All Android devices leaking and Google that ows the Android will not send an update patch, so how is Vpn-Client Pro protecting their users against this ?

Hello,

The issue described in the link is in the operating system, so VPN apps, including VPN Client Pro, cannot fix it.
We hope Google decides to release a patch for this.
In any case, a malicious app must be installed to exploit this vulnerability, so check your installed apps and install new apps only through official channels.

Yeah but there must be some release update VpnClient Pro can fix this by releasing a patch on the App ?
Or else Vpn's are wortheless since it leaks and we know that Google won't do anything about it.

Unfortunately, VPN apps don't have the necessary permissions to fix this problem. Google needs to fix this issue; hopefully, they'll change their minds.

This link provides all the details regarding this issue, including a possible workaround.

However, the best protection is to avoid installing apps from unknown sources.
