Wondering if your smartphone is in good health? Whether it’s a used phone you just bought or an old device you want to sell, you can put it through a series of diagnostic tests. Some Android devices have built-in diagnostic tools, but the App Store and Google Play Store also offer third-party diagnostic tools.
