The mobile phone with this function uses slimming software. My own mobile phone now uses Tencent Mobile Manager, so I recommend you to download and use Tencent Mobile Manager. It is convenient to download such software, and it also reminds us of our personal safety. Tencent Mobile Manager provides security for users' mobile phones. For example, it can only intercept fraudulent information and accurately identify fraudulent information for risk warning. I hope my answer can help you.
