I've been using Pixels for years now, but despite spending most of my time with Google's flagships between reviews, I know I'm missing out on one or two of the phones' most useful features. This is especially true when new tricks and tools land with each feature dropcoming regularly throughout the year. Even for tech geeks, it's nearly impossible to keep track of everything, so Google includes its Pixel Tips app on all of its smartphones, and it pops up every now and then after an update to help refresh our memory.
