After updating the app if a WhatsApp user is on a call, they will get an alert to accept or decline the call. Before this update, whenever a WhatsApp user was on a call, the second call would automatically get disconnected and they would see a notification later after the call ended.Along with this feature, this app update also brings updated group privacy feature. Thanks to this feature, WhatsApp users can control who can add them to groups. Along with this, WhatsApp also rolled out a bug fix for an issue that several users reported led to massive battery drainage.As mentioned above, the call waiting feature was rolled out to iPhone users in the last week of November, along with some new features. As part of the WhatsApp app update v2.19.120, the iOS app for WhatsApp now comes with updated chats screen that is said to quickly scan messages. Besides that, the update also allows users to directly send WhatsApp messages from Braille keyboard when using Voiceover mode.Earlier this month, it was reported that WhatsApp is working on rolling out Dark Mode that can be turned on with the battery saver mode on the handset. Spotted in the Android beta update version 2.19.353, this feature allows users to switch between the Dark Theme and the Light theme in sync with their battery saver functionality. This means that when the smartphone user will opt for the Battery Saver mode, the theme in WhatsApp will automatically switch from Light to Dark.
