1TB Photo Stick for iPhone Flash Drive, iPhone Memory Stick Thumb Drives External Storage Compatible with iPhone/iPad/Android/PC (Silver)

Does this product search out all photos on computers, iphones, ipad automatically and transfer them to the stick?

My drive worked for a week but after that week, my pc nor my phone does not see it hence i am not able to use it. how does the warranty comes in

How many photos and videos will this store? And, once photos and videos are on flash drive, can the same flash drive be inserted into PC to transfer?

Can i transfer files from android and pc then view them on a mac and iphone?
