Why can't the mobile phone be copied and pasted? What's going on here?

The reasons for this situation are: network delay, cell phone jam and software problems.

1, network delay: unstable or slow network connection may cause the paste function not to work properly.

2, the phone is stuck: the phone is slow or stuck, which may lead to the failure of the paste function.

3. Software problem: Some applications may have software defects, resulting in the paste function not working properly.

You can try to restart the phone, and sometimes you can solve the problem that the paste function is invalid. Or clean up the background program.
