Does anyone know if Team Win works for ace 4(SM-G357FZ)?

And if so, does anyone know if CyanogenMod works on the same device as above?

How to use a phone (Android and/or Windows) as an NFC-tag keychain?

Let me start by saying that I hope that I've posted this topic in the right place.

The scenario: so let's say I'd have a bunch of devices I wanted to unlock via NFC. Per device I'd have 1 tag.
The problem: but then I'd have to carry a bunch of tags around -- and god forbid if I'd happen to lose one.
The solution: what would make things much more convenient, is to use my phone as a NFC-tag keychain. I'd store the virtual tags in an app or some thing, and I'd emulate a tag through the phone when I want to unlock a device.
The questions: how and what would enable me to store multiple tags on my phone, and easily access them? And if I would select a virtual tag, could my phone then use that virtual tag to emulate a phyisical NFC tag?

I've genuinely tried to research all this, but I could just not find any clear cut answers. I guess that my sought-after-solution is either not mainstream enough, or I'm not posing the right queries to Google. Also I can't do my own testing, because my current phone does not support NFC. My near-future phone definitely will. You might ask why I am posing these questions now then? Reason is is that right now I want to building some NFC readers for locks for said devices. But before I do so, I'd have to know if my phone can indeed act as an NFC-tag keychain.

Adding functionality to the Edge - Which apps and/or Custom ROMs to use?

My S6 Edge will be delivered in the next couple days and I'm gathering some info on how to get the most functionality out of the Edge. When looking at the Note Edge, the larger edge allowed a great deal of native functionality, like the swipe out app shortcuts, and swiping down for a widget bar with wifi/flashlight/etc toggles. I'm looking to have the same or greater functionality on the S6 Edge.

Here's a couple apps I've found that look to work well with the S6 Edge:

for app shortcuts, you add this as a feed: QuickLaunch: http://forum.xda-developers.com/gala...-edge-t3090255
for app/widget shortcuts, usable anywhere without the toggle bar: SwipePad: https://play.google.com/store/apps/d...ipepad.android

Anything else recommended as a favorite addon app for functionality?

I also plan on rooting immediately. Is there any recommendation for a Custom ROM that may have additional options along these lines? Or just, in general, any recommended ROMs I should consider installing right away?

Thanks guys!
