I plan to do so when I have time.

I just read through this post and want to add that lately, I have that exact issue on my Volla X (24.04-1.2 stable).
I'll test the script and report back.

In my case this goes hand in hand with not being able to receive calls. I can initiate calls, but it takes around a minute until a call is established (until the ring sound).

@pparent Hello. Thanks for the script. Did you notice side effects (you said that, i have a Volla 22 too) ?
May you please suggest a complete procedure to test (as done here https://forums.ubports.com/topic/6211/howto-alternate-way-of-saving-battery-when-using-4g-lte ) ?
Thanks in advance.

The only thing that I've noted so far, is that If I enable airplane mode with a wrong timing (bad luck), it might go into a loop of disabling / re-eabling the modem. But then I switch off and on, the airplane mode it goes fine.

1°) With adb create the script with

nano /home/phablet/backup-ip.sh

and paste the content

2°) Give execution rights:

chmod +x /home/phablet/backup-ip.sh

3°) Start the script with:

sudo su -c "/home/phablet/backup-ip.sh > /home/phablet/log-backupip 2>&1 &"

It will then be running until next reboot.

I've reported the bug here:

@pparent added some comments.

@pparent i test the script in train..

domubpkm

@pparent Given that the conditions are particularly detestable on the train, I can say that the script passed the test with success: I always managed to recover the network at various times without any action on my part even if it was not immediate given the moving train and the constant change, I suppose, of relay towers.

@domubpkm

Great!

In any case in a train you cannot expect a perfectly stable connection!

domubpkm

@pparent Yes the script works well. However, maybe a side effect that I noticed (not in the train) : VoLTE and cellular data use different APNS from what I understood. So, without the script, I have Volte enabled even though cellular data is off. When the script is enabled, VoLTE only works if cellular data is enabled.

Edit : What is the command line to stop the script without reboot or stop restart of the Volla 22 ?

pparent

@domubpkm

To stop the script:

sudo pkill backup-ip.sh

It's true that I've not taken into account the case where LTE is activated, but mobile data is disabled.

Have you filed a bug somewhere ?

Notice issues with F

@kugiigi said in Looking for Testers: Ubuntu Touch 26.04-1.x (Early version):

@lduboeuf Do we have the new contacts backend and syncing in 26.04?

Yes all seems to work.
Not easily testable though since it needs some ubports-qa + apt installs for now

lduboeuf

did you reported the issue to the porter ?.
i personaly have some issues on FP4 regrding network too:
e.g Noticed that QNetworkConfigurationManager

I've not understood the quotes about 26.04!

pparent

By the way I've personally installed the script in a way that stands in time by creating a systemd file:
( Because it improves a log my day-to-day experience)

/etc/systemd/system/backup-4g.service :

[Unit]
Description=LTE backup Service
After=network.target

[Service]
Type=simple
ExecStart=/home/phablet/backup-ip.sh
Restart=on-failure
WorkingDirectory=/home/phablet/

[Install]
WantedBy=multi-user.target

and then

sudo systemctl enable backup-4g

So that it starts automatically at startup.

For this to work you need to have the script that I have posted above in /home/phablet/backup-ip.sh

ouch that comes from InTouch app, it has posted in a random topic lol, will delete it

Note that in 24.04-2.x dev, the problem is exactly the same on volla 22. And my perception is that the problem is magnified

Do you mean in 24-04-2.x?

Now I'm that I'm running the script it's much better for me. But I still observe the following:

-Sometimes the connexion is abnormally slow, I'm not sure if it comes from the operator, the coverage or the phone. Now the priority is maybe given to 5G...

-LTE does not reconnect properly most of the time after a connexion loss.
