My apple went black when it was cold for 4 days, so I could only press the HOME+ shutdown button to start it, but it crashed when it was so cold in winter. What did you say?/Sorry?

Electronic equipment does have a normal working range, and problems will occur if it is too cold or too hot.

So it's hard to say, or it may be that the ambient temperature is really too low-just put your mobile phone in your inner pocket when you go out.

If the fault still exists and can be reproduced, send it to the after-sales service department.
