Removed a description of custom Android launchers because this doesn't not fit in a section about bootloader unlocking. Unlocking the booloader isn't required for installing an alternative launcher. It is only the custom ROMS (which a different operating system) that require it. Also removed "essential" so it has a more neutral tone. |

*When the bootloader is unlocked, Samsung devices have their KNOX fuse tripped, which voids the warranty and restricts access to apps such as: Secure Folder, Samsung Pay, Samsung Pass and Samsung Health. These restrictions apply even after relocking the bootloader, meaning that gaining control over your own device requires you to give away some of the functionality you paid for and possibly hurting its aftermarket value.<ref>{{Cite web |date=7 Mar 2025 |title=Trusted Computing Platform |url=https://docs.samsungknox.com/admin/fundamentals/whitepaper/samsung-knox-mobile-security/security-principles/trusted-computing-platform/ |access-date=29 Jun 2025 |website=Samsung Knox Documentation}}</ref> | *When the bootloader is unlocked, Samsung devices have their KNOX fuse tripped, which voids the warranty and restricts access to apps such as: Secure Folder, Samsung Pay, Samsung Pass and Samsung Health.
