In order to find a solution to the software bugs on a Lenovo tablet, the first steps include checking and updating the system software (many bugs are resolved with official patches), clearing app caches and storage by using the device settings, uninstalling apps that do not appear to work, and rebooting the tablet to reset system processes. When those measures fail to help then backing up your valuable data and doing a factory reset can help erase more in-depth software corruption and then a factory reset of the computer may be required, not to mention visiting Lenovo support or professional repair facility.
