Animation- the biggest thing i saw was Animation and transition quality and speed.....like my device just got renewed.....everything is feeling fast....and the controls in Samsung Home up(in good lock) are feeling much better....the ability to customize my device is increased a lot
Home screen- ability to keep icons anywhere and even stack them on each other(need to be enabled).....it feels great to keep whenever you want....but the stacking of app seems bad...like if i install 10 apps it will get stack on each other and overlap making it difficult to handle....ability to add sticker seems fun
Now bar- works on lock and AOD......gives refreshing look....and the fact that we can add multiple functions is good
Heating and performance- i noticed that my device is not Heating as much as used to be before...we all know the fundamental problem of s22 series is Heating issue......but seems it got resolved up to a point
Another thing I noticed is that when i unlock my phone on from restart it earlier it showed the phone starting Animation that took couple of seconds before you perform any action....but now it's not there.....
Layout changes- Wasn't hyped much but a transition is welcomed....
In order to check what really has changed people should check out Samsung good lock application......it got a major update
One ui is known for user compatibility and one ui 7 is really standing on that note
This was my experience observed over few days.....it may not be much as little things get overlooked......You all can mention features and changes that i missed (there are a lot)
