Jack Lumber 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 Jack Lumber APK safe?
No one can promise that a file is safe, but some things can be checked. The source store flagged this file with a security warning. After downloading, check that the file's MD5 is 9d7e2f32922f4a6b5fa5e3fedb6a41dd.
