SFOS shortcomings & workarounds for Xperia 10 II

Workaround : sometimes when after a reboot or after an airplane mode one of the two SIM or both, but usually one, has problem in finding the network and into the native Setting → Mobile network , the related Network field remain in searching . In this case degrade the network mode to 2G only. After the network will be found, switch to prefer 3G and then after the network will be found again, switch to prefer 4G . This seems a slower approach but in fact, it works around the problem⁰

• State : under investigation because new installation of Carriers Services, and its configuration might solve the problem.

After some tests that produced a great variaty of results, this is the best conclusion that I found.

The big difference is about restarting the SFOS network applications stack.

• Apps -> Settings -> Info:Utilities -> Restart Network Subsystem

This worst case can be solved adding the Uitlities to the TopMenu and in that case the workaround procedure would be

• Airplane mode off, Utilities → Restart

PROPOSED MITIGATION

The Restart Network Subsystem is the key-workaround and probably it would be better to have an option for each SIM to do it automatically when the airplane mode is switched off.

This approch is working also for the issues derived from switching 4G with WiFi connections or viceversa.

@robang74

Workaround : sometimes switching on/off/on from 4G and Wifi or viceversa, the Android apps cannot see the internet connection. In such a case, switch to airplan mode and then back to restore the full connectivity.

• State : under investigation because new installation of Carriers Services, and its configuration might solve the problem.

The “airplane mode” workaround can lead to more problems rather than the one is pretending to solve. Thus restarting the SFOS networking subsystem should be added in some place from which users can access quickly and easily. Because in this specific case a netwrok reset added as automatic default in switching seems a counter productive idea that slowdown a frequent and common operation.
