Before you buy a new cell phone or new tablet, please try the following procedure to repair your device. First charge your battery, backup your important data if possible and in most cases take out SIM and SD card before factory reset. It is impossible to recover your data after doing a hard reset, so online backup is always important. For all of your data, a backup should be done on an external device, hard drive, raid system or media. With or without insurance, if your cell phone lost, damaged or stolen at least your invaluable data is backed up in a safe place. If you are about to sell your phone and you want to wipe your personal data, or if your phone affected with virus you have to do a hard reset. In some cases, you can delete the forgotten password or lock pattern from your device as well. All information is for devices with stock based ROMs. If you are using rooted device, always back up your EFS folder first, containing your IMEI info, etc.!

    Resetting your Acer S200 smartphone

    not locked. Press any key or tap the screen to see if the phone
    responds.

    Reset

    A reset will clear the RAM of your smartphone. It is similar to turning a computer off and then turning it back on.

    Important: To reduce risking damage to your smartphone, only use the supplied stylus to reset the device.

    Use the tip of your stylus to lightly press the Reset button inside the hole on the side of your smartphone.

    Clean boot

    Warning! You should only perform a clean boot when all other
    reset options have failed to restore your smartphone to an operational
    state.

    A clean boot will restore your smartphone to the state it was when you got it from the factory.

    Warning!

    This will erase all your personal information, any contacts stored on your smartphone and any programs you installed.

    If your screen is responding to stylus input: Go to Start > Utilities > Default Settings. Read the warning information and enter the security code in the empty textbox. Tap OK to proceed.
