[Q] Automatically turn on WiFi when 3g unavailable? - Android Q&A, Help & Troubleshooting

Hi, I was wondering if there's an app/service that turns wifi on automatically when my mobile network is not giving me a strong data connection (at least 3g). and of course turn it back off when mobile network is available again.
I want to do this because I have an unlimited data plan, and this will save battery and give me a more secure (private) connection.
Anyone knows of such app/service?
Thanks

turn off data while on wifi to save battery?

While on wifi, do I need to turn off Data in order to save battery? I *think* the phone will use the wifi if its available anyway instead of cellular Data but will actually turning off Data while wifi is enabled and connected save battery?
The data is automatically turned off while wi-fi is connected unless you have some rogue app that insists to use cell data connection.

Note, this is only if "wifi sleep policy" is "never".
Otherwise, it'll go to the cell connection when the screen is off.
The only app I know of right now that can force cell data traffic while wifi is connected is the Market when it does its initial compatibility checks. (Downloads still go over wifi.)

[Q] Is there a way to access internet on my phone while tethering?

I have currently gone over my broadband limit with my ISP, so I am using wifi tethering on my SGS3 to access the internet as I have a truly unlimited data plan. However I noticed that I cannot use the internet connection on my phone while I am tethering, I have always been able to do this with previous phones, is there a way it can be done with SGS3?
It does work for me and there is no reason why it shouldn't.
Are sure sure your data network is not just overloaded or flaky?
Well it's not a network restriction because I used the exact same sim in my DHD yesterday to tether and I could access the connection on my phone too
works for me too.

[Q] Simultaneous WiFi and 4G

I have a few cameras that create their own WiFi hotspots (GoPro and Eye-fi) to establish a connection with my phone. When I connect to their WiFi, I can get photos, but I lose my internet. I'm sure I can figure out how to use the phones WiFi hotspot feature, but that has always made my phones heat up and quickly die. I'm wondering if there is a way to connect to a non-internet hotspot (camera) and my Verizon data connection at the same time.

mobile data is disabled but data plan is charged on CM12.1

I have a LTE-enabled SIM on a C6843. My typical scenario is: phone is on airplane mode during the night, and goes out of airplane mode in the morning. Mobile data is always disabled.
Recently I noticed that my operator has been charging my pre-paid plan with data connection charges although I have data connection always disabled. I get daily charges for data connection with 0,000 MB transfered (TIM Brazil, if that matters).
The phone is on CM12.1 20150917, but this has been happening for at least 30 days (based on the data charges).
Has anyone seen similar behavior? Is there some workaround?

workaround
Changing data mobile connection from LTE to 3G seems to mostly avoid this issue for me. It does add the extra step to change connection to LTE when I do have to use the mobile network.

Connectivity issues while on non-internet serving WiFi

Galaxy S10+, latest Android update from my carrier.
While hooked to any Wi-Fi that doesn't serve internet (my camper accessories, for example, are controlled by the wifi, but serves no internet connection), it allows very little data to function until I shut the wifi back off or end the connection to the camper.
I have my settings set up to keep mobile data active and also have aggressive wifi/mobile data handoff enabled.
Does anyone have a fix or any suggestions? It's really frustrating as I a few other devices that require a wifi connection to control but don't serve internet access.
Thanks in advance!
