It happens rarely but this can be handy if your iPad freezes someday. It’s kind of like first aid for an iPad. Works on iPhone too.
When your iPad does not response to you no matter what you do to it, here’s what to do.
Press and Hold The Home Button and the Power/Standby Button at the same time for about 10 seconds or more until the iPad turn off.
Release both Home and Power/Standby buttons.
Turn on the iPad by pressing and holding the Power/Standby button until the Apple Logo appears.
I hope you find this guide helpful.
