How to fix my Iphone's glitchy screen?

Recently, like 20 minutes ago, my iphone screen began glitching out. Changing colors, and making the phone unreadable. I've turned it off and will leave it for a couple of hours. After googling it, I found that most people fix it by restoring their phone but i don't want to do that. Is there another way to fix it?

How much data have I used on my iPhone? - 1

I currently have AT&T, and when I type *DATA#, it says I have used 108.55 of 1024. Does that mean I've used 108%(so I went over?) or does it mean I've used about 10% of 1024. It makes a big difference and I'm confused

Looks At Me Because She Finds Me? - 2

Attractive? Last week she Looked Away Quicky When I Turned in her direction in class. Could she just have drifted off? Also my iPhone has a very unique case and was on the table and she was sitting behind so she could have been looking at that.

She is a very attractive girl and I wouldn't say I'm that attractive. I think I saw her looking at me in the corner of my eye today once.

Changing the date/time a picture was taken on iPhone 5?

Not too long ago, I updated to iOS8 and ever since then, the pictures on my camera roll or "recently added" got all switched around and everything is backwards/in the wrong places. For example, photos I just took before I updated to iOS8 are at the very beginning of the "recently added" album on my phone, and photos I've taken 2 years ago are showing up at the end of the "recently added" album on my phone. It's also very random with some photos, there's no specific order they got switched to. What I'm wondering is, is there a way to change the dates of the photos I've taken in the "recently added" album so I can re-organize them so they're all in the right order again?

IPhone 6, IOS8 find my iPhone features, how to disable?

IPhone 6, IOS8 "find my "iPhone" features, how to disable?

Added (1). The new iPhone has a feature. When using the "Find my iPhone" app, it now sends a message to the phone saying "your iPhone was found at 11:40 a.m. On 10/16" or whenever it is you tried to "find" it. I would like to know how to disable this feature because if I lose the phone or it's stolen, I don't want the thief to know I'm trying to locate it! They might turn it off or something. How can I disable this automated message? How can I make it where I "find" my phone but no message is sent?
