are the signal bars actually accurately reflect the signals strength? reason why i am asking is because i literally get 0 bars at home, yet data works and i can still surf the web and watch videos.

those bars are not indication of strength (not all the time)
this is a very iffy conversation some will say yes some will say no. me personally when i have 1 or 0 bars i have a bad connection with data/voice. when i have max bars there is no issue whatsoever. but you need to look at the dBm meter that is more accurate. and just self observation of itself it may vary in the place you are too. in my house with 1 bar on LTE I get 20Mb/s Down 5Mb/s Up. And at work I have 3 Bars and only reach 10Mb/s Down and 2MB/s Up. however my voice coverage wherever I been has been spot on.
I have one bar at home, just did the speed test: 16Mb down, 6Mb up. If you dial *#0011# you'll see your RSRP exactly (reference signal receiving power), mine shows about -105.
If calibration was done properly it should be something like this:
0 bar - 0- 20%
1 bar 20-40
2 bar 40-60
3 bar 60-80
4 bar 80-100%
So even at 0 bars you could have OK reception.
But there is more to it, you can have strong signal, but also strong interference and a lot of other users could jam up otherwise strong connection.
To be honest I'd much rather have zero bars and still connecting, than phone lying to me that I have good signal and not able to connect.
I have one bar at home also, which is about -110db for me. Speed test shows 5 down and 2.4 up then went into network communications issues.

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.
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!
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?

Hello,
I have a problem for a couple of weeks with my zenfone2 relative intensity of cell phone signal.
My operator is TIM Italy.
Often the signal, while I'm outside, goes to 1 or 2 bar and even to 0, giving me problems as I speak on the phone.
The network data only it works when it is in 4G/H when it should switch to 3G or Edge does not go for the 99% of the time and often have internet disabled or zero signal bar.
Sometimes, when, for example, I'm in a tunnel with car and the signal goes to zero, I can not more to hang on to the network having 0 bar signal and I have to reboot it 1-2-3 times.
I reset the phone to its original state but I do not think much has changed.
At this time, in my office I view 0 notches, rarely see 2 "connectionless data to the Internet."
The firmware version I have is: LRX21V.WW-ASUS_Z008-2.20.40.88.
Thanks for help because this is very much frustrating.
Try set cell data to 3G/2G only. Maybe 4G signal is not strong for you. I have almost the same problem but everything is working when I set it to 3G/2G only and not 4G
