Downgrade oreo on s8??

[doglvrof2]

oreo updated on brand new S8 4 days ago. Since then: battery draining much quicker, smart lock not working and unable to personalize my text tones. These all were good on nougat.

Can I downgrade?

If so, how?

So far not impressed with oreo.

Thanks

This happens every update. Without rooting there's no going back

Try wiping the cache partition first. Here's a link. No data loss and a good idea after an update.

If that doesn't work to your satisfaction try a hard reset. That will completely wipe the phone and you will be starting fresh, like a new device. Make sure you backup your stuff prior to the reset.

You can also download the latest nougat firmware and flash it with Odin. You'll miss out on further security updates though.

I also want to revert back to Nougat. Using your suggestion. Do I need to be rooted?

No you don't need to be rooted.
