Overview

When released in late 2019, the LG V50s ThinQ 5G offered a practical alternative to the first wave of fragile, expensive foldable smartphones. Rather than bending a flexible display, LG introduced a secondary screen attachment that connected directly to the primary chassis, offering genuine side-by-side multitasking for gamers, power users, and productivity enthusiasts.

Today, long-term ownership of the V50s ThinQ 5G is defined by LG's departure from the mobile market. Without official brand service centers or software updates beyond Android 12, maintaining this device requires proactive care and hardware awareness. Anchored by a Qualcomm Snapdragon 855 processor, 8GB of RAM, and 256GB of internal storage, the device still holds up well for daily tasks, but keeping its dual-screen workflow intact requires monitoring key failure points like battery swelling and charging port stress.

Design and build

The LG V50s ThinQ 5G sports a classic glass-and-metal sandwich construction, pairing Gorilla Glass 5 on the front with Gorilla Glass 6 on the back, framed by polished aluminum. At 192 grams for the base phone, it feels sturdy and balanced in the hand. However, snapping on the secondary display case significantly increases bulk and weight, transforming it into a pocket-thick multi-monitor rig.

Unlike modern flagships that have stripped away legacy ports, the V50s retains a 3.5mm headphone jack alongside a dedicated microSD expansion slot. The rear camera module sits almost completely flush with the glass back panel, protecting the lenses from direct surface scratches when placed flat. The primary design bottleneck lies at the bottom of the device: the single USB Type-C port handles charging, data transfer, and the display signal pass-through for the Dual Screen accessory, making it a critical hub for physical stress.

Everyday performance

Despite its age, the Qualcomm Snapdragon 855 chipset combined with 8GB of RAM provides adequate headroom for daily application workflows. Web browsing, media streaming, and routine social apps operate smoothly. Multi-window productivity remains the phone's standout feature—running a navigation map on one panel while keeping messaging or documentation open on the second display works seamlessly without severe thermal throttling.

Software responsiveness is generally good on its final Android 12 release, though modern heavy mobile games will force the system to dial back graphics settings to maintain stable framerates. The main 6.4-inch OLED display delivers rich contrast and vivid colors, matched closely in tint by the Dual Screen housing panel, though minor color temperature variance between the two screens is a common operational quirk.

Battery, durability, and longevity

The internal 4000 mAh lithium-polymer battery was well-sized for single-screen operation in 2019, but driving two bright OLED panels on active cellular networks creates substantial power draw. Over prolonged ownership, high thermal loads accelerate chemical battery degradation. Users often experience shortened runtime, sudden percentage drops under heavy multi-tasking loads, or slight physical swelling.

When a battery swells inside the V50s, it exerts outward pressure on the glass back panel, potentially compromising the water-resistance seal or unseating internal press-fit connectors. Keeping an eye on panel gaps or unexpected drain patterns is essential.

Common issues owners hit

Several hardware trends emerge among long-term LG V50s ThinQ 5G users:

• USB Type-C Wear: The constant physical insertion and removal into the Dual Screen housing weakens the solder joints and internal pins of the USB port, causing intermittent charging or loss of secondary display output.
• Battery Degradation & Swelling: Repeated high-power discharge cycles cause the 4000 mAh cell to lose capacity, sometimes bulging enough to lift the rear Gorilla Glass.
• Dual Screen Hinge & Connector Failures: The mechanical hinge on the attachment case can develop play, and spring-loaded magnetic connector pins may stop passing power reliably.
• OLED Burn-in: Display panels left running static launcher icons or navigation bars across long dual-screen sessions may exhibit permanent image retention.

Who it's for

The V50s ThinQ 5G is best suited for tech enthusiasts, bargain power-users, and multi-taskers who appreciate a dual-screen workflow without the structural vulnerability of folding screens. It is an ideal fit for users comfortable with self-maintenance, who don't require the latest Android software updates, and who value physical features like expandable storage and a headphone jack.

Bottom line

The LG V50s ThinQ 5G remains one of the most practical multi-screen mobile platforms from its era. While LG's exit from the smartphone market limits software updates, the underlying hardware remains versatile and usable provided you manage battery health and port fatigue carefully.
