Optimization for old/low end/small RAM android phone. No root needed.

Optimization for old/low end/small RAM android phone. No root needed. We will need an App called brevent, which basically disable some system and pre-install app, and also "put unused app into sleep". Brevent need to connect to android wireless debugging first. If you have any question, please leave a comment, I'll try to help whenever I see it. First video, thank you for watching!
