The Verdict

When we look at the LG Optimus 4X HD and its competitors, Samsung’s Galaxy S3 and HTC’s One X, it’s a safe bet that the quad-core Tegra will beat their dual-core processors.
Even from a technical point-of-view, there is little to find lacking in the Optimus 4X HD. Its screen is great and very generous in both resolution and dimensions. The IPS technology makes it very nice to use as well. The Tegra 3 is a great processor which delivers smooth performance in UI navigation as well as app utilization and web browsing. The software is nice and the Optimus UI is simple to use and nice looking as well.
The downside to the Optimus 4X HD would be an industrial design that is a bit boring, a few crashes and inconsistencies found in the user experience, but otherwise, we found nothing to complain about.


All in all, the LG Optimus 4X HD is a flagship that is a worthy competitor for its slot in the high-end smartphone market. The choice comes down to personal preference.
