Any other people with an iPhone 5S and 9.02? Is yours slow and glitchy or is it just my phone?

I got my iPhone 5S in January and it's been great since then. When iOS 9 came out I updated it and let me tell you that was AWFUL. My phone was unbelievably slow, I almost wanted to get a new one. Now I've had the newest update for a few days and it's a lot better but my phone is still laggy and glitch. The biggest problem is slow internet, slow start up, and when I get a notification message and try to type, the keyboard disappears. Does anyone else have these problems or is it my particular phone?

IPhone broke-weird smell coming from it?

My phone broke, the screen is completely shattered and the bottom piece is detached from the top part on one side. There's a weird chemically-burnt smell coming from it, but no liquid coming from it. What could this be?

Do I have to sign for FedEx?

I recently got an email that said my iPhone 6s will come tomorrow. I will be at work when it will be delivered, so I was wondering if I have to sign or if they will just drop it off. With it being expensive, I'm not quite sure what they do about that. Any ideas?

Which Iphone bends the least (6 or 6 plus) bend the least?

I was thinking of getting the 6 or 6 plus but I was wondering what bends the least? I do put my phone in my pocket sometime especially when I'm walking but sometime when I sit down it's in my pocket.

Added (1). Note: I will get a case but which one bends the least?

Added (2). Note: And I will put it in my front pocket for whatever pants/shorts I wear.

Why won't the back camera work?

I have an iPhone 5c. It momentarily landed in a small puddle of water, and I pulled it out within seconds. Ever since, my phone will not take any photos from the back camera lens. When I switch to it, it displays a warning sign in the top left corner and whatever was in front of it when it was switched. This is the only damage it appears to be inflicted with. Will I need to go get fixed somewhere? And if so, how much will it cost? I'm going to travel this summer, and I want to take pictures.

I dropped my iPhone in water, now the home button is spazzing out?

So I dropped my iPhone in water a while ago and I set it dry out/dried it out. The phone still turns on and everything works fine BUT the voice control keeps popping up. I'm assuming water got to the circuit that controls the home button, so now it will randomly close out of apps, start playing music, etc. It's extremely inconvenient and embarrassing when it happens in quiet/public. I have spent many hours looking online for a solution, and I can't find one. I have enabled the guided access feature so that I have a touch screen home button, but I can't find a way to disable the physical home button or to disable voice control all together (I've already disabled Siri). Please help! I use my phone for filming videos/vlogging and I can't afford a new one right now.
