screen touch not properly working
Do a full Erase/Delete Data button, factory reset. This will restore you to a fresh installation of 10.3.1. So you will need to backup your phone.
After Backing up the phone.
Go to Settings, System, Reset Options, Erase All Data, click on the Delete All Data button,
If that doesn't fix it, you may need to bring it to an approved OnePlus service center.
Sorry to hear you are having screen problems. In addition to the Service Centre, you can contact online customer support. Please pm me if you need further help.
