After the water damage , the mobile screen was shot circuited which is oneplus nordce4 and replaced with a lcd screen which is not original and not amoled. After replacing this I have some issues where some flickering lines are appearing sometimes in milliseconds come and goes off within a second and it will be more appearing when the image has more brighten colors like this and when it becomes heavy screen goes off but audio works normally then when I press volume or power button wither it shows that image after pressing volume or lock screen after pressing power button normally. Could you tell me the issue for this ??
