One UI 6.1

Horrible update. I moved to samsung for purpose of customization. Seems like they are now going the opposite direction. Cannot change clock style or colour seperatly on always on display as well as auto brightness on always on display. As well as this old swipe gesture has now been removed from navigation bar. I was used to swiping up from the right side to go back. What's the point of removing features? Makes no sense. Always the edge lighting used to brighten the screen when notification received if screen is dull. So many awful issues. I want my old update back.

Use Goodlock and Lockstar and Navstar apps to customise as it was

I have done that but still not the same like the colours keep showing the same as lock screen

With Lockstar you can change the colour (single) of icons. Multi coloured icons supposedly to come/return with Android 15

Take a look on the samsung appstore for the good lock and related apps. These are designed to help you customise your phone further than the average user. https://apps.samsung.com/appquery/appDetail.as?appId=com.samsung.android.goodlock

You have to use both the lock screen and the goodlock options to make the changes you want. For example, changing colours would be done in default settings. After playing around a bit, you'll notice where the changes would have the best effect. Here, I've customised my home screen Icons. You even have options to edit or modify individual app look and iconnpacks.
