If you plan on buying a Samsung Galaxy S6 or Galaxy S6 Edge from one of the four major carriers in the United States you should be prepared to have a feature or two missing. It seems that all four are removing something although some are worse than others and in some cases you can install the missing apps manually. This is nothing new for US carriers in the past although this time there is a pretty good list of what you might be missing for each carrier.
Verizon’s changes to the Galaxy S6 and S6 Edge
Verizon has removed the Smart Manager and all Microsoft apps that are generally pre-loaded on the Galaxy S6. While Verizon did not say why they removed the Microsoft apps from their devices they do allow you to go to the Play Store and download them manually.
AT&T’s changes to the Galaxy S6 and S6 Edge
AT&T has removed the Download Booster, Simple Sharing features, Smart Manager, and all of the Microsoft pre-loaded apps from their version of the GS6.
Sprint’s changes to the Galaxy S6 and S6 Edge
Sprint has removed the Download Booster and changed the default for the Wi-Fi calling feature to be off. This said you can turn it back on in the devices settings if you want it. Sprint did however decide to keep the Microsoft apps to allow users to get the free 100GB of OneDrive storage.
T-Mobile changes to the Galaxy S6 and S6 Edge
T-Mobile left the features and apps pre-loaded that the others have been removing although they have blocked the ability to remove S-Finder and Quick Connect from the GS6 drop down menu. You also do not have the ability to disable capacitive lights on the T-Mobile version of the GS6.
If you do not have the MS Office apps and want them you can manually download them from the Play Store although in the case of carriers removing Smart Manager you cannot as there is no app on the market for it to date. Smart Manager is actually and nice features that allows users to manage battery and storage use on the device and is sad to see go on some carriers.
All this said my recommendation is going with an international version of the Galaxy S6 or Galaxy S6 Edge and activating it on whatever network you use to avoid a hindered experience. The Galaxy S6 is a very nice device and either way will be hacked, rooted and modded big time over the next several months so you will likely see some additions of the removed features if your willing to root and flash.
