Just for those who care about their phones.
My wife and myself are addicted to this game and I have played almost 11 000 games on my phone and my wife has played almost the same amount on her phone.
We have always had both our screen's brightness on full and not auto. ( Both using Samsung Note 4's )
We have both got the comment icon burnt into the screen as well as the 2 frames of players in the top right and left corners.
Hopefully Playdemic would take the white icon and frames away and change it to a darker colour, to prevent screen burn-in.
If you want to check your phone, view anything with a white background and you might see the burnt-in effects.
Both our phones show the comment icon and outer player frames in light orange.
