However, the problem of the dark screen when iPhone calls is often overwhelming.When this happens, users may think it is a hardware failure, but in fact, the problem of dark screen when iPhone calls is usually software-related. In this article, I will introduce you to some reasons why the screen may be dark when making iPhone calls and provide some solutions. Reason 1: Distance sensor fault The distance sensor is a kind of sensor that can detect the distance between the mobile phone screen and the face. During the call, this sensor can turn off the screen to avoid the impact of facial touch on the call. In some cases, the distance sensor may fail, causing the screen to be dark during the call. To solve this problem, you can try to gently cover the distance sensor during the call. If the screen lights up again, it is a problem caused by the failure of the sensor. Reason 2:iOS update problems In some cases, iOS updates may cause certain problems, such as darkening the screen during calls. If you notice that this problem occurs after the recent iOS update, it is recommended that you check whether there are other available updates in the iPhone settings. If there is no new update available, you can try to restore to the previous iOS version to solve this problem. Reason 3: Custom setting problem In the iPhone settings, you can make many custom settings, such as turning on or off the automatic screen brightness adjustment function. If you adjust these options and encounter problems with the screen dimming during the call, you can try to restore these settings and restore them to the default settings, or check if there are similar settings that may cause this problem. Reason4: Hardware failure Although the problem of dark screen when iPhone calls is usually related to the software, in some cases it may also be caused by hardware failure. For example, there may be a screen contact problem, resulting in a screen problem during the call. If you have tried the above solution but the problem persists, it may be caused by a hardware failure. In this case, you'd better send your iPhone for repair to solve the problem. To sum up, in your daily call, the problem of dark screen when making iPhone calls may occur at any time. Although this problem is usually related to software problems, it may also be caused by hardware failure in some cases. In this article, I provide some reasons that may lead to this problem and possible solutions.
