Sometimes when I try to download/update an app I'll get an error after it's done downloading that says it can't install and it'll keep trying until I restart my phone and sometimes it works sometimes it doesn't also another issue whenever I turn my phone on or off it'll make apps dissappear and the only way I can access them is to do it in the playstore and I'll have to Uninstall them through the playstore and then reinstall them to make them visible
