If there is a company that is leaving as which more takes in launch updates to their ships logo, this is Samsung (an example is the of the S6). Although, if you look from another point of view, it can be an advantage, because that can mean that a Samsung phone owners have access to changes, such as is the case with the Galaxy beta program, precisely the S7 and S7 edge.
Seems, that Samsung has changed of shape silent it resolution in screen by default of the 1440 p QuadHD to them 1080 p FullHD. While this can be a tort for those users that bought this phone that wanted it greater resolution possible, seems that not has much importance to first.
Not has as much importance by a reason evident, when is makes the transition of resolution QuadHD to Full HD in a screen of 5.1 to 5.5 inches, the change is just visible by the eye human. Especially when is takes the factor of the climbing of the interface even under different resolutions. The screen resolution and scaling of the elements on the screen maintain separate and different settings.
Of all forms, Samsung has to confirm and explain the reason for this change, although the most logical explanation would be the lower consumption of resources, therefore, the battery. Less pixels means a use less of data and of the CPU. Although relation to the battery should be checked if it is true.
What is curious is that the apps still are “free” of power using the resolution QHD. Where is has reduced the resolution to Full HD is at the interface of user. Of all forms, to the be still in beta, can mean that in some moment Samsung back to the 1440 p. Not would be the first time that in a beta is make changes radical that then are deleted.
