Every android user faces problems like virus and extra junk files so am I.
My mobile was working very slow. So I thought of installing any cleaner app and installed Clean master. But it was useless. I got notification of cleaning junk files in some interval. There were so many ads. After using it My mobile also started hanging many times.
It created more problems than earlier. So I had to uninstall it.
So I suggest no one to use it. Its of no use. It only increases your mobile problems
