[Q] Gingerbread signal bar color - Nexus One Q&A, Help & Troubleshooting

I have just updated GB 2.3.3 onto my N1 and noticed that the color of the signal bars changes between white and green from time to time.
I have tried monitoring whether there is a pattern by switching data on/off and 3G/2G, but am unable to observe why the change of color.
Can someone please shed some light? Thanks.

If it is green you are connected to the google servers.

In the nexus s forum, some did some digging in the source code for this algorithm which determines whether white or green, Google server connection or not. And it seems some type of number is generated using the signal strength combined with the connection to the server, and the number chosen was 50. So when this number goes below or above 50, it turns green or white. 50 seems like a poor value to chose. I'd love to compile a kernel and test different thresholds.
And yes, the official changes state green or white indicates connection to Google server or not. It doesn't mean you won't have data access, just Google server is disconnected. Seems flaky.

Grey edge icon

Hi, ocassionaly I can see that the Edge icon on my Diamond turns grey (it's shadowed) - never seen this state before, anyone know what it means?
I also have been getting that. I dont think it matters if it's EDGE, GPRS, 3G, or HSDA as I have been getting it with 3G after a soft rest
when I put a 3 SIM card in.. in place of the H icon I get an icon that looks like a mountain... triangle.. what's that mean? any ideas?

Triangle means roaming - so beware the costs!
When it's grey, means that it's not "Attached"...
Bye
I kept getting a "Grey" H icon and I actually found that I couldnt connect to the Internet. Also some of my texts wouldnt send and I couldnt make calls either (not sure if its related or not)
The only way I found to solve it was to switch HSDPA off, now I get the 3G symbol but its not "Grey" anymore and everythings working fine.
this is issue is also reffered as "black icons issue". have a search over this forum and you will find many reports of the same.
No, that's not true. This is completely different issue.
Also it's not true that the gray icon denotes unattached GPRS. For unattached GPRS, there is no extra icon, you just see the aerial icon instead of small letter inside the "signal strength" icon.
The grey state is weird, never experienced before on any device, and it's not explained anywhere so far.
I couldn't find it right now (though I'll still search it), but I've changed a setting yesterday and after this, the "grey" icons appeared. Untill then I had the "filled"/normal ones. That setting is for telling if the data connection is ALWAYS available or only BY REQUEST/ON DEMAND (from an application that needs it).
As soon as I'll find it again, I'll post it here.
i disabled the GPRS auto attach and the grey 3g icon started to appear...no longer the filled one...
I have the same problem since yesterday with edge on my workplace: big grey "E" icon, and it's impossible to connect to the net. But I have 2 or 3 network bars and a little "E" in the top left of them. At home I have HSDPA and no problem
i have a grey 3g icon... only came on after i disabled the GPRS auto attach function in advanced config...
I had disabled that function too. I've just re-enabled it and soft reset but I see no difference, it can't connect in edge

I had an isue a long time ago.
When I disabled/detached my GPRS, it was detached from my provider, ie it was detached on the mobile central.
Only way I could get it working again was to call my mobile provider to have them enable it again.
Yeah but it works on 3G and HSDPA, it's not the same parameters?

This is correct. Grey means Gprs/Edge/3G/Hspda is available, but not necessarily attached. When you connect (fire up a browser/mail/any other internet proggie) it will go black (and a lot bigger and uglier I might add). It's a bit confusing cos when you disconnect, it STAYS black, which is probably a bug.

Service icon won't refresh

Upon some reading of the user manual, I have decided to edit my post.
The service icon on my Tilt (shows the big E, 3G, H, etc), which also shows the wi-fi radio and whether I'm connected to a computer, has stopped refreshing itself.
After starting up, it shows the opposing arrows with an "x" indicating no service. I do have service, though. If I do anything (activate wi-fi, connect to a computer, etc), the icon changes to that, but once done, it stays there. It doesn't refresh back to the big H (or E) that should be there, nor does it go all the way back to the no service indicator.
The most recent thing I did before this happened was to try a registry tweak to remove the clock (and hopefully put up the battery meter) in PointUI Home 2. Even after undoing the tweak, the icon still doesn't work.
Any and all help is greatly appreciated.
If it helps have things make sense, it's the big connectivity icon, not the little service icon with the bars.
If I connect via wi-fi, when I turn off wi-fi, the icon stays the same. If I connect to a computer, when I disconnect, the icon stays the two opposing arrows. After a soft reset, I get the two broken arrows.
Regardless, I never get the E or H I used to normally have.
Help anyone?
I tried installing JUVS's Large Title Bar and while the small icon on the title bar wasn't right, the large icon for the connectivity was the large H I've been missing. I do have the small H with my signal bars, but have not had the big connectivity H icon (or E or G) for a couple weeks.
Does anyone have any clue?
Is the lack of suggestions due to things not being clear, or is everyone actually stumped?

Gray bars and Green bars? What in the world?

My friend and I both have N1's there are times that his radio bars are green and sometimes gray. I have not seen this with mine yet (just got it today). I only have seen gray. What would these color differences indicate?
http://forum.xda-developers.com/showthread.php?t=970098
yeah green = connected to google servers.
grey = disconnected from google servers.
Thanks Guys
Wanted to bump this. I am having this same issue, and my bars go from green to white especially after unlocking from standby. When they are white, I can't connect to anything even though I am connected to wifi at home? This issue is REALLY annoying. Anyone else dealing with this or know of a fix? Sometimes it randomly changes while I am using it. The only way to get it to go back to green is signing into google talk, which sometimes takes 3-4 tries with server connection errors in between. When I am at home I have little to no internet connection via cell, and gprs is all I can connect to, which is why I use the wifi at home. I just don't understand why I can't use the internet if the google server is not connected, and why it drops the google server connection constantly. I should be able to use wifi for browsing apps even if its not connected to google???? Or am I wrong. Please help.
Thanks
(I am running stock, and the phone is not rooted btw..thanks)

try changing your wifi sleep policy to never...
settings--> wifi or whatever--> press menu --> sleep policy --> never
that SHOULD fix it when you're at home... outside i don't know since i dont use data.
cheers!
You're mixing cause and outcome. Your WiFi doesn't work at home, or your phone doesn't want to work with your home WiFi - that's the reason you can't connect to internet, and that's also the reason why you're seeing grey bars.
I have started having this problem this week too. My WiFi is fine. The browser connects and loads pages fine. My connections are now always grey/white instead of green regardless if I'm on WiFi or 3G/2G. All Google services do not work. I am not receiving push emails nor can I force sync in the Gmail app. I've tried to connect by opening up Google Talk but it closes right away. My WiFi sleep policy is already set to never.
My phone is running stock 2.3.4, unrooted.

white and green WIFI icon

What does it mean on GDX x device?
Most of the times I see green signal strength in the wifi icon but this morning I noticed that after trying to establish connection it went white. At that moment I could not surf anywhere.
This afternoon I wiped my device and on setting up I saw that white signal once again but I had no trouble connection this time. After a while it went green again.
What's the colour code telling us?
As far as I know the icon becomes green when your google account is being synced with google servers.

Colored settings icons?

Has anyone else seen this on their phones? Sometimes my WiFi and Data come up colored orange instead of the normal white.
Seen it for the first time today...
Yea my WiFi and data show up orange all the time. I'm not sure what it is but I think it has to do with the network changing and the small gap of down time if WiFi needs to reconnect. It never stays orange for more than a few seconds or so for me.

Gray = Not connected
Orange = Connected - No Activity
Blue = Connected - Activity
When I connect to my work's Wi-Fi, it remains orange until I log on.
It means you're not connected to Google services.

Thanks. Coming from an S4, things are different enough that I'm not sure what's "normal" behavior on basically stock Android. I've never seen the Blue, just the White or Orange.
