A:AnswerAndroid screen black can be a result of installing a bug or incompatible apps. If you have recently installed an app that crashes frequently, that may be the reason for the issue. Uninstalling the app from the device may solve the problem with ease. For doing this, you need to boot your device on in Safe mode.
