Before it's release there were rumors that the Galaxy S6 would feature less bloatware than previous devices; however, that doesn't appear to be the case. The site reports that there 56 apps preinstalled, 6 more than on the Galaxy Note 4. The apps you'll find range from Google apps to Samsung apps (S Voice, S Health) to Microsoft apps (OneDrive) to Carrier apps (T-Mobile) to third party apps (Instagram, WhatsApp).
Gizmodo notes that despite previous statements from Samsung that "Samsung has allowed users to remove the pre-installed applications on Galaxy S6 and S6 Edge" you can only 'disable' them.
This removes them from the app drawer and the homescreen, but not from the phone entirely. You're basically opting instead to put them in a sort of stasis, out of sight but not out of storage.
When asked for a statement Samsung said:
Simplicity is critical for usability and functionality, so Galaxy S6 and Galaxy S6 Edge offer a refined and optimized user experience and the offering of core and preloaded apps has been streamlined. Some apps can be uninstalled while some can be disabled, and this varies by region and carrier. Further, 40% of the features and steps have been deleted compared to previous models.
Many iPhone users have also complained that they are unable to uninstall native applications, especially with iOS 8.2 introducing an Apple Watch app that can't be used without the smartwatch. However, iOS users have far fewer apps to contend with and they're all from Apple.
The Galaxy S6 is set for release next month. How it will fair against the iPhone 6 remains to be seen. Please follow iClarified on Twitter, Facebook, Google+, or RSS for updates.
