Apple's 4s screen is not sensitive, and it is still not sensitive after repairing and replacing the screen components. The store said that the handwritten "AC" chip was broken. Is that so? If you brush the machine In fact, some insensitivity is not necessarily because the chip is broken, but also because the chip is soldered in the pit and the contact is poor. Because the mobile phone will generate a lot of heat when it is used, the internal structure of iPhone is very compact, and it is easy to desoldering and virtual welding after long-term use.

In addition, if it is really broken, then the brush machine can't be repaired. Updating the phone is equivalent to deleting all the contents of the phone and reinstalling a system on the phone, especially in terms of software. The failure of the chip is a hardware problem, and the two have nothing to do in this respect.

If you can't do it yourself and can't find the position of AC, then admit it. In fact, the cost of a touch chip exceeds ten yuan, and 180 does. .......

See for yourself, your actual situation.
