I have an iphone 7 plus, I've noticed quite a few times that all of the hard button on my phone stop responding. In example, The power button won't shut off the screen and the home button won't go back to anything. Anything i have on my touch screen is still responsive and i can still do anything with the touch screen, but that's obviously limited to whatever app i have open since i can't get back to the menu. I tried to doing a hard reset with the down volume and power button but the trick doesn't work for me.

Is there anyone else facing the same issue or know how to solve it?

Plz suggest.

I want you to inform that both iPhone 7 and 7 Plus users who are already facing issues with their home buttons will not be too pleased to learn that they may never be able to repair them.Apple confirmed that in case of any damage to the home buttons of the two flagships only a replacement can be done through the company's "iPhone Calibration Machine". No repair by any third-party store or even Apple is possible for the buttons.

So you have to replace your phone if you want to use the hard home button.

However, You should know that there is also a software home button so you don’t have to wait for Apple’s home hard button to respond for your work. The digital button has actually been around for ages, and it’s called Assistive Touch. It’s not exclusive to the iPhone 7, and can be turned on in your phone’s settings.

To enable Assistive Touch, you can use the following step:

Go to Settings > General > Accessibility > Assistive Touch, then turn on Assistive Touch

This is gonna work for you till you make up your mind for a replacement.

Hope you are satisfied.
