However, if you rely on Samsung-specific features (Secure Folder, S-Health, or VoLTE on specific carriers like Jio in India), verify with the ROM thread first. VoLTE works on LineageOS 21 but may break on older builds.
However, the journey to a custom ROM is not without its perils and prerequisites. Unlike an official over-the-air update, installing a custom ROM on a Samsung J7 Nxt is a technical process that voids the warranty and carries risks. It requires unlocking the bootloader (a process that triggers Samsung’s Knox counter, permanently disabling some security features like Samsung Pay), installing a custom recovery tool like TWRP (Team Win Recovery Project), and then carefully flashing the ROM and Google Apps. For the novice user, this can be daunting. A wrong step—such as flashing the wrong file or interrupting the process—can result in a "hard brick," turning the device into an expensive paperweight. Moreover, no custom ROM is perfect. Users often encounter minor bugs, such as camera quality degradation (since Samsung’s proprietary camera drivers are hard to replicate), FM radio issues, or slightly reduced battery life during the initial stabilization period.
