The ZTE Avid 559 is a smartphone that runs Android 8.1 Oreo out of the box. Android 8.1 is a fairly new operating system version but it’s still more than a few years old already. Since apps are developed to run on the latest versions of Android (now Android 12) it can sometimes mean they drop support for older versions. Additionally, as developers add more code to their apps since the latest versions of Android can handle it, it naturally means those same apps may not run as well on older Android versions. Regardless, occasional lockups and freezes are a natural occurrence for every smartphone user, whether you run the latest version of Android or iOS. For that reason, Android comes with a built-in feature that allows you to take a hard reset to try to solve these everyday software problems.
