Before We Root Samsung Galaxy S3 i9300
Rooting is a safe process but you never know what would happen next. Very unlikely, but you may end up with losing the whole data on your phone. This is why you should always create a backup of your android device. Also create a backup of your contacts and text messages because you may lose your text messages, multimedia messages, and contacts during the process. You can also make a backup of your apps and games using your Google account and you can restore the apps once the process is completed. It is better to remove your sim card while performing the root. This action may clear the data on your sim card as well.
