💡 What’s Changed the Most?

📲 What’s Next?

• Fully AI-powered assistants that handle tasks autonomously

• More advanced spatial computing (AR + AI)

• Chip-level AI enhancements for battery, camera, and UI

• Ultra-secure biometric ID systems (eye, vein, behavioral)

• Devices that adapt to you—not the other way around

✅ Final Thought:

The last decade redefined what a phone can do.
The next might redefine what it means to even have one.
