So awhile back, i lost grip of my Samsung Galaxy S6, thus it it hit the ground, the screen went blank and the LED Showed a Blue light. I'm not sure this phone is rescueable as the Front Glass is also cracked due to dropping it a previous time (near the Front Facing camera). I believe it's done for, by maybe someone can find a way to bring the tank back to life!
Probably can be saved ....BUT ,the question is : would you want to ....? What i am saying is : most likely the display is broken , as well as the digitizer ( the front screen) . That probably would cost you at least 100 - 150 £ . I don't think it's worth it
