Security & authenticity
Signing certificate
- Certificate issued to “rockz5555 OU=Droid Freedom Unit O=Droid Freedom Inc L=Unknown S=Unknown C=LK” Not the developer's name (“Yasiru Nayanajith”). Names in certificates can't be verified, so this alone proves nothing.
- The same certificate signs apps from 23 different developers Developers sign only their own apps, so this almost always means the files were re-signed by someone else — often after being modified.

Device Info: System & CPU Info APK: questions and answers
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 Device Info: System & CPU Info APK safe?
No one can promise that a file is safe, but some things can be checked. The source store rates this file Unknown. Its signing certificate is also used for apps from 23 different developers. After downloading, check that the file's MD5 is c25bb694e66fa724ecc8588f6c80a811.
