phones. In a way it's normal that this happens because your hand will screen the antenna. Try to do this with all antennas out there and you will see that your hand (your body) will influence the signal in all devices). So if they couldn't overcome this problem they had to put the antenna in the place where you will cover it most rare, and this place is on top of the phone. I don't like it either but that's the way it is.

just noticed the same this morning, though only happens when i try to wrap the upper part of the device with my hand. i never hold the phone in that position so it does not happen.....
Actually when you are browsing the internet, view pics one-by-one, view movies - usually you are holding the phone in the landscape mode so most people will rotate the phone counter-clockwise until it reaches landscape mode and will hold it with the left hand exactly from the upper part (if the phone is rotated clockwise then the supporting hand will accidentaly touch the lower 3 buttons so not too many people will rotate it clockwise) and with the right hand they will browse. So in these situations, which come very often, we will loose (almost all) signal. If these will not bother you/me/all of us, for sure it will bother all of us when browsing internet. I really don't know if a fix can be made for this issue. Even if I would change the SIM cover (so change the WiFi antenna), the replacement will be built exactly the same so the problems will persist. I am curios to see if SGS3 has the same problem or not. I really think it's a question of antenna position so it's a crappy board design of the phone. It shouldn't happen at a 500+ euro device.
I have the same wifi issues on the One S. There is a firmware upgrade available OTA, it may fix it. I will see.
Any chance this is fixable or not device-wide? It's somewhat of an annoying problem when holding in landscape. I'm assuming this is no more than a design "flaw"
I'm having the same issue. When holding the phone in landscape mode, the wifi signal drops to one bar.
I noticed that when I'm closer to the router, like within a 3 meters range there is no signal dropping.
It's very annoying...
Could it be fixed by improving the contact between the antenna and the back-cover?
Sent an email to htc support about it, this is their response:
The location that you describe, on the side with the Power button near the camera lens, is where the HTC One's antenna is located. Covering this location will provide less-than-optimal results with regard to cellular and WiFi signal. You may want to try holding the device slightly to the side of this location, more towards the center of the device.

Did you guys try remove and reseat SIM cover? Might help a bit even though its natural with some signal loss when holding it that way. If your phone has significantly worse signal when laying on a table or whatever compared to another phone then try to get it exchanged. Compare with https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer

traffic stops after few minutes
Hey,
my signal is ok, but after few minutes of working the internet connection just will not go through anymore. I have tried installing 4.04 but no change. AP is still connected, full signal, but not even google comes on. Restarting wifi helps for another few minutes. Doesn´t have to do anything with sleepmode, that I am sure of - it happens even during download from Play Store i.e.. Wifi best performance ON, Keep Wifi on during sleep Always.
Any idea on what that might be? - the old HD2 (android 2.3.) works like a charm on my home network
Getting desperate , otherwise such a nice phone.
WIFI problems
Ive been trying hard to figure out the flash 1.85 thing and have had no luck. any way someone can help me with exact directions on doing it. i have downloaded 1.85 2.85 files but having issues flashing it.
please help

[Q] Signal and Antenna layout / schematic

Hello,
Firstly I'm looking for a comment from an expert who has taken Nexus5s apart before. Also I'm beyond the point of returning the phone as this fault developed after replacing a screen and ribbon cable (after I smashed my phone badly). Any help or advice would be great.
So since screen and USB flex replacement on my D821 i notice that my phone signal will connect with full bars, then drop completely, I can also only get 2g where i was able to get higher. The same sim works fine in my nokia. The Wifi Signal is fine and gps works ok but the 'no service' thing makes my phone unusable. I have tried making sure all contacts are clean and even replaced the loudspeaker unit and the black antenna cable but to no avail.
Can someone put up a picture of exactly the components that are involved in the phone signal / 3g setup? Is it possible something could have been damaged on the mainboard to cause this? I can search for networks, connect (sometimes) then it will just cut out.
I tried google for days but cant find a schematic. Basically im trying to determine if there are any other parts i should try exchanging before giving up. It makes no difference how i hold (or dont hold) the phone.
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.

Calling works sometimes, no network available most of the time

My original OnePlus One worked great in my area, my Moto E also get's signal all the time so this is not a network coverage issue. I have an OPO that will let me make calls perfectly with great clarity, and then a moment later will say it does cannot find a signal. If left on it will mostly have no signal but after a few power cycles boom there you go, full signal! I would think it was an antenna issue except when it does work I have full signal, not a weak signal like on my old S3 with antenna issues.
I am hoping this is just a modem issue that can be fixed by flashing the latest stock rom/modem but I am hoping I can get some input on the problem.
Thanks for your time!

have you dropped the device? it could be hardware.....too. Have you tried different modems or not? If not that would be a start. (https://forum.xda-developers.com/oneplus-one/general/firmware-modem-oneplus-one-t3462214). If the modems dont help then here what i would check...only if you confident.
Open the OPO and make sure the screws have not come lose as sometimes that can cause issues with signal.
Recently i has something similar but no as bad as you, i ended up replacing the, Speaker Antenna module, microphone flex. you could also replace the coax- i was suppose to be but the one i got sent was too long so i had to stick with the original one.
This is what they ebay guy sent me before i replaced the parts:
first thing to replace is the Coaxial cable (which carry's signal), check both coaxial sockets and the ports on the board it connects to
-Second (like you said) Mic Flex, although it is a tough call between the lower speaker unit and the mic flex as they are equally as likley to be at fault)
the speaker unit contains the GSM Antenna, the Mic flex simply takes the Signal to the main board from the speaker Module.
both would be Ideal unless you have time. speaker unit is relatively cheap.
finally check for any lose connections or wear to any of the Gold inside the phone where it makes a connection, using some wet and dry sandpaper rub the Gold plates Very very lightly to reveal a shinny Gold, some on the mic flex, some on the speaker unit, some on the other flex's,
and finally tighten all screws properly, often the screws can work their way out, pulling the connections away from each other.
I would suggest check the connection and wear to the gold as mentioned if u dont want to replace the parts. I found that the coax on mine has been disconnected on one end so i fixed this but it didnt help hence i ended up replacing the parts.
Service was spotty for me too.. I would have LTE and then the next second EDGE or no service at all. I eventually had to fastboot flash CyanogenOS 13 (latest stock for our device) and start over but it fixed my problem. I have not had a problem since.
