Downgrade back to One UI 6

[chemo0208]

Does anyone know how to get me back to One UI 6 because I'm on the new One UI 7 version?

Sorry to hear you don't like 7.0 but they are no way to downgrade the OS back to 6.1

If this does not become an option or a classic UI 6 update I will be switching to another phone provider.

You can, but it may break your phone

I too would like to know. They really should make this kind of thing optional.

Same here, I hate the new UI so much. It looks like a child's phone toy.

If you happen to find a way to downgrade you would lose all future updates since the instant you did a update it would go right back to 7.0

If your battery life is poor any update to software it sounds like the phone needs to relearn usage patterns again. There are a few things you can also try, refer to this link.

@Anonymous "The only way I know of to get back to One UI 6 is to factory reset your phone,..."

Not true. That does not undo firmware updates.

No factory reseting will not take the device back to the original software.
