The Apple 6s screen touch failure is divided into intermittent failure or complete failure, which are generally caused by the following two reasons:
The external cause is usually man-made: the phone has been in the water, dropped or repaired.
Internal reasons are generally system failure: download and install some incompatible apps, mobile phone swiping or firmware upgrade, and jailbreak is not perfect.
I've been working at Apple repair centers, and I've seen this a lot. First of all, let's talk about the three-layer structure of the 6s screen:
The first layer is the Corning Chimpanzee external screen, the second layer is the touch screen, and the third layer is the LCD screen.
The touch control function is directly related to the touch screen and the motherboard touch ic
If the full screen touch intermittently or completely fails, try restarting the iPhone first by:
Press the \"Sleep\/Wake\" (also known as the power button) and the Home button at the same time until you see the Apple Logo on the screen.
Second, if the problem of touch failure remains after restart, it is proved that the screen touch failure is caused by the following two reasons
The handling method of the failure caused by the short circuit of the touch screen wiring: If the phone is not insured, it can apply for after-sales service directly. If the phone is out of warranty, you can find a reliable third-party repair shop to replace the screen repair, generally reliable repair shop with screen separation equipment, screen pressing equipment, defoaming machine. Some of the better repair shops also have a dust-free operating space.
Handling method of failure caused by the motherboard touching the ic: If the phone is not insured, it can directly apply for after-sales service. If the phone is out of warranty, you need to find a chip-level technology repairman directly to replace the touch ic.
In summary, when the screen fails, the after-sales service is generally regarded as artificially caused, not to give free insurance, and even sometimes the price is also refused to replace or repair. In fact, sometimes it is only about 200 yuan to repair a small problem, but you need to find a reliable master of ashes level for testing and maintenance.
