When should you not use Expo?

In my case, the issue was fixed by doing the following on my Android (Galaxy Note 5): Go to Settings > Apps > Application Manager > Expo . Scroll down to Draw over other apps and toggle it off and then on again . Close out of everything, re-open expo, and try connecting.

Expo is a toolchain based on React Native that will help you set up applications quickly . It provides many tools for the process of developing and testing Native React applications and provides you with the user interface and service components typically found in third-party Native React Native components.

Expo is a framework and a platform for universal React applications. It is a set of tools and services built around React Native and native platforms that help you develop, build, deploy, and quickly iterate on iOS, Android, and web apps from the same JavaScript/TypeScript codebase .

Expo can automatically sign your app for iOS and Android . If you don’t want help from the Expo team, you have to do it by yourself. You will have some requirements that you must do if you want to push your application to the store.

Your project will always run in one of two modes: development or production. By default, running your project locally with expo start runs it in development mode, whereas a published project (via expo publish ), or any standalone apps, will run in production mode .
