The gimbal is compatible with the Samsung Galaxy A53, as this model is officially supported by DJI for the Osmo Mobile 7 series. The Oppo Find X5 is also compatible with the Osmo Mobile 7 series, as Oppo smartphones are generally supported and the dimensions and weight of the devices fall within the range required by the gimbal. It is important that the smartphone weighs between 170 and 300 grams and has a thickness of 6.9 to 10 mm and a width of 67 to 84 mm so that it fits into the magnetic holder. If the smartphone does not fit directly into the holder, the DJI OM Magnetic Quick-Release Mount can be used as an alternative.
