1: Check whether the running memory of the mobile phone is too small. Go to Settings -SD Card and Memory-Check the running memory. If it is much lower than the average, try to uninstall the software that is not commonly used. For systems above Android 2.2, non-system software can be moved to the memory card to save memory.

2. Check whether there are too many background processes. Press and hold the HOME key to open the task manager, check the running status of the background program, and try to close all applications.

It is recommended to download the software Android optimizer to clean up the background program and application cache garbage with one click.

3. See if the desktop effect is too complicated. Go to Settings-Display Settings-Animation-Turn off all animations to see the reaction speed.

4. Check whether there are too many security software installed on the mobile phone. View 360 mobile guards, mobile butlers, netqin security and other applications. If the hardware configuration of the mobile phone is low (such as Lenovo A60+), it is recommended to uninstall all security software. If the configuration can meet the requirements, it is recommended to install only one security software, and not too many security software of the same type.

The response speed of mobile phone is the same as that of computer, which is closely related to the hardware configuration and operating system version of mobile phone. If the response speed is still extremely slow or often crashes after passing the above tests, it is recommended to replace the mobile phone with a new one.

Thank you for your support to Lenovo and wish you a happy life!
