As someone who has been on both sides of tech support calls, I know how much people hate hearing the question “Have you rebooted?” or pressed reset, or whatever it takes to make the device go through its standard protocols.
But it does fix things, as I was reminded of once again this morning. Last night, my phone decided that it couldn’t get a signal. It could- the phone was connecting and I could hear the other side, but they couldn’t hear me. Same problem this morning. So, I popped out the battery and popped it back in. All fixed.
