Hello how may I help you? I need help managing my phone settings. I can help you with that. What do you need help with? I need to study for exams, and I do not want to get interrupted. You can turn on the do not disturb feature, but it will disable all currently set alarms and notifications. Please turn it on. I really need to focus for my exams. Okay. Do you want me to turn on the do not disturb now? Yes, right now. The do not disturb feature has been activated. Is there a way to set it up for four hours, or do I need to turn it off myself when I want to? I can set it up for a particular length of time, or just ask me when you want to cancel the feature. Please set for four hours.
