Operating System:

Most of the smartphones are coming up with the new developments on their Android operating systems and so are the Google Nexus 6 and Samsung Galaxy Note 4. Google is improving with the release of its every device. Google Nexus 6 is expected to be based upon new version of Android i.e. Android 5 lollypop. It could also be based on Android 5 milkshake system but that depends on the completion of its manufacturing. Same is with the Galaxy Note 4. It is also rumoured to be based upon Android 4.4 or Android 5 lollypop operating system. 

Processor:

One is the smartphone and other is the Phablet. Google Nexus 6, the smartphone, is expected to have Qualcomm Snapdragon 800 or better, 3Ghz processor i.e. we can expect Google Nexus 6 to be of really high speed and efficiency. While with Samsung Galaxy Note 4, it is expected that the processor would be Exynos-6 Hex-Core Processor. For those, who are not much technical & can’t understand the technicalities, we must inform that Samsung Galaxy Note 4’s processor and processing speed will both be better, thus giving a better experience.
