The Samsung Galaxy Note 3 is available online and in retail stores. It's out now on all the major US wireless carriers. Nick reviewed the Note 3 for us and really likes it. The device is really big, and that's a good thing. Some users may not be excited about the extra large screen, though. If you want some of the Note 3 apps but don't want the big device size, you can load some of the stock Note 3 apps on your Galaxy S4.
Thanks to a senior member over at XDA Forums, you can load some of these apps up for yourself. LastStandingDroid from Sweden has pulled a whole slew of Note 3 apps from a system dump and posted them online at XDA. Some of the most popular Samung apps like Magazine, My Files, and the updated Camera app are available for download. KNOX is currently being worked on but isn't ready yet. It may take a little while for devs to get KNOX working properly. The total list of apps is pretty impressive, though. While some of the apps will work without an issue, some of them require Android 4.3 Jelly Bean. They may not work for every Galaxy S4 user until carriers start pushing the Android 4.3 update out to devices. You can download the 4.3 update for your GS4 if you want to get a head start on that. Some of these apps aren't optimized for the smaller screen on the GS4, either. Just keep that in mind when you're installing them on your smartphone.
If you prefer the Galaxy S4 screen size over the larger Note 3, you don't have to miss out on some of the updated Samsung apps that came with the Note 3. The KNOX app in particular is great for users who want to user their personal device at work.
We haven't tested any of these apps ourselves, so head over to the XDA Forums thread if you need assistance. LastStandingDroid is keeping things updated over there, and other Note 3 and GS4 users are pretty active in the thread. If you get any of these apps working, drop us a line in the comments and let us know how they are working for you.
