Samsung – Do this before Factory Data Reset

I am using a Samsung Galaxy A10s smartphone, and I am planning to do a factory data reset because a lot of storage is consumed with unnecessary apps and I am also getting messages such as Bluetooth Keeps Stopping. Therefore, it is a good idea to do a Factory Data Reset.

This action will reset your phone to its factory default settings. This will erase all data, including files and downloaded apps. Therefore, you must backup your existing data before executing this action. Backup might include your Contacts, your WhatsApp data, your Notes, and other stuff. I am done with the Factory Data Reset of my Samsung Galaxy A10s. I am listing my steps here. It will be a valuable resource for me in case I decide to do a factory reset at a later stage anytime. It will also be beneficial for the readers of this blog post who are also planning to do a Factory Data Reset of their Samsung Smartphones.

Samsung now offers a Smart Switch app to backup and restore data. This option is available under Settings -> Accounts and backup. When you tap Bring data from old device the first time, you will be asked to Download Smart Switch. However, the app does not backup WhatsApp chat history, which is one of the most valuable data for a smartphone user. Moreover, when the data is restored, the restore process installs all the previously-installed apps one by one. It is not a good strategy because one of these apps might be a source of the problem and reinstalling all these apps may come up with all previous issues again.

So, my recommendation is to back up the following five pieces of information only 1) Contacts 2) Messages 3) Notes 4) WhatsApp 5) Gallery. You should also note down the list of all apps that you will install after the factory data reset. You should download these apps fresh from Google Play or Galaxy Store instead of installing them from the backup. Now, I will tell you how to take a backup of these five pieces of information.
