[Sprint  Galaxy Note 4 Android Development] tx_dbs_tx:
I try my best to make sure my base roms are perfect before I move forward with mods, etc for obvious reasons. I want everybody to have the best experience possible and I want my roms to live up to what the description states. Now that I have a soild bug-free rom base I can move forward with mods etc and not have to backtrack to fix issues. It may be a slower process but it's a better outcome in the end.

As for installing S6 apps, here's the important things you need to pay attention to. (I'm saying this without ever having looked at any S6 apps). The apk file names may may not be the same as our Sprint Note 4 apps apk's so if the app is a completely different app then it's most likely safe to use as is. If the app is the same app as what the note 4 uses then compare the names of the S6 app with the Note 4 app so you can identify exactly which app on the Note 4 is the app that you will have to remove before replacing it with the S6 ap. Obviously you don't want to rename the S6 app but the important thing is to make sure you're not installing two versions of the same app even if the file names are different. Just pay attention to that first. If the app is a completely new app that the Note 4 does not have then it's safe to install it as is.

When installing S6 apps you need to first know if the app you have "sourced" has been modified to be "user installable" or if it is simply a stock deodexed apk that must be "pushed" to the device manually.... meaning you can't simply tap on the apk and it will install like any other user app. A lot of Google and Samsung apps have library files that are required before tha app will work at all... without these libraries the app simply will NOT work. The good news about libraries is that Google/Android has finally gotten smart with Lollipop and reorganized the app libraries into each apps own folder... making it very easy to locate these library dependencies. So make sure the person who pulled these S6 apps also included the libraries if the app does in fact have any. The next thing you need to know is that stock odexed S6 apps will most likely not work due to the differences in the frameworks. Lollipop deodexing requires the correct framework, boot.oat, etc from the actual device the apk/jar file will be used in so most likely any odexed non Note 4 apk's/jar's will be a big problem. That's is you take stock odexed apps along with their corresponding odex & art files and manually put them in their correct locations on your Note 4. With this said, almost always the new device apps will already be deodexed if uploaded and shared by a dev , themer, etc. Rarely do you find user uploaded "new" device apps which are odexed. So you will most likely be dealing with deodexed apk's. You can test these apps but being that the frameworks are completely different there very well could be problems running the apps. You'll just have to try them out. Most of the time they will need to be ported to some extent before being completely compatible. Just make sure you have backups saved on your phone somewhere before you start trying out S6 apps so you can swap them back to stock when they don't work.
