Anyone notice that the Lumia 635's screen has temporary burn-in/image retention issues? I first noticed it yesterday after running the Speedtest.net app for a few minutes. Afterward, I opened another app, and saw the text and speedometer from the app still ghost imaged on the screen. I was concerned for a while thinking my month-old phone already had a burnt-in screen, but I noticed that after a few minutes the ghosted image was gone. I am concerned, however, about the long term effects of some on-screen elements having permanent burn-in, like the on-screen buttons or Start screen tiles, for example.
Here is the Speedtest.net app burnt-in to my screen: http://i.imgur.com/0BAOPuN.jpg
