One of the biggest changes likely to be seen on the Galaxy S6 is the removal of the pre-installed Samsung bloatware (or in-house Samsung apps).
As of now, there is no word which are the apps that will not be pre-installed on the next flagship model. The report speculates that S Voice, S Health, S Note or Scrapbook will not be preloaded, and instead will be offered via Galaxy Apps store.
Sammobile cites insiders to claim Samsung will preload some Microsoft apps on the Galaxy S6, a move likely to be a result of settled contract dispute over patent royalties between both the companies.
Some of the popular Microsoft Office apps likely to be preloaded on the Galaxy S6 are OneNote, OneDrive, Office Mobile (alongside Office 365 free subscription), and Skype.
"Samsung has also adopted a lot of animations and effects that debuted on Lollipop - we can already see some of these effects in motion on Lollipop on existing Samsung devices, and it looks like the visual experience will be even better on the Galaxy S6," it adds.
The report also lists some UI changes from the new TouchWiz such as a revamped default keyboard app; more theme options; colourful Samsung apps; app drawer to include 4x4, 4x5 and 5x5 icon layouts; music app to still run in full screen mode, and the dialler app is described as "green as grass."
