[Q] Programmatically searching and choosing a network provider - Android Q&A, Help & Troubleshooting

Hi,
I'm currently developping an application that resets your connection when your signal strength is too low.
I'm trying to do this by searching and choosing your network operator (settings-> wireless and networks -> Mobile networks -> Network operators).
I noticed this way has a few advantages over switching to airplane mode:
- Wifi and/or bluetooth doesn't get disabled
- You don't 'loose' your reception and this can still make calls (tested this; you will still lose your data/internet connection, however)
I'm trying to find some way to automate this when your signal drops too low.
Does anyone know how to do this (preferably without root, but if needed, that's fine as well; Busybox shell commands are fine too)?
Thanks

good one! waiting for that app!

[Q] Timed switching between 2G/3G

Hi,
I have terrible 3G (UMTS) reception at my office, but good 2G (GSM), so to save battery and make the phone as usable as possible I switch to 2G when at work. I used to go to Settings -> Wireless & Networks -> Mobile Networks and switch on "Use only 2G networks", and lately I've been using the "Toggle 2G/3G" function in the CM7 notification power widget.
However, it is slightly annoying to have to remember this toggle every time I enter/leave the office, so I'd really like to have an app that does this for me. Does anyone know of an app that can toggle 2G/3G based on either location or time? I'm using CyanogenMod 7.0.3 if that makes a difference.
I've tried a few different profile/setting switching apps, but none of them seem to be able to do this (while all can turn APN on/off, which I don't want. I want data enabled all the time, just over GSM part of the time). Even the apps that claim to have a toggle for 2G/3G seem to be just shortcuts to "Mobile Networks" settings.
Would really appreciate any helpful suggestions
You might consider buying Tasker. It can do what you wish even on a geolocation basis. So whenever you enter/leavr certain location proximity it will do whatever you set it to do.
Thanks, tasker does just what I wanted.

[Q] Looking for a wireless management app

I'm looking for a smart wireless management app for my Streak.
Main function I'm looking for is the ability to let it automatically switch between WiFi and 3G as soon as signal drops below an exact specified value.
Right now I have a fairly fast 3G connection on Vodafone NL, but when I'm home I switch to Wifi to save cost. At some spots in my house the 3G connection is way faster then my Wifi signal, so I want it to atomatically choose the fastest connection.
Is there any simple app out there that chooses the connection with best send/receive qualitiy?Anyone knows about an app that can do this?

There isn't one that chooses, your phone does that already, but there is this widget
And/or this

[Q] Alcatel One Touch Evo 7

Hello,
I'm new to this forum. I have Alcatel One Touch Evo 7 tablet and after updating the software to newer version, it started having problems with the 3g modem - it can detect a network but it won't connect with any. Surrpisingly - whenever I connect with WIFI, the 3G or EDGE icon appears as well and it looks like I was connected to both WiFi and mobile network! I double checked the APN settings and it was working before - now it isn't... Is there some way to downgrade the software or flash it? I don't have a warranty for this tablet.
When you have active wireless connection, the "modem icon" only show signal strength, it's true that E or H depend on "what it hear" but that's all. So if modem get signal from umts it will show umts (even when he is unable to connect because of poor quality), because he thinks that he is connected to the GSM, but he is connected to net threw wireless. (like it have only one connection status for wireless and gsm)
And as for me, my evo7 behave the same way as yours when i have something wrong with APN, so my guess it that you have:
-apn or other settings problem
-signal strength - check your signal and other in settings
-hardware problem - maybe some interference with other components, like gps, wifi, ... (i have evo7 that have good gps but very poor gsm, and my friend bought evo7 that have GSM like a rock, hardly ever lose gsm network, but gps work like hell, sometimes never get fix or lose it all the time)
My question: How did you do software update? I somehow didn't find any room or how to do that.

[Q] Wifi switching to mobile data (and back)

Hi everybody,
I'm facing an annoying problem: when my phone "considers" the wifi signal "too weak", it automatically switches to mobile data (even if the latter are disabled), the result is the mobile frequently drops the wifi connection in some places at home where the signal is a little less intense.
In my phone, options in the advanced settings of the Wi-Fi do not let me choose anything about automatic switching from wifi to mobile data (or such options aren't displayed)...
What can I do?
Is there a way to access "hidden" settings like the ones mentioned?
Thanks for your answers!

Can I get my device to auto-connect to WiFi without internet?

Hi everyone,
I own a Nexus 5 and I am running stock firmware, Android 6.0 MRA58K, unrooted and bootloader locked. I use this device at work and frequently connect to a WiFi LAN that has no internet connection (by design -- I use it to talk to other devices on the network). In older software versions (I believe back in the KitKat days if I recall), I could simply turn on the WiFi slider on my phone, and it would automatically connect to the network, and I could immediately start talking to the devices I need to (this was excellent!). Then when Lollipop first rolled around, it would still connect to the network automatically, but it would realize that there's no internet connection, so it would then prioritize the Cellular Data network, preventing me from communicating with my network devices. So I had to do an extra step by disabling my data connection, then things would work properly again. (Of course, this also meant that when I wanted to jump off the Wi-Fi, I would need to re-enable Cellular Data.)
Nowadays, Android seems to remember that my WiFi network doesn't have an internet connection, so it never joins it by default (very frustrating!). So every time I want to jump on the network, I need to turn on WiFi, then manually select the network to join, then go into the Data section and disable cellular Data, and then things would be working fine. Of course, if I ever walked away from the Wi-Fi range and then came back, I would again need to manually select the network.
And now with this lastest Marshmallow update, a new Notification pops up every time I join the Network that says:
"Wi-Fi has no Internet Access. Touch for options." When touched it says, "This network has no Internet access. Stay connected? Yes/No" There's also a checkbox that says, "Don't ask again for this network". Every time I check that box, and say YES to stay connected. And yet each and every time I connect to the network, this notification appears again! (The checkbox seems to do nothing). I've looked at the Advanced options in the Wi-Fi settings, and nothing there seems to help.
So my question is, is there a way for me to go back to the "good 'ole days", where I can get my phone to automatically join this WiFi network, and still prioritize it over cellular data?
If need be, I'm perfectly fine with rooting/unlocking my phone, if I need to install some custom firmware or whatever.
Thanks in advance for any suggestions you might have!
-Tom
