This is pretty normal, actually. The biggest disadvantage with AMOLED-screen phones is that the screens degenerate before you get rid of the phone. My Turbo 2 started getting screen burn-in about 5 months after I purchased it, but I exchanged that one for a new one. The On-screen buttons on an AMOLED display only makes the problem worse; AMOLED-screen phones with capacitive keys will only get burn in at the status bar, in typical conditions. Another thing: since the AMOLED screen is primarily made of a multitude of LEDs, these LEDs are driven very hard when white is displayed on the screen, and the LEDs turn themselves off when black is displayed on the screen, so that contrast between the black bar and the white buttons causes the bar to "reverse burn", where the bar will show colors the way the entire screen did when the phone was new, the other parts of the screen will be darker and dingier than the bar (and the status bar), and the on-screen buttons will be the dingiest part of the screen. Also, by "dingy", I mean the AMOLED, over time, will take a noticeable shift to yellow, where every color will have a yellowish cast, due to the Organic Decomposition of AMOLED screens (they are made of organic material) as well as the fact that the blue subpixels are the first to decompose, because they shine the brightest. The yellow shift over time cannot be changed or reversed. The on-screen keys and bar burn in can be slowed/ counteracted by downloading an app called GMD Immersive, which allows you to put your phone in Fullscreen mode in most situations you are using it. You do have to bring up the on-screen keys when you are using the keyboard, but in most other cases when the screen will be on for extended periods of time, the on-screen keys and black bar will not burn in as quicky and this app is a good thing to use to counteract this. However, the GMD Immersive app also allows you to take the status bar out of view, as well. This is a very good app for any AMOLED-screen phone to counteract the eventual burn-in that you will receive. *Side note* I know this is unrelated to what I just said, but the belief that AMOLED screens are more efficient than LCDs is not always true. It largely depends on the content you put on the screen. An AMOLED screen will be more efficient than the LCD when colors displayed on the screen are darker/closer to black, where the AMOLED's LEDs are not driven as hard or are not turned on at all, whereas the LCD's backlight is still active when displaying dark colors/blacks (It is a good idea to surf the web in invert cors on an AMOLED-screen phone if you want to save a lot of power). An LCD display is more efficient displaying lighter colors/whites, because the AMOLED's LEDs are driven very hard when displaying whites/lighter colors, and are shining brighter and using more power to do so, whereas the LCD's backlight is working no harder to display whites than it is to display darker colors. For my usage, LCDs would be more efficient than AMOLEDs due to the fact that most content I display on-screen is usually white or a lighter color.
