Hi brand new to the forum. I have an iPhone 4 for about 6 months now about 4 weeks ago dropped the phone out of my truck & smashed the screen to bits. Had a new screen fitted 2 weeks ago & only in the last couple of days I have had lines going through my apps & just now the color on the screen will be normal then it will go really bright & even just go black. I can press the top button to send it to sleep then unlock it & the color is fine but not for long. It hasn't been wet only dropped the one time but does live in my shirt pocket for about 12-14 hours a day other than this problem phone is great.
I'm in Australia too if that helps.
