Hello Greetings, The truth does not need an antivirus on Android phone, but if yours is to download unofficial Apps osea outside the Google Play Store or other types of file I recommend Avast Security will scan the Apps or any specific app among other things to improve the performance of the phone. All apps that are in the Play Store are scanned by Google Play Protect so you do not need antivirus on the phone also the most modern phones bring internal antivirus that you can find it in the settings. I hope this will help you.
