Mysterious Dev 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 Mysterious Dev 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 98da334464fcc4a0e1f6d767c613635f.
