Once you unlock the bootloader on the Samsung Galaxy Grand 2 smartphone, you can start flashing a custom recovery, custom ROM and get root access. Without the bootloader unlocked, you will probably brick the device. What most people don’t understand is that by giving your device root access you are returning the Android OS back the way it was before Google touched it. That means you aren’t doing anything bad; you are just returning it the way it should be.
Google locks the operating system so your devices don’t have root access. They do this on purpose because it offers additional security. The reason the security changes is with root access the apps from the Google Play Store have a far greater chance of reading each others data. Since malware and malicious files are most commonly swapped from applications, you could imagine what the security would be like with the entire world having root access and clicking the wrong files. From that point of view, we can understand why Google did what they did. However, for those of you who know what to click and what not to click on the Google Play Store, you can have much more fun with a device that has access to the root file system. That’s what we call root access on the Android operating system.
