The LG Optimus 3D (or LG Thrill 4G in the USA) is a 3D-enabled Android 2.2 Froyo (Android 4.0 Ice Cream Sandwich upgradeable) 3D mobile device released on 7 July 2011 in the UK and advertised as the world's first full 3D mobile phone. It has 512 MB of RAM and 8 GB of onboard storage, which can be expanded by up to 32 GB using a micro SDHC card. The phone features two 5 MP back-facing cameras that are capable of filming 720p 3D and Full HD 1080p in 2D, while pictures taken in 2D mode are 5 MP and 3 MP when taking a 3D picture. It also includes a VGA front-facing camera for video-calling. The phone features a 3D user interface which allows the users to access 3D content, such as YouTube in 3D, 3D games and apps, or 3D gallery with a push of a button. Tri-dual technology The LG Optimus 3D showcases LG's "tri-dual" technology: dual-core, dual-channel and dual-memory. It receives significant performance benefits as a result of the faster transfer of data between the dual-core and dual-memory. This enables users to browse web pages, multitask between computer programs, play games at a higher frame rate and enjoy movies more smoothly. 3D hot key Along with a range of other features, the LG Optimus 3D also provides a 3D Hot Key for instant access to the dedicated 3D menus. It allows users to switch from 3D to 2D, or 2D to 3D. With the latest Gingerbread update, the 3D Hot Key can be used as a camera shutter for taking pictures conveniently. 3D applications The LG Optimus 3D comes with a range of different 3D applications, ranging from the latest games to a 3D Gallery. Unlike its competitor the Evo 3D, it has a 3D user interface which enables users to navigate through the features in 3D. The glasses-free 3D effect is generated by a parallax barrier screen. On 15 November 2011, LG announced an enhanced version of Gingerbread customized for the Optimus 3D. LG claims it enriches the 3D experience and adds the ability to do 3D video editing. Content sharing The LG Optimus 3D is capable of sharing and viewing 3D videos on the large screen, with an HDMI 1.4 connection to 3D equipped TVs or monitors and with DLNA certified-compatible products. This allows users to show their own captured 3D content in
