Cell-id info no longer returned via dbus calls in SFOS 4.2

REPRODUCIBILITY (% or how often): 90-100%
BUILD ID = OS VERSION (Settings > About product): 4.2.0.21 (Verla)
HARDWARE (XA2, X10, X10 II, …): XA2 Plus Dual SIM
UI LANGUAGE: English
REGRESSION: (compared to previous public release: Yes, No, ?): Yes

DESCRIPTION:

I have a background program active which act based on cellid’s. I noticed this was no longer working and that it stopped working exactly after the upgrade to 4.2. It uses dbus commands.

Some dbus commands that return no data anymore:
dbus-send --system --print-reply --dest=org.ofono /ril_0 org.nemomobile.ofono.CellInfo.GetCells
dbus-send --print-reply --system --dest=org.ofono /ril_0 org.ofono.NetworkMonitor.GetServingCellInformation

It returns an empty array (same goes for my second SIM, ril_1). The first command does return some result maybe 1 out of 20 times, the second one always returns an empty array.

PRECONDITIONS:

Upgraded to SFOS 4.2

STEPS TO REPRODUCE:

  1. Issue the dbus commands.
  2. Maybe someone who has not upgraded to 4.2 can confirm it still works on their device? Or does it work for others on 4.2?

EXPECTED RESULT:

Array with cell info

ACTUAL RESULT:

Empty array

ADDITIONAL INFORMATION:

Seems to work fine for me on 4.2.

Thanks for testing. It was tested of an XA2 or an other model?
I was actually able to get a result from the second command a few minutes ago for the first time, but now it is returning an empty array once again. Can’t imagine it is hardware related, as it worked fine before the 4.2 upgrade. It could be related to some corrupted software component then, no idea really.

Xperia 10 II here. 

Still broken in 4.3.0.12.

Saw some warnings passing during the upgrade, no idea if it is related:

@adekker:
I tried with 4.3.0.12/X10ii and both dbus commands worked fine.
I also tried with 4.2.0.21/XA2 (h4113, one SIM) and the commands worked in this case, too. However, the first try of the first command did not give a proper output but after that, it worked fine.

First try was empty too, XA2, 4.2.

X with 4.3 works fine.
Also on first try.

Your finding and the response of @amaretzek confirms for me that it does not work as pre SFOS 4.2. Before 4.2 I would always get a response, now it has become russian roulette.

And the least chance of getting a response seems to be when the device is in sleep mode. I am running a background process that performs actions based on cellid using this commands, and I immediately noticed it stopped working after my upgrade to 4.2

Have the same problem for a while now. Maybe even earlier than 4.2.
Xperia 10, 4.3.

And… not fixed in 4.4.0.58 :frowning_face:

And… not fixed in 4.4.0.64 :frowning_face:

Do you have a XA2 or a XA2 Dual SIM?
