On my other android phones I used to factory reset regularly, especially after any update. For some reason I haven't done it once on my s7 edge, just sticking with it as is after every update. But I notice lag and battery life isn't all that so I wonder about trying a factory reset. But is it worth it? Does the edge still run smoothly and with battery life just as good as when it was released or is it the updates that have added the lag and reduced battery life?
