why can't i view pictures and songs i send to my lenovo phone

[AC Question]

Each time I send a picture from another phone to mine through Bluetooth or I screenshot, if I try to open it, the pictures refuse to show and it says thumbnail not found on the blank screen. If I go to gallery, I just see blank spaces of the number of pictures received. Also, if I transfer music from a laptop or phone to my phone. I see the songs but when I click to play, it says cannot be played. I've flashed the phone as they suggested virus but it's still the same thing. It wasn't like this before. Pls I need help.
