SFOS 220.127.116.11 on Xperia 10 Dual SIM did run perfect since it was released, but since abt. a week frequently the touchscreen sticks or freezes and no further input or operation is possible.
Restart the screen by Hilfsprogramme did not help.
Rebooting the phone by power off … power on also did not help.
edit: switching the phone to standby by short-pushing the power button, and switch on again wakes up the touchscreen for the next 2 or 3 operations and then the touchscreen stucks again.
This occurs while running the phone as internet access point with data connection + VPN + Mobile access point on.
This is for what i mostly use the phone. Other situations not tested since this occurs.
Does anyone know whats the matter here?
