At times when I turn on the phone it turns off immediately or after a while,
and if I try to turn it back on instantly it won’t turn on again before an hour or
more sometimes and sometimes less; Most of the time before it turns off
completely I get a black screen ; During that time I can receive and answer calls because
for a short moment the screen comes back on again. In other words it’s fooling about
and “ When” it works , it would be only for a very short while.
