If one ask any technician, he will come to know that in androi phone these apps are unnecessary. One must not use these apps like Go Speed or any such.
These apps instead of cleaning your phones, slower down the phone’s process.
As much I know android works automatically. It doesnot need any cleaner. Whenever we open an app The processor uses the ram to run the app. And after we close the app ram automatically released.
When we use such cleaning apps they shows ( 100mb/500mb/1gb) junk blah blah all these results are not accurate.
Even many other antivirus app are too unnecessary for android. Because android protects itself. I won’t need any antivirus so long we install or download apps or other files from trusted source. The best way to keep mobile safe is to download filea from trusted site.
Coming back to the point of cleaning app, these are totally worthless in my opinion.
