I was trying to make my own custom lockscreen and I would need to change the lock screen ui for this but it wont let me change it. I am using a s10e and I know on my old phone (J7) I could change the ui. Is there anyway I can change it or is this feature removed.
Like on my J7 I could download a lock screen app which will replace the default lock screen so I could customize it to have bigger pattern locks and stuff like that
Due to security reasons, this is no longer available. You can change the home launcher, but you must use stock Lock Screen UI, unless you want to use some kind of Root application, which will void your warranty.
