sorry for my bad english…

but I was not able to detect the location of my tablet in avast web pages.

please be more specific about this.
can you locate using SMS?
do other web commands work?
do you get an error? if yes - where and what?

I’m so sorry.
I have nexus 7 WiFi, so I can’t do it with sms command.

Yes, I can connect with it. But, it must connect to the network.
It is possible to locate my device without connect to the network?
By using GPS maybe?

There is no error message. I’ve done the installation well.

Sorry for my bad english…

Hello,

a wifi connection is necessary in your case. the app can of course use GPS to determine the location (if the device is outdoors) but needs wifi to communicate with the server.

have a nice weekend,
