One major barrier which often prevents you from factory resetting your Android phone is the fear of losing precious apps and app data. Or perhaps when you buy a new Android phone, you would want to take away some apps with you. Here are some ways to achieve this.
The simplest way to do this is by enabling the option in Settings>>Backup and Reset>> Back up my data. This allows Google to store full record of list of your apps on all devices. When you setup a new device for the first time or after factory reset, you can enable sync with Google when prompted and apps will download to your device automatically.
Google Play Store on Android
It is likely that not all of your apps will be downloaded automatically. You can manually select Apps for better reliability using following steps.
Step 1: You can open playstore app on your android phone and select My Apps from menu.

Step 3: Scroll through this list and tap on apps you wish to install, grant permissions and hit the back button
Step 4: Now tap on another App and repeat step 3. This way, all apps you want will queue up for downloading
Take a break and when you return, all apps would have made it to the list

Rooted users have several effective options but when you are switching to a new phone, it’s not always possible to use a root it.
