What is the WiFi Scan Process name? - Galaxy Note 4 Q&A, Help & Troubleshooting

Quick question/help. My phone wifi can not seem to be able to detect any new wifi network at all. But my already known networks from when I set up this phone in the beginning still work as long as I m at home. So I came to the conclusion that I have turned some kind of process off that have caused this problem. I use TiBu, Amplify Battery extender.
When I use other Wi-Fi apps, Wifi Fixer. I'm able to see other networks that are normally there.
So I m just wondering what is the process that takes care of this wifi scan, or this thing that allows the phone to show what it detected.

Android -> Auto manage Wifi vs. carrier network?

I was reading an article about how the iPhone will automatically connect to WiFi instead of using the carrier network, when WiFi is available. As well, it manages the WiFi on the phone in a manner which minimizes battery usage.
Anyone know if any of the Android Phones do this?
Related to that, even if it doesn't automatically do that: If we are in a free WiFi spot that we know about and turn on WiFi, will the Android phone use the WiFi as prioritiy over the carrier network, thereby negating need to turn off access to the carrier network?

If you have 3g open, and you enter a wifi area, there are apps you can download which will immediately connect to that wifi spot without you opening Wifi, but those apps drain the battery and will connect at any wifi that you have previously used, thus becoming annoying. I tried it last year on my Android device.
It is much better to simply activate wifi alone, then it will connect to that free wifi spot alone IF you have previously connected to it.
I'll give two examples: At home when I connect my Android device to my wireless router for the first time, it will ask me for password. Then it saves it, so that if I close wifi, it will open 3g alone, but then if I re-open WIFI on my device, it will connect automatically as it saves the password of all wifi spots you have, and it shows you also the list of all saved spots.
The same thing goes for open free wifi spots, first time you connect to it normally without a password, second time it will re-connect alone as long as you have Wifi opened on your Android Device. I wouldn't have my cell to connect to any wifi alone without me opening wifi as it drains battery a lot.
As soon as you open Wifi, and there's an open wifi place or a private one (provided you have entered the password before), your cell will automatically connect to it and will no longer use carrier network until you shut off WIFI.
Thanks for the detailed reply. Much appreciated.
Actually, pretty much what I expected to hear.

Stop auto-connecting to open wifi networks

I have a Nexus 4. I'm currently on 4.3. My phone auto-connects to every single open wifi network I walk past. Starbucks, McDonalds, Nordstroms, etc... every single one. I've tried both setting and not setting the "Notify me of open networks" option in the Wifi settings. No difference. Well there is, one setting just causes it to silently connect. I have NOT connected to these networks before. At the end of the day I have like 15 AP's queued up in my list that I have to delete.
This might be the most pants-on-head retarded design I have ever seen in a phone. I have only a few productivity apps on my phones. None of them meddle with wifi settings as far as I can tell. So, can anyone help me? Please don't offer me the advice of turning wifi off. I understand that is the kill-all for this, but it's akin to suggesting that longer battery life can be had by turning the phone off between charges. There has to be some option I am missing that is a never-connect-to-open option. I bounce between client offices all day and I need wifi to work smoothly.
Yup, same here. I've disabled the setting to notify me when an open notification is available, and it just connects to all and sundry, often causing me to lose connection with a server. Anybody aware of a fix for this? Do I need to root my Nexus 4 first?
WiFi 'scan/connects' with other networks.

Set your WiFi to be active on your network only, uncheck open networks, and select manage networks to a single AP, yours.
I manage a single connection on my Droid X, and 'forget' all other networks, and do not store any network data from these either.
This is the only way I am certain my phone will not look for other networks, but then again, you can turn off 'Update over WiFi only' as well.
Deselect anything that will cause the phone to look for a WiFi AP, but also remember that once done, your apps such as Email and FB may still attempt to update via the phone's network and not WiFi.

[Q] cannot auto connect to open wifi even though it is saved

my galaxy s4, running 4.2.2. There are two saved wifi networks, one is open, and the other is wpa security. The wifi switch of my phone is ON. Here is the strange things, when I came in to the range of wpa security wifi, my phone auto connect to the wifi network, everything is ok. When I came in to the open wifi networks area, my phone does not connect to the open wifi, even though it is saved, but I can mannual connect to the wifi.
So, why ? and how can I let my phone connect the saved open wifi auto?

Had a similar problem.
In advanced there is an option, cant remember it now, been too long since I looked at it, (a week :silly.
Something about switching to mobile networks if you lose your wifi. Make sure that is turned on, else the device decides a wifi connection is 'bad' instead of just out of range and won't remember it.

Thanks for your reply. I searched the menu which you mentioned, try every option that can select or unselect, unfortunately it won't work.
My device can connect an secure wifi auto when the signal is fair, but can not connect to an open wifi, only work by manual pick it.

[Q] Nexus 4 with AOKP won't connect to Wifi, "WPS failed" error

My Nexus 4 isn't connecting to wifi. More specifically, if I am connected to a remembered network, my phone does not automatically reconnect when I leave the range then come back into it.
Now, there are 2 wifi networks in the apartment and I've tried both. I actually just "forgot network" on the last remembered network on my phone because I was trying to connect to the better one.
Since I've done that, I am unable to connect to wifi at all, because the only way for me to connect to wifi before was to restart my phone and have it automatically connect to the remembered network.
Now that I don't have a remembered network, I cannot connect to anything, and my Wifi page on my phone will not show any wifi networks available and it won't even give the option to turn on wifi or to refresh the list. I have to reboot my phone, making sure the wifi is off first (using the toggle on the dropdown notification menu), then I can at least refresh the empty list. When I refresh the list, it gives me an error, "WPA failed. Retry in a few minutes."
I need this fixed. I live in a basement apartment and my cell signal is usually unavailable while I'm home.
I was running the AOKP 4.3 milestone when I started having the problem, then went back to stock, put on a 4.4 nightly ROM, had the same problem, then went back to the same 4.3 milestone. Unfortunately, I didn't leave my phone on stock 4.4 long enough to see if the problem persisted there.
Is there anything I can do at this point before going through the process of bringing my phone back to stock again?
Thanks
Update: After restarting my phone some 20 or more times, I was eventually able to see the list of networks and put the password in for the new network. So I at least have wifi now because my phone automatically connects.
However, all the problems stated above are still the same. I lose connection and cannot automatically reconnect when I go out and back into range of the signal, and can only regain the connection when I restart my phone and it automatically connects to the one known network on reboot.
If there's any information or anyway to try to fix it, I'd love to know.
Thanks

[Q] Wifi continuously scanning while phone has good wifi connection.

This started Feb 3rd or 4th. The phone will connect to the wifi network, with a good signal. It will then re-scan every 5 seconds or so. This is causing all sorts of data transfer issues from downloads freezing to apps losing connectivity while running.
I am running on Verizon.
Specs below: (Sorry can't direct link yet...need 10 posts)

I am now running Android 5.0 but had NOT updated to 5.0 when this problem started.
I scoured google a bit and found an ATT forum that is essentially reporting what I am.
forums.att.com/t5/Samsung-Discussion-Support/Samsung-Galaxy-S5-Wi-Fi-Connectivity-Problems-After-4-4-4-Update/td-p/4190704
All other devices on the network are operating without issue - phones and computers - as was mine until now.
I have power cycled everything.
I have checked the routers settings.
The phone has been power cycled several times.
The phone has had every wifi setting that would be causing this scanning, that I know, disabled.
The following are off in Wifi > Advanced:
Wifi notifications
Passpoint
Always allow scanning
Smart network switch
I then, after the above, updated to Android 5.0. The issue still persists. Help me please.
My device does this, too. Cant say I have ever really noticed, I dont know if it has always done this or not.
I am not experiencing any issues like you describe.
Now that I think about it, I think it will always scan at a set interval when you enter the Wifi settings. It assumes you are looking for a network to connect to. I doubt its scanning when you are not in that setting.
I had this problem the other day. I went to wifi settings and had it forget the network and then rebooted and reconnected to my wifi network and it seems to have resolved the issue. others have just switched airplane mode on and off and this fixed it. good luck
