Hey guys.
I have noticed large variations in the signal that I have. E.g., somewhere that I normally have 2 bars, from time to time it may display 5 bars or no bars at all, but I can still make a call.
The real problem occurs after long period on standby, after which it seems not to recognize my sim. It has happened 3 times in a 4 day period. The problem is solved if I restart the device or disable-enable the plane mode, but this is not a real solution, since meanwhile I've missed a few calls...
I have no weird apps installed, and I am experiencing the signal variation since day 1, without any apps installed.
Any ideas? Contact the retailer maybe? I bought it from expansys on April 11th, what is their DOA period?
Contact HTC maybe? Or get a new sim?
Your help is highly appreciated!
I suffer signal variations too, I can go from 5 bard to 2 bars and back all in the same location.. Ive never had 0 bars, or had a call drop. But its something that bothers me
What you should do is
Check with your provider for any faults in your area
Request a new sim
Contact your retailer
contact HTC
All in that order.
I also have this problem. I have tried a new simcard but still problem. I hope HTC will solve this, because it seems to be a software problem.

Thanks for the quick answer.
I do not mind the signal variation, since I can make calls even with 0 bars (!), of course I don't know if this affects the battery life...
My real problem is, not recognizing the sim... I also forgot to mention that the very first time I inserted my sim into the phone, it didn't recognized it either.
I 'll get a new sim from my provider, hoping it's not the phone's fault.
In the meantime, I 'll let the retailer know about the situation and ask about the DOA period, in case that doesn't work.

You mean, just the signal variation, or the sim not recognized after standby?
you should rly try to get new sim card, could be sim problem.
For signal variation, it probably drains battery life. If signal is weak, or it drops from 1 bar to 0, then back to 1 (had this situation at my work) - battery gets drained RLY fast.
But that was in case when I rly didnt have or had rly weak signal. Dont know with this, but I guess if phone trys to "recover" signal, it will consume much more battery

The SIM problem is a separate issue, which you should hopefully get fixed.
Now regarding the signal strength bars. I have used a lot of expensive RF test equipment. Most of it more expensive than your car. Or house.
None of them measured signal level in "bars", usually it was dBm (mW in 50Ohm). Unless you know what those bars correspond to in real power levels, then it's rather hard to say if the variation of a few bars is something to worry about.
Digital comms systems tend to go from "working great" to "no signal" within the span of 6dB. And that's a very small range when one looks at the variation of signal level in a typical urban environment, even if the phone is static (position-wise).
It's been some days now and I don't have any more sim issues, so all good.
Maybe it had sth to do with where the sim was touching the phone... (I tried cleaning the sim and reinserting it a couple of times)
But the signal variations continue... I reached HTC and they said to try GSM only mode, and also safe mode, but same behavior there. - now rechecking and unsure about results, gosh it seems complete random.
aza314, I understand what you 're saying, but what about this... the signal variations are so annoying, that rarely I might unlock my phone to get a temp "no service - emergency calls only" message (normally I have signal again in 1 minute or so), in the same spot I was making calls normally some minutes ago (or later).
Guys, I need your input here... if you have never experienced such a behavior on your phone, if it's not a known bug, I need to know, in order to report it DOA.
edit: on the other hand, maybe it's related to this issue, so hoping to get fixed in the first update...
Because I love my new Nexus 5 so much, I "had" to go swimming with it for about 10 mins until I *realized* it's not water-proof. :silly:
Anyway, I opened it up and did my best to save it. And it boots up and functions again. :victory: However, there are three sequels:
1. LCD display shows water streaks in the background and the contrast is bad but can still see;
2. The vertical center line of the touch sensor doesn't seem to work; Elsewhere works fine;
3. Very weak WiFi reception and hardly be able to connect to any wifi network unless it's in the proximity of the router.
The first two problems can be "easily" fixed by replacing a new digitizer/screen assembly. But the #3 is the most critical issue. If it's not fixable, this phone is pretty much useless to me.
I've read that many people complained about the weak wifi issue on Nexus 5. But mine was very good and always had strong signal before it went swimming. I've tried cleaning up the WiFi/BT circuits and even made sure to have the WiFi/BT antenna on the back cover to have good contact with the contact pin on the main board. But still got weak reception.
Has anyone had similar issue and how to fix weak wifi reception problem? Or where can I get it fixed?
Thanks a bunch!
Hello guys and girls,
after experiencing some GPS problems (loss of signal on the road and/or late fix) I did the fix found on youtube (Where you place a bit of paper/tape under the GPS antenna contacts). It worked just fine, my GPS fix is now happening faster and I did not lose the signal ever since. But I am now facing some (weird?) problem: My GSM connection (GRPS, EDGE) is really really bad. In my room I don't get any signal at all, outside I get like 1 out of 4 bars of signal strength, but I lose it after a few seconds. I normally have 4 out of 4 bars in my room. BUT: My 3G connection works fine, 3G, LTE, same connectivity as before.
My friends phone (same carrier) does get the full GRPS/EDGE connection in my room, so it's not the carrier having problems. I didn't do any updates or anything in the last weeks. It would be a huge coincidence, if a software bug happened while I fixed the GPS problem, so I assume it's a hardware related thing?
How might I fix that, what possible solutions are there?
Tried the following so far:
Restarting multiple times, with our without airplane mode
Re-inserting the sim-car
Switching between LTE only, GSM/LTE, GSM only
Flashing new/other modem
Replacing the speaker/antenna-module
-> nothing changed
out of sheer curiousity, and after reading your post, im stuck wondering.. why do you want or need your gprs and edge connection when your 3G/LTE is fine? data speeds are very slow, and drain lots of battery using anything internet or download related..
Yeah, sure, 3G/LTE is better and coverage is really good where I live, that's why it's not an emergency for me, but it's very important to get it back to work properly.
I know at least 2 situations where I really need GSM (GPRS,EDGE):
1) At work (huge metal building, no 3G/LTE, only GSM) -> I can't call, text or do anything with my phone (don't worry, I am allowed to do so and no, there is no WiFi)
2) On the road, especially the german autobahn has large areas where there is no 3G/LTE coverage, so I can't use my navigation-software properly and can't respond to calls or whatsoever
So all in all: GSM in really important for me. Please help me. :crying:
ahh.. I see.
and your GPRS/edge was fine before the GPS "fix"? maybe something got loosened?
Before I did the fix it worked perfectly fine. Directly after I did it, the gsm was gone so I figured that I somehow damaged the antenna. But since I replaced it and nothing changed I am not sure what to do now. Are there other antennas, are there other modules that influence gsm, that I might have damaged or loosened?
That's what can happen when you tinker with guts of your phone. You risk damaging or messing it up. Sorry, I don't mean to sound like a jerk.

Yes, dave2metz, I know. I was fully aware of that when I opened my phone for the first time to fix the GPS thing. But I am not here for moral advice.
Any ideas how I could fix my problem are highly appreciated!
Edit:
Just checked: The sim-card is not the cause of the problem either. I would really appreciate some good ideas guys..
No idea what I might try?
My best guess is that this is a hardware related problem. But how does one fix it? I replaced the antenna (the bottom thing), nothing changed. So that specific antenna was not the cause of the problem.
Are there other antennas?
Are there antenna-connections that I could check?
Any other hardware things that I might check?
Anything that might have lost the physcical contact inside the phone because of that GPS fix?
Could it, against all odds, be a software problem?
Please, I am really in need of a working phone. If I can't fix it I need to replace it sooner or later because GSM is essential.
If anyone can provide me with an idea or something that leads me to a fix, I will reward you (amazon gift-card or whatsoever).
Cheers,

Did you figure it out?

Did you end up figuring anything out for this? I have something along the same lines. I dropped my phone and smashed the screen. I was able to get a guy to replace the screen portion of the unit, but immediately after I got it back it had no cell reception. Rebooted came, back thought everything was cool.
After a couple weeks I notice my phone has lost reception occasionally. It's now gotten worse, I used to be able to reboot it about 5 or 6 times and then it would randomly come back. I've even had it come back without performing a reboot on its own.
I ended up taking the whole thing apart, reseating everything after having a day and half span where I have been unable to get it back and boom reception came back. Thought it was his repair job at that point, but it has since dropped the signal again and I can't get it back. Yesterday even I was showing LTE signal changing from low to strong etc, but my network was still down as I couldn't perform a search, maps, or anything.
I have my phone apart again. I've checked all the connections over and over and wondering what else to look for or try to replace. True my impact could have damaged a component on the mainboard, but my phone works fine in all other areas. I could replace the antenna wires and the antenna/speaker module, but I'm not sure it just a reception problem.
My phone also boots into airplane mode when it has no signal, but turning it off does not restore the connection or anything. Rebooting it puts it back into airplane mode. *#*#4636#*# shows my radio is off. Thinking it's a short or something somewhere, but I doubt I'll be able to fix it in that case - at least without a mainboard?
That's my other question, what part need to be replaced for experiencing no network and its not the antenna or antenna wires? Is the mainboard? Sister board? Currently researching teardown as this phone is modular and I'm sure I could source the part off ebay or something.
Hi,
There's one antenna for 2G/3G/4G so I think if this problem was caused by hardware, it would affect overall connection to mobile network.
I think that this might me software-related problem but actually can't figure out which. Only thing I'm currently thinking of it that your phone has problems with connecting to certain GSM band. For example in Europe are 900 MHz and 1800 MHz standard for GSM.
Lower frequencies bring you better coverage. Your phone might have trouble with connecting to them and automatically selects 1800 MHz layer.
If you are able to get another phone with SIM of the same network provider, I recommend you to download any networking app and compare data about cells. Mainly CID number. It's unique identifier of each cell in an area.
If both phones are connected to same cell (CIDs are equal), you have to compare RSSI values. Lower means better signal. RSSI is defined as a negative number in an interval of <-51; -113>. So -75 dBm is better than -89 dBm. In one place should be difference about +/- 5 dBm.
Reaching slightly different RSSI numbers while connected to same cell in same place might mean that your phone really have problems with radio.
hey mate,
My wife phon is having the same issue 4G works, 3G sort of works, 2G nothing.
[Did the GPS fix on my wife's Nexus 5 (and mine) also]
swapped sim, used another telco same issue.
when into service menu did *#*#4635#*#* , click the 3 dots, select radio band - only see USA band.
While my phone had automatic, usa bad , usa band, japan band.
she is running stock rom with unlocked boot loader, I am on CM11 but doubt that should make any difference.
if I work out what is going on will report back.
nexus 5 3g 4g damaged
hello guys?.. my htc nexus 5 got wet and i notice the signal strength got lost. when i open it up i notice the lines on the antenna got damage. how do i repair it? or should i replace it with new one? Pls help !!
Is issue still remaining?
Hi. I am having the same problem. Could anyone find a fix for this?
My GPS was and is fine. I didn't do the gps fix, but I have replaced my battery and I think it happened after the replace...
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.
I've noticed a strange behavior with my T-Mobile V20. It really likes to drop service and then show a loading symbol for a bit before locking onto a signal again.
Usually the current reception is weak (1 bar), but not always. Sometimes it does it when I have 2-3 bars of LTE, just to switch down to 5 bars 2G.
There are also times when it'll show that I have 3-4 bars of voice reception, but the status will say "Searching" and calls won't work. Rebooting will make LTE appear.
Is this normal behavior? I just got this phone, and it's also the phone I used to switch off Verizon. T-Mobile definitely has better coverage where I am, but that's only when it isn't dropping the signal.
I have the same issue with my LG V20 phone. The reception/signal strength is horrible. Callers constantly complain that my phone goes in an out, making it difficult to maintain a conversation. Bluetooth connectivity is also an issue as connecting the device requires multiple attempts. This phone is becoming useless due to the reception and Bluetooth connectivity issues. I will continue to use my Samsung Galaxy Note 4 as a backup. I have never experienced any such issues while using the Samsung device. Hopefully the developers at LG are taking notes and a fix/update will be released before 2017.

I haven't had problems with Bluetooth; in fact, I've had the opposite; Bluetooth works nicely.
I hate to say it, but I haven't actually made a call on my phone yet, so I can't comment on that, but you seem to be having it much worse than I am.

What kind of case are you using? It sounds like you have something blocking the signal (your case), you have multiple, defective radios in your device, or something -- in the area within which you operate your phone -- is interfering with the signal. I am not experiencing those issues at all, and neither is my wife (we're both using US996).
Good luck in any case. Your phone not working correctly is a horrible experience.

I haven't had any problems with dropped calls. Then again, I'm usually somewhere near wifi and make most of my calls that way.

Well now that CM14.1 is for all Snapdragon variants, we've got some new helpers.
So I've figured out at least one of the signal oddities. I'm going from one bar on LTE on T-Mobile to roaming on AT&T. I was able to use the app LTE Discovery to see that I was on AT&T's LTE B17 (which isn't even listed as supported on the H918). The phone was just disabling voice and data.
My cell reception seems normal for tmobile(which is mostly not good in my area) but the weird thing is on bluetooth. When i bend down at work with my phone in my pocket the BT signal get choppy. Like im compressing the antenna or something. Weird.

You could take a look at the FCC test for BT https://apps.fcc.gov/oetcf/eas/repo...on_id=Yart0xj3tUt4f53nf7wvbQ==&fcc_id=ZNFH918
I found out that this phone is rated for LTE B13 from there. Looks like it supports a lot more bands than LG or T-Mobile say, since even the FCC doesn't include B17.
