How To Clear Devices I Get It To Settings The Can't Figure How To Get To Delet

1. Open your phone's Settings app.
2. Tap Apps & notifications.
3. Tap See all apps the app. Storage.
4. Tap Clear storage or Clear cache. If you don't see "Clear storage," tap Clear data. Clear cache: Deletes temporary data. Some apps can open slower the next time you use them.
5. Go to your phone's settings, and select "Storage." Among other things, you'll see information on how much space is in use, a link to a tool called "Smart Storage" (more on that later), and a list of app categories. Tap on the blue "Free up space" button.

I'lll take the approach from the point of view of the "lower-end" of town: Embedded devices - special-purpose devices that usually only serve one (maybe two) purposes. I'm thinking clocks, "smart" appliances (really, any appliance with an LCD and/or buttons), keyfobs, etc.

Most of these devices make use of of an internal bit of hardware called a "watchdog" or a "Computer Operating Properly" (COP) timer. If the watchdog/COP isn't serviced within a certain time, the microcontroller is reset. This is one (most frequent) way they get rebooted. Sometimes, the device finds an error condition and the programmer has decided the best way to deal with this error is to reset the device to a known state. This often (but not always) involves the watchdog/COP.

As for restarting, sometimes the device wakes up when it sees an event. An input could trigger an interrupt that wakes the device up. I see that often. Sometimes the watchdog/COP is used to wake the device up (because it can). Sometimes, the device is shut down to a sleep state with a timer running, which wakes the device up when it expires. It all depends on the architecture of the microcontroller and the device itself.

Many microcontrollers include a register which tells the program why the micro was last reset. This can be quite useful for this sort of device.
