On created photos we can display a watermark, whereby ColorOS does not offer us many possibilities here. As watermark, the phone model can be determined, as the date and time as well as the location. If the watermark is activated for the model, we have the possibility to determine an own stroke with up to 20 characters.

Unfortunately we have no influence on the position, color, transparency or other parameters.
