Yesterday I noticed that my minimize and home buttons were not working again. As a result, if I want to minimize, go to home page or exit an app I will have to reboot the phone. Currently it is just the back button that is working. Please what could be the fault

simply restore factory settings,but backup your important files and know ur gmail and passord in case of frp lock.
