Camera ans sdxc card

Iam using stock camera-app. The phone loaded overnight and should save pics to sdcard. Also all possible apps are at my sdcard. After some time without changing anything the pictures i am freshly doing dont appear at thegallery or inside the camera-app. I have to disconnect the card per software and connect again. Then i can see the recent made pictures i thought they were not saved to sdcard. Any ideas?? Btw my pho took to charge from 3percent to 100 from last evening 8.30pm to 430am. I am very disappointed from this phone after the lg g2 and think about switching to s6.
