When it comes to non-responsive display on the iPhone it is for sure a situation that every owner of this device would like to avoid. For technicians, this is kind of a hard nut, and there can be several causes. Even though the problem of non-responsive iPhones is a thing of the past and new models rarely suffer from this ailment, this problem is still very topical in the field of used equipment.
So, in order to make it easier for you to repair the display on the iPhones, we decided to write down the 4 most common reasons for the "loss of dockability" of the display and how to deal with them.
Even though the iOS operating system is in most cases an extremely reliable and stable system, older devices may already have problems that did not exist before.
A well-known (though infamous) problem was, for example, the version 11.3., Which caused many iPhones 8 and 8 Plus to get stuck on the home screen - this problem occurred especially in devices where the display was replaced in the past with a non-original and poor quality replacement part. The simplest solution in this case was to update your device and the problem disappeared in most cases.
In English, the popular term “ghost touch” represents a situation where there is an unintentional pressing or other interaction on the iPhone display, which the user did not perform. Solving this problem may be among the most problematic. The most common solution is to reinstall the display. During the installation itself, we recommend using antistatic gloves, which prevent possible damage by electrostatic discharge, which is also one of the possible reasons for accidental contact. If this is really true, you need to replace the display with a new one.
Sometimes the solution can be quite easy. Just check that the display has been properly installed on the device - you will often find that this is not the case and you will need to reinstall the replacement display. However, beware of flex cables and connectors that could theoretically be damaged.
If the display is only partially responsive after installation, it is essentially certain that it has been damaged (probably already during production). Such a display needs to be complained about and a new one installed.
As we have already mentioned, when replacing the display on the iPhone, it is extremely important to choose not only a quality spare part, but also suitable accessories for mobile phones, or quality service tools that will reduce the risk of damage to the device to an absolute minimum.
