This documentation intends to help /e/OS users, backup and restore their device

A difference in the encryption system between Android 9 and subsequent android versions prevents this device from being upgraded to Android 10+ without a factory reset.

Tip: This guide is assuming that you don’t synchronize your phone, for example by using a Murena Cloud account. If you do use such an account, please first check what data is available on the server. You don’t need to back up the data already available on the cloud. After adding your cloud account on the phone with freshly installed /e/ OS, the data should automatically appear on the phone.


  • /e/ OS phone
  • Computer (Linux, Windows, macOS)
  • USB cable
  • Some time : 2-3 hours, if you want to re-install /e/ OS

Step 1: back up your data

Task 1: back up files (Photos, videos and documents)

You need to transfer your files from the phone to a computer.

Connect your phone to a laptop using a USB cable.


Slide your finger from top of the screen downwards, and click on “Android System. Charging this device via USB” 2 times.You will see USB preferences menu. Select File transfer. If you don’t see this option, try using another cable or another USB port on your computer.


You will now see the phone storage as a folder in the file explorer of your PC. You can browse the files on your phone. You can copy all folders, or you can choose which folders to copy, e.g.: DCIM Music Pictures etc.

note: If you are using MacOS, you will need to download and install the Android File Transfer app for macOS. The Android File Transfer can be found at this address:

Task 2: back up your calendar(s)

It is not possible to back up a local calendar. If you are using an online calendar, such as if you use a Murena Cloud account or Nextcloud based account, the online calendar will appear again after adding your account in the /e/ OS after the installation of the OS.

Task 3: back up your contacts

Open Contacts app.

Click on 3 lines icon.

Click on Settings.


Click on Export.

Click on Export to .vcf file.


Choose a folder where you want to save the .vcf file, for example the “Download” folder. Click save, then copy the file to a computer, like in Step 1: “Photos, videos and documents”.


Task 4: back up your SMS/MMS and call logs

It is not possible to save SMS/MMS, neither call logs, with integrated default apps. That’s why we advise users to use SMS Backup and Restore:

  1. Open Apps
  2. Search and install SMS Backup & Restore
  3. Open the app, and create a backup
  4. Copy the backup files (calls-[date].xml and sms-[date].xml) on your computer

Task 5: back up Signal

Please refer to the official Signal documentation

Task 6: back up Whatsapp

The official Whatapps documentation relies on a Google account to backup data: Whatsapp backup and restore documentation

You can refer to the community discussion which provide useful guidelines.

Task 7: back up applications and application data

It is not possible to make a direct backup of applications with the app data. We can offer an alternative to back up user installed apps.

  • For apps that sync data without an account, your settings won’t be saved, so you will have to configure them again after the upgrade.
  • For apps that sync data with an account, you will just have to connect your account again.
Warning: With encrypted messaging applications such as Signal, WhatsApp, Olvid etc. if you do not back up your conversations they will be lost.

To back your apps up, you can use a third party app called Package Manager from Apps.

Once you have launched Package Manager, you will see apps organized by type (All, System, User). You want to focus on User apps, which are the ones you installed on the phone.


To select all User Apps, tick one app to select it then tap on Batch Options and Select All. The Batch options button will now have a number next to it, counting the number of selected apps. Screenshot_20230526-094616_Package_Manager

Now press the Batch options button again and select Export.


You will be prompted to confirm before you export the files.


Once you have confirmed, the export will start.
