Hi @vympler and welcome You already opened a thread about it. https://forums.ubports.com/topic/6357/why-we-not-change-lock-screen It has been closed to redirect you to the open topic: https://forums.ubports.com/topic/6022/login-screen-code-input-design/ There is already work in progress regarding a new lock screen, so you can contribute there. And you can also check out these projects that might get you what you want: https://open-store.io/app/uhome.pavelprosto and/or https://open-store.io/app/launchermodular.ubuntouchfr Multiplying the threads won't help you but it starts to look like spam, so please search the forum prior to posting and read the documentation or threads you're referred to.

@vympler I moved your post to OT as it did not really belong in Porting as it was not about a specific device, please see https://forums.ubports.com/topic/206/will-you-port-to-device-x If as @Moem has said you check out the documentation you will find out that porting is not an easy process and has to be done for each individual device. Along with a small team of full time devs and a host of volunteers it all takes time. If you want to help out there are many who can and will give help and assistance when they can. Last thing please try and make your questions less random and we can avoid any confusion with trolling, which I think has already been pointed out in another thread and give you a much better and informed response. We also have language groups if that helps https://ubports.com/meet-the-community
