Katika ulimwengu wa programu wasiokuwa waaminifu na kufuatilia tech kampuni, Blackphone 2 ahadi ya kusaidia kutunza maelezo yako binafsi binafsi bila kupata katika njia yako.
toleo la pili la Blackphone na usalama na faragha kampuni kimya Circle ni hatua ya juu katika usability na ni ya kushangaza rahisi kuanzisha na kutumia, hata kwa novices faragha.
Hakuna kitu unhackable, bila shaka, na kupima jinsi resilient ilikuwa ni mashambulizi ilikuwa haiwezekani katika hatua hii.
Blackphone 2 style monolithic suti madhumuni yake. Kutoka nje inaonekana kama vizuri kuweka-pamoja generic nyeusi slab. Mbele na nyuma ni kioo, pande rounded plastiki.
hint tu kwamba si baadhi tu ya kifaa generic ni ndogo vigumu kuonekana kimya Circle alama juu ya nyuma kwa maneno "Blackphone" na "binafsi kwa kubuni" katika kijivu-on-nyeusi lettering.
Ni vizuri kabisa kushikilia, na si kama slippery kama smartphones nyingine kioo, lakini inaongea alama za vidole kama sumaku. 5.5in 1080p LCD screen ni sababu mkali na wazi. Ni ya ubora sawa na kutumika katika OnePlus 2, kwa mfano, lakini si kabisa sambamba na kwamba zimefungwa Nexus 6P au Galaxy S6 Edge +.
simu ni 7.9mm nene, ambayo ni kuhusu wastani kwa ajili ya smartphones ya leo na anahisi vizuri kujengwa. Ni flexes kidogo chini ya shinikizo kutoka mikono yako, ambayo ina maana pengine ni bora si kwa kuiweka katika mfuko nyuma na kukaa chini.

betri siku ya
Blackphone 2 ina Qualcomm Snapdragon katikati ya mbalimbali 615 processor, ambayo ni hakika nguvu ya kutosha kwa ajili ya watazamaji simu ya lililokusudiwa. Ni alijisikia snappy, zipo bure na kilichotafunwa kupitia multitasking bila suala.
Ni wale tu kujaribu kucheza graphically michezo mahututi inaweza mapambano, lakini kama kwamba ni nini wewe ni baada ya mimi nina uhakika kwa nini wewe ni kuzingatia Blackphone.
Nimeona kwamba mapokezi Wi-Fi haikuwa nzuri kama wangeweza, compared to similar devices, but 4G reception was excellent, as was call quality.
The smartphone lasted just under 24 hours per charge, with reasonably heavy use and lots of push emails and notifications. You will need to charge it once a day, but it should see you till you get home even if you go out for the night.
Kwa ujumla, you don’t feel like you’ve compromised anything in the name of buying a “secure” phone.
Lollipop on the surface
Beyond the interesting boot animation, it looks and behaves like stock Android. You have access to all the Google apps and to the Play Store to download third-party apps with no real restrictions.
The only additions really visible to the untrained eye are a Security Center icon, the Silent Store and Silent Phone apps, which is a good thing as anyone who is familiar with Android will be right at home.
The stock Android-apparence masks the hidden layers of security and privacy built into the phone.
The Security Center app walks the user through it, but essentially you have granular control over not only the personal data that apps can access, but also the hardware and services provided by the phone.
Don’t want an app having access to location data or the internet? No problem. It operates in a similar manner to the new permissions system implemented by Google in Marshmallow and made famous by Cyanogen OS.
The per-app control is only one level. Blackphone 2 has what it calls “spaces”. Each space is like a separate user profile within which restrictions can be made on a system level. Each space cannot talk to another, ensuring what you put in it stays in it. You can have, kwa mfano, a space for your work email, contacts, calendar and documents that is fenced off from the other parts of the phone.
If you want to use an app but you think it might be risky, you can put it in a locked down space so that if it does try and do terrible things it’s isolated from the rest of your data.
Getting to each space is simple. You can either switch spaces straight from the lockscreen with different codes or use the switcher in the notification shade. The level of security you give each space can be changed, including the ability to lockdown every other space when one particular one is active.
Companies can define a space and govern rules about it, which means you can blend personal and work on the same phone without compromising data security. Several other devices, including BlackBerrys can do something similar.
As easy or as difficult to use as you chose
Every setting and configuration sounds complicated, but the Security Center can guide users through it. With enough patience you can work everything out within 30 dakika.
It means that you can make the phone as easy or as difficult to use as your security requirements warrant. You can randomise the pin pad on the lockscreen, which makes it much harder for someone to snoop over your shoulder at you passcode, but also makes it harder to unlock the phone.
Other things worth noting are automatic switching on or off of Wi-Fi based on location, the promise of rapid updates to the operating system directly from Silent Circle to make sure security bugs are patched as quickly as possible, and device encryption that is on by default.
Silent Phone and Store
In additions to the modifications behind the scenes made to Android, Silent Circle offers encrypted voice calling and messaging through its Silent Phone app.
It encrypts phone calls and messages only between Silent Phone users, but Silent Phone is available on both iOS and Android, which means it’s not just Blackphone users you can call.
It requires a subscription on-top of your mobile phone contract, but will typically be bundled with a purchase of the Blackphone. Given the number of Silent Phone users is small, it’s of limited utility in general life, but if a business or group was to buy wholesale into the Blackphone they could chat without fear of being snooped on.
You can call non-Silent Phone users, which secures the phone call until it needs to connect to a traditional phone network, which is not as secure but allows users to avoid being snooped from the point of the call, if for instance you were calling across an insecure internet connection.
The Silent Store also offers apps that have been vetted by Silent Circle to be snooping free. The small selection of apps include Firefox, Keeper, Orbot: Proxy with Tor and Ghostery Privacy Browser, all downloadable with Silent Circle’s seal of approval.
The 13-megapixel camera is nothing to shout about. It produces average photos in good lighting, but washed out, dull images when shooting indoors under artificial light.
The five-megapixel front-facing camera is fixed focus and equally anaemic.
Blackphone 2 is available for £659 without a mobile phone contract in the UK, but including 100 minutes of Silent Phone subscription for a year.
kwa kulinganisha, BlackBerry’s Priv Android phone costs £559 and offers similar work-private life segregation.
Blackphone 2 promises to be the most secure Android smartphone available.
Siyo juu zaidi, kamera yake ni dhaifu na mpango wake ni badala wazi, lakini ni ajabu tu jinsi useable programu yake na huduma ni. Blackphone 2 anaendelea bests bits ya Android na haina kupata katika njia yako kama mengi ya huduma faragha-ari kufanya.
You can make your life as easy or as difficult as you want, with varying levels of security. While the Blackphone 2 isn’t the answer to everyone’s prayers, for the paranoid or important amongst us, it might be the least painful tool for the job.
