The 4.7" display phone features a 2 GHz NVIDA Tegra 4i ARM Cortex-A9 quad-core processor with 60 GPU cores, 1GB RAM and 16GB storage [more specs]. The OS is a customized version of Android called PrivatOS which offers encrypted calls, texts and emails that can’t be unscrambled even by spy agencies. It also offers built-in resistance against malicious software which will be most welcomed for users worried about free Apps that are becoming increasingly invasive, if not pure data collection spyware for unknown 3rd parties. The Blackphone will retail at around £375 in the UK (or $629 in the US) and will be on sale this coming June.
