[4.1.0.24][Xperia 10ii] Android apps cannot use mobile data

[fridlmue]

I have the strong feeling(!), that this workaround helps also with this Problem: [4.1.0.24][Xperia 10II] No Internet connection on Mobile Data when leaving WiFi if `Data acces point`: `Protocol` is set to `Dual` (default)
Perhaps it is worth a try!
