edit: it's hardware related.
Hello everyone. I got my lumia 920 about one month ago. Three days ago, i pressed to my lock-screen button and realized that the colors were mixed into each other. As i continued to use my phone, the fps dropped lower and lower. Then it suddenly froze. I had to soft reset it to make it work again. Since that time my phone freezes 5-6 times a day. The color mixing starts completely randomly and if i lock it's screen back before it freezes, sometimes, colors get back into the normal before the next time.
Here you can see the pictures of this issue. The first one shows what i mean by "color mixing". The other one is screenshot of my phone while color mixing continues. But as you can see there is no sign of problem.
So what's the matter with my phone? Can i fix this myself? Or the time has come to visit the service?
Thank you.
