LG announced that the G Flex smartphone will launch in Hong Kong next week - on December 13th. The phone will also launch in Singapore and Thailand in the following weeks. It will arrive in Europe in early 2014.
We also know that LG aims to bring the flexible OLED phone to the US, but we don't know when yet.
The G Flex has a 6" 720p RGB flexible OLED display made by LG Display that is curved from top to bottom (unlike Samsung's Galaxy Round which is curved from left to right). Other features include a 2.3Ghz Snapdragon S800 CPU, 2GB of RAM, 32GB of internal memory, a 13MP camera, NFC, Android 4.2.2 and a 3500mAh non-removable battery (LG Chem's curved battery). The G Flex has two rear-mounted buttons and a "self-healing" back (that will heal scratches quickly).
