My mobile security seems to be on all the time. Although VPN is on most of the time, it does turn off sometimes when I'm not using the phone.

Hi @lielm75068,

Welcome to Trend Micro Home Users Community!

I'm sorry that this happened. 

Please be guided that Mobile Security's Web Guard and VPN app uses a local Virtual Private Network, or VPN on your device. With this, they are complicating to each other and will causes some performance issue. 

It is based to use one at a time. 

Hope this helps.
