Radio Switcher for Jolla (2G-3G-4G)
 

I changed my mind. I wrote earlier that I won't update 3G/4G radio switcher to include 2G option as such mode is available in mobile network settings. However I got an idea to create application running in cover UI only and radio switcher felt like feasible application to try it.

Here we are with totally renewed Radio Switcher 0.2 running with cover UI only. You can toggle between 2G (gsm), 3G (umts with fallback to gsm) and 4G (lte only) on multitasking screen.

Radio Switcher installation package is available from OpenRepos and with Warehouse repository client.

Application can be quit either by clicking it twice or by using system gestures with hold and press until application can be closed from (X).

Available versions:

• 0.1 with two application icons 3G and 4G, with no application window
• 0.2.1 with single renewed application icon and cover UI for switching cellular radio technology

I will keep both versions available until Jolla will publish official 4G/LTE support, so you can choose which UI you prefer to use.

Radio Switcher does not have any own local or remote data storage, but instead it changes system configurations. No application logging or remote statistics logging or other communication either.

Changes:

Version 0.2.1 updated to fix signal strength calculation and add operator and active network technology to cover view.

Do you have sources hosted somewhere? I would prefer tweaking it so that the fallback to incoming calls would work in LTE :)

You guys make me learn new things every day. Wasn't, but now source code is available in:

This is very nice. Anyone try this in Canada. Unless I'm mistaken one of the LTE bands for Jolla (2600Mhz Band 5) should work in some parts of Canada (BELL).

Re: Radio Switcher for Jolla (2G-3G-4G)
 

Wow effect was real good. Tried myself. After several rounds of frequency switching 2G and 4G worked well, but at 3G phone did not make network connection. In settings my mobile network connection was disabled and I was not able to enable it. So I finally resorted to reboot. That sorted it out.

Re: Radio Switcher for Jolla (2G-3G-4G)
 

4G only can use for connected power supply? seem I can use 4G without connected power supply

Re: Radio Switcher for Jolla (2G-3G-4G)
 

It works also without, so must be just the network area that you are in.

Re: Radio Switcher for Jolla (2G-3G-4G)
 

I think TMavica had Warehouse description in mind that warns about very high power consumption on 4G and suggests power supply. From experience is not that bad at all

Re: Radio Switcher for Jolla (2G-3G-4G)
 

I have tried this twice without power supply, and it did not eat my brain nor battery too much. I have not used 4G for more than 10 minutes at a time, and I have not noticed significant drop of the battery level during my try outs.

Location matters, if the reception is poor, equipment usually use more power.

Re: Radio Switcher for Jolla (2G-3G-4G)
 

Am I missing something here now...??

AFAIK there's no 4G (LTE, that is) available in the Jolla device, at least not in SailfishOS ver. 1.0.3.8 which I am running.
So have you got a newer update lately?

Re: Radio Switcher for Jolla (2G-3G-4G)
 

No official LTE, but you can turn it on with the app from this thread (no call/sms during lte though for now)

Re: Radio Switcher for Jolla (2G-3G-4G)
 

Ah, cool! Maybe I'll have a go at it.
First I need to find out if my subscription covers LTE, as I believe it might be just 2G/3G.

Re: Radio Switcher for Jolla (2G-3G-4G)
 

Thanks - getting some great speeds with 4G.

When i use the app and switch it to 4g, it just keeps saying offline and searching....

When I switch back to 3g I can't turn my internet on, it won't allow me to in settings (even though the internet was on when i switched from 4g to 3g) - requires a reboot

Re: Radio Switcher for Jolla (2G-3G-4G)
 

mattaustin: That's superb!

Dared: settings application is famous in not responding. It can do it when you just leave it open. Offline does not mean your internet connection is switched off in settings, but that modem is not connected. If it stays offline and searching it means that either there is no LTE network coverage on supported bands or that your mobile subscription does not have LTE service enabled. That situation you described can be in most of the cases solved by switching to 2G/3G and waiting for a moment, some times even minutes until modem can access operator network. Sometimes you need to switch multiple times between 2G and 3G. Notice that icon means only selected mode, actual is beside Network heading (GSM = 2G, UMTS = 3G, LTE = 4G) I have had similar issues few times but it has never required reboot. With my operator every switching directly from 2G to 4G and "punisment" is that I have to wait few minutes to access any band.

Re: Radio Switcher for Jolla (2G-3G-4G)
 

I did get once into endless searching state, but instead of rebooting airplane mode on/off did the trick for me

Re: Radio Switcher for Jolla (2G-3G-4G)
 

Okay, so i'm on the same operator as matt austin is (Virgin Mobile). I've checked their coverage map and 4G is available in my whole suburb.

I have activated 4G with Virgin. That's definite

When i switch to 4G there is no network whatsoever. That means there's no 4G symbol displayed, nor an internet status on my home screen. I can't connect to the internet, nor can i even select in settings to connect to the internet

Strange :/

Re: Radio Switcher for Jolla (2G-3G-4G)
 

Virgin / Optus are having major problems today, I have no internet connectivity on 2/3/4g.

Re: Radio Switcher for Jolla (2G-3G-4G)
 

Just checked - apparently no issues in my area

I'll double check everything with my account and give it another go tomorrow

Re: Radio Switcher for Jolla (2G-3G-4G)
 

I had a crash yesterday when switching from 4G to 2G, the phone switched off.

Re: Radio Switcher for Jolla (2G-3G-4G)
 

While 'old' version works, 'new' versions seems to be doing nothing here, but presenting a coverpage - clicking it doesnt change a thingy, double-click exists the coverpage :)

Re: Radio Switcher for Jolla (2G-3G-4G)
 

swipe on the cover to switch, after clicking the available action turns to exit

Re: Radio Switcher for Jolla (2G-3G-4G)
 

nieldk: there is newer version available. Switching works in both versions by swiping. In older version you have exit works with double tap, newer with tap and swipe as szopin wrote.

Re: Radio Switcher for Jolla (2G-3G-4G)
 

Does this has the "loop problem" effect that Jolla staff has been told not to use?

Edit: Will wait until the 'fall back to 3G' function is available :)

Re: Radio Switcher for Jolla (2G-3G-4G)
 

I do not know what "loop problem" you are writing about.

Re: Radio Switcher for Jolla (2G-3G-4G)
 

Well, they most certainly can ban all phones from one manufacturer. Blacklisting is done by IMEI, so its easy (and have been done here in DK) to blacklist a series of IMEIS.

Re: Radio Switcher for Jolla (2G-3G-4G)
 

That is why I want to know if this Radio Switcher app is still vulnerable for this issue...

Re: Radio Switcher for Jolla (2G-3G-4G)
 

Messages I have got from Jolla staff have all been positive regarding this Radio Switcher and nobody has asked or even mentioned anything like that.

Of course that talk is pretty much true what comes to banning devices and badly behaving cellular radios. This device however is a derivate of an Orange phone, or so I have been told by Jolla staff, and it uses Qualcomm hardware and cellular modem software which all have been certified, AFAIK. There can be interference and high radiation levels on short range because of possible differences in PCB and component layout and protection compared to that Orange product and LTE modem may require some tuning before LTE capability can be deployed.

I do not know for sure. Anyway second post in this thread was not about that this application should not be used but where to get the source code.

Re: Radio Switcher for Jolla (2G-3G-4G)
 

Turns out Virgin hadn't enabled my 4g, hence the app not working

No problems now
