Why doesn't the screen light up when WhatsApp calls - briefly?
The screen may not light up during WhatsApp calls due to power-saving settings or display preferences that have been configured on your device. Additionally, certain apps and system updates can interfere with the normal functioning of screen illumination features.
Why doesn't the screen light up when WhatsApp calls - in detail?
When you receive a WhatsApp call, there are several factors that can influence whether your screen lights up or not. Let's delve into some of the key reasons for this behavior:
-
Power Saving Mode: Many smartphones come with power-saving modes designed to extend battery life by limiting background activities and reducing screen brightness. If you have enabled a power-saving mode, your phone might not light up the screen for WhatsApp calls to conserve energy.
-
Notification Settings: The behavior of your screen during a call can also be affected by your notification settings. Some devices allow you to customize how notifications appear and whether they should wake the screen. If these settings are adjusted to minimize screen activity, your phone might not light up for WhatsApp calls.
-
Do Not Disturb (DND) Mode: When Do Not Disturb mode is activated, it suppresses incoming call alerts and notifications to prevent disruptions. This feature can be particularly useful at night or during meetings. If DND is enabled, your screen may remain dark even when you receive a WhatsApp call.
-
Third-Party Apps: Some third-party apps and system optimizers might interfere with the default behavior of your phone's notification system. These apps can sometimes block notifications or alter how they are displayed, resulting in the screen not lighting up during a WhatsApp call.
-
WhatsApp Notification Settings: Within the WhatsApp app itself, there are settings that control how notifications appear. You can choose to mute notifications for specific contacts or groups, which might prevent your screen from lighting up when you receive a call. Additionally, if you have enabled "Show preview" in the notification settings, it could affect how the notification is displayed on your lock screen.
-
Screen Timeout Settings: The timeout setting determines how long your screen stays lit after you interact with it. If this setting is very short, the screen might turn off before a WhatsApp call comes through, making it seem like the screen isn't lighting up at all.
-
Hardware Issues: In rare cases, hardware problems such as a malfunctioning screen sensor or damaged display components can cause issues with the screen lighting up during calls. However, this is less common and usually accompanied by other noticeable display issues.
To resolve the issue of your screen not lighting up for WhatsApp calls, you should first check these settings on your device and within the WhatsApp app. Adjusting the power-saving mode, notification preferences, and DND settings can often solve the problem and ensure that you are alerted to incoming calls as desired.
