You should know the process if your iphone 12 ever freezes, starts behaving strangely, becomes unresponsive, or hangs up when you turn it on. A force restart will help you with this issue. To perform a force restart on any of the iphone 12 models, you must do the following steps;
Click and release the Volume Up button.
After that, click and release the Volume Down button. No need to press and hold down the button.
Then quickly press and hold the Side button for around 10 seconds until.
Release as soon as you see the apple logo.
While these steps will try to restart your iPhone 12, it may not totally fix the problem. You can always search from Apple’s support pages for more advice if the iPhone won’t turn back on still.
