The role of smartphones in life

Entertainment and content creation**
1. **Popularization of streaming media**: Netflix and Spotify provide personalized audio and video recommendations, and short videos (TikTok) reshape entertainment consumption habits.
2. **The era of universal creation**: Mobile photography (ProCam App) and editing tools (Jianying) lower the threshold for content creation, and ordinary people can become self-media creators.
3. **Socialization of games**: Mobile games such as “Honor of Kings” have both entertainment and social attributes, forming an online community culture.

Health management and medical assistance**
4. **Personal health monitoring**: Built-in sensors record steps and sleep, and cooperate with Apple Watch to monitor electrocardiograms and warn of health risks.
5. **Telemedicine**: Platforms such as Ping An Good Doctor provide online consultations, and patients with chronic diseases can have regular follow-up visits and obtain electronic prescriptions.
6. **Mental health support**: Meditation applications (Headspace) and psychological counseling services (BetterHelp) relieve the psychological pressure of modern people.

Seventh, key roles in special scenarios**
7. **Emergency response**: Earthquake early warning systems (such as Japan’s Yurekuru) and emergency rescue functions (SOS emergency contact) save lives.
8. **Accessibility support**: Screen reading (TalkBack) and hearing aid compatibility functions help people with disabilities integrate into the digital society.
9. **Travel and cultural exploration**: AR navigation (Google Live View) and audio guides for scenic spots (Sanmaoyou App) enhance travel experience.
