    Hello there! I have an Asus Zenfone Zoom (ZX551ML) that occasionally experiences a random high (internal/system) storage device write activity. It won't stop until I restart it. What's really frustrating is that I cannot track which app uses the memory chip, because the system monitor doesn't provide such information. There are no system monitoring apps that can make such information (the disk usage per and by app) available; I can only see the chip having a high write rate, but I cannot track which app does that.

    The occurrence is apparently random - it happened one time after I used the camera and one time, recently, after I plugged the charger in. It also happened after I resumed from sleep. It stays somewhere between 50 and 100 KB/s and it causes a bit of lag - just some dropped frames; it doesn't affect the performance consistently but it's obviously abnormal and anyone would want it fixed.

    I attached a screenshot taken from the app Simple System Monitor. I used more system monitoring apps and all of them provide the same results, so it's definitely not a matter of monitoring app malfunctioning.

    Does anybody experience the same thing or it's just me? I'm looking forward to a solution. Thank you!

    System details:
    > operating system - Android 6.0.1;
    > Android security patch level - April 5, 2017;
    > firmware version - WW_4.21.40.314.

    Welcome to Android Central! Is there a preinstalled or 3rd party backup app? I seem to remember ASUS having its own backup app -- maybe it's periodically backing up data to a local file on Internal Storage.
