It's been the same with my stays. One of the hospitals I went to had mobile phones loaned to you for your stay which were very basic - no camera, no Internet, no media files except for the default ring tones etc but you had to give them back at night and weren't allowed them back until after breakfast. Most of the wards I've been on have had computers for education sessions but only a set allowed of websites are allowed to be used (all others were blocked).

I think it depends on each hospital's privacy policy, as cameras on some devices can invade privacy and these vary on the hospital type too (open, low secure, medium secure, high secure) and also whether it's an adolescent or an adult unit. It can also depend on the circumstances and needs of the individual along with, but not necessarily, their status (informal/voluntary/section).
