I have a problem with selecting ICMP protocol in droidvpn , hammer vpn , troidvpn .... etc .
note that : My phone is s7 edge ( sm-g935fd ) and i have root on it .
in droidvpn when i select icmp it showes this message to me ( you can only use ICMP on a rooted device )
in hammer vpn it gives me that the has been granted superuser permissions and then gives me thid message ( to run icmp tunnel device must be rooted : attempt to inkove virtual method ' int java.lang.string.indexOf(java.lang.string)' on a null object reference ) i don't konw what is the meaning of this message and i don't know what is the problem Until now :crying:
