Apps that require connectivity defaulting to dial-up

The issue I have is that I live in an area with minimal mobile coverage so have to rely on wi-fi connection when at home. Just today my HD2 has started acting up with an issue that I have experienced previously. When I try to update weather, stocks and other apps that require connectivity I get the error message about the dial-up modem being disconnected - the cause is fine as I have no signal but I don't understand why these apps are not swapping to the wi-fi connection. Browsing the internet is fine as is the YouTube app but all others (including email) are failing as they are trying to dial-up.
I have done some experimenting with mixed results:
1) If the phone radio is off (aerial followed by an x) - then the phone will fallback to wi-fi and applications that require connectivity seem to work.
2) If the phone radio is on and it is trying to find a signal (aerial with 3 dots cycling) then it will not issue the dial-up disconnected error - instead it will try to connect but then either time out (for apps like Omarket and Sky Mobile) or will work with mixed results (stocks and weather - although it only updates locations other than my location).
3) If the phone radio is on but there is no signal (aerial followed by exclamation mark) - then I get the dial-up disconnected error on apps that require connectivity (with the exception of Opera and YouTube).
Does anyone have any thoughts on what causes these inconsistencies and if there is a way to resolve them? When I had this issue before I did a hard reset which seemed to do the trick although with hindsight I am not entirely convinced whether it made any difference - especially if Apple's excuse for their iphone4 signal issue is to be believed (i.e. at times I could have a signal even though the phone is indicating that I do not have one).
I presume in the real world i.e. one where one has decent mobile coverage - this issue is unlikely to occur or certainly less obvious to spot

Hey,
If you set up your dial-up connection as part of your WiFi connection ( ISP or Work) and then set "programs that automatically connect to the internet" to the WiFi connection the automatic program will no longer try and connect if you are connected by WiFi.
go to settings-menu-all settings-connections-connections and add a new modem connection to your Work network. You need to get the settings from your service provider or copy them from the existing data connection.
once done, got to advanced and select networks and choose the work connection for programs that automatically connect.
that should help

So in short I would have a single config that contains both the wifi and mobile settings as opposed to the two separate configs that I have at present. I will give that a crack and see what happens.
Thanks

2 issues in 4.3

I'm running the official BTU 4.3 release on my I9505
I've noticed two issues with 4.3
a) Wifi
From time to time, perhaps daily, my phone loses connection to my home wifi. I get a notification which says something about being disconnected -- don't remember the full text. When I click on it I get taken to the list of wifi networks and underneath my local wifi network it will say "Sign-in is required".
It may be working as designed - checking my newish BT HomeHub 5 I can see the PPP session recycled twice overnight. Oddly this was initiated by upstream admin according to the logs, not a vdsl failure.... since the hub will intercept pages when ppp is down it's possible this caused the confusion
b) Security policy
I sometimes see a notification that an app required access to system, but didn't have permission - yet when I click on the notification I get taken to a full list of apps -- how do I find out which one was trying to be naughty?

The WiFi problem can be quite annoying.
I think this is not an improvement over the previous functionality.
The idea seems to be that as soon you have to manually log in to a WiFi network Android switches to the cellular connection to make sure you are always connected.
The thing is that at my work place this means every time I get somewhat out of range of WiFi (elevator, toilet, staircase) and walk into range my WiFi stays disconnected until I remember to reconnect it.
I only have to actually sign in once a day, but as Android thinks it is a network you have to sign in to it will not automatically reconnect to that network.
Meanwhile the phone is using up my data allowance....

[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.

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

3G/4G Connection unstable: mobile data active but internet goes down randomly

Hello guys,
I've had my OP5 for 2 weeks now, quite happy with it so far but I have a major issue with my 3G/4G connection which is very unstable.
When I am connected to Wifi network, everything is fast & smooth but as soon as I switch to 4G/3G, the data is very unstable: sometimes, the internet connection goes down for few seconds or minutes.
I can see the connection is active (3G/4G icon, no exclamation mark), the signal is good (more than 70% in most cases) but the data meter in my status bar shows abnormal transfer rates (below 2Kb/s). After several seconds/minutes of patience, the connection goes back to normal with very good (normal) transfer rates. It can work very well for several minutes (downloaded some HD movies within few minutes without interruption), then goes down randomly.
I already checked the SIM cards, network & APN configuration and everything is correct. I tried on a couple of SIM cards, on both SIM slots and the problem remains the same, whatever SIM card or slot I am using. The SIM card were tested in my "former" smartphone and work perfectly and in areas where the network and signal are stable and do not lose connectivity with my former smartphones, it only happens on the OP5.
I tested on several apps that require internet and the result is always the same: either the app says there is no internet connection, or it takes forever to load... This is not specific to an application.
My phone is rooted with Magisk 13.3, with the original OOS 4.5.8 ROM. I am using Netguard and AppsOps to control the apps accessing internet but I don't think this is the source of the problem because the Wifi works well and apps still access internet through 4G when the connection is up.
Any idea?
Thanks for your help

Best way to connect non SIM head unit to internet?

Trying to get internet access on my head unit without paying for a hotspot. I'm aware of PDANet and have used it, but it's sometimes unreliable to get a connection at first and requires restarting it several times. I'm looking for a more automatic solution that will connect as soon as I start the car. Any advice?

I bought a Huawei E8372 LTE stick. It provides both a WiFi access point and a USB ethernet interface that works with my Eonon GA9498B, so I basically disabled the WiFi entirely for the time being. Setting up the stick can easily be done by inserting the SIM card, plugging it into your computer, navigating with your browser to the IP address mentioned in the manual; it's advisable to deactivate the SIM PIN so the stick can just boot and establish the mobile connection without having to enter the PIN every time you turn off and on your car. Boot time for the stick is 20-30s max, so the connection is basically already available as soon as the radio's main screen appears.
Just watch out: I haven't yet found a possibility to mark the ethernet connection as metered in Android, so apps which have different data transfer behavior depending on whether you're on a WiFi or a mobile connection will go on full data blast mode if you don't tell them not to. Take Spotify, for example: If you have marked songs for download, the app will synchronize all changes right away via the LTE connection, even if you've configured Spotify to only do that on WiFi connections. So what I do is putting Spotify in offline mode by default, and only change that when I'm at home and the radio is connected to my WiFi (which luckily takes precedence over the USB-ethernet connection). Same goes for my HERE WeGo offline maps: I configured it to download them manually, so it only checks for map updates and notifies me, and I can download them when I'm home. Google Maps is pretty spare about its data usage anyway, so no need to change anything here. I also disabled automatic updates in Play Store, so it just notifies me of available updates which I can then install when I'm back home.
This COULD be avoided by activating the stick's WiFi hotspot, connecting the radio via WiFi and then, in Android's data usage settings, mark the WiFi network as metered. I tried that once, and it wasn't all too reliable - Android keeps forgetting these settings irregularly (the WiFi is shown as metered in Android's settings after I changed that setting; will stay like that for a while whenever I take a look again; and at some indeterminate point will show "Automatic" again, which means it's being treated like your cable router in your living room again) and doesn't tell you so at all, so apps might first behave correctly (i.e. like they're using mobile network), and later recognize their environment as being in an unlimited WiFi network and download everything they do in the background, eating up your mobile data. Thus I rather control each app's settings in this regard manually.
