6 gig ram makes almost no differance, it is all about that most people are thinking more ram is bet ...
The main difference between the iPhone and Android phones is the optimisation, that's why an iPhone is faster using less RAM. The number of GB of RAM is important, but so is the frequency of RAM, if it is a faster ROM and so on.
For S2, they will not update to 7.0 if the phone comes with Android 6. (They said this yesterday through the youtube channel on a livestream). It will have security and bugfix updates, but just this.
The second batch of S2 will come with UMI OS 7.0 and they said nothing about android 8.
The S2 Pro will be shipped with UMI OS 7.0 and no word about update to Android 8.
