What is the problem?
I use my iPhone X for the 4th day, everything was good but today I had something strange a few times. I unlock my iPhone with password (Face ID is off) and while unlocking it it stopped, grey display appeared and in the middle it started making a sign like when something is loading. It lasts 2-3 seconds then my locked display came back. I’m worried. What’s worng with my phone? Thanks in advance.
