LG is set to launch the G Flex tomorrow in Korea (for about $940), and according to this new video, the device actually flexes a little (you have to apply some force, though):
The G Flex has a 6" 720p RGB flexible OLED display made by LG Display. We know it is based on a plastic substrate, but it isn't known when it is covered in plastic or in a curved glass (like Samsung's Galaxy Round). If it flexes it makes sense this is an all-plastic device. But then it should have been "unbreakable" too, but LG never mentioned this in any PR so it is strange.
Other features of the G Flex 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). LG is in talks with carriers to bring it to the US, Europe and Japan.
If they would market it as unbreakable, it wouldn't take 5 minutes before the first guy hits it with a mallet, breaks it and posts the video on YouTube. The thing is not unbreakable and LG would be downright stupid to market it as such in todays world.
As for the video...yawn...so you can bend the thing forcibly by a couple of millimeters. That doesn't even mean it is all-plastic, after all a lot of materials can be slightly bend even glass if the radius is big enough.
