XXLSEC Ltd., the developer of the Privecall-TX device, has developed a near-identical, slightly bigger ProteusDevice, which runs the Linux 5.4 based PriveOS. The ProteusDevice handheld device (“not a mobile phone”) is said to have very tight security and was developed with secure access in mind.
The market is seeing more Linux handheld and phones such as the Purism Librem 5, the PinePhone “Braveheart” both of which are already in mass production. There are also other computing options with the handheld Pocket Popcorn Computer, which is much like the PocketChip, but decidedly improved and faster in general, as well as the Solectrix SX Mobile Device Kit which is more of a business option, for smartphone, opensource development with no cellular connectivity, but Gigabit Ethernet and USB-to-UART ports.
The ProteusDevice is in good company, and has a solid start, but is still a bit of a mystery, as to price and shipping. The phone will have end-to-end encryption and voice will be IP based. There is full protection against phishing, malware, ransomware, supply-chain attacks and unauthorized third party usage, reports XXLSEC.
The system is designed around an NXP i.MX6 ARM processor, and is equipped with 1GB RAM and 8GB eMMC. The battery has a capacity of 3500 mAh and is chargeable through the system connector or via micro USB cable.
