Performing a soft reset - Samsung Omnia (i910)
A soft reset is the most useful tool for resolving a variety of issues. In most cases, a soft reset will not affect the data on the device, unless the battery is very low. Nevertheless, it is good practice to perform a sync operation before any reset to ensure that your data is backed up.

Remove / disconnect all third party devices (e.g. SD Card, headset, etc.).
Use the stylus to gently press and release the reset button (located on the upper-right edge of the device).
