Iphone 4s siri and notifications issue? Maybe a problem with one of my processors??

Question

Okay, so let me try to lay this out. Bottom line is, I am pretty sure it's an issue with something in my phone, but it isn't consistant enough to show to someone at the apple store, I've already tried haha.
So it's a relativly new phone, I got it late June of this year, 32 GB black (if those matter for anything) 4s. Before we continue, YES, I am exiting all my apps fully, quite often (nearly every hour or two). And I restart my phone every 3 or 4 days, I sync it with i-tunes pretty regularly, etc.
Some of the issues I'm having
1. Notifications
     When I get notifications (almost always texts, and I think I may have figgured this one out but it's ****** if I'm right) and I swipe THE NOTIFICATION in my lock screen, to open the message thread or call someone back, it will swipe, but it's like I only swipe it halfway, even when it show it being swiped all the way, and it just flys back to the left and doesn't react (doesn't go to the message). i'll swipe a few times and sometimes it will finally work. As it's gone on (for 2 months or so now) it's gotten so that it drops the message halfway throgh, even though I'm sure I didn't let go of the screen. I thought maybe my touch overlay there might be going bad or somehting but it happens all over the screen (top, middle, bottom, etc) when the notification is in a different location because of how many notifications i have.
     It doesn't seem to be related to the amount of notifications I have, or how long I've had them, or battery life, etc.
     It does seem to happen most with my girlfriends texts, I'd imagine the only corolation here is either that she texts me more often so just overall I do it more often to her, or that our text thread is really long. But it still happens even with short threads, or when there are no previous messages from that person. Just an idea.
2. Siri.
     I'll give siri a command. Very simple commands, and very complex alike, she (well i changed it to he, but it happens on both) won't react. "Call Laura" and the little circle orbiting the microphone will just spin. and spin. and spin. No "I didn't catch that" or "calling laura" or "calling craig". Just spinning. I hit the home button, try again, same story. Close all my apps. Same story. It used to be that I could re-start my phone and that would help, but even that doesn't work probably 80% of the time anymore.
Both of these problems happened in both IOS 5 and 6... So I'm lead to believe it's some sort of hardware problem. The reason I'm guessing processor is simply because I feel like my phone is not a LOT slower than other 4s', but noticably slower, It doesn't just react, it takes a second.
Also, this happened for the first time today, but with my Iphone luck i feel like it might happen again, I had something opened and needed to get to my home screen, so obviously I pushed the home button, nothing happened instantly, so I waited a second or so, nothing still so I pushed home again and the popup for open apps came up. So OBVIOUSLY it registered my first home button push, if it counded the second as a second push, but I am sure I waited long enough for it to have gone home after the first push. I pushed home for a third time, the menu went away and my home screen came up. No other crazy stuff going on.
and finaly, the reason I was prompted to finaly ask this. Back to the notification thing, I had a text (not my girlfriend so like i said, this happens with all texts). Swiped the notification over, phone shuts off. Not imedatly, it shows the apple surounded by black. then it turned itsself back on.
I love apple products, simply because they are simple and work. Androids always seem to slow down, they freeze up with age, etc. But this is very un-apple product-like. And I'm sure there's some fix for it.
