The latter, some might argue, is technically more advanced than the LG Optimus 4X (thanks to the newer Qualcomm quad-core Snapdragon SoC based on the Krait architecture and the 2GB of RAM onboard).
On the other hand though, the LG Optimus 4X HD has a microSD card slot and a 23 months warranty. Its other features include a 4.8in 1,280 x 720 pixel IPS display, 16GB onboard storage, an 8-megapixel camera, a front-facing one and a proprietary UI running atop Android 4.0 ICS.
The smartphone was launched last year but was quickly overshadowed by the Samsung Galaxy S3, by far the most popular Android-based superphone of last year.
But LG is set to come back with a vengeance as it forged the most-hyped up Android phone ever, the Nexus 4 and is said to unveil a slew of new smartphone for Mobile World Congress.
And who knows, maybe LG will even throw in its first Windows Phone handset ever in the mix to rival Samsung, Nokia and HTC. Check out our review of the LG Optimus 4X HD smartphone here.
