My S23 is now extremely slow, won't open some pages, cuts out and loses charge sinsthe last update, the graphics and layout have changed, its so hard to find things now.

Can it be reversed?

Hey there and welcome to the Samsung UK and EU Community Forum

No the update cannot be safely reversed.

1. Wipe Partition Cache on your device

2. Wipe cache from each app, especially the Internet one you use

3. Graphics and layout can be changed to suit your needs. Lots of threads on this already so please perform a search.

You have a very customisable device, you just need to learn how the update has improved it.

1. Turn off the device.
2. Connect To Computer USBC to USBC (you may also connect to another Samsung mobile via USBC). Press and hold the Volume Up key and then press and hold the Power key
3. When the Android logo displays, release both keys.
4. Wait until the Android system recovery menu options appear.
5. Press the Volume down key several times to highlight wipe cache partition.
6. Press Power key to select.
7. Press the Volume down key to highlight yes, them and press the Power key to select.
8. When the wipe cache partition is complete, Reboot system now is highlighted.
9. Press the Power key to restart the device.

What things are you finding hard to find? Personally I think there's almost no difference with settings and most features since One UI 1 let alone the last update. All features and menu options all appear almost identical to prior OneUI. If you specify what things you're finding hard to find, perhaps some of us here can help.

The One UI is a disaster. And it's not a solution to create patches or fixes for it. The volume of bugs are so many it merely creates layers of more problems.

It's so bad I want a full refund for my phone. I didn't spend £1,200 to be confronted with the mountain of problems the One UI is causing with the phone, from charging issues (which makes it difficult to charge the phone), to battery issues (which drains your battery basically while you watch), to spelling corrections (that is always wrong), camera issues, and on and on. It also messes up the notification sounds and you can't switch them back. The battery drains 30% overnight while not in use. Turning off background apps, lowering screen light, etc., does nothing to improve performance. And if you switch to battery saving mode the entire screen switches to dark mode.

I basically have every single app in deep sleep mode and even that does absolutely nothing to improve the rapid battery drain. I can only imagine how much this will damage the lifespan of the battery in itself even if they fix this - and Samsung will have to cover a free battery replacement at no cost.

I am infuriated. This phone has turned into a useless decoration, total cr*p, with the latest update.

It's been nothing but a disaster with this update and more so with the fact that you can't even reverse it and go back to the previous version.

I' ve tried every single troubleshoot recommendation, spent (wasted) hours on it. Nothing works. One UI is a total disaster. I want to reverse back to the previous version but you can't do it once you switch to this disaster One UI.

I have a Galaxy Z Fold 5 and after the update, my phone is virtually useless. Extremely slow, have to clear cache on every app or it won't load and battery live is down by 50%
