I’ve dropped my iphone and when i picked it up it has small black area on top right corner, touch still works perfectly even where the black area is. How can i fix it? Thank you.
It appears you have damaged the LCD on your phone. This black spot will also grow in size with time. You can replace the LCD by ordering this part and following this guide.
@amarakas - you can replace the screen for a LOT less than above price. Shop around to save.
