All Android devices request a Google account to set up the device, but the user can ignore and use the device without the use of Google. Should the user opt to use the device without a Google account, their data will not be backed up. Should you have a device lacking the use of a Google account, search for backup programs that the user may be relying on to protect his data should his Android fail or the device is lost. Most devices are not backed up by the user even though backup programs are available. An example of backup software is Samsung Kies, which has an .sbu file extension and can be parsed with a tool like MSAB XRY. Other backup software that you may come across includes Samsung Smart Switch, which is popular when acquisition for the devices isn’t working. For Huawei, the HiSuite (PCTool) or Kobackup (APK) are options. The advantage of using HiSuite and Kobackup is that they both contain backup of App data, no matter if the app is preventing an ADB Backup. There is a tool to decode these backups created by RealityNet. A blog on the methods can be found on https://blog.digital-forensics.it/2019/07/huawei-backup-decryptor.html. You may also find the use of LG PC Suite to be helpful.

Regardless of solutions to backup, most Android devices simply rely on the use of Google. This cloud-based syncing service provides the user the ability to store and sync data for free (up to 15GB).

Gaining access to Android backup files and creating an Android backup for a forensic examination will be discussed shortly. Legal authority or consent is required to access and analyze user backup files, even if you stumble upon them. Always make sure you have permission to examine the media and backup files associated with the Android device.

Android Device Manager was introduced as the answer to those seeking a similar solution to the iOS Find My iPhone application. Android Device Manager was renamed to Find My Device and is accessed by logging in to the user's Google account. This account must be the one associated to the Android device you want to access. Just like Find My iPhone, a list of Android devices associated with that account are displayed. From here, the user can locate a lost Android, ring the device, and perform a remote wipe. At the time of writing this, Find My Device does not automatically enable remote wipe access unless the feature is enabled by the user.  A remote wipe renders the Android untraceable, as the device must remain active and online for Find My Device to track and access it.¹ For Samsung devices, Find My Mobile can provide the same features.²
