What's a good app I can use for my Samsung s6 that will help delete any kind cache or files. I know their is a lot like clean master and 360 security. What's a good one to keep my phone clean and running smoothly
In general cache cleaners are unnecessary and can do more harm than good. You can easily clear the cache from your settings if you think this is necessary, but there's no need to do it. Cache files exist for a good reason and they make your phone run faster and smoother, not the other way around.
