The recovery also has an inbuilt terminal that can be used to sideload applications, custom ROMs, and Mods from your computer.

The TWRP Recovery has advanced options for the users who want to go the extra mile with the customization on their device.

TWRP runs in the bootloader of the phone. It is also useful if something goes wrong with your phone and you want to restore it back to the working state. TWRP is often useful to recover a soft-bricked Android smartphone.

What does Root mean for Galaxy J4 Plus?

Rooting your Galaxy J4 Plus will get the system access to applications. This would mean that any application that requires root access, will be able to modify the system files of your phone. For example, you want to add a new feature to the UI of your phone and you are using an application to add it, that applications will ask you for the permissions to modify the System UI files. As soon as you grant permission to that application, it will modify the System UI to add that new feature. Similarly, if you want to back up the data files of applications, you will use an application like Titanium Backup to pull those backups from the system directories of your phone. The root is useful to introduce new features and also to enhance the performance and battery life of your phone. Just like the TWRP recovery flashing, Rooting your phone is also a custom process which is not recommended by the phone companies.
