Hi, Like everyone here, I have the same story for my iPhone XR. Although the flickering of my phone is not that worts, still it happens randomly after hours or days for a couple of seconds. It’s so annoying and I am worried if it gets worst. I contacted the Apple authorized repair Centre in Pakistan and they told me that this might be due to a drop (which is not the case for sure). They suggested that either one of the screen cable is loose or the phone needs a complete replace of the screen. As I am out of warranty, they asked 2500 PKR for the cable fix and 56,200 for the screen replacement. The second one is more than 50% of the actual price of the phone. For now, I am observing my phone without any intentions to repair it until. If anyone has a better solution than this, plz reply.
