Hi @alombardojr,

Welcome to Trend Micro Home Users Community!

For clarification, are you saying that Trend Micro Mobile Security is the one causing the shut down on your Android phone?

If that is the case, you may check for other factors:

• Check your Battery Health: Ensure your phone's battery isn't degraded. Over time, batteries lose capacity and may cause the phone to shut down prematurely.
• Overheating: Excessive heat can cause phones to shut down.
• System Updates: Check for any available system updates for your phone. Manufacturers often release updates that improve stability and fix bugs.
• Background Apps: Close any apps running in the background that you're not actively using. Background apps can drain battery, potentially causing shutdowns.

Hope this helps!
