Brother and Sister APK: questions and answers
Can I install this APK over the version I already have?

Is the Brother and Sister APK safe?
No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is 3073e23bceb8617813f8485d1049ef3a.
