Left side of my iphone 4 screen isn't working?

Nothing on the left side can be pressed! I did a hard reset (pressing the home and off button) but it didn't work. Then i completely reset it, but there's no difference. I don't have an apple store where i live, how can i fix my phone?
Btw, i can still do the *slide to unlock* which is odd, considering that that requires use of the screen's left side

If you scratch off the little apple symbol and glue on a robot waving at you, your phone will suddenly cease to have problems.

Sounds like you damaged the sensors on that side, so no software fixes can fix that, assuming that is what it is.
Head to the apple website, and find an apple authorised repairer in your area who can have a look.

  • Spinning Circle on the Upper Left Hand Side of my Iphone? I plugged my iPhone into a my computer and now there's a small spinning circle beside my Wi-Fi symbol. Almost as if it's syncing something. Any idea what's happening?
  • My left eye hurts when I move it from side to side and up and down? I was on my iPhone last night at 11:00 pm, and I was reading a small print book for class today. When I move my left eye left and right and side to side to look at something, they hurt. I have pretty bad eyesight, an wear thick-ish classes. Is this because I was straining them or?
  • My Iphone earphones work fine on the left side but on the right it's low? You see I thought the right side is just low but actually I figured out the sound is coming out of the horizontal back opening on the headphone. When I put it in my ear from that hole the sound is very good so is there anyway I can like transfer it back to the vertical part( the part where it ususally goes in)?
  • My iPhone 6S has varied colored vertical lines on the left side of the screen? My phone has been cracked for a bit at this point, but it had been working completely fine up until today. I turned on my phone to see these vertical colored lines leaning towards the left side of the screen and taking up around 2/3 of it. The right side is working perfectly fine. Also, when I use the phone, it clicks random apps without me clicking on them. I tried to hard reset, and nothing worked. How do I fix this?
