Dead pixel on LCD.
I currently have a Iphone 11 that was given to me by my mom last January. I replaced the battery because it was already worn out. Last week, out of nowhere a deadpixel like line just appeared on my screen just above the mute switch button. The line runs from mute switch button up to the power button. What's frustrating is because I actually love the device and don't want to buy or spend too much money for the repair. Do you guys have any suggestions? Check the photo for context
