Very important to have the Samsung quality screen under sun out door in SG. Their brightness improving syrongly from model to model. Those Note 3 and older aren't good enough, Note 4 and newer are better and better and readable outdoor under SG noon sun.
LG newer models are also OK. But lag behind Samsung quality. Sony n Chinese brands also lag behind Samsung. Gay phone lacks far in not only brightness, the gays are poorer resolution and unable to make curved screen.
