USB diagnostics APK: questions and answers

Is there a version of USB diagnostics for older Android phones?

The current version needs Android 5.0 or later. Version 1.0 is the newest listed build that installs on Android 4.0.3 and later. It is an old build: apps that rely on online services may no longer connect when they are this old. Get version 1.0 · 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 USB diagnostics free?

The APK is free to download, but the app offers in-app purchases through Google Play.

Is the USB diagnostics 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 4c9cea3acb035f067874add0a4efa4c0.
