Contact Backup APK: questions and answers

Is there a version of Contact Backup for older Android phones?

The current version needs Android 4.1 or later. Version 1.3 is the newest listed build that installs on Android 4.0 and later. It is an old build: apps that rely on online services may no longer connect when they are this old. Get version 1.3 · All versions

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is the Contact Backup APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. It is signed with the same certificate as the other version checked. After downloading, check that the file's MD5 is c331b9ed37030f1118567907aef8393c.
