Websites and forums can be helpful in diagnosing problems with your smartphone and/or tablet, but even better would be an easy-to-use, dedicated application. Perhaps in recognition of that fact, Google released Device Assist today, an app for Nexus and Google Play Edition devices running Lollipop that can troubleshoot issues and proffer tips.
Device Assist tries to proactively prevent problems by offering suggestions. It’ll recommended changing your screen brightness setting to save battery, for example, or charging via wall port instead of USB. For more complicated issues, a handy button allows you to contact Google support and, if you so choose, submit device information for a presumably better tailored experience.
The app also provides a list of common tasks and how to perform them, like taking a screenshot and customizing notifications. Presented in the form of cards, most contain instructions in the form of either text or a video that can be saved or archived at will.
Device Assist is barebones now, but it might save you a few minutes on hold with Google support sometime. That alone is definitely worth the download.
If your device meets the requirements, you can grab Device Assist from the Play Store.
