Where is the after-sales maintenance of jinniu district Apple's mobile phone that can't be turned on?

Hello, I have been to an Apple mobile phone repair network near jinniu district. The specific address is Room 0 1 Floor 8, No.9 Jianshe Road, chenghua district, Chengdu. You can take your equipment to have a look, hoping to help you.

When you use Apple's iPhone, you will encounter the failure of black screen more or less. Generally speaking, the black screen is caused by the software system, which can be solved by some manual operations. Here are some simple ways to deal with the black screen of Apple's mobile phone crash in daily life.

Method 1: Force the phone to restart.

When Apple's iPhone crashes and doesn't respond, we can try to hold down the "power and home screen" buttons of the phone at the same time and keep them above 10 second.

If the forced restart is successful, you can see the Apple logo on the screen.

After the restart is successful, you can use your mobile phone normally. In addition, for some friends who like to escape from prison, they may often encounter the problem of automatic restart of mobile phone crashes. Also, I like that when the mouse updates the iOS test firmware, it will crash and the screen will be black. These faults can be solved in this way first.
