Do your signal bars fluctuate constantly? - Nexus 4 Q&A, Help & Troubleshooting

My signal can be at 3 bars, then all of a sudden go down to 0 bars, then back up again to 3 bars without moving the phone. I have never experienced this before with any other phone.
My phone has never yet lost signal fully, but it's usually displaying 0 bars. I'm trying to figure out if this is an issue with the hardware of software?
My baseband is .33 and I've tried the .27 baseband and experience the same issue. Device is Nexus 4 running Android 4.2.1. Carrier is Telus.
I've googled and searched but all the similar issues people were having were back in November and December.
Thanks!

same here. on vodafone network. i also get emergency only. sometimes i get full bars and stays only on gprs for hours then....goes back on wcdma by itself.
i think its a radio issue.

Signal strength, goes up and down???

While sitting in my house I have watched my signal strength change from 0 bars to up to 4 bars. this happens without moving or using the phone.
Anyone else ever notice this? I have seen it happen in 2 different places in my house. I have seen it go from 3 or 4 bars down to 1 or 0 and back up again in a matter of minuets. BTW I am on Cingular using Radio ROM 2.19.11

Dropping Signal

Hey there people.
Hoping I've not missed an existing thread.
I'm having problems with X10 dropping its signal seemingly through its own free will. Had phone since mid april and not had any problems with. But the other week me and the missus noticed occasionally i wasn't receiving texts she had sent me. This happened every now and again for a few days. I then noticed when i picked up phone it'd show signal on 3G as maybe 2 or 3 bars then suddenly drop too nothing, showing the little x indicating no signal. After a few seconds up to a min it'd pick signal back up and work again. I no for a fact its not me been in an area without 3G coverage because it happens at work and until this started happening i got a strong 3G signal there. It doesn't seem too switch too edge either any more. Its set too GSM/WCDMA prefered. I'm on 02.
Anyone else have similar problems or any clues on what the problem it.
Cheers

[Q] Weird HSDPA signal dropping issue

I have this weird issue with my hd2 flashed with a custom NAND android 2.3.3 rom.
When its on my bed or desk or whatever it has full strenght HSDPA signal but as soon as i pick it up it drops to 2 bars and then to 0.
It only does this when i'm holding it in my hand, also when i move it around i can see the signal strength switching from 2 bars to 0 and back again.
At first i tought it was the radio but after trying them all and trying other roms i'm still having the same issue!
Switched to 2G only now and my reception is always perfect at full strenght but now im on EDGE all the time...
Did someone here have the same problem and found a sloution by any chance?
thanks in advance!

Erratic modem behavior

At home, we have a Cel-Fi signal booster since T-Mobile reception isn't very good indoors. With the signal booster, there is full reception pretty much everywhere in the house. However, for some reason, my Nexus 4 running stock 4.4.2 keeps cutting out to no signal as shown in the picture (the phone is in the same spot in the house for the entire duration shown). This behavior happens with the 97, 98, and 33/98 radios. Does anyone have any idea what may be causing this? Everyone else in the home has no problems with the booster and I've even swapped out my SIM card but that hasn't fixed the issue. Thanks

Mobile Data will not enable!! (Dynamic Kat)

I need help this is driving me insane!
I've been running Dynamic Kat Rom for about 6 months or so now. Everything was working fine then all of a sudden a week or two ago I noticed my mobile data is not enabling at all.
I can only connect on Wifi and only receive SMS.
I've tried
- Messing will all the data/network settings
- Turning Mobile Data on and off -- no effect
- Toggling Airplane Mode on and off as suggested in some places
- Wiping everything but Data and reflashing latest ROM
- Reseating the SIM card
- several other things I forgot..
I do see the carrier information in the top left (AT&T) and I am getting signal bars.. but not indicator for 4G/LTE/etc
I've been messing with this for a week now and it's driving me insane.. I can't get a connection anywhere unless I'm on Wifi.
Anyone have any suggestions? I'm not super phone savvy, but willing to try any suggestions anyone may have.
Hmmm.. weird.
So I called AT&T and asked them about it.. figuring it could possibly be a carrier issue.
They told me to try things I had already done 100 times.. turn the phone off and on.. turn wifi off... etc.
I turned Wifi off... (which I had done 50,000 times before) and 4G popped up.
I guess they did something. So.. guess it's resolved.
Problem has returned.. same issue. I will have 4G signal for hours and then all of a sudden it will drop completely and I can't get a data signal no matter what I do.
I see AT&T in the corner and have signal bars, so I AM getting some kind of signal.. but no data connection whatsoever.
It seems completely random and intermittent.. I can have data signal for days with no issues then I will lose it for days.
Restarting the phone 5-20 times sometimes fixes it.. but that's about it. Anyone have any ideas what could be causing this?
Bad signal / carrier issue?
Call them and report a fault in your area?
I have called them multiple times, they will reset the signal.. sometimes it will come back right away, sometimes it wont.
And this happens regardless of where I am. I know for a fact where I am right now has a great signal strength. I get 4-5 bars on average. But this also happens at home as well about 20 miles away, which also has a good signal, or anywhere I go really it can happen. This isn't in the middle of nowhere either, it's smack in the middle of SoCal (LA/OC)
I'm beginning to think it may be a SIM card issue or a hardware issue with the phone. I'm going to try asking them to send me a new SIM card.
Another thing I will notice is when I have a working 4G LTE connection, and I'm on Wifi... it will sometimes CONSTANTLY switch back and forth between wifi and 4G like every 10 seconds, even when I have full signal strength on Wifi and 4G.
Disable Smart Network Switching in WiFi settings
it's nothing but a buggy headache, disabling might fix most of your problems, almost certainly the constant switching back and forth
Yeah forgot to mention I have disabled that. It's disabled now. It solves the constant switching back and forth (when I actually have a data connection), but that's kind of a separate issue as the losing data connection.
