And 46 per cent admit to not protecting the content.
Norton by Symantec has observed the behaviours of UK mobile users to find that 39 per cent could never give up their device, while 23 per cent said it would be one of the top two personal effects that they'd rescue if their house was on fire.
As the mobile is increasingly acting as a pocket-sized PC, 63 per cent admit to storing sensitive data on their phones, although 46 per cent say they don't protect the personal content with passwords or other security features..
Richard Clooke at Norton by Symantec, said: "People are relying more and more on their mobile devices to navigate, share, socialise and shop in today’s constantly-connected world.
"What many consumers may not realise is exactly how much of their personal and private information is up for grabs should these devices be compromised, lost or stolen. Considering the sensitive nature of data that is accessible from personal mobile devices, consumers need to take some basic, yet easy, precautions to protect it from falling into the wrong hands."
