Intermittently, I will have my phone miss calls (even when I’m using it). The only reason I know I’m missing calls is that I will occasionally receive a notification for a voicemail after the fact from the caller. The phone never rings or provides any notification of a missed call and there is no information in my caller log even indicating that I missed a call.
I have an ASUS Zenfone 6 and it has worked just fine otherwise (call quality is great when I use it, I typically can send/receive texts, though I have experienced some occasional issues with receiving them, as well).
Any assistance would be appreciated.
