As a disclaimer, I've tested the 3 GB RAM variant of this device with 32 GB of internal storage on the inside. (androidheadlines.com)
It is possible that the company may introduce a 6 GB RAM variant of the device, which will arrive with 64 GB of internal storage. (androidheadlines.com)
Only the Black color variant of the device is available as of now. (gadgetian.com)
