Think back to when you last wanted to transfer some music or videos to your friend's smartphone and how difficult and slow it was. As powerful as our phones are, the default file sharing options are limited. There are, fortunately, some better options which make moving files easy, secure, and painless.
There are dozens of apps like Glympse, Family Locator, and Find My Kids that let parents see where their children's phones are, but they all have one fatal flaw: It's incredibly easy to spoof locations to make it look like the phone is somewhere else.
Will smartphone batteries ever last as long as we need them to? Perhaps not. That's why we rely on external batteries to help us stay connected for hours, even days, longer than usual. But in 2018, you don't want to use just any external battery. Modern Android phones have fast charging — so should your portable charger.
