========================================
So i just noticed something weird on my screen. Everytime there's some bright static color stayed for 5 second, and then i immediately change the screen into dark grey static image, there'll be a image retention that happen for like 4-5 second and then disappeared. Is this a type of burn in or it's just a normal or characteristics of amoled screen ?
If you guys want to check it, the link is in the image down here.
But just try it for 5-10 second.
Thank you

Didn't happen on mine. Tried it with 30% brightness for 10 mins.
Yeah it doesn't visible at lower Brightness. How about 60%-100% brightness ?
Any mods here to check this thing on individual devices ? @Anders_ASUS @Gustav_ASUS
Thank you
@Ogghy This looks like temporary image retention, which can happen with OLED. It's not the same thing as burn-in and you shouldn't be worried.
Ahh i see.. thank you for replying.
And im still wondering if it's a defect or just a normal behavior of oled (which is it's happen on every oled phone)
@Ogghy It's a characteristic of OLED displays. Check this CNET article out for more information on the subject:

It was happened to me with my old Xiaomi phone which is used to stay for several hours.
