My nokia n9 was under the sun for about 10 minutes and afterwards (i don't know if the sun was the cause), the display started giving a very pinkish tint. It then alternated between a green and pink tint.
How can I solve this problem? I have rebooted the phone several times and it has been 5 hours since then.
Was it because of the heat?
Also, I noticed that I am facing a problem with my lock screen wallpaper. My wallpaper has a gradient in it and instead of showing a smooth gradient, the phone shows stripes of colours. The gradient becomes smooth again when I swipe the lock screen upwards though. I tried with many different wallpapers and the gradients still do not show up nicely. How can I solve this problem?
