The content - including footage of a monkey that appears to be trying to eat the phone - has been widely shared on social media since Zackrydz Rodzi posted it on Twitter.
The student said he thought his phone had been stolen while he was sleeping.
But it remained unclear exactly how the mobile went missing.
It was also not possible to verify the circumstances in which the photos and videos ended up on his phone.
Mr Zackrydz, 20, told the BBC he realised his smartphone was gone when he woke up at around 11am on Saturday morning.
