Why do the photos in the album still exist after they are added to Photo Lock?

A: On some smartphones, or with certain photo apps, your photos are synced between your device and cloud automatically. This is convenient but sometimes not very safe (there are more and more account breach events recently). If you find your pictures still exist in the album, please find the system settings or account settings to turn off automatic sync. And then you can remove the pictures from the album permanently.

How to back up the photos in Photo Lock or move them to new phone?

A: Photo Lock allows you move your photos out to a public place in the device storage. After that, you can back up them or move them to a new phone with your own way.

How to reset password/pattern for photo lock if I forget it?

A: Please sign in your Trend Micro account first. When you forget your pattern, you can reset it with your Trend Micro account.

Dr. Safety is a bit Battery-consuming…What can I do?

We’re sorry to hear your feedback. It’s possible that they’re due to the following features: 1) Security Threat Scan-Real-time Scan, 2) Safe Web Surfing. You can try disabling both features to see if your phone doesn’t heat up and battery draining as much, just don’t forget to perform manual scan regularly and be extra careful when surfing the Net.
