Screen flickers and goes black

    My S7 screen flickers and eventually goes black (except the top portion above the app icons). If I warm the cell by any means (e.g.: hair dryer, etc..) the darkening eases off and eventually cell regains brightness, until it cools, and the problem resumes.

    Any phone that flickers and goes black tells me it's a hardware failure. Take it to your carrier and have them fix it

    Yeh, sounds like the screen has failed, repair or replacement required. An S7 probably isn't under warranty now

    Thanks Danny. But, out of curiosity, what is the explanation of why, when I warm it up, the screen returns to normal until it cools down?

    Some electronic faults can be temperature dependant. Often in electronic circuit fault finding, one might use freezer spray and a heat gun to chill and heat suspect components, like transistors, diodes, etc.
