Cannot answer calls
First I had to address the redundancy. It's a XS. The X is the Roman numeral 10, so 10X is 10 10, or 20. We'll just chalk it up to a typo. 😉
Can you explain, "can't answer calls" please? Are you unable to hear ringtone? Unable to swipe to answer? If yes, is the screen saying locked? Screen unresponsive?
please detail the problem.
