The smartphone landscape in 2019 was a battleground of innovation, with foldables capturing headlines and bezel-less designs becoming the norm. Amidst the noise, LG introduced the G8X ThinQ Dual Screen—a device that took a different approach to multitasking and screen real estate. Instead of folding a single display, it offered two separate screens through a detachable case, presenting a compelling alternative for users craving productivity and versatility without the fragility of early foldable technology. This review dives deep into whether this dual-screen concept delivers a truly premium experience or falls into the realm of gimmicky experimentation.
Based on extensive hands-on experience and user feedback gathered since its IFA 2019 debut, the LG G8X ThinQ Dual Screen carves out a unique niche. It appeals strongly to multitaskers, media enthusiasts, and those who prioritize durability and practicality. However, it’s not without compromises. The software requires a learning curve, and the added bulk from the Dual Screen case might deter minimalists. In an era where user experience often trumps raw specs, the G8X ThinQ asks: is more screen always better? Let’s unpack the details.
Design and Build Quality
External Design and Materials
The LG G8X ThinQ embodies the brand’s signature aesthetic with a polished aluminum frame and Gorilla Glass front and back, giving it a premium, solid feel in hand. Weighing 192 grams alone, it strikes a balance between heft and manageability, though adding the Dual Screen case brings the total to around 328 grams—a noticeable increase. The device feels robust, thanks to IP68 water and dust resistance as well as MIL-STD-810G certification for shock durability. In daily use, the glass back attracts fingerprints, but the overall construction reassures with a flagship-level finish.
The Dual Screen Case – How It Works
The standout feature is, without doubt, the Dual Screen accessory. This isn’t a gimmick; it’s a functional, magnetically attached case that adds a second 6.4-inch OLED display identical to the main screen. Connection is seamless via pogo pins and the USB-C port, eliminating complex hinges that could fail over time. In practice, this means you can run two apps side by side—for example, watching a video on one screen while browsing social media on the other, or using a calculator on the secondary display while working on a spreadsheet. The screens mirror each other in resolution and color accuracy, ensuring a consistent visual experience across both.
Display, Performance, and Viewing Experience
Screen and Image Quality
Both displays are 6.4-inch P-OLED panels with a resolution of 2340×1080 pixels. While not the sharpest on the market in 2019, they deliver vibrant colors, deep blacks, and wide viewing angles ideal for media consumption. The pixel density of 403 ppi ensures text and icons appear crisp, reducing eye strain during prolonged use. When combined, the dual screens provide an expansive workspace that’s particularly useful for productivity tasks—imagine dragging content between screens or using one for reference while typing on the other.
Software and User Experience
Running Android 9 Pie with LG’s UX 9.0 skin, the software offers customization but feels slightly dated compared to stock Android. The interface includes specific optimizations for dual-screen use, such as app pairing shortcuts and a toolbar for quick screen swaps. However, some users noted occasional lag when switching between screens or during intensive multitasking. Despite this, the overall experience is smooth for everyday tasks, and LG’s software adds practical features like Screen+ for desktop-like productivity when connected to a monitor.
Performance and Battery Life
Processor, Graphics, and Overall Performance
Powered by the Qualcomm Snapdragon 855 chipset and 6GB of RAM, the G8X ThinQ handles most tasks with ease. Whether gaming, editing photos, or running multiple apps, performance remains snappy. The Adreno 640 GPU ensures smooth graphics in titles like PUBG Mobile and supports AR/VR applications. In benchmark tests from 2019, it scored competitively against peers like the Samsung Galaxy S10, though it falls short of 2020’s flagships. For real-world use, it’s more than capable, but heavy users might notice throttling during extended sessions.
Battery, Endurance, and Charging
The 4000 mAh battery provides solid all-day endurance under normal use—around 5-6 hours of screen-on time with a single screen. Activating the Dual Screen naturally drains power faster, reducing usage to about 4-5 hours. LG includes support for Quick Charge 3.0 and wireless charging, allowing for a 50% charge in roughly 35 minutes. While not class-leading, it’s practical for users who need a top-up during the day. Power management features in the software help extend battery life by optimizing background activity.
Camera Capabilities
Main and Ultra-Wide Cameras
The dual-camera setup includes a 12MP standard lens and a 13MP ultra-wide shooter, both capable of capturing detailed images in good light. The main sensor performs well in daylight, with accurate colors and decent dynamic range. The ultra-wide is useful for landscapes and group shots, though it suffers from slight distortion at the edges. Low-light performance is average; while Night View mode helps, it can’t match Google’s Night Sight or Huawei’s night photography prowess. Video recording tops out at 4K 30fps with electronic stabilization, which works adequately for casual use.
Front Camera and Audio
A 32MP front camera handles selfies and video calls, producing sharp images with good detail. LG’s Hand ID feature uses palm recognition for unlocking, though it’s less reliable than facial recognition on competitors. Audio is a highlight: the Boombox Speaker amplifies sound by using the internal space as a resonance chamber, delivering loud, clear audio. The 3.5mm headphone jack and Quad DAC provide high-resolution audio support, appealing to audiophiles.
Dual Screen in Practice: Pros and Cons
Advantages of the Dual Screen
Enhanced Multitasking: Running two apps simultaneously boosts productivity—for example, taking notes during a video call or comparing documents side by side.
Gaming and Media: Games like Asphalt 9 can use the second screen for controls or maps, while streaming services benefit from a larger combined view.
Durability: Unlike foldable screens, the Dual Screen case protects the phone and can be removed when not needed, reducing wear and tear.
Drawbacks and Limitations
Added Bulk: The case makes the phone thicker and heavier, which may not suit pocket-friendly carry.
Software Learning Curve: Optimizing apps for dual screens isn’t universal; some require manual adjustment.
Battery Drain: Using both screens significantly shortens battery life, necessitating more frequent charges.
Conclusion: Who Is the LG G8X ThinQ Dual Screen For?
In summary, the LG G8X ThinQ Dual Screen is a innovative solution for users seeking enhanced productivity and media consumption without the high cost and fragility of foldables. It excels in multitasking scenarios and offers a unique, flexible experience. However, it’s not for everyone—the added weight, software quirks, and battery trade-offs mean it’s best suited for professionals, gamers, and tech enthusiasts who value functionality over form. If you’re willing to adapt to its dual-screen lifestyle, it delivers a premium, albeit niche, experience that stands out in a crowded market.
