white lines

so i have an iphone se and on the left side of the screen about a 1/5 of the screen theres 4 thin white lines. when i press hard on my phone screen in a certain spot that makes a weird click sound (its not loud) the lines faint sometimes but sometimes it does nothing. i did have the same problem a while ago and the way i would fix it is wipe my camera and i think the pressure fixed it. well anyway past the left of the white lines i cant press anything so i cant press w q a shift or numbers on my keyboard and on my games i cant do much which as you can tell is super frustrating
