When my phone fell it cracked at the top and now when I turn on my phone I have a black spot on top of the corner and it’s not totally black but it has other colors it just doesn’t really show and my phone also has lines that are blue like pixels. Android phone Sharp Crystal AquosPhone
The LCD in your display has been damaged. It likely has a crack in the LCD which can cause the dark spot and also the various lines of color . It may get worse in time so the only way to get the display fixed is to replace the LCD in the display, or for an easier repair replace the whole display (LCD/digitizer). If the outer glass on your screen that you physically touch has been cracked too then I recommend replacing the whole display.
Ok…. look. I am working on a PhD in Robotics and hold an MS in electrical engineering. These spots will go away, but only after many on/off + rgb + bl cycles UNLESS the screen is cracked. Electrons displace themselves from each other. At some point, something got squished. My advice, use your device SPARINGLY but DO USE IT. Turn on the display at least once a day, no more than a dozen, for a few weeks. If the spots are growing, you may have a seal problem preventing the screen aligning itself. If they are EXACTLY the same. New screen bezel, sorry. Finally, NEVER …. never never EVER let the device completely discharge. Connecting power after that is kind of kicking the problem in the teeth.
