AMOLED still has burn-in problem. I don't wanna see yellowed dirty screen when I entered white page. And LG's POLED is even worse. Their POLED screen has uneven color problem. And also, flickering is an important issue. That make eyes much tired. On top of that, curved edge design is weaker than flat design. Durability is one of nokia's advantage, right? I hope nokia take the right decision.
