Hands-on with LG's 6.4-inch G8X ThinQ, an upgraded G8 with a secondary display case that transforms LG's flagship into a dual-screen handset
Context & Ripple Effects
LG is extending the dual-screen experiment it started in February, when the V50 ThinQ launched with a 5G-focused Dual Screen accessory that clipped a second OLED onto the phone like a case. The G8X ThinQ applies the same idea to the mainstream G-series: a larger 6.4-inch upgraded G8 designed around a bundled secondary display rather than sold as a standalone slab.
That matters because LG has been iterating on split-screen multitasking since at least the G6's FullVision display with dedicated split-screen UX — the G8X is the first time the hardware itself carries half the screen real estate instead of the software slicing one panel. Engadget's early take now sits ahead of The Verge's full verdict on how the concept holds up.
First-order effects
- Buyers of LG's G-series flagship get a dual-screen handset without paying foldable prices — the second screen ships as a case accessory rather than new display engineering inside the phone.
- The Dual Screen accessory moves from being a niche 5G add-on tied to the V50 into the default configuration story for LG's mainline flagship.
Second-order effects
- LG is effectively betting its differentiation on accessories and multitasking rather than the spec race — the follow-up review's finding that the software is 'half-baked' puts pressure on LG to fix the layer that makes two screens worth carrying.
- Rivals pursuing true foldables now face an alternative comparison point: reviewers judging dual-screen phones on multitasking value and battery life, categories where a cased second screen competes on price.
Third-order effects
- If the pattern holds, flagship differentiation shifts toward modular multi-screen configurations — but the G8X's mixed reception suggests the constraint is less the hardware than whether any maker can ship dual-panel software that feels finished.
- For LG specifically, repeated accessory-based experiments (the G8's palm-scan and mid-air gestures, then the Dual Screen line) point to a strategy of testing unconventional form factors on flagships before committing to them structurally.
The trend: Smartphone makers are using attachable secondary displays as a low-cost bridge to dual-screen handsets, buying time until foldable hardware matures.
