TWRP Recovery for Galaxy J4 Plus

Galaxy J4 Plus comes with very mediocre hardware and software. If you wish to get the full out of your Galaxy J4 Plus, flashing TWRP recovery is the way to go. TWRP recovery will open your ways for custom operating systems. Most of the custom ROMs come in the form of ZIP files that you can flash via TWRP recovery only. If you are looking forward to making a Nandroid backup, and also backup all other partitions of your Galaxy J4 Plus, you will find all those options in the TWRP recovery. The recovery also has an inbuilt terminal that can be used to sideload applications, custom ROMs, and Mods from your computer. There is a wipe option that will let you wipe Cache, Dalvik Cache, and the individual partitions of your phone. The TWRP Recovery has the advanced options for the users who want to go an 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. Flashing TWRP is not recommended by the phone makers, however, if you think that you can handle it well, you can install it by following the appropriate instructions.

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. 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. It is totally up to the users whether they want to root their phone or not.
