CyanogenOS 12 on Oneplus One, often losing signal and data - ONE Q&A, Help & Troubleshooting

Since I flashed the OTA for Oneplus One that gave my CyanogenOS12 I'm having problem with my signal and data connectivity.
When I lose the signal, it's like impossible for the phone to get the signal back, and I often have to reboot the phone to get back to a signal. Yesterday even that didn't work.
Something like that has happened to me before, with a reboot needed, but now it's much more often.
Are there someone else that having the same problem like I do?

No. I'm in Sweden.
Turns out a lot of people having this issue with the LTE. Turing LTE off and it will work better. It's just like when the phone drops the LTE signal the first time, it has huge problems getting back to a signal at all.

[Q] WTF??!! Dropping calls even after returning to stock??!! Anyone else?

I thought this was a ROM issue. but now i realize the DAMN PHONE is just loosing signal!
AM I THE ONLY ONE WHO IS DROPPING CALLS ON THIS PHONE?????
If I am not, why am I not seeing this subject being talked about here???
(sorry, i am so pissed)
What ROM's have you tried? And what baseband are you on.

Baseband? I have no idea, sorry.
In my experience, this phone just can't keep a signal. Seems to actually be an issue with switching bands failing.

I just realized that (I think) it's a DEATH GRIP issue!
Signal changes dramatically based on the way U hold the device!!!
anyone else?

That's a side issue.... the death grip causes the phone to get weaker signal, which causes it to try to jump to a different band (if there's a stronger band available)... in my experimentation it's not actually the weak signal that causes the g2x to lose signal, it's a failed attempt to switch bands. I can be in an extremely low signal area, but as long as I'm locked on 2g only or even WCDMA only, as long as there's signal I don't get random drops. As soon as I put it on automatic in a low signal area, it drops signal constantly. It's the switching. Your picking the phone up has simply affected the signal in such a way that it starts trying to jump bands to a stronger signal.

Nexus 5 cell reception issue?

Anyone using a nexus 5 on T-Mobile in the NY city area getting very bad reception I'm not sure if there's an issue with the device or tmobiles service coming from an HTC one that had excellent reception I think there might be something wrong with my device

Are you getting excellent HSPA+ reception, but the phone isn't switching to LTE or connects to LTE, but jumps back to HSPA+?
Go to a T-Mobile store and tell them about your situation (don't chat with them online because that did not fix my situation). The rep that I spoke with called tech support and they did some sort of reset on my account. I also asked for a new SIM and was given that new ISIS SIM. As soon as my phone booted, it was on LTE and stayed on LTE. I was like you, thinking that my device was messed up, but T-Mobile fixed it.
No if you check the discharge chart I posted the phone is just completely loosing service but I haven't tried getting a new Sim yet I'll try that and see if it helps

The problems you describe were while using T-Mobile on a Nexus 5? I've only had T-Mobile service about a week now, before that I always used AT&T on samsung android phones (S4, Note II, etc). And service was always very strong on AT&T.

Anecdotally, I'm having terrible reception in NYC as well. At home and in the office, barely one bar, frequently none.
Over the past 2 years on an HTC Sensation 4G, have typically had no reception problems in these same areas - 2-3 bars at all times.

We have the same issue with Nexus 5 with Tmobile in greater NYC metro area. When i tried with my old Samsung mobile there is no issue and it works fine. The problem, I can't make and receive any calls. Most of the callers told me, it goes to voice message after couple of rings. I didn't get even single ring and voice mail message. Frustrating Nexus 5.
My friend and I have the same problem too.
Both 16gb White
What colour of nexus 5 you guys have?
I see some have white, maybe white causes this issue??
Having the same issue as well. I have a 32gb white model and I randomly lose all bars when my friend calls me. It is very random and only happens a few times. Going to go and switch out the SIM from T-Mobile and have them reset my line and see if that fixes the problem.

32GB black with miserable cell reception here, so not a color issue.
Maybe an LTE issue? Might explain why our old devices got better reception, if they were using older gen signals/antennas? Not that we'd want to in the long term, can we disable the LTE services and live off the previous gen, at least to test?

I get lots of complete dead drop outs too, even on Wifi. One moment cruising along, the next I'm disconnected, the next I'm back on. Something is not right with this device.
Hmm I need to also find some time to visit a t-mobile store and check out why my reception just drops and gets spotty all of the sudden sometimes.
I have the 32gb white model. I never get LTE while two of my friends with Nexus 5 that were next to me both got LTE.
I also had my signal drop to 0 in a starbucks before, and I never had that happen with my previous Nexus 4, was frustrating since I couldn't get the promo code for my starbucks reward drink x.x
Ok guys Google is definitely on its game with replacing your your nexus 5 placed my RMA Sunday night got it today and I can report my new phone is working as it should I wouldn't say it gets as good a signal as my one did but a minimal difference that you would expect between two different devices so if your having an issue call up Google tell them you already spoke to T-Mobile about your service issues and they couldn't help you and that your certain its a device issue as a side note their RMA process has you basically buy a new device and send them the old one
Also I had a black 32gb so I don't think the color matters

After my research, When we switch back to 2G (GSM Only) option there is no issue with voice calls but the data speed is very slow as expected. It seems that there is an issue with T-mobile towers LTE/3G/4G for voice calls. Below is the problem with Sprint network, looks like same thing happening for Tmobile.

If you need voice calls high priority like me, give a try to switch GSM only.it shows E network on signal bar.

Nexus 5 dropping me off Network ??

So I got my nexus 5 on Friday and its perfect none of the mentioned defects was having some small issues with the notification light but that's all. However I noticed once a day since getting it I go to use my phone and it says emergency only / Rogers and I won't be able to make calls or receive calls. Anyone else experiencing this problem ?

I'm on Rogers and I get this too. I usually fix it by going into network mode and change it to 3G and back to LTE immediately.
I still get incoming calls even though I can't dial out until I do the above change.

I have the similar problem i'm on rogers and if the signal gets weak it will show signal strength in the home screen, i can surf the internet(data), but will not send text messages or make calls, if I try to make a call it say "cellular network not available", if i turn air plane mode on then off it reconnects right away. this has never happened with my GE Galaxy S4

I have the exact same issue guys, I hope that it has nothing to do with our nexus 5's.
im getting this error too. darn! its not normal for a phone to be like that. never happened to my previous one.
there must be something wrong with the phone.
im on Fido.
but its only happening to canadian network? weird.
maybe they're torturing people who didnt buy from them? lol
It looks like I have a similar issue.
My connection sometimes gets lost. Some sort of hiccup when connected to mobile network.
No issues found on WIFI
I'm on a hspa network in Canada and wanted to report that I get worse reception with the N5 than I did with my Galaxy S2. I hope it is easy fixable with a new modem flash or other update.
Just wanted to contribute in case there is anyone working on this and wanted some more info.
I had to change my data plan because, according to T-Mobile (US) it was not compatible with the phone. I could get emails and SMS text messages but could not get Internet data services (kept being prompted to log onto the network and presented with the T-Mobile logon screen). Lost my unlimited data, which I was grandfathered into (but found out that they were throttling me at 5 GB which I don't usually hit). I knew they would eventually make me change my plan anyway and was able to get a new 4.5 GB plan at the same price. Since T-Mobile will be offering this phone very soon (tomorrow? they're taking pre-orders now), I guess a lot of long-time customers will be pushed off their unlimited data plan.
I have the same problem!! It's really annoying - mine gets dropped every 2-5 mins! Is there a way to fix it? Is it the N5 or Rogers network?
I have the same problem in Belgium:

If you are constantly getting poor signal it might be the handset. If you have good signal, and can use data, but have "Emergency calls only" instead of a carrier name, it's probably a carrier issue.
I am on Fido and have randomly had the same problem. There's another thread somewhere, and most if not all people reporting the problem are Rogers/Fido customers.

I also have this problem. I am on Fido in BC. Sometimes it will completely cut off the network signal from full bars to no service, similar to no sim card installed. It goes back to normal in about 5-6 seconds by itself but its definitely annoying.

[Q] Signal drop/No service

Just wondering if any one else gets this, sometimes my signal just drops out and I get no service.
Then it comes back it does not happen all the time, I live in a big city Leeds infact so signal is quite strong.

I'm on AT&T and have the correct APN settings and have called AT&T with my IMEI. I have significantly worse signal than with my HTC One X. I am not comparing bars to bars, but rather where the signal drops completely. In places where I had low signal but still connected I now have nothing.

T-Mobile on stock ROM i had my first signal drops.
I was fine (or at least never noticed them) from the time i got my phone (day one) without any drops here in orlando.
Drove over to Tampa/Venice Beach area this past weekend and noticed some drops. Had about 6 drops according to my battery stats in 2 days. i had good to excellent coverage the entire time except when it would drop comlpetely (outline of signal bars)
would connect in a couple seconds, but i noticed over night, it would drop for a pretty large amount of time (like 10-15 minutes at a time.)
Mmm defo seems like were all having the same issues, wonder what it could be
Sent from my Nexus 5 using Tapatalk
I had this issue too, and here's how I fixed it:
By default LTE is enabled, meaning the phone will periodically scan for a LTE network. If you're in a big city, you're likely to find one. Your phone will attempt to connect. However, it fails, meaning it will have to rescan the HSPA bands to connect back. That results in a few seconds of no service. Why can't it connect to LTE? Because by default, the APN is not the LTE APN, for Rogers at least. I'd assume AT&T would be the same. You can test this by dialing *#*#4636#*#*, selecting phone info, and selecting LTE only. You'll see that there is no service. I tested this in an area I knew had great LTE coverage, and that led me to the conclusion that it's LTE causing the signal drops.
So how to fix? Simple, just change your APN to the LTE APN for your carried. To do that go to Settings -> More -> Mobile Networks -> Access Point Names. If you're experiencing this issue on Rogers, change the APN field to ltemobile.apn. If you're on another carrier, you'll have to search for their LTE APN configuration.
After doing this your phone should start connecting to LTE again, and you won't get those annoying signal drops.

So yeah the next update will probably fix the issue. It's not so bad in the meantime, Lightflow sill notify you that your nexus has lost signal, and you still get the internet and incoming calls.
We're not alone. Supposedly Google is "aware" of the issue.
i've hcanged my setting from '4g' to '3g' to see if i notice a difference (hopefully will) then when 4g is released or i get a 4g sim, can move it back up
Yes, I'm having issues too. The real problem is the fact that I have a Wilson cell booster in my home (supposed to have up to 5000 square foot range) and my n4 had full bars most everywhere inside. With my n5 It shows 1 to 2 bars if I'm lucky and quite often drops to none! The only way to get full bars Is to stand right under the indoor antenna. Not impressed, and I sure hope this is fixable!

Running 4.4.2 so the latest update did nothing to help the problem as far as I can see and I have messed with my APN settings. On AT&T.

Appreciate the speedy reply. Hope Google gets on this fast. I also have LTE connection issues which has plagued both this and my original device so I am pretty sure its a radio issue. The phone loves to stay on HSPA+ even when there is a decent LTE connection: it's last in the pack to connect to LTE and first to disconnect when compared to others on AT&T.

My N4 with a combo radio sticks to LTE a tad better than my N5 with stock radio. Sadly, morrislee hasn't fiddled and combo'd N5 radios, and I'm not sure they've been tested and sussed out like the N4 radios. Citing the fact some with issues have flashed all the radios so far with minimal success means we wait for Qualcomm, after Google kicks them in the you know where.

Phone doesn't reconnect to LTE after dropping to 3G?

Anybody else having this issue? LTE works fine until..it doesn't, and then even if I was getting LTE in the exact same spot, it never jumps back on it. Once it's in 3G, it stays 3G until I restart. Any way to fix this?

You are in a area where they have not fixed circuit fallback. ... they made the phone do this so you would get calls and text ... triband phones use cfbs to push through calls so if your connected to lte you will not get calls and text.

I get what you're saying, but I don't believe that's it-- I stay on 4G most of the time, but once I get a call and it shifts me back to 3G, it never moves me back to 4G after the call. It just sits on 3G until I cycle airplane mode or restart the phone.

Actually, if you read, it's not. If I wasn't in a CSFB market, then I wouldn't connect to LTE at all except for a moment, and then drop off. I do connect to LTE, and receive calls without a problem. But let's say I pick up my phone and walk into another room where the LTE signal isn't as good, and my phone drops to 3G-- when I come back to the good LTE reception room, it should reconnect, like my previous phone would. Instead, it doesn't. It has nothing to do with CSFB.

Ok well good luck getting help fixing this problem with an atittude like that. Since I've had this phone, I mostly see 3G but with my S4, I never saw 3G. I can get it to be on LTE all day long when det to LTE only. Its something to do with 3G/LTE hand off and the single band data/voice radio.

My "attitude" was simply to correct you, since you either didn't read the article or didn't understand what I'm talking about.
I can agree it's probably something to do with the hand-off and/or the radio/how aggressively it decides to change connections, but that's not CSFB.

Anybody else having this issue? LTE works fine until..it doesn't, and then even if I was getting LTE in the exact same spot, it never jumps back on it. Once it's in 3G, it stays 3G until I restart. Any way to fix this?
Click to expand...
Click to collapse
try clicking airplane mode, and then back off...that should reset it
i randomly run into this...but most of the time it gains LTE
