d'andrea, Jan 1, 2018 : Hi everybody, here are a few notes of the first 24 hours with Oreo on my OnePlus 5. - First of all, I'm really excited about the face unlock; - Overall the phone is slower than in Nougat (examples: qwerty keyboard, transition between apps, folders opening) - The phone seems to be hot after 15 min. usage and It is burning hot in recharging with WiFi on; - The charge of the phone seems to last 24 hours only, instead it lasted more than 48 hours in Nougat; - The swipe-down-from-above curtain in the home page in Nougat conveyed much more information, even if it required 3 touches to pass from WiFi to 4G connection; - The Google icons in Nougat were bigger and clearer, even with the absence of the circle in background - There is no resuming shelf in the settings app anymore - Predefined mode: the white background of the gallery app is very tiring for the eyes, in Nougat the background was black - There are no Capital letters at the beginning of the words of the date in the blocked screen. I think this things should be fixed in the next release. Happy new year to everybody!
