When your device's screen becomes unresponsive for any reason, it doesn't necessarily mean it's broken or that the issue is hardware-related. Consider the following scenario: your iPhone won't switch on, and you suspect the battery or another component is faulty. The majority of the time, it's just a software failure. The issue can be resolved by doing a hard reset. The iPhone's red screen of death is the same way. Because you can't access the iPhone settings via your touchscreen, the first thing you should do is perform a hard reset. Don't worry, none of your information will be lost.
- At the same moment, press and hold the Home and Sleep/Wake buttons.
- Hold the buttons down until the Apple logo appears on the screen (some people say you need to hold them for 10 seconds, but it usually takes more time)
- Release the buttons when the Apple logo is displayed.
- check if this method work or not
