    My One Plus 3T randomly freezes while doing any kind of operation. The screen goes blank and clicking any button doesn't work. I have to manually press the volume down and power key button to prompt the reboot mode. Later it works fine . This happens once in a week or so.

    Please provide expert opinion.
