Why does the POCO F7 Ultra lag when using apps?

Thank you for your continued support. The POCO F7 Ultra has undergone strict professional inspection before leaving the factory, so you can feel free about the performance and reliability of your device, knowing that it has been thoroughly tested for quality and functionality.
When apps are continuously used, the device needs to perform memory recovery to optimize performance. This process is necessary to ensure that the system remains responsive, but it can occasionally lead to slight lags during transitions between tasks or apps. We will continue to optimize this scenario.
