^^ This. Under the right conditions any lens will flare, including Hasselblad, Leica, and even Apple, which people seem to expect more of, lol. One of the ‘right’ conditions is having a light source in the image, which there is in post #104.
Cell phone cameras are at a disadvantage because the front lens element can’t be recessed 20mm or more as they are in most conventional cameras which provides some shading for the lens. If the light source is just out of the image area, shading the lens with your hand, hat, a piece of paper/cardboard are time-honored methods to reduce flare. Also keep the lens cover clean, a dirty lens cover won’t help.
It would be interesting if they tried computational methods to reduce lens flare as it is usually undesirable in casual images. But sometimes it is used as an artistic effect, so you’d need a quick way to toggle it.
