I noticed something yesterday at night : when I turned off my display, the screen flickered slightly with a white color. The brightness is too low to capture it on video. I’m not sure if this is normal; I noticed it while using my phone at night even now at the time of writing this, but I can’t tell if it has been happening since day one. The display works fine otherwise, but the flickering occurs when I slightly move the phone, and the fingerprint icon appears, causing a small portion of the upper and lower areas of the screen to flicker. Is this normal? It’s making me worried about my phone’s display.
