Is one plus 2 Secure
The biggest change when it comes to the software of the OnePlus 2 is that it has now moved from Cyanogen to Oxygen (both if which are based on Android Lollipop) which is more of a "real OS". What we mean by this, is that only the kernel will be open source. This is somewhat of the disappointment, as Cyanogen was mostly open source which allowed people to create patches, fixes and could generally be checked for faults.
Many of the common privacy features have been transferred over to the Oxygen operating system, and in our opinion they are a lot easier to manage and handle. While there are reports that some more in-depth superuser settings will not be available we feel that most of these were unnecessary unless you are extremely cautious in which case you're likely to prefer using custom ROMs anyway.
The popular App permissions are back, and now you can access these even quicker from the main settings menu. This is a great feature which allows you to override the default app permission settings which will not only save some battery but also protect your privacy. Unfortunately, there is still no overall override so you will have to go through the painstaking process of doing it for every application that you use. We'd personally recommend disabling location and contacts access for most applications can do without. Unsurprisingly, Facebook apps require the most permissions by far, and we ended up disabling nearly all of them.
The most noticeable difference when it comes to locking your phone, is the addition of a fingerprint scanner. We tested ours and had no problems, but there are reports to the contrary. For the moment, we are going to stick with the classic lock mechanisms as we believe it's only a matter of time before this technology is hacked. It's already been proved to be possible in the physical sense but we're more worried about hackers stealing our biometric data.
From then on, you have your phone encryption, credential storage and some other useful security settings which can help protect your data even more.
Lastly, there is a built-in OnePlus VPN application which you can use to help secure your internet connection. This only support PPTP, L2TP and IPSec so we'd recommend installing a providers application that also allows OpenVPN.
Conclusion
On the whole the OnePlus 2 follows adequately in the footsteps of the OnePlus One. While some features that people might find useful are missing overall it's brilliant. While it is cheap and more than worth its value if you have a phone that is less than a year old, then it's probably not worthing in just yet.
