What is "aggressive wifi/cell handover" in developer settings? - Galaxy S6 Edge Q&A, Help & Troubleshooting

How is that different from smart network switch? Could it be related to the problems people are having with wifi dropping when device is sleeping?

Could it be for t-mobile wifi calling and leaving a hotshot but maintaining the call

I don't have a t-mobile phone. I don't think this is related to VoLTE. Also I don't see what would be aggressive about it. My guess, and that's just a pure guess, is that it makes ur phone jump from wifi to lte or vice versa more quickly. So for example if it used to wait 10 seconds before giving up on a weak wifi signal, it would do so in 5 seconds.

Edge network?

On the vibrant theres an option to run on I think what is called edge network, I could be wrong, does verizon have such a network to run off of my buddies vibrant's batteries life is unreal...well aolt better than mine.???
Thx

Edge is the 2g network, when you drop a 3g signal your phone gets stuck on Verizon's version of it... I guess it would improve battery life but don't try to any browsing on it...

Edge is a type of GSM network, Verizon uses CDMA, so no, you can't use EDGE.
The equivalent to EDGE in Verizon would be the 1X data connection, as opposed to the 3G (EVDO) connection. I know we can disable mobile data with Froyo, but I don't think there's any way (without some kind of hack) to force the phone to always use a 1X data connection.

It's somewhere in the hidden menus.
GSM phones, in general, get much better battery life. It has to do with the network. Coverage vs Battery life it's a toss up

Fixing Signal Issues (3G/H Switching)

Hi
Does anyone know how to fix this issue? I am in a good area for signal and with previous phones am consistently on H. With my S2 it frequently switches between 3G and H even if it stays in the same spot. It will do it every few minutes.
This is causing havok when I try and tether and my Transformer and laptop keep getting signal interruptions.
Does anyone have a fix? I have Fast Dormancy disabled and I'm aware there may be some other engineer menus that have signal settings in that might work?
Thanks
Paul

Interesting.. And I thought it was just my network vodafone
Mine also switches between G/H/H+ all within 5 secs... yeah 5 seconds and it is kinda annoying.
Are you on GIFFGAFF as stated on you profile? or other network? cause I thought if might have do to something with vodafone..
Otherwise may be its something to do with the hardware settings, I too would like to know the answer
I've kept mine to use WCMA all the times...

Yes, I'm on giffgaff.
Glad its not just me. Maybe the antenna is a little too sensitive.
Anyone know the secret code to get to the GSM/UTMS bits?

OK. Found the 2263 code but that seems to want to enable/disable actual bands.
Am I looking into it too hard!?

Now, for me wouldn't 3G and H/H+ both be considered as WCDMA under Mobile Network Settings? G and E would be GSM right?
If that is the case, staying on WCDMA wouldn't fix the problem.
Sent from my Transformer TF101 using XDA Premium App
Your phone shouldn't lock onto a H/H+ signal unless it has started to download data. That's how the protocol works.
If your phone is sitting idle it should be on 3G.
You should only get H/H+ when your phone is actively downloading.

OK. So how can I stop it flicking between the H and 3G. For instance when I am trying to stream it will get interrupted, or if I'm wirelessly tethered?

i'm from tunisia and have the same pronlem here.
Please developers help us to get rid of this 3g/h issue.
Guys,
I got the same problem here i n Brazil using a VIVO carrier.
I set in CONFIG -> WIRELESS AND NETWORK -> MOBILE NETWORKS -> NETWORK MODE -> WCDMA ONLY
I don`t know why it worked but now its working fine.
Could you test?

No problems to report in Amsterdam.
I'm biking through the whole city to get to work, no disconnects using TuneIn or Google Music. Provider is Vodafone, HSDPA+ all along the way.
Its Android issue
Think when iPhone, Windows phones have not had this issue, wat else other than Android. I have tried 3 different handsets. 3 different network - 3, O2 and Vodaphone. All has same problem. Android is the only thing common. I have been scouring the internet and posted everwhere possible since Dec 2010 from when I became Android user. There is no solution. Everone seems busy making their own Android versions and apps. Result there is no basic data and voice stability on Android. Have been relying on my decade old treo to receive n make important calls. Wonder where this is going. My heart n soul seems to sway to the iPhone lately. Atleast wat they give works well.
Its Android issue
BTW those config settings are useless too. I have even used the code to get into hidden menu and change config but no use. It's the same issue. From H to 3g and from G to E I gsm.
Sorry for the question, but whats the problem with switching? I have the same thing but is not a problem for me.

Nobody should get worried about that switching, THIS IS NORMAL!
H/H+ is an high speed 3G protocol.
Basically:
1. 3G means DL 384 Kbps tops. The modem is under 3G signal most of the time. Whenever something on your phone starts checking/d-loading it communicates at THE BEGINNING under 3G protocol. Also, long ping time> 210 ms.
2. HSDPA max 14 Mbps/HSDPA+ can go as high as 42 Mbps ( topped only by cell tower). If there's need for large packet data or shorter ping time, IT AUTOMATICALLY SWITCHES TO H/H+(IF AVAIL). Hsdpa consumes more power and it's a communication protocol. When connected under H/H+ error correction bits are transmitted along data stream. It's like switching your home wifi on b/g/n. ...or like the automatic gearbox going to overdrive.
If you see a lot of this switching it means there's a lot of downloading/uploading going on.
I have it switching too between 3g and h on o2 and its making the internet so unstable you cannot do anything at all. This is certain not normal as the switch happens every second and continues to do so until phone is off
Mine is also switching to 3G once connection is idle for about 3 seconds. So far no problem and it uses less power than my SGS1 for browsing since my SGS1 doesn't switch to 3G when idle.
Mine is no problem between this signal switching, check your area or check your country maybe too much communication devices there so that's why it is distorted. Just use the common carrier with plenty of cell sites for a good signal of your phone.
What do i need to dial to fix it to 3g only from 2g?

Wifi causes network signal loss

As the title says, periodically wifi connections will cause my note to loose connection to the network. I will get the "no signal" crossed circle where the cell signal strength bar would be located....after that happens i have to restart my phone to reestablish the network connection. Wifi is not affected. No amount of toggling radio switches or going into airplane will affect the network loss...only a restart.
I am on the stock att Rom at the moment.
Anyone else experience this?
sent from that note in my pocket
Every time I've encountered quirks with WiFi and cell signal on my android phones airplane mode for 15 seconds or so has fixed it. Odd.
Hopefully someone else chimes in for you. Bump.

Anybody have a fix for this issue?
Seems everyday, I will have to turn on airplane mode to jump start my mobile network. I'll see a signal (3-4 bars) and 4G/4G LTE...expect the signal bars will be gray. I always have to activate airplane mode and then turn it off, to reconnect to the mobile network.
I've reflashed my custom GB ROM (Flapp's) and no luck. I still end up having to do this at least once a day. I don't know....
RIL / Modem conflict perhaps?

Roaming Issue

I am on 3 Ireland and i visit the UK quite often and the phone automatically defaults to 3 UK, but ive noticed when i return to Ireland only in certain places for example in work the R (for roaming) letter shows beside the signal bar in the statusbar and it wont connect to the Internet, when i go to settings > Mobile networks >Network Operators > select automatically it doesn't always reset it to what it should be whereas sometimes it does, this only appears to happen in certain places too and it's a bit annoying to be honest, pointless talking to 3 Customer service too they keep saying "you must be in a bad signal area" right since when was Dublin City Centre a bad signal area then.
Does anyone know why the phone is doing this, as i said it only appears to happen in a certain area, my SGSII never gave me this problem at all.
Bump..
anyone have any idea as to why phone behaves like this?
Mine shows the R when I don't have very strong 3 signal so it hands off to whichever network 3 have their network sharing agreement with.
Do you have the data while roaming box checked in mobile network settings?

No always have that unchecked as im not roaming and only use WiFi or my UK SIM card when im outside Ireland.
It's bizzare because it only happens in a certain place in the Dublin 3 area,i haven't seen it happen anywhere else, it's a bit annoying actually as i cant access the Internet then off of a sudden the R goes away and im back to normal.

Well check that box because even though you are in Ireland it is still considered roaming because you aren't using 3's network when the R is there.
I'm given two choices on my galaxy nexus, national roaming and international roaming, but on my S3 its all lumped into one checkbox.
You'll need to have it checked to get Internet connectivity when the R comes up.

Vodafones network is bigger so they don't need to share.
3 share network towers with someone (02 I think) to help boost their national coverage percentage.
You can't get 3g data while the R is there, only 2g.
But Vodafone don't have unlimited data and where I live 3 hspa+ is faster so there's the trade off.

Roaming not working at all
I got to both UK and Germany and I got a strange behavior: I was connected to a network with full bars but notification bar was showing "emergency call only". No way to both call, text or receive.
It worked intermittently for the 10% of time only.
No luck switching to 2G only, selecting an operator manually or rebooting the device.
I'm on AFL6 fw, but it did not work on previous two releases as well.
My home carrier is 3 Italy.
When I got back home I had exactly the same issue when moving out from flight mode, a reboot solved it tough.
Sweden 3 and gets connectivity lost due to roaming every time I fire up wifi

WIFI

my wifi on my note 2 keeps switching from 4g lte to wifi every minute or two. Even if its on idle nor in use, it switches
Sent from my SAMSUNG-SGH-I317 using Tapatalk 2
The phone grabs the best available signal, but if the signals are equal strength it goes to wifi.
You can turn off wifi or cellular, depending on which one you want.
When inturn of data and start usung the phone wifi just turns off and on

Perhaps the users in the note 2 forums will have the answers you need, as they share the same device.
Our note1 devices do not have this problem.
I suggest you check the note2 areas for your answer....g
