I plugged my smartphone to be charged using a car charging adapter. My phone will not turn back on at all! Have I ruined my phone?  I plugged my smartphone into my car charger no light appeared so I brought inside tried it there still no light and now my phone will not go back on!  Help!
Is the car charger of good quality? I would try removjng battery,  putting it back in, plug it to wall, wait a few minutes and press and hold down power button
