On cynogen mod roms it is possible to show what your signal is in numbers next to the signal bars. What is this? How does it work? and what would be considered a good signal? Thanks for the help!

Basically your signal is measured in dBm. http://en.wikipedia.org/wiki/DBm <-technical explanation
The higher the number (it is negative to start with) the stronger the signal. Usually in my experience -70 was good and -104 was bad.

Does anyone else experience a decrease in signal reception in their DUAL? I have a Nokia N95 8gb and I get a strong signal (5 bars) compared to 2 bars on the DUAL.
KS
As long as you can speak clear, I dont think there would be a problem. Probably the N95 shows full signal in areas where HTC can show 2bars but still take the full signal
The best way to test is by making a call in poor reception areas on both the devices and see which one works better or the same.

signal
i had that alot and i bought a signal booster from ebay which has made a diffrence it gives me two strong bars where befour i had one which came and went. they are only 2.00 and stick under the battery hope this may help.i am with orange and also have an n95 which has a good strong signal at home.

yup, that helped me when i saw that on another thread. if you're not using the higher speed internet, it's a good tip
shame the "auto" is biased to faster data networks - i'd like to have it search for a more applicable signal only when you need a data connection
Right sounds abit strange but basically at times I'll have no bars at all, but will still be able to make a call.
And other times it will show 3 bars but I won't be connected to the network.
The reception bars seem to have no relevance on whether I'm getting any network signal.
I'm using leomars rom, is it possibly a software issue.
Does anyone have anything similar?
I'd just like for the reception bars to be accurate, i.e if I have no reception then show no bars, and if I do then show bars
Thanks
edit I've attached a picture showing what I mean, it shows no bars but as you can see I've got a data connection so I must have signal.
hmm, i may have something similar...
when you say no bars, does that mean that they are greyed out as opposed to white bars... or no bars at all?

Sorry my fault, I didn't explain myself correctly.
Yes I mean greyed out, e.g no white bars. In the picture on my first post I've got no white bars so apparently no reception but I've got a 3g connection and can make calls.
And here is a picture showing that I have a few white bars (reception)
Yet I don't have any reception at all. No 3g, and can't make calls
It's so annoying, I've never had anything like this on any phone I've owned before.
When you have no signal at all, you'll get the circle icon thingy instead of bars. Bars all greyed out mean that you just about have a signal (an extremely weak one!) Go to Settings > About phone > Status and have a look at the signal strength details there

Ah ok so that I can deal with.
But what about when it shows a few white bars but then says I'm not connected to the network, so no data connection and unable to calls?
Signal shows -113 dBm 0asu (not sure if that's good or bad)

Could it be a problem with your carrier? Congestion at your local mast could easily cause this.

That's bad! Good signal is a small -dBm figure (so for example -99.dBm would be much better) and high asu.

Thanks for the explanation regarding how the signal figures work.
Going back to what you mention about having white bars and not being able to make calls being congestion. Is there no possibility that it could be a software issue and I actually have no signal but it still shows bars.
Or is it a case where if it shows bars I definitely have signal but likely to be congestion.
Sorry for all the questions
Not sure to be honest. What I have first hand experience of is that when I was with Vodafone, there were big congestion issues in some parts of London and although the phone was getting a full signal, it was unusable (data wouldn't connect and calls would drop) the only solution to at least being able to make and receive calls was to manually switch the phone to 2g only and forget about 3g during the "busy" hours...
Edit: their forum was also full of people complaining about the same problem in other parts of the UK too...

On a slightly relevant note i highly recommend this app.

I've got another question regarding the modems, in another thread someone mentioned that if you are having signal issues it's likely down to the incorrect modem being used.
Now generally all I do is pick a custom rom, flash it and then use the phone as normal.
But should I be picking a rom and using a specific modem version?
Thanks again

Apologies.
I should have known, it's pretty obvious but I'm a bit stupid at times...
Does anyone else notice that the LTE signal on this phone always seems on the weak end? For example, with the T-Mobile cell site about 10 yards away, my LTE reception is -90-95dbm. When sitting that close with my AT&T iPhone 5 (work phone) the signal is about -75-80dbm. What gives? I also notice that the phone does hold onto weak LTE signals, but I am seeing weak LTE signal more often than not. I have seen a -115dbm-120dbm LTE signal. Yes, data still works, my only concern though is that the battery life is getting sucked out of my phone?
Running stock, T-Mobile also likes to show 5 bars for a -109dbm LTE signal. That couldn't be more of an exaggeration could it? Also in my tests, I have noticed if you set the phone to WCDMA only, the signal is a lot stronger.
Anyone care to comment on this?
No issues for me. Even in the factory that i work at i am getting 4G LTE over people with ATT and its quite strong. LTE Tower is a good distance away.
Have you rooted or flashed anything? If its 100 percent pure stock, ask for a replacement. Or even re-flash the latest update to see if that helps.
The only issue i have and others have is where the outgoing data arrow constantly lights up but no data is coming in. I think its a T-Mobile programming bug in 4.4.2 as the issue didn't exist in 4.3 on my S4.

Yes, but on average what is your dbm? Not going by bars.
T-Mobile also does not have a dense cell grid in my area which could be why. Already past the 14 day return window. Absolutely no device modification has even done.
I'm at full 5 bars on LTE 4G signal strength @ - 97 dBm

Appreciate the response. Been doing some research lately, and I think its because t-mobile doesn't have many sites in my area. I don't think their frequencies travel far either. Maybe I am wrong, but wouldn't this cause very low LTE signal?

If the towers are far from you, I would think that would cause a weak signal.
You can try this app.
It may help to see where the issue may be regarding towers, etc

That app just shows the -dBm as a widget. Anyone else notice a -109 or less signal showing 5 bars?

It does give you a more accurate signal bar strength indicator consisting of 14 bars and not 5 bars, as the stock indicator does. I'm at 11 bars.

Ahh. I will have to check the dbm. I don't get full signal but i get like 2 bars. Sometimes four depending where i sit. Then outside, i get full bars. I'll double check the dbm outside with full bars. It should be in and around the -90s.
Hi, everyone.
Could someone help me with the signal strength issue I'm having with one of my phones.
I currently have two I605.
One (white) is rooted with unlocked bootloader with latest CM11
The other (Grey) is rooted with locked bootloader on stock MJ9. (4.3)
I'm using both on Lycamobile on Tmobile network.
The white one is working well with the Lycamobile.
The signal strength is -69 dBm with 22 asu on HSADPA.
I see the network as Lycamobile.
However, my grey phone's signal strength is bad.
It's -90 dBM with 11 asu on HSPA.
THe network is listed as T-mobile on this phone.
The APN settings are exactly same.
The phones are next to each other in the same house.
I have never had problem with the WHITE one any where,
but the GREY one won't connect to the network intermittently
because of weak signal strength outside. I'm not talking about the data.
The phone simply doesn't call or receive calls.
I'm wondering if there's a setting that I should be touching additionally
to unleash or unlock more bands in this GREY phone.
I'd appreciate any insight.
Thanks.

Aosp roms more accurately read the signal strength. The tw rom is reading lower but it just not as accurate at displaying the correct signal strength. It is strictly visual though. This is perfectly normal. Neither phone has to something wrong with it.

Hey, Thanks for the reply.
I'm not talking about the signal antenna icon.
I know that one is strictly for visual. Some shows Full Bar even when it's -100 while some shows 2 bars for the same condition.
Are you saying that even the signal strength reading in dBm is strictly visual as well?
Because I used various signal strength apps and they all show poor strengths in the "poor" note 2.
And I'm curious why there's a discrepancy of showing HSPA vs HSDPA, and Tmobile vs Lycamobile
when I'm using same phone, same cell tower, same service.

Yes it's visual in there as well. Aosp is supposed to read more accurately.I just heard time and time again not to focus so much on those numbers as tw has just as good of signal strength as aosp it just doesn't look like it visually.
Hello everyone.
I have my Z5C set to LTE(Preffered)/WCDMA/GMS.
I have very mixed signal strength when on this mode, but when I switch to GSM only, my signal is full. Does is work in such a way that when I drop LTE, I switch to GSM with a higher signal strenght? (I'm in a small town, I get about 11Mbps down / 13 up)

The way Sony display there signal strength is weird.I can swap my sim between my backup device and the z5c and the actual db is not far off but visual bars are usually one bar lower. I don't think I've ever seen it full signal actually..
I've noticed the same thing. I think it may just be that your LTE signal just isn't as good as your GSM signal. I keep mine set for WCDMA preferred for my best signal, figuring it is plenty fast enough and best for battery life.
