Last week I returned an iPhone-8-Plus and ordered the new X just because the "supposed" better display and more compact design; easier to carry and brighter to shoot photos and videos on sunny days. Now I learn about the " Minor Screen Burn-In and Shifts in Colour" of the new OLED display. I have these concerns, but did not find an answer yet: How soon a Screen Burn-In will show when using the X at normal brightness levels and only increasing it when shooting Photos and Videos on sunny days? Is this going to happen no matter what, or only with continuous use at high levels of brightness, such as playing games or watching movies? I believe this is the most important aspect of the Screen Burn-In issue, so it will be very helpful to hear experiences from those that already have the X. Thanks.
