Recently, I have received several unwanted phone calls, including those from Aliyun, automated voice messages claiming I have won prizes, and others. Some of the numbers I have added to my block list, as I find such calls frustrating. Within the App Store, I have discovered several options to manage these unwanted calls, such as Tencent Mobile Manager, 360 Mobile Guard, and Baidu Mobile Guard. While these apps do offer various features, they tend to collect device information excessively. Having experienced this, I look for alternative apps that can effectively block unwanted calls. If anyone has any recommendations, it would be appreciated, preferably apps similar to 'Kunikuri SMS'.
