I had trend micro system tuner installed on my phone.  I broke my phone and sent it to get repaired.  When I got my phone back  system tuner was missing.  I reinstalled trend micro but now I can't find system tuner

Hi @franks440dart,

To enable the App Stop or App Freeze feature of Mobile Security, here's the link: What is App Freeze in Trend Micro for Android? | Trend Micro Help Center

Also, to add the App Stop shortcut to your Home screen, please follow the instructions below:
1. Open Mobile Security App.

2. Tap App Stop or App Freeze.

3. Tap the App Stop Logo on the upper right and then Tap Add Shortcut.

Hope this helps.
