Hey I was wondering why whenever I make a phone call my bars indicating signal decrease to 1 bar or none and my 3g symbol goes awayt any suggestions?
Currently on calkulins 1.8 rom,
El29 modem and i do update profile and prl atleast once a week, but no matter what modem or rom I am on this happens regardless

3g goes away cause you cannot run data and voice at the same time.
As for it going down to one bar? That could be because you are no longer connected to 3g.
Are you having a problem?
Correct.
When you're on a call, you're using the 1x network and you're seeing the signal strength for 1x. When you're NOT on a call, you're seeing the 3G network and it's signal strength.
What I find REALLY odd is that for most folks, they see the opposite. 1x has stronger signal than 3G.

Can someone please explain how the 3g symbol/arrows/bars work?
I am just wanting to know how they relate with each other.
For example sometimes I have full bars and the 3g arrows are white, not transmitting data. And other times I have low signal bars and thr arrows are moving faster.
So if I have full bars should the arrows be moving all the time or is it just the nature of the beast and it transfers data when it wants to.
Thanks

3G is actually seperate from the phone radio. The bars represent phone signal strength. If 3G (data) is down you can still make phone calls. 3G is like your internet and data. The arrows moving are your accounts and emal syncing.

arrows show send and receive of data packets, they will blink, etc. but that has no relevance on the speed of your 3G connection or the strength.
3G is NOT separate from your phone radio, it is the same radio, which is why you can't have a data connection and voice connection at the same time.

I have googled things on the web while on the phone. Telephone bars and 3G strength are independent otherwise where does 2G and 1X come from? People out of 3G areas still have phone service.

You have not "googled" anything while you were on the phone, at least not on 3G. The outdated version of CDMA Sprint uses doesn't allow for voice and data to be active at the same time.
Yea the 3G arrows are the internet up/down , the signal bars are separate thats your cell signal. Like when you turn off 3G you can still call and text , 3G is for the internet when youre not on wifi , the arrows light up when your phone is sending or receiving data

I stand corrected...it was on 4G. Sorry. 3G and phone share the CDMA Radio but they are still 2 different animals independent from each other and from indicators.

So is there any way to make the data send and recieve faster? Or is it just luck of the draw.

There were slight differences in 3G transfers with the different modems when I tested them on my Airave. EC05 was fastest with EG22 slightly behind. It varies greatly out in the real world on different towers.

I'm hoping this is not a bug, but there have been times when I try to fire-up a web-based app, like streaming music, that I can't get even a 3G connection yet I have multiple signal strength bars. The 3G icon is gone even if I turn Mobile Network off then back on. I don't think I had this problem with my EVO 4G using 3G. Is it just because it can't pick up on a 3G signal even though I have 3-5 bars?
The Network Mode is currently set to CDMA/LTE/EVDO even though we probably won't have 4G in Columbus until the end of next year. I kind of miss my WiMax 4G. Now that I think of it, I changed it to CDMA only. Maybe that will help.

The "signal bars" have nothing to do with your 3G connection...they only indicate voice call signal strength.
To check 3G signal strength go into your dialer...
Enter ##DEBUG#
Code: 777468
Debug Menu:
Select EVDO Eng RF
Pwr= Signal Strength
Better than -96dBm is a great signal
Between -97dBm and -107dBm is good
Between -108dBm and -114dBm is fair
Worse than -115dBm is poor

You may have a connection problem with your GN2. I had some similar problem. I would taken it in to Sprint and see what they can do. Maybe it's tower upgrades in your area....
Happens to me sometimes too. Just a garbage tower. I have emailed the network guys to open a ticket and they got pissed I emailed them directly. It's a tower issue and no mine is not getting upgraded for a while.

Is there an app out there that would display the 3g or 2g signal strength on the status bar.
It frustrates me i can even search but have full voice service, at least with the signal strength indicator i would understand

I use this one...Open Signal ...it has a widget that will show signal strength also.
I just bought a new S3 for my nephew the other day. Right now he is in his house and has 3 bars for signal but it says he is data roaming? I told him to use his wireless network whenever possible. Why would he have signal but yet be data roaming? Does that make sense?
Help!
Is there a triangle in the signal indicator? (In the status bar)
If so...then he is roaming, and even when roaming the network signal bars still fluctuate

Ok the triangle symbol went away...does that normally happen when roaming (shows up then disappears)?
It shows when roaming doesnt show when not roaming. You can have all the in network voice signal you want and still data roam if the network is acting up. Voice and sms go over 1x-rtt and data goes over 3g/ehrpd/lte and if it absolutely has to 1x-rtt the signal bars show voice signal strength and not data signal strength so you can have full bars and data can still be slow.
I like to break stuff!
I have a T-Mobile Galaxy S4 and at some point yesterday T-Mobile switched on LTE service in my area. Speeds were faster as expected but I also noticed that the carrier signal dropped from solid 4 bars to 1-2 bars after the LTE migration. This morning I noticed that I missed a call that went straight to voicemail and then I wasn't able to reply to a text message (it kept failing to deliver)
So I played with the settings and it's definitely the case that my signal strength is being affected by LTE. When I go to Mobile Network settings and change the Network Mode to "GSM/WCDMA" with HSPA+ 4G, I get 4 bars (-83 dBm) while switching back the default Network Mode "LTE/GSM/WCDMA" brings it down to 2 bars (-100 dBm) - I attached screenshots of the status screen and the service mode.
Should I be concerned about this? Is the poor signal strength just a temporary setback because T-Mobile is still tweaking its LTE network?
Anyone?

When I am home I have little or no LTE coverage, and even though in network its set to LTE and CDMA, it never seems to switch to CDMA even though I have like no LTE coverage at home. I never have more then 2 bars, usually I have 1 or no service at all.
And WiFi calling is unreliable as well. Often it says it's logged in but it doesn't work, it it fails to login and then apparently doesn't try to login again. If I turn WiFi on and off, the WiFi calling usually then logs in.
Anyhow, if I can't get the phone to automatically switch over to CDMA or if I can't get WiFi calling to work reliably, I'm going to cancel my sprint service since my phone isn't really usable at home. I don't want to put the phone into CDMA only since I would have to reboot the phone every time I go outside to get back on LTE
BTW, I get great LTE signal right outside my house.

staying on wifi doesn't really help me since wifi calling doesnt seem to be very reliable. Right now staying on lte seems like a better option since at least i can see when i have no signal. Wifi calling half the time says it's logged in, but it doesnt work.
you may need to get an airave since you aren't having service in the house. Just call up sprint and let them know what is going on and ask for one. Hope this helps!
I'm just worried the airwave well be as reliable as the wifi calling since it's essentially the same thing.
I wonder if there's something in android I can tweak that will make the phone jump to CDMA if the 4g signal it too weak.
I've noticed that if I have one bar and make a call, it almost always jumps to full bars as soon as I started the call. I'm guessing it's jumping over to CDMA. But why doesn't it do that when the phone is idle?

I believe that the bars you see before initiating a call are the data signal strength. When you press the call icon the phone Radio switches to cell 1x signal. which is usually pretty good in most urban areas and that is why you would see the signal bars jump to full strength.
My wife uses WiFi calling at home and it works very well. Maybe disconnect your phone from the router and do a restart/reset of your router. Then reconnect.

Why would it show that if the phone is on wifi though?

I've tried turning the wifi on and off on the phone. That will usually get it to work, but I have no way of knowing if it keeps working since as I said, it will sometimes say it's logged into the wifi calling but not work.
I tend to think it's not an issue with my router since every other online activity works great, including skype or streaming 4k videos on Netflix

The Wi-Fi icon is also a signal strength indicator. When on Wi-Fi the signal bars to the right are mobile data, then when you receive or make a call they switch to cell tower reception strength. When I'm on wifi and see only one signal bar next to it I know that I'm on LTE. if I see full signal bars and I'm not ona call, I know I'm on 3G. if I turn off wifi I will see either the LTE with 1 bar or 3G icon with full signal. this is at my house so its always the same and its a easy way to check how the signal strength indicators work on your phone. make sense?

I have two signal strength indicators on my phone. One for wifi, and one for call (or data). So i don't really understand how the wifi icon is also a signal strength indicator since there are two separate icons for that. Why would the phone show an indicator of the strength of data if I am on wifi and not using the data connection? On my phone (note 4, rooted but stock) i pretty much always have full wifi signal strength, but i have have zero bars/no service on the signal strength icon and when that happens, if anyone tries calling me, it never comes through. I don't have anything in the missed call log - just no call. Can't send a txt either.
The next time the phone drops to zero bars/no service and i happen to have someone else with a non-sprint phone, i'll try calling myself just to confirm the behavior.
Same for me. The signal and data quality is ****e compare to Note 3

So on the same network you had better signal strength with a note 3 vs a note 4?
