I remove old Noalox and reapply every couple of months. I don't see a need to do it more often than that.
I can't imagine a sigelei screen just popping out on it's own. Something probably encourages this to happen.
sigelei V3 and V5 use a lighted OLED display. If turned a certain way it can be impossible to read in direct sunlight. If I need to read the display outdoors in the sun I can always shade it with one hand to get a reading. I don't need to see the screen to vape. Looking through polarized sunglasses can make it impossible to see an OLED or LCD display. Tilt your your head or rotate the sigelei 45° to see it perfectly well through polarized sunglasses.
