Question My phone removes images by itself

[Syed Najabat Kamal]

Hi. I am facing a strange problem. I am using LG V10 VS990 Verizon US.
The last saved picture in my SD card is captured on 29 April, 2019. After that image, whenever i capture images, after some time, it removes the image thumbnail, but opens the image. But when i restart the phone all the images captured after 29 april removed. It only happens with sd card.
