Aye I updated mine to oreo when it 1st came out last week, no problems running OK, seems a little faster to me but there aint alot of difference one thing I noticed is the notifications feature now where you can put yr finger on a badge with them number (say the messages badge with a 1 in it ) hold yr finger and a pop up appears showing you who the message is from and you can swipe it from there without opening the apk. Also the clock on the always on screen is supposed to be able to go landscape mode but I aint done that yet, few extra things in settings also that I havent investigated yet. Its over a gig in size
