Before you take it to the repair shop, consider resetting your device to its factory settings to determine if the screen is truly broken or if there's an error in the operating system. Don't touch the power button again for two minutes, after which call it or use Find My Device to see if it will ring. If this happens to you, hold down the power button for 30 seconds, then let it go. It may seem strange that you can receive calls on an Android device with a black screen. If the device has power, you may have a problem with the screen. If the device hasn't been charged, there might be a problem with its power cord, adapter, or even the electrical outlet. Android device users should start by holding down the power button on your device for five to seven seconds, which should restart it.
