The livestream audience was buzzing.
They'd seen the specs. They'd heard about the chip, the cameras, and the charging. Now, all that was left… was the price.
But instead of revealing it, Liu Jianyu slowly pulled out the phone.
"This," he said, "is the Harmony X2."
He held it up. The cameras zoomed in. Viewers leaned closer.
"It's big," someone commented.
"Love big phones."
"Wait… something's weird. Where's the camera? And the earpiece?"
The chat began to stir.
It took a few seconds, but then someone called it:
"It's… missing something."
Then, behind Jianyu, the big screen lit up with three golden characters:
Full-Screen Display
The chat exploded.
"FULL SCREEN??"
"No way."
"No notch, hole-punch, no buttons—what IS this??"
To casual viewers, the term was new.
But tech fans knew exactly what they were seeing.
"They did it."
"A real full-screen phone."
"No one else has this—not even Apple."
Jianyu's voice cut back in, full of pride.
"This is the Waterdrop Full-Screen Display. A screen without borders. Without distractions. Just pure, immersive glass."
The screen behind him switched again, now showing a bright, high-res image of the X2's front side.
It was exactly like the promo: nearly all screens were covered with a subtle, curved black teardrop shape at the top where the front camera sat.
That's where the name came from.
"Waterdrop," Jianyu explained, "refers to the camera notch—a minimal cutout shaped like a drop of water. It preserves screen integrity while allowing for full front camera functionality."
In Japan, where the design originated, it had once been nicknamed the Beauty Tip—a poetic nod to its elegance.
Now, CS has taken it mainstream.
This wasn't some theoretical prototype.
This was the world's first commercial full-screen phone.
The crowd went wild.
"It's beautiful."
"No home button, no chin—this looks like a concept render."
"How is Samsung still playing with punch holes?"
Jianyu stepped forward again.
"Let me show you how it works."
He picked up the Harmony X2 and mirrored the display onto the big screen.
"We've removed all physical buttons from the front: home, menu, back. But that doesn't mean functionality is gone."
"Instead, we've created two control modes."
He demonstrated both:
Classic Mode – digital buttons appear at the bottom of the screen, mimicking older Android layouts.
Gesture Mode – swipe-based navigation with no visible buttons, giving the user complete control via intuitive motions.
The crowd was stunned by how smooth it looked.
"But," Jianyu added, "there's one more thing."
He picked up the mic and gestured toward the phone again.
"For better tactile feedback, we've built in a linear motor."
To most viewers, that term meant nothing.
But Jianyu was ready.
Holding the mic close, he began typing.
Da-da-da. Crisp, subtle tapping sounds echoed through the stream.
The effect was immediate.
"What is that?"
"Real haptic feedback??"
"It sounds like physical keys!"
Jianyu nodded.
"The linear motor adds a physical response—sound and vibration—every time you tap or swipe. It simulates real button presses, even on a full-glass screen."
"We want you to feel the difference."
And they did.
The chat lit up with awe.
"This is nuts."
"Apple's haptics are good—but this might be better."
"It's like typing on a keyboard made of glass."
This was the final piece.
A screen with no compromise.
Gesture controls with no lag.
And now… tactile response with no buttons.
Liu Jianyu looked across the livestream, satisfied.
He had just unveiled every last spec of the Harmony X2.
All that remained… was the price.
The audience knew it was coming.
They were glued to the stream, hearts pounding.
Because what CS had just shown them—
It was real full-screen, Real black tech, and a real problem for Samsung and Apple.
Was the post CS made ten days earlier? The one mocking the "strongest phone of the year"?
It was all true.
