I guess all the Android user must install those types of apps for cleaning ram and cache memory. but realty this app is doing nothing, even they will slow your phone.
you don't need anything to install in your phone. those types of cleaning app may kill your phone.
from my opinions big no to all those cleaning apps and antivirus, Bettry saver app.
they are just makes money through your phone, be careful.
have a smart thing to do.
