I noticed an issue today with my Zenfone. I have dual SIM and have selected "Always Ask" for Calls. Today I noticed that when I select a number for calling the pop-up menu is not visible and the phone feels hung. Actually its waiting for SIM selection to continue. Tried selected a one of the SIMs as preferred and it works fine. Interim fix is a reboot of the phone.
Not sure if anyone else phased this issue.
