[Q] Problem with signal bars in AOSP ICS v3 - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

(Screenshot attached at bottom)
Hi,
For some reason, the reported signal strength is completely wrong. This doesn't effect calls or anything but it will always show that I have full signal.
When I go into settings you can see that the value reported is very very high as well.
Due to my low post count, I can't ask in the actual thread but I did I search and no one else seems to have the problem.
I've tried a full wipe, and flashing the latest radio (LP1) but problem persists.
Does anyone else have a similar problem, or know of a fix ?

Well it says you are on GPRS which I don't think would have very good signal? But you should know that AOSP roms show your DATA signal on the bars.

I've just walked outside where I get full 3G, and the problem still persists.
Confused as to what is causing it!

Help with signal

I keep losing my 3G at work where it used to be full bars all day. Now it seems to be one or two bars and it drops to 2G most of the day now
I flashed the new radio but have now gone back to 26I as I thought it could be that. I am on Cyan's latest - reflashed after a full wipe.
What could be causing this? It seems no matter where I am the 3G signal is dropped throughout the day.
Has to be the radio or ROM?
Could it be the APN settings?
Is this a rom specific issue?
I don't know if it's a ROM issue or not. I haven't seen any faults in the cyanogen thread about this...

[Q] Fringe area modem? Dont care about data.

Is there any modems that seem to work better in areas of poor reception?
I frequently loose signal or can only receive texts but not reply to them in Southern Utah. This is even on the I-15 corridor that supposedly has coverage all the way. Heaven forbid I drive off-road and need to use my phone with reliability.
Obviously with that kind of reception I am not going to be doing any web surfing, but it would be nice to be able to reply to the texts when they manage to get through. I don't mind flashing a new modem when needed, I understand sometimes the trade off is power/range versus battery life. I carry two spare batteries anyway.
Coming from a WinMo phone we would have all sorts of radio options. I gather in Android they are called modems and the options seem more limited?
Anyways, any advice on a particular modem that works well in fringe areas?
I am running Firebird2 kernel so I believe I need to stick with a I9000 compatible modem? Currenty I use the UGJK4.
Really? Nobody uses their Captivate as a phone?
I have downloaded KP1 and JL2 and will try them this weekend I think, but I cant be the only one living in BFE that has this snazzy phone.
Someone may be interested in my test so far so i will continue to talk to myself here.
I switched from the JK4 to the JL2 modem and have had a dramatic difference in signal bars. I now get a bar or two at the ski resort base where as before I never had anything. It reads 'emergency calls only' instead of 'no service'.
I still cant send any texts out and am unsure if I would be able to receive any. I think the phone needs to ping both ways to get a text.
I am unsure if the 'signal bars' mean anything about the sensitivity of the modem but its interesting that I get them now.
Next time I will try the KP1 modem for the weekend.
Im in southwest USA and the UGL2 modem works wonders for me.
what about the battery for jl2 and jk4, can you compare them as well?

Just a word of advice, make sure you check the actual signal strength (db) because bars can lie badly. The only reason I say this is because it "says" you have more bars but you still can't text sounds kinda like you're getting an over exaggerated bar signal strength.

Is there a *# code that will read out your actual signal strenght? I have SGS Tools installed and can use it to get to that information if you know were its at?

I carry 2 spare batteries and swap them out as needed so I am not sure about battery life. At the ski resort it pretty bad but probably due to the constant wifi usage more than anything.

You can get your signal strength (measured in dBm, so you want a lower number) in Settings, About Phone, Status.
The service mode accessed via *#0011# will also show you that signal strength, as well as some more info. (RSCP, received signal code power, corresponds to signal strength in the Status menu above.)
Good luck.
sgs tools provides more than information... Its a shortcut to all your hardware codes. I'm in batch 1007 and when I flash stock ---> custom rom... I always have Data issues. JK4 modem Serendipity Speedmod... Toggle my bands and for some weird reason my WAP jumps from stock New York WAP to a more local WAP (Kansas or Chicago) and my Data goes wild (latency lowers dramatically and speeds return to normal)... Otherwise my phone is a paper weight.
So I flashed the ZNKP1 modem this weekend and tried it out. It seems about the same as the last modem. However I did notice something interesting with it.
At the lodge I get full bars and no service! It will hook up to what I assume is the tmobile network? The signal shows -95dbm and 6 asu but the service state says out of service.
I am guessing that might be why I can get signal bars on some of the lifts but be unable to send or receive calls or texts.
I had been under the impression that the signal bars were only for networks that were usable but I guess that is not really the case.
Is this a function of the modem not being stock or is it always going to pick up and show unusable signals?

I've tried and tested just about every modem, and I always come back to JK3. For me it has the best battery life and reception. GPS is also important for me, so this one seems to do the trick (with Adam's GPS fix).
JL2
The new JL2 modem works best for me, drops less calls than JK4
and consitantly has more bars.
Also my gps works better with JL2, my captivate is revision 1007
I switched my ROM to Cog 4.1 so I will have to see how it works for me at the resort next time I go.
But does anyone have any clue about the signal bars indication I mentioned? Full bars but on the wrong network?
Is that something I have never noticed before, or something to do with flashing different modems?

WCDMA problem

I'm having this issue with WCDMA in which it constantly drops to 0 signal bars from full signal, and sometimes I even get disconnected from the network until it decides to jump to full bars again. This happens on all locations, ROM is stock XXLSC deodexed (got it from the user I9000 here in the General section) and the problem just keeps repeating itself. Signal drops completely, then jumps back to full, then fully drops again after a short period..it's extremely annoying since I can only use the slow GSM network, which is useless to me when I need fast internet. I called the network operator and they say they had zero reports on an issue similar to mine, so it's not them.

Maybe you should try another "modem" file or test another real stock Rom.
XXLSC isn't a stock Rom - it's based on the XXLSA leak from sammobile.com with the two OTA updates I got on my device. So it has bugs and you should see it as early beta.
after upgrading to JB i used to have similar issue.. loss of signal.. call quality issue.. i changed the modem to one for my location and it has improved a lot. You could try that too

My phone was recently in the repair shop because its usb port was busted up. Ever since I've got my phone back, I have this issue and the technician guys are baffled about what it could be. They just changed the connector and nothing else, I don't see how that can cause any issues with the reception. It keeps loosing signal every few minutes, only to jump back to full bars.

I'll just switch back to stock 4.0.4 and see if it helps, but I'm still quite sure that my phone worked fine with XXLSC leak for a long time.

Update on the situation......I gave the phone to the official Samsung service shop, they tried everything, from changing software to cleaning/changing antennae connectors, and nothing fixes the problem. Most likely I'll have to get the motherboard switched, which costs about 210 euros. Pissed beyond belief right now, would rather just throw the phone away.

Call problem when on 3g/h/h+

So, this is my problem... I have a regular international factory unlocked n7000. And when im in 2g+3g network mode(hsdpa+hsupa) my calls keep droping after a minute, couple of seconds- no significant patterns... I think it could be beacause of the network signal change (weaker or stronger signal- from h to 3g or 2g) . when im on 2g only everything is normal, no dropped calls...Curently im on PA 2.99+ rom and lsc modem , but even when i was on gingerbread and ics i had such problems... I tried different kernels, roms, modems...
I even had that issue on my i9100...
Does anyone else have similar problems, and a possible solution?

[Q] Nexus 6 Random cellular signal loss

As the title says, Its been better now its worse, my mobile signal disappears leaving me from full strenght to empty triangle without any clear pattern. Calls, data, nothing works so its a geniune signal loss not a software bug. I was on LRX21O > LRX22C > LMY47D > LMY47I and latest is the worst.
I cant remember having this issue on 5.0 but early lolipop is plagued with bugs. Any ideas what might be going wrong and how to fix this? Its really frustrating....
thank you in advance community
I tend to have the same problem, but its only been mobile data for me, I have sprint.

I have a similar issue. When I attempt a phone call in my basement, I get "no carrier available". I can go upstairs/outside and initiate a call, go into the basement and the signal is fine. I suspect it is a radio problem that Google needs to fix. I also cannot send mms with photos-no matter where I am. Pretty darn frustrating for this over-priced phone.

General consensus is a software bug. Happens when switching between different LTE bands and different towers, regardless of carrier. Signal won't actually drop, but ASU jumps to 99, then corrects itself. This causes the signal bars to drop to zero, then back up, but signal stays connected the entire time. Would be nice to be able to revise the way that android reads that and not drop bars for it each time. Either that or have the ability to force to a particular band/tower to avoid the switch. Annoying, but looks worse than it actually is.

shows no signal but stays connected? Hard to believe, when my N6 drop signal I cant make a single call at all, is it part of the bug? Also the link you pasted doesnt work, please repost, I'd like to know more

Sounds like you may have something else going on if you can't make calls.
I have the same issue and it cancel calls even when I'm talking. Before Google's updates for that bug called stagefright it was awesome and without problem but now it seems their update aren't match carriers datas.specially for us in Asian countries because our carriers have no contact with google
I have the same issue as this, and I asked before:

Signal Loss
Same problem with my Nexus 6P on Verizon. Cellular signal is lost and only restored by rebooting the phone. Happens 1-2 times daily. I'm on Android 7.0 build NBD91V.
