In my own experience, this could be a software bug. Please check on different software to see if the error appears on all applications, if it is always fixed at one point, then this is definitely a hardware error, now you need to bring the phone. this phone to an Apple service center for processing. In case of software failure, you can manually reinstall the new software.
