In an ideal world, your Android phone would run like a dream forever. This being real life, we can’t always expect that sort of robust performance out of our devices. Things can happen that slow your phone and damage the experience. Maybe you install a lot of apps, and some of them are acting a little mischievous, or maybe something has just gone wrong deep down in the system where you have little chance of fixing it. At times like this, you could agonize over tweaks and possible fixes, or you could spend time uninstalling different combinations of apps. But maybe wiping the phone clean and starting over is the best overall option sometimes.
Kind of like a clean system re-install of Windows? No thank you.
