Bug Description

On first boot when LTE is enabled (arale), I see the attached screenshot, where 2G is selected.

However, output of list-modems show umts as the selected technology, so 2G/3G should be the option selected instead:

/usr/share/ofono/scripts$ ./list-modems
[ /ril_0 ]
...
    [ org.ofono.RadioSettings ]
        ModemTechnologies = gsm umts lte
        FastDormancy = 0
        TechnologyPreference = umts
...

$ system-image-cli -i

I am able to reproduce this after rebooting:

1. Reboot
2. Open system settings and go to Cellular: 2G is wrongly selected (I see HSDP in indicator)
3. Close system settings
4. Open system settings and go to Cellular: now I have 2G/3G/4G selected, which is correct

I have seen the same issue in mako, with vivid-proposed. After boot, first time system settings is executed I see 2G set in Cellular page. Second time, I see the correct value (3G/2G).

Only difference being that there was no 4G tech in this case.

Raising due to possibility of this being an issue on all phones.

Neither me, nor Alfonso can reproduce this, using vivid, on mako, krillin and arale. It looks to me as this bug was due to libqofono 0.7 landing 14th of January [1] and full support of this libqofono version came 17th of February [2].

Until we can reproduce this, I'm marking it as invalid.
