Help me with this issue
Consider a factory reset if not done since upgrading to Android 10. Backup your data (except the apps) to the cloud or a pc first. You should not backup or restore the apps as you could reintroduce the issue.
Factory reset it if the issue stil persist then visit service center
I think this is not software related issue this symptom looks like a part is failing which is causing these issue. Try to visit service center for better outcome
It is a software issue. I used to have it some time ago. The app used to crash and the phone beeped and restarted.
Make sure your phone is updated to the latest firmware. Contact oneplus support. Before trying factory reset or anything suggested by other people, try updating the apps that frequently led to your situation and get it touch with support from oneplus. Clear the caches
