Blackphone


The Blackphone is a smartphone built to ensure privacy, developed by SGP Technologies, a wholly owned subsidiary of Silent Circle. Originally, SGP Technologies was a joint venture between the makers of GeeksPhone and Silent Circle. Marketing is focused upon business users, stressing that employees often conduct business using private devices and services that are not secure and that the Blackphone service readily provides users with options that ensure confidentiality when needed. Blackphone provides Internet access through VPN. The device runs a modified version of Android called SilentOS that comes with a bundle of security-minded tools. On 30 June 2014, the Blackphone began to ship advance orders.

Background

The concept of an encrypted telephone has been an interest of Silent Circle founder and PGP creator, Phil Zimmermann, for a long time. In a video on the Blackphone web site, Zimmermann said,
Aaron Souppouris of The Verge stated:
The Blackphone also allows insecure communications. Mike Janke, CEO and co-founder of Silent Circle, has suggested there are certain calls people want to encrypt, but "if you're ordering a pizza or calling your grandma", it's unlikely you'll feel the weight of criminals on your shoulders. "This is why Blackphone is unique — it gives the user the chance to choose the level of privacy."
Blackphone runs a custom-built Android OS called SilentOS. The operating system essentially "closes all backdoors" usually found open on major mobile operating systems. Some major features of SilentOS are anonymous search, privacy-enabled bundled apps, smart disabling of Wi-Fi except trusted hotspots, more control in app permissions, and private communication. Geeksphone also claims the telephone will receive frequent secure updates from Blackphone directly.
It supports the following 2G, 3G, and 4G bands, respectively:
LTE Cat. 4 is under development.
In early 2015, Geeksphone sold its part of SGP Technologies to Silent Circle to focus on wearables sold under the brand Geeksme.
14 engineers from Geeksphone, including Javier Agüera, remained in SGP.
In the summer of 2015, Silent Circle announced that they would be releasing a successor to the Blackphone, the Blackphone 2, in September 2015. It has a 5.5-inches full HD screen with Gorilla glass, and a faster Qualcomm Snapdragon Octa-Core Processor. The price also has been increased to US$799.00. Blackphone 2 does not have a removable battery.

Services bundled

Kismet Smart Wi-Fi Manager comes pre-installed. It also includes an international power adapter kit and a headset.

Reception

praised that the Blackphone's Security Center in PrivatOS gives control over app permissions, such as the bundled Silent Phone and Silent Text services that anonymise and encrypt communications so no one can eavesdrop on voice, video, and text calls. They also praised the Disconnect VPN and Search that keeps web trackers from the telephone and anonymises web searches and Internet traffic. The Ars Technica reviewer did not like that the telephone’s performance is mediocre, noting that using a custom OS means no Google Play or any of the other benefits of the Google ecosystem, spotty support for sideloaded apps, and reliance on Amazon or other third-party app stores.
The telephone's original launch quantity is unknown, but was reported to have sold out shortly after the launch began. Since then, Blackphone has resumed normal sales.
, a Blackphone was on exhibit at the Victoria and Albert Museum and one had been added to the collection of the International Spy Museum.

Financial difficulties

In 2016, Silent Circle had significant financial problems, caused by a significant overestimate of how many phones they could sell. This led to the near bankruptcy of the company.
