Some mobile devices have trackballs, including those in the [[BlackBerry]] range, the [[Danger Hiptop#Hiptop 3|T-Mobile Sidekick 3]], and many early [[HTC Corporation|HTC]] [[smartphone]]s.  These miniature trackballs are made to fit within the thickness of a mobile device, and are controlled by the tip of a finger or thumb. These have mostly been replaced on smartphones by touch screens, although on the BlackBerry range they were replaced by an "optical trackball" or "[[optical trackpad]]" before later being replaced with touch screens.<ref>{{Cite web |url=https://www.pocket-lint.com/phones/news/137319-farewell-blackberry-os-here-are-the-23-best-blackberry-phones-that-changed-the-world |title=The history of Blackberry: The best BlackBerry phones<!-- Bot generated title --> |access-date=2020-08-02 |archive-date=2020-08-06 |archive-url=https://web.archive.org/web/20200806070650/https://www.pocket-lint.com/phones/news/137319-farewell-blackberry-os-here-are-the-23-best-blackberry-phones-that-changed-the-world |url-status=live }}</ref>
