Maybe write in the article that with app called "Illumination Toolbar Notification" u can control the light bar? :)

Article really needs to be undated as to when the Xperia U was discontinued

edit

I assume this phone like all other Xperia phones is no longer being manufactured or sold new so the article should state when Sony stopped making/selling this phone. --Notcharliechaplin (talk) 21:18, 16 January 2019 (UTC) — Preceding unsigned comment added by Notcharliechaplin (talkcontribs)
