It depends on the device storage and RAM.
After taking or importing a large number of photos, CS takes up a lot of RAM and memory to process the pictures. If there is a insufficient RAM or memory, processing may be interrupted so that the program would crash, and the pictures would not be saved.
According to the lab tests, CS can take or import 200+ photos each time. However, if you have installed a lot of apps and your phone's Android/iOS system is relatively old, we recommend that you take or import not more than 25 photos each time.
