I've had a few occasions where I've taken photos and the photos have failed to save. If I click the picture in the camera app I get a message the photo saving isn't finished please wait. But later there is/are no photo/s. A reboot can often solve the problem but I'd like a reliable way to take photos please. I have an sd card in the phone if that helps you.
I suffered from a similar problem on Nokia 5 where saving photos failed. The device asked me to reinsert the SD card as it couldn't detect the card. I have tried re-inserting & rebooting the device but the device still doesn't detect the card.
I would like to know if anyone has a way to crack this issue.
