I lost 2 days of holiday shots so you may want to read on to avoid it. I saved my photo to an 64 gb external SD card by selecting it in Camera setting - memory card instead of phone. Initially, there was no problem and whatever photo I took remained in the DCIM\Camera folder on the external SD card. However, 1 night when I turn off the phone for charging and when I turn it on again next morning, the DCIM\Camera folder on the external SD just got deleted immediate after the phone finished it boot process. Subsequent to that, I managed to re-create similar events by restarting the phone and each time, the folder just got deleted when the boot process end. I will be bringing the phone to Samsung service center tomorrow to show them the problem. Hopefully, it is a specific device problem and not a problem for all Samsung Galaxy Note 2 installed with Jellybean 4.1.1 with a Sandisk class 10 64gb micro SD card. I will report back once I have an answer from Samsung Support Centre. In the meantime, you may want to set your Camera setting to phone to prevent losing your favor moments.
