Lower signal strength after flashing Carbon ROM on D800 - G2 Q&A, Help & Troubleshooting

I just flashed Carbon on my AT&T G2, and I've noticed a drop in signal strength. I used to get around -80 dbm, but now I'm getting only -100 dbm. This is coming from CleanROM with a full wipe (system, data, cache, sdcard).
Had anyone else noticed this?
Other than that everything else seems to work very well. Enjoying the AOSP experience on this beast of a phone.

Download speed drops daily

I don't have a reason for this. Every day or two I have weird 3g issues. My signal, while actively pulling data, will drop to 1-2 or even no bars. And my download speed will be as low as 60-150 kbps.
Now here is the weird part. If I wipe cache and dalvik through cmw my signal goes back up to 4 bars and download speed is 1500-1700 kbps...
I am running the new stupid fast kernal but its been doing it beforehand. Stock tw launcher with all bloat removed. I did have voodoo of at one point but since has been totally removed.
Any ideas?
try using jt's superclean and look in the dev section should be in page two or three for a thread for fix 3g download speeds it is by geeknik
I saw the thread but the results seemed mixed. some said it fixed it some said it got worse
There have been leaked documents about a supposed maintenance update before froyo and there is definitely a new radio in it that may take care of some of the shoddy signal. Not that this has anything to do with your issue. Just FYI

[Q] 3G reception dropping very low intermittently?

A VZW macro-antenna was recently placed on the building across the street from where I work, and for the first week after I returned from Christmas vacation, I'd have a solid 3-4 bars all day long. Since doing more extensive ROM/kernel modifications to my phone, I notice that my reception will jump around a lot... 4 bars, 1 bar, 3 bars, 2 bars, 4 bars, 1 bar, etc.
Using a signal widget confirms that it does actually vary quite a bit... such as suddenly dropping from -86dmb to -106dbm, then bouncing back to -86 without the phone having been moved.
Has anyone else experienced anything like this or have any idea what might be causing it and what I could try to alleviate the issue? I suppose I could go back to the adrynalyn's 12/12 test kernel (the one that came with DJ05), but as I'm currently using both Voodoo lagfix and sound, I'd really rather not have to do all that.
Currently using Superclean 0.9, JT's 1/23 voodoo5 + lagfix + sound. Thanks in advance for any assistance!
I dont have exact DB measurements but I can tell you that just sitting at my desk at work my 3G connection speed varies from 1mbit to 10kbit in about 4 seconds sometimes. The network just dies. It slowly builds back up to 1mbit and then dies again. Pandora streaming is annoying.
edit: after 4th try of *228 option 2 i now am getting better signal and 1.8 down and .6 up....maybe verizon was having issues in my area and now they have it fixed...we shall see

I have had problems using that kernel (Superclean 0.9, JT's 1/23 voodoo5 + lagfix + sound.), with my cell signal dropping out entirely at random times.
Once I went back to the previous kernel I was using, everything was fine again.
How long have you been using your current kernel?
Im using adrynalyns latest i think ...with voodoo and voodoo sound fix...for about a week now....i've tried just about every kernel i could find but still had the same problem. *228 has done the trick so far......my signal is low but is constant....its no longer dropping to 2g at least.

I thought the 3g to 1x problems got fixed with DL09 (stock rom) but it still appears to be a problem when I get in a low coverage area. My friends HTC Eris with the same low coverage still maintains the 3g while my Fascinate starts to switch to 1x and won’t grab 3g until a reboot or at least 3 bars of coverage are present. I tried *228 several times with no luck. Any ideas?

Factory Image flashed to AT&T Nexus S now has weak 3G

After flashing JBQ's factory image for sojua, I have a very weak 3G signal. To the point where app downloads that were instantaneous are now unacceptably slow, moving at about < 30kb/sec.
Is anyone else seeing this? I've restored and reflashed several times. Is this the reason AT&T hasn't released the OTA? JBQ said that these factory images are exactly the same as what AT&T would release OTA...
Edit: It seems even wifi isn't that great.
I have not noticed any issues on AT&T. I'm getting full 3g bars where I got full 3g bars before. I also flashed using the factory images. I assume you are on UCKJ1 radio?
Yep, UCKJ1. I'm visually getting full bars too, but the actual speed is much slower.
What speeds are you getting?
-87 dBm 14asu strength
Network type jumps from HSDPA:9 to UMTS:3
Speedtest.net app:
1017kbps down
303kbps up
418ms ping
It could just be network conditions. I just tested and I'm getting around 3500 kbps down.
It's possible I suppose. I'll have to check later and see if it improves.
I had issues with the UCKJ1 radio too, speeds were a lot slower for me than the KB3 radio. If you can, try flashing a different radio and see if that helps. Rolling back to KB3 worked fine for me.
I'll give that a try. It's lame that I should have to though.
Hmm. K3B shows even worse performance, and downloading apps throws error code -101.
Have been experiencing this as well, just restored a nandroid of the 236->ics update and its a negligible difference between that and the factory image, both using xxkb3, I'm thinking it's just network conditions on att.
I'm going to revert back to 2.3.4 and test. I don't believe it's AT&T because it has been the same for two days and wifi seems sluggish too. It's almost unusable.

Weird reception issues?

So I've had the phone for 2 weeks now, and I finally activated it yesterday. To my dismay, I am not getting reception in the common areas of my house. I'm on T-Mobile and their coverage map says that I should be getting "Good" reception in my area. But it seems like the reception just goes in and out. If I am using my phone in my hands while sitting on the couch in my living room, I get no reception. However I left the phone sitting on the couch and went to get a drink, and when I came back I had received 2 texts. Wtf?
The same thing happens in my room. When I'm leaning against the stairs to my loft bed, I get no bars. However, if I move literally 6 inches to the left, I get 3 bars to full reception. What's the deal?
And when I say I get no reception, the phone is showing a "hollow" triangle, like with black as it's background. Is that normal? On my old phone that ran ICS (CM9), when I had no bars, it would show a gray triangle with a little X in it. I was getting this hollow triangle when I had no SIM card in it, so I thought it was odd that it shows the same thing when I have no reception.
Any ideas anyone?
I've noticed that the reception on this device can take a nosedive when it is held. And yes, when you have no reception it is normal to show the hollow triangle.

Huh, thanks for the reply. I'll try holding it differently. And thanks for letting me know, I wasn't sure.
I've been having the same problem. I drop signal a lot even when its just in my pocket. I'm starting to think the radios in the N4 just suck

I think I would have to agree with this. It's so weird. Like sitting in the same exact spot, I can go from full signal to no signal in a matter of seconds. It's really actually beginning to get in my nerves, and I'm wondering if I have a bad unit.

From past experience with TMo, 2 year subscriber from 2003-2005, and just signed up for the $30 Monthly plan, their coverage just plain sucks. I'm in a good coverage area according to their map too but I get 1 bar in my house, -109 dBm (measured with Network Signal Info) while my Verizon phone gets -60 dBm, and full bars. I took my phone outside and I had to walk half a block towards the main street before I got a decent signal, -90 dBm and was even up to 3g data speeds, no HSPA+. However, this is still an improvement from my previous experience with them as I used to have to take my phone a mile up to the Interstate to get a signal (I live in a medium sized city by the way mentioned in a TMo commercial). I'm looking at purchasing a signal booster but haven't decided if I want to go that route or just switch to StraightTalk running off AT&T's network and see if its any better.
I should also mention that at work, in a different town, inside my office I get crappy reception, 1-2 bars but if I go out into the hallway 5 feet away I get 4-5 bars. The signal strength fluctuates all the time so not sure what is going on, maybe a lot of interference from wireless devices.

with my previous phones I never had an issue keeping a signal (s2, amaze, sensation, g2x, gnex) but with my N4 I can't even keep edge for too long without it dropping. and I get the gray signal bar thing a lot too. aside from that i love this phone its perfect but its just not worth it if im at risk of missing callsthinking about trying ST at&t or maybe trade someone on cl for a note 2.

Yeah I almost always get the gray signal bars. It seems like edge takes forever to kick in. When it finally does it's reasonably fast (at least compared to my old Virgin Mobile phone that averaged 10-15kbps on a good day) but it just takes absolutely forever.
But for example, right now I'm sitting in the dining room in my house. The signal bars are hollow. A couple of minutes ago, I went to the kitchen, set the phone down on the table, and when I came back, I had gotten a text message! I just can't comprehend this.

are u on stock? i recently flashed project cold fusion (cm10 based) and i immediately noticed my signal both WiFi and data/voice were stronger (or showing more bars anyway). i wont be able to fully test this theory till tomorrow at work, where my signal has been dropping like crazy on stock ROM. but its something to consider trying if u havent already
Sent from my Nexus 4 using Tapatalk 2
I've noticed these issues in areas with low Tmo reception. One minute the phone will have 3 bars and the next it will be the hollow triangle. I don't have any of these issues at my house because I get a very strong edge signal.

Mine is strong wherever I go. From my college to home I get no less than 2 bars. I live in a small town in NC.

Yeah I'm on stock. I was planning on flashing ParanoidAndroid this weekend though, I'm REALLY hoping that improves things. This is just so frustrating.

H is better. E means you're on edge (2g) which is slow. When you're on H you should be getting at least 3g speeds and sometimes much more.
Sent from my Nexus 4 using Tapatalk 2
Ugh. I've only seen H for a short time last night. I get E pretty much all the time. Just another reason to hate T-Mobile and this phone now.

I'm on AT&T, using a MEdia Net plan and have been getting weird connection drops on HSPA+. I haven't ever seen the phone go on EDGE, so I can't comment about 2G connections.
It's seems like the phone just drops a connection randomly and frequently. I can't even stream NPR anymore. On WiFi, the connection is flawless. I didn't have his issue a week ago, and I've flash many different ROMs since then. I not sure if this is a modem issue or an AT&T network issue. My account still shows that the N4 is recognized as a plain old dumb phone, so I don't think that they've restricted my access, but knowing AT&T, any annoyance is possible.

T-Mobile does suck when it comes to hspa coverage. They have soooooo much edge coverage. Unless you are in a city you're quite likely to be on edge.

My connection isn't great inside my house, but is LTE quality a hundred yards from my house. Still get better in house reception than the ATT iPhone 5 living here. If there are a lot of tall buildings around and you live in a solid structure your signal will suffer.

I used to have T-Mobile but switched to straight talk and don't have any issue. According to T-Mobile coverage map, I should have sorry voice coverage and excellent data coverage yet it was the other way around. I dried then the other day and love having a constant signal now! T-Mobile just sucked where I lived, AT&T/straight talk is awesome

I'm definitely getting worse reception on the Nexus 4 in my home than I did with my Nexus One. I have a weak signal at home, but the Nexus One was able to hold onto it. The Nexus 4 goes in and out. The Nexus 4 is also worse in other places that I regularly go, which have weak signal. I've missed quite a few calls, in the couple weeks I've had the phone. That pretty much never happened with the Nexus One.

Stock vs Custom Rom signal is low

Is ti common for the signal to be lower on a rom vs stock rom..
Im using cloudypro and my signal is very low and sometimes actually alot jumps from lte to H to 3g
When i was on stock i had a constant 5 bars and so does my wife s4
Its always the case for me. I think its just cosmetic though, I haven't noticed a drop in signal while talking
