LG G Pro 2: A 5.9-Inch Phablet With Knock Code
The LG G Pro 2 arrived at a time when large-screen smartphones were moving from specialist devices into the mainstream. Its 5.9-inch display, powerful Snapdragon processor, and camera-focused design placed it between a compact tablet and a conventional flagship phone. For buyers in India, it offered a premium Android experience with more screen space than the LG G2 while remaining easier to carry than a full-sized tablet.
Announced in 2014, the handset continued LG’s interest in rear-mounted controls, slim bezels, and software features designed for one-handed use. The most recognisable addition was Knock Code, a security system that allowed users to unlock the phone by tapping a personal pattern on the display.
The G Pro 2 also reflected the period’s competition between major Android brands. Samsung was promoting its Note range, Sony was refining its Xperia phablets, and LG was preparing devices that would push display resolution and camera performance further. The result was a phone that combined practical hardware with several features that still feel distinctive today.
A large phone with a manageable shape
The 5.9-inch IPS LCD screen was the centrepiece of the G Pro 2. It used a Full HD resolution of 1920 × 1080 pixels, producing a sharp image for video, web browsing, photographs, and games. While it did not match the pixel density of smaller Quad HD panels, the display offered a useful balance between clarity and battery consumption.
LG kept the bezels relatively narrow, helping the phone avoid looking as oversized as its screen measurement suggested. The curved rear cover also made the device more comfortable to hold than a flat, angular handset. Even so, this was a broad smartphone, and reaching the far corners with one hand could be difficult for users with smaller hands.
The rear power and volume buttons remained a key part of the design. Placing these controls beneath the camera gave the front and side edges a clean appearance, while the index finger naturally rested near the buttons when holding the phone. This arrangement took some adjustment, but it became one of LG’s most recognisable design decisions during the period.
Performance suited to demanding Android use
Inside, the LG G Pro 2 used Qualcomm’s Snapdragon 800 chipset with a quad-core 2.26GHz Krait processor and Adreno 330 graphics. The combination was among the fastest Android hardware available when the phone launched. Opening applications, switching between browser tabs, editing images, and playing demanding games were all well within its capabilities.
The standard configuration included 3GB of RAM, which gave the phone useful breathing room for multitasking. Storage options varied by market, with 16GB and 32GB versions available, and a microSD card slot allowed users to expand capacity. That expansion was especially valuable for people who stored high-definition videos, music, and large photo libraries locally.
Connectivity covered the expected 2014 features, including 4G LTE in supported versions, Wi-Fi, Bluetooth, GPS, and NFC. Indian buyers needed to check the exact model number and network compatibility before purchasing an imported handset, since LTE bands and dual-SIM availability could differ between regional variants.
Knock Code made the lock screen memorable
Knock Code was the G Pro 2’s signature software feature. Instead of entering a PIN, drawing a pattern, or swiping across the lock screen, users tapped a sequence of areas on the display. The phone divided the screen into invisible sections, allowing a code to be created from two to eight taps.
The system worked even when the display was switched off. A user could tap the chosen sequence anywhere on the dark screen and unlock the phone without first pressing the power button. This made the feature quick in daily use and particularly convenient when the handset was lying on a desk or held in one hand.
Knock Code also offered a more discreet unlocking method than typing a password in public. It was not a substitute for stronger enterprise security, and users still needed a backup PIN or pattern, but it made everyday access faster. The feature later appeared on other LG phones, helping establish it as a defining part of the company’s Android interface.
LG’s Optimus UI included additional shortcuts, a dual-window mode, and tools for capturing screenshots or annotating images. Some of these functions were useful on a large display, although the software could feel busy compared with cleaner Android interfaces.

Camera hardware aimed at mobile photographers
The rear camera combined a 13-megapixel sensor with optical image stabilisation. OIS helped reduce blur caused by hand movement, especially in indoor photographs and evening scenes. This was an important advantage at a time when many smartphone cameras relied mainly on software processing and higher ISO sensitivity.
The G Pro 2 could record 4K video, giving it a feature usually associated with more expensive cameras and flagship phones. Storage requirements were high, however, and recording at that resolution quickly used the available internal space. A microSD card was therefore a practical companion for anyone planning to capture lengthy clips.
LG added several camera modes, including slow motion, burst shooting, panorama, and a background-blurring effect. The large display made composing photos easier, while the rear button placement provided a convenient way to take pictures. The front camera was less ambitious, but its 2.1-megapixel sensor was adequate for video calls and casual self-portraits.
The camera experience was strong in good light, though image quality depended on the scene. Fine detail could soften in low-light conditions, and aggressive processing sometimes affected natural colours. Still, the combination of OIS, 4K recording, and a large viewfinder made the phone appealing to users who treated photography as a major buying factor.
Battery life and everyday practicality
A 3,200mAh removable battery powered the handset. That capacity was appropriate for a 5.9-inch Full HD phone and generally allowed a full day of mixed use involving calls, messaging, browsing, photography, and video. Heavy gaming, constant LTE use, and extended camera recording could reduce endurance substantially.
The removable design was useful in a period when replacement batteries and spare power packs were still common buying considerations. Users could carry an extra battery for travel rather than relying entirely on a power bank. The trade-off was a slightly thicker body than some sealed flagship phones.
The Full HD panel also helped battery efficiency. LG had not yet adopted the Quad HD resolution later seen on the G3, whose display story is explored in LG’s Quad HD flagship. For the G Pro 2, choosing Full HD meant less strain on the processor and battery while still delivering a sharp viewing experience.
Audio performance was suitable for videos and speakerphone calls, although the single rear speaker could be covered when the phone was placed flat. Headphone users benefited from the standard 3.5mm port, an increasingly valuable feature for buyers who wanted to use existing wired accessories.
Software features balanced convenience and clutter
Android 4.4 KitKat provided the foundation for the G Pro 2, with LG’s custom interface layered over it. The user experience included themed icons, quick settings, custom widgets, and gesture-based tools. The interface offered extensive control, though some users preferred a simpler Android design.
The large screen made split-screen multitasking more practical. Reading an email while checking a calendar entry, or viewing a message while browsing a website, felt more comfortable than on a smaller handset. LG’s floating applications also allowed certain tools to appear above another app, although their usefulness depended on personal habits.
Software support is the main concern for anyone considering the phone today. Its original Android version is far behind current security standards, and many modern applications may no longer perform reliably. The G Pro 2 is therefore better understood as a historical flagship, a collector’s device, or an inexpensive second phone than as a primary smartphone for sensitive accounts.
Build quality and condition matter greatly on used examples. Buyers should inspect the battery, charging port, display for burn-in or scratches, camera glass, rear buttons, and microSD slot. A replacement battery may restore some of the phone’s original practicality, but compatible accessories and parts can be difficult to find.
Where it stood in the Indian market
The LG G Pro 2 occupied a premium price segment in India when it became available. Its cost reflected the Snapdragon 800 platform, 3GB of RAM, optical image stabilisation, and large Full HD display. Local pricing and stock varied, and imported versions could create uncertainty around warranty coverage and network support.
The handset was substantially more ambitious than entry-level models such as the Micromax Canvas 2 Plus, which targeted buyers seeking an affordable Android phone with respectable everyday performance. That contrast shows how wide the Indian smartphone market had become by 2014: manufacturers were competing simultaneously for first-time buyers and premium customers seeking flagship specifications.
For shoppers choosing between the G Pro 2 and a smaller flagship, the decision came down to priorities. The LG offered a larger canvas, a removable battery, expandable storage, and more comfortable video viewing. A compact device could be easier to operate with one hand and carry in a pocket, while a stylus-focused rival might provide better handwriting tools.
The phablet made the most sense for people who regularly watched videos, edited photographs, played games, or worked with documents on a phone. It was less suitable for buyers who valued compact dimensions, long-term software updates, or the lightest possible body.
What to check before buying one today
A used G Pro 2 can still demonstrate why large-screen Android phones became popular, but expectations should match its age. Its display, camera, expandable storage, and physical controls remain interesting, while its software and network support are increasingly limited.
- Check the exact regional model for LTE bands, dual-SIM support, and charging compatibility.
- Test Knock Code, the rear buttons, touchscreen responsiveness, and the proximity sensor.
- Confirm that the removable battery holds a useful charge and does not show swelling.
- Inspect 4K video recording, optical stabilisation, camera focus, and the microSD card slot.
- Treat the phone as a secondary or enthusiast device rather than a fully supported modern daily driver.
The LG G Pro 2 remains a distinctive snapshot of 2014 smartphone design. It delivered flagship-level processing, a generous Full HD display, a capable stabilised camera, and one of the era’s most memorable unlocking systems. Anyone researching the evolution of Android phablets, rear-button layouts, or mobile photography will find it an especially representative model.
