The images made by the spark, are not being recorded on the phone, but it saves on the memory card of the spark.What should I do?

do you have enough memory on your phone?

Have you checked settings in dpi go ?

by default the Spark only saves low res photos to the phone and full resolution photos to the SD card. But, in the past when my phone fills up or it tells me that the "cache is full" it will stop saving to my phone and only save the high res pics to the SD card. Hit the play button in the bottom right corner of your screen and then on each picture hit the download arrow button. This will save a full sized copy of that picture to your phone.

There’s a setting in the app to save images in the phone or not. But even if you do, they will be a lower quality than the ones saved on the SD card.
