Sales of so-called dumb phones have seen an increase for the first time in years.

Phones that simply make and receive calls are known in the industry as feature phones and are being marketed as a means to switch off from the constant connectivity people have grown used to, according to Sky News.

While global sales of smartphones rose by just 2% last year, feature phone sales went up by 5%.

Mobile handsets that simply make calls are being marketed as an escape from constantly being connected to social media and apps.

Research by Ofcom found 78% of British people said they couldn't live without their smartphone while on average users spend 2 hours 28 minutes online on them a day, rising to 3 hours 14 minutes among 18 to 24-year-olds.
