However, survey revealed an array of other phone options that outnumber messaging popularity by a large margin. Gaming was identified as the most popular among surveyed users. Respondents rated gaming by 2 points on a 10-point scale, where 1 corresponded with the most favourite feature. Accordant to the respondents, camera, internet browsing and social media were much less favorite features in their mobiles.
