OnePlus managed to garner a lot of attention with their first device, it is same with the 3rd iteration of their flagship killer.
The OnePlus 2, Despite being claimed as a Flagship Killer of 2016, the phone itself lacked in a few hardware areas which made it lose when being compared with actual flagships. It seems that OnePlus has learnt some from their past mistakes. A few of the complaints on the OnePlus 2 are seemingly being addressed with the OnePlus 3. According to new information , the OnePlus 3 is aiming to be a better affordable package than its predecessor.
A screenshot of the OnePlus 3 was posted, allegedly running a build of the N Preview on OxygenOS 3.1.0. Android 6.0 Marshmallow for OnePlus devices is based on OxygenOS 3.0.x, so a bump up in the sub-version makes sense. But since the N Preview is a “preview” for good reasons, it is unlikely that OnePlus would release the device with a developer-only Android version. Our best guess is that the device if it launches before consumer release of Android N, will ship with Android 6.0. The Android N update would then be rolled out when the version became public-ready.
A return of NFC on what will be OnePlus’s actual flagship of 2016 was also mentioned. This should silence critics who lamented the loss of NFC in 2015, and it makes good sense for flagships to bear this. Along with NFC,the existence of a 5.5″ 1080p display was also mentioned, Snapdragon 820 SoC, 64GB of internal storage and a 16MP rear camera.
