Just an update: called samsung today for my phone screen keeps automatically waking up on its own with the error āiris scanner could not recogniseā or something like that and had ask for an update about the wifi disconnecting issue one shot. It seems that samsung is still working on it an update and would want to rectify all mistakes done with all recent oreo devices. She couldnt give me a date by when the update is coming out but she did confirm two things that Iād like to share with you guys for there are some doubts with people commenting here.
Device affected are: S9, S9 Plus(which will receive the updates for they are priority devices). Note 8 for it is a high level device in the note series and still costs more even than the S9 series. There isnt a guarantee for the S8 and S8 plus to be fixed for they will push out the S9ās update to the S8 in hopes itāll rectify the mistake they did and yes once again the lady on the line CONFIRMED IT IS A BETA VERSION BUT OREO 8.0 ACCORDING TO HER IS A BETA STAGE ANDROID OPERATING SYSTEM. There were bugs in 8.0 in not only the samsung phones but other phones also that were only fixed in 8.1 and believe it or not if you google it other models phone with 8.0 is also facing wifi issues like several google phones. She said it isnt as though it was samsungās fault to push out a beta version when google had already tell them it was stable. She was a senior advisor and she said the least i can do is be honest with you rather than giving you false hope.
So for those in doubt, it is a beta version with bugs and its up to individual phone manufacturers to push out the update so we should thank samsung for actually working on it to push it out. But yes it is an unstable version of android and they should consider re-dealing with google or whatever on giving 8.1 or maybe theyāll push out the update of android P sometime sooner. Lets see.

She also said if the issues still persist even after the update like some google phones that will require a motherboard replacement i see that making no sense for in nougat my phone worked flawlessly. Google phones faced the bug even till 8.1 also. She said iād have to consult the service center to see if there is a downgrade option back to nougat for she isnt sure of that option when i asked. Its just sad what an update can do to such a wonderful beast of a device. Haiz. I should have never updated in the first place/url]. Regrets. My entire family upgraded 4 devices together and now weāre all stuck with the same issue

its really saddening.
