Answer to: Blu Studio 5.5 will not turn onI have Blu Studio 5.5 that wont turn on. My fix is this: Hold the power button down for several minutes. It will eventually turn on. Then search Playstore for an on/off app. It works by detecting light in the camera. Put it in your pocket or upside down on a table phone goes dark. Take it out it goes on. Works for me.
