Won't save to SD card. Tried changing path several times. It always changes it back to internal storage. Also  on my new Samsung J3 Nougat phone  pictures were coming out upside down  until I calibrated the sensor in your app. Now  photos are right side up but time stamps are still upside down. Should be a way to rotate  flip time stamps and place them where you want on photos . Images look great but these issues are deal killers for me. Uninstalled.
