update to oreo

[LSerafim]

Hi.
I changed my s5 neo for a new a8 2018 and received an update notice for android 8.0.
However I had a bad experience with an official update in my old s5, a lot of applications samsung and significant reduction in battery.
I want to know if the A8 2018 has the same problem after the android 8.0 update.

S5 is over a 4 year old phone, obviously it can't keep up with latest updates. A8 is a new phone, so it can keep up and no problem will occur.

Not necessarily true. Old phones can get new updates just fine. The S5 has custom ROMs for Android Oreo and they work.

Some S7 and S8 owners complained here about battery drain after Oreo. Sometimes it's because of apps that aren't up to date with the Android SDK. Some other times a simple cache cleaning does the trick. Some other other times a factory reset is needed. All this is independently of the device.

My S7 is as "old" as this person's S5 Neo was when it last received an OS update (Android 7.1.1 in August 2017).

The last samsung update to s5 neo in canada is 7.1. I don't understand one official update with lots of bugs and performance drop.

S5 neo has like 2G ram, 1.6ghz very old Exynos. So there's a really high chance it can't keep up with latest updates.
A8,S7 they're like double the specs of S5 neo. It's a huge possibility that S5 neo hardware is at fault.

Yeah, the update has proven to be beneficial thus far and most devices.

I'd recommend after updating your device to simply Wipe your Cache partition through the recovery mode after doing the update. That usually solves a lot of update issues. It wont clear any personal data so no worries there.

follow that link there and when you get to recovery mode just select wipe cache partition and then reboot

There is no wipe cache partition mode listed on my s7

Too late to my s5.
I don't want problems with my A8.
Thanks to reply, but i don't have warranty if will work fine like before the update, all tips blame third app or user configs.
I don't have any warranty or method "official samsumg" to revert the android update.
To easy reply:
I will have troubles or performace drops with this update for A8 2018?
