I'm developing a react native application and I don't know why some statistics are shown in my app (top left of screenshot), is there any way to hide this overlay?
This is the React Native Perf Monitor.
You need to open the Developer Menu and click Hide Perf Monitor.

I'm working on a native app that I want to display some pages in using React Native. I'm using react-navigation to handle a stack, and launching that in an Android activity (built according to the documentation for integrating React Native code into native apps) and from the similar instructions for iOS.
Once I enter the stack, I can navigate around it just fine - back navigation works with both an on-screen button calling navigation.goBack()/navigation.pop() and the Android hardware back button. The problem comes when I reach the top of the RN stack - I'd expect another attempt to pop from the stack or another press of the hardware back button to exit the app, but it doesn't; instead nothing happens when pressing the back button, and the on-screen button gives an error like:
The action 'GO_BACK' was not handled by any navigator.
and doesn't do anything.
How can I make back navigation from the top level of my React Native content seamlessly return me to the native app on both iOS and Android?

As I understand your question, you want to hide android navigation bar. There are 2 ways to achieve that:
Use React Native libraries: There are some libraries supporting you to hide navigation bar.

How to hide android system' s bottom navigation bar in React Native App without changing MainActivity? Maybe through AndroidManifest?
Write a simple native module to do that: First, you need to read React Native document about Native Modules for Android. If you know how to use that, you can start searching: "android hide navigation bar". For example: How to hide navigation bar permanently in android activity?
In case you have any problems about creating native modules, just provide information about them.
I am currently developing an application in React Native. There is significant performance drop when I run it on a Samsung Tab A (buttons visibly lag when clicked, a 3D animation we have takes very long to load in, etc.) I tried running the same application on a OnePlus 6T, and all these performance issues are gone. Obviously, the specs are better on a 6T vs. the Tab A, but why would tasks like button clicks even lag? This makes me wonder if the Tab A can support React Native apps at all. Does anyone have experience developing on the Tab A with React Native and have any advice?
