While certainly faster than writing by hand, manually typing passages from a book or document can be slow and frustrating. But thanks to Google Assistant, this is no longer the case. Whether you need to quote text for an essay or need to win an online argument, all you need to do is point your phone's camera at the paper and tap a few times.
If you're not familiar with Bixby, I don't blame you. The Samsung assistant was released two months ago with the Galaxy S8 and S8 Plus. While users were excited about this Google Assistant-like feature, they were ultimately disappointed by the limited rollout of only some of Bixby's features. Now, Samsung is hopeful to perfect Bixby using you.
Sometimes it's impossible to concentrate — let alone direct your personal assistant Siri — when someone is blasting music on their phone or talking to thin air. I mean I'm loud, but not that loud.
Anyone who needs to use their iPhone hands-free knows how useful Siri can be. If you can't look at your iPhone, but still need to read and reply to messages, Siri has your back. Third-party applications have traditionally been unable to utilize this feature, but now that luck has turned for Facebook's other popular messaging service, WhatsApp.
Google's personal messaging service Allo could reveal your search history and other private information to friends if the Google Assistant bot is called upon in chats, according to a story from Re/code.
The Google Pixel and Pixel XL have an exclusive set of navigation buttons that you can't get on any other device without some tinkering. But aside from just being solid, filled-in shapes, the real treat in the Pixel's nav bar is the Google Assistant animation that gets activated by long-pressing the home button. The four colored dots that animate outward give you some visual feedback for triggering the Assistant, but really, it's just a nice little touch.
While Siri may be the cream of the crop when it comes to smartphone personal assistants, there is always room to grow bigger and better (that's what she said). Siri, although recently expanded, is still lacking in the amount of commands and actions she can currently perform. While looking up directions and restaurants is fairly easy for Siri, asking her to gain access to third-party programs or browsers is a little more difficult.

One feature of Samsung devices that's less useful than I had expected is S Voice, the voice assistant that ships with all new Galaxy devices. The voice is annoying, the features are lacking, and it's an all around subpar product. With Google Now, Siri, and now Microsoft's Cortana, Samsung needs to really step up their game—even on the new Galaxy S5.
While the Galaxy S10 is a beautiful phone, its software isn't for everyone. One UI makes huge strides toward undoing the mess known as TouchWiz, but for purists, it's still not quite on par with stock Android. Fortunately, the beauty of Android is you can change this with a few apps.
Google collects an enormous amount of personal data. While some of this data is used for targeted ads, others tidbits of info such as our location are used to improve our mobile experience. While it is natural for us to distrust Google's intentions, by allowing their data collection, we can add new functionality to our favorite apps.
