IOS 7 has made my iPhone 4s not work properly?

For starters, the play button on the slide up bar doesn't work, but every time I put my phone on charge it says it is 84%, all the time, it never changes. However, the main is; it turns off for no reasons, every couple of minutes. The screen goes a little fuzzy, then it goes black and the apple symbol appears. It is really starting to annoy me, and none of this happened when I had IOS 6. I also had a lot of problems trying to download IOS 7, (error 29). If someone can help, it would be much appreciated, thank you.

I find iPhones can be hard to figure out when a problem occurs, so if I was you I'd speak to Apple on the phone or get an appointment at the store and they will without a doubt fix whatever problems your having with your phone, don't play around with your phone or get the old software back by installing it off a website because it will no longer be an apple product and they won't touch it

  • Why doesn't siri on iphone 4 work properly? I downloaded Siri using cydia. She works, and do simple tasks like set an alarm, set a timer, or send a text, But when i ask her to search for places near me her answer is always sorry i can't find games for such and such. Her answers are almost always irrelevant to my question. There was an option to buy Siri for 99 cents that uses google, and seems more legit than the free downloaded. Can anyone help answer my question as to why Siri is acting "stupid"?
  • What's the difference between a international made iPhone and US made iPhone? I plan on buying or trading my iPhone 4 for a new iPhone 5C on Craigslist or at my local phone shop. Plus, can I flash a unlocked iPhone on to any carrier like PageOne or revol wireless?
  • My iPhone 5 speaker does not work properly? I have a similar issue and think its software related. Siri sounds very tinny in the iPhone 5 compared to 4s. Lock sounds, key sounds also much quieter but get better if you turn them off and on - hence why I think it's software prob. Same with external speaker and headphones. Please Apple release update. Call volume is great in mine, just Siri sounds terrible and low lock and key sounds.
  • My Iphone 3 won't work properly I put my iphone 3 on charge, it does it's thing charging etc, once it's finished it goes to the homescreen, sits there for about 1-2 seconds then turns off and begins to re-charge. Only very rarely it stays on for around 30 seconds - 1 minute then continues to do the cycle. I'm not sure what to do, maybe it's the battery? Any help appreciated! To all those who answered so quick and answers to come thanks so much! I'll do as you say and report the news!
