Switch network mode to 2G/3G/4G/(5G)/WIFI

[stefanprivat]

@anuraag

Sorry, I only mistyped here during post. In flow it is value 9 and note value 3.

But I will take once your flow and test with that.
I will also enable "I have verified the setting I know what I'm doing".

I will come back with results.

Best regards and thanks a lot!

@anuraag

Please find below my tests with your flow:

Initial staus before flow executed: Manually set in menu network mode from phone: 2G

Executed your flow, selected 4G (see below printscreen)
But as you can see in the upper status bar, is still "G" (2G) visible. Also in menu network mode from phone: 2G (wait for a long time)

see pic1

After that:
Executed your flow, selected 3G (see below printscreen)
But as you can see in the upper status bar, is still "G" (2G). Also in menu network mode from phone: 2G (wait for a long time)
But interesting is, that "old_setting" has value 9!

see pic2


After that:
Set manually in menu from phone network mode 4G:

see pic3

After that:
Executed your flow, selected 3G (see below printscreen)
But as you can see in the upper status bar, is still "4G" (2G). Also in menu network mode from phone: 4G (wait for a long time)

see pic4

Attention to the pic order: 3, 2, 1, 4!!!

Now alos the 4th pic

So is it working or not? Does it properly changed your network mode from 4G/3G/2G to 3G?

You have to wait some seconds for your device to switch network.

"4G"(2G)

When it shows 4G only (not 4G+) then your device is working on a 4G network not 2G.

Does your network actually works on 3G?

[stefanprivat]

Unfortunately no, it is not working.
The captured Debug Dialog shows always correct values, but phone never switched in the requested state.
Does your network actually works on 3G? >> No, phone is still in 4G after last flow execution.

[anuraag]

Try
1) manually switch to 2G mode.
2) execute my flow. Select 4G/3G/2G mode, wait some seconds and check whether 4G icon is showing or not.

Does your network actually works on 3G?

i mean does your operator support 3G network?

@anuraag

Done, exact like your instruction.

As you can see in attached dialog output, I switched with your flow from 2G (old_setting 1) to 4G/3G/2G (setting 9).
But as you also can see, over 6 minutes later, the phone is still on 2G (also in menu network mode the same visible: 2G).
Fact: Phone never change the network mode with executing the flow.

(Yes, my provider supports all:2G/3G/4G/)

[anuraag]

Changing system setting isn't enough for non root device. We have to open network setting page ince after applying secure setting.

Try
1) manually switch to 2G mode.
2) execute my flow. Select 4G/3G/2G mode, wait some seconds and check whether 4G icon is showing or not.
3) open system setting page from where you change network mode. Don't change anything. Now look at Statusbar.

[stefanprivat]

1) Done
2) Done, wait 1 min. >> still only icon "G" for 2G visible
3) Manually navigated in phones menu to "Mobile-Netzwerke" >> "Netzmodus", where I can do the manual change from the mode >> status bar shows still "G" for 2G.

@stefan : It seems you have found the key value. And from your previous post, it seems your phone doesn't honor the changes made. If that so, it seems your only choice is using Control UI. To back from the previous setting, use back() or home() to go directly to home screen.

I have shared the flow to log the secure setting, including detail information how to use it and the setup : viewtopic.php?f=3&t=7931

@Desmanto

Thank you for the helpful information. I will consult them!
I will check also on the Galaxy S8, otherwise I know now, how to do the network change over the UI.

Thanks a lot to all here which helped in this case!

Best regards Stefan
