Hi to both,

you can “get rid of” the high CPU usage by disabling File Shield in Shield Control, but I have a feeling that this is not really our issue anymore. You both probably have some app(s) that keep writing file(s) to your SD card (for example some cache file being overwritten every few seconds). The job of the File Shield is to scan whatever is read/written there. It’s unfortunate that Android (and mobile devices in general) don’t have any concept of “HDD indicator” as is on computers. I’m pretty sure that you would uninstall an app from your desktop if it would be writing something all the time making your HDD LED shining all the time. Right now there is no way of discovering such apps on Android :frowning: (And be assured that constant writing on SD card might impact your overall device performance, even though the impact is lower than it would be on a desktop).
