[Galaxy Note 4 General] boodies:
Lol, not sure about the "various tricks." Finger print works great. I actually use both thumbs and works great. It's very handy and much quicker to use than pin etc. I blame samsung for providing crappy instructions tho thats for sure. UV might not have use for you but there are various people some even with medical conditions that will find it handy. The Galaxy Nexus had the barometer because samsung made that model and it defintely helps in locking up the GPS. My video here. All these, "features" are something that make the experience a lot better.

Now the Software makes it 10 times better. Even little things like being able to minimize the call to a little icon automatically when you press the home button while in a call to jot down a note during the conversation. This has provided me such a relief from not only looking for something to jot down on but save the planet at the same time. When i'm in the middle of some program, lets say youtube, and I get a call. With the Note 4, I don't get a huge interruption with a call window taking up the whole screen. I get a small portion on top of the screen where I can answer, hangup etc. This is extremely convenient as I just take the call and minimize that window to keep on doing what i'm doing. Now this feature, I don't know if it's available in stock android but is extremely helpful to me as I talk to a lot of people. When I call someone, the screen tells me the last time I talked to that person along with a bit of the last message I wrote them. Really helps me out a lot in keeping track of all the people I talk to. A lot of apps im in, I can minimize them to a small window, or an icon always ready to open while i'm on another app. This seamless multitasking is just not available on other devices.

The pen tho is truly a blessing. Lets say i'm on a call. I need to write down some information or number. I take the pen out, action memo opens, I write the note or number. If it's a number, after I hang up, (while i'm still on the action memo screen) I can click a button on action note and it will highlight that number (great OCR) and I can call text etc. You might not find that useful but that thing is something I really thank samsung for providing. Now if you're in the creative field, there's no doubt the s-pens with its 2048 sensitivity (same as my intous 5) is a super convenience to have in your pocket with a drawing pad. The ability to select stuff and draw marquees with the spen etc is something non creatives might not appreciate. And it's awesome for certain games as well lol. Did you know the Note's voice recorder can record 5 or so different voices in conference mode and separate them out? I hear journalists are looking forward to this feature and I'm sure many others. Here's the deal. I need a lot of multitasking at work. Im constantly talking and looking at calendars etc. There are tons more reasons that I can talk about that helps me practically, daily. Lag? Those little stutters.. that all phones get.... are nothing compared to the benefits this phone offers. And this phone is fast dont know what youre talking about lol. Look, I'm not sure if you work for a living or not. But if you just own a phone to play games and watch movies, (which the note 4 is better at anyway lol) then it's okay I guess to use any other big screen phone. So good luck with your other phone.

ps - i'm pretty sure the note 4 will have a better display and a better camera and video recording as well :P
