Why does my Iphone 4 freeze after iOS7 update?

I was somewhat excited about iOS7 but now I wish I wouldn't have downloaded it because now every time I type on it it starts to freezing for like 20 seconds
how can I resolve this? Please serious questions only

Its probably bugs with the update.

I would Restore the phone.

You need to save all your content before you restore. You might be able to link the error to one app and fix it. I do not have any information to go on. I think you can post more if you need more help.

Is your iPhone experiences frequent freezes, you can't link to one application or usage error, you might try restoring it.

Warning Save content before you RESTORE iTunes will not replace all apps and personal content.

To restore your iPhone, connect it to iTunes, click its name in the left pane of the program and click "Restore" within the "Summary" tab. Click "Yes" when iTunes prompts you to back up your iPhone's content, then follow the on-screen instructions to restore your phone.

Hopefully apple will dispatch a fix update!

  • Why does my Youtube freeze so much on my iPhone when I drive? I like to listen to youtube videos when I drive, but for some reason, the videos pause. I've tried turning off Wi-Fi, but still don't know why it does this? The videos sometimes play perfectly well, it's just hit/miss. Any advice? I have an iPhone 4s and use the Youtube app.
  • Why does my iPhone 5s freeze every morning? The last few days I have turned on 5 or 6 alarms in the morning because I have trouble waking up since school started. Every time they go off, my screen freezes and jitters every time I try and turn them off or unlock my phone. If I restart it, it's fine but even that is hard to do since I can't slide the power off button due to the freezing. It's less than a year old. Does anyone know why this is happening and/or how to fix it?
  • Why does my iphone 4s freeze when i get a text? My old iphone 4s did it too so do you think its my carrier? I have sprint. It only happens when i get texts from certain people. It freezes up and then doesn't show me any of my texts from anyone. So then i restart it and they come back but then it happens again if i'm texting that person. All of my other apps work and everything but its just my texts.
