Why am I not receiving the notifications from texts on my iPhone?

I have an iPhone 5 and whenever my girlfriend texts me, I don't feel a vibrate, hear a ring, and when I look at my lock screen, there's nothing there, but when I open it and go to our messages, there's like five messages that I haven't gotten notified for. Is this a bug or glitch with the iPhone 5 or is there a fix for this?

Dropped iphone in the toilet

Reached into my coat pocket to get my keys, out pops my iphone and it goes right into the toilet. It was in there for probably 4 seconds. I pulled it out and immediately dried it off. I clicked the lock button and it turned on, i continued to dry it off and then it shut itself off. I put it in a bag of rice about 6 hours ago, i tried to turn it on and nothing so far, i thought the screen flickered a little but i can't be sure.isn't the headphones jack supposed to turn pink if it has sustained water damage? Mine isn't pink.i'm going to keep it in rice for the weekend but has trying to turn it on ruined it? Should i just leave it alone for 2 days?

Added (1). After 8 hours my iphone started vibrating in the bag of rice. It tried to reboot itself for about 10 minutes and kept telling me to plug it into itunes. It wouldnt let me restore it but then it started working kind of normally. The screen flickers a little and it tweaks occasionally and goes to voice control. The home button doesn't work at all but the top button does.inside the headphones jack is pink. I turned it back off and placed it back in the bag of rice. I was going to keep it in there for another 24-48 hours. If everything comes back and works normally accept the home button, can the home button be replaced? I don't want to have to get a brand new phone if i just need a new home button!

My new Iphone is not syncing to Itunes? AND I lost all my songs?

Hi! I just got an Iphone for Christmas, but before that I had an Ipod touch. The ipod was synced to my itunes. Then, I decided to put my songs on my phone too. So last night I plugged my iphone in for the first time and tried to sync but it wouldn't. In fact, it didn't even recognize the iphone at all. Then today I went back on my itunes and all my songs are gone so I'm downloading them all again right now. But how do i possibly recover my old songs and especially how to I sync my iphone to my itunes? Thanks. (Sorry I'm only 14 I don't really know this) P. S. Sorry if i put the question in a slightly wrong category haha.

Will an iphone mini macro lens work with my droid?

I really want to get one of those mini macro lenses that attach (magnetically?) onto your smartphone, but all I see are ones for iPhone and I have a Droid. Do they have any for droid phones? Will the iPhone ones still work with droid phones? It seems like it should, since it just goes over the top of the camera lens. If you know please tell me!
