IPhone 5 opening apps and typing?

About a week ago, I got a screen replacement for my phone. Everything worked perfectly fine. Maybe 3 days after getting the new screen, I updated to iOS 7. 2 days ago, on Instagram, I was trying to type a comment, and my phone started typing on its own; ntjzkksllsbbauwkxnnzzzzndnnssowl
As soon as I locked my phone and unlocked it, I had no problems.
Today, I pressed the home key, and it opened kik. So I closed kik. It reopened. This happened maybe 5 time. So I locked my phone, unlocked it, and everything was fine.
Can't quite figure out if this would be because of the screen change, or the software?
Again I had no problems with the screen until I updated my phone to iOS 7, 3 days later.

Network list is not showing up Windows 8?

I have been having a bit a trouble with my internet. (I'm connected via Ethernet)
I have windows 8 Dell Inspiron and my iPhone is connected wirelessly through my Netgear router fine. I checked all my drivers and they say it is all up to date. And for some reason when I click on the network connections list nothing shows up not even my neighbors connections is showing up. My wireless connection is not showing up either. All that's showing up is my Ethernet.
What is going on please help

IPhone broke, can I use another smartphone with my sim?

I dropped my phone… And the screen started to 'diminish' aka I can't see anything on my screen, however the phone is fully functional.
I was wondering, will it work if I insert my simcard (its a microsd card?) into another smartphone? Or does it even have to be a smartphone?

How to update ios 7 to iphone 4?

What are the steps to updating my iphone 4 to ios7?

i have an iphone 4 and i want to update it to ios7 but a couple of things are stopping me:

1.) i did not get the last update so i don't know if that has something to do with it
2.) i'm kinda afraid to update ios because last time i updated it, i lost all my pictures and contacts and i don't want that to happen again. I do have icloud set up but i really don't know how that works.
3.) also it says i have (1) software update but when i go to it i get this message saying "unable to check for update. An error occurred while checking for update. Cancel Try Again." and when i tap "Try Again" it gives me the same thing.
4.) i have no storage left. 0bytes and my 6.4 GB is used. And it says my icloud is almost full. I don't have a lot of apps just way too many photos. I'm willing to dump them all on my laptop or a CD or a flashdrive or something but i don't know how.
5.) Also i can't send or receive text messages. Whenever i try and send one its gets stuck at the sending bubble. Everything is on except my VPN and i'm not sure what that is.

so as you can tell, i'm not very tech savy lol. I doubt anyone will actually read through all that and know what to do but i'm just putting it out there just in case. If nothing works ill just go to the apple store this weekend and tell them.

Does T-mobile make you get a data plan if you pay full price upfront for an iphone?

Say if I buy the full price of the new iphone upfront, will they make me get a data plan? I heard AT&T does but T-mobile doesn't. Also is there anyway to put a sim card from a dumphone into the iphone? And also, I heard there were pre-paid plans that have unlimited text, calls, and web for only $20 a month there. How does that work? All suggestions appreciated, please help.
