Switch off blinking screen when making phone calls
Hi, can anyone tell me how to stop the Xperia S stock phone app from blinking on and off (the whole screen) when making a call? It's such an unnecessary annoyance but can't find any settings for the app anywhere.
Sometimes new users post on old threads, like yourself, the last reply before your first post was back on July 2014, your post was August 2017; also, sometimes new users post in "incorrect" parts of the forum.
