My iphone has been acting up over the last few months?

Iphone 3gs! My iphone has been acting up over the last few months, when I click 'contacts' it says I have none, but I can still find them when I type their name into the search bar, and it also does the same thing for photos, and now I struggle to connect to the Wi-Fi unless i'm within 10 feet of my wireless router.

It's a 3GS. Clearly it's buggy because it's older and all older electronics will malfunction.

As for your wireless issue, your antenna in your phone sounds broken.

Go get a new phone. Just not the 5C:@

  • Why has my battery on my iphone been draining the past few days? I have a 16 gb iPhone 6 and for the past three days the battery has been going by really really fast, even when it's asleep and in my pocket. I tried deleting apps but nothing works.
  • My iPhone 6 has been acting a bit weird lately? I'll be texting a few people on imessaging or kik, and I'll have to double tap the home button. Sometimes when I double tap, it brings me to what looks like my home screen, but with no apps, just the wallpaper I have set. When I press the home button again, nothing happens. I have to restart my phone. This can happen up to 3,4, or even 5 times a day. What does this mean? Is something wrong with my iPhone? I have the newest updates installed btw.
  • My iPhone has been acting weird For the past few weeks, whenever I hit the middle button to escape an app I'm in, it often doesn't work, and I have to hit it a few times before I can get out of the app. I tried deleting some apps, to see if it would help, but even with a lot less apps on my phone, it didn't help anything. Does anyone know why this is happening and/or how I can get it working better again?
  • My iPhone 5 has been acting up a lot? Ok. So It said no network connection when I go to fb or safari when I have my Wi-Fi on. And Wi-Fi been turn off by itself. I got this phone about 1 week ago. It been pissing me off. Why this phone acting weird? It's said no network connection a lot of times. What should I do?
