LG Optimus 4X HD
Will Samsung Galaxy Note OutPlay LG Optimus 4X HD

LG has unveiled its first quad-core smartphone - the LG Optimus 4X HD. The phone comes with touch-sensitive controls and, in a recent benchmark test, performed better than the HTC One X. The Optimus 4X HD packs interesting features like a faster processor and a high-resolution camera.

However, it will face tough competition. There are already a number of exceptional smartphones out there, one of which is Samsung's Galaxy Note and its amazing S Pen.

Check out how the two stack up


The LG Optimus 4X HD flaunts a HD-IPS capacitive touch-screen with a resolution of 1280 x 720 pixels at 312 pixels per inch (ppi).

In comparison, the Galaxy Note touts a Super AMOLED capacitive touch-screen with a resolution of 1280 x 800 pixels at 285 ppi. The Corning Gorilla Glass protects the screen from scratches and dust and it incorporates the TouchWiz 4.0 User Interface (UI) which includes visual improvements such as hardware accelerations and gesture-based functionality.


The Optimus 4X HD is powered by a 1.5 GHz Cortex-A9 quad-core CPU and the ultra-fast Nvidia Tegra 3 chipset, which reportedly delivers excellent performance with faster browsing and hardware-accelerated flash capabilities.

In contrast, the Galaxy Note is powered by a 1.4 GHz ARM Cortex-A9 dual-core CPU and the Exynos chipset. It contains the Mali-400 GPU which offers a complete graphics acceleration platform as well as maximising battery life. Moreover, Mali-400 reduces memory bandwidth overhead and lowers power usage.


Both smartphones come with an eight megapixel rear-facing camera that shoots at a resolution of 3264 x 2448 pixels. The camera features in the LG smartphone are geo-tagging, face and smile detection, touch focus and image stabilisation. It offers full HD video recording at 1080p and has a 1.3 megapixel front-facing camera for video calling.

The Galaxy Note's camera features AutoFocus and LED flash and the camera can self-adjust to take smile shots as well as panorama shots. It includes a secondary camera of two megapixels for video chats as well as 1080p video recording.

Operating System

The LG Optimus 4X HD runs on the latest Android 4.0 Ice Cream Sandwich (ICS) operating system, which features rich notifications, multitasking and customisable home screen and widgets.

On the other hand, the Galaxy Note runs on Android 2.3 Gingerbread operating system which can be upgraded to the latest ICS.


Both smartphones have 16GB of internal storage and a microSD card slot for an additional memory up to 32GB.


The LG smartphone includes Wi-Fi 802.11 b/g/n with Wi-Fi hotspot as well as Bluetooth wireless with A2DP technology, while the Galaxy Note features Wi-Fi 802.11 a/b/g/n as well as offering support to Bluetooth 3.0 + HS wireless technology.


The Optimus 4X HD has a Li-Ion 2140mAh standard battery. Samsung's Galaxy Note includes a Li-Ion 2500mAh standard battery which allows stand-by time of up to 960 hours on 2G and 820 hours on 3G networks. It supports talk time of up to 26 hours 10 minutes on 2G and 13 hours 30 minutes on 3G networks.
