    But how do you completely uninstall an app from your android? I clear the cache but the app still uses space in internal storage. I installed lookout and cleared the cache awhile ago, but it still uses internal storage. How do I get rid of this and the Cheetah Mobile apps, mentioned here, completely from my android so they occupy no internal storage?

    When you're uninstalling an app, don't just hit the 'Uninstall' button. Try tapping the 'Force stop' button first, then the 'Clear data' button, and then the 'Uninstall' button. The 'Clear data' button deletes the app's settings and saved configurations, along with the app's cache. The 'Uninstall' button just removes the app data itself, not necessarily everything relevant to the app.

    FYI, this is a Cheetah Mobile ad for Clean Master.

    English is not their first language in China...

    Judging from this I'd say it's not even their second language Big Mike, lol.

    Well, I have used many of the app cache cleaners. The only thing they did is, SLOW DOWN MY PHONE TO A PATHETIC LEVEL. I repeat, these app cache cleaners available on the play store are useless and just a burden on your phone's memory. Just use your phone's own cache cleaner, it's the best...

  11. Root your device, download Terminal Emulator, open and type
    Code (Text):
    1. su
    When you see the prompt with # at the end type
    Code (Text):
    1. fstrim -v /cache
    Code (Text):
    1. fstrim -v /data
    and if you are brave enough
    Code (Text):
    1. fstrim -v /system
    All of these utilities mentioned are already built into Android. Which derived from Linux, the worlds most secure Operating System.
    Most security and cleaning apps do nothing more than drain your battery, send your data overseas, or just flat out lie.

    Don't use third party apps for security or clean cache. You can clean your app cache from setting>app. Select desired app to clean cache and do it. When you use any cleaner apps it may delete files from your shareit folder. I've faced this problem. I've lost my photos and videos. Then I've uninstalled the cache cleaner app and never install it again.

    This fits right in with the other absurdity of 2016. Since you didn't tell their app to send your personal data ... who is sending it ... only other possibility is Cheetah Mobile. Since they cannot guarantee the security of the data ... why are they sending it? A basic truth ... when you catch someone lying to you (and I did) ... and you cannot trust ANYTHING they provide.

    Hi, I realised that Clean master App is installed on my new android phone as a system App, I can't unistall it. Any advice?
  15. If it has a Disable option then disable it.

    I realise now that though Clean master was installed by manufacturer, it's possible to unistall it, I have done that already. I thought it's a good App since I found it in my brand new phone.

    Is there a real legitimate App that cleans up android system?
