I have detected problem with losing of mobile signal (Sony Xperia 10, dual SIM, i4113, Sailfish X 3.2.0.14).

After the call (ended from my side) the signal is loss approx. of 10-40 seconds (no error message or "mobile network error", etc.). No 2G, 3G or 4G (icon) available on the right upper corner of the home screen and not able to receive SMS or do phone calls.

And when I tried to retry or make a new call instantly several times in a row, the system crashed. Boot always ended with blank screen.

Trying the recovery mode was not successful - the LED only one time blinked in blue color and device had been automatically rebooted.

Only after removing the SIM and SD cards entering the recovery mode was successful. And then it was possible reflash the system again.

Now I am trying to avoid the scenario (patiently waiting for signal recovery :-), but the problem with signal loss persists.

Does anyone have the same problem?

[Update: 3.3.0.14]

The problem with signal loss in some circumstances persists.

No Signal loss here.

Did you run the device before with Android and had a SIM card inserted that connected fine previously?

@leszek : Yes, I did.

Same here. Today I can confirm radomly signal losses again and again on my Xperia 10 Plus with Sailfish OS 3.2.0.14

Same signal loses here and on the same dual SIM i4113, also never connects on 4G, even though in Android it connected on 4G+ at the same spot. Trying to use mobile internet almost freezes the current app. Stopping mobile internet immediately fixes it. When in Cellular Network in Settings and mobile internet is enabled, the internet status flashes constantly between connecting and connected. Fun. :)

My problem turned out to be (at least for now) old automatic GPRS settings set (I guess by provider). I've updated them to latest listed on their site and now 4G seems to work without a problem. I'll report back if something weird starts happening again.

I had this, but the latest update fixed it. It randomly started happening. I am on MetroPCS in the US.

Before the latest update and on my previous Xperia X it never happened.

Maybe the problem is (partialy) solved.

Yesterday my Xperia 10 crashed again. Then - after another reflashing - I did two things:

Signal losing in some conditions still remains.

As I notified in [Update: 3.3.0.14], the problem with signal loss (and sometimes with system rebooting) in some circumstances persists.

Workaround (not solution) seems to be switching the Settings->Mobile Network->Network Mode to "Prefer 3G".

Nothing of the sort here, sorry.

It seems to be okay. For the time being, there is no disruptive signal loss and system reboot when Network Mode is switched to “Prefer 3G”. Maybe a problem with Slovak Telekom (known issue with operators and their networks when devices attempt to switch between 2G/3G and 4G - the network is unable to handle the request to switch network bands calls/data): https://jolla.zendesk.com/hc/en-us/articles/202505018#13
