Looks like LG is updating its G Flex 2 set in Singapore (model no. H959) with a new software version 15b. This is a small update for a device already on Android 5.1.1, and LG says that the update would improve the G Flex 2’s usability and functionality.
The build date of the v15b update is Jul6 16, 2015, so it maybe the latest software from LG’s team right now. Thanks to caysman for sharing this!
