Qq can't find the calls made ten years ago because qq won't keep all the call records forever. QQ calls are social media functions, which are generally kept for a period of time, but not all call records are kept permanently. QQ will be updated several times during its operation, and the previous call records will be cleared or restricted, so it is impossible to find the call records ten years ago on QQ. QQ is a popular instant messaging software in China, which provides functions such as text, voice and video calling. Developed and launched by Tencent, it was established in 1999. After the popularity of smart phones, QQ also has mobile applications that support cross-platform use.
