Fixing the broken home button of the iPhone 7 by yourself is not a good idea, the safest option for repairing the device is through an Apple-certified technician. Here's the reason why.

An independent repair shop can fix the broken home button of iPhone 7, but the Apple warranty will be invalid afterward. According to Motherboard, the iPhone 7 has a particular software lock that blocks the phone from unlocking when the key system that powers the home button is damaged or tampered.

It also prevents any third-party-installed home button that works with Touch ID or running on basic return-to-home-screen function. Only the original home button is compatible with the device unless the replacement is approved by Apple. This restriction makes it more complicated for an independent repair shop to fix broken screens since accidental damage to the home button could brick the device.

Apple has used this kind of method to prevent third-party fixes before. Last year, the owners of the iPhone 6 and 6 Plus fixed their devices' home button by themselves or by an independent shop only to have their devices bricked by an Error 53 message. Although Apple apologized for the glitch and immediately fixed it, the issue does not completely disappear.

One of Australia's top consumer agency, the Australian Competition and Consumer Commission (ACCC), ordered actions against Apple in the Federal Court of the country due to false, misleading, or unreliable representations concerning consumer rights after the lockouts issue.

Moreover, customers are asking for Apple and other companies to allow independent repair shops to have access to their products. The so-called "Right-to-Repair law" is still a controversial topic. It argues that having a better third-party repair helps the devices to extend lifespans and reduce e-waste, but companies worry about DIY home repairs and exploding phones.
