No 4G connection and mobile data since update from 4.0

Bug Reports
1

REPRODUCIBILITY: 100%
OS VERSION: 4.3, 4.4
HARDWARE: X10
UI LANGUAGE: English
REGRESSION: ?

DESCRIPTION:

Since I updated from 4.0 to 4.4 (with steps to 4.1, 4.2, 4.3 and 4.4 in succession) I no longer have 4G reception. I only have 2G (as 3G is no longer available in my country).

It also seems that the mobile data connection is broken, despite the UI showing that I have a working mobile data connection. Seems that something in the OS is reporting that I have a data connection while I don’t.

Restarting networking through settings seems to temporary solve the mobile networking issue.

I have no clue how to get further diagnostics to investigate what might cause this issue.

PRECONDITIONS:

Sim inserted.

STEPS TO REPRODUCE:

Turning phone on.

EXPECTED RESULT:

4G reception, working mobile data connection.

ACTUAL RESULT:

No 4G, no working mobile data connection.

MODIFICATIONS:

Not that I am aware of.

ADDITIONAL INFORMATION:

During update process it asked something about packages reverting. But I had no clue what to do with this as 1. did not know the packages, 2. the UI gave me no options to make a decision what to do with the packages.

Thanks for the report, this is a bit similar case, so these instructions might help: After 4.4 upgrade no phone call no wlan possible - #20 by rainemak

Unfortunately that gives me the following:

Fatal error: ofono-ril-binder-plugin-1.2.6-1.4.2.jolla.armv7hl is already installed

I tried to post ssu lr to show my repositories, but this forum doesn’t allow me to do as I can only post 2 links as a “new user” :smiling_face_with_three_hearts:.

Edit: seems I can now:

Enabled repositories (global):

Enabled repositories (user):

Disabled repositories (global, might be overridden by user config):

Disabled repositories (user):

What other diagnostic info would be useful to assess the issue?

This week I have factory reset my phone without any difference.

After this I’ve flashed the Xperia 10 - dual sim with 4.5.0.19 to have a full clean start. Unfortunately this doesn’t change anything, still no 4G connectivity.

One thing to add is that I have seen some additional behavior in the past year. Sometimes the phone suddenly is able to connect to 4G. It would happen after the phone has been turned on for a longer time, e.g. longer than a month. It seems it remains being able to use 4G until the phone reboots.

This would indicate that it is not a hardware issue but a software issue.

Which log files should I look at to gain more insight in the possible issues?

I would say that oFono logs would be the first ones to check: Collect oFono Logs | Sailfish OS Documentation

Do you have some news about?

Sorry for the really late reply… Is this 4G problem still valid for you?

Better late than never: The phone still has the same issue, even after updating to SFOS 5.x.

My assumption is that it somehow is an hardware problem as it is also suffering from the touchscreen issues (see 4th Xperia 10 unresponsive screen ).

I’ve switched to a X10 III, so the problem is no longer really relevant :sweat_smile: .
